Fundamentals of Computers

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.

Memory and Storage Systems 4. They help the users in saving a lot of time. New Perspectives on Microsoft Office balagurusmy Contains all the properties of hard disk drives to store the data and use solid-state memory, which has no moving parts. But it is very bulky and occupies a lot of space on the desk. With the help of pointing devices, we can easily select the icons, menus, windows, etc on the Graphical User Interface.

They are high-speed memory locations used for holding instructions, data and intermediate results that are currently being processed. The dark areas appear light and the light areas appear dark. ROM is most commonly used in devices such as calculators, laser printers, etc.

ROM does not allow the random access of data, and allows sequential access of data. Balwgurusamy are similar to the normal recording tapes. Help perform specific tasks, such as searching a file or refreshing a web page; 3 Central keys: It also consumes a lot of power and produces a large amount heat. A projector consists of an optic system, a light source and displays, which contain the original images. To make this website work, we log user data and share it with processors.


Sand table, Abacus, … Automated Computing Devices: Use Ultra Large Scale Integration technology that allows almost ten million electronic components to be fabricated on one small chip. The DRAM needs to be continuously refreshed with power supply because the capacitor has the tendency to get discharged. Most popularly, the OMR devices are used for scanning the documents having multiple choices as in the question papers used in schools, colleges, etc.

The fastest type of computer that can perform complex operations at fudnamentals very high speed. Registration Forgot your password? The CPU can identify each cell by its address. PMT is used for identifying the light emitted by the weak signals. A computer includes various devices: A professor of mathematics a the Cambridge University is considered to be the father of modern computer.

As the frequency of light changes, these scanning devices detect the change and the output obtained after scanning also gets accordingly changed. An LCD monitor is small in size and light in weight so it occupies less space on the desk. 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.

The optical recognition devices basically make use of optical scanner for inputting data. These pens change their positions and draw continuous lines to produce an image.

A computer is an electronic machine that takes input from the user, processes the given input and generates output in the form of useful information. These needles help in encoding a single bit of information by getting polarized balgurusamy one direction represented by 1, and opposite direction represented by 0.

These devices were specially developed for the banking operations. Data Communications and Networks It also provides a change in the resolution without affecting the clarity of the picture. Commonly used optical recognition devices are: Understanding the Computer 2. We think you have liked this presentation. About project SlidePlayer Terms of Service.

Magnetic tapes, magnetic disks, hard disks, floppy disks are examples of magnetic storage systems. computsrs

The result computed in the execution phase is either sent to the memory or to an output device. The data stored on the magnetic tapes can be accessed using the sequential access method. The voice recognition system only recognises the voice of the speaking person rather than what he speaks. However, it has a weak color quality as compared to a CRT monitor. The arithmetic operations can be addition, subtraction, multiplication or division.

Projects were initially used for showing films but now they are used on a large scale for displaying presentations in various situations. Most computers use a group of eight bits, known as a byte, to represent a character. A CRT monitor has many advantages, such as a high contrast ratio and color lf. DRAM retains the data for a very short span of time, even after the power supply is switched off.

If you wish to download it, please recommend it to your friends in any social system. It is mostly used in video games and electronic dictionaries.
