EXAMPLE OPERATION
Click mouse on internet explorer icon – message makes way to CPU
ECEn 191 – New Student Seminar - Session 8: Computer Systems
ECEn 191 – New Student Seminar – Session 7: Computer Systems
EXAMPLE OPERATIONCPU runs a program called “interrupt handler” to figure out what mouse wants
CPU sends message to disc drive requesting file representing Explorer
