P a g e | 1 ASSIGNMENT 1 ANSWERS INTRODUCTION TO NETWORKING Networking is referred as connecting computers electronically for the purpose of sharing information

. Resources such as files , applications , printers and software are common information shared in a networking. The advantage of networking can be seen clearly in terms of security , efficiency , manageability and cost effectiveness as it allows collaboration between users in a wide range. Basically , network consists of hardware component such as computer , hubs , switches , routers and other devices which form the network infrastructure. These are the devices that play an important role in data transfer from one place to another using different technology such as radio waves and wires. There are many types of network available in the networking industries and the most common network are Local Area Network ( LAN ) and Wide Area Network ( WAN ) .LAN network is made up of two or more computers connected together in a short distance usually at home , office buildings or school. WAN is a network that covers wider area than LAN and usually covers cities , countries and the whole world. Several major LAN can be connect together to form a WAN. As several devices are connected to network , it is important to ensure data collision does not happened when this devices attempt to use date channel simultaneously. A set of rules called Carrier Sense Multiple Access / Collision detection are used to detect and prevent collision in networks. **P1 Discuss the benefits and constraints of different network types and standards.

  1. What is the network?**
  • A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.

P a g e | 3 100 to 100Mbps.

  • LANs are not limited to wire connection, there is a new evolution to the LANs that allows local area network to work on a wireless connection. Figure 3 LAN ( Local Area Network) 2.2. MAN ( Metropolitan Area Network)
  • MAN network covers larger area by connections LANs to a larger network of computers. In Metropolitan area network various Local area networks are connected with each other through telephone lines. The size of the Metropolitan area network is larger than LANs and smaller than WANs(wide area networks), a MANs covers the larger area of a city or town. Figure 4 MAN (Metropolitan Area Network)

P a g e | 4 2.3. INTERNET ( International Network)

  • The Internet is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. Figure 5 INTERNET ( Internetnational Network) 2.4. Benefit of networking 2.4.1. Advantages of LANData Security : Data security is easy in LAN because all the computers are connected to the server system and all the data is stored at one place in the server so easy to maintain secured too.

P a g e | 6  Data is easy to backup as all the data is stored on the file server. 2.5. Protocol and Standards 2.5.1. Define Standards

  • A standard is a set of specifications for hardware or software, agreed upon by academic and industry contributors. A standard makes it possible for many manufacturers to create products that are compatible with each other. Standards may be set by official organizations, or unofficially set, established by common use. Common examples of standards include multiple IEEE standards for electrical interfaces (computer cables), ANSI for programming languages, and VESA for computer monitors and video adapters. 2.5.2. List some protocols
  • There are various types of protocols that support a major and compassionate role in communicating with different devices across the network. These are:

+ Transmission Control Protocol (TCP)

+ Internet Protocol (IP)

+ User Datagram Protocol (UDP)

+ Post office Protocol (POP)

+ Simple mail transport Protocol (SMTP)

+ File Transfer Protocol (FTP)

+ Hyper Text Transfer Protocol (HTTP)

+ Hyper Text Transfer Protocol Secure (HTTPS)

2.5.3. List some standard organizations and standards names  3GPP – 3rd Generation Partnership Project  3GPP2 – 3rd Generation Partnership Project 2  ABYC – The American Boat & Yacht Council (ABYC is an international organization, despite its name)

P a g e | 7  Accellera – Accellera Organization  A4L – Access for Learning Community (formerly known as the Schools Interoperability Framework)  AES – Audio Engineering Society  AHRI - Air-conditioning, Heating, and Refrigeration Institute  AIIM – Association for Information and Image Management  ASAM – Association for Automation and Measuring Systems  ASHRAE – American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE is an international organization, despite its name)  ASME – American Society of Mechanical Engineers  ASTM International P2. Network topology & communication and Bandwidth requirements

1. What is Network topology? 1.1. Network topology definition. - Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, industrial fieldbusses and computer networks. - Network topology is the topological structure of a network and may be depicted physically or logically. It is an application of graph theory wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes.
