Program Consists of instructions executing one at a time. Input A program gets data, perhaps from a file, keyboard, touchscreen, network, etc. Brainpower 0:02 / 0:15 Process A programs performs computations on that data, such as adding two values like x + y. Output A programs puts that data somewhere, such as to a file, screen, network, etc. Computational thinking Creating a sequence of instructions to solve a problem.

Relational operators definition - Correct Answer-Relational operators are used for comparing the values. It either returns True or False according to the condition. These operators are also known as Comparison Operators. Relational operators examples - Correct Answer-> < == != >= <= What is the IL? - 1.1.1.4 Programming - absolute basics - Correct Answer-The IL is, in fact, the alphabet of a machine language. This is the simplest and most primary set of symbols we can use t...
