Memory
The storing of data in
the form of binary words is called as memory.
Explain : Data type memory and storage type memory
Data type memory
It is used to store data.
Storage type memory
It is used to store programs.
Which is the storage elements used in the memory?
Storage element in the
memory
Capacitor in the
semiconductor memory
Magnetic domain in the
magnetic memory
Flip flops
Write the full form of MBM.
The
MBM stands for magnetic bubble memory.
Describe the difference between main and peripheral memory.
Main memory
It is an internal part of
the computer.
It is very fast.
It is used generally for
program memory.
The semiconductor
memories are suitable for main memory because of its higher speed.
The semiconductor
memories are constructed using semiconductor ICs.
Peripheral memory
It is add on memory which
consists of large storage capacity.
It is much slower than
the main memory.
It is generally used for
store large amount of data.
Magnetic tape and magnetic
disk are example of peripheral memories.
It is also called as
auxiliary memory.
Define : Address, word, cell and capacity of memory
Address
The storage location of
the binary information or bits is called as address.
Word
The fundamental group of
bits is called as word.
Cell
A storage element is
called as cell.
Capacity of memory
The total number of bits
or bytes or words that can be stored by memory is called as capacity of memory.
Explain the term : Volatile memory and Non – volatile memory
Volatile memory
It is a memory whose data
is lost when the power supply is cut off.
Non – volatile memory
It is a memory whose data
does not lost when the power supply is cut off.
How many bits does a byte consist of?
One byte means 8 bit
What do you mean by 4K?
The size of the memory is
represented by K (It is equal to 210 = 1024 words). Therefore the
memory of size 212 (4096 words) is equal to 4K.
What do you mean by ‘mass storage’?
Mass storage
It is memory that is
external to main computer.
What do you mean by reading and writing of data?
Reading and writing data
The process of storing
data in the memory is called as writing in the memory. The process of
retrieving data from the memory is called as reading in the memory.
Describe the importance of read / write input in the memory.
The read operation takes
place when read / write is equal to unity whereas the write operation takes
place when read / write is equal to zero.
What is meaning of 64 × 4 memory?
The word size of the
memory is 4 bits and it stores 64 words.
How many address line does the 4K × 16 memory consists of?
There are 12 address lines requires for memory
4K × 16 ( The 4K is equal to 4 × 1024 = 4096 words = 212 ).
Which type of memory is used for permanent storage of programs?
ROM ( Random access memory)
