A computer program uses instructions written in a programming language to direct a computer's actions. Programming languages include symbols and codes that allow programmers to communicate with computers. There are hundreds of programming languages with different rules, and languages are often designed for specific purposes like business or web development. Programming languages can be categorized as either high-level or low-level based on whether they are machine-independent or machine-dependent.
2. A computer program is a series of instruction that directs a computer what to do
and how to do it
A compute programmer is a person who writes and modifies computer programs
to write program's instruction; programmers often use programming language
A programming langauge is a set of words , symbols, and codes that enables
aprogrammer to communicate instructions to a computer
Several hundred programming languages exist today. Each langauge has its own
rules for writing the instructions. Languages are often designed for specific
purposes, such as scientific applications, business sob or web development
They are two types of computer programming languages

3. Types of programming language
• High level programing language
• Low level language

4. High level programming langauge
• High-level langauge is a programming langauge that is machine
independent which means it can run on many different types of
computers and operating systems
• With high level langauge, each langauge instruction typically equates
multiple machine instructions

5. Low level langauge
• A low-level langauge is a programming langauge that is machine
dependent. A machine dependent runs on only one particular type
computer. These programs are not easily portable to other types
computers each langauge usually equates to single machine instruct
