What aspects of Ethernet have remained relatively unchanged over the years, and what aspects have changed?
What will be an ideal response?
Ethernet's simplicity and ease of use and installation have remained unchanged. The Ethernet
frame has remained relatively unchanged. Ethernet is still usually connected in a star topolo
gy, but the center of the star is a switch rather than a hub these days. The cabling for Ethernet
has evolved from coaxial to unshielded twisted pair to fiber-optic. Unshielded twisted pair is
still widely used. Fiber-optic is reserved mostly for data centers, links between switches, and
high-end devices.
