What is means gig bite

It is a form of computer memory

A gigabyte is 109 or 1,000,000,000 bytes. One gigabyte (abbreviated "GB") is equal to 1,000 megabytes and precedes the terabyte unit of measurement. While a gigabyte is technically 1,000,000,000 bytes, in some cases, gigabytes are used synonymously with gibibytes, which contain 1,073,741,824 bytes (1024 x 1,024 x 1,024 bytes). Gigabytes, sometimes abbreviated "gigs," are often used to measure storage capacity. For example, a standard DVD can hold 4.7 gigabytes of data. An SSD might hold 256 GB, and a hard drive may have a storage capacity of 750 GB. Storage devices that hold 1,000 GB of data or more are typically measured in terabytes.
