laptop : Computer Hardware Buyers’ Glossary

laptop

Laptop computers are so compact you can carry them around.
The advantages of laptops over desktop computers are:

portability.
They work even when you don’t have access to power.
When they are plugged into the wall, they carry on working, even if there is a power outage or power dip.
It is harder for others to snoop on what you are doing by monitoring the radio waves your computer gives off.
They use less power than desktop computers.

The disadvantages of laptops are:

They cost about twice as much for the same computing power.
Spare parts are perhaps four times as expensive as for desktops. They may not be available since you cannot use generic parts.
The keyboards tend to be small with missing keys.
You have to look at the screen from a certain angle to see the picture. This makes it hard for two people to see the screen at once.
The flat LCD (Liquid Crystal Display) screens usually have lower resolution and brightness than desktop monitors.
Laptops are often missing floppy drives, CD-ROM (Compact Disc — Read Only Memory)s, large hard disks, sound cards or modems, things you take for granted in desktop computers.
They are not very expandable. Any expansion you do will require a part custom fitted for your particular model. This will cost you four times as much as a generic part.
They are much harder to service. You will have to take them to an authorised dealer for your model.
