Units of Measurements
In a computer there are several factors that determine how efficient a computer or a laptop is. Among them is;
Storage; this is the space of storing your content. In a computer storage is measured in gigabytes (GB).
Speed; this measures how first computer processor (CPU) is. Speed is measured in Hertz (Hz) but Hertz is to small and therefore in a computer gigahertz (GHz) is used to measure speed.
Points to note
When one is buying a computer or a laptop, what is important is RAM, speed and Storage. For a desktop computer or laptop the RAM should not be less than 2GB. If the RAM is less than 2GB it means the computer will not allow you to install some softwares (applications or programs) that require a minimum of 2GB. Also, RAM in a way determines whether your computer is slow or not. It is good to know that you can upgrade the RAM.
For a desktop computer the speed should not be below 2.9GHz. For a laptop it should not be below 2GHz (a good laptop should be between 2GHz and 2.6GHz). Speed cannot be changed. If you see a computer or a laptop that is too slow, first check its speed.
Computer or laptop storage is determined with what one want to store. But, a minimum of 500GB is not bad. If one want to store movies then more storage space will be needed.
Classifications of computers

Classifications of computers
Computers are grouped according to:
- Size (size overlaps among all computers)
- Power (RAM, speed and storage)
Other classes of computers are workstation, mini computers, main frames and super computers. These computers are used in an environment that require high speed, RAM and storage. For example, research centers, major hospitals, census bureaus, electoral bodies and so forth.
Other classes according to size include laptop, netbook, smartphones, mobile devices and tablets. These devices are capable of storing charges and therefore in case of electricity interruptions one can continue working normally and they are portable.
