To calculate the physical address from a logical address, you can use the base address and offset. Add the base address to the offset to get the physical address. This process is commonly used in computer systems to translate logical addresses to physical addresses for memory access.

How do you calculate the virtual address space for a given system?

To calculate the virtual address space for a given system, you need to determine the number of bits used for addressing in the system's memory architecture. The virtual address space is typically 2 raised to the power of the number of bits used for addressing, which gives you the total number of unique memory addresses that can be accessed by the system.

Is the given logical formula satisfiable (sat) or unsatisfiable (unsat)?

The given logical formula is satisfiable if there is at least one assignment of truth values to its variables that makes the formula true, and unsatisfiable if no such assignment exists.

How page table size calculate when virtual address space and page size and page table entry size given?

To calculate the page table size, divide virtual address space by page size and multiply by page table entry size. Example: for a 120MB address space with a 4KB page size, you require 30,720 page table entries. If a page table entry is 4 bytes, you require a total page table size of 122,880 or 120KB.

How do you calculate the miss rate in a given scenario?

To calculate the miss rate in a given scenario, divide the number of cache misses by the total number of memory accesses. Multiply the result by 100 to get the miss rate as a percentage.

What IP address is a network address?

internet provider Its actually internet protocol. Every computer on the network has to have its own address, this address is called the IP address. Though since you asked what is IP. IP is just a protocol.

Differentiate physical and logical addresses?

Physical address refers to the actual location of data in memory hardware, while a logical address is a virtual address that the CPU uses to access memory. Physical addresses are unique and specific to a particular memory location, whereas logical addresses can be mapped to different physical addresses by the memory management unit.

How can calculate page number and offset from logical address equals 2000 and page equals 4KB?

To calculate the page number and offset from a logical address given that the page size is 4KB, you first need to divide the logical address by the page size. In this case, 2000 / 4096 = 0.4883. The whole number part is the page number (0 in this case), and the remainder is the offset (0.4883 * 4096 = 2000 bytes).

Consider a logical address space of eight pages of 1024words each mapped onto a physical memory of 32 frames how many bits are there in the logical address?

As was given for a 4 Page, 1024 words & 64 frames (shown below) 4 pages -> 2^2 bits 1024 bytes -> 2^10 bits 64 frames -> 2^6 bits Therefore: Logical memory = 2+10=12 bits Physical memory = 10 +6 =16 bits The answer for this problem is 13. 8 pages -> 2^3 bits 1024 bytes -> 2^10 bits 32 frames -> 2^5 bits Therefore: Logical memory = 3+10=13 bits (Page + Word) Physical memory = 10 + 5 =15 bits (Word + Frame)

Why the first logical address in a network is normally not assigned to any device?

Usually the highest address in any given subnet (all 1's in binary) is that networks broadcast address and the lowest address in that same subnet (all 0's in binary) is that networks net-ip (in other words, the address of "the network"). These two addresses are typically never assigned to a host.
