Processor's Mind

Einhard's: Beginners guide to making your own Personal Computer : Part 4 - RAM

2008-10-27T20:54:00.000-07:00

The RAM is one of the more important part of the computer when it comes to determining the speed o the computer.

No matter how good the processor of a computer if the RAM is bad then everything fails.

The RAM we are talking about right now is DDR2 and DDR3 SDRAM because this is what is used in common computers.

Take note that a DDR is commonly named in either one of the following formats

first is something like "DDRtype" - "Data transfer per second" so an example of this would be something like DDR2 - 800 and DDR3 - 1333

the second format is something like "PCtype" - "Peak transfer rate" example of which would be something like PC2 - 6400 and PC3 - 10600

note that PC and DDR are both actually referring to the same type of RAM the only difference is the data that is shows.

to know the equivalent PC model name of a DDR model name simply multiply the Data transfer per second by 8 (8bits = 1 byte)
so DDR2 - 800 = PC2 - 6400

and to know the DDR model name of a PC model name just divide the peak transfer rate by 8
so PC2 - 6400 = DDR2 800

obviously enough Data transfer per second refers to the number of bits the RAM can process in a second (in millions so for example DDR2 - 800 means that it's transfer rate is 800 million bits per second).

Peak transfer rate refers to the speed by which megabytes are transferred per second (PC2 - 6400 can transfer 6400 Mb/s)

to get the Input/Output bus clock divide the Data transfer per second by 2 and change the unit to MHz

To get the memory clock of the RAM divide the I/O bus clock by 2 and retain the MHz unit..

So what is the better RAM? Well obviously the better RAM is the faster and larger ones =D. Be sure though that the RAM you choose is compatible with your motherboard ^_^

Einhard's Beginners guide to making your own Personal Computer: Part 3 - Motherboard

2008-10-19T00:26:00.000-07:00

Alright today we will be talking about motherboards. Now for me the motherboard is the body of the computer and I would like you to think of it that way.

Why is it the body of a computer? It is because all parts depend on it.

No matter how good the parts are, if the body is weak then the entirety of the computer will be weak. For example even if a person has an incredibly good brain if his body is weak then his brain will easily wither and die with his body. If the body is sick all other parts will suffer. If the body is weak no matter how good your feet are you can't be the best because of your weak body.

Why am I telling you those things? It's because I want to stress the importance of picking a good motherboard and the importance of thinking of it as the body of the computer.

More often than not people tend to disregard the quality of the motherboard. I know a lot of people would buy good processors, video cards and a high amount of RAM and then they will look for the cheapest motherboard that is compatible with those parts. The thing is because they do this their high-end parts without their knowledge is actually not able to use 100% of it's capabilities.

So how do one pick their motherboard?

First of all limit your choices to motherboards that are compatible to your processor.

Then further limit your choices to motherboards that are compatible with your Video Card because Video Cards are subdivided into AGP and PCI-E (which will be discussed later on) and is further divided into ATI Radeon and Nvidia GeForce video cards

Next limit your choices on your preferred maximum RAM that can be placed on the motherboard also take note that RAM's are also subdivided into many frequency and types so you have to limit your choices accordingly.

Next limit your choices to other optional things like the built in LAN, Audio , Number of USB ports, Overclocking capabilities, Number of customizable ports etc.

Once you have limited your choices into a handful of choices do research on them first because chances are there will be some almost similarly prized motherboards with big performance gaps.

Well that's all for today hope you guys learned something ^^

Einhard's: Beginners guide to making your own Personal Computer : Part 2 - Processor

2008-10-14T18:21:00.001-07:00

Ok so here is the long delayed (sorry about the delay it's because of our consultations at school) second chapter of my guide to making your own personal computer.

Today we will be talking about processors. So why is it that I made the processor the first part that one should pick when making a computer? Well it's pretty simple because it is the core of the computer.

So how should one pick a computer? Here are some guidelines on things you may need to ask yourself before buying a processor
1. Am I a power user?
2. Am I going to use my pc primarily for games?
3. Am I a multi tasker?
4. How much processing power do I really need?
5. Do I just use computer for things like ms word?

By answering those questions you will be able to properly pick your computer.

Anyway you may want to look at my older articles to understand processors better.

