Understanding internet connection
There are certain terms related to internet connection that you
need to understand…
Dial up connection:-
In simple terms, dial
up connection is a technique to get your computer access to
a LAN (Local Area Network) or WAN (Wide Area Network) via a telephone
line using modem. Types of dialup include dial up connection using
various types of modem like V.34 and V.90 or Integrated
Services Digital Network (ISDN). Dialup uses special-purpose
network protocols like Point-to-Point Protocol (PPP).
Modem is an acronym for "Modulator Demodulator."
Technically, a modem converts data for the purpose of computer
to computer communication. The modem converts analog form used
on telephone lines into the digital form used on computers and
vice versa. Standard 56K modems can transmit data at a maximum
rate of 56,000 bits per second (bps) or 56kbps. However, limitations
of the phone system translate to modem speeds much lower in practice.
In recent times, modems for cable and DSL service have come into
picture. They are also known as digital modems. The terminology
is misleading as modems all involve analog data transmission.
However, these modems have been designed to gain improved digital
support from the access provider's location. Cable and DSL modems
use broadband signaling techniques to achieve dramatically higher
network speeds than traditional modems.
Network performance measurement units:-
Network performance is measured in bits per second or Bytes per
second. There are various symbols used for them. When measured
in bits per second following units are used.
kbps :- one kilobit per second and equals to 1000 bits per second
mbps :- one megabit per second and equals 1000 kbps.
gbps :- one gigabits per second and equals 1000 mbps.
Sometimes the measurement is given in bytes per second (Bps).
In that case…
Kbps :- one kilobytes per second and equals to 1000 bytes per
Mbps :- one megabytes per second and equals 1000 Kbps.
Gbps :- one gigabytes per second and equals 1000 Mbps.
1. Analog modems support data rates up to 56 Kbps i.e. 56 kilobytes
per second. 2. Traditional broadband connections provide data
transfer rate from 10 Mbps to 100 Mbps.
There are certain other representations used such as: Kb/sec,
Kb/s, Mb/sec, Mb/s, Gb/sec, Gb/s
The broadband connection
is next step in evolution after analog modems. The broadband connection
is a type of transmission technique that carries several data
channels over a common wire. For example, DSL service combines
separate voice and data channels over a single telephone line.
In this technique, voice fills the low end of the frequency spectrum
and data fills the high end.
For a home internet user the term, "broadband" usually
refers to high speed
Internet access using this transmission technique. A broadband
connection is usually connected through DSL line or Ethernet
line which is common broadband Internet technologies. Cable modem,
broadband routers are network devices that support both DSL and
cable internet connection.
