Soal/Permasalahan

Buatlah sebuah aplikasi yang dapat menghitung sebuah panjang pita, lama akses dan transfer rate pada magnetic tape. Perhitungan dilakukan dengan metode blocking atau tanpa blocking. Perhitungan dijalankan dengan adanya inputan

jumlah record panjang setiap record IRG IBG blocking factor data dencity laju pita.

Algoritma

Pertama Mulai Program mengisi inputan seperti

nilai jumlah record panjang setiap record IRG IBG blocking factor data dencity laju pitanya.

Menentukan metode blocking atau tanpa blocking. Mulai perhitungan. Tampilkan hasil perhitungan. Keluar