In a nutshell however here are some processor recommendations

Power Users and multi taskers benefit from more cores, gamers would benefit more from dual cores with higher clock speeds and for those who use their pc only for office will benefit more from a single core processor with high clock speed

2008-10-10T03:44:00.000-07:00

Alright since it will be sem break soon and I have a lot of time to post stuff I'm going to create my very own "Beginners guide to making your own Personal Computer" It will be divided into parts in this manner.
1-Introduction
2-Processor
3-Motherboard
4-RAM (Random Access Memory)
5- Video Card
6- Casing
7- UPS (Universal Power Supply)
8- Cooling System
9- Speaker
10- CD/DVD/Blu-ray Drive
11- Keyboard and Mouse
12- Monitor
13- Operating System
14- Modems,LAN Card, Printers, Scanners
15- Peripherals and Accessories
16- Sample Computer Systems

Ok so some of you might think that the ordering of the parts are weird but to me that is the best order because I think that is the best order of doing things when building your own personal computer ^^. Look forward to my future posts I think I might post one article every other day ^^

Have a great day everyone

Correct Programming in C++

2008-10-04T18:13:00.000-07:00

This time around I'm going to give tips to those aspiring programmers out there ^^.
I'm going to list some of the most basic correct programming practices to help new programmers avoid Common Programming mistakes in C++.

1. Start your programs with int main(void). If you want to know the reason then Google it ^^

2. ALWAYS properly name your variables.

3. If possible initialize the values of variables as you declare them.

4. Avoid using scanf

5. Comment a lot

6. Use functions on everything that can be used as functions

7. Utilize the header files as much as possible

8. Don't add header files that you are not going to use

9. Return a value for functions that need something be returned

10. As much as possible avoid using global variables.

RAM question and answer.

2008-10-02T02:37:00.001-07:00

Here are some of the more common questions about RAM

Why is RAM called memory even though our files are stored in the Hard Disk?
-Because the memory processed by the processor are stored in the RAM thus therefore it is the primary memory (because of it's hierarchy in processing) and is rightly called memory.

Does having a larger RAM size make it better?
-No. Not because a RAM has a bigger size doesnt make it always better compared to another RAM with a smaller size. Why? Because of RAM frequency

What is a RAM frequency?
-It is basically the speed by which the RAM can input/output memory from the secondary memory and to the processor although of course it is a lot more complex than that.

Can I just plug in any RAM in my computer when Upgrading RAM?
-No. Your RAM largely depends on your Processor and motherboard. If your motherboard/processor is not compatible with a RAM frequency and yet you plug it in you will break your PC. Also if you are adding a RAM make sure that both of your RAMs have the same memory else you will break your computer.

What are those SODIMM RAMs?
-They are the RAM's of laptops

What is the best RAM nowadays?
-DDR3

What does RAM stand for?
-Random Access Memory

hope you learned some stuff ^^

Basic Internet Account Security Tips

2008-09-27T20:35:00.001-07:00

So this week I'm going to share to you some tips on making your internet account safer. With a lot of hackers roaming the net these days our accounts can be easily be targeted by some off them. SO how are we gonna protect ourselves from them? Here are some tips for protecting our internet accounts.

1. Malware Scan every day. Scanning for malwares every other day is no good. To protect your pc from viruses,keyloggers,spywares, rootkit and the likes you have to scan your pc everyday for them.

2. Never use passwords that are related to you personally. For example using your birthday as a password makes your acccount easily hackable.

3. Use long alphanumeric characters ,symbols and big and small letters on your passwords

4. Never use the same password in accounts that are important

5. Never use REAL answers as answers on your Secret Questions

6. Never give out your password no one ever needs them except you. Most especially not someone from the company who you use the password for.

7. As much as possible do not acccess your account on computer shops.

8. Memorize your passwords don't write them down as much as possible

9. Never give anyone event a slight hint on what your password may be

10. make sure that your password is pure giberish and not something that has meaning for example.

IlOvECooKiEs^%#677475 can be easily guessed compared to a password like a*t08nVda5#qWp

hope you learned something take care guys ^^

How can I keep my desktop as cool as possible

2008-09-24T02:16:00.000-07:00

This is a very usual question in the internet. A lot of users (including me in the past) likes to ask this in forums with many experts. Sadly I never got a good answer because a lot of people would tell me something like add some fans and ventilation or buy a liquid cooling system and put it in my machine. Although I never got that good answers from forums I have experienced a lot already so now I know some ways to keep your desktop as cool as possible ^^. Here are some of the ways I found to keep your PC cool.

