Ism 324 Assignment 2 Essay

RJ45 is a kind of connector frequently used for Ethernet set-ups. As Ethernet cables have an RJ45 connector on both ends, Ethernet cables are occasionally also named RJ45 cables. The "RJ" in RJ45 stands for the term "registered jack“. The "45" merely refers to the number of the interface standard. Each RJ45 connector has eight pins, which means that an RJ45 cable holds eight different wires. The end of an Ethernet cable has eight wires, in which each are a separate colour. Four of those wires are solid colors, while the rest of them are striped.

Explain the key components required for client workstations to connect to a network and access network resources.

The manager will need to ensure that they have the correct level of rapport with their employee. Too familiar in nature may be misconstrued as forward and harassing in the wrong context. However no personal rapport whatsoever may provide the receiver of the information with the impression that the sender of the information is just not interested. A fine line must be weighed up for each individual. When a good rapport has been achieved, then the person will uncritically accept suggestion or advice which they are given.

4. Use the Internet to research one to two applications of the identified wireless technology. List each application found. Reference the websites you used to locate this information.

Each synchronized period consists of one CCH interval followed by a SCH interval. The default division for each interval is 50 ms. Each CCH and SCH interval begins with a 4 ms guard interval, which is used by the radio to transfer control from one channel to another. Compared to other 802.11 standards, 802.11p has a number of distinguishing features. For example, in 802.11p, a transmitter broadcasts each packet to all other nodes in the network on the CCH. In order to prevent the network from flooding with Acknowledgement messages (ACKs), 802.11p receivers do not send an ACK to the transmitter. Thus, there is no feedback mechanism provided by the receiver, and consequently, Contention Window size of the 802.11p transmitter remains fixed. If a DSRC

Third, there is a set of software that allows the computer to send data across this network. There are a lot

An ad-hoc network is a collection of wireless mobile nodes that will dynamically form a temporary network without the use of any existing network infrastructure.

ANS: Direct sequence spread spectrum (DSSS) is a transmission technology used in local area wireless network transmissions. In this technology, a data signal at the sending station is combined with a high data rate bit sequence, which divides user data based on a spreading ratio.

3. What is an ad hoc network? In this network, the wireless clients (stations) communicate directly with each

1. Drawings showing a map of cable runs and placement of wiring rooms for networking devices

The IEEE 802.11 standard ensures that all stations, both radio-based network interface cards (NICs) and access points, implement access methods for sharing the air medium. When installing wireless LANs (WLAN), most people don't give much thought to these mechanisms. A detailed understanding of 802.11's medium access methods, however, will enable the user to deal more effectively with issues such as radio frequency interference, denial of services attacks and throughput

5. The ability of access points to change between 20 MHz and 40 MHz. This is good as the receivers for that access point changes. The access point can speed up or slow down based on the receivers in its broadcast area.

The company LAN is designed in what is known as a bus topology. Karl Falls describes a Bus topology as such: “A Bus topology refers to a single cable that connects all the workstations, servers, printers and other devices on the network. The cable runs from device to device by using tee connectors that plug into the network adapter cards. Each end device has a terminator on one end of the tee and a cable going out to the next device on the other end, while all devices in the middle have one cable coming in and one going out. The terminators on each end device simply stop the network signal from reflecting back into the cable and colliding with other transmissions.” The most

A primary system is made up of at least two computing devices either wired or wireless points of connection; these points are “network ports.” There are usually one network hub or network switch that permits their interconnection. The most standard “wired” computer networks are known as “Ethernet.” This is made-up of UTP (unshielded twisted pair) cables, and just about all personal computers have a UTP Ethernet Network port as standard. The printer also comes with an Ethernet port, making it easily shared amongst the user of a network. Other wired channels are coaxial cable used for cable T.V, Category 6 cables used for LANs, and fiber optic cables used for high-capacity trunk lines. Most local area networks (LAN) are used in small businesses network. Wired networks are much more secure than wireless networks. The Computer Age has shifted from a traditional industry to an economy is formed on information computerization. The arrival of the computer age is associated with the Digital Revolution. Today, the internet has generated attritions from billions of people and industries worldwide it is now a global cultural

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking
