A bit is defined as: a single basic unit of information, used in connection with computers and electronic communication. All modern computers store and use data in digital form. The smallest unit of storage and measurement is one binary digit, therefore its name.
A byte, pronounced ‘bite’, is the next size up basic unit of measurement for information storage, usually consisting of eight bits. These 8 bits are grouped together to form a byte that is, a total or 8 grouped bits representing one character of data.
Therefore, so far we have two basic units of measuring digital information storage that have different capacities, they are:
• 1 Bit
• 8 Bits equal 1 Byte
