Laptop computers, also known as notebooks, are portable computers
that you can take with you and use in different environments. They
include a screen, keyboard, and a trackpad or trackball, which serves as
the mouse.
Because laptops are meant to be used on the go, they have a battery
which allows them to operate without being plugged into a power outlet.
Laptops also include a power adapter that allows them to use power from
an outlet and recharges the battery.
While portable computers used to be significantly slower and less
capable than desktop computers, advances in manufacturing technology
have enabled laptops to perform nearly as well as their desktop
counterparts. In fact, high-end laptops often perform better than low
or even mid-range desktop systems. Most laptops also include several I/O ports, such as USB
ports, that allow standard keyboards and mice to be used with the
laptop. Modern laptops often include a wireless networking adapter as
well, allowing users to access the Internet without requiring any wires.
While laptops can be powerful and convenient, the convenience often
comes at a price. Most laptops cost several hundred dollars more than a
similarly equipped desktop model with a monitor, keyboard, and mouse.
Furthermore, working long hours on a laptop with a small screen and
keyboard may be more fatiguing than working on a desktop system.
Therefore, if portability is not a requirement for your computer, you
may find better value in a desktop model.
To format a drive (hard disk, floppy disk, flash drive, etc.) means to prepare the chosen partition on the drive to be used by an operating system by deleting all of the data1 and setting up a file system.
In Windows, formatting a partition is usually done from the Disk Management tool. You can also format a drive using the format command in a command line interface like Command Prompt.
Upgrade is a to replace existing software or hardware with a newer version.
