Public switched telephone network

For part B of assignment 1, i shall discuss the process and technical details involved with performing a telephone call from a Desktop Pc, to a telephone. I shall run through the process, using Alice (digital Device owner) and Bob (telephone) to describe the process. Before we can begin the call, the pc requires both a microphone and headset/speakers to be able to run any call, and a pc with a fast enough connection to the internet. In this instance, the call will be running as a two way communication known as duplex, which allows the transmission and receiving of information from two connected parties. This means that both connected callers can talk via their microphones and listen from the speaker simultaneously. The best way to describe it is that…

automated and requires very little user input. Considering A as the caller, B as the receiver, and C as the attacker who tries to spoof A’s caller identification while calling B. In such a spoofing scenario, A may not be in B’s contact list (unknown), and A’s number could be invalid (unreachable). Since the verification operation is preformed automatically, we expand our definition of the names and refer A, B, and C to the devices of caller, receiver and attacker respectively. In addition A, B,…

CDMA is a service that provide all the communication overall and it also provide in major service in network capacity. CDMA service is mostly used in Cell phone and it can be easily be used for communicating terminal with two base stations. CDMA is a form of multiplexing, which allow a number of signals to work on a single transmission channel and also boost the use of available bandwidth. CDMA has been used in all upcoming generation of Technology system in one form and has a benefit the…

Computer networks LAN – Is a Local Area Network which is a computer network that covers a small area which is sometimes a single room, an office building or a group of buildings. A local area network can be connected with others over a distance for example a telephone line, a radio or a mobile phone call, as a LAN is a network that covers the geographic distance that also involves internet links. A system of LANs that are all connected together is called a WAN, which is a wide area network.…

The following are the important uses and benefits of a computer network - • File/Hardware sharing - Networking of ICT technology helping the network users to share such things. Without using computer networks, this sharing is not possible. • Application sharing - Allows to implement client/server applications. • User communication - Networks allowing users to communicate to each other, for example; Using e-mail, newsgroups, and video conferencing. • Voice over IP - Voice over is a modern change…

Introduction Voice over Internet protocol (VoIP) or IP telephony is the name for a multimedia application that involves streaming audio between users through IP networks. Audio is digitized and sent across IP networks and then converted again to a playable format. It is rapidly growing in popularity due to its cost-saving nature. While there are a variety challenges that need to be overcome in order to make use of this technology widespread, VoIP has the potential to replace traditional phone…
