A computer program consists of a chronological series of instructions, referred to as code,
authored in a specific computer language to direct a machine toward a particular task.
Common applications of this include operating systems, browsers, utility tools, media players,
I
and spreadsheet apps.
ER
It is crucial to understand that these instructions are executed in a fixed sequence unless the
code explicitly dictates a jump or change in flow.
A computer language is defined by a system of grammatical standards used to control a
device's behavior. This term is often used interchangeably with "programming languages."

The Concept of Programming
Programming is the blend of technical skill and creative logic used to command computers via
O
specialized languages.
It involves generating the code that instructs a machine on how to resolve issues and execute
various functions.
TY
By utilizing these languages, developers can build software, create websites, process complex
data, and automate repetitive tasks.
Historical Evolution of Programming
R
In its earliest stages, programming required writing machine code, which utilizes binary (0s and
1s) to interact directly with hardware. As computing evolved, high-level languages emerged to
PE
streamline development.
These modern languages allow creators to use syntax that closely resembles human language,
making the process much more intuitive.
Programming Paradigms
O
A "paradigm" acts as a pattern or a specific methodology for organizing code.
PR
These serve as conceptual blueprints for architecting software and solving logical problems.
Major paradigms include:
● Procedural Programming: Also known as imperative programming, this style organizes
code into reusable functions and emphasizes a step-by-step execution path. Examples:
BASIC, C, Pascal, and Java.
