24. Name the kind of network topology where each node directly links to every other node.
25. One of the major demerits of this device is that it negatively affects the network performance by recreating any incoming signal on its port and then sent it out to all the connected ports. Name the device?
26. Name the device that comprises of several connector ports and blocks and used in cable management?
27. Give 3 characteristic features associated with an OLED display?
