1. What are the four generic architectural components of a public communications network? Define each term? The Generic architectural Components are Subscribers, Subscriber Line, Exchanges and Trunks. Subscribers: The gadgets that connect to the system, for example, phones and modems. Subscriber Line: The link between the subscriber and the network. Exchanges: The exchanging focuses in the system. Trunks: The branches between trades. Trunks convey numerous voice-recurrence circuits…

1. What provides the physical connection between workstations on the network? The cables/wires and network interface card (NIC) provide the physical connection between work stations on the network. 2. What directs the flow of data over the network? A switch/hub/router directs the flow of data over the network. 3. What are the three functions of network software? The three functions of the network software are: To make sure that the information is addressed properly. To organise information…

number of hosts connected to the public Internet, a confederation of networks looking much like today’s Internet, would reach a hundred thousand. The 1980s would be a time of tremendous growth. Much of that growth resulted from several distinct efforts to create computer networks linking universities together. BITNET provided e-mail and file transfers among several universities in the Northeast. CSNET (computer science network) was formed to link university researchers who did not have access to…

The Key Concepts of Network Configuration Network configuration starts with a device such as a computer, each device requires the assignment a unique number to identify it on the network, known as an IP address which stands for Internet Protocol Address. Every device requires an IP address from a cell phone to a fax machine. This number gives your device the ability to communicate with other devices and available networks. Once the original device requires network access to another device,…

as Neural Networks. There have been many other cases like ours that have used Random Forest. Nantian Huang, Guobo Lu and Dianguo Xu have been one of the many who have used Random Forest and succeeded. In their paper, “A permutation importance based feature selection method for short term electricity load forecasting using Random Forest,” they talk about how they got load forecast through predictions. Load Forecast, is the planning, operating and scheduling of traditional power networks. The…

SDN are next generation networks. They provide high flexibility, reliability, and security. The main difference between SDN and the traditional network is separation of control and data plane. In SDN, only the controller has the decision-making capabilities. Whereas switches are responsible for traffic forwarding. The controller and switches can be programmed dynamically or as needed. Applications communicate directly with the SDN controller via the northbound interface. This plane is also…

Q1.Ethernet has become the standard for LAN communications. Give a brief overview of structure of an Ethernet frame. Ethernet and Wi-Fi are the most commonly used technologies to set up Local Area Networks today. It operates by using Carrier Sense Multiple Access Detection (CSMA/CD) to control media access. (Study CCNA, 2016) The structure of an Ethernet Frame is as follows: The Ethernet Frame Structure (Anon., 2013) Explanation: • Preamble: This field is responsible for harmonizing bits…

Since their introduction, social networks such as Facebook, Twitter, Instagram, and Myspace have attracted millions. Leading to many users having it integrated in their schedules for a daily visit. The technological side of social networks have advanced tremendously throughout the years. Social networks have always kept it easy for users to grasp the concept of understanding how to use it. It helps for strangers and friends to keep connected through common interest and information about…

people buying from home make the need for clerks and cashiers fewer causing a decline in employment. For some businesses like Walmart they’ve cornered the market by covering all areas in person and online, taking advantage once again with social networks and appealing to wireless…

are shocked that Arabians, Africans, rural Asians, Mexicans, Central and South Americans actually have social network accounts. Social networking in third world countries is more of a tool than a pastime. To start, citizens of third-world countries have less access to the Internet than those…
