USING A COMPUTER

1.9. Computer memory

Units of measurement:
A bit is the smallest unit of information in a computer, encoded by a single two-state element (0 or 1). A byte (B) is a unit of computer memory equal to 8 bits. This is sufficient to encode one character of text.
1 byte is 8 bits.
1 Kilobyte (Kb) - 1024 bytes.
1 Megabyte (Mb) - 1024 Kb
1 Gigabyte (Gb) - 1024 Mb
1 Terabyte (Tb) - 1024 Gb, etc.
Computer memory is divided into external and internal memory.
Internal memory is placed on the motherboard.
The computer handles information - more specifically, data that is stored on the computer's hard disk drive (HDD). When we need to move data from one computer to another, we save it on other media - flash drives, portable drives.
