Root name servers are the servers at the root of the Domain Name System (DNS) hierarchy. The DNS is the system which converts Internet domain names.
A recursive DNS lookup is where one DNS server communicates with several other DNS servers to hunt down an IP address and return it to the client.

5. in the example of the y2k bug, do you think that the hypothetical programmer dave took the wrong approach in storing years as only two-digits. if your group has divided opinions, say so. (2)
No and yes. While some could connected that Dave made a mistake, others might concur that it was a workable option at the time. It depends on the individual's point of view.
The Y2K bug was a computer error brought on by the programming of two-digit years. When it was thought that computers wouldn't last more than a few decades, this was a widespread technique in the 1980s and 1990s. The issue was that when the year 2000 arrived, computers wouldn't be able to tell the difference between 1900 and 2000. There was a lot of panic and confusion as a result. Because it was a realistic option at the time, hypothetical coder Dave had the forethought to save years as two-digits. However, it is feasible to argue that Dave made the incorrect decision in the long run because two-digit years may cause issues in the future.

what do mockups allow designers to do?
Answer:
Mockups are a crucial part of the design thinking process because they answer important visual questions (like layout, color, and hierarchy) and allow designers to start high-fidelity prototyping. Mockups also provide engineers with a visual reference to start the development phase.
It is created to bring life to an idea or wireframe and allows a designer to test how various visual elements work together. Mockups gives stakeholders in the page the ability to see what that page will look like while making suggestions for changes in layout, color, images, styles, and more.
Explanation:
Before committing to their designs, designers can use mockups to experiment with layouts, colors, and typography computers as well as see how their work will look in advance.
Designers can easily test out various design aspects with mockups before committing to them. A mockup is a design prototype that can be used to show how the finished product will seem. Designers may easily and quickly test out various layouts, colors, fonts, photos, and other design elements to see how they will seem in the context of the finished product by producing a mockup. This enables designers to confirm that their ideas will be appealing and functional before committing to them. Before committing to their designs, designers can get feedback on them using mockups. Designers can gain a sense of how their ideas will be viewed by others by displaying their mockups to them and making adjustments accordingly.

The subnet mask for the IP address 130.75.69.32 with a default gateway of /22 is 255.255.252.0 in dotted decimal format. To calculate the subnet mask, we convert the number of network bits to binary and then convert the binary number to dotted decimal format.
A default gateway of /22 means that the first 22 bits of the IP address represent the network address, and the remaining bits represent the host address. In this case, the first 22 bits would be set to 1, and the remaining 10 bits would be set to 0.
