vitfil [10]

Answer:

The answer is Bootsrap

Explanation:

A bootstrap program which is also referred to as a bootstrap loader is a program that resides in the computer’s Read Only Memory. It starts the whole chain reaction and ends up with the entire OS being loaded. This program reads the computer’s hard drive boot sector and continues with the process of loading the Operating System. It first performs a POST test and then proceeds to load the OS intothe main memory.

Write a program that creates a dictionary containing the U.S. states as keys and their abbreviations as values. The program shou

AleksandrR [38]

Answer:

Explanation:

The following program is written in Python. It creates a loop that keeps creating a random number to randomly choose a State abbreviation from the dictionary. Then it asks the user what the state is. If the user gets the answer correct it prints out "Correct" and adds 1 point to the correct variables. Otherwise it prints "Incorrect" and adds 1 point to the incorrect variable. Finally, printing out the final amount of correct and incorrect responses. The program was tested and the output can be seen below.

import random

states = {"AL":"Alabama","AK":"Alaska","AZ":"Arizona","AR":"Arkansas","CA":"California","CO":"Colorado","CT":"Connecticut","DE":"Delaware","FL":"Florida","GA":"Georgia","HI":"Hawaii","ID":"Idaho","IL":"Illinois","IN":"Indiana","IA":"Iowa","KS":"Kansas","KY":"Kentucky","LA":"Louisiana","ME":"Maine","MD":"Maryland","MA":"Massachusetts","MI":"Michigan","MN":"Minnesota","MS":"Mississippi","MO":"Missouri","MT":"Montana","NE":"Nebraska","NV":"Nevada","NH":"New Hampshire","NJ":"New Jersey","NM":"New Mexico","NY":"New York","NC":"North Carolina","ND":"North Dakota","OH":"Ohio","OK":"Oklahoma","OR":"Oregon","PA":"Pennsylvania","RI":"Rhode Island","SC":"South Carolina","SD":"South Dakota","TN":"Tennessee","TX":"Texas","UT":"Utah","VT":"Vermont","VA":"Virginia","WA":"Washington","WV":"West Virginia","WI":"Wisconsin","WY":"Wyoming"}

keys_list = list(states)

correct = 0

incorrect = 0

while True:

randNum = random.randint(0, 49)

abbr = keys_list[randNum]

answer = input("Enter The State name of " + abbr + ": ")

if answer.lower() == states[abbr].lower():

print("Correct")

correct += 1

else:

print("Incorrect")

incorrect += 1

again = input("Play again? y/n ")

if again.lower() == 'n':

break

print("Correct: " + str(correct))

print("Incorrect: " + str(incorrect))

IRISSAK [1]

In an <u>Internet-based system</u>, the web becomes an integral part of the application, rather than just a communication channel, and systems analysts need new application development tools and solutions to handle the new systems.

d) Internet-based system

<u>Explanation:</u>

Web information system, or web-based information system, is a data framework that utilizes Internet web advancements to convey data and administrations, to clients or other data frameworks/applications.

It is a product framework whose primary intention is to distribute and keep up information by utilizing hypertext-based standards. In an Internet-based system, the Web turns into a fundamental piece of the application, instead of only a correspondence channel, and frameworks investigators need new application advancement instruments and solutions to handle the new systems.

Convert binary number 11101111.10111 to decimal

Alekssandra [29.7K]

Answer:

$N_{10}=239.71875$

Explanation:

In order to obtain the decimal number we have to use the next formula:

$N_(10)=d*2^{(i)}\\where:\\N=real number\\d=digit\\i=position$

(The position to the right of the decimal point we will take it as negative)

Using the formula we have:

$N_{10}=(1*2^7+1*2^6+1*2^5+0*2^4+1*2^3+1*2^2+1*2^1+1*2^0+1*2^{-1}+0*2^{-2}+1*2^{-3}+1*2^{-4}+1*2^{-5})$

$N_{10}=239.71875$

3.What are the pros and cons of using a linked implementation of a sparse matrix, as opposed to an array-based implementation

weqwewe [10]

Answer:

speed and storage

Explanation:

The pros and cons of both are mainly in regards to speed and storage. Due to linked lists elements being connected to one another it requires that each previous element be accessed in order to arrive at a specific element. This makes it much slower than an array-based implementation where any element can be quickly accessed easily due to it having a specific location. This brings us to the other aspect which is memory. Since Arrays are saved as a single block, where each element has a specific location this takes much more space in the RAM as opposed to a linked implementation which is stored randomly and as indexes of the array itself.

Array Implementation:

Pros: Much Faster and Easier to target a specific element
Cons: Much More Space needed

Linked Implementation

Pros: Less overall space needed
Cons: Much slower speed.
