Many people use the computer every day at home or work, and some spend the bulk of their day sitting in front of a computer. Though the computer makes it much easier to communicate, find information and create documents and slideshows.

Communication

A personal computer provides you with the ability to stay in touch with hundreds of people. You can send emails and instant messages or video chat with a specific person for personal or professional reasons. If you want to send a message to many people at one time, you can write a blog or article or leave a post in a forum. Computers with a microphone are able to make free phone calls to landline or cell telephones. They can also send videos, photographs, songs, documents and audio files in just a few seconds.

Because of the Internet, most people are used to having information constantly at their fingertips. In just a few seconds, you can type a website URL into the search bar of your browser and visit a website full of information. There are online encyclopedias, books and user-submitted communities designed to provide specific types of information, such as video game walkthroughs. Offline, you can use digital encyclopedia software or play education games.

Fun

Computers provide a wealth of opportunities for fun and relaxation. You can play computer games, watch digital TV shows or movies, draw using a tablet and digital artwork software, create your own video or write a digital diary. However, computers often keep people from more traditional methods of having fun such as playing games with friends, reading books, watching TV or exercising. People with computers typically spend less time with their family and friends and may instead elect to communicate digitally, which does not provide the tone and body language required for effective conversation.

Increase your productivity

For example, once you have a basic understanding of using a word processor, you can create, store, edit, share, and print documents and letters. Each of these things was either impossible or much slower with all pre-existing technologies.

Connects you to the Internet

Connecting a computer to the Internet is what unlocks the full potential of a computer. Once connected, your choices and available options are almost limitless. Many of the benefits listed on this page are with a computer connected to the Internet.

Can store vast amounts of information and reduce waste

Computers are capable of storing and accessing vast amounts of information. For example, a computer and devices like eBook readers can store hundreds or thousands of books, given enough storage capacity. By being able to store books, documents, movies, pictures, and songs digitally, you can quickly find what you need with a search and share information between devices. It eliminates the need for paper and plastics used to make non-digital versions of the media.

Helps sort, organize, and search through information

A computer can use its stored information more efficiently than any other device. In our earlier example, we mentioned the ability to store thousands of books. Once those books are stored on a computer, they can be sorted into categories, alphabetized, and then searched to find exactly what you are looking for in less than a minute. Trying to find the same text in a thousand books would take a human months, if not years.

Get a better understanding of data

Computers can also give you a better understanding of data and big data. For example, a business could have a database of items they've sold. Using that data, they can quickly identify what sells best at what time of year, when to mark up or down items, and what items are not selling. Having access to this type of information can give the business a better understanding of their customers and a competitive edge against their competitors.

Keeps you connected

Computers can help keep you connected with long distance friends and family over e-mail and social networking. You can also connect with millions of other people that share the same interests as you through online forumschat, and VoIP services, like Skype. Being able to connect to people all around the world is also an excellent way to meet people you would normally never meet.
Another great thing about communication on the Internet is that it's fast compared to other forms of communication. For example, you could send someone an e-mail on the other side of the planet, and have it arrive in less than a few minute. Snail mail (postal mail) could take days or even weeks to arrive.

Can help you learn and keep you informed

The computer connected to the Internet is a great learning tool and something that helps answer almost any question, teaching you anything that interests you. You can also access news around the world to keep up-to-date with all of the latest news, weather, and stories around the world. You could learn a new profession by reading websites or watching videos. You could even sign up for online courses that teach you about any subject you'd learn in school.

Can make you money
