Quick Tips 3 Flashcards
A BLANK is a device with combined repeater and bridge technology. It works at the BLANK layer and understands MAC addresses.
switch, data link
BLANK link two or more network segments, where each segment can function as an independent network. A BLANK works at the network layer, works with IP addresses, and has more network knowledge than bridges, switches, or repeaters.
Routers, router
A BLANK filters by MAC addresses and forwards broadcast traffic. A BLANK filters by IP addresses and does not forward broadcast traffic.
bridge, router
BLANK switching combines switching and routing technology.
Layer 3
BLANK is the loss of signal strength when a cable exceeds its maximum length.
Attenuation
BLANK and BLANK are twisted-pair cabling types that are the most popular, cheapest, and easiest to work with. However, they are the easiest to tap into, have crosstalk issues, and are vulnerable to EMI and RFI.
STP, UTP
BLANK carries data as light waves, is expensive, can transmit data at high speeds, is difficult to tap into, and is resistant to EMI and RFI. If security is extremely important, fiber-optic cabling should be used.
Fiber-optic cabling
BLANK transfers data in fixed cells, is a WAN technology, and transmits data at very high rates. It supports voice, data, and video applications.
ATM
BLANK is a LAN and MAN technology, usually used for backbones, that uses token-passing technology and has redundant rings in case the primary ring goes down.
FDDI
BLANK, 802.5, is an older LAN implementation that uses a token-passing technology.
Token Ring
Ethernet uses BLANK, which means all computers compete for the shared network cable, listen to learn when they can transmit data, and are susceptible to data collisions.
CSMA/CD
BLANK technologies set up a circuit that will be used during a data transmission session. BLANK technologies do not set up circuits— instead, packets can travel along many different routes to arrive at the same destination.
Circuit-switching, Packet-switching
BLANK has a BRI rate that uses two B channels and one D channel, and a PRI rate that uses up to 23 B channels and one D channel. They support voice, data, and video.
ISDN
BLANK is an encapsulation protocol for telecommunication connections. It replaced SLIP and is ideal for connecting different types of devices over serial lines.
PPP
BLANK sends credentials in cleartext, and CHAP authenticates using a challenge/response mechanism and therefore does not send passwords over the network.
