WorkstationWorkstationA powerful computer for massive tasks by

multiple remote users concurrentlyMulti-user multi-taskingMust be stable and equipped with high-end CPU

and memoryUNIX-like OS is most commonly used

Remote Computing by SSHRemote Computing by SSHSince multiple users log on to the workstation

simultaneously, every user should use their PC as the terminal and run their tasks through a protocol called SSH

In brief, we need two programs to log inPuTTY: The terminal programXming: The window server for running GUI

programs on workstation Both are freeware
