Objectives: Binary and Data Representation

Define the term 'bit'.

• A bit is the smallest unit of data in a computer, representing a single binary value of 0 or 1.

• A bit is the greatest unit of data in a computer, representing a single binary value of 0 or 1.

• A bit is the longest unit of data in a computer, representing denary values.

• A bit is a programming language in a computer, representing denary values.

Define the term 'nibble'.

• A nibble is a group of four bits.

• A nibble is a group of eight bits.

• A nibble is a group of two bits.

• A nibble is a group of sixteen bits.

Define the term 'byte'.

• A byte is a group of eight bits.

• A byte is a group of four bits.

• A byte is a single bit.

• A byte is a group of sixteen bits.

Define the term 'kibibyte'.

• A kibibyte is 1024 bytes.

• A kibibyte is 1000 bytes.

• A kibibyte is 512 bytes.

• A kibibyte is 2048 bytes.

Define the term 'mebibyte'.

• A mebibyte is 1024 kibibytes.

• A mebibyte is 1000 kilobytes.

• A mebibyte is 1024 megabytes.

Define the term 'gibibyte'.

• A gibibyte is 1024 mebibytes.

• A gibibyte is 1000 megabytes.

• A gibibyte is 512 kilobytes.

• A gibibyte is 2048 bytes.

Define the term 'tebibyte'.

• A tebibyte is 1024 gibibytes.

• A tebibyte is 1000 gigabytes.

• A tebibyte is 1024 megabytes.

Define the term 'pebibyte'.

• A pebibyte is 1024 tebibytes.

• A pebibyte is 1000 terabytes.

• A pebibyte is 1024 gigabytes.

• A pebibyte is 1000 megabytes.

Define the term 'exbibyte'.

• An exbibyte is 1024 pebibytes.

• An exbibyte is 1000 petabytes.

• An exbibyte is 1024 terabytes.

• An exbibyte is 1000 gigabytes.

Computers use binary to represent all forms of data because:

• Binary is simple for computers to process using electrical signals.

• Binary allows computers to understand human language directly.

• Binary is the only numbering system that exists.

• Binary makes computers slower but more accurate.
