6. What are the Benefits of Cat 5 Cable?

The benefits of cat 5 cables are listed below:

  • One of the significant advantages of cat 5 cable is that it is affordable.
  • It offers high transfer speed.
  • It is easy to install.
  • Even though there are other better wires on the market, Cat 5 adaptability makes it perfect for many applications, including computer networks and telephone lines.

7. What are the Disadvantages of Cat 5 Cable?

Since you are aware of what is a cat 5 cable and what is Cat 5 cable used for, note that the disadvantage of the Cat 5 cable is the amount of data that can be transmitted over the Cat 5 cable. The upper end of the Cat 5 cable has minimal data transfer capacity. Although cable is still appropriate for residential networking because it can only handle 100 megabits per second, it is less useful for more extensive corporate networks or any operation that calls for massive data streams, such as transfers of contemporary television. Also, Cat 5 cable is sensitive to interference, and cross-talk interference can reduce transfer speeds.
