Data
The most basic form of data representation.
What is binary?
The three abstractions required for the CPT
What is sequencing, selection, and iteration
A systems ability to transmit data even with the presence of a broken connection
What is fault-tolerance?
This is the end of year project that all APCSP students must complete
What is the CPT? (Create Performance Task)
Pieces of data are stored in these and sent in any order to another location?
What is a packet?
This amount of bits can represent numbers 0-511
What is 9 bits?
A solution that is used when there is no answer that can be provided within reasonable constraints
What is a heuristic solution?
A method that uses a program to record keystrokes without a users knowledge?
What is keylogging?
An error that produces an output that in not desired by the programmer
What is a logic error?
Controls the method by which messages are broken down into packets and then reassembled when they reach their final destination
What is TCP?
Measured at regular intervals to convert into binary data.
What is analog data?
The two values needed to calculate algorithmic efficiency.
How is speedup calculated?

This aspect makes it so that a parallel computing system will function more efficiently than a sequential computing system.
An object or product created utilizing some form of computing device
What is a computational artifact?
This protocol is best suited for calls or communication that utilizes fast data transfer
What is UDP

A binary search method is used to search a list of values from 0-99. The list has been pre-sorted. How many iterations would it take to find the number 82?
7 iterations
What is the maximum amount of values that can be represented by the quotient of the number of bits in an IP V.6 address divided by the number of bits in an IP V.4 address?
15 values
