The first mainframes were large enough to fill an entire room. The mainframes today created by IBM are about the size of your household refrigerator.

They are large in size, processes of power and high level of reliability , amount of storage , mainframe have ability to run multiple operating system. they are designed to handle very high volume input and output and a single mainframe can replace dozens or even hundreds of smaller severs.
There are four types in the classifications of the computer by size are Supercomputer, Mainframe computer, Minicomputer, and Micro Computer.
Mainframes have a history spanning over 60 years: 1950s: Early large-scale computers such as IBM's 701 introduced centralized computing for governments and businesses. 1960s: IBM launched the System/360 (1964), creating a standardized mainframe family that could support different business workloads. 1970s–80s: Mainframes became central to banking, airlines, insurance, government, and large enterprises. Technologies such as CICS, DB2, and COBOL became widely used. 1990s: Mainframes evolved with stronger networking, virtualization, and enterprise database capabilities, while continuing to run critical legacy applications. 2000s–2010s: IBM's zSeries/System z platforms integrated Linux, virtualization, improved security, and web technologies. Today: Modern IBM Z systems continue to process high-volume, mission-critical workloads while integrating with cloud, APIs, DevOps, analytics, and AI. In short: Mainframes evolved from large centralized computers into highly secure, resilient enterprise platforms that still power critical digital services worldwide.
A mainframe computer cost round about 2-3 thousand dollars. Mainframe computers are built to the specifications and to suit the requirements of the end user. They may cost anywhere between several thousand and several million dollars.
There are several different sizes of mainframes. The typical size for a mainframe is an estimated 2,000 to 10,000 square feet. Some can be as large as 20,000 square feet.
Yes, Linux can be used on a mainframe.
Mainframe - comics - was created in 1999.
Mainframe computers were developed in the early 1950's when computers were made that size. It means the cabinet more than the contents as early ones had the CPU (Central Processing Unit) in a separate cabinet.
