3. INFORMAITON ON LAPTOPS
A laptop is a portable personal computer with
a clamshell form factor, suitable for mobile use.[1] A
laptop has most of the same components as a
desktop computer, including adisplay, a keyboard, a
pointing device such as a touchpad (also known as
a trackpad) and/or a pointing stick, and speakers
into a single unit. A laptop is powered by mains
electricity via an AC adapter, and can be used away
from an outlet using a rechargeable battery.
4. Laptops are also sometimes called notebook
computers or notebooks. Other terms, such
as ultrabooks or netbooks, refer to specific types of
laptop / notebook. Most of the modern day laptop
computers also have a webcam and a mic (microphone)
pre-installed
5. Portable computers, originally monochrome CRT-based and
developed into the modern laptops, were originally
considered to be a small niche market, mostly for specialized
field applications such as the military, accountants and sales
representatives. As portable computers became smaller,
lighter, cheaper, and more powerful and as screens became
larger and of better quality, laptops widely used for a variety
of purposes.
