Long before the Internet actually existed, email or electronic mail, could be traced back to the directories of a new computer system used at the Massachusetts Institute of Technology in 1965. They had built a machine called “Compatible Time-sharing System” and eventually allowed university students and other registered users from around the New England States to share and store files on it. Students and faculty could login and store files on MIT’s IBM 7094 computer (See Figure 1). I was here
E-mail is short for Electronic Mail, a software application based on communications to transmit messages over the Internet as a communication network. The E-mail becomes the most popular and frequently used application because of the reasons of easily message transmission to the receiver even though the distance location of the sender and receiver within a thousand miles. Most of e-mail systems consist of an elementary text editor for composing messages, but many allow users to edit the messages
An Explanation of How the Internet Works Have you ever thought how the Internet works? The research found here will help answer that question. The Internet is a complicated system. There are two main protocols that the Internet uses that allow you to transmit and there are certain procedures that allow you to receive information via the Internet. The Internet is very large and many things have to work correctly for information to get to your computer or to get from your computer to someone
The Internet (Net) is a network of networks, connecting millions of computers together worldwide. It provides new ways of accessing, interacting, and connecting with people and content. It delivers packets of information similar to a postcard with a simple address on it, anywhere in the world. If you put the right address on a packet, and give it to any computer which is connected as part of the Net, each computer would figure out which cable to send it down next so that it would get to its destination

In view of emergence in cloud computing and cloud based identity management providers, the need for implementing SAML protocol is imperative. In addition, with the proliferation of SaaS (Software as a Service), and other web based applications, identity management has become challenging for various enterprises. Handling so many usernames and passwords for your intranet,
Networking Protocols for Different Applications How does one get two computers to interact with each other? By using a network. A network allows two or more computers to exchange data over a medium. Rules are needed so that the computers know how to communicate. These rules for the language computers use to transmit information are called protocols. As with the many different languages people around the world use to communicate, there are many different protocols. Some of these protocols include
Session Initiation Protocol Introduction Session Initiation Protocol (SIP) is a signaling protocol used for establishing multimedia communication session over an Internet Protocol (IP) network. SIP was originally designed by Mark Handley and Henning Schulzrinne in the year 1996. Latest version of SIP is specified in RFC 3261 from the Internet Engineering Task Force (IETF) Network Working Group. SIP is a request response protocol i.e. it deals with request from clients and responses from server
end communication control. 3) Network: Routes the information in the network. 2) Data Link: Provides error control between adjacent nodes. 1) Physical: Connects the entity to the transmission media. In simple terms, the OSI model defines a networking framework for implementing protocols. Is defines seven levels to accomplish this. Control is passed from one level to the next, starting at the Application level (Level Seven) and working its way through the levels until it reaches and completes
UNDERSTANDING THE OSI MODEL AND THE RELATIONSHIP WITH TCP/IP The Open Systems Interconnection (OSI) model is a reference tool for understanding data communications between any two networked systems. It divides the communications processes into seven layers. Each layer both performs specific functions to support the layers above it and offers services to the layers below it. The three lowest layers focus on passing traffic through the network to an end system. The top four layers come into
to the development of various protocols suited specifically to this task. Within the last five years, businesses have begun to need to share data across wide areas. This has prompted efforts to convert principally LAN-based protocols into WAN-friendly protocols. The result has spawned an entire industry of consultants who know how to manipulate routers; gateways and networks to force principally broadcast protocols across point-to-point links. Frequently the protocol of choice has been TCP/IP which
Internet and Its Services Working with Internet does not mean just browsing www and sending and receiving e-mails. The Basic Structure of the Internet was developed through last 30 years of existence of the Internet. The Internet is a heterogeneous worldwide network consisting of a large number of host computers and local area networks. The Internet uses the TCP/IP suite of protocols. This allows the integration of a large number of different computers into one single network with highly efficient
The transmission of words, sounds, images, or data in the form of electronic or electromagnetic signals or impulses. Transmission media include the telephone (using wire or optical cable), radio, television, microwave, and satellite. Data communication, the fastest growing field of telecommunication, is the process of transmitting data in digital form by wire or radio. Digital data can be generated directly in a 1/0 binary code by a computer or can be produced from a voice or visual signal
Internet service providers (ISP) are companies that would give user’s access to the internet, by providing them with the necessary equipment, like routers. This lets people use email, browsers and the worldwide web. People who use the internet at home will pay the ISPs a fixed amount of money a month so they have constant access to the internet. Business users will either pay a monthly or yearly and will have a much stronger connection because they normally pay a lot more. ISP’s will give you access
the network. The Internet, namely wide area network, local area network and single machine according to a certain communication protocol make up the international computer network. The Internet is the result of two or two more computers' terminals, the client and the server through the computer information technology means to connect with each other, people can send mail to thousands of miles away friends. completing a task and play games together. Network first appeared in the 1950s. In the 1950
Operating System Proposal Linux has long been one of many operating systems that have been out to prove its worth in all types of environment. It is currently being considered for enterprise network purposes as well as data centers where it implies servers, workstations and any mainframes as needed. Choosing what operating system to use, whether it is open source or not, can be difficult, though. This paper projects the advantages and concerns of choosing an open source solution like Linux as
you install on two PCs that permits one system (the guest) to connect with and control another (the host). Once you're connected, you can do just about anything as if you were sitting at the host PC. In addition, remote-control software lets you transfer files between PCs faster and more efficiently. The latest remote-control programs support a myriad of connection types including Internet connections, which are becoming increasingly important. The key advantage to Internet connections is that they

The Facts Today the internet is bigger than ever, four websites are created every second, traditional mail is being replaced with email, businesses are handing out less brochures and paper and putting the information on the internet instead, etc. The public is connecting in record numbers: about 75 000 users join the internet every day. In early 1996, more

Users can also use the LAN to communicate with each other, by sending e-mail or engaging in chat sessions. LANS are capable of transmitting data at very fast rates, much faster than data can be transmitted... ... middle of paper ... ...h the Internet.

The Internet: Today's Communication Revolution In the past decade, the Internet has emerged as the newest of communication media. It gives users quick access to information from around the world. People can chat with friends, read up to the minute news, and find samples of other media, such as music, movies, and books. However, the Internet required the construction of a considerable foundation before it became the information clearinghouse that is today. It is difficult to pick a particular
