Computer System

Structure

 Computer system can be divided into four

components

 Hardware – provides basic computing resources

 (^) CPU, memory, I/O devices

 Operating system

 (^) Controls and coordinates use of hardware among various applications and users

 Application programs – define the ways in which the
system resources are used to solve the computing
problems of the users

 (^) Word processors, compilers, web browsers, database systems, video games

 Users

 (^) People, machines, other computers

Four Components of a Computer

System

What does industry mean when it says “Operating System”

 No universally accepted definition

 One view: “Everything a vendor ships when

you order an operating system”, but that

varies wildly

 Another view: “The one program running at all

times on the computer” (i.e., the kernel)

 Everything else is either a system program (ships
with the operating system) or an application
program

Four Major Management Functions of an Operating System

 (^) Process Management

 (^) Memory Management

 (^) Storage Management

 (^) Protection and Security
