Mainframe is an industry term for a large computer.
The name comes from the way the machine is build up
All units (processing, communication etc.) were hung into a frame. Thus the main computer is build into a frame, therefore: Mainframe

thirty separate units, plus power supply and forced-air cooling, weighed over thirty tons. It had 19,000 vacuum tubes, 1,500 relays, hundreds of thousands of resistors,
capacitors, and inductors which consumed almost 200 kilowatts of electrical power.

processed each digit serially.
But its much higher design speed permitted it to add two ten-digit numbers at a rate of almost 100,000 additions per second Internally.
It was the first mass-produced computer.
The central complex of the UNIVAC was about the size of a one-car garage: 14 feet by 8 feet by 8.5 feet high.
19 July 2006 19CPU , Gen & Current trends
The vacuum tubes generated an enormous amount of heat, so a high capacity chilled water and blower air conditioning system was required to cool the unit.
The complete system had ◦ 5200 vacuum tubes,◦ weighed 29,000 pounds,◦ and consumed 125 kilowatts of electrical power.

It was the first large-scale commercially available computer system to employ fully automatic floating point arithmetic commands.
It was a large-scale, electronic digital computer used for solving◦ complex scientific, engineering and business
problems ◦ was the first IBM machine to use FORTRAN.
The 704 and the 705 were the first commercial machines with core memories.
19 July 2006 21CPU , Gen & Current trends
Developed primarily to handle business data, it could multiply numbers as large as one
billion at a rate of over 400 per second. The 705 was credited with "Forty thousand or
twenty thousand characters of high-speed magnetic core storage;”
Any one of the characters in magnetic core storage can be located or transferred in 17 millionths of a second;
Any one of these characters was individually addressable.

The IBM 701 Electronic Data Processing Machine was IBM's first commercially available scientific computer and the first IBM machine in which ◦ programs were stored in an internal- addressable
electronic memory.
◦ It was the first of the pioneering line of IBM 700 series mainframe computers, including the 702, 704, 705 and 709.

◦ two tape units (each with two tape drives),◦ a magnetic drum memory unit, ◦ a cathode-ray tube storage unit,◦ an L-shaped arithmetic and control unit with an
operator's panel,◦ a card reader, ◦ a printer,◦ a card punch and three power units. ◦ The 701 could perform more than 16,000 addition or
subtraction operations a second,◦ read 12,500 digits a second from tape, print 180
letters or numbers a second, and output 400 digits a second from punched-cards.

The IBM 1401 is called the Model T of the computer business, because it is the first mass-produced digital, all-transistorized, business computer that was afforded by many businesses worldwide.
The basic 1401 was about 5 feet high and 3 feet across.
It comes with 4,096 characters of memory( 4KB)
The memory is 6-bit (plus 1 parity bit) CORE memory,

made out of little metal donuts strung on a wire mesh at IBM factories.
The 1401 has an optional Storage Expansion Unit which expanded the core storage to an amazing 16K.
The 1401 processing unit can perform 193,300 additions of eight-digit numbers in one minute.
The monthly rental for a 1401 is $2,500 and up, depending on the configuration.
In the mid-1960s, more than 10,000 system were in the market and by 1971 IBM started withdrawing these system .

operating system which occupied about 8K of the 1107's 32K of memory.
The machine was intended to support true multiprogramming:
sharing CPU time among several batch runs.

A mainframe has 1 to 16 CPU's (modern machines more)
Memory ranges from 128 Mb over 8 Gigabyte on line RAM
Its processing power ranges from 80 over 550 Mips
It has often different cabinets for ◦ Storage ◦ I/O ◦ RAM
19 July 2006 32CPU , Gen & Current trends
Separate processes (program) for ◦ task management ◦ program management ◦ job management ◦ serialization ◦ catalogs ◦ inter address space ◦ communication
19 July 2006 33CPU , Gen & Current trends
centralized computing opposite from distributed computing. Meaning all computing takes (physically) place on the mainframe itself: the processor section .
main purpose is to run commercial applications of Fortune 1000 businesses and other large-scale computing purposes.
