AT&T Corporation

AT&T AT&T is one of the most popular companies that provide variety of services; voice, data, and communications and is the largest provider for mobile telephony and fixed telephony. There is a main server called the proxy server which AT&T uses, which acts as a server and a client in making request on behalf of other clients, it can provide routing and can enforce policy. The proxy server is an application layer service that routes SIP request and replies; it hides the identities of endpoint and it may be redundant because its functions overlap with those of the firewall proxy service. Proxy servers are rarely implemented in SIP networks because of the cost, delay, delay variation, and complexity they add to the service. The next server would be a redirect server; which makes mobile and nomadic users reachable as well as users who have new phone numbers it is a part of the availability service as well as geographic location services provided by the location server. The type of switches this company uses is the Cisco switches they are used to create a network by connecting and controlling all of your organizations computers, printers, and servers and it can also increase efficiency, productivity, and allow your devices to talk to one another through information sharing and resource allocation.
Cisco offers two types of network switches: * Cisco unmanaged switches, which are found in home networks work right out of the box and are not designed to be configured but, they have less capacity than managed switches. * Cisco managed switches are great for small business uses and they are configurable which allows them to offer much greater flexibility and networking capacity. * Cisco managed switches can be monitored and adjusted either on-site or remotely. * All Cisco switches offer high-performance, reliability, and security no…...

...A PART OF ME Hello, my project is about classic cars, and trucks restoration. This project may seem to some as a simple project to report on. If you have had the opportunity to be a part of a restoration project directly or indirectly, you may understand the passion that comes with a project like so, if you do not have the passion before the project it is likely you will develop it sometime during. I want to take this time and explain to you how easy it was for me to figure out early in life how much I love muscle cars. I really like some of the newer aero dynamic looking vehicles, but combining the new look and the old muscle car look really brought back a feeling of a personal touch “a part of me” to something special to be admired by many. There use to be a time when men and boys did things together that women and girls would not do. And there use to be a time when women and girls did things together that men and boys would not do. I remember a simple little game me and some of my friends use to play, it was called counting cars. Every time a car came by that I was passionate about I would say hot diggady dogg that’s my car. As time went by daily we would get a friendly honk from various drivers and an occasional burn out, to me and my friends this was well worth the all day waiting and waving.

Patton-Fuller Community Hospital Networking Project

...Week Three Individual Paper Patton- Fuller Community Hospital Networking Project CMGT 554/IT Infrastruct In week’s three individual dissection of Patton-Fuller Community Hospital Networking Department, I will discuss three topics that will help with a better understanding of the Hospital’s Networking Department. During the first topic, a complete analysis will be completed on the network systems in use. While covering the second topic, discussion on what standards may be missing from the Hospital’s current network. During last topic, I will identify the Hospital’s wireless technology in currently in use and how it may enhance the hospitals network. Patton-Fuller Community Hospital currently uses a Local Area Network (LAN) standard within the hospital with certain Departments using a Wireless Local Area Network (WLAN) standard. The Hospital’s top view IT network perspective has the Hospital divided into two sections, the Clinical Areas and the Administrative Function Areas.   The entire Hospital‘s backbone (BN) network structure is a 1000 BaseT Ethernet cable. A 1000 BaseT Ethernet cable also known as IEEE 802.3ab, is the standard for gigabit Ethernet using copper wiring (Wikipedia, 2010). However, in the second half of the Hospital’s network structure, the Clinical Areas, a 1000 BaseF Ethernet cable is the standard.

...Final Project An OSI is a model made up for seven different layers starting from the top down, basically what an OSI does is it breaks down its seven layers and different components to make it easier to work with, it controls how network systems communicate to each other. This model is used to help determine what the problem is in a networking community. For example, each layer represents its own function. The physical layer is all of the physical things that connect with each other, like the wires. Layer 7 (The Application Layer): This layer is what the user interacts with, like Google Chrome, Safari, and Firefox. This application is how things look. Layer 6 (The Presentation Layer): This is the layer that the operating system works on. Layer 5 (The Session Layer): This layer deals with the communication that creates a session between the two computers. You’re computer has to create a session with the web server in order for it to work. Layer 4 (The Transport Layer): This layer decides the amount of information that is sent out at one time. If you are on a website it controls how much information you communicate to the website, and now much is communicated back. It goes back and forth to make sure there isn’t a over abundance of communication going on. Layer 3 (The Network Layer): This layer routers operator layout. This is the level that routers operate at. Every router uses this layer; this layer is where you can find you’re ip address. Layer 2 (The Data Link......

Lan/Wan Networking Project

...I have recently started working as a Networking Consultant for MTI Technologies Inc. I am also the person assigned to help your group improve your network. As I was informed, and feel free to correct me, that to improve this network you decided to switch from 10BaseT to 100BaseT, I hope that you know that with this improvement might get a faster service but as a consequence the number of equipment that can be added would be less. But after this change, your network not still satisfying you. My first guess to your problem would be NIC cards, your network might have an NIC card that is not compatible or capable of 100BaseT and this issue won’t let the others run more that 10BaseT. To begin with, I would suggest that you to purchase a new NIC card (Network Interface Card) and also remind you to make sure your drivers are updated whenever an upgrade is done. (This is very important). Before buying a new NIC card for your motherboard you must always update drivers when upgrading anything on a computer the computer never knows automatically unless the software was built that way. The solution can be as easy as going to the website of the original make of your NIC that is attached to the motherboard of the PCI slots and upgrade the drivers for these Thank you very much for the attention; feel free to contact me if any questions or information is needed. I will be on top of your issue until your problem is solved. Clevy Aponte Networking Consultant at MTI Technologies......

...Networking in My Life and Career Angel Salvador Maldonado DeVry University Author Note This paper was prepared for CEIS-100 taught by Professor Reinaldo Fernandez. Course Project Week #: 2 Networking in My Life and Career A network is defined as a group of computers that are connected to share information. An NIC is a Network Interface Card. It is the physical component of a computer that allows a computer to connect to a network. Three types of media used for network connections are cable television coaxial, fiber optic cable and wireless connections. There have often been times when I have had to access my home wireless internet network and have not been able too. I start to troubleshoot by disconnecting and re connecting to the wireless network in the Open Network and Sharing Center. If that does not work, I check my wireless router to see if the lights on the router are green indicating that it is working properly. If there is a red or orange light on the router, I unplug the power source of the router and let it reset. This usually resolves the issue. My career goal is to become a Network System Administrator. That being said, I will be dealing with networks on a daily basis. A Network System Administrator is responsible for designing, installing, maintaining and upgrading networks in businesses of different sizes. I still have not taken any networking classes. I do know that by the time I obtain my Associates in Network Systems Administration I will have......
