mainframe computers is essential for some of the largest companies in the world. Every modern mainframe is more than one processor, RAM ranging from a few gigabytes megabytes more score, and disk space and other storage beyond anything microcomputer. The mainframe can control multiple tasks and serve thousands of users every second without stopping.

The main difference between mainframes and other computer systems takes place in the level of processing. Mainframes are also different in terms of bandwidth, organization, reliability, and control. processing of large organizations, banking, healthcare, insurance and telecommunications companies, etc. can be used mainframes critical business data.

In this article, we will discuss the evolution of mainframe computers and parts.

History of mainframe computers

IBM has developed a critical part of mainframe computing, the Auto Sequence Controlled Calculator (ASCC) arithmetic operations, from 1944 to 1950 years of the 1970s, many companies produce large systems: IBM, Burroughs, RCA, NCR, General Electric and Sperry rand, for example. Since then, the System / 390 mainframe, IBM is the only kind of use. It evolved from IBM & # 39; s System / 360 1960

An early mainframe occupied a huge space. New technologies have dramatically reduced the size and cost of the hardware. The current generation of mainframe fits in a small cabinet.

components of modern mainframe

Like a computer, the mainframe has many components of data processing: the operating system, motherboard or motherboard, processor, controller, storage devices and channels.

• Motherboard: The motherboard is a mainframe computer includes a printed circuit board, which allows the CPU, RAM and other hardware components that together with a concept called the "Bus Architecture". The motherboard slot input device interfaces cards and cables for various external devices. If the PC motherboard to use 32- or 64-bit bus, mainframe 128-bit bus. General information with regard to the internal architecture helps the motherboard to connect to other devices and download the data in binary computation.

• Processor: The processor runs on the central processing point mainframe architecture and includes an arithmetic logic unit (ALU) arithmetic calculations. It also works as a controller on the bus architecture and manages traffic and data requests. The high processing power of much larger systems than PCs, so that it can handle huge amounts of data.

• Storage: Entering, retrieving, storing and recording data storage devices. There are many external devices such as hard drives, tape drives, and punch card reader, connecting mainframe terminals and controlled by the CPU. Storage capacity can be hundreds or even thousands of times that of the PC.

controllers • Communication: Communication Controllers allow remote computers to a mainframe. With the help of networking, communications controller LAN or WAN connections to create a variety of devices, perform the transfer of data communication channels, as well as keep track of the user terminals.

• Channels: A "channel" the cables can be connected to the main CPU and the rest of the storage system and make sure that the data is moved in a systematic manner without losing integrity.

Modern mainframes advanced features such as extended service management capabilities, cross-platform integration facilities, etc. and thus capable of critical data center operations. The cost of maintaining a large modern machines is much smaller than the older models.
