A bit is the fundamental building block of data. A bit has 2 states. A bit can take a value of 0 or 1. One can also think of a bit as a switch. It has an off position (0) and an on position (1). When 8 of these bits are placed together, they result in what is known as a Byte. For example, 00000001 is a byte. As well as the number 10110001. Any combination of 8 bits is always referred to as a Byte. The significance of all of this is paramount.
Although the mathematics and computer science behind binary systems is beyond the scope of this blog; each Byte can be translated to a number. And each number can indicate to either hardware or software to do something. For example, the first Byte that was given as an example, 00000001 could prompt a car engine to start, or a light bulb in a room to turn on. However, the second byte string given 10110001 could tell a software application to display a picture of a flower on the screen. For ALL computer information that is retrieved, sent, updated and deleted is done so by the manipulation of Bits and Bytes.
