What are advantages and disadvantages of optical fiber?
Optical Fiber
Optical fiber is a type of dielectric (insulating) material, such as glass or plastic, capable of transporting light. High-speed data can be transmitted through optical fibers by total internal reflection of light. The biggest feature of optical fiber is that it transmits light signals instead of electrical signals. Currently available optical fibers have a data transmission rate of 100 Mbps to 2 Mbps.

Describe CSMA/CA or Carrier Sense Multiple Access with Collision Avoidance.
Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA): This is a wireless network multiple access method defined by IEEE 802.11 standard. CSMA/CA is a modification to CSMA/CD. Collision detection as in CSMA/CD is not applicable for several reason, one reason is Hidden Terminal Problem. To understand this problem, considering that we have three stations 1, … Read more
Describe CSMA/CD or describe the access method of Ether LANs.
CSMA/CD (Carrier Sense Multiple Access with Collision Detection): The IEEE 802.3 defines the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) as the standard access method for traditional Ethernet. Stations in a traditional Ethernet can be connected using a physical bus or star topology, but the logical topology is always a bus. It means that … Read more
