Laptop is a kind of personal computer designed for mobile use. It incorporates most of the technical components of a desktop computer. Laptops are normally note-book in shape. Today it is becoming irremissibly a handy device for every student. Also they do not weigh much, hence not resulting in any issue with the portability.

ACTIVE MATRIX:

It indicates a display system where each pixel is separately controlled by a matrix of thin-film transistors.

ASPECT RATIO:

This indulges with the relationship of width and height. Aspect ratio must be kept the same when an image is displayed on different screens to avoid stretching of image in either vertical or horizontal direction. Normal ratio is given as 4:3, while for HDTV it is 16:9.

ATA:

Advanced Technology Attachment is a special type of drive which incorporates the drive controller directly on the drive itself.

BATTERY:

This supplies the power source to the laptop. These are re-chargeable batteries. They are available in Nickel cadmium (NI-CD) and Nickel metal Hydride (NI-MH).

BAYS:

A space at the frame of  laptop PC used to install an internal drive.

BIOS:

Basic Input and Output System is a pre-installed program on windows based computers.

BLUETOOTH:

This is a wireless technology that eases the communication between Bluetooth-compatible devices.

BUFFER:

A type of memory used to store temporary results thereby helping in fast transfer of data from one device to another

BUS:

This specifies the path between CPU and input/output devices.

COMBO-DRIVE:

Combo-drive is one type of optical drive that blends the ability of both reading and recording.

CHARGER:

Charger is used to offer energy into battery by passing electric current through them. Different batteries demand for different amounts of charge.

CHIPSET:

This cites the group of integrated chips or circuits. Main purpose is to control the communication between processor and external device.

CLOCK FREQUENCY:

This specifies the speed of the computer components. It is denoted in hertz.

DBEF:

DBEF stands for dual brightness enhancement film which is used to increase the LCD screen brightness.

DDR:

Double Data Rate refers to the memory speed. Many version are available like DDR 1, DDR 2 , DDR 3 etc. Each have different memory speeds.

DEFRAGMENT:

Defragmentation is the process of organizing the information or data on a hard-disk. By this data can be located and retrieved as quickly as possible.

DRIVER:

This denotes the software that comes with a peripheral. They allow the devices to communicate with the computers operating system.

ETHERNET:

Ethernet is a wired network technology available through LAN.

EXPANSION SLOT:

The slot indicates a socket on the motherboard into which an expansion board can be inserted.

FAT32:

Fat Allocation Table is a disk-formatting scheme.

GUI:

Graphic User Interface is abbreviated as GUI. It displays software and application in a graphic environment.

HARD DRIVE:

It refers to the physical space on a computer. The physical measurement is done in gigabytes (GB). Here the data remains even if power is switched off.

HARDWARE:

This is the physical components of the computer or laptop. The hardware can be external or internal. Software will have certain hardware requirements for efficient functioning.

JOYSTICK:

A device used for playing games. It has a base and a stick which controls the direction.

LENOVO:

They are one of the largest manufacturers of computers in the world. They design innovative products which meets the consumer’s needs.

MOTHERBOARD:

Mother board is the main circuit board of the laptop. This encloses all important components of laptop like ROM, USB ports, controllers for hard drive, keyboard etc.

NETWORK CARD:

It’s a computer hardware which offers communication over a computer network.

NIC:

Network Interface Card. This card must be installed on every laptop since this will be a part of local-area network.

OPERATING SYSTEM:

Operating system is the interface for the hardware and software. Some operating systems are windows, UNIX, LINUX, Vista, XP etc.

OPTICAL DRIVES:

These are the CD or DVD drives that come with the laptop. The speed of these drives refers to how quickly the information can be written on CD or DVD.

PROCESSOR TYPE:

Processors will be available like Pentium, Celeron, AMD, etc. Each processor will have different speeds and manages the heating process of the laptop.

RAM:

RAM is the short for random access memory. It is a temporary storage area used by the processor for executing programs and also to hold data and results. A laptop with low RAM will take lot of time to load and to do any process.

RESOLUTION:

This is the measurement of picture clarity which is based on the number of pixels to reproduce image.

SATA:

SATA is the acronym for Serial Advanced Technology Attachment. It is the interface through which hard drives are connected to motherboard. IDE is another interface providing the same features.

SDRAM:

SDRAM stands for synchronous dynamic random access memory. This is a type of RAM which is considerably faster and more reliable than the standard RAM.

SOFTWARE:

A collection of programs that is installed on laptop which is readily in usable form is software. They perform specific task on the system.

SONY VAIO:

Sony Vaio is the world’s leading manufacturer of computer peripherals. It is widely popular because of its brand name. Sony offers the most number of laptop models. Their products certainly look the part, and it doesn’t lack any features.

TOSHIBA:

Toshiba is one of the world class innovators which operate globally with their ingenious products. They drive the technology to new era every time. Their products are rated much higher because of their unique commitment to innovations.

USB:

IT denotes universal serial bus. This acts as the connecting point for external devices. Normally 2 USB ports are standard but with its popularity even 3 or 4 are possible.

VGA: (VIDEO GRAPHICS ARRAY)

This specifies the resolution of the screen and the simultaneous colors present in it.

WEBCAM:

This is a small digital video camera which has low resolution. Most widely used for videoconferencing and chatting.

WI-FI:

Wireless Fidelity is abbreviated as Wi-Fi. It denote wireless internet. This allows a laptop to access internet without any wires connected to laptop.
