Glossary
✥ Address Bus: It is used to transfer addresses of memory locations for the CPU to perform read/write operations in the memory.
✥ Adware: An adware is a software that displays advertisements to users of the Internet and mobile applications.
✥ Algorithm: A sequence of steps to be followed in solving a problem.
✥ Apache: Apache is an open-source software project, an initiative by the Apache Software Foundation (ASF).
✥ Arithmetic Logic Unit (ALU): The Arithmetic Logic Unit (ALU) of the CPU performs all arithmetic (+,-,*,/) and logical
(>,<,>=,<=,<>) operations.
✥ Assembler: It converts the program written in assembly language to machine language.
✥ Assignment Operators: Assignment operators are used to assign the value of the operand on the right-hand side of the
operator to the operand on the left-hand side of the operator.
✥ Boot Sector Virus: A boot sector virus is a virus that affects the boot sector of the disks.
✥ break Statement: The 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 memory is a special high speed memory storing the most recently accessed data.
✥ Compiler: A compiler converts a program written in a high-level language to an equivalent program in the computer’s machine
language.
✥ Conditional expression: In case of conditional flow, the execution of the statements depends upon conditional expression.
✥ Conditional Statements: A conditional statement may also be referred as a decision-making statement or branching statement.
✥ continue 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.
✥ Copyright Infringement: The use or creation of copyright-protected works without the owner’s consent is copyright
infringement.
✥ Copyright: When an author or an organisation sets a work in a physical form of expression, they have a copyright on it that
prevents others from claiming its ownership.
✥ CPU: Central Processing Unit (CPU) is the computer’s brain and is responsible for carrying out all the processing in the
computer system.
✥ Cyber Bullying: When a victim is bullied online, on social media, or in gaming communities, that is known as cyberbullying.
✥ Cyber Forensics: Cyber forensics aims to use the IT infrastructure to track cybercrimes.
✥ Cyber Trolls: Trolls are comments or posts that insult or defame other users or their content.
✥ Cybercrime: Cybercrimes are crimes related to the misuse of resources available on the Internet.
✥ Cyberlaws: Cyberlaws are statutory provisions against various forms of cybercrime.
✥ Data Bus: It is used to transfer data between different components.
✥ Debugging: The process of identifying and removing such errors is known as debugging.
✥ Delimiters: Delimiters are symbols used to separate various tokens in a statement.
✥ Dictionary(Mapping): A dictionary (dict) is an unordered set of key-value pairs enclosed in curly brackets:{}.
✥ Dictionary in Python: A dictionary is an unordered set of key:value pairs.
✥ Digital Footprint: A digital footprint is a trail of personal data that one leaves behind while using the Internet.
