What is a MAC address and why is this needed for devices on a network?
The MAC address (short for media access control address) is the worldwide unique hardware address of a single network adapter. The physical address is used to identify a device in computer networks. Since MAC addresses are assigned directly by the hardware manufacturer, they are also referred to as hardware addresses.
Why would a device have two IP addresses?
This could be because you want your computer to be able to talk on two separate networks, or because you have both a wired and wireless network interface, and have connected both. Security-wise, a computer with 2 IP addresses, especially a server, can choose which IP address to offer for which service.
Why do we need both IP address and port address for process communication?
9 Answers. IP address is address of the system in the Network. Port is address of the service within the System. So IP address + Port defines address of the particular service on the particular system.
Why do we need IP address?
Why DO WE NEED IP ADDRESSES? IP addresses are the numbers that enable our computers, servers, telephones, cameras, printers and sensors to communicate with each other. Without IP addresses, we would have to copy data from device to device manually, using CDs, DVDs, hard disks or flash storage, such as a USB drive.
Why do I have 2 IP addresses on my IPAD?
It’s on the cellular network, but it is also on the WiFi network. Because it’s on two networks, it has two IP addresses. A typical phone might have one IP address for the WiFi interface (which it has only when actually connected to WiFi) and one IP address for the cellular phone interface.
What is difference between IP address and MAC address?
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.
Why do devices on a network need addresses?
Devices in a network require addresses so that they can be able to be identified uniquely. For communication to take place in a network, the devices must be able to recognize each other. This is the reason that these devices are assigned addresses.
Why MAC address is required when IP address is there?
So again, IP Addresses are logical and routeable addresses. And that’s why computers have both MAC Addresses and IP Addresses. MAC Addresses handle the physical connection from computer to computer while IP Addresses handle the logical routeable connection from both computer to computer AND network to network.
