Networks and Websites.
Steve Jobs once stated, "What a computer is to me is the most remarkable tool that we have ever come up with. It's the equivalent of a bicycle for our minds (Griggs)." Computers and the Internet are full of exciting things, but it takes a lot for something remarkable to happen. There are so many opportunities available on the Web, but first there needs to be a connection. Networks such as LANs or WANs need to be available, then the Internet needs to be connected to a network, and finally it is time to search and enjoy the best Web sites in the world.
A network is a collection of computers and devices connected together wirelessly, generally used to share resources, exchange files, or allow electronic communications (Shelly). Computers may be connected to a network by cables, telephone lines, radio waves, or satellites. In order for a computer to be online and work, it needs to be connected to the network. The two most common networks are known as a local area network (LAN) and a wide area network (WAN).
Although these two networks are used for the same thing, they are very different. A local area network (LAN) is used for a small area. The most common places it is used is a home, school, office building, or a group of buildings could also be connected to one (Groth). A local network is useful for sharing resources like files, printers, games or other applications. Being able to share resources is beneficial because it will save money. For example, instead of buying a printer for everyone in an office, it is possible to hook several up to the same one.
The other kind of network is called a wide area network, also referred to as a WAN. This type of network is used across regions, countries, or the whole ...

To attempt to define a network in a few sentences would be a fool’s errand. A network could be seen as simply a grid of interconnecting connections between multiple bodies. However when this vision is applied to real-world systems, they all start to differ. There is not anything that exists in the universe that is not part of a network. A network is the result of different parts or members which have similarities in parts of their identity. This similarity that they have in common, they will also have with other bodies forming a network between them. Most of these factors of identity are different from those of most others. As a result, each factor will be in common with different other members of different networks. Each factor includes this body in a multitude of networks. This means that no one thing is in one and only one network, but is included in many.
Wired Networks are also called Ethernet Networks. A wired network in its simplest form is a collection of two or more computers, printers and other devices linked by Ethernet cables. Ethernet as a fastest protocol in a wired network offers connection speeds of 10 megabits per second (Mbps) or higher. Wired networks can also be participated in other wired or wireless networks. When a computer want to connect to a network, initially the computer must have an Ethernet adapter (sometimes called a network card, or NIC).
They are all Local Area Network (LAN) technologies or standards for communication across different medium. In the past decades the essence of internetworking has vastly increased. As always, demand breeds supply, and several different LAN technologies have emerged. LANs can be implemented in several ways. They can be divided into several subgroups based on e.g. physical implementation or standardized technologies. Choosing the right kind of LAN solution for a particular purpose always depends on several issues, e.g. size of the network, location of the terminals, and cost. Let us look a little deeper in the details.
LANs systems can be defined and connected in many different ways. This is the reason for the standardization for every one can have a common ground to start from. “The LANs described Herein are distinguished from other types of data networks in that they are optimized for a moderate size geographic area such as a single office building, warehouse, or a campus. The IEEE 802 LAN is a shared medium peer-to-peer communications network that broadcasts information for all stations to receive. As a consequence, it does not inherently provide privacy. The LAN enables stations to communicate directly using a common physical medium on a point-to-point basis without any intermediate switching node being required. There is always need for an access sublayer in order to arbitrate to access to the shared medium. The network is generally owned, used, and operated by a single organization. This is in contrast to Wide Area Networks (WANs) that interconnect communication facilities in different parts of a country or are used as a public utility. These LANs are also different from networks, such as backplane buses, that are optimized for the interconnection of devices on a desk top or components within a single piece of equipment.”(IEEE 802 Standard 1990) That is the standard definition for LANs by Institute of Electrical and Electronics Engineer committee 802. They are the committee used to set the standard in workmanship and operations for technicians that set-up and perform maintenance on LANs systems. And through all the technical words what they are trying to say is a LAN is a small area network that distributes information among computer in a small work environment unlike WANs that distribute information across global areas.

For my independent study, I have created a network in my house. A network by definition are more than one computer that are linked together electronically via a protocol (common language) so the computers can communicate and share resources. This network improves the day-to-day life by adding value and usefulness to the computers. The processes and ideas that I have learned thru this experience can be applied directly into today’s rich electronic business environment.
When one gets on the Internet they are exposed to everything the Internet can give them. They can chat with people from all over the world, view the thousands of files, and send electronic mail. The possibilities of the Internet are endless.
Exploring The Internet The Internet is like a network of networks where any computer can link up to information stored within it. It is accessed by a telecommunications line and a modulator-demodulator (MODEM). It is brought to your computer screen by converting analogue telephone signals into digital computer signals. There are many advantages and disadvantages on the Internet.
In our society, there has been a revolution which competes with that of the industrial revolution. It is called the technological revolution. At the top of the technological revolution is what we call, the Internet. In the following report we will be discussing what the internet is about in general and how it might be in the future, why it is necessary in our everyday lives, and why it has become so important to everyone. companies, individuals ).
The Internet has revolutionized the computer and communications world like nothing before. The Internet enables communication and transmission of data between computers at different locations. The Internet is a computer application that connects tens of thousands of interconnected computer networks that include 1.7 million host computers around the world. The basis of connecting all these computers together is by the use of ordinary telephone wires. Users are then directly joined to other computer users at there own will for a small connection fee per month. The connection conveniently includes unlimited access to over a million web sites twenty-four hours a day, seven days a week. There are many reasons why the Internet is important these reasons include: The net adapts to damage and error, data travels at 2/3 the speed of light on copper and fiber, the internet provides the same functionality to everyone, the net is the fastest growing technology ever, the net promotes freedom of speech, the net is digital, and can correct errors. Connecting to the Internet cost the taxpayer little or nothing, since each node was independent, and had to handle its own financing and its own technical requirements.
The Internet is a network of networks, linking computers to computers sharing the TCP/IP protocols. Each runs software to provide or "serve" information and/or to access and view information. The Internet is the transport vehicle for the information stored in files or documents on another computer. It can be compared to an international communications utility servicing computers. It is sometimes compared to a giant international plumbing system.
The Internet has made access to information easier. Information is stored efficiently and organized on the Internet. For example, instead of going to our local library, we can use Internet search engines. Simply by doing a search, we get thousands of results. The search engines use a ranking system to help us retrieve the most pertinent results in top order. Just a simple click and we have our information. Therefore, we can learn about anything, immediately. In a matter of moments, we can become an expert.
Mesh networks are reliable, stable, and redundant. If a node can no longer operate, all the others are not affected as they can still communicate either directly or through one or more intermediate nodes. Mesh networks can be very expensive due to the large amount of cable and connections required. Bus Topology Bus topology refers to a local area network (LAN) arrangement where each node or device is connected to a main cable or link called a bus. The bus network is simple yet very reliable.
The Internet is one of the greatest inventions of humanity. It is a massive network of computers, each with the ability to access any of the others. Ungodly amounts of information can be found on the Internet. It is the ultimate form of media, a combination of newspaper, radio, and as the average bandwidth is increasing, television. Using
“Wide area networks are used to connect local area networks together, so that users and computers in one location can communicate with users and computers in other locations. Many WANs are built for one particular organization and are private, others, built by Internet service providers provide connections from an organization’s LAN to the Internet.” WANs are usually built with leased lines from different telecommunications companies. At the end of these lines is a router which allows access and transmissions through these given lines. Through various telecommunications devices and services wide area networks are the leading technology in transmitting global information and communication. “The main purpose of a WAN is to provide reliable, fast and safe communication between two or more places with low delays and at low prices.”
