External devices that connect to a computer, such as USB and Thunderbolt devices.

• A. Crimpers
• B. Peripheral devices
• C. Cable testers
• D. SFP

Answer: (B)

External devices that connect to a computer are called peripheral devices. These are elements that extend the computer’s capabilities by providing extra input, output, or storage through interfaces like USB or Thunderbolt. Examples include keyboards, mice, printers, external drives, and webcams—devices that you attach to the computer to perform additional functions. The other options don’t fit this idea. Crimpers are tools used to terminate cables, not devices that interface with a computer. Cable testers check the integrity of cables rather than adding functionality to a computer. SFP modules are network transceivers used in networking gear, not general external devices you commonly hook up to a computer for everyday use.
