Communications Hardware Communications Hardware Computer communications are becoming more and more important as technology changes to include world wide networks like the Internet. Computer communications are primarily with other computers. This is accomplished through phone lines and through networks of computers. Modems make this communication possible.
Modems translate digital computer information into analog signals used over phone lines.
They can also work in the reverse order by translating analog signals from a phone line into a digital signal used by a computer. Modems are distinguished by the number of bits per second of information that they can transmit. Commonly used modems operate at 14,400 and 28,800 bits per second.
