    A computer is a machine that can be programmed to accept data (input), process it into useful information (output), and store it away (in a secondary storage device) for safekeeping or later reuse. The processing of input to output is directed by the software but performed by the hardware.   Vintage Computer Federation () owns a Univac B mainframe circa We powered up its paper tape input/output console and .

    Accessory PTP-1 is a high speed, paper tape punch unit for the G Computer. The PTP-1 punches 5-channel tape at a rate of 60 characters per second under computer control. Tape punched by this unit may be read by the computer's built-in photo-electric reader or . Question: A paper tape reader used as an input device to a computer has five rows of holes as shown below. A hole punched in the tape indicates a logic 1 and no hole indicates a logic 0.

    One pair of Input/Output channels is provided with the computer. This pair of I/O channels provides six parallel lines which are employed by the Typewriter Unit. The transfer rate of input or output data over a given channel is determined by the program, and the speed of the paper tape reader and typewriter. output. There is also available a range of alternative input/output equipment for use in Data Processing Systems. INPUT: Whilst the normal input is one or two paper tape channels (read at characters per second), equipment for reading such tape at higher speeds can be supplied. OUTPUT: Punched paper tape output at 50 characters per second is.

Remember, these are independent channel stereo outputs. To input the complete stereo signal, you need two available mono line-level inputs on an interface. Normally, a pair of RCA to 1/4-inch TS cables are used and connected to (2) 1/4-inch line inputs.

Do not connect the tape output lines to an XLR mic-level input. 01 is usually the high-speed paper tape reader. 02 is the high-speed paper tape punch.

03 is the console keyboard (and any associated low-speed paper tape reader). 04 is the console printer (and any associated low-speed paper tape punch). Instructions for device 0 affect the processor as a per: Digital Equipment Corporation.

Punched tape or perforated paper tape is a form of data storage that consists of a long strip of paper in which holes are punched. Now effectively obsolete, it was widely used during much of the 20th century for teleprinter communication, for input to computers of the s and s, and later as a storage medium for minicomputers and CNC machine tools.

Paper tape input and teleprinter output at 6 2/3 characters per second. valves, 12 kW power consumption, occupied a room 5m by 4m. "Operating system" occupied 31 words of read-only memory. Early use to solve problems in meteorology, genetics and X-ray crystallography.

First book on programming by Wilkes, Wheeler and Gill published in In computing, input/output refers to the communication between aninformation processing system (such as a computer), and the outside world.

Inputs are the signals or data received by the system, and outputs are the signals or data sent from it. Examples. These examples of output devices also include input/output devices.

These features include: high speed card punching and reading, magnetic tape input and output, high speed printing, stored program, and arithmetic and logical ability. The elements of the basic system are the Processing Unit, Card Read-Punch, and Printer. Examples of sequential access block devcies include magnetic tape drives and high speed paper tape readers.

input Input devices are devices that bring information into a computer. Pure input devices include such things as punched card readers, paper tape readers, keyboards, mice, drawing tablets, touchpads, trackballs, and game controllers.

FAST, FLEXIBLE INPUT- OUTPUT: I/O operations are con- trolled through a multi-level priority interrupt system. Data transfers take place on A, B, and C channels.

Normally, A and B channels are NTDS compatible and allow bit parallel word transfers at 43, words/sec input, 33, words/sec output.

The architecture has a simple programmed I/O bus, plus a DMA channel. The programmed I/O bus typically runs low to medium-speed peripherals, such as printers, teletypes, paper tape punches and readers, while DMA is used for cathode ray tube screens with a light pen, analog-to-digital converters, digital-to-analog converters, tape drives, disk drives.

Now building a For those with high speed connections, input/output Input/Output (I/O) instructions are used to input data from peripherals, output data to peripherals, or read/write input/output controls.

Early computers used special hardware to handle I/O devices. The trend in modern computers is to map I/O devices in memory, allowing the. Even in the s I used a very similar 'teletype' at my High School to connect via a baud 'acoustic coupler' (Phone in a box!) to the Town Hall computer.

A punched card or punch card is a piece of stiff paper that can be used to contain digital data represented by the presence or absence of holes in predefined positions.

Digital data can be used for data processing applications or used to directly control automated machinery. Punched cards were widely used through much of the 20th century in the data processing industry, where specialized and.

Input-output is via high-speed paper tape reader and punch, direct card reader and punch, and Uniservo magnetic tape units, which may be connected to peripheral punched card readers and punches and a high-speed printer.

In addition, information may be recorded on magnetic tape directly from keyboards by the use of Unitypers. functional computer, known as the Harvard Mark I. The machine, like Babbage’s, was huge: more than 50 feet (15 metres) long, weighing five tons, and consisting of aboutseparate parts, it was mostly mechanical.

For input and output it used three paper-tape readers, two. (b) A Paper-Tape-Punch, (c) A Magnetic Tape, (d) A Magnetic Disk, (e) A Floppy Disk, (f) Screen or (g) A Printer. The Screen and the Printer are the mostly used output devices.

It is not that a computer can use only one input device and one output device at a time.A general purpose input channel and output channel system is provided f o r attaching a variety of input-output devices. Input and output transmissions are either a single 6-bit, 7-bit or 8-bit character, or a bit word.

Standard input-output is by punched paper tape high-speed read and punch units.The UDT is the general purpose, binary, high speed computer-designed especially for training within the military agencies.
