A typical hardware set-up of a desktop computer consists of many components.
These components can usually be put together with little knowledge to build a computer. The motherboard is the part of a computer that connects all devices together. The memory card(s), graphic cards and processor are mounted directly onto the motherboard (the processor in a socket and the memory and graphic cards in expansion slots). The mass storage is connected to it with cables and can be installed in the computer case or in a separate case. This is the same for a keyboard and a mouse, except that they are external and they are connected to the I/O panel on the back of the computer. The monitor is also connected to the I/O panel, either through the onboard port on the motherboard, or the port on the graphic card.

A PC main memory is fast storage that is directly accessible by the CPU, and is used to store the currently executing programme and immediately needed data. PCs use semiconductor random access memory (RAM) of various kinds such as DRAM or SRAM as their primary storage. The main memory is much faster than mass storage devices like hard disks or optical discs, but it is usually volatile, it does not retain its contents (instructions or data) in the absence of power.

A visual display unit is a piece of electrical equipment, usually separate from the computer case, which displays viewable images generated by a computer without producing a permanent record. The word “monitor” is used in other contexts; in particular in television broadcasting, where a television picture is displayed to a high standard. A computer display device is usually either a cathode ray tube or some forms of flat panel such as TFT LCD.

In computers, the keyboard is an arrangement of buttons that each corresponds to a function, a letter or a number. They are the primary devices of inputting text. In most cases, the keyboards contain an array of keys specifically organized with the corresponding letters, numbers, and functions printed or engraved on the button. They are generally designed around an operator’s language, and many different versions for different languages exist. In English, the most common layout is the QWERTY layout, which was originally used in typewriters.

A mouse is a small, slidable device that users hold and slide around to point at, click, and sometimes drag objects on the screen in a graphical user interface using a pointer on the screen. Almost all personal computers have a mouse. A mouse can be plugged into a computer rear mouse socket, or as USB (device), or, more recently, may be connected wirelessly via USB antenna or Bluetooth antenna.
