Q

Bit

A

The smallest unit of data that can be stored by a computer; it is another name for binary digit, as it represents a logical value in the form of a numerical - ‘0’ or ‘1’

Q

Describe the representation of info in a system

A

All information in a system is represented in the form of bits. However, the context is a key factor in distinguishing between different data objects.

Q

Compiler driver/compilation system

A

Software that translates a source file to an object file. It is composed of four programs, namely preprocessor, compiler, assembler, and linker.

Q

Define the preprocessing phase of the compilation process/the function of the preprocessor program

A

The preprocessor (ccp) modifies the original source code/.c file by following directives that begin with the ‘#’ character (#include, #define for e.g.) and removing comments. This typically results in the C program being converted into a .i file

Q

Define the function of the #include <header file> directive

A

include instructs the preprocessor to read the contents of the given file into the source program/file/code.

Q

Define the compiling phase of the compilation process/the function of the compiler program

A

The compiler (cc1) parses the syntaxes of the preprocessed code (.i file) into an assembly language program/file; it converts the .i file into a .s file.

Q

Assembly code

A

A sequence of low-level machine language instructions written in textual form; an intermediary between textual code and machine/binary code; stored in a .s file/program.

Q

Define the assembly phase of the compilation process/the function of the assembler program

A

The assembler parses the assembly-language program (.s file) into a relocatable object program/file. It stores the resulting code into a .o file. The assembly code is converted into object code, i.e. low-level machine language instructions in binary form.

Q

Define the linking phase of the compilation process/the function of the linker program

A

The linker merges any precompiled object files resulting from any C library functions in the relocatable object file (.o) to generate an executable object file/executable that can be loaded into the computer memory and executed by the system.

17
Q

computer system/system

A

A collection of interlinked hardware and systems software that cooperate to run application software.

18
Q

hardware

A

The PHYSICAL parts of a computer that run software through the storage, movement, and transformation of data in the computer.
E.gs - Central Processing Unit (CPU), keyboard, Random Access Memory (RAM), motherboard, monitor, mouse
