Domain Name
A website name; the part of the URL following www.
Domain Name System (DNS)
A global and highly distributed network service that resolves
strings of letters, such as a website name, into an IP address
Ethernet cable
It lets you physically connect to the network through a cable
Fiber optic cable:
Fiber optic cables contain individual optical fibers which are tiny tubes made of glass about the width of a human hair. Unlike copper, which uses electrical voltages, fiber cables use pulses of light to represent the ones and zeros of the underlying data
Globalization
The movement that lets governments, businesses, and organizations communicate and integrate together on an international scale
Hubs
Devices that serve as a central location through which data travels through
HTML
Hypertext Markup Language
Websites are text documents that we format with HTML
Internet

Internet Corporation for Assigned Names and Numbers ( ICANN)
Where website names are registered
Internet of Things (IoT)
The concept that more and more devices are connected to the internet in a smarter fashion such as smart thermostats that turn off the air conditioner when you leave and turn it on when you come back
Internet Protocol version 4 (IPv4)
An address that consists of 32 bits separated into four
groups
- 4 bytes in an IPv4 address.
- There are 256 available values in a byte with decimal values ranging from 0 to 255.
Internet Protocol version 6 (IPv6)
An address that consist of a 128 bits, four times the amount that IPv4 uses
Internet service provider (ISP):
A company that provides a consumer an internet connection
IP address
The most common protocol used in the network layer, used to helps us route information
MAC address:

The interconnection of computers
Just need 2 computers
Network Address Translation (NAT)
A mitigation tool that lets organizations use one public IP
address and many private IP addresses within the network
Networking
Managing, building and designing networks
Networking protocols
A set of rules for how we transfer data in a network
Network stack
A set of hardware or software that provides the infrastructure for a computer
Router
A device that knows how to forward data between independent networks
A router connects devices together and helps direct network traffic.
A router utilizes network protocols to help determine where to send data packets.
Server logs
Text files that contains recorded information about activities performed on specific web server in a defined period of time
Server
Devices that provide data to other devices that request that data, also known as a client
Switches
Devices that help our data travel
Transfer Control Protocol (TCP)
A protocol that handles reliable delivery of information from
one network to another
The TCP/IP protocol allowed computers to share information outside their network, which contributed to the Internet as we know it today.
Uniform Resource Locator (URL)
A web address similar to a home address
Wanna-Cry Attack
A cyber attack that started in Europe and infected hundreds of thousands of computers across the world
Wireless networking (Wi-Fi)
Networks you connect to through radios and antennas
