Digital computers measure data in terms of bits, which are the smallest unit of information. A bit represents a single binary digit, either a 0 or a 1.
Here's how digital computers use bits to measure data:
- Bytes: A byte is a group of 8 bits. It is the basic unit of data storage in a computer.
- Kilobytes (KB): 1 kilobyte is equal to 1024 bytes.
- Megabytes (MB): 1 megabyte is equal to 1024 kilobytes.
- Gigabytes (GB): 1 gigabyte is equal to 1024 megabytes.
- Terabytes (TB): 1 terabyte is equal to 1024 gigabytes.
These units are used to measure the size of files, the capacity of storage devices, and the amount of memory in a computer.
For example, a typical computer might have 8 GB of RAM and a 1 TB hard drive. This means the computer can access 8 billion bits of information at once and store up to 1 trillion bits of information on its hard drive.
