Intro to Python Project Stem Unit 11 Test

Definition: The process of scrambling or changing a message to hide its original text.

• Encryption

• Cryptography

• Authentication

• Protocol

Answer explanation

Encryption is the process of scrambling a message to hide its original text, making it unreadable without a key. Cryptography is a broader field that includes encryption, while authentication and protocol refer to different concepts.

Term: Latency

• The process of scrambling or changing a message to hide its original text.

• A company that provides customers with internet access.

• The amount of time it takes for bits to travel from sender to receiver.

• The number of bits per second a system can transmit.

Answer explanation

Latency refers to the time delay in data transmission. The correct choice defines it as the amount of time it takes for bits to travel from sender to receiver, which is essential in understanding network performance.

Term: Cybersecurity

• The measures taken to protect a computer or computer system against unauthorized access or attacks.

• A network of networks, a tangible, physical system made to move binary information.

• The process of scrambling or changing a message to hide its original text.

• The maximum transmission capacity of a device, measured by bitrate.

Answer explanation

Cybersecurity refers to the measures taken to protect computer systems from unauthorized access or attacks, making the first choice the correct definition.

What is an Internet Service Provider?

• A) A company that provides customers with internet access.

• B) Rules governing the format of data sent over the internet or other network.

• C) A set of rules and standards used for communication.

• D) Rules governing the format of data sent over the internet or other network.

Answer explanation

An Internet Service Provider (ISP) is defined as a company that provides customers with internet access, making option A the correct choice. The other options refer to data communication rules, not ISPs.

Definition: An executable program that is installed, usually unintentionally, and harms a user and their computer. What is this definition referring to?

• A) Protocol

• B) Virus

• C) Worm

• D) Trojan

Answer explanation

The definition refers to a 'Virus', which is an executable program that can harm a user's computer, often installed unintentionally. Unlike worms or Trojans, viruses specifically replicate and spread by attaching to other programs.

Definition: Rules governing the format of data sent over the internet or other network. What is this definition referring to?

• The Internet

• Internet Protocol

• Network

• Transmission Control Protocol

Answer explanation

The definition refers to 'Internet Protocol' (IP), which establishes rules for data formatting and transmission over networks, ensuring that data packets are sent and received correctly.

The number of bits per second a system can transmit.

• Bandwidth

• Latency

• Protocol

• Bitrate

Answer explanation

Bandwidth refers to the maximum rate of data transfer across a network, measured in bits per second. It indicates how much data can be transmitted in a given time, making it the correct choice for this question.

Term: HTML.

• Tags that provides additional information about an element in HTML (color, size, font).

• An executable program that is installed, usually unintentionally, and harms a user and their computer.

• A network of networks. A tangible, physical system made to move binary information.

• Hypertext Markup Language, the markup language for documents designed to be viewed in a web browser.

Answer explanation

The correct answer is 'Hypertext Markup Language, the markup language for documents designed to be viewed in a web browser.' HTML is the standard language used to create and design web pages.

Term: CSS.

• An executable program that is installed, usually unintentionally, and harms a user and their computer.

• A language used for altering the appearance of a document written in HTML.

• The amount of time it takes for bits to travel from sender to receiver.

• The process of scrambling or changing a message to hide its original text.

Answer explanation

CSS stands for Cascading Style Sheets, which is a language specifically designed to style and alter the appearance of HTML documents. This makes the second answer choice the correct one.

What is the principle that Internet Service Providers should enable access to all content and applications regardless of the source, and without favoring or blocking particular products or websites?

• The measures taken to protect a computer or computer system against unauthorized access or attacks.

• The process of unscrambling a text to make it readable.

• The principle that Internet Service Providers should enable access to all content and applications regardless of the source, and without favoring or blocking particular products or websites.

• The process of scrambling or changing a message to hide its original text.

Answer explanation

The correct choice describes net neutrality, which mandates that Internet Service Providers must provide equal access to all content and applications without discrimination, ensuring a fair and open internet.