1. More Space = Cooler
I'm sure you have experienced being cramped up in a place where there are so many people and that it's very hot when cramped up with all those people? It's the same with computers. If your Casing is small and the components of your desktop computer is cramped up your computer will get hotter easily.

2. Arranging and grouping wires
This is actually more like a continuation of number one. Having bad wiring in your desktop computer can cause ventilation and the flow of wind to be very bad thus making your computer heat more.

3. Look for good ventilation and fan placement in your casing
Because you have many ventilation and fan in your casing does not mean that your computer will be cooler. You have to find good places to place your fans and ventilation or else they may be worth nothing at all.

4. Cooler environment = cooler desktop
Of course if you studied physics you will surely know the reason behind this. Anyway to explain this in non technical terms if the environment is cold then of course the startingg temperature of your computer is cold and the wind you get from the environment is cold... so less heat ^^

5. Identify the parts that heat up the most and concentrate on cooling them
Usually a computer has some parts that tend to heat up very fast and if you don't cool them faster chances are they will infect the surrounding components with their heat. Being able to at least slow their heating or reducing the heat these components emit will be a very big help in cooling your desktop

There you go I do hope my tips are very helpful ^^

2 computer myths and the truth to them

2008-09-20T20:01:00.000-07:00

Here are some common computer myths and what I think are truth behind the myths ^^

1. Computers die (would not open again) if not used for a long time.
Myth status: Partially true
- Indeed not using your computer for a long time (like 3 months or more) can cause your computer to not open but sometimes it can still open easily. However it is easy to repair this kind of problem. Unless your computer emits smoke or creates a blast like sound after you try to turn it on chances are it can still open. To open a computer that hasn't been opened for a long time you can try to plug it on for a long time without opening it then open it afterwards. You can also try to manually spin the power supply's fan while constantly trying to turn on your computer. There are a lot more simple solutions to this problem.

Why does this happen? There are lots of causes some includes build up of dust. The battery on the motherboard losing power and a lot more. Technically your computer doesn't die it just gets some problem because of being standby vertime ^^

2. Screen Savers save battery
Myth Status: False

Screen Savers does not save battery. It's the same as leaving your computer idle for a long time. Turning off your monitor does save battery however. So next time instead of putting on a screen saver just turn of your monitor.

Personally I think the point of screen savers is to protect whatever it is on your screen that you left (generally to not let anyone view it while you left it).

IT Certifications must have for Philippine IT students

2008-09-16T05:38:00.000-07:00

So how do one earn an edge in IT when there is no board exam to rank you?

The answer is certifications! There is a common misconception though that in the world of IT Quantity and not Quality of certifications is more important. I would like to clear that Quality is better. An IT student must have good Quality Certifications in his or her chosen field in IT. Here are some of the more important qualifications for IT students.

All IT fields:
PhilNITS - This one is hard to get mainly because it requires you to pass a Japanese level IT exam. The good part is that if you pass this you have a huge edge against most of your competitors because only few pass this exam. Aim for this ^.^

Networking Field:
Cisco Certifications - There are a lot of cisco certifications. There is CCNA, CCDA, CCNA Security, CCNP, CCDP etc etc. Check the certifications at Cisco's website for more details on these certifications. Basically though you have to get cisco certifications on your specific networking field. Example: Network Security path needs you to get CCNA Security to get associate rank CCSP for professional rank and CCIE security for expert rank. ^.^ good luck on this one.

Programming Field:
Sun Certifications - There are also a lot of these too and the worse part of this is that it takes one year to get every certification (assuming you pass). ^.^ In this one I think you really have to choose carefully or else you will be wasting your time.

Other Recommended Certifications:
Get certifications on popular langauges like C,C++,Java,XHTML,PHP,MySQL and the likes ^.^

Good luck on getting your certifications ^o^ Good Luck to me too =D

Basic Comparison of some programming langauges

2008-09-16T05:20:00.001-07:00

Comparisons of Programming Languages

There are a lot of programming languages and thus it is impossible for a programmer like myself to actually learn and become extremely proficient in all programming languages. So I've compiled some of the more popular programming languages so that you like me can also choose the programming language you will like to learn ^^.

