Computers require programs written in binary language, not English, to perform tasks efficiently. The C programming language, developed by Dennis Ritchie, is crucial for system programming due to its power and versatility.
Insights
- Programs written for computers need to be converted into machine language, consisting of binary code (0s and 1s), for the computer to understand and execute them effectively.
- The development of high-level programming languages like C, C++, and Java has significantly enhanced the accessibility and readability of programming, allowing individuals to create custom software solutions for various tasks efficiently.

"Computer Programming: From Instructions to Execution"
- Computer is a general-purpose machine that can perform computational tasks, but communication with it requires writing programs, which are sequences of instructions given to the computer.
- Computers understand only binary language (0 and 1), so writing instructions in English or any other language is not comprehensible to them; programs need to be converted into machine language for execution.
- Programs are essential for computers to perform tasks, and they are written in programming languages like C, which need to be converted into machine language using compilers for the computer to execute them.
- System programs manage system resources and hardware, while application programs are used for specific tasks like web browsing or text editing; writing your own program is necessary for custom tasks.
- High-level programming languages like C, C++, and Java are more human-readable compared to machine-level languages, making programming more accessible and understandable.
- C language, developed by Dennis Ritchie in 1972 at Bell Laboratories, is a powerful system programming language used for various software development, including operating systems like Unix, Android core libraries, and device drivers.
- Programs written in C need to be converted into machine code using compilers before execution, making C a compiled language; the process of program execution involves compilers, linkers, loaders, and interpreters, each with specific roles.
