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.
