Repository, adalah sekumpulan paket-paket aplikasi atau program untuk sebuah sistem operasi (red : Linux) yang digunakan untuk menunjang kinerja dari sebuah aplikasi, program, dan sebagainya yang didapatkan dari Server Mirror website paket-paket tersebut. Bisa dibilang Repository ini adalah paket-paket khusus untuk sebuah sistem operasi yang kemudian paket-paket tersebut di instal untuk mendapatkan kinerja lebih baik dari sebuah sistem operasi.
Repository adalah kumpulan paket software ataupun kumpulan aplikasi yang di kumpulkan di satu tempat media dalam hal ini bisa media CD,DVD,HD,Lan ataupun internet ( mungkin ada media lain cuman yang saya tau baru itu )
Fungsi utama dari repository ini adalah installasi software atau aplikasi melalui sebuah media. Contohnya seperti paket-paket (Repository) dari Distro Linux CentOS tidak sama dengan paket-paket yang ada pada Distro Linux Debian. Karena kedua extensi tersebut, tidak kompatibel satu sama lain. Maka dari itu, agar pengguna dapat dengan mudah men-download Repository, dibuatlah Mirror Repository tersebut.
