Why IP address is called logical and MAC physical?

There is no assurance that the device always has the same IP address. The IP address is not directly linked to any devices. As a result, it is referred to as a logical address. However, there is a MAC address provided by the hardware interface vendor.

Why IP address is known as logical 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. For example, a laptop is likely to be assigned a new IP when it starts up in a different hotspot (see DHCP).

Is logical address same as MAC Address?

MAC Address is a physical address. IP Address is a logical address.

What is the difference between a MAC Address and an IP address?

The physical address — which is also called a media access control, or MAC, address — identifies a device to other devices on the same local network. The internet address — or IP address — identifies the device globally. A network packet needs both addresses to get to its destination.

Is MAC Address a physical layer?

MAC Address (or Hardware address or Physical Address): MAC address works at the data link layer of the OSI model and allows computers to uniquely identify themselves in the network at a relatively lower level.

Why do we need Mac Mcq?

MAC addresses are very useful in diagnosing network issues. Explanation: MAC address is used as a network address for most IEEE 802 network technologies, including Ethernet and Wi-Fi. Logically, MAC addresses are used in the media access control protocol sub layer of the OSI model. 9.

What is another term for a 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.

What is logical addressing in networking?

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 MAC address (physical address)?

MAC Address is also known as Physical Address of a network device. In IEEE 802 standard, Data Link Layer is divided into two sublayers – MAC address is used by Media Access Control (MAC) sublayer of Data-Link Layer.

What is the difference between MAC address and IP address?

Both MAC Address and IP Address are used to uniquely define a device on the internet. NIC Card’s Manufacturer provides the MAC Address, on the other hand Internet Service Provider provides IP Address. The main difference between MAC and IP address is that, MAC Address is used to ensure the physical address of computer.

What is the physical address of a network device called?

Answer Wiki. Every network device has two types of addresses, one called the logical address — in most cases this is the IP address — and the other one being the physical address — also known as the MAC address. The IP address is an address bound to the network device, i.e., computer, via software.

Why is an IP address called a logical address?

An IP address is a “logical” address because it declares and identifies that device as part of the overall logic system we call TCP-IP, (Transmission Control Protocol – Internet Protocol) and allows it to communicate with other such devices.
