Study Notes
Classification of Software
- Application software: programs that complete a specific task for the user, e.g., word processors, web browsers, and spreadsheet software
- System software: operates, controls, and maintains the computer and its components
- System software includes: • Operating system • Utility programs • Library programs • Translators
System Software
- Operating system: • allows user to control the computer with ease by providing a virtual machine • manages and controls access to the computer's resources • tasks include memory management, processor scheduling, and handling interrupts
Utility Programs
- Used for completing housekeeping tasks in a computer system, e.g., data backup, defragmenting hard drives, data compression, and encryption
Library Programs
- Contain useful functions frequently used by a program
- Programmers can use libraries to simplify the programming process
- Libraries must be imported within the program code
Translators
- Translate between different types of language
- Types of translators: compilers, assemblers, and interpreters
Relationship between Hardware and Software
- Hardware: physical components of the computer system, e.g., hard drive, sound card, printers, and speakers
- Software: program code, sequences of instructions executed to perform a task
Role of an Operating System
- Hides the complexities of the hardware
- Handles resource management, allocating processors, memories, and I/O devices among competing processes
