I can help with most of these!

#1: Explain the use of logic gates.

Answer: Logic gates are comparisons to operations that are performed in the CPU using keywords such as, OR, XOR, NOT, AND, NAND, XNOR, and NOR.

#2: ____ refers to logic in programming and errors in program code.

Answer: BUGS refers to logic in programming and errors in program code.

#3: What type of software resides on a computer’s hard drive, and controls the CPU and all other activity between components?

Answer: The operating system!

#4: Why are high-level languages easier for humans to understand?

Answer: They are written with human-friendly words that humans understand.

#5: Which component receives data and loads it into memory for use?

Answer: The CU!

#6: Explain why a CPU’s speed is affected by the number of buses.

Answer: Each bus is basically a highway on the motherboard that is enabling data transfers from and to the CPU. So, since there are numerous buses, large amounts of data are being transferred. This is how the CPU's speed is affected.

#7: What's the keyword for a field that stores a true/false value?

Answer: Boolean

#9: How is Windows 8 different from an Internet browser such as Firefox?

Answer: Windows 8 is system software; Firefox is application software.

#10: Which computer programming language would be most easy to understand if you have never seen it before? Choose the best answer.

Answer: Javascript language!

#11: Which part of the CPU provides access to the external cache unit and other CPUs on the motherboard?

Answer: The southbridge!

#14: What is a user-friendly software program that displays information to the user, accepts input from the user, and provides output for the user?

Answer: Human-computer interface!

#15: What is a group of printable characters enclosed within double quotation marks called?

Answer: String Literal!

#16: Which component comprises the central processing unit?

Answer: The Control unit!

#17: What typically handles communications among the CPU, in some cases RAM, PCI Express (or AGP) video cards, and the southbrige?

Answer: The northbridge!

#18: Explain why clock speed is used to measure a computer’s speed in calculation and processing data.

Answer: Clock speed is the measurement of how many cycles a CPU can process. When the processor speed or CPU is compared to different computers, the higher the clock speed is, the more efficient and faster the computer will run.

#19: Choose the following components that are controlled by the motherboard.

Answer: The CPU cooling fan, power supply and internal speaker are all controlled by the motherboard.

#21: When does the ALU get activated? Choose the most appropriate answer.

Answer: Once an instruction that involves a calculation comes to the CPU.

#22: Which of the following makes up binary code?

Answer: 1s and 0s!

Cuando se creo argentina

vekshin1

Answer:

Argentina se creó tras su independencia respecto de España el 9 de julio de 1816, tras 6 años de guerra por la independencia del país, donde líderes como Manuel Belgrano, Martín Miguel de Güemes y José de San Martín derrotaron a los españoles.

La unidad nacional de los argentinos, a su vez, se originó tras las invasiones inglesas de 1806 y 1807, y se consolidó tras la conquista de España por parte de los Bonaparte, que dio origen a la Revolución de Mayo de 1810, donde los argentinos decidieron imponer un gobierno propio.

A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment

Two factors may interfere with the copper cabling and result in signal distortion and data corruption are :

EMI

RFI

Explanation:

EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
During EMC testing, radiated emissions measurements are made using a spectrum analyzer and or an EMI receiver and a suitable measuring antenna.
EMI (Electromagnetic Interference) is also called RFI (Radio Frequency Interference).
Conducted RFI is unwanted high frequencies that ride on the AC wave form. Radiated RFI is emitted through the air. There are many pieces of equipment that can generate RFI, variable frequency drives included.
The internal circuits of personal computers generate EM fields in the RF range.

Annette [7]

Answer:

3. ISDN

Explanation:

ISDN ( Integrated Services Digital Network ) -

It is the used for the simultaneous digital transmission of network service , data , video and voice , instead of the old circuits of the public switched telephone network ( PSTN ) , is referred to as ISDN .

The characteristic feature of ISDN is that it integrates the data and speech on the same lines , which is not possible in PSTN .

Hence, from the given information of the question,

The correct option is ISDN .

Write a program that teaches arithmetic to a young child. The program tests addition and subtraction. In level 1 it tests only a

Natasha2012 [34]

Answer:

import random

class Arithmetics(object):

trial = 2

score = 0

is_end = "Y"

def start(self):

while self. is_end == "Y":

self. level1()

self. level2()

self. level3()

self. is_end = input("Do you want to play again? Y/N: "). upper()

quit()

def level1(self):

print("--------------------Level 1--------------------\n\n Addition:")

for _ in iter(list, 0):

num1 = random.randint(1,5)

num2 = random.randint(1,5)

if self. score == 5:

print("Congrat! advance to next level\n")

self. init_()

break

print(f"{num1} + {num2}")

result = int(input("Your answer: "))

if result == num1 + num2:

self. increase_score()

elif self. trial == 0:

print("Sorry dear, you failed to pass the text.")

self. end_game()

else:

self. trial_reduce()

def level2(self):

print("--------------------Level 2--------------------\n\n Addition again:")

for _ in iter(list, 0):

num1 = random. randint(1,9)

num2 = random. randint(1,9)

if self. score == 5:

print("Congrat! advance to next level\n")

self. init_()

break

print(f"{num1} + {num2}")

result = int(input("Your answer: "))

if result == num1 + num2:

self. increase_score()

elif self. trial == 0:

print("Sorry dear, you failed to pass the text.")

self. end_game()

else:

self. trial_reduce()

def level3(self):

print("--------------------Level 3--------------------\n\n Subtraction:")

for _ in iter(list, 0):

denum = random. randint(6,9)

num = random. randint(1,5)

if self. score == 5:

self. init_()

self. end_game()

break

print(f"{denum} - {num}")

result = int(input("Your answer: "))

if result == denum - num:

self. increase_score()

elif self. trial == 0:

print("Sorry dear, you failed to pass the text.")

self. end_game()

else:

self. trial_reduce()

#classmethod

def trial_reduce(cls):

cls. trial -= 1

#classmethod

def increase_score(cls):

cls. score += 1

#classmethod

def init_(cls):

cls. trial = 2

cls. score = 0

def end_game(self):

print("Congrats kiddo! You are a math wiz.")

game = Arithmetics()

game. start()

Explanation:

The python class defines the arithmetics class with three-level mathematics for children defined as methods for the class. There are three class methods namely; 'trial_reduce', 'increase_score', and 'init_' with each of them decreasing the trial attribute, increasing the score attribute by one, and initializing the class attributes to its initial state.

The 'end_game' prints a message at the end of the program. Each level is in a loop and counts five times if the answers are correct.
