Answer:
I think cold day instead
Explanation:
Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion.
Answer:
True
Explanation:
A dictionary attack is an attempts to gain illegal access to a computer system by hashing all the words in a dictionary and then systematically entering each hashed value as a password so as to discover a match. it has been the most successful password guessing technique over the years because many users and organization use ordinary words as passwords.
Answer: D. Turing conceived the structure of a programmable computer.
Explanation: The passage describes how Alan M. Turing described the theoretical aspect of a programmable computer. There is no reference to a physical machine or Turing working on an actual (physical) computer.
The Turing machine, although it does sound like a physical computer was an abstract idea, conceived in mathematical form of what a programmable machine would be like. Alan Turing is considered one of the founding fathers of theoretical computer science.
Answer: Twisted pair cable
Explanation:
Twisted pair cabling simply refers to a wiring whereby two conductors that are gotten from a single circuit will be twisted together so that their electromagnetic compatibility can be enhanced.
This type of network cable is commonly used to connect office computers to the local network and it is used for Ethernet networks. A circuit is formed from the pair of wires which can be used in the transmission of data.
Answer:
The overall speedup gained by incorporating the enhancement is 1.563
Explanation:
Using Amdahl's Law;
The overall speedup
where;
P = Fraction Enhanced for Old Processor
n = speedup enhancement as a result of the new processor
P = 40% = 0.40 and n = 10
∴
The overall speedup (N) is:
= 1.563
Thus, the overall speedup gained by incorporating the enhancement is 1.563
