Answer:
A mouse.
Explanation:
An input device can be defined as any device that is typically used for sending data to a computer system.
Generally, all of the output and input device of a computer are known as peripheral (external) devices and they provide data (informations) to the end users in various formats such as video, audio, texts, images etc.
Since input devices are peripheral (external) devices, they can be connected to the computer system wirelessly or through a wired-connection (cable).
Some examples of peripheral (external) devices are monitor, speakers, keyboard, printer, scanner, projector, mouse, etc.
A mouse is an input device that is designed and used to select specific menu options, drag and drop options and to draw something on screen.

Format the text in Small caps. Manually replace the lowercase letters with uppercase letters.
Answer: Local Area Network (LAN)
Explanation:
A Local Area Network (LAN) is a computer network that interconnects computers within a limited physical area such as a residence, school, laboratory, university campus or office building.
An example of LAN network is "Phone, Computer and TV connected to a single network (such as a Home Network) via Cables, Wifi, Bluetooth or Hotspot". When the devices are interconnected or connected to a LAN, it becomes accessible between each other.
A simplest example of a LAN Device is a <em>Home Router.</em>
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.
Answer:
False
Explanation:
Kleene star is a unary operation, we can perform this on a character or set of strings.It means zero or more than zero up to infinite.
It is represented by Vˣ or V+.
For 1, the kleene star will be empty string '∈' or any number of strings.
1ˣ =(∈,1,11,111,1111,11111......)
In question, the empty string '∈' is not present.
