2. Firewalls

that prevent exterior
invades to a computer
network in the
organization or
computer that is
installed such system.
● In many cases,it is
installed to computer
as software and
used.
3. Powerline Ethernet
Bridges
● A quick way to extend a
local network into another
room via the building's
electrical system.
● .A short Ethernet cable
from the network router or
switch plugs intoone of
the bridges.
● Powerline bridges are
typically HomePlug
devices.
4. Network Address Translation
(NAT)
● NAT is technology
that some computers
share same global IP
adress in companies
that are connected to
the internet.
● There are times when
application don't
operate normally.
5. IP Routers
● IP routers is IP
address used in the
lookup.IP(Internet
Protocol)routers
require very fast
routing table lookup
for incoming IP
packets.
● IP routers are link
speeds,router
throughput,and packet
forwarding rates.
