A web browser requests a webpage from a web server. The page consists of:
1 HTML file of size 30 KB
6 images, each of size 120 KB
The network throughput is 8 Mbps. Ignore TCP connection setup and latency. Find the total time to download the complete webpage.
Show answer & explanation
Given Data
HTML file size = 30 KB
Number of images = 6
Each image size = 120 KB
Network throughput = 8 Mbps
Step 1: Total Data Size
Total image size:
6 × 120 = 720 KB
Total data:
30 + 720 = 750 KB
Step 2: Convert into Bits (Networking Standard)
In data communication:
1 KB = 1000 Bytes, 1Byte = 8 bits
750 KB = 750 × 1000 = 750000 Bytes
750000 × 8 = 6×106 bits
Step 3: Throughput
8 Mbps = 8 × 106 bits/sec
Step 4: Download Time
Final Answer
Total download time=0.75 seconds
