yes/no
which protocol transmits data from a web server to the client?
HTTP
Fiber optic is one
network media
What network type is most commonly associated with your home environment?
LAN
What is a node?
Any networked device
Type of topology where all the computers are connected to each other along a single connected cable
Data moves from computer to computer; each looks to see if the data is addressed to them.
Bus topology
which protocol transfers files?
FTP
Used to pair an IP address to an identifier more easily remembered.
DNS
What network type is characterized by combining multiple LANS in a single geographical area?
MAN
What is a host?
An actual computer on the network
Each computer is connected in a "daisy chain", where there is no single start point. Data moves from one device to the next to see if it is addressed to it.
Different than bus, where all devices get the data at once.
Ring Topology
Which protocol transmits using IPs?
TCP
A logical division within a network
subnet
What network type could be characterized by UDP transmissions vs TCP/IP
PAN
What is the primary benefit of a network?
centralized storage of data
All devices are connected to a central point. Data is sent to this point and then forwarded to the correct device
Star
What protocols are used to send email?
SNTP and POP3
A networked host that does not have local storage
thin-client
What network type is characterized by wireless signals?
WLAN
A network that is primarily self-contained within an organization or other entity. Commonly having access to the outside world via a centralized gateway.
Intranet
All devices are connected to every other device on the network through a direct connection.
Mesh
network protocol used to securely transfer data using certificates
HTTPS
Used to secure communication between two computers
SSL
Secure Socket Layer
What network type is characterized by multiple LANs and/or MANs?
WAN
On any given network, each device has an address. This is used to simplify the addressing of packets to any given device by hiding the network portion of the address.
