Voice over Internet Protocol

Multi-tasking in the Internet age Introduction Multi-tasking could be referred to as the capability of doing more than a single work, simultaneously. Human multi-tasking is a term which has originated from the computer multi-tasking itself, where a computer performs more than a single task at a time. Human multi-tasking example could be as simple as sending an email while talking over a phone call. One would think that he’s actually saving the time, but I reality he’s killing extra time, as he…

light (Mercer, 2017) It functions by using common Light Emitting Diodes (LED) to facilitate data transfer at speeds up to 224 gigabits per second (Mercer, 2017). Li-Fi proposes a world where common sources of light are able to connect us to the internet. The term Li-Fi was invented by Harold Haas, a University of Edinburgh Professor in 2011. He foresees light bulbs acting as wireless routers and later went on to set up a company, pureLiFi with the goal of becoming an authority in VLC (Mercer,…

Internet and Loyalty, Resistance and Deviance Through internet, anyone can broadcast their voice both as identified or anonymous. In comparison to before internet; you had to go through controlled channels such as radio or television, physically be present in protests, or write letters or make phone calls which have a limited reception. So how does internet affect loyalty, resistance and defiance, and especially voice and exit? Inflation of Voice Via internet, anyone can access a multitude of…

ASICs encourages effectual measure of data packets through the system. Packets run over the Packet Forwarding Engine in sequence. First packets reach at a receiving PIC interface. Then the PIC permits the packets to flow to the input and output administrator on the FPC. The input and output administrator checks the packet headers, splits the packets into 64 byte data cells and permits to flow through the cells over the mid plane to the SSB. A Dispersed buffer administrator on the SSB dispenses…

people don’t know what the internet really is. In his book Tubes: a journey to the center on the internet, Andrew Blum goes all around the world to finally put an answer to the question. Blum acknowledges how we are becoming a more internet dependent society, and questions why the world inside the screen seemed to have no physical reality. Blum battles the public’s conception of the internet as a “nebulous electronic solar system, a cosmic cloud” (Blum 6). The internet is not some ethereal…

This protocol is classified into rounds; every round composed of two phases; Set-up Phase (1) Advertisement Phase (2) Cluster Set-up Phase Steady Phase (1) Schedule Creation (2) Data Transmission A. Setup Phase: Every node selects independent of other nodes if it will become a CH or not. This selection takes into consideration when the node behaved as a CH for the last time. In the advertisement phase, the CHs inform their neighboring node with an advertisement packet that they become CHs.…

In this section the fast-recovery algorithm that makes TCP NewReno[1] perform better than the Reno[3], is described. During congestion avoidance if the sender receives triple duplicate ACKs, then it performs fast-retransmission and enters into fast-recovery. In fast-retransmit the sender retransmits the lost segment,sets the threshold value for slow-start as ssthresh = cwnd/2, and sets congestion window, cwnd = ssthresh+3 segments. In fast-recovery, the sender increases its congestion window by…

the parts that make up a computer. Components include software and hardware. Proxy server: A proxy server is basically an server that bridges the gap between you and the internet. When you have proxy up and running the other computers from the internet cannot see your IP address so it covers you in something known as an internet camouflage. The computers can only see the proxy's IP. Another use of proxy servers is to access sites that are not usually available to you. For example if a site was…

variety of network cable types. Whereas in some other cases, a very basic network may only utilise one kind of network cable. The cable needed varies according to the client’s needs for example the size of the network (PAN, LAN, MAN, WAN), the network protocols and even the network topology. Different cables have different characteristics and it is important to learn about the different cables available on a network to develop a successful network. In this report I will be discussing and…

Ethernet II Frame Part 2: Use Wireshark to Capture and Analyze Ethernet Frames Part 1: Examine the Header Fields in an Ethernet II Frame What is significant about the contents of the destination address field? It starts with the broadcast ARP protocol from the router asking who has 192.168.2.22. Then it starts showing the source ip address then destination addresses then rebroadcasting from your router. ____________________________________________________________________________________ ____…
