Mainframes (often colloquially referred to as big iron) are large and "expensive" computers used mainly by government institutions and large companies for mission critical applications, typically bulk data processing such as censuses, industry/consumer statistics, ERP, and financial transaction processing.
The word mainframe refers mostly to the computer's metal housing(s), not the hardware inside that housing(s); or the use the computer is put to. Almost all computers prior to the middle 1960s were mainframes, until monolithic silicon integrated circuits allowed the circuitry of the computer to be miniaturized enough to allow the use of significantly smaller housings and the introduction of minicomputers. In the early 1970s, LSI and VLSI microprocessors allowed further miniaturization and the use of even smaller housings and the introduction of microcomputers.
Mainframe computers are giant computers designed to process and store massive amounts of data. Mainframe computers take up whole rooms and usually have their own dedicated air conditioning systems due to the amount of heat they generate.
Main frames are BIG computers:
Since 1993, the fastest supercomputers have been ranked on the TOP500 list according to their LINPACK benchmark results. The list does not claim to be unbiased or definitive, but it is a widely cited current definition of the "fastest" supercomputer available at any given time.

Transfer file from and to mainframe using FTP You can use FTP dos command to transfer files from and to mainframe Step1: Start --> Run --> Command Step2: Enter the following command FTP XX.XXX.XX.XXX Where XX.XXX.XX.XXX is the ip address of mainframe Step3: When you are prompted for user name and password, provide your mainframe id and mainframe password Step4: To download the file from mainframe to PC Get 'FIIE.ON.MAINFRAME' D:\MYFILES\TEST.TXT To Upload the file to mainframe from PC PUT D:\MYFILES\TEST.TXT 'FILE.ON.MAINFRAM'
The slowest is mainframe then palmtop and the fastest is desktop. Good luck! =)
Control-m is a tool for scheduling and monitoring jobs in mainframe technology
Centalized database organizes all of an organization data , it is like a mainframe computer. Like in any company or firm all the data is integrated in to a single system.
On a mainframe, device-dependent function is assigned to an I/O control unit.

IBM system 3 and AS-400 are some examples of minicomputers.
Mainframe operating systems are used to process large amounts of information for businesses and organizations. Examples include IBM OS/360, ICL 1900 Series, and HP-UX.
