Parts that were once hand made at a cost of thousands of man-hours are now mass produced for a fraction of a rupee. Computer parts can be divided into two groups, hardware and software. Hardware is any part of the computer that you can touch.

The seeming miles of wires that get tangled on your desk, the CD drive, the monitor are all hardware.

Software is a set of electronic instructions consisting of complex codes Programs that make the computer perform tasks. Windows is a software, so is any other program that runs on your computer.

While there are thousands of parts even in the smallest computers that make up its hardware, you are not required to know them all. You only need to know about basic computer hardware.

The CPU is considered the brain of the computer. It performs all types of data processing operations, stores data, intermediate results and instructions program. It controls the operation of all parts of computer. A CPU has 3 components as listed below. Think of the ALU as the logical part of the brain. The ALU thinks in bits i. It is made up of a group of memory locations built directly into the CPU called registers. These are used to hold the data binary information that are being processed by the current instruction.

Primary memory is memory that is part of the computer itself and necessary for its functioning. It consists of mainly two types of memories:. As soon as the machine is switched off, data is erased. RAM is volatile. Volatile means that the data stored in memory is lost when we switch off the computer or if there is a power failure.

There are different types of RAM available. Some of them are described below. The memory from which we can only read but cannot write on it. This type of memory is non-volatile. The information is stored permanently in such memories during manufacture. A ROM, stores such instructions that are required to start a computer. This operation is referred to as bootstrap. The different types of ROM are given below. Floppy diskettes, hard disk, tapes and optical disks come under the category of external storage devices or ancillary storage devices.

These devices are very sensitive to environmental conditions humidity and temperature as well as to external magnetic fields and need to be stored carefully. Floppy disks are primarily used on PCs. Information on a floppy disk is recorded in the magnetized states of particles of iron oxides evenly placed upon concentric circles known as tracks. It is a non-removable enclosed magnetic disk included in most PCs.

It contains a stack of metal platters, each coated with iron oxide, that spin on a spindle and the entire unit is encased in a sealed chamber. This is plastic tape, usually made of Mylar that is coated with iron oxide, thereby enabling the introduction writing ; retention memory and reading of magnetically recorded information. The best use of tape storage is for data that you do not use very often.

Peripheral devices are devices connected to the computer externally. If a peripheral device is disconnected, the computer will still be able to work; only functions performed by this peripheral device will not be available. Here are the most used types of peripheral devices:. The most common and very popular input device which helps in inputting data to the computer. It consists of keys that are capable of inputting alphabets, numbers and special characters. You can also navigate using the keyboard and perform shortcut functions.

Mouse is the most popular pointing device and cursor-control device having a small palm size box with a round ball at its base which senses the movement of mouse and sends corresponding signals to CPU when the mouse buttons are pressed. It forms images from tiny dots, called pixels that are arranged in a rectangular form. The sharpness of the image depends upon the number of pixels.

It is a device used to move cursor position on a monitor screen. A scanner allows you to scan printed material and convert it into a file format that may be used within the PC. A plotter is used to create high-quality visuals on paper. A plotter gives a hard copy of the output.

It draws pictures on a paper using a pen. It can be used to create presentation-charts, graphics, tables and high quality technical drawings. There are two types of plotter. Computer Abbreviations. MS Word Keyboard Shortcuts. Try Computer Quizzes. Sign Up for Free Create free Account? Sign In.

Пуля попала в корпус мотоцикла и рикошетом отлетела в сторону. Беккер изо всех сил старался удержаться на шоссе, не дать веспе съехать на обочину.

 Вам нужно знать только одно: он будет найден. - Откуда такая уверенность. - Не я один его ищу. Американская разведка тоже идет по следу. Они, вполне естественно, хотят предотвратить распространение Цифровой крепости, поэтому послали на поиски ключа человека по имени Дэвид Беккер.
