Product Information

Each of these topologies has advantages and disadvantages this Network topologies article has a really good overview of each topology along with advantages and disadvantages. However both Wi-Fi and bluetooth are being upgraded to support mesh networking. Networking Topology- Physical vs Logical Computer networks can be classified based on different attributes such as physical size, mode of connection, types of devices, etc. For an easy introduction, let’s look at its classification in terms of physical size. You will often hear the following. 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.

LAN: Networks are often called LANs, short for local area network. In the image above, the LAN consists of the home router and the computers and iPad that are connected to it directly via cable or wirelessly. 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.There are two basic types of switches to choose from as part of your networking basics: on-premises and cloud-managed. Another common method, but not as simple is to use VLANs. See Understanding and using VLANs Connecting to Internet This usually involves pressing a button on the wi_fi router and a corresponding WPS connection button on the Device. Because TCP/IP networks are the most common this is the one that is the most important to understand. are the , they are:” 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

The web (WWW) is a client server network at the logical level. Peer to Peer and Client Server Networking This allowed networks to be aggregated, reducing the number of entries in the IP routing tables, whilst also allowing for greater efficiency in IP route processing. Variable Length Subnet Masking (VLSM) This is the networking model used on the web and the Internet and on modern large Windows networks.-Diagram below: 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.If you are connecting two switches together, then you will want to allow all configured VLANs to pass between the two switches. This is accomplished by implementing a trunk port. To configure port 24 on your switch to be a trunk port, you will use the following code: Switch1> enable Because TCP/IP networks are the most common the TCP/IP model is the most important one to understand. The levels are: 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.

extending your Wi-Fi coverage by installing additional Wireless Access Points or a more powerful access point. Common connection technologies like Wi-Fi, Bluetooth etc are designed to work using a particular network topology. However if you do require devices on the Internet to connect into your network (often required by gamers) then you can configure port forwarding. The following sentence threw me off and I wasn’t able to completely understand what you were trying to say…Having a good understanding of how your network fits together, and works is essential for successful troubleshooting. Questions and Answers LAN Speed test is a very useful tool for testing your local network speeds. See understanding Home network speeds. Tks for pointing that out. I had to read it several times to understand what it meant. It refers to the TCP/IP model being the most important one to understand. So if the internet goes down there is no connection from your mobile to the smart switch unless the switch allows local access and that depends on the switch itself. In a Client Server network a server has a special role e.g file server, domain controller, web server etc.

Access switches: An access switch is a switch that typically has a large number of 1 Gigabit (Gb) ports whose job is to connect individual devices such as computers and printers to the network. In this tutorial you will learn the basic networking technologies, terms and concepts used in all types of networks both wired and wireless, home and office. VLAN is a method of logically separating a LAN and making it look like different networks in one. Physically its one network, but logically they are different networks. This is done by a switch (only when configured to do so). WI-FI

Securing your Cisco network by applying an access control list

Router1(config) #access-list 101 permit tcp 192.168.8.0 0.0.0.255 any eq 443 Securing your Cisco network by applying an access control list 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. Because the Wireless Router provides the Wireless access point then you should install it in a central location, if possible, to get the best wireless reception.
