...Network Design Student Name Course 2 July 2014 Professor Identify hardware and software needed to secure your choice of networks against all electronic threats. A network that helps a workstation to connect with each other is called a Networking hardware. If a company uses both routers and firewall, the company is assured protection of both wireless and cabled networks that are used in the company. Network hardware is suitable in any organization in the keeping of the organizations network safe. In the software part I will choose to use McAfee Anti-virus security software. This software in conjunction with firewall is a sure way of protecting a company. Routers when used along with hardware are the best security hardware needed if the company needs to increase the security of their network to a level where none of the intruders can be able to access it (Radu, 2002). The function of the firewall in an organization is to ensure that all unwanted activities are blocked including hackers that can retrieve important and delicate information of the company. Hacking will be a very dangerous exercise where criminal can access the important information that a company has and use this information in blackmailing the company and its customers. Networking software’s also plays a major role in securing an organizations network security. The software has the capabilities of detecting viruses that may attack an organization and make an organization loose its critical...

...3.1.2 Types of Computer Networks Computer networks are classified based on the geographical length. A network can be as small as the distance between a mobile phone and its Bluetooth headphone. Also it can be as large as the internet itself. It covers the whole geographical world. Types of Networks • LAN • WAN • MAN (i) LAN (Local Area Network) A local area network is a self-contained network. It lengths a small area, such as a single building, floor, or a room. In LAN, all the nodes and segments are connected directly with short range wireless technology or cables. Each computer in a LAN has its own CPU. It executes the programs. It also access the data and devices anywhere on the LAN. Through LAN many users can share expensive devices, such as laser printers, as well as data. The LAN is used by the users to communicate with each other. They communicate through emails or by engaging in chat sessions....

...and a link to our environment that is almost magical. Telecommunications and computer networking have vastly increased our options on how and what we communicate, they have physically constrained us by leashing us with a physical wire to the network. But wireless communications brings us back to a form of communications that is inherently natural to us. There are three main types of networks that will be discussed on this paper, namely Local Area Network (LAN), Control Area Network (CAN), and Wide Area Network (WAN) (Rysavy, 2013). The purpose of this paper is to know what each of these networks are, how they work, and how each of them can be implemented. LAN Network: This is a data communications network connecting terminals, computers and printers within a building or other geographical limited areas. These devices could be connected through wired cables or wireless links. Ethernet, Token Ring and Wireless LAN using IEEE 802.11 are examples of standard LAN technologies. Local Area Network could be interconnected using Wide Area Network (WAN) or Metropolitan Area Network (MAN) technologies. The common WAN technologies include TCP/IP, ATM, and Frame Relay. LANs are traditionally used to connect a group of people who are in the same local area. However, the working group are becoming more geographically distributed in today's working environment, making virtual LAN. VLAN technologies are defined for people in different places to share the same networking resource (Edraw visualization...

This type of network is a private network that links computers at a single location, such as at a home or office building. A computer with the LAN connection is allowed to different network components like files, software and devices like printers and fax machines with in the private area. A computer can be connected to a router using Ethernet cable, or a router can communicate wirelessly using radio waves. The Internet is wider than the LAN, basically it is network of networks, and it connects the different networks (LANs and/or MANs) available worldwide and makes them public. The internet connection is called WAN (Wide Area Network) that connects millions of smaller networks with over a billion computers connected at any given time. The most basic difference between a LAN and the Internet then, is that a LAN is private and localized, while the Internet is public and worldwide. A LAN is connected to a router using Ethernet cable but the internet links millions of networks through T1 telephone lines, fiber optic cable and other technologies.

...Exercise 2.3.1 Briefly define LAN, MAN, PAN, and WAN. What is the critical distinction for these networks? What is the classification metric used here? LAN=Local Area Network-A local area network (LAN) is a computer network that interconnects computers within a limited area such as a home, school, computer laboratory, or office building, using network media. MAN=Metropolitan Area Network- A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). PAN=Personal Area Network- A computer network used for data transmission among devices such as computers, telephones and personal digital assistants. WAN=Wide Area Network- A network that covers a broad area (i.e., any telecommunications network that links across metropolitan, regional, national or international boundaries) using leased telecommunication lines. Exercise 2.3.2 Network Topology is the arrangement of the various elements (links, nodes, etc.) of a computer network. Essentially, it is the topological structure of a network, and may be depicted physically or logically. The metric used to define networks by topology is what clients they are using and how they are using them. A wide area network is larger than a metropolitan network for example.

