LAN wire configuration

Cat 5 is required for basic 10/100 functionality, you will want Cat 5e for gigabit (1000BaseT) operation. The ethernet cable, are 8 color coded wires. These wires are twisted into 4 pairs of wires, each pair has a common color theme. One wire in the pair being a solid or primarily solid colored wire and the other being a primarily white wire with a colored stripe (Sometimes ethernet cables won't have any color on the striped wire, the only way to tell which is which is to check which wire it is twisted around). Examples of the naming schemes used are: Orange (alternatively Orange/White) for the solid colored wire and White/Orange for the striped cable. The twists are extremely important. RJ45 :- RJ-45 conductor data cable contains 4 pairs of wires each consists of a solid colored wire and a strip of the same color. There are two wiring standards for RJ-45 wiring: T-568A and T-568B. Although there are 4 pairs of wires, 10BaseT/100BaseT Ethernet uses only 2 pairs: Orange and Gr...

Data Mining

Data mining is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence,machine learning, statistics, and database systems. It is sometimes called Knowledge Discovery in Databases (KDD) . The Knowledge Discovery in Databases (KDD) process is commonly defined with the stages:     (1) Selection     (2) Pre-processing     (3) Transformation     (4) Data Mining     (5) Interpretation/Evaluation Data mining involves six common classes of tasks: 1)Anomaly detection (Outlier/change/deviation detection) – The identification of unusual data records, that might be interesting or data errors that require further investigation. 2)Association rule learning (Dependency modeling) – Searches for relationships between variables. For example a supermarket might gather data on customer purchasing habits. Using association rule learning, the supermarke...
