A small home-based business or rental space, then it can be very profitable, can be provided in the same style in a large scale company office. Using standard size of desktop computers in this configuration is impossible, because it takes too much space and too large for the limits on overcrowding. To address this situation, or transportable May desknotes enough to hold the key.
Desknotes are systems that can be used alternately as a standard desktop PC, but also provides portability on the market. Desknotes have the same power levels of a desktop PC and occupy much less space. In addition, to keep costs to a minimum, it is possible to install a local network between desknotes when only a laptop must be connected to the Internet and shared access to all computers connected to the mobile network. This also applies to devices connected to the mainframe, LAN, all computers can use the same portable device. Therefore, for small offices with more than three laptops, LAN (Local Area Network) is certainly an asset.
LANs normally cover a building or a small group of buildings. Connect a LAN with many others through telephone lines and radio waves is called WAN (Wide Area Network). A local network that uses radio waves to communicate is called WLAN (Wireless Area Network). There are several advantages to WLANs. The first is its flexibility. Radio waves can pass through the walls of almost any surface, and do not require miles and miles of cables, offering a clutter-free work atmosphere. Wireless LAN can be almost invisible!
Another advantage is that WLANs are extremely easy to use. Most laptops are built with WLAN capability. Therefore, all you have to do is connect and make sure you have a wireless LAN card. WLAN is very difficult. If a database is offline, you can use another laptop and can be physically moved from base to the range of another WLAN. The prices are very low these days for wireless networks, and it is not surprising that the choice for home networks.
However, since nothing is perfect in this world, WLAN does not take a few drawbacks. Anyone can operate a laptop near a wireless network and is stored in the hacking wireless traffic. This is a security problem due to loss of privacy. While radio waves can pass through almost any surface, too many obstacles such as buildings can degrade the transmission. Another drawback is the speed of data transfer. Like many laptops share the same bandwidth, data transfer speed is much lower in a WLAN. Furthermore, the rate of wireless data in the fall, depending on signal strength or interference.
Wireless LAN is desirable that the mobility is necessary, and is the only option in older buildings where cables can not be installed. Companies often provide fixed wireline connections offices, and wireless LAN for users who have no fixed location. Ultimately, WLAN should be installed only after taking into account all factors in your office or home created.
