A set of rules which the networks arbitrate their use.
(verb) (1) To use. For example, programs can access memory, which means they read data from or write data to main memory. A user can access files, directories, computers, or peripheral devices. (2) More specifically, access often means to read data from or write data to a mass storage device. The time it takes to locate a single byte of information on a mass-storage device is called the access time. (3) To visit a Web site. (Noun) (1) The act of reading data from or writing data to a storage device. (2) A privilege to use computer information in some manner. For example, a user might be granted read access to a file, meaning that the user can read the file but cannot modify or delete it. Most operating systems have several different types of access privileges that can be granted or denied to specific users or groups of users.
the technique used to access data on a physical file device. Types of access methods include sequential, index sequential, hierarchical structure, network structure, relational structure, etc.
The method by which networked stations determine when they can transmit data on a shared transmission medium. Software within an SNA processor that controls the flow of information through a network.
The way in which the user interacts with a device to control it for communication; the method an individual uses to select items for communication, e.g. pointing, single-switch scanning, etc. There are two broad categories of access methods: 1) Direct selection and 2) Indirect Selection (Dowden & Cook, 2002).
1) The technique and/or the program code in a computer operating system that provides input/output services. The access method typically carries an implied data and/or file structure with logically similar devices sharing access methods. Examples are IBM's VTAM and TCAM. 2) In local area networks, the technique and/or program code used to arbitrate the use of the communications medium by granting access selectively to individual stations. Examples are CSMA-CD and token passing.
A protocol that determines which device in a local area network has access to the transmission media at any instant. CSMA/CD is an example of an accessmethod. IBM uses the same term for specific kin ... more
An access method is an executable used by extended agents to connect and control job execution on other operating systems (for example, MVS) and applications (for example, Oracle Applications, Peoplesoft, and R/3). The access method must be specified in the workstation definition for the extended agent.
the communications protocol that the SAS SQL Library for C uses to exchange data with a SAS server. The SAS SQL Library for C uses the TCP/IP access method.
A software mechanism for accessing data in a file system. Access methods can support sequential access, random access, and keyed access (for example, VSAM).
A set of server routines that the database server uses to access and manipulate an index or a table. B-tree is the default secondary access method used by DataBlade modules. Some DataBlade modules have their own access methods, with routines defined by the module. See also primary access method, secondary access method.
A software routine that is part of a network control program and controls access to the network.
A type of access control parameter that limits access to objects according to the methods clients use when making requests. Purveyor supports the following HTTP methods: GET HEAD POST * (any method)
the communications protocol that the SAS ODBC driver uses to exchange data with a SAS server. The driver currently supports the use of TCP/IP and Network DDE for remote data exchange, and DDE for local exchange.
A technique used to transfer a physical record from or to a storage device.
Technique for moving data between main storage and input/output devices. In a Systems Network Architecture (SNA) environment, it is the software that controls the flow of information in a network.
The technique used for selecting records in a file, one at a time, for processing, retrieval or storage. The access method is related to, but distinct from, the file organization that determines how the records are stored.
Method used to log on to a service, download records or reports, or locate additional information. For example, a URL (Uniform Resource Locator) is used to find information on the Internet.
method that encapsulates data members.
The technique or the program code in the operating system that provides input/output services. It defines where a group of data will be stored on a medium. By including the access method in the basic operating system, computer makers have made the programmer's job much easier.
Rules that govern how nodes on a network access the transmission media.
A set of rules by which network stations arbitrate their access to a shared-media LAN. Examples include ATM, Ethernet, token ring, and FDDI.
