How is physical address determined from an offset address?

How is physical address determined from an offset address?

This 16-bit address with respect to the part (segment of 64KB) of the memory bank is called the offset. So, Physical Address = Base Address + Offset.

Why does CPU generate logical address?

Logical Address is generated by CPU while a program is running. The logical address is virtual address as it does not exist physically, therefore, it is also known as Virtual Address. This address is used as a reference to access the physical memory location by CPU. For example the CPU generates a logical address 346.

What is the difference between logical and physical addresses?

The logical address is a virtual address and can be viewed by the user. The fundamental difference between logical and physical address is that logical address is generated by CPU during a program execution whereas, the physical address refers to a location in the memory unit.

What is the use of logical address?

Logical address is used to reference to access the physical memory location. A logical address is generated so that a user program never directly access the physical memory and the process donot occupies memory which is acquired by another process thus corrupting that process.

Which address is used on Layer?

Logical addresses are created and used by Network layer protocols such as IP or IPX. The Network layer protocol translates logical addresses to MAC addresses. For example, if you use IP as the Network layer protocol, devices on the network are assigned IP addresses such as 207.120.

What is a logical memory address?

In computing, a logical address is the address at which an item (memory cell, storage element, network host) appears to reside from the perspective of an executing application program. A logical address may be different from the physical address due to the operation of an address translator or mapping function.

What is virtual memory how a logical address is explain with example?

Definition of Logical Address The logical address is virtual as it does not exist physically. Hence, it is also called as Virtual Address. This address is used as a reference to access the physical memory location. The set of all logical addresses generated by a programs perspective is called Logical Address Space.

What is difference between internal and external fragmentation?

Internal fragmentation happens when the method or process is larger than the memory. Internal fragmentation occurs when memory is divided into fixed sized partitions. External fragmentation occurs when memory is divided into variable size partitions based on the size of processes.
