How can calculate page number and offset from logical address equals 2000 and page equals 4KB?
u have not mentioned the unit with logical address, if its byte , u cannot have such small memory , as page size is bigger i.e 4*1024=4096bytes
Assuming it is 2000kb=2000*1024=2048000bytes
page no will be :
2048000/4096=500 its the page no, and to
calculate the offset :
2048000%4096=0;

How to calculate the oxidation number?
To calculate the oxidation number of an element in a compound, follow these steps: 1. Assign known oxidation numbers, such as +1 for hydrogen and -2 for oxygen. 2. Use algebraic rules to solve for the unknown oxidation number based on the compound's overall charge or known oxidation numbers of other elements. 3. Remember that the sum of oxidation numbers in a compound equals zero, or equals the compound's net charge if it is an ion.
What is the mass number and how do you calculate it?
The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.
How do you calculate the number of protons neutrons and electrons of an atom?
The charge of an ion can be calculated by adding up the protons and subtracting the electrons. When oxygen with 8 protons has 8 electrons it is neutral, when it has 7 electrons it is positively charged.
Whats a type of number that equals the amount of protons inside a nucleus and electrons outside a nucleus?
Atomic number represents the number of protons in the nucleus of an atom, which also equals the number of electrons outside the nucleus.
The combined number of protons and neutrons?
The combined number of protons and neutrons is known as the mass number of an atom. It can be used to calculate the atomic mass by adding the total number of protons and neutrons in the nucleus of an atom.
How do you calculate the page table size in operation system?
The number of bits in the offset field is determined by the page size. ... Calculate the number of bits in the page number and offset fields of a logical address. ... must have a page table base register that is accessible by the operating system.
What kind of address is a logical number that uniquely identifies a specific node?
Ip address
Can physical address and virtual address be same?
your question is wrong. it should be "can physical address and logical address be same" answer is no because logical address is the combination of page number and offset whereas physical address is the combination of physical page[frame] and offset
Formula to get logical to physical address in paging?
(frame no * page size) + offset value = physical add where frame value is the value present in the corresponding page number offset value is the last n bits of the logical address page no is the first m-n bits of logical address 2^m is the logical address 2^n is the page size
How does CPU generate logical address?
Lets take the scenario of CPU MMU (memory management unit) Physical Memory.CPU generates the logical address as Page number + Page offset.Of course this address will point to some physical address.Page number is for the index in page table (for base address).The base address + offset is sent to MMU which is mapped to the corresponding physical page.
How do you calculate number of address lines needeed for 1 MB?
20 address lines are required
How do you calculate shortest seek time first algorithm Average?
The first step is to convert the logical device number into a physical address. Then you must schedule an IO request. You improve the seek time by testing the IO numbers to see what gives the best results.
How do you calculate paging address?
To calculate a paging address, you need to divide the virtual address into two parts: the page number and the offset. The page number is obtained by dividing the virtual address by the page size, while the offset is found by taking the modulus of the virtual address with the page size. The page table is then used to translate the page number into a corresponding physical frame number, which is combined with the offset to form the final physical address.
How do you calculate half of a number?
To calculate half of a number, divide the number by 2. For example, if the number is 8, you would perform the calculation 8 ÷ 2, which equals 4. This method applies to both whole numbers and decimals.
What is the next logical number on the sequence 1 1 2 3 5?
The sequence provided is the Fibonacci sequence, where each number is the sum of the two preceding ones. In this case, after 1, 1, 2, 3, and 5, the next number is 3 + 5, which equals 8. Therefore, the next logical number in the sequence is 8.
A process's port number plus its host machine's IP address equals the process's?
socket
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.
