Computer network Essays

Computer network topology is the way different parts of a network (like hubs, connections, peripherals, and so on) are arranged. System topologies characterize the format, virtual shape or structure of network, physically as well as logically. The path in which distinctive frameworks and hubs are associated and communicate with one another is dictated by topology of the network. Topology can be physical or logical. Physical Topology is the physical format of hubs, workstations and cables in the

establish a network connection to another company’s DNS. I also found out that each Physical address is uniquely made for each user. 1) Use the ipconfig/all command on your computer. What is the IP address, subnet mask, IP address of default gateway, and MAC of your computer? My IP address is 2601:140:8001:3239:3c47:3b50:b65f:88d2. My subnet mask is 255.255.255.0. My IP address of default gateway is fe80::1286:8cff:feec:de7a%15. My MAC address is BA-EE-65-33-85-BB. 2) Why does every computer on the internet

Walmart’s networking needs. The components of Wal-Mart system consist of the following: a) A bunch of computers in which to store the customer’s name, the number of items bought, the price of each item, including calculating the bill. b) Router/routers – They use 1 or 2 routers in order to give WIFI from the LAN network to actually gain means to entry to the seller and to the customer. c) A local area network system (Internet) which can be allocated through Wi-Fi to have means of entry to the internet.

1980s to 2000, the internet has been radically transformed from a research tool into a popular medium, influenced by fast-moving changes in technology, economy, and the politics of computing and communications. Its network proliferated from a national scale to a global [interconnected] network. Contrary to popular view, the internet was not developed in a straightforward[-linear] process as what many standard histories would suggest. They are rarely the outcome of a single vision of a group, but rather

the some basic process and essential commands I would use that would help me determine and address network problems. 1. My initial process is to check if the computer is connected to the network by checking if the Ethernet cable is connected to it? Is the router turn on? Is it receiving signal form the ISP? If the physical is working… 2. I would gather information of the local computer’s network by using “ipconfig” in the command line. Using this command will allow me to gather the IP, Subnet

online even your computer does not work still we can use another computer or smart mobile phone and can get our work effectively. C. Explain the purpose, relative function and transmission speed of the following Network cabling including: • Coaxial cable: Coaxial cable is used for the network communication, Video and audio which means this coaxial cable can be connected to the TV to get the signal from the satellites or music player system. There are 2 type of network cabling which

multiple locations. An intranet is a network of communication on the internet that is restricted to only those with specific access. For example, I work for Old Navy and we have an online system that is only available through the computers in the store and warehouses. It gives us the ability to scan in any item and see how many we have in our particular store and how many are available in the closest 8 locations; this information is pulled from our inventory network. From this system, I can locate an

Internet distinctively differs from other ordinary kinds of networks, specifically the London Underground system (reference to the network analysis of the 2005 London underground attacks). I will use technical terminology specific of the “network society”, and these will be explained in the next paragraph. Therefore, in this essay I will analyze and discuss my opinion of understanding the Internet as largely different from other kinds of networks, and I will support my point using some key scholar’s theories

purposes. Routers are the devices that join together the various different networks that together make up the Internet. In a network, routers are sophisticated switched hubs. They hold information about the addresses of computers attached to the network and can forward data efficiently to the correct location via an appropriate route. They are generally used as gateways where a local area network is connected to a larger network such as the internet. Web browsers are software programs that allow a person

separately and the original method is reconstructed by the receiving computer. The packets can travel using different paths, and if one packet is not received correctly, the entire message isn’t lost. This is part of what makes the internet so flexible and reliable. Circuits, on the other hand, are inflexible and unreliable. All it takes is one break for the system to fall to pieces. One very important part of the internet is the speed: computers must be in sync for them to

not all that are connected. 4.a network bridge connects two or more networks together and is similar to a switch because it sends the correct information to each connected pc .it can be hardware or software. 5. A wireless access point (WAP) allows devices with wireless capabilities to connect to a network without the need for any cables such as Ethernet. 7. DTE short for Data Terminal Equipment, a device that controls data traveling to or from a computer. 8. In network computing, DCE (Distributed Computing

3.6 STEP 6: Control Recommendations After compiling the different levels of risk for AT&T’s smart technology, it is easy to say there are many flaws in AT&T’s mobile network databases. Below are some key recommendations for AT&T to use in order to improve their security posture and mitigation of threats on their networks. Compatible Applications: As described before, AT&T’s smart technology is compatible with many different applications, like Google and Mozilla. These applications require some

Network internet layer This can be used to set the border line of what people can think of about the network. With this layer it will be able to interconnect with networks and will decide how the layers can do this process. It will be able to can concentrate and determine how the data will get from one remote network to the computer. Also it will take care with devices which are local. This is mainly tasked to take care of is routing which allows data to be moved the data across the series of networks

ip address that a user connects to via a web address. Domain names are used in various networking contexts, application-specific naming and addressing purposes. In general, a domain name represents an internet protocol resource such as a personal computer used to access the internet. An example of a domain name would be google.co.uk. Domain names are structured with two main elements, the information to the left of the point and the information on the right. The information on the right is called

Chapter 8: Working with Internet The advent of technological devices began with inventions like telegram, radio, television and computers. The invention of the internet brought about a revolution. Internet can be defined as, “a network of computers that are interconnected globally.” Internet is a networking infrastructure, which connects many countries worldwide. The medium of connection can be wired or wireless. The internet is intangible, which means it cannot be seen, touched and felt. We will

Kudler Fine Foods is a fast growing company with a network infrastructure that is quickly reaching its point of obsolescence. Kudler has currently outgrown their existing network framework, and their administration has distinguished a few areas of concern identified with their current system infrastructure, including information speeds, dependability of the system, and the absence of between organization electronic interchanges. Kudler Fine Food right now has three physical store locations, all

world. Wireless intercommunicating microprocessors are installed in devices and combined with computers to obtain an inter-communicating environment wherein information can be easily exchanged between the physical and computational world without user support. Wide-area cellular systems coupled with wireless LANs helped to achieve fully distributed and ubiquitous mobile computing and communication network across the

in the packet. In some cases, the switch itself also can determined the packets according to internal information. The switch technology can be applied to both local area network (LAN) and wide area network (WAN). LAN Switch can be used to transfer packets

In April 2009, the Federal Government announced its plans to finance the biggest Australian infrastructure investment rollout called the National Broadband Network (NBN). The NBN will be the biggest telecommunications reform in Australian history implementing fibre-optic and fixed wireless satellite infrastructure to replace the current existing broadband infrastructure with a more reliable broadband service. The NBN aims to provide a platform in Australian that not only harvests innovation but

ssue networks will not replace the more familiar politics of iron triangles (in Washington), but will overlay the once stable political reference points with the new forces that complicate calculations and decrease predictability. He believes that issue networks wield their power due to the fact that they comprise of a large number of participants with quite various degrees of mutual commitment or of dependence on others in their environment, the participants move in and out of these networks almost
