We can pass. telnet command and specify the host ip and port to connect``Memcached`` service.

1.4.1. Grammar

telnet HOST PORT

In the command HOST and PORT to run Memcached the IP and portof the service.

1.4.2. Example

The following example shows how to connect to the Memcached service andexecute a simple set and get orders.

For this example Memcached the host of the service is 127.0.0.1 (native) and the port is 11211.

telnet 127.0.0.1 11211

Trying 127.0.0.1...

Connected to 127.0.0.1.

Principles, Technologies, and Methods of Geographic Information Systems  102

In recent years, Geographic Information Systems (GIS) have undergone rapid development in both theoretical and practical dimensions. GIS has been widely applied for modeling and decision-making support across various fields such as urban management, regional planning, and environmental remediation, establishing geographic information as a vital component of the information era. The introduction of the “Digital Earth” concept has further accelerated the advancement of GIS, which serves as its technical foundation. Concurrently, scholars have been dedicated to theoretical research in areas like spatial cognition, spatial data uncertainty, and the formalization of spatial relationships. This reflects the dual nature of GIS as both an applied technology and an academic discipline, with the two aspects forming a mutually reinforcing cycle of progress.
