Classification of Computers by John Gibb
Computers are available in different shapes, sizes and weights, due to these different shapes and sizes they perform different sorts of jobs from one another. They can also be classified in different ways. All the computers are designed by the qualified computer architectures that design these... Mainframes Another giant in computers after the super computer is Mainframe, which can also process millions of instruction per second and capable of accessing billions of data. ... Minicomputer This computer is next in he line but less offers less than mainframe in work and performance.

History of the Computer: Handshaking, Part 1 of 2 by Tony Stockill
There is still information to be transferred to the I/O unit from the printer, for example a request for the next line of print, or an error message. So we use an OUTPUT cable and an INPUT cable. Apart from this, the printer is an Output Device. (We are talking here about the System Line... We observe a convention here, that data movement FROM the mainframe is considered to be OUTPUT, while data TO the mainframe is considered input. ... When the program running on the mainframe wants to print something on the line printer, it sets up certain information in registers, via the Operating...

Virtual PC - Slicker Than Oil by Don Watkins
When I was younger and worked on mainframes I was always working with pretty mundane stuff; batch processing for the most part with what little online work being done with smaller computers (Buker-Ramo if you must know) with the mainframes running DOS/VSE. ... But my experience was from afar, I left the mainframe world and never got to work with it full time. ... You can set up a virtual machine just like it's a real computer with it's own IP address, installed programs, anything you can thing of.

Desktop Computers by Marcus Peterson
A desktop computer is a computer that is built so that it can be used in a home or office setting. It is distinguished from a laptop or a much larger mainframe computer. The typical desktop computer will consist of three devices – namely, an input device, a processing device and an output device. ... Your desktop computer or personal computer (PC) should have a good data storage capacity, and the chip running the computer should be a good one that can do billions of calculations per second and give you the best results.

Data Mining vs Screen-Scraping by Todd Wilson
Data mining isn’t screen-scraping. I know that some people in the room may disagree with that statement, but they’re actually two almost completely different concepts. In a nutshell, you might state it this way: screen-scraping allows you to get information, where data mining allows you to... The term "screen-scraping" comes from the old mainframe terminal days where people worked on computers with green and black screens containing only text. ... That is, computer programs can "crawl" or "spider" through web sites, pulling out data.

With the widespread use of computers today in all there many forms, it is hard to remember that computers are a recent event. A look back through time shows they are a recent event. The past of computers is actually the history of man's attempts to understand and manipulate mathematics. ... In 1975, an IBM mainframe computer capable of 10 million instructions per second would have cost around 10 million dollars. ... Perhaps this was one of the most significant developments of all in the move to the personal computer.

Data Entry Guide - Guidelines for Data Entry by Sardool Sikandar
Data entry is used to convert data into information. Data entry is also known as data processing that is generally programmed on a mainframe, minicomputer, microcomputer or personal computer. Data processing systems are required for data entry work and these systems manipulate raw data into... Data entry is very useful in large organizations and established businesses. ... The control of hardware by a device driver manipulating ASIC or FPGA registers is not observed as a part of data processing.
