R AM is a kind of computer memory that temporarily stores information, improving your

systems performance. Or in other words R AM simply holds data for the processor.

Types of R AM; SD R AM, DD R , DD R 2 and DD R 3.

SD R AM(Synchronous Dynamic R andom Access Memory)

SD R AM is Single Data R ate meaning that SD R AM can accept one command and transfer one word of data per clock cycle.

Typical speeds of SD R AM are 100 and 133 MHz

DD R SD R AM:

DD R SD R AM stands for double data rate synchronous dynamic random access memory.DD R R AM transfers data twice per clock cycle, hence the name double data rate.

DD R clock speeds range between 200 MHz (DD R -200) and 400 MHz (DD R -400).DD R -200 transfers 1600 M B /s, while DD R -400 transfers 3200 M B /s.

RANDOM ACCESS MEMORY(RAM)



DD R 2 SD R AM:

DD R

2 SD R AM stands for double data rate 2 synchronous dynamic random access memory.DD R 2 is twice as fast as DD R which means twice

as much data is carried to the module for each clock cycle.

Also due to the design improvements DD R 2 consumes less power as

compared to the DD R memory.

DD R 2 speeds range between 400 MHz (DD R 2-400) and 800 MHz (DD R 2-800).

DD R 2-400 transfers 3200 M B /s. DD R 2-800 transfers 6400 M B /s.

DD R 3 SD R AM:

DD R 3 SD R AM stands for, double data rate 3 synchronous dynamic random access

memory. I n theory DD R 3 is supposed to act twice as fast as DD R 2 memories.

Thus DD R 3 speeds range between 800 MHz (DD R 3-800) and 1600 MHz (DD R 3-

1600).

DD R 3-800 transfers 6400 M B /s; DD R 3-1600 transfers 12800 M B /s.

cable

VGA(Video Graphics Array) Port ² For projectors, monitors etc.



HARD DISK

Definition: A hard disk drive (HDD) is a non-volatile, random access device for

digital data. I t features rotating rigid platters on a motor-

driven spindle within a protective enclosure. Data is magnetically read

from and written to the platter by read/write heads that float on a film of air above the platters.

VISUAL FEATURES OF A LAPTOP

Screen Size - Size of diagonal screen in inches Eg, 10.1µ, 14µ etc.

Screen Type - LCD, LED , HD ready, 3D² Technological Advances in

Screens.

Screen R esolution - Maximum resolution it can support ( clarity indicator )

Graphic Memory ² I ndicates what is the Graphic Card used in the laptop

Example of a popular Graphic Processor - NVidia Graphic Card, AT I .



MULTIMEDIA ACCESS

Web camera :VGA - 0.3 Megapixel & 1.3 MP

Speakers ² Sony, HP ² Alteclancing, Dell ² J B L in XPS

Headphone Jack ² Standard 3.5 MM jack which fits all kinds of

headphones.

Mic - System Mic I nbuilt but also has a slot to connect an external Mic.

Dock Port - Docking Station Port ² to connect the system to a docking

station , looks neat , has more US B ports , Ergonomic.



BATTERY A laptop battery in new condition typically stores enough energy to run

the laptop for three to five hours, depending on the computer usage,configuration and power management settings. When the laptop is

plugged into the mains, the battery charges, whether or not the computer

is running, with the exception of some laptops.

Basically 6 Cell and 9 Cell



BATTERY TYPES

There are three different laptop battery chemistries. Nickel cadmium was the first chemistry, which was followed in time by nickel metal hydride and lithium ion battery

Nickel Cadmium (NiCad) NiCad batteries were the first rechargeable batteries for notebook computers and featured

low cost, versatility and high output current capability. NiCad batteries can be

charged rapidly and used in a wide range of products. However, they are now being designed out of notebooks in favour of the newer and higher power NiMH and Lion

batteries. Nickel Metal Hydride (NiMH)

NiMH batteries represented a significant improvement over NiCad batteries due

to improvements in cost, safety, reliability and capacity. Currently the most widely used notebook battery, the NiMH battery has only one drawback. The "memory effect" of NiMH batteries requires that they be fully discharged prior to

recharging for maximum charge effectiveness.



Lithium I on (LiON)

LiON batteries are now the most popular notebook battery because of

improvements over NiMH in the area of memory effect. I n addition, for batteries of comparable capacity, LiON batteries are generally somewhat

lighter in weight than NiMH batteries. B ecause the LiON chemistry is

the newest in the market and offers these benefits, the market price for

LiON batteries is often significantly higher than for NiMH batteries

with the same actual capacity.
