What is a rope?
Local network (LAN) consists of two or more computers connected together in a building or house using software and hardware. This is in contrast to the wide network (WAN), such as the Internet, which covers a large geographical area. There is a main computer or server and remote computers called clients . By creating this type of network in the home or office, computers can share files, sources and, if necessary, internet connection.
LAN can be one of two types: wired or wireless . The cable ropes require the Ethernet cable for physical connection of all computers in the network to the main device called switch . The wireless type uses radio waves to communicate, eliminating the need for wires. Therefore, the hardware used in the network should be either wireless or cable type.
LAN is quite easy to set. All Microsoft operating systems from Windows 98 Special Edition (SE) included built -in networkIng Software. When it comes to hardware, each computer requires a network interface card (nothing). The switch switch is also required. This is a device that resembles an external modem and controls network information. If LAN talks to another network like the Internet, the router is also required. Fortunately, you can buy an external DSL modem with a built -in switch and a router in a wireless or cable configuration.
Desktop computers usually use internal nothing that slip into the available slot on the motherboard, while the notebook can use a PC (PC) nothing. This type of nothing resembles a strong credit card that can be inserted into the PC card slot.
If the LAN is to be firmly connected, everyone must have nothing to connect the Ethernet cable Ethernet port. In the wireless LAN, everyone could have a small radio wave antenna. The server is heavy-weighted to the modemDSL, switching or router, while clients can communicate wirelessly if necessary. If it has no internet connection or any other network, the switch itself will be OK.
Once the local area network is set, the administrator can indicate which files and programs can be shared on it. Some server areas may be maintained behind the firewall to avoid access. All operations in the network, including e -mail, surf the Internet and other activities, the administrator can monitor using different tools.
The benefits of LAN in the office are diverse. For example, thanks to the central printer, the company can avoid buying individual printers for each workstation. The workflow is improved while it is easier than ever to control and serve. Flexibility and creativity can also improve. It is often a mutually advantageous situation for both management and employees.
LAN at home is extremely comfortable. Share programs, pictures, music and dig -upsTal and enjoy playing. Share a top color printer, scanner or other device. If you are worried about using the Internet of your children, this is one way to oversee online activity.
Hard-reinforced LAN is more difficult to install because it requires starting a physical ethernet cable from each client to DSL, switch or router. However, this type is reliable and safe. Wireless LAN is easier to install and cheaper, but requires a few more steps in the software settings to ensure that it is safe. It can also be slower than cable, but it depends on the wireless standard used, as newer standards effectively compete with Ethernet speed.
