Before you allow devices to connect to your home network you should make some basic changes to the default setup parameters of your router. Another common method, but not as simple is to use VLANs. See Understanding and using VLANs Connecting to Internet

The Wireless router will need to connect to the telephone line, cable or fibre network access point in your home.The solution to this issue came in the form of - Classless Inter-Domain Routing (CIDR) and Variable Length Subnet Masking (VLSM). Both of which are key to modern day subnetting. Classless Inter-Domain Routing (CIDR) Online, offline: When a computer is turned on and can access the network, the computer is When a computer can’t access the network, it’s offline. A computer can be offline for several reasons. The computer can be turned off, the user may have disabled the network connection, the computer may be broken, the cable that connects it to the network can be unplugged, or a wad of gum can be jammed into the disk drive. A computer with a Gigabit network card talking to a computer with a 100Mbit/s network card is restricted to 100Mbit/s. Hub is also known as a multi-port repeater due to its similarity with the repeater, though there are specific devices called repeaters. The hub was also used to connect computers and share data amongst them, but it is now majorly used as a repeater to repeat signals from long distances. The hub is known as a layer one device (on the OSI model), likewise the repeater. Ethernet

What is variable-length subnet mask (VLSM)? - Definition from WhatIs ...." 17 Aug. 2014, https://searchnetworking.techtarget.com/definition/variable-length-subnet-mask. Accessed 7 May. 2019. ↩︎ 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. Have you ever experienced an Internet outage or disconnection, a complete local area network (LAN), or a wide area network (WAN) failure? The leading cause of such incidents is network device malfunction or latency in network bandwidth. Routers connect multiple networks together. They also connect computers on those networks to the Internet. Routers enable all networked computers to share a single Internet connection, which saves money. Wi-Fi is a method of connecting computers to a network without the use of cables, i.e. wireless networking, which involves the use of Wi-Fi-enabled computers, access points, wireless routers, etc.

ACLs are used to control traffic flow. They can be used allow or deny the flow of traffic. The two main types of ACLs are: LAN Speed test is a very useful tool for testing your local network speeds. See understanding Home network speeds. A managed on-premises switch lets you configure and monitor your LAN, giving you tighter control of your network traffic. Note a new technology that uses mains cable overcomes many of these disadvantages. powerline networking is common on home/small office networks Internet: The Internet is a huge amalgamation of computer networks strewn about the entire planet. Networking the computers in your home or office so that they can share information with one another and connecting your computer to the worldwide Internet are two separate but related tasks.

Network Devices and Terms

Networks can be wired or wireless with most networks being a mixture of both. Wired vs Wireless Networks

For small campuses or branch offices, converged deployments offer consistency in wireless and wired connections. This deployment converges wired and wireless on one network device—an access switch—and performs the dual role of both switch and wireless controller. For example, if your company has 100 employees, and you have wired two Cat-5e cables to each user’s desk, you’ll need at least 200 1 Gb switch ports to support these users. You’ll also need a few extra ports for things like printers and Wi-Fi access points. Not so easy and fast to setup as it requires running cables. However Homeplug or powerline adapters can be used instead.Like all networks, a Cisco network needs to be properly configured. To do so, you need to know the configuration modes to use when configuring your network. You also should know how to configure an interface, configure a switch management interface, and configure an interface to use DHCP for your Cisco network. Configuration modes for Cisco networking User EXEC mode: When you connect to a Cisco device the default configuration mode is user exec mode. With user exec mode you can view the settings on the device but not make any changes. You know you are in User EXEC mode because the IOS prompt displays a “>”. The most common type of wireless network system, centralized deployments are traditionally used in campuses where buildings and networks are in close proximity. This deployment consolidates the wireless network, which makes upgrades easier andfacilitates advanced wireless functionality. Controllers are based on-premises and are installed in a centralized location. Wired networks use Ethernet as the data link protocol. This is unlikely to change with the IOT, as IOT devices will be predominantly wireless. Wired Networks- Advantages and Disadvantages 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.
