Definitions Bank

A. A connected car downloading software updates while driving through a city.

B. Short-range wireless network around 20 meters, best for walking around a room.

C. Four sets of numbers separated by dots (e.g., 192.168.1.13).

D. When a data piece fails to arrive, triggering a request for a replacement copy.

5. Arrange in Proper Sequence

Put the steps of each process into the correct numerical order (1 to 4).

Sequence A: Journey of Data Packets across a Network

Packets travel across different internet routes at different speeds.

The destination computer uses sequence numbers to put packets back in order.

The original file or message is split into smaller, equal-sized packets.

Packets are sent out onto the internet network.

Sequence B: Accessing a Website using a Web Browser

The web server checks for the requested page and streams data back to the user.

The web browser converts the text URL into a numerical IP address.

You type a text URL into your web browser address bar.

The browser uses the IP address to locate and connect to the web server.

6. True or False

State whether each statement is True or False. If False, write a one-sentence correction.

a) All data packets sent across the internet are forced to take the exact same route.

True False

b) Cellular networks use tall towers to transmit wireless signals over large distances.

True False

c) If a packet is lost during transmission, the entire file must be retransmitted from the beginning.

True False

d) An Ethernet connection is wireless and connects devices using radio towers.

True False

e) A website is a collection of linked web pages stored on a web server.

True False

f) Computers process URLs using letters because they do not understand numbers.

True False
