6 COMPUTER NETWORKING HARDWARE: FUNCTIONS AND IMAGES PART 2
Continue the article I once posted yesterday about Computer Networking Hardware: Functions And Images Part 1 then I will share Computer Networking Hardware: Functions And Images Part 2 again, see and watch
7. Access Point
If you know that the router has the same function as the access point, then what is the advantage of the access point? The access point has the advantage, the price is cheaper than the router, and its application is much simpler. Access points are only used to transmit wireless signals received from routers or broadband to create a WLAN network or wireless area network.This function is much simpler when compared to routers, which have very complex and many functions.

The distinction of Access Point
a. The price is cheaper
b. Easier treatment
c. Can connect directly with router or broadband
d. Already support the use of wireless (which currently access point jga often we are familiar with the term hotspot)
f. Can be used in small to medium room
8. Cable
When talking about the network, surely we must have cable. Yes, the cable serves to bring data packets from the server to the client, of course, in a network that is not a wireless network. Typically, the cable used is a type of UTP cable or Unshielded Twisted Pair, Coaxial, and also Fiber Optic cable. Of course, the use of cabling in computer networks is very efficient, especially when you want to build a local interface, because the cost is cheaper than with wireless devices.
Lack of cable usage

| Network Cable |
a. Installations that tend to be complicated, because it must consider the location of safe placement of the cable
b. Need cable in large quantities
9. NIC or Ethernet Card
NIC stands for Network Interface Card, which is a card - also known as ethernet card - that plays an important role in the network of composers.Ethernet card is a network card that is embedded in the computer, which will make a computer capable of connecting to the LAN network.

Ethernet card function
With this ethernet card, then each computer can be connected to each other in the network by using a cable connection. However, it may be that ethernet cards are now used, even though they are one of the standard protocols in a computer system. This is neither nor is it because of the invention of wireless technology that is more practical and also easy to apply. For more details about ethernet, you can read the benefits of LAN card and also the function of LAN Card.
10. Modem
The next hardware that is an important device in a computer network is a modem.A modem is an extension of modulator and demodulator. Literally, it means a modem is a two-way communication form in which the modem can process the change of digital signal data into analog, and they can change the signal back into digital the to be used in the computer.

Use of current modem
Currently, the development of the modem is much more rapidly, first, the modem is used to use Dial-up connection known as ADSL Modem. Currently, the modem is shaped USB, so easy to use. In addition, there is also a modem that has a function that is combined with the router, so that all modem functions, routers, and access points are in one tool only.
11. Connector
The connector is a device installed on each end of the network cable to connect the network adapter with the cable.Different types of network connectors must be adapted to the type and type of network cable used.
a. RJ-45 connector is used for UTP Cable

| Connector RJ-45 |
b. BNC / T connectors are used for Coaxial Cables
c. ST connectors are used for Fiber Optic Cables
12. Repeater
The repeater is a computer network hardware to amplify the signal if used at a great distance. With this repeater the network is not reachable by a considerable distance in a LAN, it can be developed and pulled some distance away and gained enough signal.
