networking basics Flashcards
a group of computers that shares information through their interconnections is called a
network
the 4 components that make up a network are
host
transmission media
network interface
protocols
define transmission media
a path for electrical signals between devices
network interfaces are designed to
send and receive a electrical signal
the rules used to describe how hosts communicate and exchange data on a network is called
protocols
a logical subdivision of a ip network is called a
subnet
the process of connecting different networks by using intermediary devices such a routers and switches
internetwork
this topology(s) uses a hub
bus, star, and ring
this topology(s) be used with a hub or a switch
star
this topology exists when there are multiple paths between any two nodes on a network
mesh
it is used to connects a host to the network medium
network adapter
wires, fiber optic, and radio waves are classified as
networking mediums
it is responsible for converting digital data into analog waves
a modem
the conversion of digital data into an analog wave is called
modulation
the conversion of a analog wave into digital data is called
demodulation
it is used to convert digital data into digital signals to be sent on the medium
transceiver
what is a MAC address
a 48 bit unique hexadecimal identifier burned into every network interface’s ROM
The first half (first 6 digits) of the MAC address is assigned to
manufacturer.
a central device in a wired or wireless local area network (LAN) is called a
switch or a hub
a network device that forwards data packets between computer networks
router
