Final answer:
A logical group of 8 bits is known as a byte. Kilobyte, megabyte, and gigabyte are larger units of computer storage, with a megabyte being about one million bytes.
Step-by-step explanation:
A logical group of 8 bits is known as a byte. When we talk about computer memory and data storage, the term byte is very common. Computer storage space is measured in bytes and various multiples thereof. Here's a quick run-through of larger units:
- A kilobyte (KB) is technically 1,024 bytes, but often approximated as 1,000 bytes for simplicity.
- A megabyte (MB) is 1,024 kilobytes, which indeed equals about 1 million bytes, hence the 'mega' prefix indicating a million.
- A gigabyte (GB) is 1,024 megabytes, and moving up the scale, a terabyte (TB) is 1,024 gigabytes.
To answer the student's question directly: a logical group of 8 bits is also known as a byte (Option 1).
