Their design is based on the experience learned from today’s most widely deployed access switches, the Cisco Catalyst ® 2950. I would recommend you start your CCNA path by learning about the Ethernet standard. Cisco ME 3400 Series Ethernet Access Switches The Cisco ® ME 3400 Series Ethernet Access Switches are a series of next-generation Layer 2 and Layer 3 customer-located devices purposely built for service providers. The technical specifications of the Cisco 2950 Switch are as follows: Feature. But, as is true with many things in the computer world what a layman calls something doesn't necessarily translate when you actually start learning about the technology. It has become common to refer to an RJ-45 jack as an Ethernet jack in the same way people refer to an adhesive bandage as a Band-Aid. The Cisco Catalyst 2950SX-48-SI, 2950T-48-SI, 2950SX-24, 2950-12 are standalone, fixed-configuration, managed 10/100 switches providing basic workgroup connectivity for small to medium-sized companies.

Moreover, you can use RJ-45 ports for other types of connections, like the serial console port of a Cisco switch, T1 serial connections, and other things. 2 OVERVIEW Cisco® Catalyst® 2960-L Series Switches are fixed-configuration, Gigabit Ethernet switches that provide enterprise-class access switching for branch offices, out-of-the-wiring-closet applications, and critical Internet of Things (IoT) deployments, as well as small and medium-sized businesses. But, you can also do Ethernet over fiber which is obviously a completely different cable and port type. For a copper based Ethernet connection it is standard to use an RJ-45 port (but we used to use coax, like your Cable TV or Cablemodem way back in the day). Ethernet is not a physical connector, Ethernet is a protocol or standard for transmitting and receiving data.
