6. CU (Control Unit):
All the computer’s resources
are managed from the control
unit. The function of control
unit is to coordinate with all
the computer activities. The
control unit contains the
CPU’s instructions for
carrying out commands
7. When the control unit
encounters an instruction
that involves arithmetic or
logic operation, it passes
control to the second
component of the CPU,
the arithmetic/logic unit
(ALU).
The CU and ALU
are in the CPU.
9. Types of Memory:
ROM - Read Only Memory
(contains the basic input output
system or BIOS)
RAM - Random Access
Memory
(user programs and data go
here)
10. The ROM is nonvolatile because it will not
lose its contents when powered down.
RAM plugs into sockets on the motherboard.
11. The CPU can read RAM much faster than it can the hard disk.
