Binary Basics
This is the smallest unit of data in a computer.
What is a bit?
The smallest unit of a digital image.
What is a pixel?
This type of compression does not remove any information.
What is lossless compression?
The Internet is often called a network of these.
What are networks?
This protocol helps deliver packets to the correct destination.
What is IP?
The Internet's ability to continue working despite failures.
What is fault tolerance?
How many bits are in a byte?
What is 8?
Increasing this usually makes an image clearer.
What is resolution?
JPEG files commonly use this type of compression.
What is lossy compression?
A set of agreed-upon rules for communication.
What is a protocol?
This protocol reassembles packets and requests missing packets.
What is TCP?
Having multiple routes available for packets.
What is redundancy?
The decimal number represented by binary 11111111.
What is 255?
The process used to digitally capture sound.
What is sampling?
The main purpose of compression.
What is reducing file size?
Small pieces of data sent across a network.
What are packets?
This system converts website names into IP addresses.
What is DNS?
The ability of the Internet to grow and support more users.
What is scalability?
Convert the binary number 00001010 to decimal.
What is 10?
In regards to music. A higher sampling rate generally results in this.
What is better sound quality?
This type of compression may slightly reduce quality but creates smaller files.
What is lossy compression?
Devices that direct packets toward their destination.
What are routers?
This protocol is used to transfer web pages.
What is HTTP?
Why can packets still reach a destination if one path fails?
What is redundancy/fault tolerance?
Convert the decimal number 45 to binary.
What is 00101101?
A photo with more pixels will usually have this drawback.
What is a larger file size?
Name one advantage of lossless compression over lossy compression.
What is keeps all original data?
The type of system used by the Internet where packets may take different routes.
What is packet switching?
A student types google.com. Which protocol translates that name into an IP address?
What is DNS?
Name two characteristics that have helped the Internet become successful.
What are fault tolerance, scalability, redundancy, or open standards?
