Merhaba arkadaşlar
Bugünkü çalışmamızda kaynak toplama hakkında nasıl yol alabileceğimizi göstermek istiyorum.
Kaan Aslan hocamız C dilini UNIX işletim sistemiyle bağlantılı olarak anlatmış ve UNIX işletim sisteminin doğuşu ile bağlantılı olarak tasvir etmiştir.
Wikipedia ve diğer kaynaklardan yararlanıp bilgilerimizi zenginleştireceğiz.
Teşekkürler.
