Carrier Sense Multiple Access with Collision Avoidance. However‚ simple CSMA is susceptible to the hidden node problem‚ especially in so called ad hoc networks where a node may communicate directly with every other node in range or using intermediate nodes as relays otherwise. Hidden nodes cause costly packet collisions and thus significantly affect network performance. In order to combat the hidden node problem‚ a mechanism known as Request to Send/Clear to Send (RTS/CTS) handshake is often used. RTS/CTS

Christopher Scott Biol 241 homework Professor: Greg Crowther 1. Compare and contrast the reasons cell division is important for unicellular and multicellular organisms. Cell division is the method in which single celled organisms reproduce. Cell division allows multi-cellular to grow and repair dead or damaged cells 2. Provide an example of why cell division remains important to an adult organism even after it isfully developed. Some cells divide to heal wounds such as cuts or broken bones.
