    Study Notes

    • DSL (Digital Subscriber Line) internet connectivity requires proximity to a central office (CO), with speeds decreasing as distance increases and maximum limit around 10,000 feet.

    • Download speed: 52 Mbps; upload speed: 16 Mbps, but these numbers can vary.

    • Dial-up connections (using analog voice telephone lines) are much slower (56 kbps or compressed up to 320 kbps), making them difficult for mass usage.

    • Fiber internet is increasingly being used at home, offering high-speed networking, increased bandwidth, and capability for multiservice delivery (voice, video, data).

    • Fiber provides HD channel connectivity and data transfer to the cloud.

    • Satellite networking allows communication directly to a satellite for internet access, with average speeds of 50 Mbps download and 3 Mbps upload, but high latency and vulnerability to rain interference.

    • ISDN (Integrated Services Digital Network) is an older type of internet connectivity with two versions: Basic Rate Interface (BRI) and Primary Rate Interface (PRI).

    • BRI consists of two 64 kbps bearer channels and a 16 kbps signaling channel.

    • PRI is delivered over a T1 or E1 connection and supports up to 23 or 30 bearer channels and a signaling channel.

    • PRI is commonly used for voice communications, especially for businesses not converting to Voice over IP (VoIP).

    • Cellular networks enable internet access from almost anywhere.

    • DSL (Digital Subscriber Line) internet connectivity requires proximity to a central office (CO), with speeds decreasing as distance increases and maximum limit around 10,000 feet.
