Compare IPv4 and IPv6 addresses in terms of their structure and capacity.

Back

IPv4 addresses are 32 bits long, while IPv6 addresses are 128 bits long, allowing for more unique addresses.

Answer explanation

IPv4 addresses are 32 bits long, allowing for about 4.3 billion unique addresses. In contrast, IPv6 addresses are 128 bits long, enabling a vastly larger address space, accommodating the growing number of devices on the internet.

What does a Uniform Resource Locator (URL) specify?

Back

The protocol, domain, and path to a resource on the internet

Answer explanation

A URL specifies the protocol (e.g., HTTP), the domain (e.g., www.example.com), and the path to a resource (e.g., /page). This combination allows users to access specific resources on the internet.

How does the internet achieve fault tolerance?

Back

By using redundant pathways for data transmission

Answer explanation

The internet achieves fault tolerance by using redundant pathways for data transmission, allowing data to reroute in case of a failure. This ensures continuous connectivity, unlike the other options which do not enhance reliability.

What is the primary difference between HTTP and HTTPS?

Back

HTTPS includes encryption for secure communication, while HTTP does not.

Answer explanation

The primary difference is that HTTPS includes encryption for secure communication, protecting data during transmission, while HTTP does not provide this security, making it vulnerable to interception.

What is the primary function of the Domain Name System (DNS)?

Back

To translate URLs into IP addresses

Answer explanation

The primary function of the Domain Name System (DNS) is to translate URLs into IP addresses, allowing users to access websites using easy-to-remember domain names instead of numerical IP addresses.

Andrew uses an application to track HOW LONG it takes a packet to travel from his computer to a Wikipedia server. Which of the following is he measuring?

Back

Latency

Answer explanation

Andrew is measuring latency, which refers to the time it takes for a packet to travel from his computer to the server. Bandwidth measures data transfer capacity, while bit rate refers to the amount of data transmitted per second.
