What is a rope network?
Local network (LAN) connects computers in relatively close proximity to share files, printers, other sources and online access. LANs are used at home and in business and can either be connected or wireless. Given the ubiquitous use of shortcuts that have become virtual words, many use the term "ropes", even if it is redundant. Connecting the "network" to the shortcut can remind people of the new network networks, what the shortcut refers to. This article will use the term and at the same time records for the reader that the correct use is LAN. The high -speed internet account can also be shared on LAN to provide online access to all computers connected to the network. So how does LAN work?
In network architecture, one main computer is marked as a server and all other computers are called clients. The server and clients must all be connected to an external hub, what kind of box that acts as a crossroads. Now that computers have a crossroads to go through they needTraffic cop for operation routing. Each hub contains a so -called router.
In order to direct the operation through the LAN network, each computer must have a unique address on the network. This unique address comes with a network card, commonly installed inside each computer. The network card not only adds a unique address, but also uses a language or a protocol to interview a hub/router. The hub/router and network card cards must speak the same language or be compatible with the same network protocol or standard for functioning.
with a more applied hub/router and all network cards installed is a LAN network ready for configuration for use to share files or resources. If online access is required, the charge/routerb must be connected to the high -speed modem. Alternatively, you can buy a high -speed modem with a built -in horn and router.
networkLAN can be connected or wireless. If you set the cable network, all computers must be connected to a hub/router using Ethernet Cabeling. This can be expensive if the cabling must be driven through walls or ceilings. An alternative is the wireless ropes that communicate through radio waves.
Before purchasing network devices, you must decide whether the LAN will be connected or wireless. Cable network cards have an Ethernet port for cabling, while wireless network cards and hubs/routers contain radio for sending and receiving radio transmissions.
If the LAN is to be wireless, it will work using a set of standards known as IEEE 802.11. There are different flavors within the 802.11 standards, with the latest 8.11n. This standard replaces the older 802.11g standard, with 802.11n faster and broadcasts to a wider range.
It is the wisest to create a wireless LAN network using the latest standard for future evidence of the investment. Since spring 2009 tO means that all network devices should be compatible with 802.11n. A network card or router that only supports the older 802.11g standard will not operate in the 802.11n network, if the HUB/router does not support 802.11g and 802.11n.
Packing or specifications of wireless network devices should clearly indicate which protocols are supported. Some devices have Wi-Fi® certified by Wi-Fi Alliance, an organization responsible for supervision of wireless standards. It is guaranteed that these products are fully satisfactory and have undergone testing. Products that be certified will still indicate which protocols support and may be cheaper because the certification process increases the cost of the product. If the Setup LAN settings, certified network devices may be more desirable.
