Explanation

Java applets are small programs written in Java that run inside a web browser.

They are used for interactive features in web applications (though now largely outdated).

Explanation

A variable is a named memory location whose value can change during the execution of a program.

In contrast, a constant has a fixed value that does not change while the program runs.

Explanation

The UNIX operating system was originally developed in assembly, but later rewritten in C to make it portable.

This marked a major milestone in OS development, allowing UNIX to run on different hardware platforms.

Explanation

The C programming language was developed in 1972 by Dennis Ritchie

in the Bell Laboratories of the AT & T (American Telephone & Telegraph),located in U.S.A.

Dennis Ritchie is known as the founder of c language.

Co developer of Unix

C is a general-purpose computer programming language.

It was created in the 1970s.

By design, C's features cleanly reflect the capabilities of the targeted CPUs. 

Designed by: Dennis Ritchie

First appeared: 1972

Explanation

Assembly language is a low-level programming language that is just one step above machine language (binary code).

It uses mnemonics to represent machine instructions, making it easier for humans to read and write compared to raw machine code.

Explanation

The Data Link layer is responsible for physical addressing through MAC (Media Access Control) addresses.

The Physical layer deals with transmitting raw bits over the medium.

Explanation

A computer program is written using a set of codes (instructions) that the computer can understand.

These codes are composed of programming languages made up of symbols, words, and syntax, but collectively called codes.

Explanation

Semantic refers to the meaning of a statement in a programming language.

Syntax refers to the structure or rules of writing code.

The compiler translates code into machine language.

Explanation

Selection tools are used to select and crop or cut a part of an image or shape.

They help isolate specific areas for editing in graphic design or photo editing software.

Explanation

• Converter — not a standard module in C programming; there is no such step in the C compilation process

Additional information 

• Editor — used to write C code (source file)
• Linker — combines object files into an executable
• Compiler — converts C source code into object code (machine language)
