IBM produced their first mainframe computer in 1952. Between 1952 and the late 1970's the term "mainframe computer" was automatically linked with IBM because they had the largest share of the computer market.

Historically (i.e. going back to the 1970's) there have been many operating systems for the mainframe. At that time there were several companies (IBM, ICL, Siemens, Fujitsu, GEC, etc) making mainframes and each had it's own operating system. Today there is only one manufacturer still in this very lucrative market - IBM. IBM has had several mainframe operating systems - today they have three still in use - the main and most powerful one is z/OS (often referred to as MVS), the other two are z/VM and VSE/E.

These days it is almost impossible to find courses at universities and colleges that specialize in mainframe courses - the demand is not there anymore.
Therefore, if you want to learn about mainframes you will probably have to take courses from the mainframe vendors, such as Unisys or IBM. Check their course catalog on their web sites for places and times on various courses.

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.

There are mainframe computers, mini computers and micro computers. Mainframes are large scale computers, (search IBM System/360) mini computer are smaller, a lot smaller than mainframes (search IBM AS/300) and minis are what's on your desktop like a DELL, HP, Sony, etc.

IBM
System/360 (S/360) was a mainframe computer system family first announced by IBM on April 7, 1964, and sold between 1964 and 1978. It was the first family of computers designed to cover the complete range of applications, from small to large, both commercial and scientific. The design made a clear distinction between architecture and implementation, allowing IBM to release a suite of compatible designs at different prices - See more at: http://www.chacha.com/question/what-is-the-significance-of-the-ibm-360-machine#sthash.mrtP0FnR.dpuf

thousands of dollars while a mainframe often has the components to build many computers with multiple processors and hard drives and even sometimes multiple of these linked together to complete the system. if your not a really large buissnes like IBM or such chances are you can live well with a home server from Microsoft or their small buissnes server.

It depends on the target platform. If you want to use MF COBOL on the mainframe then the answer is none, MF supports the mainframe as a target by using MF EEE. You write and unit test the code on the PC and then send the source off to the mainframe for compilation and final testing.

The first one I know of hit IBM in 1984 called christmas-A because CHRISTMAS was truncated to CHRISTMA due to mainframe limitations at the time. It was created by a German student in a college that IBM sponsored. What it did was lock out your keyboard (on you dumb terminal) and send all your email history to everyone in your email log with the virus as a tag-along. This filled up the shadow servers worldwide really quick and nailed IBM for 2-3 weeks. IBM never released the name of the student, but did hire him.

In terms of an IBM mainframe, a Channel is the electronic circuitry and wiring cables that allows for the connection of peripheral equipment. Such devices as tape drives, DASD (hard drives), card readers, etc, are attached to the Mainframe via Channels. Data moves down the channel as electronic signals. The position on the channel establishes its identifying Address.

It is not impossible. If the original algorithm was written in a portable fashion it should be portable. If not, then it won't be. Its as simple as that.
One of the factors of portability with an IBM MainFrame is the endian-ness of the integers. The MainFrame is big-endian, while most other computers are little-endian. This, however, should not be a problem unless the original algorithm was incorrectly written, i.e. being dependent on internal bit representation.
You don't specify the algorithm. It would be helpful if you could post it here, and we can analyze it...

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'

Sperry built the first mainframe computer about 1950, soon followed by IBM. In the beginning it was envisioned that only about six computers could be usefully employed, for example, by the Bureau of the Census, the Internal Revenue Service, the Department of Defense.

The only real high end operating system runs on the IBM mainframe system now named IBM system Z. The actual system software is called Z/OS. It is used in banks and large corporations and has been around in various incarnations since the 1960's. The IBM system Z also runs Linux.
Also high end are:
The IBM power platform runs the IBM I system (a descendant of the IBM system/38 and AS/400), a corporate branch workhorse. It also run IBM AIX (a version of original unix) as well as Linux.
The HP OpenVMS system, known for its security features, stability and long uptime runs on the Intel Itanium platform which also runs a HP-UX (a version of unix) and Linux.
