Mainframe Computer

Mainframe Computer

Mainframes are computers. At their core, mainframes are high-performance computers with large amounts of memory and processors that process billions of simple calculations and transactions in real time.

Features of a Mainframe Computer
  • Presence of two processors. ...
  • Multiple input/output (I/O) cards. ...
  • High storage capacity. ...
  • RAS-based performance. ...
  • No interruptions in the functioning. ...
  • Multiple operating systems on the same machine. ...
  • Throughput-driven fault-tolerant computing. ...
  • Clustering technology.

A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.

Introduction to Computer

Image
Computers are electronic devices that are designed to process, store, and retrieve data. They are used for a wide variety of purposes, from personal computing to complex scientific simulations and industrial automation. A computer consists of various hardware components, including a central processing unit (CPU), memory, storage devices, input/output (I/O) devices such as keyboards, mice, and displays, and various other peripherals. Computers communicate with each other over networks, which are interconnected groups of computers that share resources and information. The internet is a global network that connects millions of computers around the world and enables communication and information sharing on an unprecedented scale. The field of computer science is concerned with the study of computers and computational systems, including their design, development, and application. It encompasses many subfields, including artificial intelligence, computer graphics, databases, programming lang...

Computer Generation

Image
 There are five generations of computer:  First generation– 1946 - 1958  Second generation– 1959 - 1964  Third generation– 1965 - 1970  Fourth generation– 1971 - today  Fifth generation– Today to future The First Generation   The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms.  They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions. The Second Generation   Transistors replaced vacuum tubes and ushered in the second generation of computers.  One transistor replaced the equivalent of 40 vacuum tubes.    Allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable.  Still generated a great deal of heat that can damage the computer. The Third Generation  The development of the integrated circuit was ...
