A Bit Behind Technology? Know Everything About Laptop Computers

From offices to schools and even at homes, laptop computers are definitely a huge part of everyone’s lives. And important as they are, a little understanding of these useful and popular gadgets would definitely prove as a great asset.

Laptops serve as a mobile replacement for desktop computers which are virtually stationary and bulky. Most functions, applications and components of laptops and desktop computers are the same. Perhaps, the greatest advantage that a laptop could offer is its portability; one can easily bring and use a laptop anywhere.

Internal and External Components

The components of laptops are basically the same with desktop computers. The only difference is, of course, laptop parts are made smaller to conform to the gadget’s promise of portability.

* Central Processing Unit (CPU)

CPUs designed for laptops are usually less powerful than their desktop counterparts are. However, they also present useful features such as power-saving.

* Expansion Cards

Expansion cards are essential components of laptops since they permit the changing of a laptop’s functionality. Some of the most common types of expansion cards include MiniPCI and PCI Express Mini.

* Battery

Laptop batteries are rechargeable Lithium-Ion models which can typically last for approximately 8 hours. Nevertheless, recent breakthroughs in technology launched laptop batteries which can work for a maximum of 24 hours when fully-charged.


Laptop RAMs are usually placed on the bottom part of the gadget for easier access when the owner wishes to upgrade the laptop memory. A vast majority of RAMs today feature a 4GB memory, which is enough for office or home use.

* Internal Storage

Hard Disks allow people to store various types of files such as documents, games, pictures and any other applications into their laptops. While most hard disks are small, ranging from 46 to 64 millimetres in size, they can actually store up to 500 GB.

* Power Supply

A laptop contains a rechargeable battery which can be charged by connecting an AC cable to the external power supply. The power supply usually has a DC voltage of about 14.8 volts.

* Display

CCFLs and LED displays are some of the most common types of laptop screens used by computer manufacturers. These screens vary in their sizes; some come in bigger 15″ displays while others can be as small as 13″.

What are the Types?

* Netbook

Netbooks are those smaller, thinner and lighter types of laptops which can fit even in miniature bags. Netbooks are also cheaper than full-size laptops. However, they also provide a limited number of applications and functions. For example, netbooks do not have CD drives, therefore preventing the owner to watch movies or play videos with CDs.

* Desktop Replacement

Desktop replacement laptops are intended to feature all the functions of a desktop computer. Hence, they tend to come in bigger sizes. Most full-size laptops are available in 15″ displays.

* Rugged

Rugged laptops are specialized laptop computers which are devised to adapt in rough conditions like scratching, vibrations or wet surroundings. Reasonably, their parts are also well-protected; the keyboards have rubber sheets while the USB ports are covered with frames.
