Both hardware and software are necessary for working of a computer. It is anticipated that this book will minimize the amount of time for teachers in lesson preparation and more time will be devoted to actual classroom teaching and learning. What is the importance of computer system architecture? If a system is already running but needs to be restarted, it is called rebooting. Starting a computer or a computer-embedded device is called booting. Computer input is called data and the output obtained after processing it, based on users instructions is called information. controller until it finds the operation is completed, One or more special control lines to the CPU, Also known as an interrupt routine or device driver (generally part of the OS), Saved registers of a program before control is transferred to the interrupt Week 3. memory, A number of wires indicate the address of data to be accessed, Bus width determines maximum memory capacity of system (the number of memory E6UzQ 7=+WFy "6(4ga)x*U);-%lE]rBK^I>iZjyi(*XB"XHsOT).(p-vW+1x;~da7#Ug#;sPfEvfA&aV$!~lW[aRqC*g9/1!aQ2J9B;T n Translation of virtual addresses to physical or real addresses, 3.3.4.
