• Mainframe computers are large (2,000 to 10,000 square feet) and powerful
machines that are used primarily in data centers for large organizations.
They are typically found in a dedicated server room and feature multiple
central processing units (CPUs), which are connected to each other and to a
variety of other computers and smart devices to form a larger computing
system. Mainframe computers can access by multiple users simultaneously.
They were invented in the 1950s and are capable of processing massive
amounts of data (up to 30 billion transactions per day) quickly and
accurately. Mainframe computers have been upgraded to levels of security,
scalability, and reliability, making them ideal for critical operations such as
banking, government, or insurance. Mainframe computers are also used for
air traffic control, satellite tracking, and military defense systems.
