The memory sizes in mainframe computers and advanced technology micro computer are expressed as

Bytes
Kilobytes
Bits
Megabytes E. None of these

The correct answer is: D. Megabytes

A byte is a unit of digital information that most commonly consists of eight bits. A bit is the most basic unit of information in computing and is represented by a 0 or a 1. A kilobyte is equal to 1024 bytes, a megabyte is equal to 1024 kilobytes, and a gigabyte is equal to 1024 megabytes.

Mainframe computers and advanced technology microcomputers typically have memory sizes that are measured in megabytes or gigabytes. This is because these computers need to be able to store large amounts of data and programs.

Here is a brief explanation of each option:

  • A. Bytes are the most basic unit of information in computing. They are represented by a 0 or a 1.
  • B. Kilobytes are equal to 1024 bytes. They are often used to measure the size of files and programs.
  • C. Bits are the smallest unit of information in computing. They are represented by a 0 or a 1.
  • E. None of these is not a correct answer.
