Ethernet Kart\u0131 Nedir?<\/h2>\n

Ethernet kart\u0131, a\u011f ve bilgisayar\u0131n ileti\u015fim kurmas\u0131n\u0131 sa\u011flayan, anakarta tak\u0131lan fiziksel bir a\u011f arabirimi. Ethernet kart\u0131 kullan\u0131larak, bilgisayar a\u011flar\u0131nda yer alan farkl\u0131 bilgisayarla veri transferi ger\u00e7ekle\u015fir. Ethernet kartlar\u0131n\u0131n \u00e7\u0131k\u0131\u015f\u0131nda bulunan ba\u011flant\u0131 noktas\u0131na kablo ba\u011flan\u0131r. \u0130letilmesi istenen verilerin kablo yard\u0131m\u0131yla di\u011fer bilgisayarlara ula\u015fmas\u0131 sa\u011flan\u0131r.<\/p>\n

Ethernet Kart\u0131 Nas\u0131l \u00c7al\u0131\u015f\u0131r?<\/h2>\n

Ethernet kartlar\u0131 temel olarak anakart slotlar\u0131na ba\u011flant\u0131s\u0131 do\u011fru olarak yap\u0131ld\u0131ktan sonra herhangi bir yaz\u0131l\u0131ma gerek kalmadan \u00e7al\u0131\u015ft\u0131r\u0131labilir. Ethernet kart\u0131 transfer edilecek bilgiyi paketlere b\u00f6ler ve kart \u00e7\u0131k\u0131\u015f\u0131nda bulunan a\u011f kablosuna iletir. Bir yerel a\u011f (lan) sisteminde transfer edilecek bilgi paketlerinde, al\u0131c\u0131n\u0131n ve g\u00f6ndericinin MAC adresleri, ayn\u0131 zamanda iletilen bilgi ve CRC kodu bulunur. CRC kodu, g\u00f6nderilen bu bilginin bozulup bozulmad\u0131\u011f\u0131n\u0131n kontrol\u00fcn\u00fc sa\u011flar. Daha sonra paketlenen bilgi di\u011fer kullan\u0131c\u0131n\u0131n bilgisayar\u0131na ula\u015f\u0131r ve Ethernet kart\u0131 taraf\u0131ndan al\u0131n\u0131p \u00e7\u00f6z\u00fclerek, CRC koduna bak\u0131l\u0131r. CRC kodu ayn\u0131 ise bilgi kabul edilir. Paketten bilgi al\u0131n\u0131r ve bilgisayar taraf\u0131ndan i\u015flenir. CRC ayn\u0131 de\u011filse, bilginin bozulmu\u015f oldu\u011fu anla\u015f\u0131l\u0131r.<\/p>\n

Ethernet (A\u011f) Kart\u0131n\u0131n Yap\u0131s\u0131 Nas\u0131ld\u0131r?<\/h2>\n

Media Access Kontrol (MAC) Address: Mac adresi olarak bilinen ve her Ethernet kart\u0131n\u0131n kendine ait 48 bitten olu\u015fan bir numaras\u0131 vard\u0131r.\u00a0 Kart\u0131n rom belle\u011fine \u00fcretim s\u00fcrecinde kaydedilen bu numara de\u011fi\u015ftirilemez. MAC adresleri, bilgisayar a\u011flar\u0131nda veri ak\u0131\u015f\u0131 i\u00e7in kullan\u0131l\u0131r ve ayn\u0131 zamanda Ethernet kartlar\u0131n\u0131n birbirlerinden ay\u0131rt edilmesini sa\u011flar.<\/p>\n

CSMA (Carrier Sense Multiple Access): Ethernet a\u011flar\u0131ndaki ileti\u015fim an\u0131nda, belli bir anda a\u011f kablosunu hangi bilgisayar\u0131n kullanaca\u011f\u0131n\u0131 belirleyen CSMA y\u00f6ntemidir. Veri paketi g\u00f6nderilmeden \u00f6nce kablo kontrol edilerek transfer i\u00e7in izin verilir.<\/p>\n

