Physical /Basic PC Components

Component	Description
Motherboard	The motherboard is the core of the system. It really is the PC; everything else is connected to it, and it controls everything in the system.
Processor	The processor is often thought of as the "engine" of the computer. It's also called the CPU (central processing unit).
Memory (RAM)	The system memory is often called RAM (for random access memory). This is the primary memory, which holds all the programs and data the processor is using at a given time.
Case/chassis	The case is the frame or chassis that houses the motherboard, power supply, disk drives, adapter cards, and any other physical components in the system.
Power supply	The power supply is what feeds electrical power to every single part in the PC.
Floppy drive	The floppy drive is a simple, inexpensive, low-capacity, removable-media, magnetic storage device.
Hard drive	The hard disk is the primary archival storage memory for the system.
CD-ROM/DVD-ROM	CD-ROM (compact disc read-only) and DVD-ROM (digital versatile disc read-only) drives are relatively high-capacity, removable media, optical drives.
Keyboard	The keyboard is the primary device on a PC that is used by a human to communicate with and control a system.
Mouse	Although many types of pointing devices are on the market today, the first and most popular device for this purpose is the mouse.
Video card	The video card controls the information you see on the monitor.
Monitor	A computer monitor or a computer display is an electronic visual display for computers. ... The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) or a flat panel LED display, while older monitors used a cathode ray tubes (CRT).
Sound card	It enables the PC to generate complex sounds.
Modem	Most prebuilt PCs ship with a modem (generally an internal modem).

32. Write down the difference Desktop and Laptop PC. (Jan-14, 15) 

         Answer: - 1

Desktop	Laptop
There is a wide variety of component options available for desktops.	Laptops can have a fairly wide variety of component options.
Desktops are large in size and have a separate monitor.	Laptops are very portable due to their compact size.
Desktop processors are a little bit larger in size, but this also means the desktop processors can be more powerful than laptop processors.	Laptop processors have nearly caught up to desktop processors, but are still limited when compared to desktop processors.
Setting up a desktop takes a bit of extra work to hook everything up, start it up, and begin to use. It also requires more space to set up.	Laptops are built to be easy to use, requiring little time to get running.
Desktops can make use of full size keyboards.	Smaller laptops with the 14" and 15" screens typically have smaller keyboards.
Desktop monitors can be 15" or larger. It is even possible to hook up a desktop to a TV, so screen sizes could be as large as a TV.	Since portability is a big feature of laptops, smaller screen sizes are necessary and screen sizes typically range from 10" to 17".
Most components in a desktop are easily removable, making it easier to upgrade and since desktop cases are usually much bigger they're easier to work in when doing any upgrading.	Memory and hard drive are about the only components that can be upgraded in a laptop. The remaining components are either built-in or not removable or the laptop is not designed to work with an upgraded version of a component.
Repairing a desktop computer is much easier since most of the hardware can be easily purchased off the shelf of any local computer retail store.	For most users opening a laptop to repair a part can be difficult and finding a replacement part often requires calling the computer manufacturer or ordering from another online site.

         Answer: - 2

Sl. No.	Desktop	Laptop
1.	Big in size	Small size
2.	Not easy to carry	Easy to carry
3.	Weight is high	Low
4.	Can’t use battery	Must use battery
5.	Use of room and Office	Use everywhere
6.	Design for stationary use, processor, monitor, keyboard, muse, should be attached	Laptop is all in one.

A laptop computer (also called notebook computer) is a computer that integrates all the elements that needs to run properly, including a battery power supply, a screen and a keyboard, in a small casing (on average 360 cm x 40 cm x 270 cm). Portable and compact personal computer with the same capabilities as a desktop computer. Laptop computers have an L-shape design and the screen can be lowered and closed to allow for easy transportation of the machine. The primary feature that attracts users to laptops over desktops is their portability. Laptop computers provide users the ability to run the machine using an internal battery or an outside power adapter. Laptops have dramatically decreased in size since their introduction in 1979. Laptops are usually more expensive than standard desktops and do not have the same life-span as fixed personal computers.

Answer:-2

Laptop computer is a modern creation of science. It is a package keyboard, mouse, monitor, CPU, Web cam all are have to attach to each other and then have to work but laptop is all in one. Before laptop it is not possible to carry a computer for all time. After coming laptop PC is very easy to use of computer at any place, without electricity.
