System Software MCQ-5

A grammar is considered ambiguous if it can generate more than one distinct parse tree or derivation for at least one string in its language.

Compilers are classified as system software because they serve as a bridge between the user's high-level source code and the machine-level instructions required for the computer to operate.

A macro processor is a part of the language translation process that expands macro definitions into full source code before the actual compilation or assembly begins.

EULA stands for End-User License Agreement. it is a legal contract between the software developer and the user that establishes the user's right to use the software.

EULA stands for End-User License Agreement, which outlines the terms, conditions, and restrictions of the software usage.

While Emacs is widely known as a text editor, in some academic contexts, it is distinguished by its extreme extensibility and environment-like capabilities compared to standard editors like Vi or Notepad.

Loaders handle low-level machine code or object code generated by the assembler or compiler and place it into the computer's memory for execution.

The Data Bus is bidirectional because the CPU needs to both send data to memory/peripherals and receive data from them.

In a two-pass assembler, the first pass is used to build the symbol table, and the second pass uses that table to generate the actual object code.

The standard phases of a compiler include Lexical, Syntax, and Semantic analysis, along with Intermediate code generation, Optimization, and Code generation. Static analysis is a separate tool process.

Real-time operating systems (RTOS) require strict synchronization and timing to ensure that tasks are completed within a specific, predictable time frame.

System programs are designed to manage and control the hardware components and overall system performance of the computer.

A Linker is a system program that combines multiple object modules produced by a compiler into a single executable binary program.

Shell sort is a sorting method often utilized within system programs like assemblers to organize symbol tables or other internal data structures.

While LL parsing is the standard top-down method, parsing techniques are generally categorized into top-down and bottom-up approaches to analyze the structure of a string based on a grammar.
