(OSI). It is the layer that deals with all the measurable, physical entities associated with the network. At this layer it is specified how much bandwidth (Baseband or Broadband) will be used in the transmission of data on the network. This layer also includes the physical topology (physical lay out) of the network such as: Bus, Star, Ring or Mesh. The Physical Layer includes these devices: Network Interface Cards (NICs), Transceivers, Hubs, Multistation Access Units (MAUs), Repeaters and Cables
Bus, Ring and Star topologies The term Topology refers to the physical or logical shape or layout of a network. Communication between different nodes within a network is determined by its topology. Mesh, Bus, Ring and Star are four of the most common network topologies, each with advantages and disadvantages in relation to each other. Mesh Topology The Mesh topology is true to its name in that there are multiple redundant interconnections between network nodes. A mesh network can employ one
Physical Design (Graphics Not Available) Understanding network topology can tell one a great deal about installing or expanding a network. At its basic level, the topology of a network refers to the way in which all its pieces have been connected. That is, it refers to the layout of the computers, printers, and other equipment hooked to the network (TechTarget 2006). Because cables connect computing resources together for a network, network's topology is also a function of the way in which
celebrities are introduced; rules of propriety in regards to privacy are discarded. Movie studios, networks, gossip columnist and the stars themselves recognize the unique power the public holds in maintaining the celebrity’s fame. In attempt to preserve fame and appease society’s ever increasing “need to know”, reality and fantasy are merged, the outcome is the loss of anonymity and privacy to the star.

Difference between Logical & Physical Design of a Network When we look at the differences between logical design and physical design of a network it is easy to think of it as the logical as the functional part and physical as the seeing it part. With that stated there is more to this than just the functional and seeing parts. In order to understand the differences from one to the other, we need more information. In the following paragraphs I will try to outline what makes up the differences between
Celestial bodies and literature have a relationship that extends beyond the simple “star light, star bright, I wish I may, I wish I might…” rhyme. Over the years, man has found a muse in the heavens and has used this inspiration to create to works that speak to generations of people. The Orion constellation is located on the celestial equator, and is one of the most well-known and identifiable constellations in the sky and can be seen throughout the world. Orion’s popularity has lead to its inclusion
What is Network Topologies? Definition Network topologies can be defined as structures of a computer network. It is normally refers to how the nodes or computer are connecting and working together within the network to do the data transferring task. Brief history of network topologies The sharing of data and information is way more difficult in the early 1960s compared to the sharing system nowadays because each of the computers was physically shared. The researcher had come out with a solution
Network topologies have some advantages and some disadvantages as well. This essay discusses the main advantages and disadvantages of three of these main topology technologies, to mention, the ring, the bus, and the star, showing the associated wiring types for each one of these topologies. In the ring topology, each node is connected to two other nodes, hence, “data sent between nodes will typically require paths of at least two links” (Mansfield, K. C., & Antaonakos, J. L., 2010, p. 27). Among
Network Topologies Analysis and Comparison The bus topology connects several computers, or nodes, with a communication channel, often a single cable. Computers on a bus either transmit data to other computers on the network or listen for data from other computers on the network. They are not responsible for moving data from one computer to the next. Consequently, if one computer fails, it does not affect the rest of the network. Because the data, or electronic signal, is sent to the entire network
Star Wars and Religion Methodology In conducting my research on Star Wars, I wanted to make sure that I kind of found a variety of sources. I decided to do my field report on Star Wars originally because I was aware that I needed to include an interview component in this report. I immediately thought of my R.A., who just happens to be an incredibly huge Star Wars fan. I knew that I would have to investigate some element of the movies and religion has always been a very controversial topic
the principles that a star that has an orbiting planet will experience a gravitational force from the planet and hence move in its own small orbit in response. This will result in changes in the speed of the star as it moves towards and away from the observer i.e Earth and this shall be seen as variations in the radial velocity of the star with respect to the Earth. The radial velocity of the star can be worked out from the shifting of spectral lines in spectra of the star due to the Doppler effect
There are numerous mysteries contained within the Cosmos that have yet to fully be analyzed and appreciated. The unique events that transpire within the Universe everyday are unbelievably remarkable and captivating. Hidden within the immense ocean of stars we see every night lays an even more incredible spectacle in the form of Nebulae. The paragraphs that ensue will delve into the creation of Nebulae, and the many intriguing aspects of the most visually appealing amongst these particular phenomena.
Hertzsprung-Russell Diagram or, the H-R Diagram for short, is a graph which plots stars according to their temperature and absolute magnitude. This graph reveals a pattern, which in fact is quite interesting. The H-R Diagram is named for the two astronomers, Ejnar Hertzsprung and Henry Russell, who discovered this pattern of stars. These two astronomers independently discovered that comparing magnitudes and spectral class (color) of stars yielded a lot of information about them. One key purpose of the H-R diagram
Jersey, to live with their mom. After moving to New Jersey, Star started to shine in school. She always held the top grades throughout school and after graduating from a parochial school she enrolled in the American University in Washington, DC. While at American, Star sang in the gospel choir and joined Alpha Kappa Alpha, a very prestigious African-American sorority. She was a popular student on campus and was given the nickname of “Star.” It was at American that Jones was diagnosed with inoperable
thinking that has ever graced this earth. Hawking was born on January 8, 1942 in Oxford, England. He spent most of his childhood in and around London, and was always a bit of a self-educator. He was interested in the stars, and his family used to lie out on the grass looking at the stars. His writing was appalling, and he was one of the only people at school to be issued with a copybook. He was never really good with his hands, and gave the impression of nervousness, being lanky and awkward in movement
operator born in France that working in Britain. He opened Le Gavroche with his brother Albert Roux that becomes the first three Michelin starred restaurant in Britain. Moreover, Waterside Inn also the first restaurant outside France that holding three stars for nearly 30 years1. Michel Roux Senior was born in Charolles, France, in 1941. After war, he moved to Paris with his family, and then his father opened a charcuterie after that. Unfortunately, it went bankrupt and closed. His father left the family
Space: The Final Frontier Astronomy is a word derived from Greek; it comes from the merging of two words, the first being ‘star’ and the second being ‘law.’ Like the name suggests, astronomy is the study of stars, in addition to countless other aspects of space and the universe in general. Being such a broad subject, there are of course many different branches of astronomy. These include general astrophysics, theoretical astrophysics, astrobiology, physical cosmology, galactic astronomy… you get
A star is a self-radiant divine body consisting of a mass of gas held together by its own gravity. The birth of a star begins inside a molecular cloud. Stars form inside these somewhat dense concentrations of interstellar gas and dust. The process of star formation has long been a mystery because of viewing limitations. Large amounts of small solid particles blocked our view of the stars which are beyond the molecular cloud. Infrared technology now provides some insight on how a star is formed

Earth’s galaxy, the Milky Way consists of more than 100 billion stars, many of which can be interpreted by human visual perception, while other can only be observed with the aid of a magnifying or light-collecting optical device such as a telescope. The stars are organized into various groupings according to their visible arrangement as observed in earth’s atmosphere. Human beings from cultures of eras bygone such as the Greeks, Romans, and Babylonians, and bestowed most, if not all of the titles
