Document Summary
All of the following are functions of the receiver except: Atten coef= . 5 x f x depth. Binary numbers: a group of bits, a series of zeroes and ones, digital means binary, not decimal, byte: 8 bits, 8 bits can store 2^8= 256 shades of gray, word: 16 bits (2 bytes) 2^16= 65,536. D: analog, real world: a variable attains a continuum of values, digital: Computer systems: hardware, computer world: a variable attains only discrete values. 16 gb of ram that cpu can access very quickly. Pixel density: pixel is the smallest element of a digital picture. The detail is called spatial or detail resolution: when pixel density limits spatial resolution Networks: server is a dedicated computer for image storage, firewall blocks access to the network for protection, encryption and authentication, switch= router. Questions: how many shades of gray can be represented by a group of.
