In this article, we are providing the gist of Basic Computer Knowledge Terms:

Memory Units:

  • bit is represented by b
  • Byte is represented by B
  • mega bits per sec is represented by Mbps
  • mega Bytes per sec is represented by MBps
  • 4 bit = 1 nibble
  • 8 bit = 1 byte
  • 1024 B = 1 KB (Kilo Byte)
  • 1024 KB = 1 MB (Mega Byte)
  • 1024 MB = 1 GB (Giga Byte)
  • 1024 GB = 1 TB (Tera Byte)
  • 1024 TB = 1 PB (Peta Byte)
  • 1024 PB = 1 XB (Exa Byte)
  • 1024 XB = 1 ZB (Zeta Byte)
  • 1024 ZB = 1 YB (Yota Byte)

Flowchart:          bit < Byte < KB < MB < GB < TB < PB < XB < ZB < YB
