1). Finding Your MAC Address On Wired And Wireless Network Cards By : Darren Miller
The Answer To The Media Access Control Question ---------------------------- Over the past few weeks I have received quite a few e-mails about Ethernet cards, both wired and wireless, and more specifically, about Media Access Control (MAC) addresses. I think the main reason I’ve received so many questions about Ethernet cards and MAC addresses is people trying to secure their home wireless networks and their desire to use MAC address filtering.

2). Cisco CCNA Certification Exam Tutorial: Frame Relay DLCIs And Mappings By : Chris Bryant, CCIE #12933
Passing the CCNA is tough, and one of the toughest parts is keeping all the acronyms straight! Frame Relay has plenty of those, and today we're going to examine what DLCIs do and how they're mapped on a Cisco router. Frame Relay VCs use Data-Link Connection Identifiers (DLCI - pronounced "del-see") as their addresses. Unlike other Cisco technologies, VCs have only a single DLCI in their header.

3). Network+ Certification Exam Tutorial: ARP and Proxy ARP Explained By : Chris Bryant, CCIE #12933
In yesterday's Network+ tutorial, we talked about the importance of Address Resolution Protocol (ARP) in today's networks. A host PC must have the MAC and IP addresses of a remote host in order to send data to that remote host, and it's ARP that allows the local host to request the remost host to send the local host its MAC address through an ARP Request.

4). Network+ Certification Exam Tutorial: DHCP And RARP By : Chris Bryant, CCIE #12933
Part of passing the Network+ exam is mastering the many different protocols and services you're introduced to in your studies, and that's especially hard when two protocols do much the same thing! That's the case with RARP and DHCP, so let's take a close look at these two protocols and why we use them in the first place. Whether you've been around networks for a while or are just getting started with your IT career, you'll quickly notice that many basic tasks in networking can be handled either statically or dynamically.

5). Network+ Certification Exam Tutorial: Address Resolution Protocol (ARP) By : Chris Bryant, CCIE #12933
When you're studying for the Network+ exam, you've got to master the fundamentals of networking, because the Network+ is a hard exam to pass due to the range of information covered. One such fundamental is the Address Resolution Protocol, commonly referred to as ARP. ARP operates at the Data Link layer of the OSI model, and its purpose is often overlooked.