Basic
-BASIC or Beginner's All-Purpose Symbolic Instruction Code is a programming language that is used to create Applications or used for Educational Purposes. The Main Goal of BASIC is to be as simple as possible. Basic is a procedural programming language. This programming language is not really suited for programmers who wish to earn money.

Assembly
-Assembly Language is a code made to somehow simplify machine code. This programming language is powerful and can be used for general purposes (meaning it can be event-driven, procedural etc.). Great Assembly Programmers can usually get good pays at big companies.

C
-C is an imperative programming language (a combination of Procedural and Declarative programming language) and it is also an object-oriented language somehow. C is mainly used to create systems because it has low constraint level and it has access to low levels of the computer.

C++
-Basically an improved version of C. It is more efficient and is used usually for creating applications and systems.

JAVA
-An imperative, object-oriented, generic and reflective programming language. It is mainly used for creating small and portable programs. It is special in a sense because it has an automatic trash system.

Perl
-An imperative,procedural, reflective,functional, object-oriented and generic programming language. It is a very powerful scripting programming language. It is even the programming language used to create third party programs for a lot of popular games like Ragnarok.

PHP
-An imperative, object-oriented and reflective programming language. It is used for web and server side applications. This programming language is very simple and thus requires less amount of effort to learn. This programming language can earn one good money.

Python
-In a way it is an improved version of Perl. It is simpler, more expressive and a lot more readable.

Visual Basic
-A VERY simple programming language although somehow weaker than most of the other programming language. The .NET version of Visual Basic is powerful though. It is mainly used for applications.

I will explain the types of programming langauges on my next post ^o^

Knowledge is POWAH!!!

How to play most video and music file formats

2008-09-15T06:53:00.000-07:00

When I search and browse through computer related forums or surfing the internet I often see a lot of questions like. I can't play X video file!!! How can I play X video file?!?!? Windows Media Players says it can't play my video file. Why? or something like those questions.

Today I'm going to answer those questions in the least technical way. Actually it's more like I'm going to tell you how to play them without actually teaching you the technical stuffs.

So first and foremost the problem is you don't have a codec for playing the file you want to play. What is a codec? codec actually has no official meaning. Some people says it means coder/decoder while others says it means compression/decompression, I say, If it has no official meaning then it doesn't all I know is that it is needed to code and decode digital data streams and signals.

SoOoooo now that you know what a codec is how is that going to help you?

Well basically you have to download a codec for any video and audio file you want to play... But I won't make you search for them individually instead I'm just going to recommend some stuff to you.

First you can just choose to download VLC media player. Just type VLC media player in google and it should be the first one in the list. VLC media player as it advertises really does play almost all major video/audio file formats and most minor video/audio file formats.

If the first recommendation does not work download the Media Player Classic and the Combined Community Codec Pack(Again search them in google the first link would be the right one). With this and VLC your computer would normally be able to play almost all public video file formats.

Beware though that some Vista users and a little XP users says that having both of my recommendation above at the same time can cause some slowdowns in some lossless video file formats when using a slow computer.

Usually though you won't have any problem with it... I don't...

Hope I helped you guys ^_^ God Bless!

How to fix a HD Realtek Audio Problem (In most computers)

2008-09-15T04:32:00.000-07:00

I recently encountered an audio driver installation problem while installing it in my bestfriend's new computer.

Because I tried searching the net for a cure. I found out that this problem is very rampant. In the end I wasn't able to find the cure in the Internet (perhaps my search key words were wrong), but in the end I managed to find a way to correct it and install the driver properly.

So here's how to fix it.

1. Go to Control Panel>Add/Remove Programs and uninstall anything there that has Audio/Sound on the program's name (This is assuming that you're computer is newly formatted if it's not then you have to know which ones are the programs associated with the realtek driver)

2. Go to Start>right click My Computer > Properties >Hardware >Device Manager

3. At Device Manager go and look for the Sound,Video and Game Controllers and double click it

4. Double Click Legacy Audio Drivers > Properties > Then remove everything under multimedia devices. Then click OK.

5. Still at the Device Manager Double Click Realtek High Definition Audio > General > Device Usage (Change it to disable) > Driver > Unistall > Yes.

