Study Notes
Operating System (OS) Services
- The Operating System (OS) masks the details of the hardware from the programmer.
- The OS provides services for controlled access to files in the file management area.
- The OS provides a convenient interface for using the computer hardware and software structure.
System Program
- The term "system program" refers to the program that provides services for error detection and response.
- The most important function of the OS is to provide a convenient interface for using the computer hardware and software structure.
Application Programming Interface (API)
- The API provides a set of libraries and tools for a program to use.
Interface
- The system call interface defines the interface to the OS and the hardware resources and services available in a system through the user ISA.
- The primary responsibility of the OS as a resource manager is to manage the allocation and deallocation of system resources.
System Interaction
- In the early days, programmers interacted with the computer hardware directly.
- A batch system involves batching user programs together and submitting them for execution by a computer operator.
- A time-sharing system allows users/programmers to interact with the computer during the execution of a job.
Portability
- The use of standard APIs enabled application software to be ported easily to other systems that support the same standard.
Instruction Set
- The term "Instruction Set" refers to the collection of different instructions that the processor can execute.
- The operation code (opcode) specifies the operation to be performed in a machine instruction.
- The source operand reference specifies the location of the data to be used in a machine instruction.
- The result operand reference specifies the location where the result of the operation will be stored.
- The next instruction reference indicates the location of the next instruction to be executed.
- The binary code specifying the operation to be performed is known as the opcode.
- The operand address calculation is used to calculate the address of the operand in the instruction cycle.
- The representation of opcodes by abbreviations (mnemonics) allows programmers to write instructions more easily.
- Arithmetic instructions perform arithmetic operations such as addition and subtraction.
- The immediate area contains the data to be used in the instruction.
- Test instructions are used to test conditions and make decisions.
- Operand fetch involves retrieving the operands (data) needed for the instruction.
- Logic (Boolean) instructions operate on binary values (true or false).
- The OS is not responsible for managing the allocation of the keyboard.
