Essays on Data Rate

The paper deals with the evolution of GSM networks from the simple circuit switched networks to the contemporary third generation of mobile communications which is based on packet switching. Throughout the paper, the third generation of mobile communication is denoted by 3G, as it is denoted in the technical field.

The main contents of this article give an overview of how mobile technology has evolved over time and as it has been witnessed in many technologies, the successor generation has some improvements on the problems noted in the predecessor. This is witnessed by interoperability in 3G which was a ...

Introduction

ADSL (Asymmetric Digital Subscriber Line) is a modem technology that is available channel bandwidth is shared between the outgoing and incoming traffic is asymmetric. Since most users have incoming traffic volume is much higher than the volume of outgoing, the rate of outgoing traffic is significantly lower. This restriction was uncomfortable with the spread of peer-to-peer networks and video.

History of development

History of the development of ADSL technology started in the second half of the eighties, when were searching technology for interactive television. Pioneer family of technologies xDSL is a company Bellcore; in 1987, it introduced the first specification of a family of technologies ...

- Explain how WiMAX will make a difference in how we “connect” to the Internet. What are some of its key characteristics? (TC) WIMAX is short for worldwide interoperability for microwave access. It has a potential of broadband internet access. It does not require cable and this enables people to connect to the internet automatically wherever they are. This is possible through the availability of WIMAX antenna. - Briefly discuss the differences and the role of each of these wireless standards: Bluetooth, Zigbee, 802.11b Bluetooth is a wireless technology for connecting devices. The devices have to agree before they ...

Wi-Fi Wi-Fi is an acronym for Wireless Fidelity. It is a groundbreaking invention in the field of networking and has been finding increasing uses everyday. Based on IEEE 802.11a/g, current Wi-Fi systems support a maximum data rate of up to 54mbps. There are different features and aspects of this technology, which define it and its applications. Some of the most important and prominent uses of Wi-Fi Technologies are: Based on Radio Signals: Radio Signals form the basis of operations for the Wi-Fi technology. The data is transmitted through these radio signals from one Wi-Fi enabled device to the other. ...

Chronologically from the first generation of telephony (1G) that carried only analog voice data, to the current fourth generation (4G) of mobile technology, telecommunications have evolved over the years to cater for the growing networking demands of present day mobile communications users. Each generation has been developed building upon the previous technology to improve on it in order to deliver better services. The generations (G) specify the classes of technology, each having its own data rates and devices associated with it. - EVOLUTION OF MOBILE COMMUNICATION NETWORKS The 1G cellular networks started in the early 1980s and ...

ABSTRACT

This proposal highlights the suggested changes to improve the efficiency and throughput of the computer network of Ocper Inc. The changes proposed will implement a client/server model in a Local Area Network (LAN) in replacement of the existing Peer-2-Peer network. A change of the connecting cables from coaxial cable to unshielded twisted pair cable is also suggested.

In the currently used peer-to-peer connection, there is no dedicated computer to provide services to the other computers. Also, the expected growth of the existing 20 computers will reduce the throughput of the network with this topology, since the network will become slow and ...

Packet switching refers to a digital networking communications method in which all the data transmitted is grouped into blocks called packets before it is sent. Packet switching applies to all transmitted regardless of its type, content or structure. The data is transmitted over a shared network and transverses through a network of switches, adapters, routers and other network nodes (OPTNET Technologies, 2010). Packets of data are transmitted individually to their destination using different routes. Once all the packets forming a message get to the destination they re-compile into the original message. Common protocols using the packet switching technologies include Wide Area Network (WAN) ...

Introduction Have to send an urgent mail, and you are in a flight or train with no internet connectivity. Want to link your devices, access mails when you not at desk, etc., Bluetooth and Wi-Fi could be the solution to this. These are the two terms which are known and common to all of us today. Bluetooth and Wi-Fi is a technology that allows one to access information and connect to devices and peripherals without wires and cables. Hence it is hassle free and convenient usage for the people as it allows one to operate freely with your resources within a ...

CPU and RAM There are many components that make up a computer system. The core unit is central processing unit. This is the most important component as it is tasked overall processing of information in all the other components. Another important component is the memory. A computer with a good memory but low memory will not be that powerful. These two computer components have undergone a long process up to where they are. They are becoming more powerful and smaller. This paper will look at the technologies behind these two computer components.
