6. Motherboard
A motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, while providing connectors for other peripherals. The motherboard is sometimes alternatively known as the main board, system board, or, on Apple computers, the logic board. It is also sometimes casually shortened to mobo.

8. Central Processing Unit or Microprocessor
The central processing unit(CPU) performs most of the calculations which enable a computer to function, and is sometimes referred to as the "brain" of the computer. It is usually cooled by a heat sink and fan.

9. Memory
Random-access memory (usually known by its acronym, RAM) is a form of computer data storage. Today, it takes the form of integrated circuits that allow stored data to be accessed in any order . The word random thus refers to the fact that any piece of data can be returned in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data. ROM - read-only memory computer memory on which data has been prerecorded. Once data has been written onto a ROM chip, it cannot be removed and can only be read.

10. Types Of RAM 240 pin DDR3 288 pin DDR4
Synchronous Dynamic Random Access Memory (SDRAM)
Double Data Rate(DDR)

11. Hard Disk Drive
A hard disk drive (often shortened as hard disk, hard drive, or HDD) is a non-volatile storage device that stores digitally encoded data on rapidly rotating rigid platters with magnetic surfaces.

13. SATA - Serial Advanced Technology Attachment
The SATA standard defines a data cable with seven conductors (3 grounds and 4 active data lines in two pairs) and 8 mm wide wafer connectors on each end
IDE - Integrated Drive Electronics
40-pin connectors generally attached drives to a ribbon cable. Each cable has two or three connectors, one of which plugs into an adapter interfacing with the rest of the computer system.

14. Optical Drive
In computing, an optical disc drive (ODD) is a disk drive that uses laser light or electromagnetic waves near the light spectrum as part of the process of reading or writing data to or from optical drive. Some drives can only read from discs, but recent drives are commonly both readers and recorders. Recorders are sometimes called burners or writers. Compact Disc (CD), Digital Video Disc, (DVD) and Blu-ray (BD), are common types of optical media which can be read and recorded by such drives.

15. 3 Common Types Optical Drive
700 MB (up to 80 minutes audio)
4.7 GB (single-sided, single-layer) 8.5 GB (single-sided, double-layer)
25 to 50 GB (single-layer) 50 to 100 GB (dual-layer)

16. Input Devices
Input / Output, or I/O, refers to the communication between an information processing system (such as a computer), and the outside world possibly a human, or another information processing system. Inputs are the signals or data received by the system, and outputs are the signals or data sent from it.

17. Input Device
The keyboard is very simple to operate, and touch-typing aside, most people can operate a keyboard well enough. The keyboard is usually the primary input device for a PC, which is why people can become emotional when it breaks.

18. Input Device
In computing, a mouse is a pointing device that functions by detecting two - dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons. (Although traditionally a button is typically round or square, modern mice have spring-loaded regions of their top surface that operate switches when pressed down lightly.) It sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations, or extra buttons or features that can add more control or dimensional input. The mouse's motion typically translates into the motion of a cursor on a display, which allows for fine control of a graphical user interface.

19. Output Device
Printer - A printer is a peripheral which produces a hard copy (permanent human-readable text and/or graphics) of documents stored in electronic form, usually on physical print media such as paper or transparencies. Many printers are primarily used as local peripherals, and are attached by a printer cable or, in most newer printers, a USB cable to a computer which serves as a document source. Some printers, commonly known as network printers, have built-in network interfaces (typically wireless or Ethernet), and can serve as a hardcopy device for any user on the network. Individual printers are often designed to support both local and network connected users at the same time.

20. Output Device
A thin film transistor liquid crystal display (TFT-LCD) is a variant of liquid crystal display (LCD) which uses thin film transistor (TFT) technology to improve image quality (addressability, contrast). TFT LCD is one type of active matrix LCD, though all LCD-screens are based on TFT active matrix addressing

21. Software
Computer software, or just software is a general term primarily used for digitally stored data such as computer programs and other kinds of information read and written by computers. Today, this includes data that has not traditionally been associated with computers, such as film, tapes and records. The term was coined in order to contrast to the old term hardware (meaning physical device) in contrast to hardware, software is intangible, meaning it "cannot be touched".

23. System Software
The purpose of systems software is to unburden the applications programmer from the often complex details of the particular computer being used, including such accessories as communications devices, printers, device readers, displays and keyboards, and also to partition the computer's resources such as memory and processor time in a safe and stable manner. Examples are - Windows XP, Linux, and Mac OS X.

24. Application Software
Application software, also known as software application, application or app, is computer software designed to help the user to perform a singular or multiple related specific tasks. Typical examples are word processor/ spreadsheet, media players database application.
