Advantages And Disadvantages Of Wifi

Question 1 Wireless Option
Wireless transmission media uses the air as its medium. Wireless technologies use Radio Waves, Microwaves, Satellite Communication or Infrared. The most common one that is used is Radio Waves.
Advantages
One advantage of wireless communication would be that it can be much cheaper to implement as wireless networks do not require the higher cost of cables and maintenance cost since wireless networks use less equipment. Another advantage to the wireless signal would be its adaptability. Wireless signals can easily be set up in different locations but also easily moved to another location when needed.
Disadvantages
Wireless networks have limited bandwidth. One main disadvantage of a wireless network is concerning …show more content…

These labs will have different devices such as computers and printers. We are not giving the number of computers of printers required so for this university I will have ten computers and one printer in each of the three rooms. These rooms are within the same building so we can go for a cheaper wire as there will be less interference. Wifi is an option for this also but I don’t find WiFi reliable enough for a college. My choice of wire to use in this university is the twisted pair cable. This cable has two different types, unshielded twisted pair and shielded twisted pair. I will choose the unshielded twisted pair, this is the most commonly used twisted pair cable and is cheaper than the shielded twisted pair. When installing unshielded twisted pair we must be careful not to place the wire close to air-conditioning or fluorescent …show more content…

Again these laboratories will have ten computers in each. This is one of the most popular topologies in use today. Adding and removing nodes on a star topology can be done without any major concern that the entire network is going to crash. The cost of setting up this network is cheaper that the pervious mesh topology. All of the components on the network will be connected to the hub that is either a hub router or switch. Any data that is sent will first go through the hub in the centre.
The star topology is also robust so we would not have to worry when one connection between the computer and the hub fails. If this happened all other connections to the hub would not be harmed and will function correctly.
This topology also has some disadvantages. The main disadvantage is that if the hub fails then the entire network will fail and anything computer connected to that network will be disconnected. When selecting what central hub is needed we need to remember that adding new nodes will depend on the overall capacity of the central hub. This type of topology can be expensive to set up depending on the scale of the project.

    On the right, guess this transmission windows are usually filled from the receiver while the object has a good segment. Time scale below is usually within- Station A sends its very first facts part at t = 0. Station B possesses 6000 bytes to send, and who sends his first facts part from t = 2 ms. The most important feature associated with the problem is that acknowledgments are usually delayed more time by the very long segments sent from B to A. Answer2: a.

    Intermediate nodes, when overloaded, drop packets and hence the number of dropped packets is the largest compared to the other modes. Mode 1 gives the best performances is due to the fact that the sources distribute their flows on all available paths from the beginning hence reducing the probability of overloaded queues. However, it is observed that mode 3 tries to balance the load of a congested path on the other paths does not succeed in reducing the drop rate when compared to a simpler approach such as mode 2, at least for small network

    However, significant overheads in terms of communication and storage are incurred due to the flooding or multi-hop forwarding [10, 11]. 3) Without the network infrastructure, steady connection between nodes is difficult to be guaranteed, especially in large scale VANETs. In other words, the scalability is difficult

    To ensure the wireless signal is transmitted to every corner of the office space I recommend routers set-up with 4 directional antennas and a centralized Omni-directional antenna. The use of 2.4 GHz routers will increase data transmission speed 460-600 Mbps and provide 11 channels per router to support decrease in network collisions and prevent data packet from being dropped (Lazar, n.d.). All computing devices must be equipped with latest Windows 10 for business and use VPN tunnels to remotely connect and send print jobs to the Austin location. In addition, all workstations must manually be configured with the latest printer drivers to recognize the device.

    I am going to explain the current methods and protocols we use in a LAN environment to provide a high level of redundancy, such as EtherChannel, FHRP (First Hop Redundancy Protocols) and STP (Spanning Tree protocols). I will briefly explain how the protocols work & then discusses the latest implementations of the protocol and the environment you would expect to see them working in. The STP is a protocol that prevents loops from occurring in a switched LAN environments when a device has multiple interconnected paths. The protocols works by sending BDPU messages across in the interconnected devices, detects the loop then removes it from the topology by shutting down the port.

    Finally, the client sends a ACK packet back to the server, acknowledging the connection has been established. This sets up a full duplex connection between the client and server, meaning they can both send and receive data from each other simultaneously. After the 3-way handshake in the screenshot, an HTTP get request is made by the web browser for the website; the server ACKnowledges this and sends the website data to the web browser. For ending the connection, a 4-way handshake is used. In the screenshot, the client first ACKnowledges that it has successfully received the HTTP data, and then the sever sends out a FIN packet, which the client ACKnowledges, and then the client sends out a FIN packet, which the sever then ACKnowleges, and then the connection times out, thus ending the data exchange

    Devices like a hub or a switch; has much less capabilities as they are only capable of performing basic network functions. For example, a hub is usually used to transfer data between computers and network devices, but however, it doesn’t analyse or do anything with the data it contains. In the other hand, routers can analyse the data being sent and transferred over a random network, then change how it is packaged and once it has done that it can send it to another network. There are two different types of a routers out there, they are: the router and the wireless router. In the example picture above, the router allows all the computers and other network devices to access the internet.
