It was the first generation of an automated telephone exchange used for routing calls from one line to another. Strowger was the first to implement electromechanical switches which removed the need for an operator to manually connect the telephone lines together.

What is the Algorithm for exchanging values of two variables?
There are three primary algorithms to exchange the values of two variables. Exchange with Temporary Variable temp = a; a = b; b = temp; Exchange Without Temporary Variable Using Exclusive Or a = a ^ b; b = b ^ a; a = a ^ b; Exchange Without Temporary Variable Using Arithmetic a = a + b; b = b - a; a = a - b;
Bateria exchange genetic material?
Bacteria exchange genetic material, in the form of plasmids, through conjugation. Conjugation is achieved when a pili from once cell attaches to the cell wall of another cell..

How do you design a 10000-line telephone exchange using a Strowger system?
The famous Strowger electromechanical switches, first the 2000-type in the 1930s and the 4000-type in the 1960s, were the basis of telephone exchanges. However they were slow, working in real time with 0.1-second pulses from the subscriber's dial, and consumed a lot of power, plus they needed a lot of maintenance. One exchange I worked in had about 80,000 lines and used about 100 kW of power at 50 volts in the morning busy-hour. And all exchanges had to have a battery to keep them going for 24 hours in an emergency. A 10,000-line exchange can't be explained in ten lines with such a wide variation in readers' prior knowledge.
When was the automatic switchboard invented?
In 1891, American Almon B. Strowger patented the first automatic switchboard
What city and state had the first telephone exchange?
La Porte, Indiana, November 3rd 1892.The equipment was a Strowger, electromechanical system. Invented by Almon Brown Strowger.His day job was an undertaker, but also inventor. Fed up with loosing trade to competitors, because of interception by human telephone operators, he devised and patented the first automatic system.It worked by sending pulses down the phone line, which moved a mechanical switch at the exchange, selecting one of up to 99 lines. later designs involved the rotary dial, to produce the pulses.
Step by step switching technique?
step by step switch (also called strowger after its inventor) uses step relays capable of assuming ten separate levels,representing a decimal digit.
