Definisi
Kapasitas transfer data maksimum suatu saluran komunikasi, biasanya diukur dalam bit per detik (bps, Mbps, Gbps).
Penjelasan
Bandwidth represents the theoretical ceiling, not the actual speed achieved in practice. A fiber link may have 1 Gbps bandwidth but deliver less throughput due to protocol overhead and network congestion. The term originates from radio engineering, where it described the range of frequencies a channel could carry. Consumer broadband plans typically offer 100 Mbps to 1 Gbps downstream bandwidth.

RELATED TERMS
Bit dan Byte
Bit adalah satuan terkecil informasi digital, mewakili 0 atau 1; byte adalah kelompok 8 bit yang mampu mewakili 256 nilai berbeda.
Prefiks Biner
Prefiks biner (KiB, MiB, GiB) menyatakan pangkat 1024, berbeda dengan prefiks metrik SI (KB, MB, GB) yang menyatakan pangkat 1000.
Latensi
Penundaan waktu antara pengiriman paket data dari sumber hingga diterima di tujuan, biasanya diukur dalam milidetik (ms).
Throughput
Laju aktual di mana data berhasil ditransfer melalui jaringan atau sistem dalam periode waktu tertentu, diukur dalam bit atau byte per detik.
Kecepatan Jam (Clock Speed)
Frekuensi di mana prosesor mengeksekusi siklus, diukur dalam hertz (Hz), dengan CPU modern beroperasi dalam kisaran gigahertz (GHz).