6. Now Restart your Computer

7. After turning on your computer. Cancel "ANY" prompts by Windows about audio drivers.

8. Now install the realtek driver from your Motherboard's CD (Or whatever CD you're using). If any prompts by windows comes up again about drivers... CANCEL them.

9. Restart your Computer again after installation.

10. You now have sounds congratulations ^_^

Hope I helped you out too as I have helped my bestfriend =D

How to know your download speed (in kilo bytes)

2008-09-15T04:31:00.001-07:00

What the heck? Do we not know our download speed already? Isn't it already equal to my internet speed? The answer is NO you don't know it yet.

And that's the point of this post. ;)

To enlighten you about that fact ^^.

People tend to ask things like my internet provider says that my Internet speed is 1Mbps how come I can only download 40 kb/s? They're cheating me! Well let me tell you now. THEY ARE NOT CHEATING YOU. You just have been simply ignorant of some things ^o^. But don't worry I'm now going to teach you the way to properly know your download speed so you would know if they really are cheating you or not =D(If that's your concern). Or to know your maximum download speed.

First things first. Why is it that even if my Internet Speed is 1Mbps I can only download at a speed of 80 kb/s?
-That is because of a common misconception "Bit Rate" the "Data Transfer Rate" of computer stuff is not measure in bytes but in bits (That's why it is called bit rate duh). That means when your LAN says 100.0 Mbps it means 100 Mega bits per second, When your internet speed says it's speed is 1Mbps it means 1 Mega bit per second the same rules goes for any "Data Transfer Rate" in any computer stuff like bluetooth etc. And that's where everything goes wrong. If you know that fact all you have to know are the conversions so you can actually compute for your download speed =D.

So now here are the conversion factors
8 bits = 1 byte
1024 bytes = 1 kilobytes
1024 kilobytes = 1 gigabyte

Thus, An internet speed witth a speed of 1Mbps will have...
1,000,000 bits * 1byte/8bits = 125,000 bytes
125,000 bytes * 1kilobyte/1024 bytes = 122.07 kilobytes

Thus a 1Mbps internet would have a maximum of 122.07 kilobytes per second download bandwidth.

Do note however that usually your computer never uses all this for downloading. Usually you only get to enjoy 60-80% of this due to server-computer issues and lots of other technical stuff.

The same computation goes for Upload speed ;)

So that's that hope you learned something =D

Added Knowledge: Do you know that music and video formats are also measured in bit rates. That is bitrate there represents the amount of information stored per unit of time of a recording. For example a Blu-ray disc is 54Mbit/s (That's why it looks so clear) while a VCD has a bit-rate of 1.25Mbit/s (No wonder it looks nothing compared to DVD's and much more against Blu-rays).
I may discuss bit-rate and what it really is in the near future watch out for it ;)

A general guide understanding your processor

2008-09-15T04:30:00.001-07:00

Most people blindly pick their processors when buying computers. Some just rely on a processor's reputation or blindly pick a processor by it's clock rate without really knowing that clock rate is just one of the determining factors of the overall processor speed.So how are we really supposed to pick a processor?

Here are ways to actually determine the overall performance of a processor.

1.Integer Range
-If you look at Vista Operating Systems you find that there are 32-bit and 64-bit versions of their OS. That 32-bit or 64-bit is an Integer Range of the Processor(meaning you can only install 64 bit version of vista on a Computer using a 64-bit Processor. To put it simply it's the range of number your computer can deal with. Fore example a 32 bit computer can deal with a range of numbers that can be represented by 32 binary digits (each digit either 1 or 0), that is, 2^32 discrete numbers. It also affects the number of memory locations a computer can locate but that's too technical so I'm not going to discuss that any more.
- Anyway a processor that has a higher Integer Range is faster even if both processors have the same clock speed.
-If I am not mistaken all Core2Duo's and Quad are using 64 bits architecture. Usually you have to research this first because it's not always specified by the processor's box or specification.

2.Clock Speed
-This is the Mhz or Ghz you see at a Processor's Specs (AMD doesn't usually include this though instead they put a number like 5000+ so you have to research their clock speeds). Basically a computer with a higher clock speed is faster.

