What is binary?

A system of numerical notation that has 2 rather than 10 as a base.

What is the difference between RAM and ROM?

RAM is volatile memory that loses its contents once power is removed, while ROM is non-volatile memory that retains its contents even without power.

What is a firewall?

A network security system that monitors and controls incoming and outgoing network traffic.

What is an algorithm?

A set of rules to be followed in calculations or other problem-solving operations.

What is a compiler?

A program that translates source code written in a high-level programming language into machine code.

What is a loop?

A programming structure that repeats a sequence of instructions until a specific condition is met.

What is a data structure?

A particular way of organizing and storing data in a computer so that it can be accessed and modified efficiently.

What is a function?

A named section of a program that performs a specific task.

What is polymorphism?

The ability of an object to take on many forms.

What is encapsulation?

The technique of making the fields in a class private and providing access to the fields via public methods.

What is inheritance?

A mechanism in which one class acquires the properties and behaviors of another class.

What is abstraction?

The process of hiding implementation details while showing only the necessary information to the user.

What is a database?

A structured set of data held in a computer, especially one that is accessible in various ways.

What is a network?

A collection of computers and devices connected together, often wirelessly, and able to communicate with one another.

What is a operating system?

The most important type of system software in a computer system, which manages all its other programs and hardware.
