Memory
The memory considered this section
divided in two basic types
- Random access memory (RAM)
- Read only memory (ROM)
The RAM can be explained as a device
that temporarily store data. RAM can be read from also written into. The key
feature of the RAM is that when power of the computer is switch off the data in
the ram in the lost (Volatile Memory)
As access to ram is very much faster
than to a permanent storage device, it is an inefficient method to read and
write to permanent storage as it will simply slow the processing down a great
deal.
ROM as implied by term is a type of
memory which can only be read from. This type of memory does not lose its data when
the power off the computer is turned off. The most common ROM in the computer
is the bios (Basic Input Output System) ROM.
The CMOS (Complementary Metal Oxide Semiconductor)
chip is also belongs to volatile memory since it requires power from the battery
to retain the data once the computer is turned off.
