Essay on Wide Area Networks

In this modern day and age of computing, networks are a huge part of IT. It is important now more than ever that data sent over any network, whether it be a LAN (Local Area Network) or WAN (Wide Area Network; The Internet) is kept safe, private (when required) and uninterrupted in

For correspondence between two PCs utilizing a serial interface or a PC joined by telephone line to a server.

Routers and switches will be utilized to route network signals to all areas of this large network. Telephony systems will be introduced to serve the VOIP located at each location to assist with communication needs. Wireless technologies will also be needed to assist with mobility and other devices such as printers, laptops, fax machines, etc. Lastly, a physical firewall will be enforced at each location to protect the network from internal and external intruders.

You will discover different network topologies and different types of networks: LANs, WANs, and internetworks (internets). The concept of switching is discussed to show how small networks can be combined to create larger ones. You will learn about the Internet: its early history, the birth of the Internet, and the issues related to the Internet today. This module covers standards and standards organizations.

Team “C” was hired by Riordan Manufacturing management to overhaul the security features currently employed by the company. Management outlined a comprehensive plan that included a complete hardware refresh, security best practices and end user training. Team “C” will devote resources to assess the physical and network security issues and concerns at each Riordan plant. Once those have been identified, Team “C” will identify the data security issues and concerns present at each Riordan plant. Finally, Team “C” will address web security issues and concerns present at each Riordan plant and recommend a way forward for the company.

WAN (Wide area network) WAN connects computers and devices within a wide area WAN is usually used in business to send data between employees, buyers, and suppliers from anywhere in the world. WANs standards are pretty much the same as LAN’s standards and protocols they are both on TCIP. IEEE 802.14 Cable modem, IEEE 802.6 MANs (DQDB), IEEE 802.7 Broadband LAN using Coaxial Cable ISDN and ASL broadband these are the standards for

The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was

contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers.

Something that really struck out to me was the topic of networking. In Chapter 2, author, Don Raskin goes into depth about the importance of networking. What Raskin says about networking really makes a lot of sense because it is much easier for companies to make hiring decisions based on recommendations from a trusted source than hiring someone through the interviewing process. Employers can get an idea of who the interviewees are, but having people recommended to them makes their job way easier. Networking is something that I will definitely do to my fullest when I look for an internship/job. Getting to know many influential people that will help me better my career will really set me aside from others. Having as many connections as possible

The internet operates under what is called the “end-to-end principle.” This is where “features are implemented as close to the end points of the network as possible.”4 It is often described as a “dumb network.” Much like how a water system provides the same amount to all users through pipes regardless of what its used for, only the end user decides and controls how a “dumb network” is utilized. Some claim that this is a major reason that the internet was so successful. However, it is also pointed out that internet is already not “a level playing field,” because of the advantages of bigger companies who can afford more robust servers and high-bandwidth services.1

Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.

Internet: Global network of networks using universal standards to connect millions of different networks (Kenneth C Laudon and Jane P Laudon., 2010).

Over the next 10 years, we will see a change in technology, and the Internet. Things will continue to progress, and fundamental changes will easily be defined. Technologies have revolutionized how people spread and consume information; these changes will redefine who we are as consumers, merchants, and individuals. With the expansion of computers and the Internet connectivity, people are able to share more of their lives with family and friends. Technology has offered the world so many different services, which include emailing, instant messaging, search engines, blogs, and Wikipedia. These services have changed the way we communicate with others, our knowledge, and the way we conduct business. With the increasing usage of the Internet, developers continue to find ways to improve technology and the way we utilize the Internet. Technology has a wide range of different aspects and concepts, which includes protocols. There has to be rules, and objectives in any and everything we do, and protocols governs communications, errors, detections, messages, and speed. There are three technology concepts behind the Internet, and they are packet switching, Transmission Control Protocol/Internet Protocol (TCP/IP) communications

Local area networks (LANs). DEFINITION The concept of local area networks (LANs) is not new. It represents a logical development of computer technology. With the advent of microcomputers in the 1980s many office workers began bringing their own disks into work, compromising data integrity.

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.
