Data 

Data cabling is a fundamental part of IT infrastructure. It enables communication between computers, servers, printers, phones and other equipment. Wired connections are generally more secure than wireless ones, which can be vulnerable to external access. Data cabling is great for home and small office networks where distances between equipment is typically shorter than commercial and industrial settings.
