What does MB KB and GB mean?

Answer 1

MB, KB and GB are all shortened names measuring the amount of memory or disk space that is used by a computer. KB stands for kilobyte, which is 1000 bytes. MB stands for megabyte, which is 1000 kilobytes. GB stands for gigabtye, which is 1000 megabytes. It should be noted that computer operating systems and computer hardware manufacturers measure these sizes differently. Since computers are built on binary operations, they specify sizes based on the power of two. For a computer, a kilobyte is 1024 bytes, a megabyte is 1024 kilobytes and a gigabyte is 1024 megabytes. So, if you purchase a 500 gigabyte hard drive (based on 1 kilobyte = 1000 bytes), the hard drive manufacturer will measure that as 500,000,000,000 bytes. When the computer recognizes the hard drive, it will tell you that the hard drive is 465.66 gigabytes (base on 1 kilobyte = 1024 bytes). It should be noted that although the standards bodies prefer to measure a "1024" kilobyte as a "kibibyte" and so forth, the terms "kibibyte", "mibibyte" and "gibibyte" are not commonly used.

Answer 2

These are the units for measuring the digital information you will download or store on your phone/computer ect. Kb stands for kilobyte and just over 1000Kb make up one Mb. MB stands for megabyte and is made up of approximately 1000 bytes. About 1000 megabytes makes up one GB - as in gigabyte.
