It happens when the number is greater than the length (when it is not within the range) . so for example: Consider the following segment table:
Segment: Base: Length:
0 219 600
1 2300 14
2 90 100
3 1327 580
4 1952 96
What are the physical addresses for the following logical addresses?
a. 0, 612
b. 1, 12
c. 2, 100
d. 3, 200
e. 4, 98
Answer:
a. illegal reference, trap to operating system
b. 2300+12=2312
c. 90+100=190
d. 1327+200=1527
e. illegal reference, trap to operating system
a. is illegal because the Base (the start) is 219 and the Length (the finish) is 600, if you add the base and the length you get 819. if you add the logical address which is 612 to the base which 219 you get 831 which greater than 819. that is when we get illegal reference. Same apply to e.
An extended machine is usually in reference to a computer. It commonly is in reference to the OS or operating system of the computer.
An operating system loads via the memory of a computer. The specific area that gets the operating system to load is called the boot loader.
computer software with refrence
Then it doesn't work correctly.
When MBR fails then the operating system will not load.
1. What is the frame of reference and operating domain for your business organization and systems, products, or the services it provides?
Yes, 3 levels: hardware, operating system, application
When you don't have any operating system, the computer won't boot. You can only access BIOS setup or your boot-loader. In simple words, you can't do anything with it.
this is the systems harddrive that makes the operating system work
it may raise noise to an illegal level
An operating system is a software which is used to manage or open all the softwares in the computer/deviceANS2:A computer's operating system is a set of programs that controls the hardware. It is certainly software even if it happens to be in some non-writeablestorage such as an e-prom.
