2. BANDWIDTH WHAT IS BANDWIDTH?
Bandwidth is the rate at which data is transferred. It is the maximum amount of information that can be processed along a channel. Bandwidth is usually measured in ‘bits per second’. Bandwidth speeds are measured in kilobits per second (Kbps) and megabits per second (Mbps).

3. NARROWBAND What is narrowband?
Narrowband describes the telecommunications that carries voice information in a narrow band of frequencies. The term narrowband, more specifically, has been used to describe a specific frequency range for radio or mobile services, including paging systems, from 50 cps to 64 Kbps. It transmits a maximum of 34, 000 bits per second.

4. BROADBAND WHAT IS BROADBAND?
Broadband is a high bandwidth connection to the internet, also known as high-speed internet, which is faster and easier as the normal telephone as information can be downloaded and sent much quicker.
Broadband transmission speeds are:
256Kbps, 512Kbps, 1 Mbps, 2 Mbps, 8 Mbps and 24 Mbps.

5. VOICEBAND WHAT IS VOICEBAND
In electronics, voice band deals with the frequency range that a human can hear. It ranges from 20Hz to 20kHz.
In telephony, it means the frequency range that is normally transmitted by a telephone line, generally around 200Hz to 3600Hz.
