What portion of a MAC address encodes an identifier representing the manufacturer of the card?

The first 3 bytes show this. It's called the OUI, Organizationally Unique Identifier. If you type "getmac" in windows, you should see the 6 byte address, and the first 3 bytes are the ones that you are concerned about. Each OUI is unique to the manufacturer of the network card.

How do you calculate the baud rate for a 72000 bps 64-QAM signal?
QAM-64 encodes 6 bits per symbol (2^6=64). Baud rate = symbol rate = bit rate / bits per symbol = 72000 bps / 6 bits per symbol = 12000
What are three stages that sound passes through when it is computerized?
The three stages are: 1. Digitize or input sound 2. Store the digital data 3. Reproduce or synthesize the sound While the above is true, you may be looking for a different set of steps: 1. The analog audio passes through some type of pre-amp to amplify the signal enough to digitize. 2. The pre-amp passes the analog audio to an analog to digital (A/D) converter. 3. The A/D passes the now digital audio to an encoder that encodes the audio to the desired format and writes it to disk. Sometimes the encoder just writes the uncompressed stream to disk, or sometimes it is encoded live to a format like mp3. This all depends on the specific application. ---- The above answers are true, but here is my textbook's version of the answer: "Sound passes through three stages when it is computerized: # First, the sound is digitized-- that is, converted from analog to digital. # Second, the digital data is stored in a compressed data file. # Third and last, the sound is reproduced or synthesized (digital to analog or digital out)."
How is text stored in a computer?
In a computer, everything is stored in ones and zeros. A single one or zero is called a bit, and a group of 8 bits is called a byte. One byte can be represented as 8 binary numerals, like this: 10011101 Which equals the number 157. It can also be represented in hexadecimal, like this: 9D One byte can store any number between 0 and 255 (00 and FF in hex). In a computer, every text character has a specific number that represents that letter. So, when it sees a particular hex number, it translates that into the text and displays it. This is an overly simplified description. To learn more, read up on bits, bytes, ascii codes and data storage protocols.
What is the importance of Mac addresses?
MAC address is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification, and used in the media access control protocol sub-layer. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number. It may also be known as an Ethernet Hardware Address, hardware address, adapter address, or physical address.
Can you have a dynamic Mac address?
In general, the MAC address is tied to a specific piece of hardware and does not change. It is possible, however, under certain circumstances to change the MAC address. MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address. Although intended to be a permanent and globally unique identification, it is possible to change the MAC address on most modern hardware. Changing MAC addresses is necessary in network virtualization. In this case, the MAC address of the actual NIC is hidden from the network and the network only sees the MAC assigned to the virtual NIC - which can be configured, with some finesse, to be dynamic. It can also be used in the process of exploiting security vulnerabilities. This is called MAC spoofing.
What are the uses of encoder?
it encodes the signal
What is the molecule that encodes the genetic code?
mRNa
What encodes heriditary information?
DNA molecules
The first codon to be deciphered was?
UUU and it encodes phenylalanine
What do genes encode?
Genes encode the instructions for building proteins, which are the primary functional molecules in cells. These proteins determine the structure and function of cells, tissues, and organs in an organism. Additionally, genes also regulate gene expression, cell processes, and overall development.
What is the definition of computer programmer?
A person who encodes machine software.
What is Rec A gene?
that is a gene which encodes for the rec protein A in agrobacterium
Is pdf raster or vector based?
Yes, partially. PDF encodes fonts and EPS graphics that are vector based. It also encodes images, in JPG format for example, which are raster based.
How do you get Mac address?
You don't "Get" one, because you already have one. A MAC Address uniquely identifies your computer's network interface card on the network. If you're asking how do you know what your MAC address is:Windows:Start>Run>type "cmd"in the black window that appears type "ipconfig /all"the MAC address will be listed as "Physical Address" and usually starts with 00-In Mac OS X 10.5 and later, in the left column of the Network preference window that opens, click the name of your connection (e.g., AirPort, Ethernet, Built-in Ethernet). Click the Advanced... button, and in the sheet that drops down, click either the Ethernet or AirPort tab. The string of letters and numbers next to "Ethernet ID:" or "AirPort ID:" is your MAC address.In Mac OS X 10.3 or 10.4, in the Network preference window that opens, make sure the pull-down menu next to "Show:" lists your connection (e.g., AirPort, Built-in Ethernet). Under the Ethernet or AirPort tab, the string of letters and numbers next to "Ethernet ID:" or "AirPort ID" is your MAC address.Alternatively, you could use "ifconfig -a"Linux:Open a shell, use "ifconfig -a". This will display your current network settings for each interface available on your computer.An example of what a MAC address would look like:00-FF-20-58-C9-60*NOTE* all devices that access the internet have a MAC address (iPhone, PS3, PSP, Switches, Firewalls, Routers, cable modems, cell phones, etc)Wikipedia:In computer networking, a Media Access Control address(MAC address) is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification, and used in the Media Access Control protocol sub-layer.
