In html programming, colors can be represented by a 6-digit hexadecimal number: FFFFFF represents white whereas 000000 represents black. In hex, these can be represented in a friendlier fashion, ranging from 00 to FF. This means one byte can carry binary values from 0000 0000 to 1111 1111. Each hex digit represents four binary digits therefore, hex is a language to write binary in an abbreviated form.įour binary digits (also called nibbles) make up half a byte.
Hex is used in mathematics and information technologies as a more friendly way to represent binary numbers. The letters are used because of the need to represent the values 10, 11, 12, 13, 14 and 15 each in one single symbol.
These are the 10 decimal digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and the first six letters of the English alphabet (A, B, C, D, E, F). As a base-16 numeral system, it uses 16 symbols. The hexadecimal system (shortly hex), uses the number 16 as its base (radix). Thus, the number 2345.67 can also be represented as follows:.Meanwhile, the digit 6 after the decimal point is in the tenths (1/10, which is 10 -1) and 7 is in the hundredths (1/100, which is 10 -2) position.2 is in the position of thousands (10 3).3 is in the position of hundreds (10 2).The digit 5 is in the position of ones (10 0, which equals 1),.The Hindu-Arabic numeral system gives positions to the digits in a number and this method works by using powers of the base 10 digits are raised to the n th power, in accordance with their position.įor instance, take the number 2345.67 in the decimal system: The difficulty of representing very large numbers in the decimal system was overcome by the Hindu–Arabic numeral system. Therefore, it has 10 symbols: The numbers from 0 to 9 namely 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.Īs one of the oldest known numeral systems, the decimal numeral system has been used by many ancient civilizations. It uses the number 10 as its base (radix). Select Advanced, and your wireless network card's MAC Address should appear here.The decimal numeral system is the most commonly used and the standard system in daily life.The value against this field is your MAC Address.Your MAC Address should be in this format: 00-14-22-04-25-37.The value displayed next to it is your MAC Address.

CONVERT MAC ADDRESS TO HEC FOR MAC
For example, let's say a network card manufactured by dell has a physical address: 00-14-22-04-25-37, in this address, 00-14-22 is the OUI of Dell which identifies that the device is by Dell. OUI is always the same for NICs manufactured by the same company. The first three sets of two hexadecimal numbers in a MAC Address identifies the card manufacturer, and this number is called OUI (organizationally unique identifier). There are several NIC manufacturers some well-known of them are Dell, Cisco, Belkin. The physical address is stored into the NIC by its manufacturer, that is why this address is also called a burned-in address (BIA) or ethernet hardware address. The network adapters or network interface cards always come with a MAC address which is fed into hardware, usually in read-only memory (ROM), or BIOS system. MAC Address usually consists of six groups of two hexadecimal digits. It identifies the hardware manufacturer and is used for network communication between devices in a network segment. It is also known as a physical or hardware address. MAC Address or media access control address is a unique ID assigned to network interface cards (NICs). All this information is useful if you want to verify the generated mac address with the original vendor of this device in OUI vendor database. Finding the mac address from this database tells us which manufacturer originally manufactured this device and what is the prefix, postfix of a given mac address, moreover it tells us what country was this device manufactured. The MAC Address vendor database consists of a list of mac addresses of all devices manufactured till date. MAC Address Lookup Tool searches your MAC Address or OUI in mac address vendor database.
