The Network

Networking: To summarize the wired configuration, this network starts with the public internet that connects to a WAN (Wide Area Network); a good example of a WAN network is an ISP (Internet Service Provider) (Ocens, 2012). This WAN connection is T1 that connects to the T1 Demarcation Router in the computer room; this terminates the T1 line and provides an Ethernet Connection to the Main Router as well as a T1 connection to the WAN. The main router creates LAN connectivity and connects to the PIX Firewall and the Ethernet Switch; the firewall controls access to the public internet through the main router’s connection to the WAN. The LAN connection creates a high-speed connection for the computers, servers, routers, and printers needed in the organization. The servers, the data server and the mail server, connect directly to the ethernet switch to give access to all the devices on the network. The ethernet switch connects to the cross-patch panel, this panel connects all the RJ-45 (Registered Jack 45) outlets in each office. The horizontal cable runs out of the computer room from the cross-patch panel, above the ceiling, down the wall, and connects to a faceplate for RJ-45 ethernet. An ethernet drop cable, otherwise known as a UTP cable, is conneted from the faceplate to the computer’s ethernet card. Since the shipping office in the warehouse is a further distance, fibre optic cable runs from the computer room to a remote ethernet switch in the shipping office. Past the…

NETWORK CABLES Network cables are the medium used for information to move from one network device to another. There are many different types of cable which are often used in Local Area Networks. Most network set-ups are likely to use a variety of network cable types. Whereas in some other cases, a very basic network may only utilise one kind of network cable. The cable needed varies according to the client’s needs for example the size of the network (PAN, LAN, MAN, WAN), the network…

Maximizing shareholder’s wealth is the most important business managers or chief executives ' responsibility. When the company becomes public, investors supply assets and cash. In order to keep up those assets, the chief executive or manager has to make decisions to increase the shareholder 's return, which occasionally can be inhuman and unethical. In Network, it displays Frank Hackett’s willingness (Robert Duvall) to make decisions, which is in his favor but intentionally puts Howard Beale…

I. Physical Network Design A. Network Topology Business Needs Topology is important as it is the way the computers in this business will be lined up and how they pass information from one to the next. A wrong topology can cause a lot of extra expensive and headaches for the IT personal. The correct topology will make it easier to manage and will help keep the system running smoothly. A physical topology must be picked that can be easy to set up and easy to maintain. It should allow systems to…

social structure of policy implementation, we drew on data from a large study of social networks among professional development providers in the San Francisco Bay Area in the wake of the adoption of the Common Core state standards in math standards (CCSS-M) and Next Generation Science Standards (NGSS). The San Francisco Bay Area was chosen for two reasons. First, California had adopted and begun implementation of the CCSS-M and the NGSS. Second, prior research has suggested the importance of…

Place these servers along with the other related servers (e.g., VPN server) in a DMZ area. Note: The DMZ is connected to the Internet through a firewall.
DMZ (demilitarized zone) is a physical or a logical sub-network that contains and will expose UpHillCars Inc.′s external facing services to the internet. (Anon, 2014) This will add additional security to the organizations LAN. An external attacker only has direct access to equipment in the DMZ rather than any other part of the network. The…

This diagram illustrates a Local Area Network implemented using an Ethernet connection on a bus topology model. It is a LAN because there is no indication of considerable distance between the computers or departments. It is in Bus topology as since the computers connect to the network by connecting to the network cable. This as opposed to a star network topology setup. Next to each network component is an Internet Protocol (IP) address. Each IP consists of four number whose value can range from…

A network allows computers to exchange data. In computer networks, devices exchange data using a data link. The connections are made using cable or wireless connection. Maintaining network security throughout an organization can be quite challenging and is indeed a tough job, but it is attainable and can be achieved. Network security is all about keeping the network safe for all devices and computers on the system. There are certain measures and skills needed to keep a network safe. There are…
