System Software

What is the primary function of an operating system (OS)?

• Manage computer hardware resources

• Run application software

• A&B

• None

What does utility software primarily focus on?

• Running applications efficiently

• Performing specific tasks like disk cleanup and antivirus scanning

• Managing hardware resources

• Developing software programs

Explain the role of a dynamic link library (DLL) in software development

• A) It compiles source code into machine code

• B) It provides reusable code that can be loaded at runtime

• C) It manages device drivers

• D) It encrypts data for security purposes

What are the key differences between interpreters and compilers?

• • A) Interpreters translate code line by line, while compilers translate the entire code at once

• • B) Compilers are faster than interpreters

• • C) Interpreters generate machine code directly

• • D) None of the above

Describe the process of defragmentation and its benefits.

• • A) It organizes fragmented data on a disk to improve performance by reducing data access time

• • B) It compresses files to save disk space

• • C) It encrypts data for security purposes

• • D) It creates duplicate copies of files for backup

Discuss the advantages and disadvantages of using an interpreter versus a compiler in software development.

• A) Interpreters allow for real-time error detection but may run slower; compilers produce faster executables but require more time for initial development

• B) Compilers are easier to use than interpreters but require the source code to be distributed

• C) Interpreters are more secure than compilers but execute programs slower

• D) None
