There are 48 bits, or six bytes included in a MAC address. MAC stands for Media Access Control, and its address are written in a MM:MM:MM:SS:SS:SS format.Know More
In this format, the first three bytes written into the formula are provided by the manufacturer. It is the assigned ID number of the manufacturer. The second three bytes in this sequence are a serial number, also provided by the manufacturer, but specific to the device. MAC is also referred to as the physical address of a device.
To find the MAC address on a Windows device, the user would type "ipconfig /all" into the command prompt. For UNIX and Linux machines, the MAC can be found by using the commands "ifconfig -a", "ip link list" or "ip address show". On Apple iOS, MAC addresses can be found by opening the System Preferences folder and selecting the Network option.
MAC is part of TCP/IP, and is considered the hardware support model of this protocol. An IP address is considered the software support for this network protocol. One of the main differences between the two is that IP addresses are assigned, typically by a network administrator. MAC addresses are supplied by the manufacturer prior to implementation by the end user.Learn more about Computers & Hardware
The data link layer's primary function is to ensure data is received by the correct device in a network using hardware addresses, called MAC address, and then convert that data into bits for the physical layer to transmit. It also manages error notification, flow control and network topology.Full Answer >
In Internet networking, a logical address is an IP address that may be assigned by software in the server or router or may be user-assigned, in contrast to the physical address (also called the MAC address) which is set in the hardware at the factory, and unalterable. The logical address is then used by the network layer 3 (or Open Systems Interconnection - OSI - layer) protocols.Full Answer >
The Grab utility, included with the Macintosh operating system, allows users to capture all or part of the screen and save the image, similar to the Windows snipping tool. The application is located in the Utilities folder, which is inside the Applications folder.Full Answer >
You can make your Mac run faster by decluttering the hard drive. Apple computers need at least 10 gigabytes of disk space to run efficiently and keep the system from slowing down. Uninstalling unused programs and removing cluttered icons from the desktop can improve overall start-up and multitasking speed.Full Answer >
