CS492 Complete Midterm Review Processes: ● Process - a program in execution ● A single CPU at any given time may only run one process ● CPU Utilization: 1 - p​n ● Processes don’t shar e memory address space Syscalls: Calling a kernel mode service from user mod program ● switches execution to kernel mode ● Programming interface to services provided by the OS ● Typically written in a high-level language ● APIs: ○ Win32 API (Windows) ○ POSIX API (POSIX-based systems: UNIX, L...

These are notes that summarise and combine all the provided lecture slides as well as the additional textbook reading content with important diagrams and visual aids. The OS1 is the 3rd part of the syllabus to be covered and has all the important concepts, algorithms and application examples that you need to ace test 2 and the exam! :)

UF COP4600 - Exam 1 Algorithm - ANS set of instructions with finite initial store and state, a starting point, and unambiguous ordering until the endpoint Process (general definition) - ANS a program in execution = program + state Program - ANS sequence of instructions that embody an algorithm Job - ANS a task to be completed Why need an O.S.? - ANS - load program onto computer - access and supervise I/O devices - manage resources - protect private info - ...

COP4600 Final Combined What pieces of hardware are in the CPU? - ANS Registers, ALU, and control unit Hardware which serves as the CPUs memory. There are special and general purposed of these - ANS Registers Hardware which does arithmetic and logical computations - ANS ALU Hardware which tracks state/status. Also controls other components - ANS Control unit Instruction cycle responsible for loading the instruction - ANS Fetch Instruction cycle responsible for ...
