Answer:
B) 2.22
Explanation:
In a first step, the system will look in cache number 1. If it is not found in cache number 1, then the system will look in cache number 2. Finally (if not in cache 2 also) the system will look in main memory.
The average access time will take into consideration success in cache 1, failure in cache number 1 but success in cache number 2, failure in cache number 1 and 2 but success in main memory.
Mathematically we can write it into the following equation :

Where AAT is the average access time
H1,H2 and Hm are the hit rate of cache 1,cache 2 and main memory respectively.
T1,T2 and Tm are the access time of cache 1, cache 2 and main memory respectively
Hm = 1


Therefore, option b) is the correct.
Answer:
Computer Aided Design (CAD)
Explanation:
For design purpose and rapid prototyping, we use a software known as Computer Aided Design abbreviated as CAD.
Several production formates that are used in CAD are .stp, .stl, .igs, .step where formats like .stp, .igs and .step are used for rapid prototyping and format like .stl is used for design.
The information depending on the extensions used can be modeled in the 3-D files. The most frequent software used for prototyping are: AutoCAD, SolidWorks, SketchUP, etc
This also allows the spatial manipulation, dimension measurement and the visualization of the inner and outer parts.
Answer:
The steady-state temperature difference is 2.42 K
Explanation:
Rate of heat transfer = kA∆T/t
Rate of heat transfer = 6 W
k is the heat transfer coefficient = 152 W/m.K
A is the area of the square silicon = width^2 = (7/1000)^2 = 4.9×10^-5 m^2
t is the thickness of the silicon = 3 mm = 3/1000 = 0.003 m
6 = 152×4.9×10^-5×∆T/0.003
∆T = 6×0.003/152×4.9×10^-5 = 2.42 K
Answer:
They are both correct
Explanation:
When someone is asking a question of you, it means he or she has either been paying attention, and is interested in you, what you're doing, or what you're saying. Also, silence when used properly can be golden in the sense that it can prevent unnecessary problems from arising, and can save one from a lot of unforeseen problem. Whatever is said cannot be taken back again, and some things should never be said at all, especially in a professional setting.
