Why is it worth remembering “all people seem to need data processing”? a) because data processing is the real reason for a network engineer. b) because that will you remember the osi reference model. c) because that is an iso standard for network engineers to know. d) because that is a mnemonic for the iso model.

Most networking media send data using in which data is represented by only two discrete states: 0s and 1s. a. digital signals b. contiguous signals c. ramp signals d. exponential signals

In the context of it jobs in the information systems field. a is responsible for database design and implementation

5.a fishing rod is formed from a composite material of 0.5 kg of glass fibers embedded in a matrix of 0.5 kg of epoxy resin. the glass fibers are assumed to be long, continuous and unidirectional. to achieve a greater stiffness it is proposed to use a different composite that is comprised of long continuous carbon fibers that will be embedded in a matrix of 0.5 kg of epoxy resin. if the modulus of elasticity of the carbon fiber composite is 10% greater than the elastic modulus of the glass fiber composite, estimate the mass of carbon fibers that will be used to make the carbon fiber composite. assume the applied tensile stress is parallel to the direction of the long axis of the fibers. the epoxy resin, glass fiber, and carbon fiber have an elastic modulus of 5, 86, and 350 gpa respectively and a density of 1100, 2500, and 1800 respectively.
