What are the two main types of software?

• Firmware and middleware software

• Web software and database software

• Operating system and utility software

• System software and application software

Define application software and give an example.

• Application software is used for hardware management; an example is BIOS.

• Application software is only for mobile devices; an example is Instagram.

• Application software is software designed for end-users; an example is Microsoft Word.

• Application software is the same as system software; an example is Windows.

What is system software and how does it differ from application software?

• System software manages hardware and provides a platform for applications, while application software performs specific user tasks.

• System software is only for gaming applications.

• Application software manages hardware and system resources.

• System software is designed for web browsing and email.

Explain the role of a compiler in programming.

• A compiler is used to debug code and find errors.

• The role of a compiler in programming is to convert high-level code into machine code for execution.

• A compiler interprets code line by line during execution.

• A compiler manages memory allocation for programs.

What is the function of an interpreter?

• An interpreter is used to optimize code for better performance.

• An interpreter runs only low-level code without translation.

• The function of an interpreter is to execute high-level code by translating it into machine code line by line.

• An interpreter compiles high-level code into binary files.

Describe the differences between low-level and high-level languages.

• Low-level languages offer minimal abstraction and direct hardware control, while high-level languages provide greater abstraction and ease of use.

• Low-level languages are primarily used for web development.

• High-level languages require more memory than low-level languages.

• Low-level languages are easier to learn than high-level languages.

What are the generations of programming languages?

• 1GL, 2GL, 3GL, 4GL, 5GL

• 1GL, 2GL, 3GL, 6GL

• 1GL, 2GL, 3GL, 4GL, 7GL

• 1GL, 2GL, 3GL, 4GL, 8GL

What is primary memory and what are its characteristics?

• Primary memory is a type of non-volatile memory used for permanent data storage.

• Primary memory is characterized by low speed and indirect CPU access.

• Primary memory has unlimited capacity and is used for long-term data storage.

• Primary memory is a type of volatile memory used for temporary data storage, characterized by high speed, direct CPU access, and limited capacity.

Define secondary memory and provide examples.

• Examples of secondary memory include RAM and cache memory.

• Secondary memory is non-volatile storage used for long-term data retention. Examples include hard drives, SSDs, CDs, DVDs, and USB flash drives.

• Secondary memory is volatile storage that loses data when powered off.

• Secondary memory is temporary storage used for short-term data processing.

What are the different types of storage media?

• Paper, Diskette, Floppy

• RAM, ROM, Cache

• Magnetic, Optical, Solid-State, Flash, Cloud, Tape

• DVD, USB, Hard Drive
