Answer:
The application should have a form user interface to submit input, the input is used to query a database, if the input matches a row in the database, the value is displayed in the application.
Explanation:
The data structure in the database for the dictionary application should be a dictionary, with the input from the user as the key and the returned data as the value of the dictionary.
The dictionary application should have a user interface form that submits a query to the database and dictionary data structure returns its value to the application to the user screen.
People from this cultural group are more tolerant to new ideas and opinions that differ from their own
A) North Americans
B) People with low uncertainty avoidance
C) None of these
D) People with high uncertainty avoidance
Answer:
B) People with low uncertainty avoidance
Explanation:
Uncertainty avoidance is how cultures differ on the amount of tolerance they have of unpredictability. Mostly, uncertainty avoidance deals with technology, law, and religion. People with low uncertainty avoidance cultures accept and feel comfortable in unstructured situations or changeable environments and tend to be more pragmatic and more tolerant of change. People in cultures with high uncertainty avoidance try to minimize the occurrence of unknown and unusual circumstances.
Compute the overall (Cache) performance CPU:
A processor runs at 3.0 GHz and has a CPI=1.5 for a perfect cache (i.e. without including the stall cycles due to cache misses). Assume that load and store instructions are 25% of the instructions. The processor has an I-cache (Instruction – cache) with a 5% miss rate and a Dcache (Data memory cache) with 4% miss rate. The hit time is 1 clock cycle for both caches.
Assume that the time required to transfer a block of data from the main memory to the cache, i.e. miss penalty, is 40 ns.
a. Compute the number of stall cycles per instruction
b. Compute the overall (cycle per instruction) CPI
c. Compute the average memory access time (AMAT) in ns.
Answer:
See explanation.
Explanation:
Given:
Instruction miss rate = I-cache miss rate = 5% = 0.05
Data miss rate = D-cache miss rate = 4% = 0.04
CPI (without including the stall cycles) = 1.5
Miss Penalty = 40 ns × 3 GHz = 120 cycles
load and store instructions = 25% = 0.25
hit time = 1 clock cycle
a. Compute the number of stall cycles per instruction
Instruction miss cycles = I-cache miss rate * miss penalty
= 0.05 * 120
= 6
Data miss cycles = D-cache miss rate * miss penalty * load and store
instructions
= 0.04 * 120 * 0.25
= 1.2
Total memory stall cycles = Instruction miss cycles + Data miss cycles
= 6 + 1.2
= 7.2
number of stall cycles per instruction = 7.2
b. Compute the overall (cycle per instruction) CPI
CPI (stall) = 1.5 + 7.2
= 8.7
Ideal CPU = CPU time with stalls / CPU time with perfect cache
= I x CPI (stall) x Clock cycle/ I x CPI x Clock cycle
= 8.7 / 1.5
= 5.8
c. Compute the average memory access time (AMAT) in ns.
Combined misses per instruction = 0.05 + 0.25 * 0.04 = 0.06
Combined Miss Rate = Combined misses per I/ 1.25 access per I
Combined Miss Rate = 0.06 / 1.25 = 0.048
Average Memory Access time (AMAT) = Hit time + Miss rate × Miss penalty
= 1 + 0.048 * 120
= 6.7
= 6.76 cycles
= 6.76 / 3
= 2.253 ns
AMAT = 2.253 ns
Companies expose themselves to harsh sanctions by federal agencies when they violate the privacy policies that their customers rely upon.
a. True
b. False
Answer:
True
Explanation:
A privacy policy is a legal document or statement that discloses the ways a party gathers uses and manages a customer's data. These data include personal information such as address, name, financial records, medical history, travel records etc.
Policies such as the Children Online Privacy Protection Act which protects children on websites collecting children's data, the Gram-Leach-Bliley Act, The Health Insurance Portability and Accountability Act, are in place to ensure that privacy is protected and sanctions are metted out to violating companies.
Digital certificates, smart cards, picture passwords, and biometrics are used to perform which of the following actions?
a. Integrity
b. Confidentiality
c. Authorization
d. Authentication
Answer:
d. Authentication.
Explanation:
In Computer technology, authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
Digital certificates, smart cards, picture passwords, and biometrics are used to perform an authentication.
Consider two decision problems X and Y. If X reduces in polynomial time to 3-SAT and 3-SAT reduces in polynomial time to Y. Which of the following can be inferred from the previous statement?
a. X is in NP and Y is in NP-Hard.
b. Y is in NP and X is in NP-Hard.
c. Both X and Y are in NP-hard.
d. Both X and Y are in NP.
Answer:
X is in NP and Y is in NP-HARD ( A )
Explanation:
X is in NP and Y is in NP-HARD can be inferred from the previous statement made in the problem above because problem decision X can be in NP if it can BE reducible to a 3-SAT polynomial real time, if that can be achieved then 3SAT will be in NP since SAT is in NP as well.
also problem decision Y can be in NP-HARD if 3SAT can be reducible to it in polynomial time as well hence option A is the correct option
____________ are used to store all the data in a database
Answer:
The correct answer is data store
Explanation:
there are primarily three methods of programming in use today: procedural, recursive, and object oriented true or false
Answer:
False.
Explanation:
In Computer programming, there are primarily two (2) methods of programming in use today:
1. Procedural programming: it is an early form of programming (coding) in which software developers make use of a top to down approach in instructing the computer on what actions to take through logical or step-by-step processes. This top-down approach is known as an inline programming, it basically involves calling a procedure such as functions, routines or sub-routines. Some examples of a procedural programming language are Java, Pascal, C, BASIC and FORTRAN.
2. Object-oriented programming (OOP): it is a high level programming language which is based on creating objects that comprises of data (fields) and code (procedures). This procedure includes a method while the data that makes up the object is generally referred to as fields and includes arrays, variables, class etc. Some examples of object-oriented programming language are Python, Ruby, Raku, Java, C++ etc.
Generally, in computer programming a procedural programming is primarily based on creating procedures while an object-oriented programming is based on the creation of objects.
We will extend this idea to streams. Write a function called rle that takes in a stream of data, and returns a corresponding stream of two-element lists, which represents the run
Answer:
def rle(data_stream ):
with open( "data_stream" ) as file:
container= [ ]
two_itemlist= [ ]
while True:
container.append( file.readlines )
file.close( )
while container == True:
value= container.pop(0)
split_value= value.split( " " )
while split_value == True:
while len( two_itemlist) < 2:
holder = split_value.pop( 0 )
two_itemlist.append( holder )
yield two_itemlist
new_list = rle ( new_file )
Explanation:
In the solution above, the defined function is a generator, as it continuously returns a two-element list.
Describe conceptually how an sql retrieval query will be executed by specifying the conceptual order of executing each of the six clauses
Answer:
Answered below
Explanation:
An SQL retrieval query contains six clauses which are executed in an orderly sequence. These clauses include; SELECT, FROM, WHERE, GROUP BY, HAVING and ORDER BY.
The select clause enables us specify the data we want to retrieve. This statement is the starting point of SQL queries.
The FROM statement comes second and specifies the table the data is being retrieved from.
The WHERE clause helps us limit the data to those that meet a particular condition.
The GROUP BY statement helps group your information in a more meaningful way.
The HAVING clause puts a condition on your group.
The ORDER BY statement orders your information in descending order or ascending order.

