1. A device that acts as a connection point between computers and that can filter and forward data to a specified destination is called a (Points : 1)         hub.

2. Which device sends data packets to all connected devices in a network? (Points : 1)         Network interface card
       None of the above |

3. The method of slicing digital messages into parcels, transmitting them along different communication paths, and reassembling them at their destination is called (Points : 1)         multiplexing.

       packet switching.
       packet routing.
       ATM. |

4. What is the most important communication standard today for linking disparate computers and networks? (Points : 1)         Transmission Control Protocol/Internet Protocol (TCP/IP)        International Standards Organization (ISO)

       Open Systems Interconnection (OSI)
       File Transfer Protocol (FTP) |

5. In TCP/IP, IP is responsible for (Points : 1) 
       disassembling and reassembling packets during transmission.        establishing an Internet connection between two computers.        moving packets over the network.
       sequencing the transfer of packets. |

6. On which protocol is the Internet based? (Points : 1)         TCP/IP
       Packet switching
       Frame relay |

7. All network computers connect to a single hub in a (Points : 1)         star network.
       bus network.
       domain network.
       peer-to-peer network. |

8. In a bus network, (Points : 1) 
       signals are broadcast to the next station.
       signals are broadcast in both directions to the entire network.        multiple hubs are organized in a hierarchy.
       messages pass from computer to computer in a loop. |

9. A network that covers a large geographic area is most commonly referred to as a(n) (Points : 1)         local area network .
