Networking

2. A set of tools and procedures provided by the programmer of an application so that other programmers can control, exchange data with, or extend the functionality of an application.
5. n a network packet or frame, a section of data that describes the data that immediately follows.
6. A reliable Transport Layer Protocol for managing IP that supports re-transmission, sequencing and fragmentation.
7. Sequence of messages exchanged between two or more network devices to ensure transmission synchronization.
11. American National Standards Institute.
12. A set of rules and decision structures for actions in a specifically defined set of circumstances.
13. A non-encrypted process to access a remote computer system, often a Unix system, over the network.
14. The basic unit of data representation in digital computers.
15. A loss in the amplitude or strength of a signal due to an interaction with the signal's media. Generally expressed in decibels.
19. IEEE 802.3 interface between an MAU and a NIC (network interface card). Also called transceiver.
20. An unusual instance or circumstance.
21. An abrupt termination or computing activity caused by an error. Inmany instances, the computer becomes completely unusable and must be restarted before activity can resume.
23. UC Berkeley's distribution of the Unix operating system.

1. A TCP/IP router that routes packetsbetween different network numbers.
3. A group of 8 bits
4. The protocol for mapping IP addresses to physical addresses such as Ethernet or Token Ring.
8. Seven layer of the OSI reference model. This layer provides services to application processes (such as electronic mail, file transfer, and terminal emulation) that are outside of the OSI model.
9. An information transmission that is intended to be interpreted by all entities capable of receiving it.
10. Router or access server, or several routers or access servers, designated as a buffer between any connected public networks and a private network. It uses access lists and other methods to ensure the security of the private network.
11. Available bit rate. QOS class defined by the ATM Forum for ATM networks. Also used in OSPF to define a certain type of border router.
14. The standard TCP/IP naming service that links network names with IP addresses.
16. Classless interdomain routing. Technique supported by BGP4 and based on route aggregation.
17. A group of memory locations set aside for temporary storage ofdata, especially frequently-used data or data needing high speedretrieval
18. In Ethernet, the result of two nodes transmitting simultaneously. The frames from each device impact and are damaged when they meet on the physical media.
22. IBM's implementation of Unix.