Who should perform the validation test, the software developer or the software user?
If I execute the expression x <- 4L in R, what is the class of the object `x' as determined by the `class()' function?
Answer:
integer
Explanation:
The expression can be implemented as follows:
x <- 4L
class(x)
Here x is the object. When this expression is executed in R, the class "integer" of object 'x' is determined by the class() function. R objects for example x in this example have a class attribute determines the names of the classes from which the object inherits. The output of the above expression is:
"integer"
Here function class prints the vector of names of class i.e. integer that x inherits from. In order to declare an integer, L suffix is appended to it. Basically integer is a subset of numeric. If L suffix is not appended then x<-4 gives the output "numeric". Integers in R are identified by the suffix L while all other numbers are of class numeric independent of their value.
Use the words: Explain, Compare. Create a question using "explain" as the verb. Answer that question.

write a pseudocode thats accept and then find out whether the number is divisible by 5
Answer:
input number
calculate modulus of the number and 5
compare outcome to 0
if 0 then output "divisible by 5"
else output "not divisible by 5"
Explanation:
The modulo operator is key here. It returns the remainder after integer division. So 8 mod 5 for example is 3, since 5x1+3 = 8. Only if the outcome is 0, you know the number you divided is a multiple of 5.
which statement compares the copy and cut commands?
1. only the copy command requires the highlighting text
2. only to cut command removes the text from the original document
3. only the cut command uses the paste command to complete the task
4. only the copy command is used to add text from a document to a new document
Answer:
only to cut command removes the text from the original document
Explanation:
To say that only the cut command removes the text from the original document implies that you can use the cut command on a text, let's say "a boy and girl" to remove the text on the original document where it was located to a new document or text box, in other words, the text "a boy and girl" would no longer be found in the original document.
However, the copy command would not remove the text from the original document.
Answer:
only the command removes the text from the original document.

