In computing and especially computer networks, lag is a symptom where result of an action appears later than expected. While different kinds of latency are well defined technical terms, lag is the symptom, not the cause. Look up lag in Wiktionary, the free dictionary. ...

A computer network is an interconnection of a group of computers. ...
Latency is the time taken for a packet of data to be sent from onetime for encoding the packet for transmission and transmitting it, the time for that serial data to traverse the network equipment between the nodes, and the time to get the data off the circuit. This is also known as "one-way latency". A minimum bound on latency is determined by the distance between communicating devices and the speed at which the signal propagates in the circuits (typically 70-95% of the speed of light). Actual latency is much higher, due to packet processing in networking equipment, and other traffic. Latency is a time delay between the moment something is initiated, and the moment one of its effects begins. ...
In computer networking and telecommunications, packet switching is a communications paradigm in which packets (messages or fragments of messages) are individually routed between nodes, with no previously established communication path. ...
While strictly every packet experiences lag, the term lag is used to refer to delays noticeable to the user. Latency is directly related to the physical distance that data travels. Thus the time taken for a packet to travel from a computer server in Europe to a client in the same region is likely to be shorter than the time to travel from Europe to the Americas or Asia. But protocols and well written code that avoid unnecessary data transmissions are less affected by the latency inherent in a network. Modern corporate networks have devices to cache frequently requested data and accelerate protocols, thus reducing application response time, the cumulative effect of latency. In information technology, a server is an application or device that performs services for connected clients as part of a client-server architecture. ...

In computing, a client is a system that accesses a (remote) service on another computer by some kind of network. ...
