Chapter 7, Problem 1RQ

Explanation of Solution

 Features of simple network:

  • The client computers, server computer, network operating system software, network interfaces, hub, and a connection medium are the entities of a simple network.
  • The basic responsibility of network operating system software is to control the network and its functions.
  • One client computer is connected to another client computer within the same network.
  • Hubs and switches function are to send packets of data to all other linked devices.
  • The network helps web pages to store data and network operating system.
  • The switch has the capability to select a particular destination while the hub sends a packet to all other linked devices.
  • The network components links with the connection mediums such as coaxial cables, radio signals or telephone wires.
  • The Microsoft Window Server, Linux and Novell Open Enterprise Server are the most commonly used network operating system software...

Explanation of Solution

Principal technologies and trends:

 Some of the principal technologies and trends which have shaped contemporary telecommunications systems are as follows:

  • Client/ Server computing
  • Packet switching
  • TCP/ IP and Connectivity

    Client/ Server computing:

  • Client/ Server computing is defined as a distributed computing model where a part of the processing power is placed within cheap client computers and exist in laptops, handled devices or desktops.
  • It also allows for computing to departments, factory floors, workgroups and other parts of a business that couldn’t be worked by a centralized architecture.
  • The clients are linked to other clients through networks that is controlled by a network server computer.
  • It has replaced by centralized mainframe computer.
  • The process of the client/ server computing has no longer taken place on a central large mainframe computer.

Packet Switching:

  • Messages transferring in the internet are divided into fixed size unit of data called packets.
    • Messages are divided into packets to increase the performance and reliability of the internet.
    • Ιt also improves the effectiveness of the communication line in the internet.
  • Packets travel through several routers before it reaches the destination...
