1[blank_start]Routers[blank_end] provide connections to [blank_start]wide area network[blank_end] services, as well via a [blank_start]serial[blank_end] interface for WAN connections – specifically, V.35 physical interface on a Cisco router.
- Awide area network
- BRouters
- Cserial
2[blank_start]Routers[blank_end] are basically employed to efficiently break up a broadcast [blank_start]domain[blank_end].
- ARouters
- Bdomain
3A [blank_start]switch[blank_end] can break up collision domains.
- Aswitch
4Any networking neighborhood environments, all of this is carried out using devices like [blank_start]routers[blank_end], switches, and [blank_start]bridges[blank_end].
- Arouters
- Bbridges
5When a [blank_start]host[blank_end] or server sends a network broadcast, every device on the network must [blank_start]read[blank_end] and process that broadcast – unless you have a [blank_start]router[blank_end].
- Ahost
- Bread
- Crouter
6Even though routers are known for breaking up [blank_start]broadcast[blank_end] domains by default, it is important to remember that they break up collision [blank_start]domains[blank_end] as well.
- Abroadcast
- Bdomains
7Routers do not forward broadcast by [blank_start]default[blank_end], they also can filter the network based on layer [blank_start]3[blank_end], network layer, information such as an [blank_start]IP address[blank_end].
- Adefault
- B3
- CIP address
8It is helpful to think as routers as [blank_start]layer 3[blank_end] switches.
- Alayer 3
9Unlike plain – vanilla layer 2 switches, which [blank_start]forward[blank_end] or filter [blank_start]frames[blank_end], [blank_start]routers[blank_end] or layer 3 switches use logical addressing and provide an important capacity called [blank_start]packet[blank_end] switching.
- Aforward
- Bframes
- Crouters
- Dpacket
10Routers can also provide packet [blank_start]filtering[blank_end] via access list, and when routers connect two or more networks together and use [blank_start]logical addressing[blank_end] you then have an Internetwork.
- Afiltering
- Blogical addressing
11Routers use a [blank_start]routing[blank_end] table, which is essentially a [blank_start]map[blank_end] of the internetwork, to make best Pat selections for getting data to its proper destination and properly [blank_start]forward[blank_end] packets to remote networks.
- Arouting
- Bmap
- Cforward
12We don't use [blank_start]layer 2[blank_end] switches to create internetworks because they don't break up [blank_start]broadcast[blank_end] domains by [blank_start]default[blank_end]. Instead they are employed to add functionality to a network [blank_start]LAN[blank_end].
- Alayer 2
- Bbroadcast
- Cdefault
- DLAN
13Switches don't forward packets to other networks like [blank_start]routers[blank_end] do. Instead, they only switched [blank_start]frames[blank_end] from one port to another within the [blank_start]switched[blank_end] network.
- Arouters
- Bframes
- Cswitched
14Switches [blank_start]break up[blank_end] collision domains.
- Abreak up
15[blank_start]Collision[blank_end] domain is an ethernet term used to describe a network scenario in which one device sends a [blank_start]packet[blank_end] out on a network segment and every other device on the same [blank_start]segment[blank_end] is forced to pay attention no matter what.
- ACollision
- Bpacket
- Csegment
16Each and every [blank_start]port[blank_end] on a switch represents its own collision domain, allowing network traffic to [blank_start]flow[blank_end] much more smoothly.
- Aport
- Bflow
17Switches create [blank_start]separate[blank_end] collision domains within a single broadcast domain. Routers provide a separate [blank_start]broadcast[blank_end] domain for each interface.
- Aseparate
- Bbroadcast
18[blank_start]Bridges[blank_end] and switches basically do the same thing – breakup [blank_start]collision[blank_end] domains on a LAN.
- ABridges
- Bcollision
19You would use a [blank_start]bridge[blank_end] in a network to [blank_start]reduce[blank_end] collisions within broadcast domains and to [blank_start]increase[blank_end] the number of collision domains in your network. Doing this provides more [blank_start]bandwidth[blank_end] to users. And never forget that using hubs in your ethernet network can contribute to congestion. Plan your network design carefully
- Abridge
- Breduce
- Cincrease
- Dbandwidth
20The three interconnected hubs at the bottom of the figure also connect to the [blank_start]router[blank_end]. This setup creates one [blank_start]collision[blank_end] domain and one broadcast domain and makes that bridge network, within its two [blank_start]collision[blank_end] domains, looked majorly better by contrast.
- Arouter
- Bcollision
- Ccollision
21Typically don't require NID's on [blank_start]MPLS[blank_end] circuits
- AMPLS
22A packet contains [blank_start]IP addresses[blank_end].
- AIP addresses
