MOTHERBOARDMotherboard refers to as a printed circuit board (PCB) also known as system board, main board, logic board or many other names. It holds the communication between many electronic components of a system like central processing unit (CPU) and memory and provides keys/connectors for other peripheral. Motherboard contains RAM or ROM chips, sound cards, graphic cards, SATA connector, CMOS battery backup, Floppy drive connector, CPU fan and many more.KEYBOARDKeyboard contains various keys on which different characters, latter, numbers and some special characters are printed on them. Whenever user gives an input by pressing any key, the character print on that key comes as an output which can see on computer screen also called monitor. Hence it becomes the main input device of computer. Every computer contain on-Screen keyboard we can also give input through it without any interruption. On-Screen keyboard plays important role during any key of your keyboard had junked or you have not any keyboard.HARD DISK DRIVEHard Disk Drive (HDD) also known as hard drive or fixed disk. It is a digital-data storage device which is used for storing and retrieving thousands bytes of data /information. HDD is non-volatile memory that mean store data can be retain even when power is turned off. It is a secondary storage device for general purpose computers. In HDDs data is accessed in a random-access manner it means that the individual block of information or data can be store and retrieve in any order and not only sequentially approach. MONITORMonitor comes under computer hardware devices. It is a display screen which can be CRT, LCD or LED like TV on which you can see videos and graphic information generated by computer. It has high display resolution.OPERATING SYSTEMOperating system is a software on which different applications and programs are executing simultaneously to produce output or result. There are several of OS present today, most popular OS is Windows, Linux and Mac OS. OS has different types such as real time OS, Distributed OS, multiuser OS etc. Operating system has many advantages such as it is multi-tasking, easy to use, reliable so user gain better experience during execution of processes. MOUSEMouse is a peripheral device of computer. It is an input device that is used with PCs. Moving mouse along with the flat surface it move the cursor on the monitor as the same way. There are two buttons, by right clicking a button you can select a program and by left clicking it will give you some extra information.CPUCentral Processing Unit known as CPU is the main part of computer. It is brain of a computer in which several arithmetic and logical operations are performed. It has two main parts one is Arithmetic Logic Unit in which arithmetic operations like + - * / are performed and second is Control Unit (CU) that directs operation of the processor.
