Data Transmission Problems

Both hardware and software can cause data transmission problems.

All parts of a computer network must work correctly for it to function efficiently. If the hardware or software develops a glitch, you'll run into data transmission problems. Common causes include poor connections, configuration changes and a network with too much traffic.

Connection

Hard-wired networks depend on a solid connection between computers. Broken wires and worn connectors will interfere with data transmission. For wireless networks, radio signals can degrade performance and interference from metal obstructions can do so as well.

Configuration

A network depends on programs that route data between computers. The programs need detailed instructions about how the network works. If the network administrator or the user makes a mistake in setting the software's configuration, no data will get through.

Saturation

Increasing demands on a network, such as excessive downloads, will saturate its capacity, creating a traffic jam for everyone. The network administrator must keep track of the network's load and set aside enough capacity for all users.

Noise

Radio interference and electrical noise cause data transmission problems. If data arrives scrambled, computers will resend it. Eventually, good data will get through, but the retransmissions add to network traffic and slow it down.
