Cable supply offers netgear switches that deliver innovative switching solutions to consumers of all kinds. This ranges from small businesses, business to business service providers, and to major corporations. Switches/Switching Switches send data packets to one or many devices through ports for communicating in computer networks. Network switches differ from electrical switches and ‘managed’ switches differ from ‘unmanaged’ switches in many ways, and for computer networks, this means the difference of critical data getting through or not. Managed switches can control LAN traffic (Local Area Network), where unmanaged switches cannot. Cable Supply recommends only using managed switches because they are ‘smart,’ given their ability to configure the switch to do exactly what is needed. Managed Switches enhance security and to configure settings for a VLAN (Virtual LAN), a single Layer 2 network that is separate so that packets pass between them via one or more routers. Packets are any unit of data that is routed between an origin and a destination on any other packet-switched network. Managed switches are Layer 2 devices, just like unmanaged switches, and both operate at Data Link Layer or Layer 2, which handles physical addressing or MAC addresses. MAC addresses (Media Access Control) are unique identifiers like telephone numbers. Layer 2 devices look only at the MAC address of a data packet's Ethernet frame. Systems communicating over Ethernet, stream data into shorter pieces called protocol data units (PDU), and each one contains both the source and destination address (MAC address). Prices for managed switches are much less expensive now so even homeowners are installing switches for their computer networks to improve performance and speed. Cable Supply sells only switches since HUBs are obsolete. Switches come in different sizes, 12-48 (larger for global networking), and different speeds of 10, 100, and 1,000 megabits. An unmanaged switch allows Ethernet devices to communicate with one another, such as a PC or network printer, as in “plug and play.” The drawback is they are manufactured with a fixed configuration with no changes allowed. This control and ability to change what a switch can do is critical as the needs of the computer network change. The unmanaged switch allows devices to talk to each other, but a managed switch features everything an unmanaged switch can do and more. It gives the user ability to configure, manage, and monitor the LAN, allowing for increased security, and more control over how and when data travels over the network. By protecting and enhancing the security protocols, the managed switch can stop intrusions. By controlling who can access the network in the increasingly secured network environment, managed switches use protocols such as the Simple Network Management Protocol (SNMP). This monitors all network devices, exchanging and managing information between them, and redirect if necessary. In older systems or ‘HUBS’ operated like walkie-talkies where only one person could talk at a time, muting all others on that line. Then, switches were developed to behave more like telephones where two or more people could talk, and others could hold separate and individual conversations; not interfering with the other. Switches allowed for simultaneous interactions and managed switches secure that data over the Ethernet. Considered, outdated and lacking security, Hubs are now replaced by switches. They are considered 'legacy' devices to be replaced by advanced managed switches that are modular and can automate more processes to speed up voice and data transfer. Each business needs to evaluate and assess the needs of their network at any given moment, and when network requirements evolve to where they need more input and control over the behavior of traffic on their LAN, then it is crucial to change to managed switches. Cable Supply offers solutions for the increasingly complex needs of sending information for data centers, for small and large businesses, and for more efficient operation of the network. For deploying advanced services such as wireless LANs or IP telephony in managed switches create the foundation for technologies, as more and more people expect them on demand. The real advantages to using managed switches include replacing legacy or older technologies like ‘HUBS.’ Cable Supply offers the best quality network switches and switching solutions, and offer cables and accessories that compliment any data center management.More Less
