Question 5
(a) In a tabular form, state two differences between random access memory and read only memory.
(b) State four characteristics of windows operating system environment.
(c) List two examples of utility programs.
Observation
- DIFFERENCES BETWEEN RAM AND ROM
S/N |
RANDOM ACCESS MEMORY (RAM) |
READ ONLY MEMORY (ROM) |
1 |
Volatile |
Non-volatile |
2 |
Content of RAM can be read, changed or added |
Content of ROM can only be read but cannot be changed or added to |
3 |
RAM chips are relatively expensive |
ROM chips are relatively less expensive |
4 |
RAM chips are slow |
ROM chips are fast |
5 |
RAM is often installed with large storage |
Storage capacity of ROM installed in a computer is much lesser |
6 |
RAM stores all the applications and data when the computer is running |
ROM usually stores instructions that are required for starting (booting) the computer |
7 |
RAM chips are bigger in size |
ROM chips are smaller in size |
8 |
Processor can directly access the content of RAM |
Content of ROM are usually first transferred to RAM and then accessed by processor. This is done in order to be able to access ROM content at a faster speed |
