Nt1310 Unit 5 Satellite Communication

• “Data Link -Whenever two or more nodes share the same physical medium (for example, several computers plugged

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

Communication has been a real asset to humankind by having the capacity to exchange data starting with one then onto the next. While numerous diverse structures exist, for example, gesture-based communication, talking, and non-verbal communication, it is telecom that has changed the world all through the last hundred or more years. The information transfers framework has three separate things with a particular end goal to transmit what will exhibited. Person begin by the source or transmitter, which is then put into a medium or correspondence line, and ultimately there is a sink, or beneficiary that the data is yielded

Sir we already had a discussion on that mobile authentication paper ,explained the protocol and I said that instead of AES encryption and seed value.DNA can be used on the paper and quoted a paper for symmetric encryption so that it will be easy for her to generate the algorithm.

What technique used to by cable provider to enable data and voice on the same cable using different frequencies for video and data

A communications linkthat is outside the normal IP network, like a console cable or a phone call between two modems and aux port.

Copper twisted pair: Either 2 pairs or 4 pairs of copper wires are twisted and surrounded by insulation. Ethernet.

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

In data communication, they are always striving to increase throughput, this would include allowing nodes to transmit information over a single broadcast link without interfering with each other. To achieve this, multiple access protocols coordinate the transmission. There are three classes of multiple access protocols, random access, taking-turns and channel partitioning. With random access protocol, each node tries to randomly to access the complete broadcast link, without any regard to the other nodes. Taking-turns protocol utilizes some type of turning mechanism, which designates which node is allowed to transmit. Channel partitioning protocol divides the channel (time slots, frequency, code) and assigns them evenly between all of

Network coding allows multiple packets to be transmitted using a smaller number of packets thereby increasing throughput. Here a common single base station transmits data from a common single base station to intermediate stations where it is kept and sent out to the final destination or to any other intermediate stations at a later time. For a traditional network that employs multicast network, the stations receive a packet and forward it to the next node. Under network coding,

Switched virtual circuits also can provide "bandwidth-on-demand" meaning that when the line is at its peak carrying information more bandwidth can be made available. Also switched virtual circuits allow charges for connection to be made only for what the customer uses, unlike leased lines where you have to pay a flat rate (828-829).

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.

However, it was not until the 1960s that researchers started to investigate packet switching — a technology that would allow chunks of data to be sent to different computers without first passing through a centralized mainframe. A four-node network emerged on 5 December 1969; this network would become ARPANET, which by 1981 would consist of 213

Basic telecommunication characteristics are the medium that carries transmitted messages from point ‘A’ to point ‘B’. There is the simplex channel which is a communications channel that transmits data in one direction only, this particular channel is not advantages’ for business due to its one way nature. There is the half-duplex channel which can move that data to multiple locations, however it cannot move them all at the same time, in a company where speed is needed this may not be the best. Then there is the full-duplex channel which is similar to having two simplex channels, this one permits data to go both ways and multiple flows to move at the same time. A fourth option is broadband, which is communication channel bandwidth, and in general broadband simply means that it can move data and information at high speeds, in recent times the larger the business the more bandwidth is needed to keep

Modern wireless communications technology has almost become synonymous with digital satellite communications. It is hence, a key element in the current era of globalization as it has so largely been adopted as a primary means of communication. This paper attempts to investigate modern digital satellite communications providing a progressive transition from a conceptual to a more technical view of the digital communication process through a satellite from one earth terminal to another.
