Packet switching breaks data into small packets that can travel across a network separately and reassemble at the destination.

Why it matters

The idea in context

Older communication imagined a dedicated circuit, like holding a line open from end to end. Packet switching made communication more like sending many labelled pieces through a changing city of routes. That flexibility became one of the deep ideas behind the internet.

Türkçe

Aynı kart, başka bir dilde.

Paket anahtarlama, veriyi küçük parçalara böler; paketler ağda ayrı ayrı ilerler ve varış noktasında yeniden birleşir.

Eski iletişim mantığı çoğu zaman iki uç arasında ayrılmış tek bir hat düşünürdü. Paket anahtarlama ise mesajı etiketlenmiş parçalara ayırıp değişen yollar üzerinden göndermeye benzer. Bir yol tıkanırsa başka yol denenebilir; esneklik, internetin derin fikirlerinden biri hâline gelir.
