AP COMPUTER SCIENCE PRINCIPLES:
INTERNET EXAM 2025/2026 QUESTIONS
AND ANSWERS 100% PASS.
What is a bit? - ANS a single unit of data that can only have one of two values (such as a 1 or
0)
What is a byte? - ANS Eight bits (e.g.10110101)
What is bandwidth? - ANS the transmission capacity of a system (measured by the amount of
data (measured in bits) that can be sent in a specific amount of time)
What is latency? - ANS time between the transmission and the receipt of a message
How can number storage limitation cause overflow errors? - ANS Certain programs limit how
many numbers they can store (e.g. if limit is 4 bits, then storage goes up to 1010). After a
number that is long enough goes over the limit, it causes overflow, which returns an overflow
error (e.g. infinity or NaN)
What are floating point numbers? - ANS a binary version of scientific notation. It's called
floating point because the decimal point "floats" to just after the first digit. (e.g.
2.1273647e+32)

, How can floating points lead to round-off errors? - ANS Floating points round off the last
digits of a infinite/large number, which can cause a rounding that might be incorrect when
manipulated (e.g. 1/3=0.3333, but when multiplied by 3, it states 0.99999 and not 1)
What does an ethernet cable use? What are its features? - ANS It uses electricity to send bits.
Best for close distances, but cheap and has potential signal loss
What does an fiber optic cable use? What are its features? - ANS It uses light to send bits.
Best for far distances, fast, and lower potential signal loss, but expensive and hard to work with
What is a web browser? - ANS An app used to access web pages
What is an URL? - ANS Uniform Resource Locator: an address for accessing specific web data
located on a server
What is a DNS server? - ANS Domain Name System server: a computer or computers hosting
data for other to access
What is HTTP? - ANS HyperText Transfer Protocol: language used to communicate between
web browsers and servers
What is HTML? - ANS HyperText Markup Language: language used to tell a web browser how
to make a page look
What two components does HTML decide seperately? - ANS (1) the text on the web page
(2) each seperate picture and video
(a seperate HTML code for every one of those)
What are the steps of accessing a web page? - ANS (1) Open web browser
(2) type in URL or other
(3) HTTP code [get () request] is sent to DNS
