LAC, or Local Area Connection, refers to a network connection that allows devices within a limited geographic area, such as a home, school, or office, to communicate with each other. This type of connection typically uses wired or wireless technologies to enable data sharing and resource access among connected devices. In the context of computing, LAC can also refer to Link Aggregation Control, a method that combines multiple network connections to increase bandwidth and provide redundancy. This ensures a more reliable and faster network experience, especially in environments with high data traffic.
