Laptop computers started as very expensive options for those who travelled on business and were willing to carry almost ten pounds of machine to be able to use a computer on the road.
Move forward in time, and you’ll find that laptops have become a much more affordable,portable, and ubiquitous option that many are choosing as their only computer, whether they travel much or not. If you’re thinking about joining the laptop revolution, it’s time you understand the advantages a laptop can offer.
The fact is that when it comes to performing computing tasks, a desktop and laptop are pretty much identical. They both have an operating system such as Windows 7 or Mac OS X. They both contain a hard drive where you store data and computer chips that process data, and they both run software and access the Internet.
Where a desktop and laptop differ is their physical appearance, size,and weight. Here’s a rundown of the key differences:
➟ Appearance: A desktop computer is typically encased in a tower into which you plug a separate monitor,keyboard, and mouse. (Though some newer models have the brains of the computer incorporated into a monitor base.) A laptop has all its parts in one unit. The central processing unit (CPU), chips, monitor, keyboard, and touchpad (a laptop version of a mouse) all fit in one compact package including ports for plugging in peripherals such as a transmitter for a wireless mouse or printer.
➟ Power source: A desktop computer is powered by plugging it into a wall outlet. A laptop contains a battery; you can run the laptop off of a charged battery, or plug the laptop into a wall outlet.
➟ Portability: Having a battery and coming in a more compact package makes a laptop more portable (though some larger models are a bit hefty to tote around); a desktop stays put on a desktop as a rule.
➟ Extras: Very small laptops might not include a CD/DVD drive and therefore require an external drive,to be attached.
