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 are true statements about transport layer protocols?
**The TCP transport layer protocol uses windowing and acknowledgments for reliable transfer of data. **The TCP and UDP port numbers are used by application layer protocols. **The TCP transport layer protocol provides services to direct the data packets to their destination hosts.
What are the applications of ATM networks?
ATM systems use Parcel Switching In telephone arranges, all rates are different of 8 kbps. you can get any rate. You can change your rate with time. With current telephone arranges, all rapid circuits are physically setup. It permits dialing any pace. 125 s 11 it versus Data Networks ATM versus Data Networks IP is connectionless. You can't save data transfer capacity ahead of time. It is association situated. You announce your needs before utilizing the system. Switches can't promise transfer speed or postponement. It systems save transfer speed and supports.
How much data does a optical fiber cable transfer In Megabits per second please?
Optical fibre typically can transmit data at the rate of 1 Gigabit (1024 Megabits) per second
What kind of cable is used to transfer digital video to and from a computer and camcorder?
Transfer cable is used to transfer digital video to and from a computer and camcorder.
Is email connection oriented or connectionless?
Email runs SMTP (simple mail transfer protocol), where SMTP operates over TCP protocol, so it id connection oriented.
Difference between connectionless and connection oriented communication?
Different from a connectionless protocol, a connection-oriented protocol guaranties the delivery of the information. An example of connection-oriented protocol is (TCP) and a connectionless protocol is (UDP). page/926 A+
For which three reason was a packet switched connectionless data communications technology used when developing the internet?
It can rapidly adapt to the loss of data transmission facilities.It efficiently utilizes the network infrastructure to transfer data./
What is the differences between connection-oriented services and connectionless services?
In general, transport protocols can be characterized as being either connection-oriented or connectionless. Connection-oriented services must first establish a connection with the desired service before passing any data. A connectionless service can send the data without any need to establish a connection first. In general, connection-oriented services provide some level of delivery guarantee, whereas connectionless services do not. Connection-oriented service involves three phases: connection establishment, data transfer, and connection termination. During connection establishment, the end nodes may reserve resources for the connection. The end nodes also may negotiate and establish certain criteria for the transfer, such as a window size used in TCP connections. This resource reservation is one of the things exploited in some denial of service (DOS) attacks. An attacking system will send many requests for establishing a connection but then will never complete the connection. The attacked computer is then left with resources allocated for many never-completed connections. Then, when an end node tries to complete an actual connection, there are not enough resources for the valid connection. The data transfer phase occurs when the actual data is transmitted over the connection. During data transfer, most connection-oriented services will monitor for lost packets and handle resending them. The protocol is generally also responsible for putting the packets in the right sequence before passing the data up the protocol stack. When the transfer of data is complete, the end nodes terminate the connection and release resources reserved for the connection. Connection-oriented network services have more overhead than connectionless ones. Connection-oriented services must negotiate a connection, transfer data, and tear down the connection, whereas a connectionless transfer can simply send the data without the added overhead of creating and tearing down a connection. Each has its place in internetworks.
