Question

Two new workstations are being added to the office. To connect them to the LAN, they have been equipped with D-Link network interface cards, model DGE-530T. Using the Internet and your research skills (Hint: use D-Link's Web site), determine the following information:

a. Assuming the DGE-530T cards are compatible with the office network, what data link layer standard does the LAN use?
b. What is the name of the access method used on the LAN?
c. What is the maximum transmission speed (transfer rate) supported by this network interface card?
d. What is the name of the interface this network card uses to connect to the computer it is installed in?
e. What type of cable connector does this network interface card support?
f. What type of network cable would you recommend to be used with this connector?
g. The two workstations must be connected to a network hub using patch cables that will connect to a wall outlet. There is already a built in 80 -meter cable connecting the wall outlet to a patch panel and a 12 -meter cable connecting the patch panel to the hub. What is the maximum length of the patch cables that can be used for each of the two workstations?

Answer 1

The D-Link DGE-530T network interface cards support Ethernet IEEE-802.3 at 1 Gbps using the PCIe interface with RJ-45 connectors, and recommend using Cat 5e or Cat 6 cables. The maximum length for patch cables to connect the workstations without exceeding Ethernet's 100-meter limit is 8 meters for each workstation.

Step-by-step explanation:

The D-Link DGE-530T network interface cards are used to connect workstations to a local area network (LAN). On researching the specifications of these cards, we can deduce the following answers to the student's questions:

Answer 2

a. Assuming the DGE-530T cards are compatible with the office network, the LAN likely uses the Ethernet data link layer standard.

b. The access method used on the LAN is likely Carrier Sense Multiple Access with Collision Detection (CSMA/CD).

c. The maximum transmission speed supported by the DGE-530T network interface card is 1000 Mbps (1 Gbps).

d. The network card uses a PCI interface to connect to the computer.

e. The DGE-530T network interface card supports an RJ-45 connector.

f. For this connector, a Category 6 (Cat6) or higher network cable is recommended.

g. Considering the existing cable lengths, the maximum length for each patch cable connecting the workstations to the hub should not exceed 68 meters.

Step-by-step explanation:

a. The DGE-530T is a Gigabit Ethernet card, indicating that the LAN likely uses the Ethernet data link layer standard.

b. Ethernet networks typically use Carrier Sense Multiple Access with Collision Detection (CSMA/CD) as the access method.

c. The DGE-530T supports a maximum transmission speed of 1000 Mbps (1 Gbps).

d. The network card uses a PCI interface for connection to the computer.

e. It supports an RJ-45 connector, which is standard for Ethernet connections.

f. A Category 6 (Cat6) or higher network cable is recommended for optimal performance with this connector.

g. Considering the existing cable lengths, the total cable length for each workstation (including patch cables) should not exceed 68 meters to avoid signal degradation.
