In computer networking, MAC address filtering is a network access control method whereby the MAC address assigned to each network interface controller is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the ...
The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed. However, many drivers allow the MAC address to be changed. Additionally, there are tools which can make an operating system believe that the NIC has the MAC address of a user's choosing. The process of masking a MAC address is known as MAC spoofing.
In fact, even for the Macintosh 512K to use the drive, it requires an additional file in the System Folder on a special startup disk which adds additional code into memory during startup. A startup routine also allows the Mac to check for the presence of a System file on the Hard Disk, switch over to it and eject the startup disk.
This drive was fitted into an external case as the Macintosh 800K External Drive (M0131), which was slimmer than the earlier 400-kilobyte drive. It could be used with Macintosh models except for the original 128K, which could not load the HFS disk format. The drive supported the older 400-kilobyte single-sided disks allowing them to be shared.
The term message integrity code (MIC) is frequently substituted for the term MAC, especially in communications [1] to distinguish it from the use of the latter as media access control address (MAC address). However, some authors [2] use MIC to refer to a message digest, which aims only to uniquely but opaquely identify a single message.
However, S.M.A.R.T. parameters alone may not be useful for predicting individual drive failures. [16] While several S.M.A.R.T. parameters affect failure probability, a large fraction of failed drives do not produce predictive S.M.A.R.T. parameters. [16] Unpredictable breakdown may occur at any time in normal use, with potential loss of all data.
The United States passport card is an optional national identity card and a travel document issued by the U.S. federal government in the size of a credit card. [3] Like a United States passport book, the passport card is only issued to U.S. citizens and U.S. nationals exclusively by the U.S. Department of State.
