Computer Science Concepts

What is the definition of "Absolute Error"?

• The difference between the actual number and the nearest representable value.

• The difference between the actual number and the theoretical value.

• The difference between two estimates of the same number.

• The difference between the maximum and minimum values in a dataset.

What does "Abstract Data Type (ADT)" refer to?

• A data type whose properties are specified independently of any particular programming language.

• A data type that can only store abstract concepts.

• A data type specific to object-oriented programming.

• A data type defined with specific syntax and behavior in a given programming language.

What is "Abstraction" in computing?

• Representation that is arrived at by removing unnecessary details.

• A method of representing data in the form of a table.

• A system that encrypts data for security purposes.

• A way of storing data in multiple formats.

What does "Aggregation" mean in object-oriented programming?

• A type of association where the aggregated object has a weaker form of association with the objects that it is aggregating than is the case with composition.

• A relationship where one object fully owns another.

• A process of combining data from multiple sources into a single format.

• A method of grouping objects based on their attributes.

What is "Ajax" technology used for?

• Web technology that allows only the part of a web page that needs updating to be fetched from the web server.

• A method for encrypting web pages before they are sent.

What is an "Algorithm"?

• A sequence of unambiguous instructions for solving a problem.

• A list of possible solutions to a problem.

• A program that runs automatically without human interaction.

• A process for checking errors in a system.

What is an "Application Programming Interface (API)"?

• A layer of software that allows application programs to call on the services of the operating system.

• A tool for building and debugging code.

• A set of guidelines for writing efficient code.

• A method for encrypting application data.

What is "Association" in object-oriented programming?

• A relationship between two classes.

• A way of grouping classes based on their properties.

• A method for hiding implementation details of a class.

• A process of defining a class's attributes.

What does "Asymptotic Behaviour of f" describe?

• Behaviour of the function f(n) for very large values of n.

• Behaviour of the function f(n) for small values of n.

• The exact solution of a function over a specific range.

• The graph of a function when plotted in a limited range.

10. What is "Asynchronous Serial Data Transmission"?

• A method of data transmission where data is sent one bit at a time, with start and stop bits to signify the beginning and end of each byte.

• A method of data transmission where data is sent in parallel, with multiple bits sent simultaneously.

• A method of data transmission that requires a clock signal to synchronize the transmission of data.

• A method of data transmission that uses light to transmit data over long distances.
