Wide area network

Network hardware is the physical equipment that is required to allow devices to transmit data to another device. The devices have the ability to transfer over many types of media, but there are only two basic types of transmission. We first have the broadcast transmission which transfers the same messages to multiple recipients. Then there is point-to-point links that establishes a connection between two individual 's devices for data transmission. Networks rely on these two types of transmission for everyday networking. A personal area network is to "communicate between two or more devices. PAN networks can be used between devices owned by two different parties, or between two devices owned by one person" (Eric Cole). An example of this would be a keyboard paired to a computer. The most common form of a personal area network is Bluetooth Bluetooth is a technology that has greatly increased are mobility when using devices that are in a close vicinity of each other. They have become the common form for wireless communication between mice, keyboards, headsets, medical devices, and other handheld devices. "Bluetooth is a method for data communication that uses short-range radio links to replace cables between computers and their connected units" (Gunasekaran, 90). A Bluetooth network can usually only support a few…

Introduction This paper describes seven threats to a network belonging to a fictitious marketing company in Kansas City, Missouri. These threats are based on different IT infrastructure domains. The detail of these threats explains the possible outcomes and endeavors to point out “what is the worst that can happen” from that threat. Threats The first threat area is the user domain. The user domain consists of the actual users, or people, in the company, including subcontractors, vendors, and…

List the classification of network in detail according to the area covered. Also explain each classification of network in detail with its application. LAN – (Local Area Network) A LAN is a network that covers a relatively small area. It is a network that mostly links computers within a single building. Schools, colleges and office buildings would all use a LAN to interconnect their computer systems. They typically range from 1 – 10km. They are able to transmit data much faster than what can…

What is LAN? LAN stands for Local Area Network. LAN is a network that connects a group of computers within a building like a home, office or a school. For LANS to connect together and share information within computers, Ethernet is most commonly used. LAN does not need cables to connect to the different devices (e.g printers) however radio waves can be used to communicate. Difference between client-server and peer to peer network: Client Server Peer to Peer Resources can be removed at…

configuration, and supported standards. Specifically explain the VLAN concept and its use within the wired LAN infrastructure. What healthcare use can you envision for wired LAN? If unsure, search the literature for answers. A wired LAN connects computers within an organization in a network configuration and each PC on the LAN must connect to the network with a network interface card (NIC). The NIC needed varies by which cabling is used for the network (Cowley, 2012). NICs help to direct…

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…

Thesis statement: In The Red Badge of Courage, Crane uses lack of courage and courage itself in soldiers during the Civil War to show the pursuit of manhood through showing courage in the face of adversity. I. Introduction: I learned that courage was not the absence of fear, but the triumph over it. The brave man is not he who does not feel afraid, but he who conquers that fear. - Nelson Mandela II. Body Paragraph 1 A. Topic Sentence - The youth observes people running away and there lack of…

One week prior The man carefully stroked Reynia’s cheek while tugging her tightly to his body. The mans breath was acid smelling of whiskey. His eyes looked up and down Reynias small quivering frame. The man eyed her as though just a piece of meat, one so tantalizingly close. Reynia was the prey, and he the predator. The mans hot breath sent shivers down her neck. He licked his lips hungrily, as if preparing for a meal. Reynia jerked her head to the side and took a strangled gasp…

activation and deactivation of radio transceiver, data transmission and reception are the tasks that is done by the physical layer. There are different physical layers. The choice of physical layer depends on the applications. The different physical layers are: Narrow Band (NB), Human Body Communication (HBC) and Ultra Wide Band (UWB). NB physical layer is used for the activation or deactivation of the radio transceiver and data transmission and reception. The PSDU (Physical Layer Service Data…

Tremco, a commercial sealant and waterproofing company, was contacted on 7/27/17 for information regarding the issues observed. The sales representative, Liz Bailey, stated that the issues observed with the existing traffic system are consistent with urethane based traffic coatings. These traffic coatings are inexpensive to apply, but only have about a 5 year life expectancy. This can be further reduced in high traffic, high temperature, and high UV areas. Tremco recommended the use of a…
