At home, computers can be used to find information, store various data like pictures, music and videos, track finances, play games, communicate with other people around the world via the internet and much more. With Internet access, you can communicate with people all over the world and find a vast amount of information.

 

What is web?

The World Wide Web (usually called the web, or web) is a vast storage of information. The web displays most of the information in a visually delightful format, hence the reason for its popularity. Headlines, text, and pictures can be combined on a single webpage; similar to the pages in a magazine, along with sounds and videos. A website is a collection of interconnected webpages. The web contains millions of websites and billions of webpages, and millions of websites are uploaded each day.

Exploring the web is known as Surfing. Anyone surfing the web can find information about almost anything or any topic imaginable. You can read news or stories and movies reviews, book a hotel or an air ticket, view maps, get current weather and future weather forecast, view pictures or videos, play games or read the game reviews, etc. Almost all the companies, agencies, libraries and museums today have their own websites with information about their products and services or collections. You can also search and purchase products online - books, music, toys, clothing, electronics, and much more. You can also buy and sell used items through websites that use auction-style bidding. For example, see this website.

 

E‑mail

E‑mail (Electronic mail) is an electronic means of sending the letter to someone. When you send an e‑mail message, it arrives almost instantly in the recipient's e‑mail inbox. E-mail messages can be sent to many people simultaneously,  and you can save, print, and forward the e‑mail to others. You can send almost any type of file in an e‑mail message; documents, pictures, music, videos etc. And with e‑mail, you don't need a postage stamp (how cool is that!!).

 

Instant messaging

Instant messaging is having a real - time conversation with another person who is far away from you. When you send an instant message, the message is immediately visible to all participants of the conversation. Unlike e‑mail where the message is delivered at any time and the recipient may view it at anytime, for instant messaging, all participants of the conversation have to be online (connected to the Internet) and in front of their computers at the same time. Communicating by means of instant messaging is also known as chatting.

 

Pictures, music, and movies

If you have a digital camera, you can move your pictures from the camera to your computer. Then you can print them, create slide shows, or share them with others by e‑mail or by posting them on a website. You can also listen to music on your computer, either by importing music from audio CDs or by purchasing songs from a music website. Or, you can tune in to one of the thousands of radio stations that broadcast over the Internet. If your computer comes with a DVD player, you can watch movies too.

 

Gaming

Everybody likes to play games. There are thousands of computer games in every category imaginable, which you can play on your computer. Get behind the wheel of a over-speeding car, battle frightening monsters in a dungeon, or control civilizations and empires! Many games allow the users to compete with other players around the world via the Internet.
There are also some games which can be played online only - called online games. Such games can be played with the computer or with other opponents from around the world. You can also earn money from these games if you win or even if you are close to win!




Web hosting strategies

 Various web hosting companies have different kinds of offers for their clients, that differ in price and the offered service as well as the quality of the service. Some of the important points about web hosting strategies are discussed below.

  • The web hosts provide a place for storing the web pages so that they can be viewed online from anywhere.
  • The hosting company can be anywhere around the world.
  • There are two sectors of hosting companies like everything else - one that is cheap but with poor quality of service, and the other somewhat expensive but promising more prompt and quality service.
  • Cloud hosting is another important development step in web hosting that allows to share not only the web pages but also the programs that are too big to keep in personal computers.





Web Hosting

What is web hosting?
A web hosting service allows an individual and/or organization to make their websites accessible through the world wide web (WWW). The companies that provide the space on a server they own are known as web hosts, who provide the web hosting service. Web information is stored in documents called web pages, which are stored on computers called web servers; and the computers reading the web pages are called web clients.

Hosting your web site on your own server is always an option. Following are some of the points that can be considered:

Hardware
Running a real website needs some powerful server hardware that cannot be replaced by a low cost PC. You'll also need a permanent source of power supply (so that the website is not down if there is load shedding or other power problem) and a permanent high-speed connection.

Software
Server-licenses usually have limits on number of users, and they are often higher than client-licenses.

Labor
Installing your own hardware and software cannot be accomplished with low labor expenses. Also bugs and viruses need to be dealt with, and the server needs to be running constantly in every situation.
