Ethernet cables are the physical backbone of modern networks, and this episode focuses on the different categories of twisted-pair cabling you’ll need to recognize. We explain the differences between Cat 5, Cat 5e, Cat 6, and Cat 6a in terms of bandwidth, maximum distance, shielding, and application. You’ll learn why Cat 5 is becoming obsolete and why Cat 6a is preferred for environments requiring high speed over longer distances.

We also explore which standards support GIGABIT Ethernet and how crosstalk and interference are reduced through cable design. Understanding these differences will help you make correct choices on the exam when asked about performance, installation, or compatibility issues. This episode makes cabling standards less abstract and more memorable through practical descriptions. Brought to you by BareMetalCyber.com.
