Answer 1

Answer:

1. BASIC UNIT OF MEMORY IS BYTE.

2. Beginners' All-purpose Symbolic Instruction Code

3. Language processor is also called a language translator.

4. (a) Source Code : In computing, source code is any collection of code, possibly with comments, written using a human-readable programming language, usually as plain text

(b) Object Code : In computing, object code or object module is the product of a compiler. In a general sense object code is a sequence of statements or instructions in a computer language, usually a machine code language or an intermediate language such as register transfer language

5. The features that a programming language must have to stand out are the following: Simplicity: the language must offer clear and simple concepts that facilitate its learning and application, in a way that is simple to understand and maintain

6. Utility software is software designed to help to analyze, configure, optimize or maintain a computer. It is used to support the computer infrastructure - in contrast to application software, which is aimed at directly performing tasks that benefit ordinary users.

7. Rules for naming variables:

• All variable names must begin with a letter of the alphabet or an. underscore( _ )
• After the first initial letter, variable names can also contain letters and numbers.
• Uppercase characters are distinct from lowercase characters.
• You cannot use a C++ keyword (reserved word) as a variable name.

8. The difference between constant and variable in C programming is that a constant is similar to a variable, but it cannot be modified by the program once it is defined while a variable is a memory location that holds data.
