A computer is an electronic device used to process data and perform calculations. It can be defined in five ways: • Input/Output – A computer takes input from a user, processes it, then provides output for the user.

• Memory – A computer stores programs and data using RAM or ROM memory chips. • Processing – Computers use their central processing unit (CPU) to interpret instructions from software programs. • Storage – Data stored on a hard drive or other storage medium is accessible by the computer’s CPU when needed.

• Networking & Communication – Computers are connected to each other via networks that allow them to exchange information with one another over long distances. In summary, computers are complex devices capable of performing numerous tasks involving data manipulation and communication between users and computers alike.

What are the 4 Types of Computer?

Computer technology has evolved significantly over the past decades, with four main types of computers available today. These are: • Desktop Computers: These are larger than laptops and typically used for personal use or in a business setting.

They offer more power and storage capacity than laptops but tend to be less portable. • Laptop Computers: Portable computers that can be taken on the go, offering convenience and portability without sacrificing too much computing power or storage space. • Tablet Computers: Smaller devices that feature touchscreens, allowing users to interact directly with the device rather than through traditional keyboard/mouse interfaces.
