Final answer:
The major difference between LTDWs and RTDWs is their physical location, with LTDWs being close to the server or computer and RTDWs being at a distance, accessed through a network connection.
Step-by-step explanation:
The major difference between the local terminal display workstation (LTDW) and the remote terminal display workstation (RTDW) lies in their physical location. A local terminal display workstation is usually situated in close proximity to the server or computer it is connected to, often within the same physical location such as an office or datacenter. In contrast, a remote terminal display workstation is located at a distance from the server or computer it connects to and access is typically achieved via network connections.
While screen size, connection speed, and operating system can vary between different workstations regardless of whether they are local or remote, these are not what primarily distinguishes LTDWs from RTDWs. Instead, it is the location relative to the server or main computer and the implications this has for access and use that serves as the key point of differentiation.
