Answer:
- The simplified expression is:
- The simplified expression is undefined for m=3
Explanation:
The given expression is:
The numerator can be siplified by using factorization and denominator will be simplified using the formula
So,
A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.
So,
Hence,
- The simplified expression is:
- The simplified expression is undefined for m=3
Alternative 1:A small D-cache with a hit rate of 94% and a hit access time of 1 cycle (assume that no additional cycles on top of the baseline CPI are added to the execution on a cache hit in this case).Alternative 2: A larger D-cache with a hit rate of 98% and the hit access time of 2 cycles (assume that every memory instruction that hits into the cache adds one additional cycle on top of the baseline CPI). a)[10%] Estimate the CPI metric for both of these designs and determine which of these two designsprovides better performance. Explain your answers!CPI = # Cycles / # InsnLet X = # InsnCPI = # Cycles / XAlternative 1:# Cycles = 0.50*X*2 + 0.50*X(0.94*2 + 0.06*150)CPI= 0.50*X*2 + 0.50*X(0.94*2 + 0.06*150) / X1= X(0.50*2 + 0.50(0.94*2 + 0.06*150) ) / X= 0.50*2 + 0.50(0.94*2 + 0.06*150)= 6.44Alternative 2:# Cycles = 0.50*X*2 + 0.50*X(0.98*(2+1) + 0.02*150)CPI= 0.50*X*2 + 0.50*X(0.98*(2+1) + 0.02*150) / X2= X(0.50*2 + 0.50(0.98*(2+1) + 0.02*150)) / X= 0.50*2 + 0.50(0.98*(2+1) + 0.02*150)= 3.97Alternative 2 has a lower CPI, therefore Alternative 2 provides better performance.
Answer:
The answer to this question can be described as follows:
Explanation:
Relational data model:
The use of data tables to organize sets of entities into relationships requires a relational data model. this model work on the assumption, which is a primary key or code, that is included in each table configuration. The symbol for "relational" data links and information is used by other tables.
Model Design:
This model is used for database management, it consists of structure and language consistency. It is design in 1969.
Importance of data model:
This provides a common standard for processing the potentially sound data in machines, that was usable on almost any one device.
Big Data:
It moves to locate new and innovative ways to handle large volumes of authentication tokens and to gather business insights when offering high efficiency and usability at an affordable cost at the same time.
Answer:
Hallmark is using the Age segmenting dimension.
Explanation:
Most businesses and organizations tend to understand their customers, that is, their behaviors on purchases.
There are 7 important ways businesses segment their customers. They are:
- Income
- Age
- Gender
- Acquisition Path
- First purchase
- Geography
- Device type
In our scenario, Hallmark is using the Age segmenting dimension because they can identify that its a teenage girl that is sending theme card to her boyfriend's cell phone.
