What is the drawback of the CSMA access method?
Collisions can decrease network performance.
Disadvantage of using network-level broadcast to locate resources in a single Ethernet?
what is networking & operating system
Which port should you connect a router to a lan?
It shouldn't matter which port you use unless it involves a network switch.
What is ethernet cable?
Ethernet cable is typically 8-core category 5 (CAT5) cable with RJ45 plugs on each end, capable of bi-directional network transmission up to 100m. CAT5e and CAT6 are better quality cable for network communications over longer distances.
Why does each workstation need a network card?
Because without the network card in the work station it would have no way to communicate with the central server which probably stores all the information centrally, obviously. It is also related to the sharing of printers and the internet around in the network. Therefore the use of the network card is to allow communication between the work station and the server via ethernet cables and network bridges. These could also be wireless meaning cableing would not be needed, but are not as quick or reliable, and also has a far greater risk of getting hacked into the network.
What characteristic to an Ethernet network using hubs does using an Ethernet switch minimize or avoid?
Collisions
What is the function of CSMA CA on a wireless Ethernet network?
To prevent collisions.
What happens when you plugin the Ethernet cable to your PC?
when ethernet cable is plugged in it is detected by ethernet card. if the cable is connected to network it detects that network and dispalys " you are connected to network"
Which 2 might cause excessive data collisions on an ethernet network?
The overall network length exceeds IEEE 802.3 standards for that network type.A server on the network contains a faulty NIC.
Which of the two following might cause excessive data collisions on a ethernet network?
Excessive broadcasts, and using hubs instead of switches or routers to segment the network.
Which network control protocol is used to prevent collisions on a full duplex network?
Full Duplex Ethernet uses no network control protocal to prevent collisions. This is because full duplex has a deicated channell for transmit and receive. When communicating in full duplex mode, there is no area to have a collision.
What symptoms would probably be present if your 100 Base TX Ethernet network length is 200 meters?
B. Excessive late collisions
What if your network is configured as a single IP subnet Multiple hubs are connected to an Ethernet backbone You need to reduce the number of collisions on the network.What should you do?
Install a switch.
What is the first thing that happens when a collisions occurs in an Ethernet network?
When a collision occurs, the stations back off and stop transmitting. After a randomly chosen period of delay, the data is resent.
What are late collisions?
Late collisions are collisions that happen after the first 512 bits of the ethernet frame. These losses are not recovered by the network layer; it is up to the higher protocols to rerequest data if any was lost. The most common cause by far is a duplex mismatch. Check to be sure both sides of the connection agree on either half-duplex or full-duplex. Other causes include cable lengths exceeding the 100-meter standard, a inappropriately large number of hubs in the network, or faulty ethernet cards.
A sentence for protocol?
Most network cards nowadays use the Ethernet protocol.Most network cards nowadays use the Ethernet protocol.Most network cards nowadays use the Ethernet protocol.Most network cards nowadays use the Ethernet protocol.
What are two problems that might cause excessive data collisions on an ethernet network?
Too many computers connected, and trying to transmit at the same time; and the use of switches instead of hubs.
