Is the interface, and manages software and hardware resources
Main functions: processing and, memory, files, equipment
Electronic devices: electricity-crystal-integrated
single-channel batch processing system
using magnetic storage equipment, internal and external storage operation speed increases
Throughput: single-hour workload
characteristics: automatic, sequential , One way from outside to inside
The correctness depends on the logical result of the system calculation, and also depends on the time to produce the correct result.
Used in industrial automatic control, intelligent robots, seabed exploration, and aerospace.
Features: The score is multi-reliability.
Basic operating system types: batch processing, time-sharing, real-time
host operating system
Three types of services: batch processing, 15 processing, time-sharing processing
OS/369 and OS/390
operating system characteristics: concurrency, sharing, virtual, asynchronous
Multi-channel batch processing system (without interactive function)
OS/360 is the first multi-program system developed by IBM.
