Implementing Protection with Virtual Memory - computer architecture:
To enable the operating system to implement protection in the VM system, the HW have to:
I. Support at least 2 modes that denoted whether the running process is a user process (executive process) or an operating system process (kernel/supervisor process).
II. Provide a part ion of the CPU state that a user process may read but not write (includes supervisor mode bit).
o Only operating system process may change page tables. Page tables are held in operating system address space thereby preventing a user procedure from changing them.
o When processes desire to share information in a restricted way, the OS have to assist them.
o The write access bit (in both the TLB and the page table) can be used to limit the sharing to only read sharing.
Learning Weights in Perceptrons: Furthermore details are we will look at the learning method for weights in multi-layer networks next lecture. Thus the following description o
There is a pebble merchant. He sells the pebbles, that are used for shining the floor. His main duty is to take the length of the room’s sides. But he sometimes mistakes doing that
Q. Code Density and Smaller Faster Programs? Memory was very expensive in older computer. So there was a need of less memory utilization, which is it was cost effective to have

Q. How can we write an Interrupt Servicing Routine? The following are the fundamentalthough rigid sequence of steps: 1. Save the system context (flags,registers etc. which
Define Hypertext verses Hypermedia briefly. Hypertext is fundamentally the same as regular text- this can be stored, read, searched or edited along with a significant exception
Define swapping. A process needs to be in memory to be implemented. Though a process can be swapped temporarily out of memory to a backing store and then brought back into mem

State the Protected mode interrupt In protected mode, interrupts have exactly same assignments just like in real mode though the interrupt vector table is different. Instead
