  1. 1. Contents Definition Basic parts of computer Characteristics Real world application Limitation
  2. 2. A computer is an electronic device, operating under the control of instructions (software) stored in its own memory unit, that can accept data (input), manipulate data (process), and produce information (output) from the processing. Generally, the term is used to describe a collection of devices that function together as a system.
  3. 3. An input device is any device that provides input to a computer. A mouse is a type of input device. By sliding the mouse along the desk surface, the user can move objects on the screen, draw pictures, and select actions to be performed by pressing one or more buttons. Keyboard is the most popular input device that allows users to type alphabets, numbers, and operators, and also to control the cursor on the screen. : An alternative to the traditional mouse and often used by graphic designers. Another type of hardware that can be used for inputting information is called a joystick. It is much easier to play some games with a joystick than with keyboard keys. If you plan to play a lot of games, you may wish to get a joystick.
  4. 4. electronic or electromechanical equipment connected to a computer and used to transfer data out of the computer in the form of text, images, sounds, or other media Monitor, which again is a very essential part of the computer system, displays the actions that the computer performs on our command. The printer is used for putting documents on paper. Plotters are expensive output devices specially designed to produce outputs of diagrams, illustrations and other graphics. Speakers are also included in basic elements of a computer. It is not indispensible, because a computer can perform its function without speakers. However, we use them to for multiple purposes.
  5. 5. In general, no human being can compete to solving the complex computation, faster than computer. Since Computer is programmed, so what ever input we give it gives result with accurately. Computer can store mass storage of data with appropriate format. Computer can work for hours without any break and creating error. We can use computer to perform completely different type of work at the same time. It can remember data for us.
  6. 6. 1. Computers in Business: They are used in keeping records of daily sales and profits. Computers are also used to prepare materials to promote the products of the business establishments. 2. Computers in Engineering: Engineers use computers to create the design of a complex object using a computer program for Computer-Aided Drafting. 3. Computers in the Government: Computers are used to keep records of the people that the government serves. Several government agencies use computers to facilitate the task they are required to give to the people. 4. Computers at Home: Computers are used at home for recreational purposes. You can listen to music, watch movies and play games. 5. Computers in Manufacturing: Computers are used in manufacturing to manipulate machine that perform dangerous tasks or tasks that are repeatedly done. 6 . Computers in School :Students use computers to study various computer applications. 7. Computers in Science: Computers are used in science to stimulate experiments, which are dangerous to perform in real life. Computers are also used to record data and information derived from experiments.
  7. 7. 1. No Self Intelligence: Computer does not have any intelligence of its own. It works according to the instruction only. 2. No Decision-Making power: Computer cannot take any decision of its own. It does only those tasks which are already instructed to it. 3.No learning power: Computer has no learning power. Once you give instructions to a computer how to perform a task, the very task is cannot perform if you do not give it any instructions for the next time 4.Self Care: A Computer can not care itself like a human. A computer is dependent still to human beings for this purpose. 5. No Feelings: Computer doesn’t have feelings like human.
