all organisms are made of cells and come from cells Cell theory When the cell size (INCREASES or DECREASES), the membrane gets smaller compared to cell volume. increases the study of cells Cytology "how can cork float" Took sections, looked under microscope and found that they had tiny chambers (aka cells) Robert Hooke Part of electromagnetic spectrum via sun, delivering energy that can be recorded as wavelengths (convert into color - ROY G BIV: red, orange, yellow, green, blue, indig...

2.4 GHz wavelength - longer wavelengths, better range larger channel widths - provide faster speed and throughput but can create greater interference 5 GHz wavelength - supports faster data rates at shorter distances, suited for high density deployments because of greater number of channels that do not overlap What channel widths do 2.4 GHz support? - 20 and 40 MHz What channel widths do 5 GHz support? - 20, 40, 80, 160 MHz omnidirectional antenna - Can transmit and receive with 360-degree...
