This workshop focuses on analysis forces, communication tools, and network connectivity. Students and staff work on analysis plans before returning to NIKHEF. Utilize Telnet and FTP for data transfer and access. Discuss network tools, traceroute, and communication mediums for effective collaboration. With a well-equipped setup at NIKHEF, including NT systems and Linux farm, this workshop provides a great learning environment. Explore questions on disk space, CPU usage, and file access between NT and Unix systems.
