16.  You are installing a network interface card on a computer with the following configuration: a 5867133 CPU, 16MB or RAM, a 800-MB IDE hard disk, a parallel port configured as LPT1, and a serial port configured as COM1, which is currently used by a mouse. In addition to the IDE host adapter and the video card, the following devices have been installed on the computer’s expansion bus: a modem on COM2, a SCSI host adapter for a CD-ROM drive, and a sound card. The SCSI hose adapter is using IRQ 5, and the sound card is using IRQ 11. The network interface card that you are installing supports the following choices for IRQ: 2, 3, 4, 5, 9,10 and 11. Which IRQ(s) could you use for the network interface card without creating an IRQ conflict with another device?

A. 2
B. 4
C. 5
D. 10
E. None of the above

17. Which layers of the OSI model are managed by a network protocol such as Microsoft NetBEUI?

A. network and transport
B. physical and data link
C. transport and session
D. media access control and logical link control
E. None of the above

18. What does the transport protocol do?

A. It defines how data should be presented to the next receiving layer, packages the data accordingly, and then passes the data to the application through the session layer interface.
B. It provides low-level access to the network adapters by providing data transmission support and some basic adapter management functions
C. It supports communications between applications on different computers by creating sessions, defining data-exchange formats, and providing application-support services
D. It is responsible for establishing logical names on the network, establishing connections between two logical names on the network, and supporting reliable data transfer between computers that have established a session
E. None of the above

19. Bridges operate at the MAC layer (layer 2 of the OSI model.)

A. True
B. False

20. You need to install network adapters in 20 ISA-bus computers. Which rule must you follow when installing the network adapters?

A. All adapters in a computer, including the network adapter, must be set to the same IRQ
B. All adapters in a computer, including the network adapter, must be set to different IRQs
C. All network adapters in all computers on the same network must be set to the same IRQ
D. All network adapters in all computers on the same network must be set to different IRQs
E. None of the above
