This 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses.
IP addresses range from 0.0.0.0 to 255.255.255.255, with the numbers 0-255 represented in each of the four segments of the address. This results in a total of 4,294,967,296 possible addresses. Note that many addresses are reserved for private or multicast use. Therefore, the actual number of available addresses is much lower than the 4.3 billion theoretical addresses.
MacBook Pro comes with macOS, the most advanced desktop operating system in the world. macOS is designed to take full advantage of the powerful hardware in every Mac, and to deliver the most intuitive and seamless experience possible. You can buy MacBook Pro from: Microprokey
Mac answer: Your hard drive might be damaged. Boot up your mac with the DVD-disc or USB-drive that came with your mac and let Disk Utility try to repair your drive. If successful you will be able to start your Mac again as normal. If you are on Apple Care or if you are on your first year within purchase, it is advised to backup as much data as possible before taking it to an Apple Certified Repair shop to get yourself a new Hard drive.

Apple wanted to be the software, and hardware company. That way Mac OS X is built for the Mac computers.
To confirm which version of the Mac OS is being used by a Mac computer click on the Apple menu icon (top left of screen) and select About This Mac.
The original IEEE 802 MAC address comes from the original Xerox Ethernet addressing scheme. This 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses.
802.11 use MAC addresses, which are the same as IP addresses in some networks
Address Resolution Protocol (ARP)ARP is primarily used to translate IP Addresses to Ethernet MAC Addresses.
yes they do.

Routers don't use MAC addresses for routing. They use IP address.
A MAC address is unique to your ethernet card. MAC addresses are used within an Ethernet network to uniquely identify the source and destination of Ethernet frames. ARP (Address Resolution Protocol) is used on IP networks to map IP addresses to MAC addresses within an Ethernet network.

ARP, or Address Resolution Protocol, defined by RFC 826.
Ethernet addresses are 48 bits long - not 32 bits long like IP addresses. Different single network standards have different address lengths. Ethernet addresses are called MAC addresses for other reasons, Media Access Control.
