Sejarah Perkembangan Jaringan Komputer

Perkembangan jaringan komputer tidak dapat dipisahkan dari perkembangan teknologi komputer. Pada generasi awal komputer, para pemakai atau user secara paralel melakukan akses ke komputer menggunakan terminal yang dihubungkan melalui suatu media transmisi tertentu. Terminal sebenarnya hanya merupakan alat Input dan Output saja (Keyboard dan Monitor) sehingga sering disebut Dumb Terminal karena tidak
memiliki kemampuan memproses (Processor).
Dengan adanya perkembangan teknologi perangkat keras yang sangat pesat, maka datanglah generasi baru dari komputer yang dikenal denagn Personal Computer. Dengan relatif murahnya harga komputer maka di berbagai lingkungan kerja dapat kita temukan banyak komputer dipakai sebagai alat untuk membantu melaksanakan berbagai pekerjaan. Keadaan tersebut menimbulkan permasalahan baru, yaitu efisiensi dan
efektifitas pemakaian perangkat tambahan komputer.
Selain itu permasalahan lainnya pun akan timbul seperti dalam hal tukar menukar data atau file. Dengan adanya problem tersebut timbulah ide untuk menghubungkan kesemua komputer sehingga membentuk suatu jaringan komputer. Sehingga dapat disimpulkan bahwa Jaringan Komputer adalah:
"Suatu sistem yang terdiri dari 2 komputer atau lebih yang dihubungkan melalui suatu media komunikasi beserta perangkat (device) tambahan lainnya.
Setelah terjangkaunya harga komputer mikro dan konsep proses distribusi sudah matang, maka penggunaan komputer dan jaringannya sidah mulai beragam dari mulai menangani proses bersama atau komunikasi antar komputer (Peer to Peer System) tanpa melalui komputer pusat. Setelah itu berkembang teknologi jaringan lokal yang kita sebut LAN (Local Area Network). Demikian juga ketika Internet berkembang, maka sebagian besar LAN yang berdiri sendiri mulai terhubung & terbentuk jaringan raksasa yang disebut dengan WAN (Wide Area Network).
Jaringan Komputer dapat di klasifikasikan menjadi beberapa bagian, yaitu:
1. Jaringan Komputer Berdasarkan Cakupan Luas:
# LAN (Local Area Network)
Yaitu jaringan dengan area terbatas seperti di dalam gedung atau beberapa gedung yang berdekatan. LAN memiliki 3 perbedaan karakteristik dari jenis jaringan lain, yaitu: ukuran, teknologi transmisi, dan topologinya.
# MAN (Metropolitan Area Network)
Merupakan LAN yang memilki ukuran yang lebih besar,akan tetapi memakai teknologi yang sama dengan LAN. MAN juga dapat dimanfaatkan untuk keperluan umum ataupun privat, MAN menunjang komunikasi data, suara dan dapat melakukan koneksi dengan jaringan TV Kabel.
# WAN (Wide Area Network)
WAN mencakup area geografis yang luas, misal: sebuah negara atau benua, dengan beragam fasilitas komunikasi seperti transmisi satelit, sistem radio permukaaam, kabel bawah laut, dll.
2. Jaringan Komputer Berdasarkan Kecepatan:
# Low Speed Network
# Medium Speed Network
# High Speed Network
# Super High Speed Network
3. Jaringan Komputer Berdasarkan Teknologi Transmisi:
# Jaringan Broadcast
Memiliki saluran komunikasi tunggal yang dipakai bersama oleh semua mesin yang ada pada jaringan dan memungkinkan pengiriman suatu paket (pesan berukuran kecil) ke semua tujuan.
# Jaringan Point to point
Terdiri dari beberapa koneksi pasangan individu dari mesin. Untuk sampai ke tujuan suatu paket harus melalui satu atau lebih mesin perantara, atau melalui banyak route yang berbeda jaraknya sehingga algoritma routing memegang peranan penmting pada jaringan ini.

From there my am same near by starts of Lutfi, Nia and Zuli. I love to can pal up with them, because I thus has return friend coincidently our house are concurrent. Although at that moment my friend Lutfi is having an affair with its the gank friend, be Tita and Vini. I also tries to pacify them and simply effort for me produces fruit result, Lutfi, Tita and Vini also returns to making friends. I love to see it although in my heart there are a few having cold feet thrown but simply my am wrong, they invite I to join together they. However I refuse it smoothly because for me makes friends that with whom just during we able to differentiate good which and which old.

Interlude

Possibly posting now rather is rather differed in the solution with posting yesterday, at first I planned to make this continued posting but because of I forget story canal posting yesterday, then now I will tell about my life with my friends.
For me friend is man which able to make our more having colour life. Honestly I actually non type man which able to easily receives presence of novice in my life. I of course recognizes many people but to make them as my friend that is not easy thing me to. Because for me friend is man which able to understand us, but I also consciousness to be able to recognize character or someone character requires old time. Possibly that making I am not easily receives presence of others in my life as my friend.
Because now looks for friend which able to understand and receives lacking of we are not thing which is easy, we also is claimed to be able to understand him or her. Friend we doesn't become create enemy ourselves.

My Emosion

This Posting was continuation from posting yesterday and possibly will joint finite of last posting.
Life of course always full of mystery which we have never understood and we to suspect, and life also full of choice that is sometimes makes we are difficult in taking decision. But I also believe if in every sure problem there are wisdom and mean. I also knew existence of this problem diffraction make me is more adult, more patient, wiser, warier in acting and talking, and it is of course make stronger me experiences this life. Although sometimes at the time of the problem at in my life, difficult for me to be able to finalize the problem adultly wise and.
Sometime I think why people love to jeer lacking of others, though if they are in position of like that they will surely fulminate and or for they stubborn will try forgives but I to know in the heart they disappointed. Though the infinite creates man as august is being, meaning if like that we to affront creation is being of the infinite

Preparing for group presentation

aWhether you’re introducing a new company to investors or updating management on an important project, a well-planned presentation will make you look good. Presenting as a group is challenging. Here are some guidelines for planning and presenting as a team.

· Develop outlines. For each section of the presentation, identify key points to make

· Focus on clarity. In general simple is better.

· Plan your time well. Allow enough time for each speaker and for questions at the end.

· Put background information or data on a separate handout. This will help listeners focus on your key points.

· Remember your listener’s needs. How long will people be sitting? You may decide to stop and take a break in the presentation at a mid-point.

· Use visuals. Visual add variety to a presentation. But don’t use too many, and avoid turning down the lights for too long, especially after lunch.

· Practice the presentation as a team several times. Each member needs to be familiar with everyone else’s content. Pay attention to transition points. For example, how will a presenter introduce the next speaker.

· Plan to arrive early and check your equipment. Make sure that video screens and projectors are well-placed,plugged in, and working
