AP COMPUTER SCIENCE A EXAMPREP
QUESTIONS AND SOLUTIONS COMPLETE
PREPARATION SHEET
●● Prototype
Answer: 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.
●● Bit
Answer: A contraction of "Binary Digits". A bit is the single unit of
information in a computer, typically represented as 0 or 1.
●● Binary
Answer: A way of representing information using only two options.
●● Bandwidth
Answer: maximum transmission capacity of the device expressed
typically in metric multiples of bits per second
●● Bit Rate
Answer: The numbers of Bits that are conveyed or processed per unit of
time. EX: 8bits/per second.
,●● Latency
Answer: the amount of time it takes for a bit to travel from sender to
receiver
●● Protocol
Answer: A set of rules governing the exchange or transmission of data
between devices.
●● American Standard Code for Information Interchange (ASCII)
Answer: The universally recognized raw text format that any computer
can understand.
●● Code
Answer: To write instructions for a computer.
●● Requests for Comments (RFC)
Answer: Documents are how standards and protocols are defined and
published for all to see on the IETF website.
●● Internet
Answer: a tangible physical system that is made to move information
,●● IP Address
Answer: A number assigned to any item that is connected to the internet.
●● Packets
Answer: small chunks of information that have been carefully formed
from larger chunks of information for the purpose of transmitting
through a network
●● Router
Answer: A computer which receives messages travelling across a
network and redirects them towards their intended destinations based on
the addressing information included with the messages.
●● Transmission Control Protocol (TCP)
Answer: Provides reliable, ordered, and error-checked delivery of a
stream of packets on the internet. TCP is tightly linked with IP and is
usually seen as TCP/IP in writing.
●● Domain named system (DNS)
Answer: The internet's system for converting alphabetic names into
numeric IP addresses.
●● Hypertext Transfer Protocol (HTTP)
, Answer: Is the protocol used by the world wide web. It describes how
messages are formatted and interchanged, and how web servers respond
to commands.
●● Abstractions
Answer: Reducing information and detail to focus on essential
characteristics.
●● Server
Answer: A computer that awaits and responds to requests for data.
●● Client
Answer: A computer that requests data stored on a computer.
●● HTTPS
Answer: a protocol for secure communication over a computer network
which is widely used on the Internet.
●● Digital Certificate
Answer: an electronic document used to prove ownership of a public
key.
●● DDoS
