It depends with OS you are using. Easiest way will be by using third part free softweare
for Linux

there is posibility that your distribution has this tool alredy installed or it is in its repository
for Windows

Mac and Windows programs runs similar
* Select a network adapter
* Click "Random" to generate a MAC Address to spoof or write your own
* Click "Change" to change and activate new MAC Address
Linux macchanger run from terminal
sudo macchanger --mac=01:23:45:67:89:AB eth1
where eth1 is network interface of network card that MAC addres you want to hange
you can check all network adapters of you system from console by runing
ifconfig
There is no reason to change a MaC address, only possible answer is if you have commited a criminal offence in IT, such a hacking and want to change your MaC address. Please feel free to correct me, IT is such a large field and can change everyday
The MAC address is the serial number of the network card. This number is unique in the world, and there is no need to change it.The MAC address is the serial number of the network card.

You can't. The MAC address is a permanant part of the device.
you usually don't.
Yes, ofcourse
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.

Hardware address is the MAC address. IPv4 is the IP address. The MAC address is assigned to each network device at the time it's manufactured and does not change. The IP address is manually assigned and can be changed.
IP address remains the same. Mac address changes from router to router.
Doesn't matter if your connected to a LAN or not. The MAC address is hard coded into the NIC and does not change unless software on the computer requires that it changes.
This cannot be done, the MAC address is set in the hardware at the factory to a unique value that no other network device has anywhere in the world and cannot be changed.
A device or computer gets their MAC address from their Network Interface Card (or NIC). This is not something that a user is able to change (See discussion as to why you can change your MAC address). However an IP address can be statically assigned to you which means a network administrator has physically typed out what your IP address and subnet mask is. Another way to get an IP address is through Dynamic Host Configuration Protocol, or DHCP as it is most commonly known as.
