In today’s technologically advanced world, computers are often used for data communication. The phrase “data transmission” can refer to many things, but in its most basic definition, data transmission is the physical transfer of data over a communication channel. Specifically, data transmission in information technology relies on computer networking equipment.
Data Transmission with Modems
A modem uses an analog signal to encode digital information and transmit it. Modems make it possible for digital microcomputers to communicate across analog telephone lines. Today, modems are commonly used in computers and in fax machines.
Data Transmission with Local Area Networks (LANs)
A local area network (LAN) is a high-speed data network that is used to cover a small geographic area. Typically found in office environments, LANs connect workstations, personal computers, printers and other devices. There are many advantages of using LANs, including:
- Shared access to devices and applications
- Simplified file exchanging between connected users
- Quick communication between users via email and other applications
Data Transmission with Wide Area Networks (WANs)
A wide area network (WAN) differs from a LAN because it can cover a larger geographic area. Many businesses and government offices today use WANs to transfer data to employees, clients, suppliers and buyers in various geographic locations. It’s a modern technology that helps businesses carry out day-to-day activities regardless of location.
