I, Computer: Definition

A computer is a machine that can be programmed to manipulate symbols. Its principal characteristics are:

  • It responds to a specific set of instructions in a well-defined manner.
  • It can execute a prerecorded list of instructions (a program).
  • It can quickly store and retrieve large amounts of data.

Therefore computers can perform complex and repetitive procedures quickly, precisely and reliably. Modern computers are electronic and digital. The actual machinery (wires, transistors, and circuits) is called hardware; the instructions and data are called software. All general-purpose computers require the following hardware components:

  • Central processing unit (CPU): The heart of the computer, this is the component that actually executes instructions organized in programs (“software”) which tell the computer what to do.
  • Memory (fast, expensive, short-term memory): Enables a computer to store, at least temporarily, data, programs, and intermediate results.
  • Mass

anyone from a business person, to an artist, to a housekeeper, to a student -
an incredibly powerful and flexible tool.





Software is actually a computer program. To be more specific, a program
is a set of step-by-step instructions that directs

The Best Desktop Computers for 2020

How to Choose the Right Desktop PC

Why, given the advanced state of laptops, would you want to buy a desktop PC or Mac nowadays? Simply put: sheer muscle and computing comfort. Mobile devices like laptops and tablets simply can’t fill some computing needs as well as the stalwart desktop.

Desktop-class CPUs and graphics processors are more powerful than their mobile counterparts for the same money. They give you the grunt to finish whatever task you’re working on in less time. Your money goes further with desktop components in general, too, so instead of buying a $500 laptop with a competent Intel Core i3 processor, you can buy a $500 desktop with a more powerful Intel Core i5 desktop CPU in it and maybe even squeeze in a dedicated graphics card.

You can get desktops with screens that are already built in (see our guide to the best all-in-one PCs),
