Assuming you use Airport, you click on the Airport icon in the menubar, select "Create Network", give it a name and channel, and click OK.
It may be possible, but NOT advisable
Yes, by its mac address.
A Media Access Control address (MAC address) is what identifies your computer on a network. You should be able to find it within your network preferences or in a summary of the computers status.
Yes you can see other computers in a wireless network, each device has it's own unique MAC-address which describes to the computer what type of device is connected to the network. Using the 'Network' feature on the computer gives the person a graphical view of who is connected to the Network, this can be done by going to: Start, 'Network'.
The MAC address is the serial number of the network card (NIC). It is used in network communication (for example, in Ethernet networks) as a unique identifier for every computer (and other hosts).The MAC address is the serial number of the network card (NIC).

The Media Access Control - MAC Address is a number, created by the manufacturer, which identifies your computer on a network. If you have a wireless network, for example, you may want to add the MAC address for each computer you want to connect to the network, and tell the router to only allow these computers to connect, to prevent unknown computers connecting to your network.
The MAC address is a unique identifier for a networking card. Each networking card has a MAC address assigned to it during it's manufacturing, and thus it does not change when a computer moves between networks (unlike an IP address which is assigned by the network). A few things to note: - A computer only has a MAC address if it has a physical or virtual network card - A computer has as many MAC addresses as it has networking cards - MAC addresses CAN be modified before being broadcast to the rest of the network, however generally this results in the computer not receiving intended traffic and requires specialized software
Each computer has a unique name, IP address and MAC address. (not MAC as in McIntosh.)
There's no really much harm in actually showing someone your MAC Address. All i make MAC Address is a 12 digital and letter code that identifies the network card. If someone had your MAC Address they could try and gain access to your network. But that's all. *edit* Yeah, like what the previous person said. If someone got your MAC address and IP address, when you turn on your computer they could try to MAC spoof their way into your network by making their computer looking like your computer.

Every piece of equipment (computers, printers etc.) has a MAC (Media Access Control) address which identifies it when it is connected to a network. To spoof the MAC address is to supply the network with a different address than the one allocated for your computer so you are pretending to be another computer.
Someone can spoof it using a MAC spoof attack. This is where an attack acquires your MAC address, sends a disconnect signal to your computer to disconnect you from the network, and then connects onto the network with your MAC address, making the network's authentication systems think it is you, but it is really a hacker. When you try to get back on, you find that you can't because the network won't allow two computers with the same MAC address to be connected on the network.
