Chapter 1 Computer overview and its Basics Solutions
Question - 1 : - What is primary memory ?
Answer - 1 : -
Primary memory : This is the storage section of computer which is used to store data or instructions or both for processing purpose. This is non-volatile in nature.
Question - 2 : - What is RAM ?
Answer - 2 : -
RAM : RAM stands for Random Access Memory.
This is the main memory of computer used to retain user’s instructions and data for processing purpose. This is volatile in nature .
Question - 3 : - What is ROM ?
Answer - 3 : -
ROM : ROM stands for Read Only Memory. ROM applies to semiconductor memory whose contents cannot be altered, once they have been set. So non-volatile in nature.
Question - 4 : - What is PROM ?
Answer - 4 : -
PROM : PROM stands for Programmable Read Only Memory. A control memory in which stored
contents can be altered once after they have been set.
Question - 5 : - What is EPROM ?
Answer - 5 : -
EPROM : EPROM stands for Erasable Programm able Read Only Memory. It can be erased and programmed with a special type of equipment. If it is exposed in ultraviolet light, it allows data to be erased and reprogrammed.
Question - 6 : - What is EEPROM ?
Answer - 6 : -
EEPROM : EEPROM stands for Electrically Erasable Programmable Read Only Memory. This type of ROM can be erased and programmed with the help of electric pulse.
Question - 7 : - Give three examples of both input devices and output devices.
Answer - 7 : -
Input Devices :
Output Devices :
Question - 8 : - Name the components of a computer system.
Answer - 8 : -
The computer system consists of two parts :
Question - 9 : - Explain functional components of a computer system.
Answer - 9 : -
A computer system contains many different objects such’ as a CPU, memory, disks, etc. These all must be connected for the system to function.
Question - 10 : - Explain volatile and non-volatile memory.
Answer - 10 : -
The memory is which data is lost when power is removed is called volatile memory. The memory is which data is not lost when power is removed is called non-volatile memory.
