The motherboard is the part of the computer where such things as the processor, memory modules, expansion cards and external devices are attached. They include storage devices and input/output devices.Ĭomputer case.The computer case contains the most important components of the computer: the motherboard, the processor, random access memory modules, the hard drive etc.
Peripherals are the physical units attached to the computer. In a way, it is the “brain” of the computer. Its function is to execute program instructions and coordinate the activities of all the other units. Perhaps the most influential component is the central processing unit. There are three basic hardware sections: the central processing unit (CPU), main memory and peripherals.

Software is a set of instructions, called a program, which tells the computer what to do. Hardware is any electronic or mechanical part you can see or touch. That’s why your computer has a little fan blowing away – to stop its brain from overheating!Ī computer system consists of two parts: hardware and software.
It works amazingly hard and gets incredibly hot in the process. Your computer’s processor (CPU) is a microchip buried deep inside. You may have an ink-jet or laser printer too to make an output. As for output, your computer has a screen and stereo loudspeakers. But smaller, computer-based devices like digital cameras and cell-phones use other kinds of storage such as flash memory cards. Your computer stores all your documents and files on a hard-drive: a huge magnetic memory. Your keyboard and mouse, for example, are input units – ways of getting information into your computer that it can process, if you use a microphone and voice recognition software, that’s another form of input. It takes in raw information (or data) at one end (input), processes it, stores it until it is necessary (memory) and then spits out the results at the other end (output). What is a computer? A computer is an electronic machine that processes information – in other words, an information processor. Реферат: Computer Hardware and Functionality of the Computer
