The reason:

Q2Speedy Package

1.) Assuming that each label is 1000 bytes long, how long does it take to transmit one label over the cell network, assuming that the cell phone network operates at 14 kbps (14,000 bits per second and that there are 8 bits in a byte)?

2.) If Speedy were to upgrade to the new, faster digital phone network that transmits data at 114 Kbps (114,000 bits per second) how long would it take to transmit?



Q3 Smith, Smith, Smith, and Smith

Smith, Smith, Smith, and Smith (S4) is a regional accounting firm will be moving to a new four-story building.There will two Local Area Network in each floor.

  • List possible network errors sources
