Who makes memory addresses?
Those who address on the nature of memory. :-)
Why you need memory physical address and memory logical address?
Physical Address refers to Storage location on Physical Memory wheres Logical Addressing is used by Memory Managing Programs to refers addresses from Physical Memory and Virtual Memory.
What is logical address space and physical address space?
Logical address is the address generated by the CPU (from the perspective of a program that is running) whereas physical address (or the real address) is the address seen by the memory unit and it allows the data bus to access a particular memory cell in the main memory. All the logical addresses need to be mapped in to physical addresses before they can be used by the MMU. Physical and logical addresses are same when using compile time and load time address binding but they differ when using execution time address binding.
Physical address and logical address?
A logical (or virtual) address is a reference to a memory location independent of the current assignment of data to memory; a translation must be made to a physical address before the memory access can be achieved. A relative address is the address expressed as a location relative to some known point, usually the beginning of the program. A physical address, or absolute address, is an actual location in main memory.
What kind of memory addresses does a memory management unit generate?
- An MMU (memory management unit) generates physical address. - A CPU (central processing unit) generates a logical address.
What is the difference between a physical address and a mailing address?
Real memory uses Physical addresses.These are the members that the memory chips react to on the bus. Virtual addresses are the logical addresses that nrefer to a process' address space. Thus, a machine with a 16-bit word can generate virtual addresses upto 64K, regardless of whether the machine has more or less memory than 64 KB
What is address space?
An address space is a range of discrete addresses, all of the address locations available in a particular named subset of a computer's memory.
Compare pegging with segmentation regarding the amount of memory required by the address translation structures to convert virtual addresses to Physical addresses?
yes
Memory address register is used to store?
memory addres register is used hold data addresses that refer to the data portion of the memory(by umar farooq.pk) memory addres register is used hold data addresses that refer to the data portion of the memory(by umar farooq.pk)
What is the purpose of the address bus?
An address bus carries memory addresses so that Data can be transported and deposited/retrieved from the correct places.
How many memory addresses does this number of address lines allow the 8086 to access directly?
The 8086/8088 has 20 address lines. It can access 220, or 1MB, or 1,048,576 bytes of memory.
What is the role of an address when used in the context of computer memory?
In the context of computer memory, an address is used to access the computer's primary storage memory. These addresses consist of fixed-length digits displayed as unsigned integers.
