The arithmetic operations can be addition, subtraction, multiplication or division. These needles help in encoding a single bit of information by getting polarized in one direction represented by 1, and opposite direction represented by 0. A projector consists of an optic system, a light source and displays, which contain the original images. They are high-speed memory locations used for holding instructions, data and intermediate results that are currently being processed.

Understanding the Computer 2. They act as an interface between the computer and the user. Typically, capacities are described using the unit of byte as follows: Designed to be used by individuals.

These pens change their positions and draw continuous lines to produce an image. We can balagurusammy a keyboard to type data and text and execute commands.

Different types of display monitors use different technology for displaying the data. Use liquid crystals technology to display the images. Data Communications and Networks The basic task of a scanning devices is to convert an image or the textual data into digital data, i.

Breaking down the instruction into different parts, so that it can be easily understood before being processed by the CPU. ROM is most commonly used in devices such as calculators, laser printers, etc.

The interface unit acts as an intermediary between the processor and the device controllers of various peripheral devices in the computer system.

They help the users in saving a lot of time. These printers spray ink on the paper with the help of a nozzle. They are similar to the normal recording tapes. The plotters were used as a substitute to the colored printers when the printers were very expensive and were also not capable of drawing bigger images such as graphs.

The basic application of a voice output system is in Interactive Voice Response systems, which are used by the customer care or customer support departments of an organization, such as telecommunication companies, etc. These systems allow users to communicate with computers directly without using a keyboard or mouse.

The voice recognition devices are used for various purposes such as dictation, training air-traffic controllers, etc. The display screens, which are available today, support many fonts and colors. We think you have liked this presentation.

Also, the power consumption by an LCD monitor is very less. The main task of an output device is to convert the machine readable information into human-readable from which may be in the form of text, graphics, audio or video.

These devices prove to be of great use in recognizing characters in question sheets, enrolment forms, registration forms, employee payroll, etc.

The resultant matrix is known as bit map and is displayed on the screen. These scanners are also known as film scanners as they can easily scan the original image of the film. The data acquisition system collects the electrical fundamebtals from various devices and converts them into the digital signals for further assessment.

The dark areas appear light and the light areas appear dark. SRAM uses a number of transistors to store a single bit of digital information. But it is very bulky and occupies a lot of space on the desk. It is the main memory of the balaggurusamy system that stores the data temporarily and allows the data to be accessed in any order. Can store any type of data, such as text, audio, video, image. With the help of pointing devices, we can easily select the icons, menus, windows, etc on the Graphical User Interface.

A professor of mathematics a the Cambridge University is considered to be the father of modern computer.
