Final answer:
A stacking cable is used to connect switches together to act as one unit.
Step-by-step explanation:
The type of cable that allows you to stack switches together to act as one is called a stacking cable. This type of cable is used in computer networking to connect multiple switches together in a stack, allowing them to function as a single unit. Stacking cables typically use high-speed interfaces such as 10 Gigabit Ethernet or 40 Gigabit Ethernet to provide fast and reliable communication between the switches. They allow for increased scalability, easier management, and simplified network architecture.
For example, if you have two switches that support stacking, you can connect them using a stacking cable to create a stack. The switches in the stack can then be managed as a single entity, with features such as shared configuration, unified management, and improved redundancy.
