Bagaimana cara kerja jaringan nirkabel?

Bagaimana cara kerja jaringan nirkabel? - Jaringan nirkabel bekerja menggunakan gelombang radio daripada kabel untuk mengirim data antara komputer. Ini adalah versi sederhana. Jika Anda ingin tahu apa yang terjadi secara lebih rinci, maka ini semua dijelaskan dalam artikel ini.

Bagaimana cara kerja jaringan nirkabel

Dan angka nol.

Aplikasi Kamera Tembus Pandang Saya yakin Anda tahu bahwa komputer mengirimkan data digital, menggunakan biner: dan angka nol. Ini adalah cara berkomunikasi yang diterjemahkan dengan baik ke gelombang radio, karena komputer dapat mengirimkan orang dan nol sebagai jenis bip. Bunyi ini begitu cepat bahwa mereka berada di luar jangkauan pendengaran manusia--gelombang radio yang tidak bisa mendengar adalah, pada kenyataannya, di sekitar Anda sepanjang waktu. Itu tidak menghentikan komputer dari menggunakan mereka, meskipun.

Kode Morse.

Cara kerjanya adalah banyak seperti kode Morse. Anda mungkin sudah tahu bahwa kode Morse adalah cara yang mewakili alfabet sehingga dapat ditularkan melalui radio yang menggunakan titik (bip) dan sejumput (panjang dash). Itu digunakan secara manual selama bertahun-tahun, dan menjadi cara yang bagus untuk mendapatkan informasi dari satu tempat ke yang lain dengan penemuan telegraph. Lebih penting lagi untuk contoh ini, meskipun, itu adalah sistem biner, sama seperti komputer dan angka nol.

Anda mungkin berpikir nirkabel jaringan, kemudian, sebagai kode Morse untuk komputer. Anda pasang gabungan radio penerima dan pemancar di, dan komputer mampu mengirimkan setara titik dan tanda hubung (bit, di komputer-berbicara) untuk mendapatkan data Anda dari satu tempat ke yang lain.

Semua tentang frekuensi.

Anda mungkin bertanya-tanya, meskipun, bagaimana komputer mungkin bisa mengirimkan bit cukup untuk mengirim dan menerima data dengan kecepatan itu. Setelah semua, harus ada batas pada berapa banyak dapat dikirim dalam sesaat sebelum itu hanya menjadi omong-kosong tidak berguna, kanan? Well, ya, tapi kunci jaringan nirkabel adalah bahwa hal itu akan di sekitar masalah ini.

Pertama-tama transmisi nirkabel yang dikirim pada frekuensi sangat tinggi, artinya bahwa lebih banyak data dapat dikirim per detik. Koneksi nirkabel sebagian menggunakan frekuensi 2,4 gigahertz (2,4 milyar siklus per detik)--frekuensi yang serupa untuk ponsel dan microwave oven. Seperti yang mungkin Anda ketahui, meskipun, frekuensi tinggi ini berarti bahwa gelombang harus sangat pendek, itulah sebabnya nirkabel jaringan hanya bekerja di wilayah yang terbatas.

Selain itu, membuat jaringan nirkabel menggunakan teknik yang dikenal sebagai 'frequency hopping'. Mereka menggunakan puluhan frekuensi dalam kisaran mereka diberikan, dan terus-menerus beralih di antara mereka. Hal ini membuat jaringan nirkabel lebih kebal terhadap gangguan dari sinyal radio lain daripada mereka akan jika mereka hanya ditularkan pada satu frekuensi.

Akses poin.

Langkah terakhir adalah ketika datang ke semua komputer pada jaringan berbagi akses Internet. Hal ini dilakukan menggunakan sepotong khusus peralatan nirkabel disebut jalur akses. Akses poin lebih mahal daripada kartu nirkabel untuk satu komputer, karena mengandung radio yang mampu berbicara dengan sekitar 100 komputer pada waktu yang sama, dan berbagi keluar akses Internet antara mereka. Akses khusus hanya benar-benar penting bagi jaringan yang lebih besar, meskipun--jika Anda hanya memiliki beberapa komputer, mungkin untuk menggunakan salah satu dari mereka sebagai titik akses, atau Anda bisa mendapatkan router nirkabel.

Mereka mengerti satu sama lain.

Itu semua baik dan bagus, kemudian, tapi bagaimana peralatan nirkabel yang dibuat oleh perusahaan yang sama sekali berbeda mengelola bekerja bersama-sama ketika ini semua begitu rumit? Well, jawabannya adalah bahwa ada standar yang mengikuti semua perangkat nirkabel. Standar ini secara teknis disebut standar 802.11, dan ditetapkan oleh IEEE (Institute of Electrical and Electronics Engineers). Ini adalah berkat orang-orang yang menempel standar mereka jaringan nirkabel begitu mudah dan murah untuk menggunakan hari ini.

Anda tidak perlu khawatir.

