- Objectives: Software
- Differentiate between an operating system and an application
- Describe the parts of a computer and their function
- Identify how a virtual machine can be used
- Describe the properties of memory and storage in terms of cost, storage duration, and volatility
- Describe how local area networks facilitate data sharing and communication within health care institutions
- Define, describe, compare, contrast, identify, recognize, or match definitions or examples for the following terms:
- Analog & Digital
- Bit & Byte
- A Byte is 8 bits.
- Scales of measure
- Compare and contrast analog and digital signals
- Define and describe analog-digital conversion, frequency, sampling rate, amplitude, ranging, precision, Nyquist frequency
- ADC: analog signals being converted to digital for storage in a computer.
- Sampling: The frequency at which a signal is converted/read/recorded.
- ADC Precision of Sampling: Degree to which the digital estimate matches the actual value; affected by bits (sampling and ranging).
- Ranging: The amplitude of the signal that can be captured; peak to peak.
- ADC Frequency of Sampling: 44kHz is high rate and ideal; needs to be frequent so as to catch narrow peaks.
- Nyquist Frequency: The need to sample at least 2x as frequently as the highest freq. component in a signal; rate calculated by doubling the highest freq.
- Describe the relationship between signal frequency and sampling rate
- Both need to be high for an accurate representation of the original analog signal. Ideally, sampling would be twice the signal freq.
- Describe information theory and its components
- Info Theory: Major problem is to reproduce messages exactly.
- Argues that info is a measurable physical quantity.
- Information source, such as a radio, is a component which produces a message.
- Transmitter is a component producing the suitable signal for transmission over a channel.
- Receiver component performs the reverse operation of the transmitter; reconstructing the message from the signal.
- Destination is the component for which a message is intended.
- Info Theory: Major problem is to reproduce messages exactly.
- Define noise
- Data without meaning.
- Identify key functions that software applications perform in health care
- Correctly identify stages of the software development life cycle
- Compare and contrast verification and validation
- Define and describe analog-digital conversion, frequency, sampling rate, amplitude, ranging, precision, Nyquist frequency
