1 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." -
2 Data Link Control
"An error-correction protocol in the Systems Network Architecture (SNA) responsible for transmission of data between two nodes over a physical link. Supported by Microsoft Windows NT and Windows 2000, DLC is designed to provide access to IBM mainframe computers and to Hewlett-Packard printers connected to the network." -
3 Distributed Relational Database Architecture
"A connection protocol for distributed relational database processing used by IBM relational database products that comprises protocols for communication between an application and a remote database, and communication between databases. DRDA also provides the connections for remote and distributed processing. The Distributed Data Management Architecture provides the base architecture for DRDA."English-Arabic terms dictionary > Distributed Relational Database Architecture

4 64 bit machine
"A computer that works with data in groups of 64 bits at a time. A computer may be considered a 64-bit machine either because its CPU operates internally on 64-bit words or because its data bus can transfer 64 bits at a time. A 64-bit CPU thus has a word size of 64 bits, or 8 bytes; a 64-bit data bus has 64 data lines, so it ferries information through the system in sets of 64 bits at a time. Examples of 64-bit architecture include the Alpha AXP from Digital Equipment Corporation, the Ultra workstation from Sun Microsystems, Inc., and the PowerPC 620 from Motorola and IBM." -
5 SDLC
A type of link service used for managing synchronous data transfer over standard telephone lines (switched lines) or leased lines. The data transmission protocol most widely used by networks conforming to IBM's Systems Network Architecture (SNA). SDLC is similar to the HDLC (High-level Data Link Control) protocol developed by the International Organization for Standardization (ISO). -
6 OLE DB provider
"A program in the OLE DB architecture that enables native access to data, instead of accessing data using ODBC or IISAM drivers, which are external ways to access the data." -
7 DRDA
"A connection protocol for distributed relational database processing used by IBM relational database products that comprises protocols for communication between an application and a remote database, and communication between databases. DRDA also provides the connections for remote and distributed processing. The Distributed Data Management Architecture provides the base architecture for DRDA." -
8 OLE DB
"A component database architecture that provides efficient network and Internet access to many types of data sources, including relational data, mail files, flat files, and spreadsheets." -
9 PowerPC
"A microprocessor architecture developed in 1992 by Motorola and IBM, with some participation by Apple. A PowerPC microprocessor is RISC-based and superscalar, with a 64-bit data bus and 32-bit address bus. It also has separate data and instruction caches, although the size of each varies by implementation. All PowerPC microprocessors have multiple integer and floating-point units. The voltage and operating speed varies with the implementation. Starting with the PowerPC 740, the microprocessors were manufactured with copper, instead of aluminum, for better performance and reliability." -
10 DLC
"An error-correction protocol in the Systems Network Architecture (SNA) responsible for transmission of data between two nodes over a physical link. Supported by Microsoft Windows NT and Windows 2000, DLC is designed to provide access to IBM mainframe computers and to Hewlett-Packard printers connected to the network." -
11 byte order
"The processor memory architecture in which bytes of data (typically, integer values) are stored. The two most common orders are: little endian (least significant byte is placed first) and big endian (most significant byte is placed first)." -
12 .NET Compact Framework
"A hardware-independent environment for running programs on resource-constrained computing devices. It inherits the full.NET Framework architecture of the common language runtime, supports a subset of the.NET Framework class library, and contains classes designed exclusively for the.NET Compact Framework. Supported devices include personal data assistants (PDAs) (such as the Pocket PC), mobile phones, set-top boxes, automotive computing devices, and custom-designed embedded devices built with the Microsoft Windows CE.NET operating system."إطار العمل المضغوط لـ.NET -
13 Cloud App Model
"An application-hosting architecture that relies on cloud-based services. Application logic and data are typically hosted on a distributed set of services on the Internet, connected through web APIs, and authenticated with server-to-server authentication technologies such as OAuth."