Jika semua ini berbicara frekuensi telah Anda sedikit khawatir, Anda tidak perlu menjadi--nirkabel jaringan hardware dan software menangani semua ini secara otomatis, tanpa Anda perlu melakukan hal. Jangan berpikir bahwa Anda akan harus memberitahu satu nirkabel perangkat apa frekuensi yang lain menggunakan, karena itu hanya tidak akan terjadi, baik-baik saja? Nirkabel jaringan, untuk semua kerja rumit, benar-benar jauh lebih mudah digunakan daripada yang pernah Anda harapkan.

Dominican Republic Holidays – The Cocolo Festival

Like the entire Dominican Republic celebrate the opening from the New Year on January 1st, some Dominicans hold events that give importance to perhaps one of the dying yet very prominent traditions inside the land inside a feast known as Cocolo Festival. 

Once the wave of African immigrants moved into Hispaniola during and once the Spaniards have settled inside the land, they‘ve brought many traditions with these that now compose the fibers from the Dominicans' culture. Among the many groups of ethnic immigrants was the Cocolo tribe which originated coming from the Bahamas and also the Greater Antilles. They‘re largely referred to as English-speaking Caribbean people that brought with these a culture that has got the elements of both the European and African cultures. It‘s, as so many have said before, the culmination from the merging from the cultures from the African slaves and also the European colonizers. Although they still have retained their political and social economic authority. 

Years after they‘ve settled in Hispaniola, the Cocolo dancing drama tradition have developed. It was eventually, among their very own educational system and religion, the foremost distinct expressions of the culture. It was eventually its peak throughout the mid-nineteenth century. In recent times, the assimilation from the Cocolo descendants using the majority from the Dominicans have caused the disintegration from the Cocolo's culture. Although, as is apparent in certain areas inside the Dominican Republic, the Cocolo dancing drama tradition remains greatly alive. 

In its original form, the dancing drama is performed on Christmas as well as on Carnavals. Nowadays, It‘s performed only in January in San Pedro de Macoris, a province inside the Dominican Republic in which the Cocolos originally settled. 

The Cocolo Festival features the music, dances and songs which are patterned inside the tunes of the initial Cocolo music. These have African and European influences which get them to very unique inside the Dominican Republic, otherwise distinct from several music in the planet. 

The music, for instance, is patterned following the African pace and also the dances possess the steps and movements particular towards the African court. Although when these are generally dramatized, they become an entirely different art form. They become almost exclusively European due to the themes and stories adopted. Among the foremost typical stories performed inside the Cocolo Festival is that the Mumme's Play, thus the Festival has grown to be related to street dancers and performers known as 'Mummers'. This tells from the story about St. George and his enemy. In summary, this reflects the most theme from the Cocolo dance drama – the battle between good and evil. 

Other dance dramas and games usually performed in the Cocolo Festival will be the 'Guloyas' and also the 'Baile del Buey'.

Dominican Republic Holidays – The Christmas Day

Being predominantly Catholic, Christmas day takes a really special place inside the Dominican Republic's holidays. Sure, there aren‘t any white Christmases or Christmas balls, but Dominicans have their special method of celebrating the centerpiece of Christian holidays inside the Caribbean.

However the Christmas mood begins far sooner than that. Beginning on the very first day‘s December, the Dominicans start playing traditional melodic Christmas tunes. Usually, groups of 2 to 4 persons play the official Dominican music, the Merengue, using the accordion, the drum and also the güira towards the tunes of Christmas carols, which depart anticipation to the celebrations to come. 

The sense of community is extremely strong among Dominicans. This really is why it isn‘t surprising that informal Christmas parties, known as Aguinaldos, parties which are open for everybody and never only for a couple of relations are held through the entire nation. People could derive from anywhere, whether or not they are invited or otherwise. On most cases, people that participate inside the Aguinaldos will be the singing parties who, on the method to the Christmas party, have visited numerous houses where they had been either given a home-made ginger beverage known as 'jengibre' or perhaps a taste of what‘s served upon the dinner table from the family they‘ve visited, called 'bocadita'. 

And in fact, once all of us have gathered inside a house in which the party is placed to kick off, partying, dancing, eating, and drinking begins. Beginning with traditional Dominican Republic carols, this party continues well into midnight. 

The Aguinaldos have always been the typical Dominican Republic method of celebrating Christmas. These informal community parties are enjoyed in the foremost populated areas from the country in which the sense of community is extremely strong. 

Because a lot of the people inside the Dominican Republic are mostly poor or middle class, the way in which Christmas is celebrated varies. It is crucial though for each Dominican family to become together on Christmas eve and Christmas day. Both are official non-working holidays. 

What could be Christmas if there aren‘t any Christmas decorations? 

The Dominicans have a really distinct method of decorating their homes during Christmas. Most families have recreations from the Nativity as well as Birth of Jesus Christ inside their homes. These are generally called 'Nacimiento'. 'Charamico', the Dominican Republic's version from the Christmas tree, is that the literal translation of 'dry branch'. To function a Christmas tree, the 'Charamico' is painted white and decorated with typical Christmas tree decors like balls, lights, and ribbons. 

Dominicans even have their very own special version from the European flower for Christmas called Poinsettia, which they call, 'Flor de Pascua'. Most homes also grow the 'Estrella de Natividad', literally translated like the 'Star from the Birth' of Christ. 

Truly, Dominican Republic has very special ways of celebrating the festive season of Christmas.
