SAM
enable computers on a network to communicate
hubs
it can't identify the source or intended destination of the information it's receive so it sends the info to all of the computers connected to it
hubs
work the same way as hubs but they can identify the intended destination of the information that they receive
switch
can send and receive information at the same time
switch
computer working devices that builds the connection with the other bridge networks which uses the same protocols
bridge
work at the data link layer of the osi model
bridge
have two physical lan into larger logical lan or two segments of the same lan uses same protocol
bridge
enable conputers to communicate and they can pass information between two networks such as between your home network and the internet
router
also called based station provide wireless access to a wired ethernet network.
Wireless Access Point
it plug into hub or wired router
Access Point(AP)
this enables computer and devices to connect to a wired network wirelessly
Wireless Access Point
allows multiple devices to be connected and managed in a efficient manner.
Patch Panel
Computer sounds, studios, television stations and a number of other systems use this to deal with components of electronic system
Patch Panel
surface mounted box used in a commercial and industrial building to cleanly attach network cables.
modular box
commonly used in structured network
modular box
it is attach networks cable to a modular box
face plate
a network peripheral for mounting network jack/connector into a keystone wall plate
network keystone module
used to generate or replicate a signal, and it's also used in transmission system to regenerate analog or digital signals distorted by transmission loss.
Repeater
frequently amplify the signal
Analog repeater
can reconstruct a signal to near it's original quality
digital repeater
it's an 8pin connection use for Ethernet network adapter
RJ-45
also called Registered Jack
RJ-45
a device that is used to test the strength and connectivity of a particular type of cable
network cable tester
also called krone tool it's a hand tool used to connect telecommunication and network wires to a patch panel,punch down block, keystone module or a surface mount box
puch down tool
device used to conjoin two pieces of metal by deforming one or both of item in a way that causes them to hold each other
crimping tools
tool designed to remove the protective covering (jacket) of a cable to expose the inner wires
wire stripper
it is also called face plate
keystone wall plate
