Answer:
A.
Explanation:
Answer D seems too simplistic, and the question specifically mentions IT practices.
Question B doesn't seem right - college and high school students would likely be able to understand the principles as much.
Question C wouldn't be a good argument for a school board, and there's not a lot of evidence that backs it up.
Therefore, A seems to be the best choice here.
Hope this helps!
I believe it’s B)LAN
Explanation:
A LAN connects computers over a relatively short distance, allowing them to share data, files, and resources. For example, a LAN may connect all the computers in an office building, school, or hospital. Typically, LANs are privately owned and managed.
Answer:
128 bits
Explanation:
The MD5, which is the acronym for Message-Digest algorithm 5, invented by a professor of MIT, Ronald Rivest, is a cryptographic hash algorithm that creates a 128 bit hash value and is typically represented as a 32 character hex number. MD5 is the improved version of MD4 which was also created by the same professor.
Following is an example format of an MD5 hash;

MD5 has been proven to have security issues. One of these issues is called collision attack - a situation where the same hash is produced for different input data.
<h2>
APPEND ONLY</h2>
Unlike traditional databases, blockchain is designed to be an "append-only" data structure. That means you can only append new data in the form of additional blocks, which will then be chained together with previous blocks of data. All data is permanently stored across more nodes and cannot be altered.
