The document discusses different types of computer software. System software includes the operating system, which manages hardware resources and provides services to users. It acts as an interface between hardware and application programs. A translator converts programs between languages, with compilers translating the entire program to machine code at once and interpreters translating line by line. Utility software performs specific tasks like disk maintenance, antivirus scanning, and file compression to optimize system performance.

8. Program
Translator
A translator is a
programming language
processor that converts a
computer program from
one language to another.
It takes a program
written in source code
and converts it into
machine code.

13. Advantages of utility software
• It performs a specific and useful function to maintain and
increase the efficiency of a computer system
• Aids in keeping the computer free from unwanted software
threats such as viruses or spyware
• Adds functionality that allows the user to customize your desktop
and user interface
• Manages computer memory and enhances performance

14. Activity: True or False
• Software is classified into two categories.
• System software supports the execution of other application
software.
• An interpreter translates the whole program at a time.
• A compiler translates one instruction at a time.
• Every computer needs operating system software.

15. Draw lines
to match
