1 data-link layer
"Layer two of the OSI model. A layer that packages raw bits from the physical layer into frames (logical, structured packets for data). This layer is responsible for transferring frames from one computer to another, without errors. After sending a frame, the data-link layer waits for an acknowledgment from the receiving computer." -
2 data tier
"A layer that is part of a three-tier server software architecture that stores and persists data. Each logical server machine group contains an interface tier (a perimeter network), an application tier, and a data tier. This architecture provides high levels of scalability." -
3 network layer
"Layer three of the OSI model. A layer that addresses messages and translates logical addresses and names into physical addresses. It also determines the route from the source to the destination computer and manages traffic problems, such as switching, routing, and controlling the congestion of data packets." -
4 Secure Sockets Layer
"The protocol that improves the security of data communication by using a combination of data encryption, digital certificates, and public key cryptography. SSL enables authentication and increases data integrity and privacy over networks. SSL does not provide authorization or nonrepudiation." -
5 ATM adaptation layer
The layer of the asynchronous transfer mode (ATM) protocol stack that parses data into the payload portion of the ATM cell for transport across an ATM network.طبقة ملاءَمة ATM -
6 bridge
"Software or hardware that connects two or more networks so that they can communicate, and that operates at the data-link layer (layer 2) of the OSI model." -
7 HDLC
"A protocol for information transfer adopted by the ISO. HDLC is a bit-oriented, synchronous protocol that applies to the data-link (message-packaging) layer (layer 2 of the ISO/OSI reference model) for computer-to-microcomputer communications." -
8 network bridge
"Software or hardware that connects two or more networks so that they can communicate, and that operates at the data-link layer (layer 2) of the OSI model." -
9 packet
"An Open Systems Interconnection (OSI) network layer transmission unit that consists of binary information representing both data and a header containing an identification number, source and destination addresses, and error-control data." -
10 Link Control Protocol
A PPP control protocol that negotiates link and PPP parameters to dynamically configure the data-link layer of a PPP connection. -
11 LCP
A PPP control protocol that negotiates link and PPP parameters to dynamically configure the data-link layer of a PPP connection. -
12 AAL
The layer of the asynchronous transfer mode (ATM) protocol stack that parses data into the payload portion of the ATM cell for transport across an ATM network. -
13 logical link control and adaptation protocol
"A protocol used in personal wireless network applications that provides connection-oriented and connectionless data services to upper layer protocols with protocol multiplexing capability, segmentation and reassembly operation, and group abstractions."English-Arabic terms dictionary > logical link control and adaptation protocol
-
14 L2CAP
"A protocol used in personal wireless network applications that provides connection-oriented and connectionless data services to upper layer protocols with protocol multiplexing capability, segmentation and reassembly operation, and group abstractions." -
15 sparing table
A remapping table in the UDF file format that allows defect management with disk/drive systems that do not typically perform defect management (e.g. CD-RW) by reallocating the data at the file system layer when a defective block is encountered. -
16 storage tier
An optional layer of a storage space that writes data to physical disks of a particular speed.
