What/How About Our Home Network is?
by Teacher Phaitoon Yaemprasuan : occupatech@gmail.com
I have known from students of my computer classes that the Internet connection at their homes is of TOT provider. Yes, my internet service provider (ISP) is TOT too. What/how is my home network? The modem-router is the main device of the network because it plays many roles as of the followings : -
1) to simulate itself like a server computer
2) to act as a hub/switch of the wired connection
3) to be an access point sending packets of the wireless connection
4) to play as an ADSL modem connecting Internet
5) to be a router managing the how-to connect to other devices
Be sure, most of our home network is hybrid. One is wired while another is wireless. Although a home network is not complex, but its system is so smart and its Internet connection is so clever with the ADSL technology. The superstar is a "modem-router", the genius device.
UTP : Unshielded Twisted Pair cables are so common in any computer rooms e.g. classroom102 of our school. The UTP cable is caped with a connector which is called RJ-45. The RJ-45 connector will be inserted into the LAN port of any Ethernet card/router/switch/hub. (The RJ-11 connector of the phone line is smaller than RJ-45).
What is ADSL? (www.wikipedia.org) : It is "Asymmetric Digital Subscriber Line" technology. This is a data communications technology that enables faster data transmission over copper telephone lines than a conventional modem can provide. (Modem is a device that manages the joint communication between the phone and the computer.)
Another one I would like to refer to is "protocol". What is it? A protocol is a system of digital message formats and rules for exchanging those messages in or between computing systems and in telecommunications. And in our network we use the TCP/IP (comes from "Transmission Control Protocol and Internet Protocol). Now Thailand uses IPv4 protocol, but Thai government by Prime Minister Yingluck Shinawatra is going to change the Internet protocol of the country with another version, IPv6 protocol, which has more capacity and efficiency of transmission.
Because each computer of the network has its own unique "IP-address", what/how is it? As I have just told you (see, first paragraph) that the modem-router simulates itself like a server computer, sure its IPaddress must be static, e.g. (IPv4) 192.168.2.1, 192.168.1.1, 192.168.0.1 etc. , on the other hand it lets the other connected computer the dynamic/automatic IPaddress. Yes, the modem-router of the home network is the gateway to Internet.
