Topology

no difference,,,tree and hybrid are same.

The advantage is in fault detection; in a bus topology any break in any wire segment would cause the entire LAN to fail. With a star topology, a break in any wire segment only affects the one client connected to the network.

a topology is a way to connect the network system. we can connect network with different types ring ,bus and mash is a topology or way to show connect network with different types in ring topology the systems which we want to connect in network in the form of ring

Power over ethernet (PoE)

Yes...depending on the type of topology.

true

Topology deals with the mathematical properties of shapes.

both hubs and switch can act as a center of a star topology

Bus

Daisy chaining is a term used to denote that one system is directly connected to the next system without any intervening devices. It is usually reserved for linear bus topologies in a network, but can be applied to other things as well, such as SCSI disk hard drives which can be chained together.

This answer assumes you are asking about a token ring network. I don't know about any other 'token bus topology'. You can think of this as a group of people (say 10 people) standing in a circle. An (one) envelope is being passed from one person to the next. There is not a "From" or "To" address on the envelope. So it comes in on the left hand (received) and is passed out by the right hand to the next (transmitted) person, ad infinitum. A token ring is a serial topology - a message has to passed from one station to the next. The message is seen at a station. and if the addressing in the message block matches it's addrress, the information within the message is removed and retained by that station, and the rest of the package (token) is transmitted on to the next station. Of course there is no info in there for this next station, so it just re-transmits on, and this package is passed around, and around, and around. If a station has someting to transmit out, i.e. a browser request or a file request to a network drive, etc, it waits until the empty token get around to it, captures the token to put in the addressing and message blocks, then transmits. The appropriate gateway will capture it for a browser request, or a server will intercept it for a file request. Again - notice this is a serial topology, one station after the next. But it is quick - either 4 or 16 Mbps. Since it is serial, there should never be a colision, and it should be very reliable, very fast. Unfortunately, the connectors for the cables at the wall stand out pretty proud, and are prone to getting bumped, knocked, kicked out of the wall connection. They are designed to not break the ring if this happens, but of course, that station is off line (same as removing the enet cable connector from the wall).

Star topology.

One of the most popular topologies for Ethernet LANs is the star and extended star topology. It is easy to setup, it's relatively cheap, and it creates more redundancy than the Bus Topology. The Star Topology works by connecting each node to a central device. This central connection allows us to have a fully functioning network even when other devices fail. The only real threat to this topology is that if the central device goes down, so does the entire network. The Extended Star Topology is a bit more advanced. Instead of connecting all devices to a central unit, we have sub-central devices added to the mix. This allows more functionality for organization and subnetting- yet also creates more points of failure. In many cases it is impractical to use a Star Topology since networks can span an entire building. In this case, the Extended Star Topology is all but necessary to prevent degraded signals. Whereas the Star Topology is better suited for small networks, the Extended Star Topology is generally better for the larger ones.

hi

i am not sure but its ring topoloy

A Local Area Network (LAN) may use many different types of topologies (how the network is physically wired). If one uses a ring topology, then a special type of managed hub is usually used which implements packet switching in a round, ring structure, in which each station is visited by the packet in linear sequence.

Ring topologies also involve the use of a 'token', which describes whether a station on the ring may use the network or not.

Ring topology can be considered as a LAN and it is rarely used nowadays.

there are a few different topologies when you are talking about WAN's but remember WAN's topologies are different than LAN's because of the area they cover. But there are bus wan, ring wan, star wan, full mesh wan, partial mesh wan, and tiered wan.

as far as a drawback to bus topology is that each site in the wan bus topolgy depends on every other site in the network to transmit and receive its traffic.

yes

All common topologies allow for computers to be arranged in a physical line.

The three most common are ring, star, and bus.

Here is a simple picture of the networks.

Rj-45 is the most common type of cabling. RJ-45 refers to the terminator (connector) on the end of the cable, and the jack it plugs into--more specifically RJ-45M and RJ-45F, respectively. The associated cabling will be CAT(category)-5 or CAT-5e(enhanced), which are in the class of Unshielded Twisted Pair. A star network is typified by the hub or switch, with a cable running from it to every device on the network. Other cabling might be used, but CAT-5 is far and away most common.

A switch topology is an organizational representation of the channels and relays in a switch module. The topology establishes the default states for all relays in a module and defines the channel names. Some switches can use multiple topologies or variations of each topology type. Some terminal blocks or accessories may force the switch to use a given topology or set of topologies. GHOUL

A star-wired bus is a hybrid topology (more than 1 type of topology). There is no particular access method that requires or relies on that type of hybrid.

topologi star merupakan salah satu topologi dalam sistem internet atau jaringan sehingga antara komputer server dan komputer klien saling berhubungan. dimana topoligi star banyak digunakan dalam jaringan LAN maupun WAN. selain mudah dalam instalasinya, topologi star tidak memerlukan banyak komponen pendukung serta hemat dalam segi biaya.
