Input device

INPUT AND OUTPUT DEVICES In computing, input/output, or I/O, refers to the communication between an information processing system (such as a computer), and the outside world possibly a human, or another information processing system. Inputs are the signals or data received by the system, and outputs are the signals or data sent from it. The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation. I/O devices are used by a person (or other system) to

Wearable shield and self-defence device Date of filing: 2006 Name of filing company: David C. Brown Details: A defense device is a device that incorporates a shield and an electric shock gadget. The shield is designed to shield a client and hardware from physical assault. The individual guard gadget is designed to be worn by an individual with the end goal that it is impossible for an assailant to take it off the individual amid an assault. A personal defense device that includes a shield member configured

Central processing unit (CPU) is where all the calculations take place within the computer system. The CPU connects directly to a socket on the motherboard. The processor is responsible for carrying out instructions (programs), it can take inputs from input devices such as a keyboard or mouse, and then use this to create an output to be displayed on a monitor or for printing. Motherboard- The motherboard contains the basic circuitry, and many of the components connect to it. The motherboard is

wired or wireless. Output devices We use output devices to be able to do certain things, and the difference between output and input devices are, input devices is anything that is sent into computer whereas output devices is the opposite when things are sent out and some of those output devices consist of; Printer Monitor Sound A printer is an output device because data from the computer is being printed out meaning data is going out of

capabilities. Interfaces should not be limited merely to the screen, which forms the intermediary between the user and the results of the computer processes. Rather, the subsidiary devices should also be brought into the equation. In a sense, computer interfaces could be seen as a ‘peer’, or as one who responds activity to user input, as a reflection and a response lf the user’s feeling and emotions, to

Computer Input Technologies Introduction The interaction between humans and the machine is a relatively new science. When considering how the inputs to a computer started out, it is interesting to observe just how little has changed. For example, the QWERTY keyboard as part of the typewriter invented in the 1870s(2) far predates the concept of the modern digital computer as described by Alan Turing in 1936(3). Our tools to interact with our own machines have however been refined to be more convenient

the information system such that to interacts with the customers and the suppliers, to manage theiroperations, manage the accounts, fast way to intracts with the customers and the suppliers. In information system, the process works in the form of input and output. The output generated is the desired result or the objective that the firm want. Based on that output the other process continues. Components of Information System: As above we say that a system consist of a set of subsystem that

III EXECUTIVE SUMMARY Tablet computers are compact wireless mobile computing device which is in the size of a book which replaces the use of computing devices. Tablet computers can let us replace many things which computers can do. Other than surfing net, playing games for entertainment tablet computers has developed to a higher level where it is used in corporate world too for business purposes. However, definitely tablet computers also have both good
