Voice over Internet Protocol

Internet Protocol television (IPTV) is the process of transmitting and broadcasting television programs through the Internet using Internet Protocol (IP). A broadband connection is used as the medium of transmission for IPTV. Along consumers to tune in to their favorite programming when, where, and how they want. Improving the user experience compared to a traditional television transmission such as radio frequency broadcast, satellite broadcast and/or cable television. When downloading a file from

1. Introduction 1.1. What is steganography: Steganography is derived from the greek words stego which is known as cover and grafia which is known as writing which is combinedly known as “covered writing”. It is also defined as the art and science of communication in such a way that it hides the existence of the communication. In contrast to cryptography, steganography hides message inside other harmless message in such a way that the enemy connect detect that there is a hidden message inside the

TCP/IP Name Affiliation Date TCP/IP Introduction TCP stands for Transmission control protocol while IP stands for Internet protocol. They are merged together to form the Internet protocol suit which is a model for networking which consists of communication protocols which are used for internet and other similar networks. This protocol suite was designed and developed by the Department of Defense (DoD). It was developed in order to connect different networks which were designed by different

felt like watching them? IPTV(Internet Protocol Television) has the ability to do that and more by using internet protocols to transfer your TV programs to you “on demand”. We will discuss how IPTV works, some benefits it brings, and how it is changing the way we watch television today. There 's nothing new about it the use of your TV, it is still where the family meets to watch their favorite shows, gain information about the world, and just overall be entertained. Over the past decade, technological

using a Wide Area Network (WAN) network since its connectivity needs to span over a number of locations. The WAN connection should be able to provide the likeness of a Local Area Network (LAN) connection in regards to performance for the branch offices, support several applications, and have a high performance. The headquarters and two branch offices will use a Virtual Private Network (VPN) connection to the internet and require at least two routers, security gateways, and Ethernet switches at

alternative to traditional mail by sending and receiving electronic documents. • Instant messaging – Supports direct, “live” electronic communication between two or more friends or buddies. • Internet telephone – provides a very low cost alternative to long-distance telephone calls using electronic voice delivery. • Electronic commerce – buying and selling goods electronically In this chapter, we will focus on the communication systems

incorporated. In short, individual rights groups, governments and Internet Service Providers (ISPs) all have different proposals for what net neutrality is to them. The debate of Net Neutrality is much about keeping the Internet where it is now or how much to allow ISPs, specifically broadband providers, to manage their specific networks. However, this debate is more political than technical, therefore the issue is the Internet has grown so large and to the point that the government is now involved

A Performance Analysis OF VoIP Traffic Over Wireless Lan And Wan Using Different Codecs Tasnim Abdalla Abbas Mohamed * Dr.Amin Babiker A/ Nabi Mustafa Department Of Communication Engineering .Al-Neelain University ABSTRACT A simulation model is presented to analyze and evaluate the performance of VoIP based integrated wireless LAN/WAN with taking into account various voice encoding schemes. The network model was simulated using OPNET Modeler software. Different parameters that indicate

need to be connected to an email server to send and receive emails e.g. GroupWise email. Internet Relay Chat (IRC) is online instant messaging over the Internet an example of this is MSN chat. It is designed for groups to communicate in discussion boards like channels, online tutors. Users can join the conversation and send messages to it, which shows to all the others users talking in the same chat. Internet Relay chat can be used in organisation when there are meetings or group conversation, everyone

Transmission Control Protocols or TCP is among the key methods utilized in Internet Protocol Suites. TCP has got two end systems, a web browser and a web server from which it operates. TCP provides delivery of a stream of bytes from a program on one computer system to another. Internet Protocols operate at a lower level compared to TCP. An IP is used for data transmission across a packet switched internetwork. In X on and X off signals, the X means transmitter. These types of signals are used to
