When you use a computer to access the web, you are using an internet browser that requires network devices to function properly. There is a common misconception that networks are merely computers and wiring. In reality, web accessibility requires highly-specialized hardware. Below, our IT support professionals in West Palm Beach shed light on network devices and how they work.
Networking Explained
Home networks, small office networks and even comparably large networks can be broken down into smaller pieces. Such smaller segments are distinguished from the overarching network by a device that filters data and ramps up network efficiency. Such web traffic filtering devices are referred to as connectivity devices. Routers, switches, hubs and bridges all qualify as different types of connectivity devices. These connectivity devices work with one another to control traffic through the filtering and isolation of information. These devices also connect various types of networks through the network protocols. Connectivity devices also serve the purpose of hierarchical addressing. The network is segmented through such connectivity devices to transmit data to the proper destination by way of the network ID/host ID of the IP address.
Hubs
Hubs are connectivity devices that network cables connect to to create a network segment. Hubs re-send incoming packets of data rather than filtering such data. Just about every modern-day network relies on a central hub to allow computers to connect on the network. Computers connect to the hub by way of a single line in a hubbed network to simplify the addition or removal of a host to the network.
Bridges
Bridges are connectivity devices that transmit data based on an address. In the context of networking, bridges filter and forward packets of information in accordance with physical addresses. Bridges function at the TCP/IP protocol stacks Network Access Layer.
Routers
Routers are a key component of the overarching TCP/IP network. This connectivity device forwards data after filtering it. This device uses IP addresses in the context of TCP/IP networks. Routers are essential for traffic control and maintaining network efficiency. If you have any problems with your router, our IT support team in West Palm Beach can help.
Switches
Switches understand the addresses tied to each individual port and forward incoming information to the proper port. Switches make decisions regarding forwarding based on guidelines from TCP/IP protocol headers. It is best to think of switches as intelligent hubs. Every computer is connected by way of one line just as occurs with hubs. The difference is the switch is more intelligent about the transmission of data that arrives by way of one of the ports.
Network devices will become even more essential to conducting business as we segue into a future in which technology is ubiquitous.
