Tapi anda (terutama yang cewe) kalo ditanyain kalimat di bawah ini pasti bakalan ga bisa jawabnya:
LO TAU GAK SEEEH APAAN ITU WIFI???
Don’t worry, supaya anda gak katrok2 amat, I will explain it for ya…
WIFI short for “Wireless Fidelity”, Wireless= tanpa kabel, Fidelity= kesetiaan, in conclusion= kesetiaan tanpa kabel… koq ga nyambung yah??? Udah daripada bingung kita bahas aja sejarahnya…
WIFI is a kind of “connection” that connected one computer to others, or to a server (usually internet server), which established a “wireless” connection that makes you freely moving everywhere while you are being connected to a server or other computers, with WIFI you can browsing on the internet (If you connected with an internet server), exchange data with other computer, playing games together (known as local area network gaming), or maybe international gaming (known as online gaming).
Dengan WIFI, anda terkoneksi ke dalam suatu jaringan (bisa jaringan internet atau jaringan local) dan bergerak sepuasnya tanpa kabel asalkan masi dalam jarak jangkauan radiasi sinyal WIFI.
TRUZ, SEJARAHNYA GIMANA??
IBM, a well-known computer manufacturer was the first inventor of this kind of connection. Their engineers managed to discover a substitution of outdated conventional “wired local area connection” which is limiting people movements, you couldn’t move freely with a wire attached to your computer.
They succeeded to introduce it, and on the other hand the worldwide consumers warmly welcomed it, just five year after its first introduction, WIFI became a standard of local connection, replaced “wired local area connection”.
SO, HOW DOES IT WORK??
It is very simple, just like our mobile phone that connected to a service provider. WIFI needs one server called “Wireless Network Router”, this server act as manager of all computer that connected to this device, this router broadcast a ultra high radio-wave signal to all direction from “ground zero”. This router could reaches for about 300 meters until 2 kilometers depend upon the condition (indoor or outdoor), settings and quality of the router itself. Every laptops, PDAs, or Computers which has already equipped with WIFI adapter within the range could send “a request” to the server for being connected to the wireless network. Once a “request” accepted, you can freely browsing to the internet (If the provider serves it), connected to other computers, chatting, etc.
Sebenarnya IBM membuat sistem ini untuk memudahkan perusahaan2 untuk membuat jaringan di kantornya masing masing tanpa kabel, tetapi pada perkembangannya, WIFI malah digunakan untuk menyediakan layanan internet gratis pada fasilitas2 umum di seluruh dunia, sungguh cita2 yang disalahgunakan (tapi cukup bermanfaat).
WIFI DAN KESEHATAN.
Sebenarnya belum ada studi yang menyatakan bahwa sinyal radio WIFI berbahaya bagi kesehatan manusia, tapi sekali lagi saya menekankan bahwa WIFI tetaplah sinyal radio seperti sinyal radio handphone, spektrum gelombangnya mampu untuk merubah susunan protein di dalam tubuh maupun otak menjadi mengeras bahkan rusak (silahkan baca posting terdahulu saya tentang MASAK TELUR PAKE HANDPHONE???). Gunakanlah teknologi dengan benar dan bijak agar tidak menjadi bumerang bagi kita sendiri...
