How does the network layer in a connection-oriented packet-switching network differ from the network layer in a connectionless packet switching network?
An upper-layer packet is split into 10 frames, each of which has an 80 percent chance of arriving undamaged. If no error control is done by the data link protocol, how many times must the message be sent on average to get the entire thing through? An connection-oriented service (like TCP) does error checking and requests data to be resend. The packet has several options for error free transport. Connectionless service (think UDP) does not check for undamaged arival. It has a much smaller packet size and is also faster.

What Reduces interference on a network?
Switching channels on the router or access point will reduce interference on a network.
What network device uses a MAC address table to segment network?
Although some would suggest that a switch could segment a network (and it does use the MAC address for switching) more properly a bridge would be the answer if you are speaking of segmenting a network.
Which switching type will allow the communication devices in the provider network to be shared and only allocated to an individual subscriber during data transfer?
packet-switched
What are the four generic architectural components of a public communication network?
Subscribers: the devices that attach to the network, such as telephones and modems. Subscriber line: the link between the subscriber and the network. Exchanges: the switching centers in the network. Trunks: the branches between exchanges. Trunks carry multiple voice-frequency circuits using either FDM or synchronous TDM. By: khurram, sibbi Pakistan
What is DQDB in computer networks?
In telecommunication, a distributed-queue dual-bus network (DQDB) is a distributed multi-access network that (a) supports integrated communications using a dual bus and distributed queuing, (b) provides access to local or metropolitan area networks, and (c) supports connectionless data transfer, connection-oriented data transfer, and isochronous communications, such as voice communications. IEEE 802.6 is an example of a network providing DQDB access methods.
What is in a connectionless system?
The connection having no physical attachment, or unwired network is called as connectionless system. Examples: The Wi-Fi Network, Bluetooth,etc.
What type of switching does a network use?
circuit switching
What is a function of mobile switching center?
In a network switching subsystem, a mobile switching center is the centerpiece. The function of the mobile switching center is to perform the telephony switching functions and serves as a network node.
What protocols do not guarantee delivery of their data but do operate with a very low overhead that conserves network bandwidth?
connectionless protocols - transport layer
Which protocol provides connectionless network service?
In internet protocol suite UDP is the connectionless protocol. There is no initial communication between client and server. UDP will not check whether the transmission was successful.
Types of network switching?
there are three types of switching techniques 1) circuit switcching 2) Packet switching 3)Message switching
What network technologies use circut switching?
Ethernet
The cost of network is usually determined by what?
switching complexity
What is the advantage of multistage switching network?
it is very cheap
Which network type uses circuit switching?
PSTN
What network requires an access point?
Packet-switching
Define connection oriented and connectionless transmission with examples?
TCP has an acknowledgement technique of checking if data packet is received either at the client or at the server end, this is what makes it a connection oriented network service.whileUDP does not guarantee reliability of ordering or acknowledgement the way TCP does. Datagrams may appear out of order, missing or appear duplicated. This is what makes it a connectionless oriented network service.
