◉ 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.
Answer: pertaining to or being an incident in which a network of
computers floods an online resource with high levels of unwanted traffic
so that it is inaccessible to legitimate service requests
◉ HTTP Request.
