Flashcards in Chapter 1 Deck (26):
what are the common network components?
workstations, servers, hosts.
what is a workstation?
a workstation is a powerful computer that run more then one CPU and whose resources are available to other users on the network to access when need.
list of some common servers?
file server, mail server, print server, web server, fax server , Application server, Telephony server, Remote access server, Proxy server.
what are Hosts?
are network devices, including workstations and servers with IP addresses.
what are some of the things that make WAN different then LAN?
WAN need a routes ports.
WAN spans larger areas.
WAN is slower the LAN.
we can choose how and when to connect to WAN.
in LAN the workstation is ether connected permanently to it or not.
what dose MPLS stand for?
multiprotocol label switching.
What is one of the most WAN protocol in use today?
MPLS is more popular the other WAN's because of what ?
physical layout flexibility.
prioritizing of Data.
Redundancy in case of link failure.
One to many connection.
Network has two types what are they/
Peer to peer
client to server.
What is a peer to Peer?
Peer to Peer is a network that does not have a central computer or dedicated server; in other words, all computers are independent. This network is what you would most likely find in home networks or small networks comprised of a dozen or less computers.
which network type do you have if your network is running windows, Mac or Unix in a LAN?
Peer to Peer
what is Client-Server network?
client/server network. A computer network in which one centralized, powerful computer (called the server) is a hub to which many less powerful personal computers or workstations (called clients) are connected. The clients run programs and access data that are stored on the server. Compare peer-to-peer network.
what is physical network topology?
The physical layout of devices on a network. Every LAN has a topology, or the way that the devices on a network are arranged and how they communicate with each other. The way that the workstations are connected to the network through the actual cables that transmit data, the physical structure of the network is called the physical topology.
some of the network topologies?
Bus, Ring, Stare, Mesh, Point to Point, Point to multipoint, Hybrid.
Bus Topology: In networking a bus is the central cable -- the main wire -- that connects all devices on a local-area network (LAN). It is also called the backbone. This is often used to describe the main network connections composing the Internet. Bus networks are relatively inexpensive and easy to install for small networks.
Main Advantage of Bus topology are:
It's easy to connect a computer or device and typically it requires less cable than a star topology.
Main Disadvantage of Bus topology are:
The entire network shuts down if there is a break in the main wire and it can be difficult to identify the problem if the network shuts down.
In a star network devices are connected to a central point, called a hub, Switch or an access point.
Main Advantage of star topology are:
a single cable failure won't bring down the entire network
-new stations can be added easily.
-easy to troubleshoot.
Main Disadvantage of star topology are;
If the central point fails, the entire network becomes unusable.
it is more expansive because it required more devices.
all of the computers are connected in a closed loop. Messages travel around the ring.
In a mesh topology every device has a connection to every other devices in the network. There are two types of mesh topologies:
1- Full mesh topology: Full mesh is usually reserved for backbone networks.
2- Partial mesh topology: is commonly found in peripheral networks connected to a full meshed backbone.
Full mesh topology redundancy is greatest then Partial mesh topology redundancy. True or false?
point to point topology
The simplest topology with a permanent link between two endpoints.
what are the things you need to put in consideration when selecting the right topology for the right network?
Ease pf installation
ease of maintenance
Fault tolerance requirement