3. Number of Cores
-Of course a computer with more cores are faster than a computer with one core. A common misconception, "a two cored processor is twice as fast as it's single core processor" THIS IS WRONG. Indeed a two cored processor is usually faster than it's single core processor counter part but it is never twice as fast nor is it always faster. Why? Well it will take a lot of time to actually explain so the bottom line is that as of now more cores means "usually" faster.
-Note: Dual Cores (for now) are usually faster than Quad Cores in running many programs(Because only a few programs support multi threading for quad cores and other technical reasons) but Quad Cores are definitely faster it's potential is just not being fully utilized yet.

4. Architecture
-This is actually the one that most people do not take into consideration when choosing a processor. This one is actually incredibly hard to explain(Even I don't understand it completely). However in a nutshell.

Core 2 Quad > AMD Phenom >Opteron > Core 2 Duo > Athlon X2 > Turion X2> Core Duo > Pentium D > Celeron > Pentium4/Athlon/Turion
(I don't know where Intel Atom lies because it's new but I know that the reviews it got was poor)

5.Cache
-This is the where the Processor stores and access frequently used stuff. So Basically a computer with a higher cache is faster (that is assuming, as always that the processors you are computing have the same clock speed)

So that's it hope you learned something ^o^

How to avoid/lessen Computer Lags

2008-09-15T04:28:00.000-07:00

One of the most irritating experience you can ever have is when you lag while using your computer. Especially if this happens very frequently! Sometimes the lags are extremely frequent that you even want to smack your computer! Is there no way to remove lags? Sadly there isn't a way to completely stop any computer from lagging (Yes even if your computer is the best out there right now). There are ways however to reduce lags. So how do we reduce lags? Here are 10 ways to reduce lags ^_^

1. Know your computer and it's limitations
-Do not force your computer to have a workload that surpasses it's limitations. If you have a single core computer for example avoid using many programs at once because doing that makes you lag more. If you have RAM that is less than 1gb also avoid using many programs at once because doing that will also make you lag ;). Remember that the best way to reduce lag is to avoid using to many programs in a computer at once ^_^

2. Get a better Internet Connection
-For lags in online games and internet surfing this is of course one of the best ways to reduce lag. The faster your internet connection is the less lag you will experience online.

3. Close useless background applications
-A computer runs several background applications (especially in vista). There are some background applications that you never use or are just overkill (examples of these are those many many extra "protection" that vista offers when you already have your anti virus, firewalls etc) close them to speed up your computer and lessen lag.

4. Disable Services you don't need
-Computers usually have hundreds of Services that runs on startup disable those that you don't use. Ask experts to do this if you're not good with computers because you might hurt your computer if you do this without knowing what you're doing >_< now ="P.">Vista
Even if you have a relatively good computer installing Windows Vista on it eats up a LOT of ram [an average of 400+MB RAM is eaten by Vista. The Vista Ultimate Edition eats 400-700 MB RAM on average]
-I don’t recommend vista for computer with less than 1gb ram or has a processor slower than core 2 duo 2.4 Ghz stick to XP if you really want to use vista get at least 2gb RAM (Oh yeah before you add more RAM to your system note that 32-bit Vistas only accept up to 3.12gb ram if I am right)

XP
This is a good OS just make sure you’re using a stable version of it by my experience Windows XP sp2 ver 2.0b is the most stable one out there (but I’m not an expert so don’t completely trust me over this I just said my observation)

Win 98
This one is a really good OS it eats up very little resource although it is a lot less user friendly than xp and you would have to checck for software compatibility (But usually programs are backward compatible except for programs designed for 64 bit systems)

Linux,Mac and other OS that are not windows
Linux is Good. I don’t really know about the others… Sorry
-I would recommend Linux but a lot of people might have a hard time adjusting to it

Other window systems
Windows ME - ManyErrors
Windows 2000 - 2000+ Error and Error prompts
Windows 95 - Good but 98 is better IMO

8. Defragment and Scan Disk at least 3 times a week
-Defragment your hard disks and keep your hard disk memory as free as possible Defragmenting is basically in non technical terms is placing stuff in your memory in a way that it is orderly so that your hard disk can find things faster. Scan Disk checks your hard disk for errors and fixes them so that your hard disk runs better.

9. Keep your Hard Disk Free
- Your computer gets a harder time looking for a file if your hard disk is full (especially if your hard disk is fragmented) so keep your hard disk as free as possible ^o^.

10. Give your Computer some Rest
-Computers gets tired too you know ;)
