Memory-Mobo-Hard/Software

The memory is divided into large number of small parts called ____. Each ____ has a unique address, which varies from zero to memory size minus one. For example, if the computer has 64k words, then this memory unit has 64 * 1024 = 65536 memory locations.

(a)  

It is a very high speed semiconductor memory which can speed up the CPU. It acts as a buffer between the CPU and the main memory.

• registers

• ROM

• RAM

• cache memory

It is the working memory of the computer.

• registers

• ROM

• RAM

• cache memory

It is the memory from which we can only read but cannot write on it. This type of memory is non-volatile.

• registers

• ROM

• RAM

• secondary memory

It is slower than the main memory. These are used for storing data/information permanently.

• registers

• secondary memory

• RAM

• cache memory

Cache memory is faster than main memory.

• TRUE

• FALSE

Primary memory holds only those data and instructions on which the computer is currently working. It has a limited capacity and data is lost when power is switched off.

• TRUE

• FALSE

This type of RAM need not be refreshed on a regular basis. It is expensive and has very fast access.

• SRAM

• DRAM

• Cache

• Registers

EEPROM is programmed and erased electrically. It can be erased and reprogrammed about ten thousand times.

• EPROM

• EEPROM

• PROM

• MROM

It is read-only memory that can be modified only once by a user.
