Overview : A computer is an electronic device that can receive, process and store data. Computer basically works in I-P-O process.
I : Input ; P : Process & O : Output
In a Computer all numbers, text, sound, images, animations, and video used as input are called data. And all Input data returned as output are called information.Input is the raw data entered into the computer by using input devices.
In a Computer storage device is an apparatus for storing data and information.
One of the most common input devices is the keyboard, used to enter text.
Hardware of Computer System : In a Computer "Hardware" refers to the physical elements.A basic computer consists of 4 components.
Examples of Computer Hardware :
RAM : RAM or Random access memory is the place in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device's processor. RAM is a hardware device that allows information to be stored and retrieved on a computer.RAM is usually associated with DRAM, which is a type of memory module. Because information is accessed randomly instead of sequentially like it is on a CD or hard drive, the computer can access the data much faster. However, unlike ROM or the hard drive, RAM is a volatile memory and requires power to keep the data accessible. If the computer is turned off, all data contained in RAM is lost.
Hard disk drive (HDD) : A hard disk drive (HDD) is a data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. A hard disk drive -- often shortened to hard drive -- and hard disk are not the same thing, but they are packaged as a unit and either term can refer to the whole unit. Hard disk drives can be found in desktop computers, mobile devices, consumer electronics and enterprise storage arrays in data centers.
Compact disk : Compact disc (CD) is a digital optical disc data storage format released in 1982 and co-developed by Philips and Sony.The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM).CDs can hold up to 700 MB worth of data, which is approximately 80 minutes of audio. Mini CDs have also been crated that can store approximately 24 minutes of audio or program drivers.
Solid-state drive : A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently.Solid-state drives actually aren't hard drives in the traditional sense of the term, as there are no moving parts involved. A traditional hard disk drive (HDD) consists of a spinning disk with a read/write head on a mechanical arm called an actuator.
CPU : CPU or Central Processing Unit is an internal component of the computer. Modern CPUs are small and square and contain multiple metallic connectors or pins on the underside. The CPU is inserted directly into a CPU socket, pin side down, on the motherboard.
CPU is the computer component that's responsible for interpreting and executing most of the commands from the computer's other hardware and software.The CPU attaches directly to a CPU "slot" on the motherboard. The CPU is inserted into the socket pin-side-down, and a small lever helps to secure the processor.
The clock speed of a processor is the number of instructions it can process in any given second, measured in gigahertz (GHz).
Some devices have a single-core processor while others may have a dual-core (or quad-core, etc.) processor.

Motherboard : In a Computer The motherboard serves to connect all of the parts of a computer together. The CPU, memory, hard drives, and other ports and expansion cards all connect to the motherboard directly or via cables.
The motherboard is the piece of computer hardware that can be thought of as the "backbone" of the PC, or more appropriately as the "mother" that holds all the pieces together.
Expansion cards : In a computer the expansion card, expansion board, adapter card or accessory card, is a printed circuit board that can be inserted into an electrical connector, or expansion slot on a computer motherboard, back-plane or riser card to add functionality to a computer system via the expansion bus.
Some of Expansion Cards are;
Graphics Card : A graphics card is an expansion card which generates a output images to a display.
Megabyte :
A megabyte, or MB, is a unit of data that equals 1,048,576 bytes. It is equal to a kilobyte squared, (1024)2.
Gigabyte :
A gigabyte, or GB, is a unit of data that equals 1,073,741,824 bytes. This is equal to a kilobyte cubed, (1024)3.
Terabyte :
A terabyte, or TB, is a unit of data that equals 1,099,511,627,776 bytes. This is equal to a kilobyte to the fourth power, (1024)4.Approximately one trillion bytes.
Petabyte :
A petabyte, or PB, is a unit of data that equals 1,125,899,906,842,624 bytes. This is equal to a kilobyte to the fifth power, (1024)5. Roughly one quadrillion bytes.
Measurement :
Measurement for data speed. Data transfer speeds can be measured in bits per second, or in bytes per second.
BPS : It is known as bits per second, bps was the main way of describing data transfer speeds several decades ago.
KBPS : Kilobits per second, or 1000 bits per second. The quality of compressed audio files are typically measured in Kbps.
MBPS : Megabits per second, or 1,000,000 bits per second. Internet service providers usually measure their Internet connectivity in Mbps.
GBPS : Gigabits per second, or 1,000,000,000 bits per second. Internet infrastructure, and consumer Internet connections in some countries can operate at these speeds.

Hardware of Computer System : In a Computer "Hardware" refers to the physical elements.A basic computer consists of 4 components.
- Input device
- CPU (Central Processing Unit)
- Memory
- Output device
Input unit and Output (I/O - Process)
In a computer system I/O process is the process where in computer need to put information after that in Cpu it goes for process after that finally it gives output.
