Glossary







            ✥   Address Bus: It is used to transfer addresses of memory locations for the CPU to perform read/write operations in the memory.
            ✥   Alternate Keys: A candidate key that is not chosen as the primary key is called an alternate key.

            ✥   Analytical Engine: The analytical engine is a mechanical computer capable of solving any mathematical problem.
            ✥   Application software: Application software is designed keeping in mind the requirements of its end-users.
            ✥   Arithmetic Logic Unit  (ALU):  The Arithmetic Logic  Unit (ALU) of the CPU  performs all  arithmetic ( +,-,*,/)  and  logical
               (>,<,>=,<=,<>) operations.
            ✥   Artificial intelligence: Artificial intelligence (AI) is a branch of computer science that aims to make machines so intelligent that
               they can perform tasks that typically require human intelligence, such as learning, reasoning, problem-solving, perception,
               and natural language understanding.

            ✥   Attribute: An attribute defines the characteristics of an entity.
            ✥   Augmented reality: Augmented reality overlays digital information onto the real world, creating a hybrid experience that
               blends the physical and digital worlds.

            ✥   BETWEEN operator: The BETWEEN operator checks whether a value is within a specified range (inclusive of both lower limit
               and upper limit values).

            ✥   Big data: Big data refers to extremely large and complex datasets that cannot be easily managed, processed, and analyzed
               using traditional data processing tools and techniques.

            ✥   Blockchain technology: Blockchain technology is a decentralized, distributed ledger that records transactions on multiple
               computers, providing a secure and transparent way to store and transfer data.

            ✥   break Statement: break statement terminates the same loop in which it is defined and moves the control to the next
               statement immediately following the loop.

            ✥   Cache Memory: The cache is used to store the frequently used instructions and data.
            ✥   Candidate Key: A set of attributes that uniquely identify each tuple in a relation is called its candidate key.
            ✥   Cardinality: The number of rows in the entity set of a relation defines the cardinality of the relation.

            ✥   Cloud computing: Cloud computing is a technology that allows users to access computing resources and services over the
               Internet, without having to purchase them at their workplace.

            ✥   Constraint: A constraint specifies the restrictions imposed on the data stored.
            ✥   continue Statement: The continue statement is also a jump statement, just like the break statement. When a continue
               statement is encountered, the remaining statement(s) in the loop is skipped and the control jumps to the beginning of the
               loop for the next iteration.

            ✥   Control Bus: It is used to transfer control signals between various computer components.
            ✥   Control Unit (CU): The Control Unit (CU) controls the execution of instructions and the flow of data amongst the components
               of a computer.

            ✥   CPU: The Central Processing Unit (CPU), also called the process or, is the computer’s brain and is responsible for carrying out
               all the processing in the computer system.

            ✥   Data Bus: It is used to transfer data between different CPU components.
            ✥   Data Definition Language (DDL): Data Definition Language (DDL) is used for describing database structure.
            ✥   Data Manipulation Language (DML): DML is used to retrieve and modify data.
