You know you are on a secure site if you see this in front of the site's address:

• HTTP://
• HTTPS://
• WWW.
• UPC://

A global system of interconnected computers, servers and mainframes

• A supercomputer
• URL
• The internet
• AOL

The address for s single file on the internet is called it's:

• HTTP
• ISP
• HTML
• URL

Which of the following statements are true about routers and routing on the Internet. Choose TWO answers.

• Protocols ensure that a single path between two computers is established before sending packets over it.

• Routers are hierarchical and the "root" router is responsible for communicating to sub-routers the best paths for them to route internet traffic.

• A packet traveling between two computers on the Internet may be rerouted many times along the way or even lost or "dropped."

• Routers act independently and route packets as they see fit.

The Internet Engineering Task Force (IETF) defines the protocols and standards for how the Internet works. The members of the IETF are:

• An international coalition of government agencies who oversee the internet in other countries

• A collection of the leaders of the Tier 1 Internet service providers

• A loosely organized collection of citizens and engineers

• Political leaders and heads of state

What is the best explanation for why digital data is represented in computers in binary?

• The binary number system is the only system flexible enough to allow for representing data other than numbers

• It's easier, cheaper, and more reliable to build machines and devices that only have to distinguish between binary states

• It typically takes fewer digits to represent a number in binary when compared to other number systems

• It's impossible to build a computing machine that uses anything but binary to represent numbers

What is the 5 bit binary number for the decimal 7

• 111

• 01011

• 00111

• 1110

What is the minimum number of bits you would need to encode 27 unique characters?

• 2 bits

• 3 bits

• 5 bits

• 6 bits

Number systems with different bases such as binary (base-2) and decimal (base-10) are all used to view and represent digital data. Which of the following is NOT true about representing digital data?

• At one of the lowest levels of abstraction, all digital data can be represented in binary using only combinations of the digits zero and one.

• The same value (number) can have a different representation depending ont he number system used to represent it

• Groups of bits can be used to represent abstractions, including but not limited to numbers and characters

• Some large numbers cannot be represented in binary and can only be represented in decimal
