The answer is E) both B and C
There are several things you can look for on a website to help you figure out if the information is reliable. The first thing you should evaluate is the audience that the website is intended for. Is it intended for academics? School children? The general public?
The next thing you should look at is the author of the website. Is the author identified? Is the author an expert in their field? Can you establish the author's credibility? Is the author affiliated to an academic institution or credible organisation?
Look at the accuracy of the website. Check for spelling errors, proper grammar, and well-written text. Are there any sources cited? Are those sources credible?
You should also check to see when the information was published. Is the information up to date? Are all of the links up to date and functioning?
There is one last thing you can look at, and this is the domain of the website. Domains like .edu and .gov are more credible than .com or .net domains.
Answer:
Running RECURSIVE-MATRIX-CHAIN is asymptotically more efficient than enumerating all the ways of parenthesizing the product and computing the number of multiplications of each.
the running time complexity of enumerating all the ways of parenthesizing the product is n*P(n) while in case of RECURSIVE-MATRIX-CHAIN, all the internal nodes are run on all the internal nodes of the tree and it will also create overhead.
Explanation:
#1) What summarizes a data source into a grid of rows and columns?
Answer: A Database. A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views, and other objects. The data are typically organized to model aspects of reality in a way that supports processes requiring information.
Answer:
Collision or electromagnetic interference (EMI)
Explanation:
Some network cables connected to switch or router ports are prone to internal collision (between two frames or packets) and external collision with electromagnetic waves from other sources (EMI).
Electromagnetic waves are also known as radio waves or signals. When they are transmitted, the network cable acts as a receiver, the received signal interferes with the packet in the cable. This is why the cyclic redundancy check (CRC) throws an error.
