List and briefly explain some error-prevention techniques.?

What will be an ideal response?

?You can prevent the occurrence of many types of transmission errors by applying proper
error-prevention techniques, including those listed below:
* Install wiring with the proper shielding to reduce electromagnetic interference and crosstalk.
* Use telephone line conditioning or equalization (provided by the telephone company), in which
filters are used to help reduce signal irregularities. For an additional charge, the telephone company
will provide various levels of conditioning to leased lines. This conditioning provides a quieter line,
which minimizes data transmission errors.
* Replace older equipment with more modern, digital equipment; although initially expensive, this
technique is often the most cost-effective way to minimize transmission errors in the long run.
* Use the proper number of digital repeaters and analog amplifiers to increase signal strength, thus
decreasing the probability of errors.
* Observe the stated capacities of a medium, and, to reduce the possibility of errors, avoid pushing
transmission speeds beyond their recommended limits.
