It may seem a straightforward question with an obvious answer. But it’s a tough question because of the receding boundary between a computer and other ‘computer-like’ devices. Modern gadgets can do so many things like a computer. Therefore, many of us are not sure about the exact definition of a PC even though we use the term every day.

What is a PC? In today’s tech-savvy world, we often hear the terms “PC” and “laptop” used interchangeably. But are they really the same thing? What exactly defines a personal computer, and how do laptops fit into the equation? Let’s embark on a journey to unravel the mysteries of personal computing and understand the nuances that distinguish these devices.

What is a PC?

PC means personal computer. The term PC was coined by Ed Roberts when he introduced the MITS Altair 8800 in the 70s. Later, the word PC was popularized by IBM (International Business Machine Corporation). The first personal computer produced by IBM in 1981 was called the IBM PC. Later, many other companies started making computers by following the IBM technology. Those computers were also known as IBM PCs or IBM Compatibles. The term ‘IBM PC’ fell out of use because of varied manufacturers and diversified modern PCs.

A PC is essentially a computer that is designed for use by one person at a time. A computer is an electronic device that stores and processes data based on the instructions provided by a software or hardware program. Personal computers are made for general users. You can use a PC to browse the web, type documents, send an email, and play games. You can also use it to edit and create a presentation, spreadsheets, and videos.

Some people also use the term PC based on the operating system of a computer. There are two most influential OS in the market — Microsoft OS and Mac OS. If a computer runs on a Microsoft operating system, people call it a PC. Many people think a Mac is different from a Windows PC. The truth is, there isn’t much of a difference between Windows OS and Mac OS. Both are operating systems for personal computers. And, only operating systems don’t determine if a device is a pc or not. Then, what are the criteria for calling a device a PC?

What Makes a PC, a PC?

First of all, a personal computer is meant to be used by one person at a time. So, there is no confusion about the word “personal.” The problem lies with the word “computer.” What is a computer? Is a laptop, a tablet, or a smartphone a computer? To resolve all the confusion about the definition of a personal computer, I have figured out some basic features that every PC has. If a device contains all these features, we can call it a PC.

  • A PC has an operating system. It can be Windows OS, Mac OS, or even Android OS.
  • Personal computers have a microprocessor. It is the microprocessor that allows manufacturers to put an entire CPU on one chip.
  • Computers store data in their memory.
  • PCs have the ability to take input and produce output.
  • You can install software or apps on a personal computer.
  • A personal computer is designed to be used by one person at a time.
  • A PC can be any size. Size doesn’t matter. As long as it’s used by one person and has other main features of a computer, it’s a PC.
  • Personal computers have multitasking capabilities. That is, it can do many tasks simultaneously and efficiently.
