sends out to all the computers except the senders on the network. This can cause a collision on the network if more than one piece of data packet is sent across the wire. CSMA/CD helps with the collisions by using a system where before data packet is sent‚ it can inspect the wire for data packet‚ and if there is data packet on the wire it sets a random timer and investigates again to find out if it is able to send the data packet. Now for this being the way the hub works all the computers share the

Locked In: An Analysis of the Environment in “The Cage” The wire of the fence bounds the man within its clutches. Escape seems to be in sight‚ but is lost when he seems to have reached it. “The Cage” by Heinrich Boll is a short story about a man who is closed in by the boundaries of metal wire as a prisoner‚ looking for relief. The man ends up getting a miserable fate. In Heinrich Boll’s “The Cage‚” the author signifies how a person can change due to miserable environmental conditions and loss

established experimentally that the current in a metal wire is directly proportional to the potential difference V applied to its two ends‚ provided that the physical conditions such as temperature remain constant: I∞V Exactly how much current flows in a wire depends not only on the voltage‚ but also on the resistance the wire offers to the flow of electrons. Electrons are showed down because of interactions with the atoms of the wire. The higher the resistance‚ the less the current for a

(Note: some recent copper coins‚ including the newer U.S. pennies‚ contain low amounts of copper mixed with zinc. If in doubt‚ use a pure copper strip.) They are stuck into the lemon‚ and wires are attached to each one. The wires should be attached securely to form a good electrical contact. If the other ends of the wires are attached to a small light bulb (flashlight bulb) there should be sufficient current to light it. Note that the metal pieces should be clean‚ and that they should not touch inside

ABSTRACT Flood is one of the disastrous phenomena that caused a lot of deaths to some other uninformed area in the province. The researchers from Negros Occidental High School proposed a study with the objective to construct and develop a flood detection device‚ present a practical device‚ and introduce the device to a certain residents in the province that needs to be aware of flood. After the device was constructed‚ the researchers tested the device in a cup of water. During the testing of device
