Summary - Essay Example Grouping together of the nodes forms an ad hoc network that exposes the system to errors. The allowance of each node to interfere with each others transmission causes hidden and revealed problems within a wireless network station. The solution for this problem is available using the IEE standard and Point Coordination. The wireless networks have more chances of undetected frame collisions at the MAC sub layer. Detecting the collision and retransmitting the lost frame is imperative practice in preventing the loss of data integrity. However, the wired (Ethernet) local data networks rarely experience data integrity issues. Therefore, collision control is unnecessary for the Ethernet and wired LANs. The wireless network faces transmission issues when signal problems occur due to signal-bounce. Consequently, this necessitates the need for the MAC layer to solve these challenges. The MAC sub-layer for wired segments does not need collision avoidance protocol despite not having much transmission capabilities as those in wireless LANs. The wireless LANs is prevalent than the wired ones as they have various benefits found at the MAC sub layer of the network

Answer question - Essay Example The teachings by Moishe the Beadle are similar to Buber’s Hasidic teachings. Moishe teaches that there are a thousand and one ways that lead to the orchard of truth and each man has to find his own way to get there (Wiesel, 2006). Buber shares the same views as he argues that all men can access God, but each through his own way (Buber, 1958). During his various experiences, Wiesel was once in a situation where they had to celebrate the Day of Atonement by fasting. Wiesel went against traditional believes of fasting both as a symbol of rebellion against God’s silence as well as a necessary means of keeping up strength in the face of adversity and torture. Buber explains that in Hasidism, one can serve through learning, prayer, fasting or through eating (Buber, 1958). Accordingly, one should choose depending on what they view as right and avoid imitating others. On entering Auschwitz, Wiesel and his group of prisoners were greeted by a young pole with Hasidic inclination. He argues that by driving despair and through camaraderie, they will be able to overcome their hardship. Hasidism according to Buber shares a similar view as he argues that while the world is an irradiation of the Divine, it is described by independence of existence and striving and that man is to affirm the world and transform both him and the world at large to the image that God would approve. The notable difference between Buber and Wiesel accounts is the latter’s conclusion that man and man alone is the master of the universe. Buber argues that a divine spark exists in all men and that it can either be perverted or liberated and re-joined with the Origin (God) (Buber, 1958). Personally, I do not agree with Wiesel conclusion that we live in a world without God and that man alone is the master of nature and of the world. I however sympathize with
