The layers of Earth How do scientists know what is in the center of the earth? How can we know what the core of the earth is made of‚ if scientists have never studied any materials from a depth below 7.5 miles? Earth is approximately 4.6 billion years old‚ and over this time period‚ many things have changed inside and out. The formation of our planet is quite amazing. Earth consists of multiple layers. The three most distinct or main layers are the core‚ mantle and crust. The inner portion is

The Seven Layers of the OSI Model Kevin Ludwig Bryant and Stratton College TECH 140 Khaled Sabha 12.08.2009 There are seven layers in the OSI model. Each layer has a function or purpose that is used to set up a network. The International Organization for Standardization began to develop the OSI framework in 1984. The purpose was to have each layer interact with the layer directly beneath it. The layers are starting from the top: Application‚ Presentation‚ Session‚ Transport‚ Network

target protocols to exploit are the Address Resolution Protocol (ARP)‚ and the Domain Name System (DNS). Steps have been taken to make these protocols more secure in order to prevent MitM attacks. Furthermore‚ the Transport Layer Security (TLS) (and its predecessor‚ Secure Sockets Layer (SSL)) mitigate the risk from MitM attacks over the internet. One of the more targeted protocols to exploit is the Address Resolution Protocol (ARP). This protocol converts

Sublayers of the data link layer The data link layer has two sublayers: logical link control (LLC) and media access control (MAC). Logical link control sublayer The uppermost sublayer‚ LLC‚ multiplexes protocols running atop the data link layer‚ and optionally provides flow control‚ acknowledgment‚ and error notification. The LLC provides addressing and control of the data link. It specifies which mechanisms are to be used for addressing stations over the transmission medium and for

The environment is affected by the deposition in the ozone layer.It is directly affecting the environment‚ because the environment is being negatively impacted‚ because of the depletion in the ozone. This depletion was created‚ because of all the CFC that is being released by all the factories and other machines that pollute the air. The UVB radiation affects the physiological and developmental processes of plants. Even though there is the existence of various machines and methods to reduce or repair

4. The Medium Access Sub Layer Broadcast channels [or multi-access channels] are a category of networks and the key issue is how to determine who gets to use the channel when there is competition for it. The protocols which define these factors belong to a sub layer of data link layer called the MAC(medium access control)sub layer. ALOHA: Norman Abramson devised a new and elegant method to solve the channel allocation problem called the “ALOHA” system which used ground-based Radio broad