...Computer Network A computer network is a group of computers that are interconnected by electronic circuits or wireless transmissions of various designs and technologies for the purpose of exchanging data or communicating information between them or their users. Networks may be classified according to a wide variety of characteristics. This article provides a general overview of types and categories and also presents the basic components of a network. Introduction A computer network allows sharing of resources and information among devices connected to the network. The Advanced Research Projects Agency (ARPA) funded the design of the Advanced Research Projects Agency Network (ARPANET) for the United States Department of Defense. It was the first operational computer network in the world.[1] Development of the network began in 1969, based on designs developed during the 1960s. For a history see ARPANET, the first network. Purpose Facilitating communications Using a network, people can communicate efficiently and easily via e-mail, instant messaging, chat rooms, telephony, video telephone calls, and videoconferencing. Sharing hardware In a networked environment, each computer on a network can access and use hardware on the network. Suppose several personal computers on a network each require the use of a laser printer. If the personal computers and a laser are connected to a network, the personal computers users each can access the laser printer on the network, as they need...

...2/19/15 Modern day lives depend on the network or more specifically the internet. One could find this to be true if one had no access to the internet for one day. Networks at a base level can be explained as two or more electronic devices connected electronically sharing resources to one another. How we classify each network depends on the devices that are connected and the size of the network. Not all networks are created equally. One could categorize a network based on the size geographically. Is it a network that is in a room or small office building? Or do the systems attached to the network span the entire length of a state? Local Area Network or LAN is two or more electronic devices that are connected with in a limited area such as a room or building. The evolution of LANs has changed as technology has become more powerful. Early local area networks used coaxial cable as a means to communicate. Then in the 80s twisted pair starting with Cat3 cable made the splash in networks. Modern local area networks use Cat5 or Cat6 cable. The main thing to remember about Local Area Networks is this is Local and does not span over a far distance. Unlike LAN’s the Wide Area network does span over far distances. A good example of this is a company that has one building on 4th street and 20 miles away they have another building on 175th street. The company’s computers can share resources between buildings. This is still a network but spanned over far distances. Most of the...

...choice of networks against all electronic threats. Networking hardware is hardware that is used to help work stations connect to a server. Although there are many different kinds of hardware like bridges, network cards the networking hardware that I have chosen to use in within my company’s network are routers, firewalls and switches. Using both routers and firewalls will help protect not only wireless networks but also those networks that use Ethernet cabling. I chose this hardware because I felt that it’s the best hardware to use when keeping my company’s network safe. The software that I have chosen to use is McAfee Anti-virus security software. This software along with the firewall will keep my company’s network safe and secure. Routers along with firewalls are the top network security hardware needed when it comes to keeping a network almost if not all totally secure. The firewall blocks out any unwanted activity as well block hackers from possibly hacking into our networks and stealing important information that pertains to our company and its customers. Along with the router and firewall networking software also plays a major part. The software is what the firewall uses to create its security barrier over the network. McAfee is one of the top manufacturers when it comes to network security. This software enables the use of not only the internet’s firewall but also the ability to detect viruses, anti-spyware upon the network, indicates safety of website upon network by color...

...University Network Telecommunication Professor Name October 21, 2013 LAN, MAN and WAN Computer networking is simply the communication between two or more computers that allow them to share information and hardware resources. This is really one of the most important contributions to the information age since personal computers were invented. The connection and communication of just two computers exchanging data and devices is the most fundamental of networking. The computer systems may communicate over a computer network and share their resources (Computer Network, 2009). A computer network can be wire and or wireless. When a network is wired, it uses cables to connect group of computers together to enable data communication. Wireless networks allow computers to communicate by using radio signals, so the computers aren't restricted by physical cables (Lowe, 2011). For example, it uses bluetooth, infrared rays and radio waves to send and receive signals over the network. Peer-to-peer (p2p) and client-server are the two computer networks in use today. In a p2p network, every computer has the same or equal capabilities and responsibilities. And with a client server it is nothing like peer-to-peer, some computers are the clients that request for resources and the servers make available the requested resources. There are many categories of computer networking, but the most common are local area network (LAN), metropolitan area network and wide area network (WAN). Local...
