computing system
a group of computing devices that work together to solve a problem or provide a service
network
a computing system that links two or more computers together to share data
network adapter
a device that knows how to send and receive data across a network connection
ethernet cards
the standard network adapters used on most desktop computers
wireless network
a network which uses over-the-air signal for connections and does not require any wired connections
bandwidth
the amount of data you can push through a network connection over a given time
maximum transmission capacity
coaxial
the first type of cable used for networking, consisting of a solid copper wire surronded by insulation
twisted pair
cables containing up to 8 wires, wound together in pars to minimize electromagnetic interference, used for ethernet cables
baseband
a cable where bi-directional data is sent using digital signals that take up the entire bandwidth (or capability) of the cable
broadband
a cable where uni-directional data is sent in the form of an analog signal. more than one stream of data can be sent over the cable at one time
hub
a simple network device that connects computers together, broadcasting information to all connected device
switch
a smarter version of a hub, which is capable of sending information to a single recipient in a network
router
a device designed to pass information between multiple networks
gateway
the places in a system where two or more networks connect
modem
a device used to understand the particular type of network signal sent by an Internet Service Provider, and is often included in a home router
wireless access point
a device which acts as a hub or switch for all of the wireless devices connected to the network
internet
a huge global network of computer connected to one another
server
a computer that specializes in storing information or processing requests
client
a computer that will request data from server computers using an application or browser
internet service provider
a company that provides access to other services on the internet
IP address
internet protocol address a network address which allows one computer or device to communicate with other computers or devices
routing
selecting the bets path for data packets to travel across a network
IPv4
an address that contains four individual numbers betwen 0 and 255 that uniquely identify your computer on a network
IPv6
an address that contains 16 numbers in hexadecimal form, which allows many more addresses than IPv4
protocol
a language or method for sending data on the internet
open system connection
the internet standards that govern the protocols used i transmitting data
TCP/IP
this protocol is responsible for sending and receiving packets of data across the network
packet
a unit of data made into a single package that travels along a given network path
data stream
a group of related data packets sent across a network
transmission control protocol
highly reliable protocol that controls the way packets are sent and received on a network
reliability
a concept that says when one network component fails, the remining parts continue working as best they can
user datagram protocol
fast protocol that controls the way packets are sent and received on a network
world wide web
a giant collection of specially linked and formatted information organized into websites and pages tat you can view through your web browser
HTTP
hyper-text transfer protocol the language for sending web page data on the internet
file transfer protocol
the language for sending file data on the internet
post office protocol
a protocol that is used to download or receive ny messages that are waiting for you account
simple mail transfer protocol
a protocol that is used to send email from users to mail servers, or from one mail server to another
internet message access protocol
a newer protocol that is used to download or receive email messages
local area network
a similar network of computers in your home or office
scalability
the ability of a system to grow or shrink to meet new levels of demand
fault tolerance
a networks ability to continue uninterrupted communications despite the failure of one or more of its components
redundancy
the inclusion of extra components in a network that can be used in case other components fail
user datagram protocol
the goal is to send info quickly without worrying about accuracy. it sends all packets at once an doesn’t check if they all get through or arrive in the right order. this is useful in real life when split seconds matters more the correcting errors, like video-conferencing, live streaming and online gaming
lossless compression
reduces the number of bits stored or transmitted while guaranteeing complete reconstruction of the original data
lossy compression
significantly reduces the number of bits stored or transferred but only allow reconstruction of an approximation of the original data
bit
pair of options (1,0)
bit rate
the number of bits per second
latency
delay between actions
