Ghella [55]

Answer:

import random

randomlist = []

for i in range(0,20):

n = random.randint(-29,30)

if n < 0 :

n = 100

randomlist.append(n)

print(randomlist)

Explanation:

The random module is first imported as it takes care of random. Number generation.

An empty list called randomliay is created to hold the generated random integers.

Using a for loop, we specify the range of random numbers we want.

Inside the for loop ; we attach our generated random integer which will be in the range (-29 to 30) in a variable n

For each n value generated, if the value is less than 0( it is negative, since all the values are integers), replace the value with 100.

Which of the following is true of how packets are sent through the Internet?
astra-53 [7]

Answer:

It is A: Packet metadata is used to route and reassemble information travelling  through the internet.

Explanation:

Step 1: The Internet works by chopping data into chunks called packets. Each packet then moves through the network in a series of hops. Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee

Step 2: Entering the network

Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee.

Step 3: Taking flight

The next hop delivers the packet to a long-haul provider, one of the airlines of cyberspace that quickly carrying data across the world.

Step 4: BGP

These providers use the Border Gateway Protocol to find a route across the many individual networks that together form the Internet.

Step 5: Finding a route

This journey often takes several more hops, which are plotted out one by one as the data packet moves across the Internet.

Step 6: Bad information

For the system to work properly, the BGP information shared among routers cannot contain lies or errors that might cause a packet to go off track – or get lost altogether.

Last step: Arrival

The final hop takes a packet to the recipient, which reassembles all of the packets into a coherent message. A separate message goes back through the network confirming successful delivery.

_________ media must be downloaded in its entirety to the user's computer before it can be heard or seen
gladu [14]

Answer:

Downloadable

Explanation:

Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.

Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.

In Computer science, a downloadable media must first be downloaded in its entirety and saved to a user's computer before it can be played, heard or seen.

For example, for an end user to listen to a song hosted on a particular website, he or she must first of all download the song in its entirety and have saved on a computer system before it can be seen, played and listened to. Also, other downloadable media such as videos, animations, texts, etc., must be downloaded before they can be accessed or used by an end user.
