Answer:
The Random-Access Memory (RAM) should be upgraded.
Explanation:
Since the particuar apllication is taking alot of memory space it means that an ugrade/ installation of a bigger RAM would help the system work better while using the program
Answer:
The "a" Option is correct.
Explanation:
The "COUNTIF" function counts every cell that, given a condition (value), suits into it. As you want to know the number of cells that contain a value of at least 50, the condition must be properly written to get the correct answer. Unless it is a cell value (e.g. B3), the condition must always be written with quotes (""). So, the options b and c are automatically discarded.
The d option appears to be correct, but it's not. If the condition is written ">50", the function will count every cell with a value above 50. But we're searching values at least (including) 50. So the correct answer is the a option.
Modems create an analog signal that carries digital data on it,
and strip the digital data from an analog signal that they receive.
That's what's needed to connect through the telephone system,
since the telephone system is still one big analog system.
Answer: Supermarket bar code scanners and Voice-activated telephone menus are not instances of artificial intelligence
Explanation:
(a)Supermarket bar code scanners are only able to read the code however they are not able to perform any kind of machine learning techniques to be able to learn a sequence from the codes. As machine learning is a important part of artificial intelligence (AI) so they are not instances of AI. Similarly for Voice-activated telephone menus they could only display and cannot perform any intelligent task.
Web search engines and Internet routing algorithms are very dynamic and intelligent in processing and retrieving information to the end user.
So they are instances of AI.
