What is logical address space?

Logical Address Space is the set of all logical addresses generated by CPU for a program whereas the set of all physical address mapped to corresponding logical addresses is called Physical Address Space.

What is logical address in memory management?

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 address space in memory?

Address space is the amount of memory allocated for all possible addresses for a computational entity, such as a device, a file, a server, or a networked computer. Address space may refer to a range of either physical or virtual addresses accessible to a processor or reserved for a process.

What are the two parts of logical address?

A logical address consists of two parts: A page number in which the address resides, and an offset from the beginning of that page. ( The number of bits in the page number limits how many pages a single process can address.

Is logical address same as IP address?

An IP address is a logical address that is assigned by software residing in the router or server, and that logical address can change from time to time. In order to locate a device in an IP network, the logical IP address is converted to a physical address by a resolution protocol (see ARP).

Why is logical addressing needed?

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.

Is logical address space can be larger than physical address space?

Logical Address space can be larger than physical address space. Explanation: The statement is true. Since, a part of the program needs to be in memory for the process of execution, the logical space can therefore be much larger than the physical address space.

Is address space the same as memory?

A computer’s address space is the total amount of memory that can be addressed by the computer. The term may refer to the physical memory (RAM chips) or virtual memory (disk/SSD). For example, a 32-bit computer can address 4GB of physical memory and as much as 64TB of virtual memory.

Is memory and address same?

No. They are entirely independent. An 8 bit data bus almost always has way more than 8 address lines! Number of Address lines dictate how much memory you can access (in bytes).

What is the difference between logical addressing and physical addressing how they are used in networks for identification?

The basic difference between a logical and physical address is that during program execution, the logical address is created by the CPU, while the physical address refers to a memory location. The address is used as a physical memory location access reference.

What’s the difference between Mac and IP addresses?

The main difference between MAC and IP address is that MAC Address is used to ensure the physical address of the computer. It uniquely identifies the devices on a network. While IP addresses are used to uniquely identifies the connection of the network with that device takes part in a network.

What is the difference between logical address and physical address?

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.
