It331: Technology Infrastructure Essay

Information is composed into a unit (called an edge) and sent over a system to a destination that confirms its effective entry likewise deals with the stream or pacing at which information is sent.

Synchronous is an adjective that describes an event that is coordinated in time. Synchronous communications works in a way that both hosts will be communicating consistently to continue that communication. By this I mean, that there should be continuous stream of data flow between both hosts to keep that communication going. An example of this is a phone call, when one host (person) communicates with another host, both hosts will have an active connection between them during Synchronous communication. The first host can send a packet of data (talk) while the second host will receive that data (Listen) simultaneously and then the first host will receive the data while the second host is sending the data simultaneously. This communication is used commonly used in telecommunications such as; phone calls, Skype calls etc. Synchronous communication is used in these cases instead of Asynchronous because these things require both hosts be active at the same time. Synchronous communication is also used for things such as streaming on Netflix which requires both the server and client accessing Netflix to be active. Peer to peer transfer (sending a file directly to a friend over the internet) also requires that both hosts be active, if only one host was active then the file wouldn’t be able to be

Routers and switches will be utilized to route network signals to all areas of this large network. Telephony systems will be introduced to serve the VOIP located at each location to assist with communication needs. Wireless technologies will also be needed to assist with mobility and other devices such as printers, laptops, fax machines, etc. Lastly, a physical firewall will be enforced at each location to protect the network from internal and external intruders.

It is operating on best effort delivery model, i.e. it does not guarantee delivery, nor does it assure proper sequencing or avoidance of duplicate delivery. These aspects, including data integrity, are addressed by an upper layer transport protocol, such as the Transmission

6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?

4. Exchange state – In this state DBD (Database Descriptor) packets are exchanged. DBDs contain LSAs (Link State Advertisement) headers. The Routers will use this information to see what LSAs need to be exchanged.

Data communication is the exchange of data between a sender and a receiver of the information. The components data communication has to have, to be a data communication are:

a) For the file to be sent continuously as one big message, we need to calculate transmission delay plus propagation delay.

All of the devises, i.e. routers, switches, computers, fax machines, credit card machine, printers and registers will all be connected with CAT 5 cables. CAT 5 is a measurement of quality and this cable allows for a 100 MB/ Sec data transfer. There are faster options that Kudler Find Foods could have chosen but for their application and budget, the CAT 5 cables will be more than enough to support their needs of the network.

Based on the following I would suggest that Cathy use wireless DSL. She has the choice of whether to use point-to-point or multipoint technology, and can determine which

This is a one dimensional form of communication. An interactional model provides not only the message sent, but also messagereceived and replied to by the receiver to the sender. A transactional model entails not only the sending and receiving of messages,but also the inclusion of non verbal communications.

infrastructure that will be used by hundreds of associates around the country. We see this as an

The Data link layer [also called layer 2] is responsible for moving a message from one computer or network device to the next computer or network device in the overall path from sender or receiver. It controls the way messages are sent on the physical media. Both the sender and receiver have to agree on the rules or protocols that govern how they will communicate with each other. A data link protocol determines who can transmit at what time, where a message begins and ends, and how a receiver recognizes and corrects a transmission error.

The first concept covered is the transactional nature of communications. Transactional nature of communications essentially

Advancements in the information technology sector have brought many benefits to the people all around the world.  Today with computer networking, we can chat, speak and see each other over a long distance. Data communication refers to the transmission of the digital signals over a communication channel between the transmitter and receiver computers. Communication is possible only with wired and wireless connectivity of the computers with each other.
