Study Notes
System Support Programs
- Support the operations, management, and users of a computer system
- Perform common tasks: sorting records, checking disk integrity, creating directories and subdirectories, restoring accidentally erased files, locating stored files, managing memory usage, and redirecting output
Defragmenting
- Process of rearranging the data on a storage medium, such as a hard disk drive (HDD), for efficient storage and access
- Improves a computer's or laptop's performance and speed
Computer Software Systems
- Systems Software: makes the computer function, manages hardware resources
- Application Software: performs specific user tasks, does something interesting
Systems Software
- Controls and supports the computer system's activities
- Supports application software by directing the computer's basic functions
- Facilitates program development, testing, and debugging
- Is independent of any specific type of application
System Control Programs
- Control use of all system resources (hardware, software, data)
- Operating System: main system control program, supervises the overall operation of the computer, allocates CPU time and main memory to programs running on the computer, provides an interface between the user and the hardware
Types of Operating Systems
- Major Desktop Operating Systems: Microsoft Products (MS-DOS, Windows 95, Windows 98, Windows NT, Windows 2000, Windows ME, Windows XP), UNIX, Linux, Macintosh Operating System (MacOS)
- Departmental Server Operating Systems: support hundreds of concurrent users, examples include UNIX, Linux, Windows 2000, Windows XP, Novell NetWare, MacOS
- Enterprise Operating Systems: support thousands of concurrent users, millions of transactions per day, examples include IBM's OS/390, IBM's VM (Virtual Machine), IBM's VSE (Virtual Storage Extended), and IBM's OS/400
