5 main component of a computer..

hye every one.. it’s been a while rite.. I’m so sorry because I’m too busy lately with the university registration. After all,  I have something to share with you. Here, the very basic and the most simple things in computing. But, it’ll help a lot to recognize which is the most important for anyone who is plan to buy computer partly.

After doing some research and reading I found that there are 5 most important component in a computer system which three of them are vital. Let me list down all five component before we go through it one by one.

1. Motherboard (MOBO) / Mainboard

2. Memory

3. Power Supply Unit (PSU)

4. Hard disk (HDD)

5. Peripherals.

Let’s take a look of the first component which is motherboard or simply called MOBO. Most of us call it a heart/brain of a computer which help do all the process. Actually I combining processor(cpu) with MOBO and call it one component since processor sit directly on MOBO. You can find it two different things later. A matter of simplification, just take it as one. The cpu will do all the needed process. cpu contain 3 component which are control unit (CU), Arithmetic Logic Unit (ALU) and register. Beside that, MOBO consist of Basic input/output system (BIOS). BIOS is the initial software before load the operating system (OS). Without BIOS, the computer won’t know what to do.(we will discuss bout BIOS later on). MOBO is also important for data send/receive purpose. MOBO consists of a web of busses from/to storage or else for the data send/receive. MOBO also consists of HUB which work as a house to many other peripheral devices like mouse, printer and monitor.

The second and vital component of a computer is memory. There’s a lot of memory to be covered, but let’s focus on this one, the most important memory called Random Access Memory (RAM). RAM is one form of data storage and normally recognized as a primary storage. RAM temporarily stores files & information that it can pull at random when running program or applications. Together with CPU, RAM determines the computer speeds. All data and information stored in RAM will be deleted when the power off. Read the rest of this entry »

But if you’re transferring small size of files, than USB Bluetooth would really help.

PC buying guide

Buying PC is not really as simple as one might think. To get a good bargain of PC with affordable price as possible, some factors need to be taken into accounts. The most important factors that I always consider are prices, places to buy, PC usage and performance, the warranty period, and either to buy a new set or second hand PC.

So, lets go into each of the factor with more detail.

Price vs Distance

Money is a very important aspect in buying PC especially for a average person. Some people like to buy PC parts or completed PC at Lowyat (near Imbi Plaza, KL) since they can get the best price for PC parts there. For some people, they like to buy PC parts online whether from auction websites or forums because they can get PC parts at cheaper prices compare to retail one. Read the rest of this entry »

So how about you? Already have your own personal computer or still confuse which one is more appropriate. If so, below comparison should help you get the ideas to know which one suit you best. Laptop or desktop.

Dell computer

Who do not know Dell, a big name in computer related business. Talk about Dell, he actually start his business while in college. At the time, computer set is still new to society. Not many people who can install computer by their own. Looking at this chance, Dell start his business at small scale. He buy computer parts at cheap prices and then he installed all of the parts into complete PC by himself. That’s just the start. Now Dell has their own model of computers and parts (such as Dimension Memory and Dimension RAM).

I believe a lot people should find Dell price is among the best price available in buying PC. Two years ago, my friend bought himself a set of Dell computer. The price is affordable and the spec is really awesome. A lot of big companies also preferred Dell computer as their server. This is nothing to be surprised since Dell computer is said to be top notch in reliability and performance.

Despite a powerful computer, user still need to know that computer memory (RAM) plays a major role in a delivering computer performance and efficiency. Dimension Memory Upgrade might be a good choice to find suitable ram especially ram that related to server computer. Not only for Dell, but for other platforms too. No matter how powerful a computer is, the performance will be bad if the memory size and speed isn’t suit to the processor speed.

How to activate MMS and 3G

What is MMS

MMS stands for ‘multimedia messaging service’. In contrast to SMS (short message service), phone user can send longer text message than SMS. Besides that, media such as audio, video and images can embedded in the message too.

Nowadays, there is new style of blogging called micro blogging or live blogging. The main idea of live blogging is to send MMS (picture and text) to Flickr, and then Flickr website will handle the MMS message by automatically creating a blog post at your website based on the MMS. This should save you a lot of time in transferring picture. It is not a dream anymore to blog anywhere by using live blogging, even at a place with no internet connection.

What is 3G

3G is like GPRS with more speed. You can see the details here.

Larger computer memory doesn’t mean faster

I have a friend who is quite rich. He likes to mod his pc and last week he just added another 2GB of computer ram into his motherboard making them 4GB total. He thinks that more speed means faster performance and that’s only half true.

What is the function of computer ram?

When we open a program, our cpu will use some memory that is what we called memory usage. You can view your memory usage by going to task manager (ctrl + alt + del).

For me, I have 1GB of ram and only use xp. For my maximum usage, it only take around 750MB from my memory. So 250MB still free. So why do I need to bother to add my computer ram for larger memory?

Then why my computer shows slow performance?

I think you all need to understand that larger memory doesn’t mean faster performance however when your memory is not enough, let say you have 512MB memory but you use 650MB… from where the 138MB come from?