You have just used a command that produced some interesting output on the screen. You would like to save that information into a file named "interesting.txt", which does not currently exist. You can do this by issuing the same command, but appending which of the following?
A. > interesting.txt
B.
C. interesting.txt
D. | interesting.txt
Answer: A. > interesting.txt
Explanation: From the command line, one can perform numerous tasks from navigating into a directory, creating a new directory, deleting files, create files, modify files and so on using simple commands. In the scenario above, after using a common which is used to produce an output on the screen, such as the 'echo' command, one may wish to save the file giving the user the ability to access the file later. Since it is stated the file name 'interesting.txt' given to the file does not currently exist, appending the sign > saves the file. If the filename already exists, it will overwrite the existing content.
Assume that the variables v, w, x, y, and z are stored in memory locations 200, 201, 202, 203, and 204, respectively.
Using any of the machine language instructions in
Section 5.2.4, translate the following algorithmic operations into their machine language equivalents.
a. Set v to the value of x – y + z. (Assume the existence of the machine language command SUBTRACT X, Y, Z that computes CON(Z) = CON(X) – CON(Y).)
b. Set v to the value (w + x ) - ( y + z)
c. If (v ≥?w) then
set x to y Else set x to z
d. While y < z do
Set y to the value ( y + w + z)
Set z to the value (z + v)
End of the loop
Answer and Explanation:
A. To translate the above algorithm to machine language, we first assign have to perform the first part of the operation which is x-y and set the value to the v variable. The x, y and v values are stored in memory location 202, 203 and 200 respectively.
The z value in the memory location 204 is then added to the v value in memory location 200. The first code sequence is stored in memory location 50 and the second code sequence to achieve x+y-z stored in v is stored in memory location 51(as asummed in question)
B. In the second algorithm, we add value in w which is in memory location 201 to value in x in memory location 202 and assign the result to v in memory location 200. The same is done for y+z in memory locations 203 and 204 respectively with result stored in w. We then subtract the values in v in memory location 200 from w and assign the value to v in memory location 200
C. in the first memory location 50, the code sequence v compared to w is stored. If v(stored in memory location 201)is greater than or equal to w(in memory location 202), it moves to address 54 and assigns the y value to x in memory locations 203 and 202 respectively else it assigns z valuein memory 204 to x value in 202 and jumps to next instruction
D. In this algorithm, it first compares y and z in memory locations 203 and 204 respectively in the first code sequence memory 50. In 51, it checks to see if the condition is satisfied and if it is, it jumps to address 53 and adds y and w in their various memory locations and stores it in memory 203 in y otherwise it moves to address 57. Now to get y+w+z, It then adds y +w in memory location 203 in y to z in memory location 204 and then stores the result in y. Subsequently it adds the z value to v and stores the result in v and moves to address 50 where it compares a new set of value as in a loop in the algorithm which continues till the "while" condition can no longer be satisfied.

How can software assist in procuring goods and services?
What is e-procurement software?
Do you see any ethical issues with e-procurement?
For example, should stores be able to block people with smartphones from taking pictures of barcodes to do comparison shopping?
Answer:
Answered below
Explanation:
E-procurement software is the enterprise software that integrates and automates an organisation's procurement processes.
E-procurement software assists in procuring goods and services by allowing customers to browse online catalogs and stores, add their goods to shopping carts and send their requisition. This process reduces errors and improves efficiency.
Ethics of procurement include integrity, impartiality, fairness and transparency. Stores shouldn't block customers from doing comparison shopping.

4. Write a script called lineCounter that accepts a filename as a command line argument. It should run through the file line by line, displaying a character count for each line. The script should include a line counter, which records the line number, and is incremented when each line is processed.
Answer:
from sys import argv
script, filename = argv
with open( filename ) as file:
line_counter = 0
while True:
extract_line = file.readlines( )
line_counter += 1
character_count = extract_line.count( )
print( " line number: { } , character count: { }". format( line_counter, character_counter )
print ( " Nothing left to count" )
file.close( )
Explanation:
The 'argv' is a module in the python system package, which allows for user input and script execution in the command. It loads the script and the file as a tuple which is offloaded in the script like arguments in a function.
Security problems with master keys include (mark all that apply): Master keys are easier to copy than other keys. Master keying reduces the number of useful combinations. Locks that have the master pins needed for master keys are easier to pick. Unauthorized master keys will permit access to any lock in the series.
Answer:
- Master keys are easier to copy than other keys.
- Unauthorized master keys will permit access to any lock in the series.
Explanation:
This is the sad reality when an individual who's unauthorized gains access to a master key, then, he may be permitted access to any lock in the series.
Also, rather trying to copy other keys, it will be far easier to copy just one key– the master key.

Flowchart of an algorithm (Euclid's algorithm) for calculating the greatest common divisor (g.c.d.) of two numbers a and b in locations named A and B. The algorithm proceeds by successive subtractions in two loops: IF the test B ≥ A yields "yes" or "true" (more accurately, the number b in location B is greater than or equal to the number a in location A) THEN, the algorithm specifies B ← B − A (meaning the number b − a replaces the old b). Similarly, IF A > B, THEN A ← A − B. The process terminates when (the contents of) B is 0, yielding the g.c.d. in A. (Algorithm derived from Scott 2009:13; symbols and drawing style from Tausworthe 1977).
