Imagine if we were asked to perform computer network design in the office, campus or building a separate room with each other, and each room is already in use with furniture that can not be contested. Of course we will be thinking how to perform the complicated wiring installation in the room. However, it is not too complicated if we do the design using a wireless or WiFi network instead of cable. Certainly the use of Wifi networks contain consequences, including on each client computer must also be installed wifi devices. But all does not matter if it's an option. This paper will discuss the simple design of computer-based wifi network instead of wiring systems.
Wireless devices can work in several modes, among others:
1. AP mode (access point), this mode is often called multipoint. one wireless device can be accessed by many wireless devices.
2 Mode client, a client of the AP mode
3. Bridge mode, used for point to point two wireless devices. Usually used to reach wireless devices attached to long distances. In this mode if the network is very complex will result in an increased traffick broadcast.
On this occasion we will discuss the AP and client mode for the implementation of a computer with a wireless network (WLAN). Scheme are:
<-----> <-------> Internet Router Wireless Access Point Wireless <-------> PC Client With Client
Let us begin to mask the technical steps to setup a Wireless Access Point. In this example use Wireless AP / Client with Senao brand. For other brands pretty much the same process.
1. Prepare equipment including Wireless Radio, make sure all the complete adapter, crossover cable and others.
2. Configuring a PC with an IP address on the 192.168.1.0/24 network, do not use ip 192 .168.0.1 because this ip default Senao.
3.Browse http://192.168.1.1 via web browser, enter the username: admin, password blank.
Wireless Connection is now increasingly be needed. Various devices share of fans scrambling technology without cable connection. The principle is: practical, but still Digdaya.
One wireless technology that is now loved the Wi-Fi (wireless fidelity)-connections that could divide the high-speed Internet access without the mediation of the cable.
This wireless connection has just brought a projector manufacturer InFocus complementary capabilities newest products. With the addition of M1-DA port and M1-D on the projector that can be connected with Wi-Fi adapter called Infocus LiteShow, the projector can be connected with various devices wirelessly.
Deliver presentations from a computer, laptop, PDA, or any other handheld tools that enabled Wi-Fi becomes easier. Users do not have to bother with cable ropes as Wi-Fi coverage radius of 100 meters.
Wi-Fi is a technology that emits a radio signal with an Internet connection up to a certain radius. If this tiny device attached to the modem with a wide banded connections, all computers and devices that have Wi-Fi receiver in the vicinity would be splashed Internet access.
No matter the modem was in the office next door, room door, or the house across the street. Also, no matter whether the owner of the modem that allows its Internet access enjoyed by others without permission. This is a sophisticated method based on the idea of intelligent wild.
Behold: the technology standard 802.11b, aka Wi-Fi using the 2.4 GHz spectrum is capable of transmitting signals as strong as 11 megabits per second (Mbps). Not to mention the presence of two new standards, 802.11a and 802.11g, the more inviting admiration.
802.11a technology, which uses the 5 GHz spectrum, enabling transmission of up to 54 Mbps. While 802.11g, which only uses 2.4 GHz spectrum, capable of transferring data up to two-fold, 22 Mbps.
Therefore, in coffeehouses, restaurants, or airport lounges, you do not have to look for a phone connection just to get Internet access on your laptop.
With this technology, you do not need to be busy heaved a deep cord. Including when to use a projector for presentations, Wi-Fi can be a very kind-hearted gods.
The benefits of the internet that how can we get from these technological advances. The benefits of today's Internet seem increasingly play an important and very wide-ranging. When in about 10 years ago, the benefits of the Internet is more widely used by offices and business circles, is now arguably the Internet becomes mandatory for various community groups and the majority of young people terutama.Juga Internet access is now much easier in the can with a lot of bertebarannya cafe, many schools provide facilities and provide lessons about the internet world. Technological sophistication also smartphones, gadgets and internet access from rumahpun now be obtained easily and with relatively low cost. Internet as if such a door, that when we passed it, would stretch all sorts of things from around the world. Not limited to limitations of the eye could see, the internet offers to us to be able to travel the world without having to move from place to sit in front of the monitor screen. As if the Internet world without boundaries of space and distance. Through the internet we can get a lot of the latest information about various things. Met via the Internet with people from different parts of the world, sharing, talking, exchanging ideas, exchanging knowledge and will certainly benefit a lot more we can get the internet.The benefits are felt more and more internet for the users who can not escape from this internet world. Such as the internet marketing, blogger, bloggers, and online stores also now increasingly haveplace in the eyes of consumers who are looking for specific items. Consumers do not have to bother anymore to obtain an item. Can simply find additional information about the desired items at once or even ordering, paying and completing all transactions, and then just waiting for the goods delivered correspond to come we ask for the address.Can it be trusted, or is not afraid of the risk to be lied to when ordering goods over the internet? Of course, all possibilities can happen, let alone in the virtual world (read: internet), in the real world that also looks real goods, the seller and buyer can still occur even if these risks. Like most everything else in the world, the Internet also have two sidesdifferent. Black and white, good and bad, benefit and harm, positive and negative. Then exactly what benefits the internet that we can take, especially for young people. We start from the negative impact first.
