Because RAM is volatile and ROM cannot be changed, there must be places
to store data and programs outside of the computer’s main memory. Such
places are called secondary storage devices.
3.
ALU- performs arithmetic/logic operations
4.
Control Unit- controls the various parts of a computer hardware
5.
Memory- stores both data and program
6.
Magnetic tape is a cheap medium for storing great quantities of data.
However, data items cannot be directly addressed on tape. To reach a data
object, all information recorded before the one you want must be read and
discarded.
7.
The stored program concept means that data and instructions are both
logically the same and can both be stored in memory. The von Neumann
architecture is built around this principle. It is important because the human
does not have to execute instruction from without the machine. Instructions
can be stored in memory and executed in sequence referencing the data
values it needs on which to operate.
