Wired or Wireless network without (WiFi) in Indonesian called wireless, is a technology that connects two devices to exchange data without the cable media. Data exchanged through the medium of a particular wavelength of light (such as infrared technology on remote TV) or radio waves (such as bluetooth on the computer and mobile phone) with a certain frequency.

The advantages of this technology is to eliminate the use of wires, which can be quite disturbing the aesthetics, and also the complexity of installation to connect more than 2 devices simultaneously. For example: 1 computer to connect a server with 100 client computers, it takes a minimum of 100 pieces of cable, the length varies according to the distance from the client computer server. If kabel2 is not covered through a special lane (such as cable tray or conduit), it can interfere with the eye sight or interior of a building. This unpleasant sight does not exist on the relationship between devices in wireless technology.

Disadvantages of this technology is the possibility of interference of neighbor relations other wireless devices.

Type - the type of wireless:
WAP (Wireless Application Protocol)

Is a standard for wireless application protocol (as used in mobile phones). WAP is the result of collaboration between the industry to create an open standard (open standard). WAP is based on Internet standards, and some of the protocols that have been optimized for wireless environments, such as the need for data compression, long latency and bandwidth limitations, and the limitations of wireless devices. Design of information transmitted via WAP usually use format WML (Wireless Markup Language). WML is similar to HTML, just more specific to wireless devices that have limitations as above.

WBMP (Wireless Bitmap)

Format charts contained in WAP. WBMP is a similar format to BMP format. WBMP format images with the standard is divided into two parts, namely: q The header section, a place for the characteristics of image information, such as height, width and type of image. q The contents of the so-called Type dependent, is part of the image information.

WBMP format is the standard arrangement can be made with expanded its usefulness. Type part or content can be transformed into formats that can be accessed bare. Although WBMP will slow down the data transfer because the size is not small, but using images can provide more information on a small screen like the handhone.

Wireless LAN (Wireless Local Area Network)

Data communication technology by not using a cable to connect between the client and the server. Wireless LAN technology is generally similar to computer networking technology that uses cable (Wire LAN or Local Area Network). Wireless LAN technology is using radio frequencies to transmit and receive data that would reduce the need for or dependency relationship through cable. As a result, users have a high mobility or flexibility and does not depend on a place or location. Wireless LAN technology also makes it possible to establish a computer network may not be accessible by a computer network that uses cables.
