Laptops are small mobile
computers that are light and portable enough to fit on your
lap. They weigh usually in the range of 4 to10 pounds
depending on the materials, size and other factors. When
compared to the PC Desktop, the portable laptops are
different on the basis of peripherals and weight. A typical
portable laptop computer has a weight of four to five
pounds. Some bulkier laptops range in their weights from six
to seven pounds as they may have a CDROM/DVDROM or a floppy
drive.
Laptops operate typically on a single battery and function
similar to their desktop counterparts as the basic
components of laptops and desktop computers are same.
Laptops have liquid crystal (LCD) displays and uses
different RAM modules. A portable notebook or laptop is
provided with a pointing stick or touch pad and built-in
keyboard as an input device. You can also plug in an
external mouse. The power consumption and noise are less
compared to a desktop. Unlike desktops, laptops can be run
on batteries also.

of 25 lines and 80 characters, a removable keyboard and a
floppy drive of 3.5 inches.

Ultra-Mobile PCs are small in size and portable. Ultra
portables have LCD screen of about 12 inches or less,
weighing about 3 to 5 pounds. Thin-and-light Laptops
typically weigh about 4 to 6 pounds and have a screen size
of 12 to 14 inches. Mainstream Laptops have a screen size of
about 14.1 inches to 15.4 inches and weigh about 5 to 7

Laptops have proven to be useful in many ways. While on the
move, from students to business executives, software
professionals and housewives have found laptops to be
beneficial. Laptops are available across a wide range of
brands, models, sizes, styles and prices. As the innovative
laptops have increased in demand, leading notebook
manufacturers such as IBM, HP-Compaq, Dell, Acer, Sony and
Toshiba are offering sophisticated laptops with innovative
features and designs. As the demand for laptops has
increased, you should be careful when choosing a laptop. You
can look for reviews on laptops from online sources and the
manufacturers also provide the information on the various
models available with details of prices, specifications and
ratings on their websites.
Laptops have to be chosen based on the features such as
Portability, Price, Screen size, speed, memory,
upgradeability, hard drives, batteries and hardware. You can
go for a laptop with a better screen resolution of 1024 x
768 XGA or 1280 x 1024 SXGA. For getting best performance in
terms of speed, laptops can be chosen having memory
capacities of 128MB, 256MB, 512MB or 1GB of RAM, depending
on your use of application. For occasional typing and web
surfing, a laptop with a memory of 256 MB RAM is sufficient.
You need to also check for lithium batteries as they offer
longer life. Other peripherals such as standard floppy or
DVD drives are required. Though laptops are expensive than
desktop computers for similar configurations, the price tag
is not big when compared to the functions they offer.
