Networking For Dummies, 11th Edition (For Dummies (Computer/Tech))

Product Information

Before you allow devices to connect to your home network you should make some basic changes to the default setup parameters of your router. Your home router is your gateway to the Internet. When viewing your configuration some devices refer to it as the default router whereas other use the term default gateway. However you can usually change the location by using telephone extension cables or longer WAN cables. A home network will have between 1 and 20 devices and a corporate network will have many thousands.

Smart switches generally are controlled via a cloud service. Your mobile is connected to the cloud service server which in turn connects to your smart switch. This is the networking model used on the web and the Internet and on modern large Windows networks.-Diagram below: Having a good understanding of how your network fits together, and works is essential for successful troubleshooting. Questions and Answers It depends on the printer.Older Printers are normally connected to computers and they can then be shared on the network. A network large enough to require more than one switch may also be large enough to require several distinct types of switches:

Router2(config-router)# neighbor 192.168.1.1 Managing enhanced interior gateway routing protocol for Cisco networking Ethernet and Wi-Fi are Data link protocols that are responsible for framing data on the media (cable or wireless). No node has any special role. This was the original networking model of windows networking. (windows for Workgroups)- Diagram below: In my experience most problems are easily diagnosed, and fixed with a little patience and perseverance.

The following example will configure EtherChannel to use group ports 11 and 12 on the switch together using PAgP as the protocol. The same type of command would be used on the switch to which Switch1 is connected. Switch1> enable WDM, CWDM, DWDM… what in the world do they mean? These are abbreviations for terms that are related to fiber optics, which is a kind of high-speed network connectivity method. How the nodes on a network communicate with each other can be very different to how they are physically interconnected. However small home and home office networks will generally be Wi-Fi only. Setting up a Home Network -Components and Structurepassive: Sets the interface to respond to LACP data if it receives negotiation requests from other systems. Of course, computers can exchange information in ways other than networks. Most of us have used what computer nerds call the sneakernet. That’s where you copy a file to a flash drive or other portable storage device and then walk the data over to someone else’s computer. (The term sneakernet is typical of computer nerds’ feeble attempts at humor.) WAN: The second TLA you’re like to encounter is WAN. The WAN is part of the network that connects to the Internet. WAN stands for wide area network. (Okay, fine. Technically, WAN is the third TLA. The first TLA was LAN, and the second TLA was TLA. So that makes WAN the third TLA.)

Don’t be afraid to use EtherChannel on your Cisco network. EtherChannel allows you to take up to eight network ports on your switch and treat them as a single larger link. This can be used to connect servers with multiple network cards that are bonded (or teamed) to a switch, or to connect multiple switches together. There are two main negotiation protocols, Port Aggregation Protocol (PAgP) which is a proprietary Cisco protocol and Link Aggregation Control Protocol (LACP) which is an open standards protocol. Note a new technology that uses mains cable overcomes many of these disadvantages. powerline networking is common on home/small office networks

The web (WWW) is a client server network at the logical level. Peer to Peer and Client Server Networking

MAN is a type of computer network that is larger than a LAN but not up to a WAN (Wide Area Network). It is an intermediary between LAN and WAN. It spans across more areas than in LAN and has a larger amount of computers; it can also be seen as a combination of more than one LANs. Because TCP/IP networks are the most common this is the one that is the most important to understand. are the , they are:” A -Not any more. Wireless connections are getting more popular. See Internet connection methods for more details.If you want to configure either a router or switch to retrieve its IP configuration information from a network Dynamic Host Configuration Protocol (DHCP) server, then you can commands like the following example. Router1> enable However both Wi-Fi and bluetooth are being upgraded to support mesh networking. Networking Topology- Physical vs Logical As a general rule, if your network requires more than a single switch, you should use managed switches. Managed switches are more expensive than unmanaged switches, but when your network grows large enough to require more than one switch, you’ll appreciate the benefits that managed switches provide. Wired networks use Ethernet over UTP cable and tend to be faster than wireless networks, which is an important consideration if you are a gamer. The simple wired home network diagram below shows a minimum setup with a switch and broadband router. On the network: Every computer connected to the network is said to be “on the network.” The technical term (which you can forget) for a computer that’s on the network is a Another term that’s commonly used to mean the same thing is endpoint .
