1. Interneta vast computer network linking smaller computer networks worldwide.

Internet is a short form of the technical term internetwork.

Internet continued ...

2. Connectivity

1)Cable Connection2)Wireless Connection3)Fiber connection

3. PPPoE Abbreviation of Point-to-Point Protocol Over Ethernet Works in dial-up basis. Authentication purpose

- username- password- mac-address

Internet access over DSL lines using Ethernet.

4. Router

• Layer 3 Device commonly used at user end.Eg: netis ,tplink

• Used to connect the internet.• Works on the basis of algorithm.• Secure

-protection against hacking• Advantages

- multiple connection- wireless connectivity- user defined access , b/w manage

5. ONU/ONT(Wifi and non-wifi) device

• Optical Network Terminal / Optical Network Unit

• LOS = Loss Of Signal• PON = Passive Optical

Network• LAN ports = 4 (LAN 2 is

for future IPTV use• USB port

6. FTTHFeatures:- Allows service providers to deliver more capacity to carry bandwidth- cost effective way- Future Proof technology- ONT device compulsory at client's end.- Scalable- unlike copper does not suffer from decreasing performance over distance.Abbreviation for Fiber To The Home

7. Bandwidth

Bit rate per secondSynonym for capacity or ability.Measured in bits per secondeg: message = 1000 bps voice = 56 kbps video (480p) = 1 mbps One of the network performance factors.

8. KBps Vs. kbps

KBps = Kilo Byte per secondKbps = kilo bits per secondKBps = 0.1220703125 * kbpsMeasure of data transfer speeds: KBps1 KBps = 1024 bytesMeasure of data transfer speeds: kbps1 kbps = 1000 bits

KBps Vs. kbps continued ...

512 KBps KBps is used in file size occupancy in hard disk drive.

512 kbpskbps is used in data transfer speed over network.

ISP bandwidth and Download speed

9. Cable Vs. FTTH

FTTH has minimum operating cost, minimum point of failure, distance independent signal strength,scalability, high speed and other advantage over cable InternetCable Internet uses RJ-45 port whereas FTTH uses Fast Connector.

10. Fast Connector
