Chapter 6

1. Networks are systems that are formed by links.

   • Roads that connect groups of people together create a physical network. Connections with your friends create your personal network.
   • . The standards groups create, examine, and update standards. These standards are applied to the development of technology to meet the demands for higher bandwidth, efficient communication, and reliable service

2. Websites that allow individuals to link to each other’s pages are called social networking sites.

3. Networks share information and use various methods to direct the manner in which information flows.

4. A computer network also uses rules to control the flow of data between hosts on a network

5. A host is any device that sends and receives information on the network.

6. A network can share many different types of resources and data:

   • Services, such as printing or scanning
     • Storage space on removable devices, such as hard drives or optical drives
       • Applications, such as databases
         • Information, stored on other computers
           • Documents
             • Calendars, synchronizing between a computer and a smartphone

7. Network devices link together using a variety of connections:

   • Copper cabling - Uses electrical signals to transmit data between devices
     • Fiber-optic cabling - Uses glass or plastic fiber to carry information as light pulses
       • Wireless connection - Uses radio signals, infrared technology, or satellite transmissions

8. In a network, resources can be shared to reduce data duplication and data corruption.

9. Each computer on the network does not need to have its own printer or backup device.

10. Each computer on the network does not need to have its own printer or backup device.

11. The print server can distribute print jobs over multiple printers or queue jobs that require a specific printer.

12. Networks provide several different collaboration tools that can be used to communicate between network users.

13. Networks provide several different collaboration tools that can be used to communicate between network users.

14. Document tracking software can be used to prevent users from overwriting files or changing files that others are accessing at the same time.

15. Standards are used by manufacturers as a basis for developing technology, especially communications and networking technologies

16. Ethernet protocols describe the rules that control how communication occurs on an Ethernet network

17. The IEEE developed standards for manufacturers and programmers to follow when developing Ethernet devices.

18. The Ethernet architecture is based on the IEEE 802.3 standard. The IEEE 802.3 standard specifies that a network implement the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) access control method

19. Electrostatic discharge (ESD), harsh climates, and poor-quality sources of electricity can cause damage to computer equipment

20. ESD occurs when this buildup jumps to a component and causes damage.
