Suppose that we can improve the floating point instruction performance of machine by a factor of 15 (the same floating point ins

tructions run 15 times faster on this new machine). What percent of the instructions must be floating point to achieve a Speedup of at least 4?

Answer:

Answer to the following question is 80.36.

Explanation:

We use an Amdahl’s Law.

Let x be the percentage of a floating-point instruction.  

Since, the speedup = 4,  

if the program executed 100 cycles then, this program will runs 100/4 = 25 cycles

\frac{100}{4} = \frac{x}{15} + (100-x)

Solve  x, we get:

x = 80.36

A personal identification number (PIN) that opens a certain lock consists of a sequence of 3 different digits from 0 through 9,
Elan Coil [88]

Answer:

<u>720</u> possible PIN can be generated.

Explanation:

To calculate different number of orders of digits to create password and PIN, we calculate permutation.

Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:

nPr = n!/(n-r)!

there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)

So in question we need to calculate

P=?

where

n= 10   (0-9 means total 10 digits)

r= 3     (PIN Consist of three digits)

So by using formula

10P3 = 10!/(10-3)!

        =10!/7!

        = 10x9x8x7!/7!

        = 10x9x8

        = 720

Why are duplicate tuples not allowed in a relation?
velikii [3]

Answer:

Explanation:

Duplicate tuples are not allowed in a relation because the specifications of the constraints of the regional integrity are violated, especially the main constraint that states that there can be no identical values for the attributes of two tuples at any database relation state.

Also, duplicate tuples are not allowed in a relation due to the fact that they lead to redundancy of the data base which in turn, slowing down the speed of the database when data processing such as inserting, querying, updating, deleting, etc are being performed.

ale4655 [162]

Answer:

The answer is D and E

Explanation:

There is no much difference between a port replicator and a docking station. These two terms are used interchangeably and both serve the same purpose of connecting portable computers with other devices with little or no effort. The main difference between the two is that a port replicator provides a solution for all laptops through USB while a docking uses a propriety connector to the computer. Users can use a docking station and a port replicator to convert their laptop PCs into desktop computers when at home or in the office.
