Pengenalan Jaringan Merupakan sebuah sistem yang terdiri atas komputer,

perangkat komputer tambahan dan perangkatjaringan lainnya yang saling terhubung denganmenggunakan media tertentu dengan aturan yangsudah ditetapkan

Kebutuhan untuk terhubung ke jaringan danmemanfaatkan layanan yang ada : Koneksi Secara Fisik (Phisical Connection), secara

langsung peralatan harus terhubung dengan jaringantersebut.

Koneksi Secara Logis (Logical Connection), harus adaaturan yang sama supaya semua peralatan bisasaling berhubungan.

Koneksi Secara Fisik Semua peralatan yang

berpartisipasi harus terhubungsecara langsung.

Peralatan yang dibutuhkanuntuk koneksi secara Fisik: PC NIC Network Media Repeater/Hub/Bridge/Switch

/Router

Koneksi Secara Logis Merupakan sebuah aturan bersama bagaimana

informasi dikirim melalui media. Biasa disebut dengan protokol Jaringan pada dasarnya gabungan dari berbagai

macam protokol yang muaranya adalah bagaimanainformasi yang dikirim oleh pengirim bisa diterimaoleh penerima dengan benar.

Yang termasuk dalam protokol : Bagaimana format data yang dikirim ? Bagaimana cara data dikirim ? Bagaimana jika terjadi kesalahan selama pengiriman

dan apa yang harus dikerjakan ?

Akan dibicarakan pada kesempatan lain

Attenuation and insertion losson copper media

Attenuation is the decrease in signal amplitudeover the length of a link.

Long cable lengths and high signal frequenciescontribute to greater signal attenuation.

Sources of noise on coppermedia

Crosstalk involves the transmission of signals from one wire to anearby wire.

When voltages change on a wire, electromagnetic energy is generated. This energy radiates outward from the transmitting wire like a radio

signal from a transmitter. Adjacent wires in the cable act like antennas, receiving the transmitted

energy, which interferes with data on those wires.
