Voice over Internet Protocol

Baldeo Persaud NT1210 Unit 9 Assignment 1 Key Terms: The Internet- The global network formed by interconnecting most of the networks on the planet, with each home and company network connecting to an Internet service provider (ISP), which in turn connects to other ISPs. Internet edge- The part of the Internet between an ISP and the ISP customer, whether the customer is a company or organization with a large private TCP/IP network, or whether the customer is a single individual. point of presence-

A research project that synthesizes your knowledge of encryption, keys, and virtual private networks. Write a 5-7 page report on your findings. Encryption Encryption refers to a technique that facilitate the storage, transmission of information in a format that is unreadable to unintended audience. Unintended audience in this case may be hackers, sniffers, malwares e.t.c.the technique has been widely used to curb phishing in the current network security landscape. There are two fundamental techniques

online chat which offers real-time text transmission over the Internet. Most popular network IM system: AOL Instant Messenger (AIM), Yahoo! Messenger (YMSG),and Microsoft Messenger(MSN).are discussed. A. AOL Instant Messenger AIM defines different types of servers. Some of them are login, BOS icon, chat room setup, user search and chat room hosting. AIM uses client-server architecture for normal operations but uses a peer-to-peer approach for voice-chat sessions. B. Yahoo! Messenger (YMSG) YMSG

RLYT Task 2 Technological Solutions Banzal, S. (2007). Data and Computer Network Communication. Daryaganj, New Delhi, India: Laxmi Publications. T carriers, e.g., T1 and T3, are digital, leased twisted-pair lines, designed to carry voice (via Pulse Code Modulation (PCM)) and data communications up to distances of 48miles/80km. Approximate available bandwidth for a T1 is 1.5Mbps, and for a T3, 45Mbps of available bandwidth. T1s provide 24 64Kbps channels and a T3, made up of 28 T1s, can provide 672

(communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies. Early means of communicating over a distance included visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs. Other

7.1 Description: An Internet Protocol address (IP address) is a numerical label assigned to each participating in a computer network that uses the Internet Protocol for communication. What is an IP address “IP address” is a shorter way of saying “Internet Protocol address.” IP addresses are the numbers assigned to computer network interfaces. Although we use names to refer to the things we seek on the Internet, such as www.example.org, computers translate these names into numerical addresses so

Standards In this piece of work I will talk about different network types, topologies, architectures and specify the standards and protocols often related to them. Furthermore I will discuss network hardware and software required by a PC to join a network and access shared resources. Finally, I will look into different network services provided by the networks and the Internet. Network Types Personal are network PAN is a computer network which is there to communicate with other computerised networks.

or 256 Kbps for their voice traffic, whereas the Corporate Telecom office has allocated 4.5 Mbps of their 10 Mbps link to real-time traffic. 6.2 Site-to-site VPN and remote VPN& Internet Gen-i uses virtual private network (VPN) connections between their Gisborne office and Invercargill site as well as for the connection of remote users, such as at home or on the road, to connect to their network resources through Invercargill. VPN connections are established over the Internet, which Invercargill

individuals or devices. The second element of communication is the destination, or receiver, of the message. The destination receives the message and interprets it. A third element, called a channel, consists of the media that provides the pathway over which the message can travel from source to destination. Consider, for example,

IPv4 vs. IPv6 IPv4 and IPv6 are communication protocols (rules) which allow remote computers, servers, and other IT related devices to communicate. Both owe their existence to the massive growth of the internet. There was no need for IP-versions in 1969 when the internet began as ARPANET, a network set up by the United States Defense Advance Research Project. With only a few dozen computers on the net, each identified by a host name, they were able identify, contact and communicate with each other
