Computer Networks NETWORKING CONCEPTS Network A network is basically an interconnection of various points to make a connected system e.g Road‚ Telephone‚ Social Data Network A computer network therefore refers to an interconnection of computers and other peripherals by use of a communication link Peer to Peer Networks In a peer-to-peer network‚ all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed

However‚ with daily technology advancements made in society and the requirement for global data connectivity‚ satellites are increasingly being used to provide data communication links at all data rates ranging from 64 Kbps to 155 Mbps (Buchsbaum). Wireless technology allows data to be sent out into space to a satellite and back to earth to provide connectivity among many different network clients. The network can be designed to

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane‚ in a phospholipid bilayer. Phospholipid molecules form two layers‚ with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid‚ and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable‚ and allows oxygen

As time progresses‚ the human population in Singapore rises rapidly‚ there will be a greater demand for public transport. This would inevitably lead to trains and buses being over crowded if no changes are made with regards to the effectiveness of this complex system. Due to an ineffective and inferior system‚ the frequency of arrivals of trains and buses would be long and unpredictable. Further more there will also be an increased number of technical glitches and breakdowns. In December 2011‚ two

Pex7p Transport Role As previously stated‚ the location of the mutation causing the lethal RCDP1 phenotype has been narrowed down to the 10-exon PEX7 gene. wt PEX7 is translated as a cytosolic import receptor Pex7p‚ responsible for binding enzymes destined for the peroxisomal matrix marked by the N-terminal peroxisome-targeting signal 2 (PTS2). In a normal cell‚ the Pex7p receptor has a PTS2 receptor region that recognizes and binds the PTS2 of the localized protein in the cytosol‚ necessary for

INTRODUCTION Nowadays‚ public transport plays an important role in each country in the world. This is because public transport is the most important issue in our lives. People have different views about public transport. In this report the authors will compare the views on public transport between 0 ELICOS students and Australians. 1.1. Background Regarding the selection of public transport of Australian‚ the survey have shown that the rate of using public transport increases significantly between
