Personal Computer (PC)

What is Personal Computer (PC)?

Personal Computer or PC refers to the digital computing system that is built to be used by one person only at a time. It typically runs on commercial software applications and operating systems or open source and freeway software.

Technically, this is a device that is much smaller in size but has everything to make it a multi-purpose computing machine that can be operated directly by the end user, whether a computer expert or a beginner.

A Personal Computer is made of a few specific parts which are:

In addition to these basic components, the PCs also come with a network or internet connection, and several different ports to connect the different peripheral devices.

This is all about the hardware of the computer that is required to set it up or build it. However, in order to make it work, you will also need suitable software and drives such as the operating system.

It can do anything, well almost, that a large computer can do. And, the working process is also quite similar which involves:

Furthermore, using the internet too much may also result in its addiction which may also affect your health, performance at work or school and you may even get involved in cyber crimes or be duped.

In short, this is a beneficial technology that is most favored by the users and is virtually indispensable today that has made their lives easy.

The most significant benefit offered by a PC to the users is that it lets them save time and effort as well as money while performing any task in more than one way, no matter whether it is used by a beginner, an expert, a school going kid or a housewife.

Personal Computer History

Though the initial effort was made by Microsoft to tread the uncharted terrain of the PC industry, history says it did not start with IBM or Microsoft.

Historically, this is the timeline of the personal computers:

Since then several companies made improvements in their existing products and a few even came up with newer models till 1994 when the personal computers became more than just a computing machine – a gaming PC.

Once again different companies took part in the race and came up with newer and more powerful models such as:

Further, with the launch of the low cost Celeron CPU by Intel in 1998, new generation PCs were created by Apple such as Lombard, a light PowerBook with USB, in May that year.

In August the same year, Apple launched the Power Mac G4, one of the most powerful and strong computers of the world that fell under export restrictions.

In 2002, Apple introduced the flat-panel iMac G4 along with two other new PowerBook models of PowerBook G4 in January 2003 that were further fortified with a 5” aluminum model in September that year.

Apple also introduced Power Mac 970 in July 2003 using the newest PowerPC of IBM along with further upgrades done on it later on.

Finally, you have the popular personal computers of today, a field that is typically categorized between Apple Macintoshes and PCs.

Types of Personal Computer

A personal computer can come in different forms and shapes but the most commonly known forms are desktop computers and laptop computers.

However, there can be several subcategories of it such as a tablet, a microcomputer, a handheld system and more.

Here are the different types of PCs along with a brief description of each.

Desktop computers

This type of personal computer is most extensively and commonly used in different settings such as homes, offices, schools and others.

These systems are designed to be set up and stay in one particular place because they are usually large in size and heavy to carry from one place to another easily.

Since these computers sit on a desk or a table, it is called a desktop computer. It has more powerful components than other personal computers and can perform multiple tasks quite easily and efficiently.

The main part of this particular form of personal computer is the System Unit or the case that holds all the critical parts of the system that makes it work and typically comes in two specific models such as:

Laptop computers

This is the second-most popular type of personal computer that is extremely portable due to its light weight build and small size.

It can be used on the user’s lap and does not need to be connected to a power outlet continuously because it is powered by a battery.

Depending on the components inside the system, a laptop computer may perform at par with a desktop computer but will usually become hot much more quickly than the larger desktop variant.

Users can also plug in a laptop computer into a docking station, if the design permits, and include a full-size keyboard, mouse or other peripheral devices.

The docking station will offer additional ports that will allow the user to use the system just like a desktop computer connecting to different devices or a network.

Workstation computers

This is also a special type of a desktop computer but is built with more powerful components than it.

Apart from a powerful processor, the workstations are also equipped with additional memory, high-end graphics card and can perform at a much greater speed overall in comparison to a regular desktop computer.

These specific computers are usually used by and are best suited for professionals such as scientists, researchers, engineers, animators, and others who need to work on CPU and GPU intensive applications and programs such as game development, research work and 3D graphics designing.

Notebook computers

These systems are very much the same as the laptop computers but are much lighter and smaller in size.

Tablet computers

Referred to as tablets simply, these PCs come with almost the same features and functionalities of a notebook computer but are even further lighter and smaller in size.

Input can be given directly on the screen that recognizes touches of a special digital pen commonly known as a stylus.

Depending on the model and design, there may be additional features included in a tablet such as a built-in microphone and special software to receive voice commands of the user.

A tablet may even be connected to a network or converted into a full-fledged monitor, a keyboard, and even a notebook computer with the help of a book cover keyboard.

Handheld computers

These systems are so small in size that they can be used on your hand and can be carried in your pocket.

These are therefore often called a palmtop computer. A good example of these small computers is the PDA or Personal Digital Assistant which is not bigger than a small appointment book.

These smaller systems are good enough to take notes, maintain your telephone contact list, addresses, important dates and events.

A few systems, based on their design, may allow writing on the screen directly with a stylus or even sync it with a desktop computer for exchanging data. These systems may also come with other features such as:

Smartphone computers

It may sound strange but a smartphone is actually a computer but is less powerful. These systems are usually a combination of a cell phone and a PDA.

However, these specific devices come with more advanced features that are usually not found in regular cell phones and are therefore named smart phones.

A smartphone will allow you to do a lot of thing that you would do with a computer such as:

Features of Personal Computer

It is the features of the personal computers that make them so useful which include speed, reliability, accuracy, versatility, storage, automation and more.

Here is a brief explanation of each:

Examples of Personal Computer

A few examples of a personal computer, as mentioned earlier, are microcomputer, desktop computer, laptop computer, smartphones, tablets, palmtop computers, workstations and others.


This article surely has made you more knowledgeable about the basics and more about the personal computers. Though it is designed to be used by a single person and for personal use, a network can be created with it. In short, a personal computer is a device that has some benefits to offer to any type of user.
