What is motherbord?

Motherboard

Alternatively referred to as the mb, mainboard, mobo, mobd, backplane board, base board, main circuit board, planar board, system board, or a logic board on Apple computers. The motherboard is a printed circuit board that is the foundation of a computer and allows the CPU, RAM, and all other computer hardware components to function and communicate with each other.
Below is a graphic illustration of the ASUS P5AD2-E motherboard and some basic explanations of each of the major portions of the motherboard. Clicking on the image below gives you a larger more detailed version of the picture below.

What is ROM?

ROM

Short for Read-Only Memory, ROM is a type of "built-in" memory that is capable of holding data and having that data read from the chip, but not written to. Unlike Random Access Memory (RAM), ROM is non-volatile which means it keeps its contents regardless if it has power or not.
AMIBIOS BIOS
A good example of ROM is EEPROM, which is a programmable ROM used for the computer BIOS, as shown in the above picture.
Tip: The term ROM is used to describe any type of memory or media that is read only. For example, a CD-ROM (Compact Disc Read-Only Memory) is a disc that can only be read from and a drive only capable of reading.

What is Mouse?

Mouse

Computer MouseA mouse is a hardware input device that was invented by Douglas Engelbart in 1963 while working at Xerox PARC, who at the time was working at the Stanford Research Institute, which was a think tank sponsored by Stanford University. The picture is of a Microsoft IntelliMouse and is an example of what a computer mouse may look like.
The mouse allows an individual to control a pointer in a graphical user interface (GUI) and manipulate on-screen objects such as icons, files, and folders. By using a mouse the user doesn't have to memorize commands, like those used in a text-based command line environment such as MS-DOS. For example, in MS-DOS a user would have to know the cd command and dir command to navigate to a folder and view the files. However, in Windows the user only has to double-click on the folder to view all the files.
The Mouse was originally referred to as an X-Y Position Indicator for a Display System. Xerox later applied the mouse to its revolutionary Alto computer system in 1973. However, because of Alto's unfortunate success, it was first widely used in the Apple Lisa computer. Today, a pointing device is found on virtually every computer.

What is Flopydisk Operating system?

Disk Operating System (specifically) and disk operating system (generically), most often reveal themselves in abbreviated form as DOS, refer to an operating system software used in most computers that provides the abstraction and management of secondary storage devices and the information on them (e.g., file systems for organizing files of all sorts). Such software is referred to as a disk operating system when the storage devices it manages are made of rotating platters, such as floppy disks or hard disks.
In the early days of microcomputers, computer memory space was often limited, so the disk operating system was an extension of the operating system. This component was only loaded if needed. Otherwise, disk access would be limited to low-level operations such as reading and writing disks at the sector-level.
In some cases, the disk operating system component (or even the operating system) was known as DOS.
Sometimes, a disk operating system can refer to the entire operating system if it is loaded off a disk and supports the abstraction and management of disk devices. Examples include DOS/360. On the PC compatible platform, an entire family of operating systems was called DOS.

What is resoning?

It is the process of differencing (making conclusions) and developing new facts from the existing facts.

What is understanding ?

It is the transformation of one representation in to another where second representation corresponds to set of available actions that can be performed and the mapping is such that for each event, there is an appropriate affecting the process of understanding .

what is keyboard?

Keyboard is On most computers, a keyboard is the primary text input device. (The mouse is also a primary input device but lacks the ability to easily transmit textual information.) The keyboard also contains certain standard function keys, such as the Escape key, tab and cursor movement keys, shift and control keys, and sometimes other manufacturer-customized keys.
The computer keyboard uses the same key arrangement as the mechanical and electronic typewriter keyboards that preceded the computer. The standard arrangement of alphabetic keys is known as the Qwerty (pronounced KWEHR-tee) keyboard, its name deriving from the arrangement of the five keys at the upper left of the three rows of alphabetic keys. This arrangement, invented for one of the earliest mechanical typewriters, dates back to the 1870s. Another well-known key arrangement is the Dvorak (pronounced duh-VOR-ak, not like the Czech composer) system, which was designed to be easier to learn and use. The Dvorak keyboard was designed with the most common consonants on one side of the middle or home row and the vowels on the other side so that typing tends to alternate key strokes back and forth between hands. Although the Dvorak keyboard has never been widely used, it has adherents.
Because many keyboard users develop a cumulative trauma disorder, such as carpal tunnel syndrome, a number of ergonomic keyboards have been developed. Approaches include keyboards contoured to alleviate stress and foot-driven pedals for certain keys or keyboard functions.

what is mouse?

device that controls the movement of the cursor or pointer on adisplay screen. A mouse is a small object you can roll along a hard, flat surface. Its name is derived from its shape, which looks a bit like a mouse, its connecting wire that one can imagine to be the mouse's tail, and the fact that one must make it scurry along a surface. As you move the mouse, the pointer on the display screen moves in the same direction. Mice contain at least one button and sometimes as many as three, which have different functions depending on what program is running. Some newer mice also include a scroll wheel for scrolling through long documents.

what is UPs?

Short for uninterruptible power supply, a power supply that includes a battery to maintain power in the event of a power outage. Typically, a UPS keeps a computer running for several minutes after a power outage, enabling you to save data that is inRAM and shut down the computer gracefully. Many UPSs now offer a software component that enables you to automate backup and shut down procedures in case there's a power failure while you're away from the computer.

what is CPU?

CPU (pronounced as separate letters) is the abbreviation forcentral processing unit.
Sometimes referred to simply as the central processor, but more commonly called processorthe CPU is the brains of the computerwhere most calculations take place. In terms of computing power, the CPU is the most important element of a computer system. CPU is the brain of computer system . CPU is the control processing unit. 

what is computer

computer is an electronic device that manipulates information, or data. It has the ability to storeretrieve, and process data. You can use a computer to type documents, send email, and browse the Web. You can also use it to handle spreadsheets, accounting, database management, presentations, games, and more.
