7. Translate these passages in writing:
a) Every time you use a domain name, you use the Internet's DNS servers to translate the human-readable domain name into the machine-readable IP address.
b) One of the keys to making this work is redundancy. There are multiple DNS servers at every level, so that if one fails, there are others to handle the requests. The other key is caching. Once a DNS server resolves a request, it caches the IP address it receives.
c) Even though it is totally invisible, DNS servers handle billions of requests every day and they are essential to the Internet's smooth functioning. The fact that this distributed database works so well and so invisibly day in and day out is a testimony to the design.
