Answer:
Computer science are the disciplines that study information, computing and the applications or ecosystems where they are developed. It is a science that comes from applied mathematics and has 3 branches that are quite well known. On the one hand we have software engineering, secondly theory as such (primary study of algorithms and data, etc.) and finally the application of the amalgam of the first two, which end up resulting in disciplines such as big data, cybersecurity or computer security, machine learning, artificial intelligence, etc. However, we are talking about a very broad science with various branches of work. Technological advances that have improved the scope of education, now allow us to develop in specific skills and computer science is one of the macro careers that have benefited the most thanks to the diversity of subjects it encompasses. This is where the on-demand courses available on the edX platform come in. Computer scientists are in one of the best times for their career advancement. We invite you to be part of the technological development and information and computing technologies through online courses.

Option B: DNS
Explanation:
Domain Name Server (DNS) is analogous to a phone book where people can look up a person name through numerical phone number. A DNS server is a database that host a database of public IP addresses (e.g. 64.233.160.0) and their associated hostname (e.g. google.com).
Whenever we type domain name in the address bar of our browser (e.g. google.com), that domain will be delivered to DNS server. Inside DNS server the URL will be mapped with its corresponding IP address making it possible for the web request to reach the the target server.
