Hardware Overview – A Simple Explanation

Computer hardware comprises all the internal components of a personal computer, including the computer case, hard drive, central processing unit, main input device, mouse, keyboard, hard disk, computer memory storage, video card, motherboard and sound card. The term “hardware” can also be used to refer to any software accessory that is part of the hardware. Some examples of hardware accessories are the CD ROM drive, the CD Writer, the CD Video card, the DVD writer, printers and scanners. Major manufacturers of personal computers include Dell, Apple, Compaq, eMachines, Gateway, iLocalis, Laptop, Microsoft, Saitek, Sharp, Sony and Toshiba.

A PC consists of many different hardware components, most of which are peripheral devices. Peripheral devices, usually referred to as “periphery hardware” refer to any additional equipment that is built into the PC to increase the functionality of the main processing unit (CPU). Examples of commonly added peripheral hardware in today’s modern computers include a CD ROM drive, a CD Writer, an LCD monitor, a keyboard, a mouse and a printer. Peripheral devices add to the functionality of the CPU by providing access to digital media such as audio and video. They are sometimes also found integrated within the CPU itself.

Central processing unit (CPU) is the software component that controls the execution of instructions stored in the form of program code in the form of instruction or control flow language. The information that is run through the CPU is controlled by the central processing unit (CPU) which is found inside the computer case. The other components of computer hardware are the memory and the graphics card. The graphics card is responsible for providing the images that are displayed on the screen of the personal computer.

The other major component of the desktop computer case is the keyboard. The most widely used keyboard is the mechanical type that operates with the use of mechanical keys or pressure. This kind of keyboard facilitates the comfortable use for people who are typing using the keyboard. On the other hand, a laser Typewriter keyboard is capable of providing more than one hundred thousand characters per minute. The other hardware refers to the monitor and the mouse.

Desktop computers usually come equipped with built-in hard disk storage and CD storage drive. The latter two types of storage drive are not always included in the packaged desktop computers because they can be bought separately. In addition, the sound card is also commonly installed in the computer systems as well as the video display.

The physical parts of the desktop computer hardware system refer to the various elements found in the CPU. These include the registers, timers, input and output devices, bus controllers, expansion slots, bus interface units, voltage controllers, power supply and thermal management elements. The video subsystem is responsible for converting the visual signals produced by the CPU into the required ones for executing the instructions contained in the program. The sound subsystem handles all the sounds that come out of the CPU. All the previously mentioned hardware components play an important role in making the CPU function.
