Representation of Memory

The memory is represented with characters.

Let us read about the various terms related to memory.

Byte

A byte is the smallest group of information that a computer can process in one chunk
or bites. The bits in a byte are processed together and more importantly for us. The
byte is presented to us in a form that we can understand. Each byte can be encoded
to correspond to a digit, a letter of the alphabet, a punctuation character or other

symbol.

Kilobyte
1024 characters are equal to one kilobyte.

Megabyte 1,048,576 characters are equal to one megabyte.

Gigabyte 1,073,741,824 characters are equal to one gigabyte.

Terabyte 1,099,511,627,776 characters are equal to one terabyte.

Computer memory is analogous to your brain. It contains all the vital information

(data), along with instructions needed to process that very information! Without a
computer memory, it would nearly be impossible for a computer to carry out even the
simplest of all tasks such as ‘Copy/Cut and Paste’.

8 Memory is required in computer to store data and instructions.
8 The bits in a byte are processed together.

8 There are two types of primary memory—RAM and ROM.
8 1024 characters are equal to one kilobyte.

8 SRAM is used primarily to create CPU’s speed-sensitive cache.
8 CD-ROM is also known as a WORM-Write Once Read Many Medium.
