A base-16 number system that uses sixteen distinct symbols 0-9 and A-F to represent numbers from 0 to 15.

The Luka Is Best System, I mean, Please!

A predication made by Gordon Moore in 1965 that computing power will double every 1.5-2 years, it has remained more or less true ever since.

Luka's Law of Interplanetary Motion

An Internet attack that causes a server to crash by making repeated requests to the same IP address:

DDoS (Distributed Denial of Service)

DNS (Domain Name System) Hijacking

Protocol that breaks data down into packets and addresses them with source and destination information

A DNS attack in which numerous pings are made to the same IP, causing it to crash

Protocol used by the World Wide Web. It describes how messages are formatted and interchanged, and how web servers respond to commands.

Protocol that provides reliable, ordered, and error-checked delivery of a stream of packets on the internet

The world is currently in a transition to using IPv6, a newer version of the IP protocol that uses 128-bit addresses instead of 32-bit addresses used by IPv4. What is the main problem that IPv6 was created to solve?

32-bit addresses could not ensure that every internet-connected device can receive a unique IP address

IPv6 will allow problems with IPv4's address hierarchy to be resolved

32-bit addresses could not accommodate the increased size and amount of data traveling on the Internet as it has grown in popularity

IPv4 proved unreliable in some cases where network redundancy could not be ensured

Which of the following statements about IP addresses is NOT true?

There are no rules or guidelines for creating a new IP address

Each IP address has a network previx and may have various subnet and interface IDs

Each of the octets in an address can be any number between 0 and 255

IP addresses may have prefixes to identify which routers or subnets the address belongs to

Which of the following statements about packets is true?

None of these statements are true.

Packets must be sent in order so they can be reassembled at the end host.

Packet switching results in a sustained, single connection between two hosts.

All packets must pass through a centralized router to be verified.

Why are parameters useful when programming?

Parameters allow for more flexible, generalized behaviors in functions.

Parameters determine the number of times the function will run.

Parameters are useful for teams of programmers because they help define the boundaries of the problem they are trying to solve.

Parameters change the order of operations within a function.

Which of the following statements about abstraction is true?

Abstraction reduces information and detail to facilitate focus on relevant concepts.

Abstraction requires users to understand the low-level details of a system.

Abstraction increases the run-time complexity of a program.

Abstraction compresses a program file to reduce file size.

A question to which there are only two possible answers.

A type of computer that forwards data across a network

A message that can only be one of two possible values.

A number assigned to any item that is connected to the Internet.

A type of computer that forwards data across a network

Transmission capacity measure by bit rate

A type of computer that forwards data across a network

documents are how standards and protocols are defined and published for all to see on the IETF website.

A preliminary sketch of an idea or model for something new. It’s the original drawing from which something real might be built or created.

Which of the following is an example of abstraction?

Writing a function for code you repeat often

Using logic symbols like < and >

Numbers are converted from one base to another

11. Under which of the following conditions is it most beneficial to use a heuristic approach to solve a problem?

(C) When the problem cannot be solved in a reasonable time and an approximate solution is acceptable

(A) When the problem can be solved in a reasonable time and an approximate solution is acceptable

(B) When the problem can be solved in a reasonable time and an exact solution is needed

(D) When the problem cannot be solved in a reasonable time and an exact solution is needed

21. Which of the following algorithms require both selection and iteration? Select two answers.

(B) An algorithm that, given a list of integers, displays the number of even integers in the list

(C) An algorithm that, given a list of integers, displays only the negative integers in the list

(A) An algorithm that, given two integers, displays the greater of the two integers

(D) An algorithm that, given a list of integers, displays the sum of the integers in the list

Which of the following most accurately describes Moore's Law:

Moore's Law is the observation that computing power tends to double every two years

Moore's Law describes a relationship of boolean logic statements involving AND and OR

Moore's Law is the principle that one should assume that any traffic on the Internet is insecure

Moore's Law explains why cracking modern cryptography is a "computationally hard" problem
