Explanation:
Freeware and shareware programs are softwares which are either free of charge or consist of a free version for a certain trial period. These programs pose a threat of habouring malware or viruses which could damage one's computer and important files and programs. Therefore, it is imperative that carefulness is maintained when trying to get these softwares.
Some of the necessary safety conditions that should be taken include;
1) Appropriate research about the software including taking more about the vendors and reviews.
2.) Once, a healthy review has been identified ; the download can begin with the Downloader ensuring that the download is from the recommended site.
3) Prior to installation the software should be scanned with an active anti-virus program to determine if there is possibility that a virus has creeped in.
4.) Some softwares may require that computer anti-virus be turned off during installation, this is not always a good idea as this act leaves the system vulnerable a d badly exposed.
convert decimal number into binary numbers (265)10
Answer:
HELLOOOO
Alr lets start with steps by dividing by 2 again and againn..
265 / 2 = 132 ( rem = 1 )
132 / 2 = 66 ( rem = 0 )
66/2 = 33 ( rem = 0 )
33/2 = 16 ( rem = 1 )
16/2 = 8 ( rem = 0 )
8/2 = 4 ( rem = 0 )
4/2 = 2 ( rem = 0 )
2/2 = 1 ( rem = 0 )
1/2 = 0 ( rem = 1 )

Suppose a program written in language L1 must be executed on a machine running a program running in language L0. What important operation must take place
Question Completion with Options:
a. Translation of the entire L1 program into L0 code
b. Translation of the L0 program into L1 code
c. Creation of a language L3 that interprets L0 instructions
d. Interpretation of each L1 statement using L0 code as the L1 program is running.
Answer:
The important operations that must take place in this scenario are:
a. Translation of the entire L1 program into L0 code
d. Interpretation of each L1 statement using L0 code as the L1 program is running.
Explanation:
Translation enables decoding to take place. This means that the L1 program is decoded into a language that the L0 program can understand and execute. Without this translation, the higher level language of L1 will not be understood by the machine language of the L0 programs. Translation of a code creates a shared understanding, thereby easing program execution. Code translation is simultaneously accompanied by interpretation.

Write a Python program stored in a file q1.py to play Rock-Paper-Scissors. In this game, two players count aloud to three, swinging their hand in a fist each time. When both players say three, the players throw one of three gestures: Rock beats scissors Scissors beats paper Paper beats rock Your task is to have a user play Rock-Paper-Scissors against a computer opponent that randomly picks a throw. You will ask the user how many points are required to win the game. The Rock-Paper-Scissors game is composed of rounds, where the winner of a round scores a single point. The user and computer play the game until the desired number of points to win the game is reached. Note: Within a round, if there is a tie (i.e., the user picks the same throw as the computer), prompt the user to throw again and generate a new throw for the computer. The computer and user continue throwing until there is a winner for the round.
Answer:
The program is as follows:
import random
print("Rock\nPaper\nScissors")
points = int(input("Points to win the game: "))
player_point = 0; computer_point = 0
while player_point != points and computer_point != points:
computer = random.choice(['Rock', 'Paper', 'Scissors'])
player = input('Choose: ')
if player == computer:
print('A tie - Both players chose '+player)
elif (player.lower() == "Rock".lower() and computer.lower() == "Scissors".lower()) or (player.lower() == "Paper".lower() and computer.lower() == "Rock".lower()) or (player == "Scissors" and computer.lower() == "Paper".lower()):
print('Player won! '+player +' beats '+computer)
player_point+=1
else:
print('Computer won! '+computer+' beats '+player)
computer_point+=1
print("Player:",player_point)
print("Computer:",computer_point)
Explanation:
This imports the random module
import random
This prints the three possible selections
print("Rock\nPaper\nScissors")
This gets input for the number of points to win
points = int(input("Points to win the game: "))
This initializes the player and the computer point to 0
player_point = 0; computer_point = 0
The following loop is repeated until the player or the computer gets to the winning point
while player_point != points and computer_point != points:
The computer makes selection
computer = random.choice(['Rock', 'Paper', 'Scissors'])
The player enters his selection
player = input('Choose: ')
If both selections are the same, then there is a tie
if player == computer:
print('A tie - Both players chose '+player)
If otherwise, further comparison is made
elif (player.lower() == "Rock".lower() and computer.lower() == "Scissors".lower()) or (player.lower() == "Paper".lower() and computer.lower() == "Rock".lower()) or (player == "Scissors" and computer.lower() == "Paper".lower()):
If the player wins, then the player's point is incremented by 1
print('Player won! '+player +' beats '+computer)
player_point+=1
If the computer wins, then the computer's point is incremented by 1
else:
print('Computer won! '+computer+' beats '+player)
computer_point+=1
At the end of the game, the player's and the computer's points are printed
print("Player:",player_point)
print("Computer:",computer_point)
Genevieve is a student who attends classes at a campus downtown. She likes to study in the college's coffee shop, where she often accesses the Internet through the college's wireless network. Which network type is Genevieve using
Answer:
I'll let you make an educated guess off of this info! You always retain info better making an inference on a subject that you are having trouble with!
Explanation:
There are four types of wireless networks -- wireless local area networks, wireless metropolitan area networks, wireless personal area networks and wireless wide area networks -- each with its own function.
wireless local area networkA wireless local area network (WLAN) is a wireless distribution method for two or more devices. WLANs use high-frequency radio waves and often include an access point to the Internet. A WLAN allows users to move around the coverage area, often a home or small office, while maintaining a network connection.
wireless metropolitan area networkA metropolitan area network (MAN) is a computer network that connects computers within a metropolitan area, which could be a single large city, multiple cities and towns, or any given large area with multiple buildings. A MAN is larger than a local area network (LAN) but smaller than a wide area network (WAN).
wireless personal area networkA PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. PANs can be used for communication among the personal devices themselves, or for connecting to a higher level network and the Internet where one master device takes up the role as gateway.
wireless wide area networkWireless wide area network (WWAN), is a form of wireless network. ... WWAN connectivity allows a user with a laptop and a WWAN card to surf the web, check email, or connect to a virtual private network (VPN) from anywhere within the regional boundaries of cellular service.

Marina's personal computer requires a password to get access.
Answer:
This is most definitely a good practice to safeguard personal information. This way, people wouldn't be able to access her computer easily, since it requires a code that only she would know. of course, there is the possibility that someone can just guess or hack into her computer, but that's why computers usually have you create a unique code that consists of uppercases, lowercases, numbers, special characters, etc which would be difficult to guess. it's a good protection for anyone who wants to safely keep their personal information from everyone else.
