Computer is an electronic device
who are already familiar among children
children to adults, of course, with
level of understanding and use of the
different.
said to be a human architecture.
Physical form can not be called a human life
normal. To be called a man who lives it is necessary
the existence of spirit or soul, as a form of non-physical. Non-physical form
others like common thoughts and feelings that will
employ physical parts to the application or activity
in accordance with the will of mind and feeling
own.
Likewise, the computer also has a physical part
Hardware-called non-physical and so-called
Software / Computer Program.
Computer Architecture
Analogous to humans, computers also have a part-this part
which have different functions. The composition and location
relationship between the parts to form the body computer
referred to as computer architecture. Or in other words
computer architecture is the organization of part-any part of
a functional computer.
In principle, a computer system consists of 3 parts
main, namely:
1. CPU
2. Memory, the memory comprising program and data memory, and
3. Device Input / Output
This new computer system will work if adaprogra m
computer that contains instructions that instruct the CPU.
CPU (Central processing Unit)
CPU is a functional part
the principal of a system
computer, it can be said that
CPU is the brain of a
computer. In the CPU is all
computer work done.
Things that need to be done CPU
are:
1. Read, encode and
execute instructions
program
2. Sending data to and from memory, as well as from and to the input / output.
3. Respond to interruptions from the outside.
provides clock and signal
control to the system.
In doing the things above, clear the CPU needs to store data
for a while. CPUs need to remember the location of the instruction
last so that the CPU will be able to take the next instruction.
CPU needs to store instructions and data temporarily
when the instruction is dieksekusi.Dengan other words, the CPU
require a small internal memory called registers.
Arithmetic and Logic Unit (ALU) function-forming operations
arithmetic and logic operations on the data register stores
preliminary data and results of operations of the ALU.
Control unit produces a signal, which will control the operation
ALU, and the transfer of data to the ALU.
