Networking Local Area Networks Hood College Dept. of Computer Science Spring 2013 Layer 2: The Datalink Layer • • 2 Datalink layer provides a reliable communications link between devices. Breaks a data stream into chunks called frames‚ or cells. Three key functions: • error detection • error correction • flow control • • In LANs DL can be broken down into two sub-layers: • media access control (MAC) • logical link control (LLC). • flow and error control Datalink Layer

Causes of medication errors and methods to reduce errors Nurses have an ethical and legal responsibility to assess a patient’s need for a drug‚ administer it safely and correctly and evaluate the response to it. They should always make patient safety a priority because patients rely on the nurse’s skills‚ knowledge and professionalism. Nurses have a critical role in administering medications to the patients by following the six rights of drug administration. These six rights are: Right medication

Chapter 1 1. INTRODUCTION Artificial Neural Networks are being touted as the wave of the future in computing. They are indeed self learning mechanisms which don ’t require the traditional skills of a programmer. But unfortunately‚ misconceptions have arisen. Writers have hyped that these neuron-inspired processors can do almost anything. Fig. 1.1 Neural Network These exaggerations have created disappointments for some potential users who

Network Topology and Wiring Tiearia Fariss NTC/361 Professor: Larry Schreider December Network Topologies are the different arrangements that contain many different element such as links‚ nodes‚ etc. This helps with communication and network information processing. This is a major part of today’s technology and is used by big business as well as for home and personal use. There have been eight different network topologies that have been recognized though out a study.. Throughout this paper

elements of essential network services. The basic difference between a wired and a wireless network is self-explanatory. A wired network uses wires to communicate whereas a wireless network uses radio waves. Another difference and how one technology gets an edge over the other. Wired networks are easy to set up and troubleshoot where wireless networks are comparatively difficult to set up‚ maintain‚ and troubleshoot. Wired networks make you immobile while wireless ones provide you with convenience of
