The connection between Networks and the Internet - Essay Example

Teacher: Introduction In the center of the information age, modern daily lives depend on communication. The way weconverse has progressed through the years changing the means in which information is created and spread. This immense need for information has led to technological progresses and this have brought the world nearer, making lengthy remoteness shorter, permitting us to move to distant places faster and almost putting the entire globe at the palm. (LaQuey 34).Q.1 In a technology framework, a network can be described as interconnection of digital machines capable of sharing resources and information.

In a computer network, all data transmitted consist of a node which refers to any computer or digital device using the network links (Krol 49).Q.2The finest way to lead in the world of business today is to network systems in organization and businesses. Data networks are essential to all existing modern organizations. They facilitate in faster and easier ways to access any data and resources that are within the organization (Krol 53).Q.3There are many types of networks used in the entire world today both commercially and homes.

Networks cab categorized according to their scope and scale, historical grounds, favorites for networking industries, their design and implementation matter (Krol 59).LAN - Local Area Network- This type links networking devices which are within small geographical area like homes, office and cyber cafes. WAN - Wide Area Network - This network covers up a larger span for communication between the network devices. It is an interconnection of many LANs through routers, and its example is the network which is covering the entire globe.

MAN - Metropolitan Area Network - This type of set-up is not common, but it can be useful in governmental departments and large organizations such as banks. It falls at the middle of LAN and WAN. It covers a larger geographical coverage compared to Local Area Network but smaller than Wide Area Network.   CAN - Campus Area Network – This network interconnects several multiple Local Area Networks but smaller compared to a Metropolitan area network. This type of network generally can be useful relatively in vast universities or buildings and local business offices.

  SAN - Storage Area Network - This technology is mostly used for data storage. It’s mostly crucial to those organizations that are data oriented. This network connects servers to the data store devices through fiber channels technology. SAN - System Area Network - This network also identified as cluster area network. It connects high performance computers with extremely high speed connections in cluster configuration (LaQuey 58). Q.4A network topology illustrates the arrangement of machines and devices on a network.

It describes the way the computers and other devices within the network are laid down and linked to each other. Common network topologies used include;Star - One central device is joined to every other computer on a network. Ring - Each computer is connected to just two other terminals, and this forms a ring. It looks like a ring as it forms circular shape. It requires three nodes to form the ring topology.Line – The layout of the computers in this topology are joined up in a line format. Mostly computers are linked to two other.

Bus - Every computer is linked to a central bus that runs along the entire network. All data transmitted through the bus can be accessed by any computer within the network.Tree - One ‘Main’ machine links to every other node which in turn get connect to other nodes forming a tree like structure. Data from the root machine may have to pass through other machines to reach the end machine (LaQuey 60).Q.5 The internet is an immense network of many different interconnected networks globally and it’s easily accessible to the public.

These interlinked computers function by transmitting information through a unique type of packets switching which is generally known as the Internet protocol or IP. Q.6Internet is the most essential technology of the modern world. It has not only made the modern society easier than before, but it as well plays a highly significant role in the prospect development. Researchers can get any information they require and anyone looking for other services such as games or any form of entertainment can easily get the information. Q.7Internet can be looked at as a system involving two main components.

Hardware components that include any machine that transmits data. They include cables, routers, radio equipments, satellites, cell phone towers and other data transmission devices.Protocols are the other key component that facilitates the network communication. These are rules that governs machines to complete any task during data transmission. Without these sets of instructions, communication cannot happen because computers and other devices within the network would be unable to send any information in a meaningful manner (LaQuey 73).

ConclusionFrom side to side, a computers system that is physically many miles away is just near as a computer in the office next room. This concludes that any information that is obtainable thousands of miles far away from your computer is as near as what is on your system. This is one of the major, significant advantages of the network. Work sitedLaQuey, Tracy. Users Directory of Computer Networks. Bebford, MA: Digital Press, 1989. Print.Krol, Ed.
