What is an Operating System?

A program that acts as an intermediary between a user of a computer and the computer hardware.

Operating system goals:

Execute user programs and make solving user problems easier.

Make the computer system convenient to use.

Use the computer hardware in an efficient manner.

Computer Startup

bootstrap program is loaded at power-up or reboot

Typically stored in ROM or EEPROM, generally known as firmware

Initializates all aspects of system

Loads operating system kernel and starts execution

Common Functions of Interrupts

A trap is a software-generated interrupt caused either by an error or a user request.

I/O Structure

System call – request to the operating system to allow user to wait for I/O completion.

Caching

Important principle, performed at many levels in a computer (in hardware, operating system, software)

Information in use copied from slower to faster storage temporarily

Faster storage (cache) checked first to determine if information is there

If it is, information used directly from the cache (fast)

If not, data copied to cache and used there

Cache smaller than storage being cached

Cache management important design problem

Cache size and replacement policy

請不要用翻譯軟體或是翻譯網頁翻譯 謝謝

Update:

Schedulers (Cont.)

Short-term scheduler is invoked very frequently (milliseconds) Þ (must be fast)

Long-term scheduler is invoked very infrequently (seconds, minutes) Þ (may be slow)

The long-term scheduler controls the degree of multiprogramming