Ba\u011flant\u0131 Portu: Ethernet kart\u0131 ve kablo aras\u0131ndaki veri transferini sa\u011flar.<\/p>\n

CRC Hata Kontrol\u00fc: Bir a\u011f i\u00e7erisinde iki farkl\u0131 bilgisayar birbirlerine veri transferi yapmak isterlerse, bunlar \u00e7er\u00e7eve (frame) denilen veri paketleri haline gelirler. CRC kodu ise bilgisayar\u0131n veri transferinde baz\u0131 hesaplamalar yaparak bir kod \u00fcretmesi ve bu kodu verinin sonuna eklemesidir. CRC kodu e\u015fle\u015fiyorsa, veri transferi do\u011fru bir \u015fekilde ger\u00e7ekle\u015fmi\u015ftir.<\/p>\n

Ethernet Kart\u0131 \u00c7e\u015fitleri Nelerdir?<\/h2>\n

Ethernet kart\u0131 \u00e7e\u015fitleri konekt\u00f6r yap\u0131lar\u0131na ve veri iletim h\u0131zlar\u0131na g\u00f6re olmak \u00fczere 2\u2019ye ayr\u0131l\u0131r.<\/p>\n

Konekt\u00f6r Yap\u0131lar\u0131na G\u00f6re Ethernet Kart\u0131 \u00c7e\u015fitleri<\/h3>\n

RJ-45 Konekt\u00f6rl\u00fc Ethernet Kartlar\u0131: 10, 100 veya 1000 Mbps<\/a> h\u0131zlar\u0131na kadar yeterli performans sa\u011flayan RJ-45 Konekt\u00f6rl\u00fc Ethernet kartlar\u0131, \u00e7ift b\u00fck\u00fcml\u00fc kablo ile kullan\u0131l\u0131r.<\/p>\n

BNC Konekt\u00f6rl\u00fc Ethernet Kartlar\u0131: Genellikle kablo ile kullan\u0131lan Ethernet kart\u0131 \u00e7e\u015fitleridir. BNC kontekt\u00f6r\u00fc kablonun ucuna tak\u0131l\u0131r ve 10 Mbps h\u0131z aktar\u0131m\u0131 sa\u011flar.<\/p>\n

Veri \u0130letim H\u0131zlar\u0131na G\u00f6re Ethernet Kartlar\u0131<\/h3>\n

10, 100 veya 1000 Mbps h\u0131zlar\u0131na sahip olan Ethernet kartlar\u0131d\u0131r. Evlerde ve i\u015fletmelerde ihtiyaca uygun olarak kullan\u0131lmaktad\u0131r.<\/p>\n

Ethernet kartlar\u0131, kablosuz ba\u011flant\u0131lara g\u00f6re daha tutarl\u0131 ve h\u0131zl\u0131 ba\u011flant\u0131 sa\u011flar. Bu sebeple, masa\u00fcst\u00fc bilgisayar modellerinde kullan\u0131lmaya devam ediliyor. Tabletler, diz\u00fcst\u00fc bilgisayarlar ve mobil cihazlar Ethernet yerine Wi-Fi kullan\u0131m\u0131na y\u00f6neldi. G\u00fcn\u00fcm\u00fczde okullarda, \u015firketlerde ve farkl\u0131 i\u015fletmelerde Wi-Fi kullan\u0131m\u0131n\u0131n artmas\u0131na ba\u011fl\u0131 olarak Ethernet ba\u011flant\u0131lar\u0131 azalmaya ba\u015flad\u0131. Ethernet ba\u011flant\u0131s\u0131na olan ihtiyac\u0131n azalmas\u0131, Ethernet kartlar\u0131na olan talebi de azaltt\u0131.<\/p>\n","protected":false},"excerpt":{"rendered":"
