Network Devices: HUB

Welcome to Cybrary’s CompTIA A+ course. Today’s Module examines network devices, which are the devices that allow our computing systems to communicate, and the various ways in which they work. We begin today’s lesson by discussing the HUB and we’ll explore the importance of this device to the networking environment. We’ll diagram a hubs relationship to other devices on the network examine the three different types of hubs: active, passive and intelligent. Active hubs takes signals from one computer to and re-transmits, boosts and repopulates those signals to other computers, passive hubs means its re-transmits and passes along the signal as is, and intelligent hubs pull double duty.  They receive and read data packets, and associate them with the computer that sent it and only transmits data back packets assigned to that specific computer. And for each tour hub types, you’ll observe the data transmission flows, and their functions and be able to diagram and articulate them at the conclusion of this lesson.
