What is a Network?
The network is a series of computers and devices linked together, often wirelessly, by means of communication devices and transmission media. Once a computer connects to a network, it’s online. Networks allow computers to share resources, such as hardware, software, data, and information. The sharing of resources saves time and money.
The Internet is a global array of networks connecting millions of companies, government agencies, educational institutions and individuals. More than one billion people around the world use the Internet every day for a number of purposes, including: to connect with and meet other people; to perform research and access a wealth of information and news; to shop for products and services; to bank and invest; to take classes; to access sources of entertainment and recreation, such as travel guides, online games, music, videos, etc.
Citizens are linking to the Internet to share information with others around the world. Email helps you to send messages to other people. You can have a live chat with another linked user with instant messaging. In a chat room, you can connect with several users at the same time — just like a group conversation. You may also use the Internet to make a phone call.
These are usually known by network addresses, which can include hosts such as personal computers, phones, which servers, as well as networking equipment such as routers and switches. Two such devices can be considered to be networked if one device is capable of sharing information with the other device, whether or not they have a direct link to each other. In most cases, application-specific communication protocols are stacked (i.e. carried as payload) over other more general communication protocols.
Businesses, called service providers, provide access to the Internet free of charge or for a fee. Through subscribing to an access network, you can use your computer and a modem to connect to a wide variety of Internet services. The Web, short for the World Wide Web, is one of the most popular services on the Internet. The site includes billions of documents that are called site pages. A web page can contain text, graphics, audio, and video. Web pages often have built-in links or links to other documents, graphics, other Web pages or Web sites.
What is the Website?
A web site is a list of related web pages. Some websites allow users to access music and videos that can be downloaded or transferred to storage media on a computer or portable media player and then listen to music through speakers, headphones or earphones, or view videos on a display screen. Anyone may create a web page and then make it accessible to others or post it on the Web.
Millions of people around the world enter online groups, each called a social networking website, which allows participants to share their interests, thoughts, stories, images, music, and videos with other registered users. Hundreds of thousands of people today are also using blogs to publish their thoughts on the internet. A blog is an informal website consisting of time-stamped posts in a diary or journal style, typically in reverse chronological order. Podcasts are a common way for people to verbally exchange knowledge on the Internet. A podcast is recorded audio stored on a web site that can be downloaded to a computer or to a portable media player such as an iPod.
