Flashcards in Wk6_chapter 4 questions and answers Deck (55):
A UTP's category will determine the maximum number of bits it can transmit.
With a standard bus topology, contention and collision are defining characteristics.
Troubleshooting tools are based on software only.
A topology has only physical characteristics.
An Ethernet MAC address is usually specified in:
The IEEE formalized the ring topology as the 802.3.
In a peer-to-peer TCP/IP LAN, a host might serve as a client, a server, or both.
NICs supporting different Mbps capacity could be used in a 100BaseTX LAN.
The maximum length of a standard Cat 5 segment:
A star topology has a central controlling device.
A LAN that uses dedicated servers is called a peer-to-peer LAN.
A bus topology forms a closed loop.
A NIC is always internal to the device, connecting to the device's motherboard.
Cost has helped make 802.3 the first choice for most LAN topologies.
Client devices that connect to a network require:
both a physical address and a logical network address
Cache memory is usually slower than hard drive access.
An advantage of a physical and logical star topology is that it:
centralizes management of network resources
A NIC is also referred to as a:
Wiring closets are usually physically secured.
Category 5 cable should be used in segments of no more than 100 feet.
LAN resources might include:
all of the following: hardware, software, data
NICs are an optional component of each device in a network.
In a switching hierarchy, a frame could take more than one path from source to destination.
The protocol associated with the bus topology:
LAN components are physical and logical.
Compared to standard servers, blade servers are generally:
smaller and consume less power
Terminals are often associated with the classic star topology.
A physical star could also be a logical:
star or ring
Hardware devices often have a logical component called a:
The digits in an Ethernet MAC address that specify the internal serial number:
A 32-bit bus can handle ________ times the data bits as an 8-bit bus.
Routers have displaced many switches in modern networks.
Eight bits as a unit is an octet.
In the past, devices connected to a mini- or mainframe computer through:
do not require specialized server software
Fast Ethernet LANs that use switches can be greater than 250 meters in diameter.
Term used to describe a signal that is recreated at its original strength:
A higher cable category represents a smaller cable size.
Physical components are frequently referred to as:
Two hard drives that share the same controller may be performing:
A 802.5 network utilizes a device called a:
Switches, in general, cost less than routers.
Server primary memory is also referred to as buffer or cache memory.
Switches create dedicated circuits for the devices connected to them.
Two or more NICs, by design or intent, often have the same physical address.
Servers typically fulfill a generalized, nonspecific function.
A topology's physical and logical characteristics are always the same.
Ethernet is the most common topology used in LANs today.
Reduced resistance translates into slower transmission speeds.
A key indicator of LAN performance is response time to a request.
A bus topology:
all of the following: views its circuit as a single cable, des not form a closed loop, is often associated with ethernet
Physical components are frequently referred to as hardware.
Hard drive access speed can affect a server's performance.
A network login generally requires:
only a suer id and only a password
