...upgrading. • Future exspansion- can the existing coaxial infratructure support the companies growth over the next 20 yrs. • Cost- how much will, it cost the company for initial upgrade and future growth. These are our recommendations: Your company currently has 20 workstations connected with coaxial cabling. The company wants to expand and double its size in the next 20 years. We recommend that you upgrade your cabling at the minimum to a twisted pair CAT5 or CAT6, preferably CAT6. Coaxial cable for network connections is obsolete and does not provide the performance or scalability to support a growing company. All though twisted pair cabling is a suitable choice for your company, we would also like for you to consider the possibility of using Fiber Optic cabling. Fiber Optic cabling would be our preferred choice for your company. The benefits of twisted pair cabling are that they reduce cross talk on multi pair cables. Twisted pair cables transfer balanced differential signals more efficiently than coaxial cable. Twisted pair cabling is easy to install, improves...

...The Benefits of Twisted Pair Cable Introduction to Networking October 29, 2013 Ocper Inc. is a small company that has no one dedicated to information technology or networking on the staff, and there are 20 Windows peer-to-peer client computers all connected via coax cabling. The president has indicated that the company plans to double in size over the next two years, but she is weary of drastically changing the computing environment. This is my first assignment, but I feel that I have a very good plan to help give them a faster, more secure, and efficient network. The first change that I would recommend would be to move away from a peer-to-peer network to a client/server network. I would explain that there are many advantages to switching to a client/server network such as (Dean, 2009): * User logon accounts and passwords for anyone on a server-based network can be assigned in one place. * Access to multiple shared resources (such as data files or printers) can be centrally granted to a single user or groups of users. * Problems on the network can be monitored, diagnosed, and often fixed from one location. * Servers are optimized to handle heavy processing loads and dedicated to handling requests from clients, enabling faster response time. * Because of their efficient processing and larger disk storage, servers can connect more than a handful of computers on a network. The advantages of a client/server far outweigh any possible disadvantages. ...

...The Benefits of Twisted Pair Cable July 28, 2012 The Benefits of Twisted Pair Cable The current network model that is being used by your company today is the peer to peer model. This model is an ideal selection for a company or organization when there are very few computers. Since your organization currently has 20 Windows peer to peer client computers I would like for you to consider moving towards the client server network modelOnce a peer-to-peer network grows beyond 10 computers, it will likely begin to suffer from performance and from administrative problems (Posey, 2000) In the client server network model network hosts have specific roles which are assigned to them. There are certain host that are assigned as servers, which will provide network resources to the workstations. Unlike the current peer to peer model that is supported in your organization today in which everyone workstation has the same or similar operating systems. There are several benefits for your organization to consider to transitioning to client server network model. One of the major benefits of the client server network model is scalability. Since we know the potential for this organization to double in size over the next two years scalability is a key factor. It’s very easy to expand the size of your network with client server model because it will be easy to just add on workstation. Everything is centralized to the server. This server will be the centralized...

...THE BENEFITS OF TWISTED PAIR CABLE Recommended Changes and Benefits As I am a consultant for NCF, the Networking Consultant Firm and my first assignment are at Ocper, Inc. We will first study to their current networking and current technology that they are using. First, they have use coax cable to connect 20 windows peer to peer computers. The president had told me that he expect his company to be expand and double in size, in the next two years. What NCF will recommend is to take a closer look at benefit of twisted pair cable. Since the business now needs to connect 20 computers, I would explain how twisted pair cable will help them. Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. They need to be more understand their current situation so; it could help them to get the highest performance from it. The twisted pair cable come with in two varieties; shielded and unshielded twisted pair. For this case, I would choose the unshielded twisted pair to be the solution because this cable is the least expensive cable, there are pro and cons, it may be susceptible to radio and electrical frequency interference (it should not be too close to electric motors, fluorescent...

...Benefits of Twisted Pair Cable Gregory M. Dowell CIS 175 Professor Blanson November 3, 2013 Benefits of Twisted Pair Cable Ocper, Inc. is a company that currently has twenty employees connected in a peer-to-peer network. Over the next two years they are looking to double in size and are looking for a solution to their computer networking needs but are weary of any drastic changes. Currently all of their computers are connected using coaxial cable. Through this paper I will show the benefits of changing their network configuration, as well as replacing the coaxial cable with twisted pair or possibly fiber optic cable. My fist suggestion is to reconfigure their network from peer-to-peer to a client/server network in a star configuration. By doing so, there will be a central computer used as a server that would facilitate communications and resource sharing between the other computers on the network. With this server clients will be able to share data, data storage space, and devices such as printers. The users will still be able run applications and save data to their own computer, but will also have the option to save it to the server (Dean, 2009). Saving the data to the server will enable better security of the data since backups to the system can be scheduled every night. In addition, each client can be authorized only the access to the applications they need. In the peer-to-peer configuration each computer can communicate with each other and...

Upon arrival at Ocper, I learn from the president that there is no one dedicated to information technology or networking on the staff and there are 20 Windows peer-to-peer client computers connected via coax cable. The president also addresses her concerns for growth. She feels that the company will double in size over the next two years, but does not want a drastic overhaul. For this assignment I will hit 4 main topics. First I will describe what changes I would suggest for the current network type and explain why I am doing it. Second, I will describe why I would recommend upgrading to twisted pair cable from coax cable for all current and new client computers on the network. Third, I will discuss the possibility of implementing fiber optic cable in to the network. Finally, I will display research costs and analysis to facilitate an upgrade on the network. As above mentioned, the current network is 20 Windows peer-to-peer client computers utilizing the bus topology. Also important to note is the fact this company lacks an employee with an IT background, therefore they have been inclined to set up a simple peer-to-peer network due to its...

