subtract 20000000H from 30000000H,
because the page table is just a bunch of offsets. So the memory manager would lookup 20000000H in the table, find 10000000H, add'em up and get 30000000H. If that's how it works.

Which address is more important the physical address or the logical address?

In the 8086/8088 the physical address and logical address have the same importance, because they both relate to the address of the operand. It is true that the offset (logical) address is added to the segment address to determine the physical address, but the limitations of the architecture of the processor forces programmers to consider both.If you are talking about a virtual environment, however, such as in the 80286 or higher, then the logical address is more important than the physical address, because the logical address is the address of the operand, while the physical address is (somewhat) arbitrarily assigned by the operating system.


Which three statement are true regarding the encapsulation an de-encapsulation of packets when traveling through a router?

** The router modifies the TTL field, decrementing it by one.** The router maintains the same source and destination IP.** The router changes the source physical address to the physical address of the exit interface


Is it conceivable that some operating system processes might have the entire main memory as their address space?

No, it is impossible. The operating system kernel must remain in memory at all times, including the virtual memory manager, thus no single process can physically occupy every address. Indeed, all unused physical memory is allocated to the virtual memory manager. Processes are allocated addresses within the virtual address space but some of those addresses are reserved for system use only. As such, no process can ever use the entire virtual address space let alone the entire physical address space.


What is the main function of an IP address?

Provide a unique logical address for each device on the network. Each networked device has a globally unique physical address, commonly referred to as the MAC-ID.While the MAC-ID is guaranteed to be globally unique, it refers to a particular hardware, not to a particular device. For example, your PC's Ethernet MAC-ID will change when the LAN card changes, but its logical address (the IP address) may not have to change at the same time. This allows other devices to continue communicating with your PC even after its MAC-ID changed.IP addresses are also grouped into subnets, which supports routing. It messages were sent using MAC-ID (physical) addressing, the message must be repeated into every subnet because the destination device could be anywhere.


What is a page map table?

In operating systems that use virtual memory, every process is given the impression that it is working with large, contiguous sections of memory. In reality, each process' memory may be dispersed across different areas of physical memory, or may have been paged out to a backup storage (typically the hard disk). When a process requests access to its memory, it is the responsibility of the operating system to map the virtual address provided by the process to the physical address where that memory is stored. The page table is where the operating system stores its mappings of virtual addresses to physical addresses.

How can I effectively address and redirect a 3-year-old's habit of chewing on everything?

To effectively address and redirect a 3-year-old's habit of chewing on everything, you can provide them with safe and appropriate chew toys or objects to redirect their behavior. Consistently reinforce and praise them when they use the chew toys instead of inappropriate items. Additionally, try to identify and address any underlying reasons for the behavior, such as teething or sensory needs. Consistent and positive reinforcement, along with patience and understanding, can help redirect the habit over time.

What is present physical address?

A physical address is where you live, or in the case of a business, where the store itself is located. The reason they specify is that sometimes the mailing address is different from the physical address. (a post office box for example)
