Computational thinking- the thought processes involved in formulating a problem and expressing its solution(s) in such a way that a computer—human or machine—can effectively carry out. Computational Thinking is an iterative process based on three stages.

Problem solving process- The process of working through details of a problem to reach a solution. Problem solving may include mathematical or systematic operations and can be a gauge of an individual's critical thinking skills.

Data- facts and statistics collected together for reference or analysis.

Information- facts provided or learned about something or someone.

Algorithm- a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.

Aggregate data- aggregate data are data combined from several measurements. When data are aggregated, groups of observations are replaced with summary statistics based on those observations. In a data warehouse, the use of aggregate data dramatically reduces the time to query large sets of data.

Discovery Data- in the context of IT, is the process of extracting actionable patterns from data. The extraction is generally performed by humans or, in certain cases, by artificial intelligence systems.

Place the optical discs in the increasing order of storage capacity.<br><br> UDO<br> CD<br> DVD
romanna [79]
<h2>Hello!</h2>

The answer is:

  1. CD
  2. DVD
  3. UDO
<h2>Why?</h2>

Optical disks are circular disks used as storage for binary data usually made of polycarbonate. The data is stored in the disc using a laser machine and accessed using a laser diode illuminating the data path in an optical disc drive.

CD: Compact Discs are the most basic optical disk used today, with only a capacity that goes from 0.7 GB (700 MB) to 0.84 GB (840 MB).

DVD: Digital Versatile Discs increase the storage up to 6 times compared with a CD, the capacity of DVDs optical disks goes from 4.7 GB (4700 MB) to about 17 GB(17000 MB).

UDO: Ultra Density Optical have high capacity storage that goes from 30 GB (30000 MB) to about 60 GB (6000 MB).

Have a nice day!

never [62]

Answer:

True

Explanation:

Solution

ZigBee uses unlicensed frequency bands but operate at slower speed or data rates.

ZigBee: This communication is particular designed for control and sensor networks on IEEE 802.15.4 requirement for wireless personal area networks (WPANs), and it is a outcome from Zigbee alliance.

This communication level defines physical and  (MAC) which is refereed to as the Media Access Control layers to manage many devices at low-data rates.
