From a previous Windows Guru
I went through the original Windows systems after being a DOS user and am now on a MAC. MacBook to be precise.
Simplicity and the ease of operating multi system tasks. The MAC was indeed more expensive on the original outlay yet again it slid in real easily.
Glad to hear that... and welcome aboard... :-)
Being that you’re a relatively new Mac user... I’ll let you (and others, too) know this. It’s never spelled as “MAC”... as that’s actually something else. It’s always “Mac” ... just to let y’all know...
See below...
The Media Access Control (MAC) data communication protocol sub-layer, also known as the Medium Access Control, is a sublayer of the Data Link Layer specified in the seven-layer OSI model (layer 2). It provides addressing and channel access control mechanisms that make it possible for several terminals or network nodes to communicate within a multipoint network, typically a local area network (LAN) or metropolitan area network (MAN). The hardware that implements the MAC is referred to as a Medium Access Controller.
The MAC sub-layer acts as an interface between the Logical Link Control (LLC) sublayer and the network’s physical layer. The MAC layer emulates a full-duplex logical communication channel in a multipoint network. This channel may provide unicast, multicast or broadcast communication service.
Addressing mechanism
The MAC layer addressing mechanism is called physical address or MAC address. This is a unique serial number assigned to each network adapter, making it possible to deliver data packets to a destination within a subnetwork, i.e. a physical network consisting of one or several network segments interconnected by repeaters, hubs, bridges and switches, but not by IP routers. An IP router may interconnect several subnets.

In other words, the “Mac” has a “MAC” address, too... :-)
