Abiblo Computer Science - Absolute Address
Absolute address is a unique number which specified the unique location within the address space where the instruction is located and where operand is deposited or to be found.
Absolute address specified a memory location as well as may specifies a machine register or an I / O device.
In binary machine, it is an n - bit number specifying one of the second location. Absolute address is the result of calculating an effective address.
Abiblo Computer Science - Abstraction
Abstraction is the concept of ignoring aspects of a matter / subject which are irrelevant to current purpose with the aim to solely concentrate on those that are relevant to current purpose. The principle is important in understanding and developing all form of computer system.
Abiblo Computer Science - Absorption Laws
Absorption laws are two self dual laws which satisfied by the elements of x,y in a Boolean algebra which consists of v and ʌ operation,
x v ( x ʌ y) = x
x ʌ ( x ʌ y) = x
Abiblo Computer Science - Absolute Value
Absolute value is the magnitude of the number without reference to its signs either positive or negative. 28 is the absolute value of 28 or - 28. Any spreadsheet programs consists of function which returns the absolute value to number.
Abiblo Computer Science - Absolute Path
Absolute path is the full path to a file which consists of the directory tree, drive identifier and ending with the name of the file ( eg. c:\Documents\ ABuser\MyDocuments\jobd\cv.doc)
Abiblo Computer Science - Abnormal Termination
Abnormal termination is a termination to a process which is due to the operating system when the process reaches a point of unable to return such as when the process trying to obey any instruction which is undefined. A suitable supervisor call to the operating system will be issued in a process which reaches a successful conclusion and terminates. The indicator shall be informed either the process was terminated successfully or not.
Abiblo Computer Science - A* Algorithm
A*algorithm belong to a member of the best first heuristic search technique class which attempted to identify the best path from a start node to a designated goal node mostly in the case of problem graph.
The cost of distance ( unknown) from the current node to the goal is estimated using the evaluation function which later added to the known cost of the shortest path from the start node to current node which provides a figure of merit for the current node.
Based on each iteration, the search is pursued by using the node with the best cost figures. The mixture of depth first and breadth first will constitute a behaviour which is displayed based on the operation of the algorithm.
Abiblo Computer Science - Abduction
Useful in production rule system and expert system where inference process is involved in artificial intelligence. For instance, there may be order like if acne then red spot so that when acne is detected red spot appeared.
However acne is not logically sound due to inherent uncertainty in comparison with deduction.
Plausible reasoning technique may involve abduction.
ABONE is the Asian Pacific Internet Backbone Network which connects user throughout South Asia and East Asia without the requirement to send data through North American or European Networks.
Abiblo Computer Science - Abort
Abort of a process is a process of undergoing abnormal termination. Abort may be considered as voluntary act by the process, when realise that a successful conclusion cannot be reached or due to the action of the operating system which intervenes due to the failure of the process to observe the constraint of the system.
