Internet Infrastructure

Assalamualaikum,

Pada permulaan minggu ini, saya dan rakan-rakan dikehendaki untuk menjawab mid test bagi topik yang telah dipelajari sepanjang 8 minggu di dalam kelas telekomunikasi dan rangkaian. Selepas itu, pensyarah memulakan sesi p&p dengan menerangkan topik yang bertajuk infrastruktur internet. Saya telah membuat sedikit rumusan berkaitan topik yang diajar :
