The document discusses various hardware devices used in network communications. A Network Interface Card (NIC) allows a computer to communicate over a network and access the network. A Wireless Network Interface Card (WNIC) provides wireless data transmission over a radio network. An internal modem is built into a stand-alone computer to transmit data over phone or cable lines, while an external modem is separate from the computer and mobile. A switch establishes connections between devices that want to communicate, and a hub contains multiple ports to connect LAN segments. A router connects multiple computers or routers and transfers data packets between networks, and a wireless access point connects wireless devices to form a wireless network and relay data to a wired network.

3.2.1.2:Function of the devices needed in network communications
Network Interface Card (NIC)
 A Network Interface Card is a piece
of computer hardware designed to
allow computer to communicate
over a computer network.
 Enables the computer to access the
network
Wireless Network Interface
Card (WNIC)
 A Wireless Network Interface
Card or WNIC is a network card
which connects to a radio-based
computer network.
 A network card that provides
wireless data transmission
INTERNAL MODEM
 A modem is a device that enables
a computer to transmit data over
telephone or cable lines.
 An internal modem only works
in stand-alone computers. It is
built into the computer.

2. [KPD 4046 TEACHING METHOD] HARDWARE REQUIREMENT
EXTERNAL MODEM
 A modem is a device that enables
a computer to transmit data over
telephone or cable lines.
 An external modem is separated
from the computer and is also
mobile.
SWITCH
 A switch understands when two
devices want to talk to each
other, and gives them a switched
connection.
 A common connection point for
devices in a network.
HUB
 Hubs are commonly used to
connect segments of a LAN.
 A hub contains multiple ports.

3. [KPD 4046 TEACHING METHOD] HARDWARE REQUIREMENT
ROUTER
 A router is a communications
device that connects multiple
computers or other routers
together and transmits data to the
correct destination.
 A router acts as a junction
between two or more networks to
transfer data packets among
them.
WIRELESS ACCESS POINT
 A wireless access point is a
device that connects wireless
communication devices together
to form a wireless network.
 Connects to a wired network and
can relay data between wireless
devices and wired devices.

4. [KPD 4046 TEACHING METHOD] HARDWARE REQUIREMENT
Match the devices to their function correctly.
NETWORK INTERFACE  A device that enables a computer
CARD (NIC) to transmit data over telephone
or cable lines.
 Only works in stand-alone
computers. It is built into the
computer.
 A device that enables a computer
WIRELESS NETWORK to transmit data over telephone
INTERFACE CARD or cable lines.
(WNIC)
 Separated from the computer and
is also mobile.
 A piece of computer hardware
designed to allow computer to
INTERNAL MODEM communicate over a computer
network.
 Enables the computer to access the
network
 A network card which connects
to a radio-based computer
network.
EXTERNAL MODEM  Provides wireless data
transmission
