Nt1310 Unit 1 Network Analysis Paper

1)A network is when two or more computers are connected together and are able to share data and communication.

During this section of my blog you would be able to view all the different types of typical services provided by networks and the purpose of each where I discuss the advantages and disadvantages of them all.

Crossover cable - A crossover cable is a type of twisted pair copper wire cable for LANs (local area network) in which the wires on the cable are crossed over so that the receive signal pins on the RJ-45 connector on one end are connected to the transmit signal pins on the RJ-45 connector on the other end.

Computer Network: A LAN (local area network) that connects computers in a house, at school or at work.

This created physical connection between PC’s and the network line. Connected data’s are transporting data’s through the network. Cable is a medium through which information usually moves to one network to another network.

There are 3 security features about Hamachi: (1) Encrypted communications：Secure communications using AES 256-bit encryption, over public and private networks; (2) Centralized access controls: Control network access and usage, including password management, network authentication, network locking, and ongoing network membership; (3) Network / client configuration management：Configure default settings for individual networks and clients, with support for full, restricted and minimal client interface modes

Each layer has a specific function and the layers work together to allow an application to send data over a computer network without really specifying the exact protocols and/or physical wiring within each layer. In line with the figure above, when the first CEO sends an email message to the second CEO, email ‘application worker’ firstly prompts the first CEO to enter a message and specify that the receiver is the second CEO. The application worker then creates the necessary data package with message contents and the destination email address and send s this to a ‘transport worker’. The transport worker provides transport integrity. The transport worker may establish a connection with the receiver (second CEO); monitor the overall

1. Identify the types of connectivity devices being used the local are network at your school or workplace, and describe why they are being used. Are any of the devices networked managed? How do your network administrators use the information collected from the managed devices?

Bus – All computers and devices are connected asynchronous to one linear cable known as a trunk or generally known as a backbone. each ends of the trunk should be terminated to prevent the signal from bouncing duplicate the cable. as a result of the network

Some of the networking basics are discussed below like TCP, UDP, TCP/IP, and OSI model.

How would you define a network? What is bandwidth? What is a NIC? List three types of media used for network connections.

Network Devices: Network devices include all devices, which help make a network workable. These include Hubs (Enables more than one computer to interconnect on a network), Routers (Connects two networks), Switch (Joins multiple computers within one LAN and a Bridge (Allows one network to connect to another

A LAN is a network of computers in a specific area interconnect using a variety of network media. For example, WBHS LAN are all the computers connected to the WBHS network via Ethernet, Wi-fi or other. This is different from a WAN (Wide area network) which extends to a much wider area such as a town, city and country. LAN are usually more restricted in access and more numerous.

Coaxial cable are classified according to it impedance. The one used in this exercise will use the impedance of 70 ohms with RG-58. This can be used for the discussed high speed internet requirements discussed above.

A computer network is a network that consist of two or more computers that are able to share information between them or their users. There are a large variety of different networks and the advantages or disadvantages are strongly related to the type of network we choose.
