Binary Digit, or Bit
The most basic unit of computer memory is the binary digit, which is more commonly referred to as a bit. A bit can represent only two different values, either true (on) or false (off).

A group of eight bits makes up a byte, but even this unit is tiny, compared with the amount of data that is commonly transferred across the Internet today.

A kilobyte (KB) is 1024 bits long, or can also be thought of as 128 bytes.

A megabyte (MB) is made up of 1024 kilobytes. By now, you should be seeing a pattern emerging here. The now-defunct 3.5 inch floppy-disk, (which was an early form of removable storage), had a maximum storage capacity of approximately 1MB.

Again, a gigabyte (GB) contains 1024 megabytes. You could expect to find 4GB of RAM inside a typical computer being sold these days.

Composed of 1024 gigabytes, a terabyte (TB) is approximately the largest amount of hard drive storage you'd expect to find in a typical desktop computer, although it's becoming more common to see consumer machines with 2TB drives.

Out of interest, I will also mention nibble - which is half a byte, standing at only 4 bits long. Unless you want to pursue a deeper understanding of computer science, then you really don't need to know about nibbles!

It is simple to list that:

  • KiloByte(KB)
  • MegaByte(MB)
  • GigiByte(GB)
  • TeraByte(TB)
Hope I helped.

  • 8 bits = 1 byte
  • 1024 bytes = 1 Kilobyte ( KB )
  • 1024 KB = 1 Megabyte ( MB )
  • 1024 MB = 1 Gigabyte ( GB )
I hope now you understand!
