WHATS THE DEAL WITH AIRLINE MAYONNAISE?z

I’M A WAY OLD POST THAT CHRIS EDITED ON 11/12/15.

the handshake.... explained!

modem noise + you’ve got mail

[modemsrock]

I mean i guess this is a thing...

56k modem sound

[modemsrock]

The stuff i am discovering in the process of making this is real ridiculous.

MODEM: Pshhhkkkkkkrrrrkakingkakingkakingtshchchchchchchchcch*ding*ding*ding"

COMPUTER: Hello this is computer.

I Used a 56K Modem for a Week and It Was Hell on Earth

In 1998, the year the first 56K modem was available for purchase, I was in the 8th grade.

This guy is mad about modems.

Boop beep bop beep boop bop beep boop ppprrrrrrrrrrrrrrttttttt prrt eet prtt eeeeeeeeeeeeeee prrrrrrrrrrrrrrrrtttt grrrr wee ooo wee ooo wee ffffffffffffffffffffffffffffff fffffffffffffffff

A modem.

From 2400baud to 56k, all things modem

A modem (modulator-demodulator) is a device that modulates signals to encode digital information and demodulates signals to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used with any means of transmitting analog signals, from light emitting diodes to radio. A common type of modem is one that turns the digital data of a computer into modulated electrical signal for transmission over telephone lines and demodulated by another modem at the receiver side to recover the digital data.

Modems are generally classified by the amount of data they can send in a given unit of time, usually expressed in bits per second (symbol bit/s, sometimes abbreviated "bps"), or bytes per second (symbol B/s). Modems can also be classified by their symbol rate, measured in baud. The baud unit denotes symbols per second, or the number of times per second the modem sends a new signal. For example, the ITU V.21 standard used audio frequency shift keying with two possible frequencies, corresponding to two distinct symbols (or one bit per symbol), to carry 300 bits per second using 300 baud. By contrast, the original ITU V.22 standard, which could transmit and receive four distinct symbols (two bits per symbol), transmitted 1,200 bits by sending 600 symbols per second (600 baud) using phase shift keying.
