peopleware, hardware and software.. plus computer types part 1

Peopleware are used to describe us, because peopleware is define as anyone who uses computer.


Then we have the hardware.

I must say that I have the advantage for this topic, for I already took up this lesson back then to "Introduction to Information Technology". 


With these session, I have learned the solid parts of a computer, which are divided into six categories. These are named as the central processing unit, primary storage,input devices, output devices, secondary storage and lastly the communication devices.

The Central Processing Unit is commonly mistaken as the system unit. But in fact, it is not the large metal case on a computer  set but rather a chip. It is the "brain" of a computer. Without it, there will be no computer, for it is the one that controls and process the task of a computer.
Also known as the microprocessor.

Central Processing Unit is consist of control unit, the arithmetic-logic and the primary storage.

Control Unit reads, interprets, and carries instructions. It does not change nor create a new data but rather directs it to the other components of the computer system. It also controls the input and output devices. It may only process one instruction at a time but it can execute instructions quickly(millions per second).

Arithmetic-Logic Unit, performs arithmetic and logic operations.

We also have the primary storage. It is also known as the internal storage, under the CPU. It temporarily stores the data on a computer. Examples of it are:

1. Registers 

2. Random Access Memory (RAM)

3. Read Only Memory (ROM) 

4. Cache Memory 

5. Flash Memory
