- 3. You are setting up a network in a school. You need to network 5 computers for the file and printer sharing. You want to use some donated cable and Ethernet adapters. You identify the donated adapters as ARCnet coaxial network adapters and 10Base2 Ethernet network adapters. You install an Ethernet adapter in each of the 5 computers and connect the donated cable. The computers are NOT able to maintain reliable communication. You suspect that you are NOT using the correct type of coaxial cable. Which type of coaxial cable should you be using?
Options- A. RG-58 AU
- B. RG-59 AU
- C. RJ-11
- D. RJ-45
- E. None of the above Discuss
- 4. 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?
Options- A. 2
- B. 4
- C. 5
- D. 10
- E. None of the above Discuss
- 5. Why does a high number of broadcast messages adversely affect overall network performance?

- C. Broadcast messages are automatically routed to every segment of a LAN
- D. Every computer on the network must process each broadcast message
- E. None of the above Discuss
