Question

Short note on telex service.​

Answer 1

Explanation:

The telex network was a customer-to-customer switched network of teleprinters similar to a telephone network, using telegraph-grade connecting circuits for two-way text-based messages.[1] Telex was a major method of sending written messages electronically between businesses in the post-World War II period. Its usage went into decline as the fax machine grew in popularity in the 1980s.

The "telex" term refers to the network, and sometimes the teleprinters (as "telex machines"),[2] although point-to-point teleprinter systems had been in use long before telex exchanges were built in the 1930s

Answer 2

Telex, international message-transfer service consisting of a network of teleprinters connected by a system of switched exchanges. Subscribers to a telex service can exchange textual communications and data directly and securely with one another.
