Thunderbolt — CompTIA A+ Core 1 (220-1101) Practice Questions
Thunderbolt is a high-speed hardware interface developed by Intel, commonly found on modern laptops and desktops, that combines PCIe data lanes with DisplayPort video over a single connector. The 220-1101 exam expects technicians to recognize Thunderbolt versions, their bandwidth ratings (up to 40 Gbps for Thunderbolt 3 and 4), and their use cases including external GPUs, high-resolution displays, and daisy-chaining devices. Thunderbolt 3 and 4 use the USB-C physical connector, which means technicians must be able to distinguish Thunderbolt-capable ports from standard USB-C ports by their lightning bolt icon or specification sheet. Knowing connector compatibility and bandwidth limitations is essential for supporting peripheral installations.