...can be minimized in the event of the main hub/switch failure. The initial cost of equipment can also be a concern. The cost of the hub/switch will run about $750 to $1800 for each hub/switch, if you add a backup that price will be $1500 to $3600. Depending on the work station NIC cards you may need to upgrade to new cards that accept the Cat 5e cable. I would recommend installing Cat 5e or Cat 6 (speeds up to 1000 Mbps, 1 gigabit per second Gbps) twisted pair cables rather than using the coaxial cable. The twisted-pair cable is designed for telephone communications and modern Ethernet networks. The pairs of wires are twisted to give protection against crosstalk; crosstalk is interference of noise generated by adjacent pairs. Just like any electrical wire a magnetic field is produced when current flows through it. By twisting the wires together in pairs the magnetic fields will be opposite of each other and while null or cancel out. Two basic types of twisted-pair cable exist: unshielded twisted pair (UTP) and shielded twisted pair...

...I am writing this report as requested by you for me to assess the network being used in your company (Networking Consulting Firm). I will be listing my recommendations for you to consider and perhaps implement to make your company more efficient. First off, I would strongly suggest that your company switch to a client server/network from the peer-to-peer network that you currently have in place. A peer-to-peer network was good enough before during the early stages of your company, although by using this kind of network, important data can be snatched pretty easily by someone that intends to sabotage your company. This can be easily stopped by implementing a client/server network. A client/server network will safeguard all your data from unwanted eyes. The network administrator can also set security measures such as giving certain people access to certain files. I would also like to suggest changing the wiring structure of your network. I see that you are currently using coaxial cable in your network. Though coaxial cables have their advantages the disadvantages are pretty hefty. Listed below are some disadvantages that could cause your business some trouble. * Problems with the deployment architecture—The bus topology in which coax is deployed is susceptible to congestion, noise, and security risks. * Bidirectional upgrade required—In countries that have a history of cable TV, the cable systems were designed for broadcasting, not for interactive communications. Before...

...With a client/server network you will experience quite a few advantages over your current peer-to-peer network which include having user logon account and passwords in one centralized location, access to multiple shared resources, problems on the network can be monitored, diagnosed, and fixed from one location and faster response time because servers are optimized to handle heavy processing loads (Dean, Network+ Guide to Networking, 2009). I would suggest that we upgrade from the current coax cable, which has a data speed ranging from 10 MB per second up to 350 MB per second, to a twisted pair cable that has a data speed of up to 1 GB per second (Gates, 2011). Twisted pair cable consists of a pair of insulated wires that are twisted together. The twisting of the cables helps to reduce noise pickup from outside sources. Since you plan to expand your company over the next two years, using the twisted pair cable will make it much easier to add the additional workspaces. If we set up the network to accommodate the extra workstations you anticipate, when the time comes you will just need to plug the cables into the designated switches and be...

...ahead with the original set-up that I had suggested. That would be a client/server-based network. The advantage of a client/client/server-based network is that the data files that will be used by all of the users are stored on the one server. Which gives you a central point to setup permissions on the data files, and it will give a central point from which to back up all the data in case data loss should occur. I would recommend they switch to a twisted pair wiring because there are several advantages for the use of twisted pair cabling. It is very flexible to make it very easy to work with. It is also less expensive than coax cable. The reason why twisted pair cable has become so popular is because networking protocols and standards were designed to support twisted pair wiring. There are a few disadvantages such as the casing; the sheath around the twisted pair networking cabling that is relatively thin. It doesn’t have a second insulator like coax and it is a bit more susceptible to electromagnetic interference, and twisted pair is a bit more susceptible to eavesdropping. A virtual private network (VPN) is a private network that interconnects remote (and often geographically separate) networks through primarily public communication infrastructures such as the Internet. VPNs provide security through tunneling protocols and security procedures such as encryption. For example, a VPN could be used to securely connect the branch offices of an organization to a head office network...

...1. What is crosstalk? How is it minimized in case to twisted pair of wire? Crosstalk occurs when there is electromagnetic interference between two signals and one transmission can intermittently bleed into another transmission. People used to have this happen during telephone calls when you would hear a second calls conversation coming over your line. Twisted pairs of wires help reduce this interference as each line of the pair carries an opposing signal of equal strength causing any electromagnetic interference generated by either to canceled out by their paired wire (Christianson, 2014). 2. Why two separate frequencies are used for uplink and downlink transmission in case of satellite communication? Two separate frequencies are used so...

...wiring in buildings is the most important market for the copper industry. Roughly half of all copper mined is used to manufacture electrical wire and cable conductors. Copper used in building wire has a conductivity rating of 100% IACS (International Annealed Copper Standard) or better. Copper building wire requires less insulation and can be installed in smaller conduits than when lower conductivity conductors are used. Copper is also used to make communications wire (Telephone, Cable TV, and Ethernet) such as coaxial wire and Twisted Pair cables. Twisted pair cabling is the most popular network cable and is often used in data networks for short and medium length connections up to 100 meters (328 feet). It’s popular due to its lower cost as compared to coaxial cable or Optical Fiber. There are four (4) types of Twisted Pair cables: UTP (Unshielded Twisted Pair); STP (Shielded Twisted Pair); ScTP (Screened Twisted Pair) and S/STP (Screened Shielded Twisted...
