 Hardware Components

Your computing experience is made up of interactions with hardware and software. The hardware is all the tangible computer equipment, such as the monitor, central processing unit, keyboard, and mouse. The main body of a computer is the system unit. The system unit’s case houses a number of essential components.

1. The Central Processing Unit (CPU) is responsible for processing most of the computer’s data, turning input into output.
As you might imagine, the speed and performance of the CPU is one of the biggest factors that determines how well a computer works. A CPU is a very small, thin silicon wafer that is encased in a ceramic chip and then mounted on a circuit board. 
CPU speed is measured in gigahertz (GHz). The higher this measurement, the faster the CPU can operate. A hertz is a cycle per second; a gigahertz is 1 billion cycles per second. CPU speed is not the only measurement of its performance, though; different CPU's have efficiency-boosting technologies built into them that can increase data throughput in a number of ways.  

2. Memory consists of computer chips that hold data.
One type of memory, called Random Access Memory (RAM), forms the central pool of memory that a computer uses to operate. The more RAM a computer has, the more applications it can have open at once without the computer’s performance starting to bog down. More RAM can also make some applications perform better in general.
Memory capacity is measured in gigabytes (GB), which is a billion bytes. Most basic computers have at least 4GB today, with higher end systems having 16GB or more. Like the CPU, memory consists of small, thin silicon wafers, encased in ceramic chips and mounted on circuit boards. The circuit boards holding memory are called DIMMs, which stands for dual inline memory module.

3. A Hard drive stores software.
When the computer is turned off, whatever is on the hard drive remains there, so you don’t have to reload software every time you turn on the computer. The operating system and your applications load from the hard drive into memory, where they run.
Hard-drive capacity is also measured in gigabytes (GB), like memory. A typical hard drive might be 500 GB or even 1 terabyte (1,000 GB) or more. Most hard drives sold today are the traditional mechanical type that use metal platters to store data with magnetic polarity, but a newer type, called a solid state hard drive (SSHD), uses a type of memory, resulting in a fast, quiet, and reliable (but expensive) storage alternative.

4. Accessories -  In addition to the components in the system unit, a computer may come with one or more input devices.


  • keyboards
  •  mice
  •  trackballs 
  • touch pads
  • USB hubs


5. Display screen.
Depending on the type of computer, the display screen may be built-in, or may be a separate unit called a monitor with its own power cord, as shown. Some displays are touchscreen, so you can use your finger on the screen to provide input to the computer.
Display quality is measured in resolution — that is, the number of pixels (individual colored dots) that comprise the display at its highest resolution. A typical resolution for a notebook PC is 1920 x 1080, for example. The first number is the horizontal resolution and the second one is the vertical resolution.
