Question Discussion & Solution

The correct answer is Arithmetic and Logic Unity.

Key Points

• In computing, an arithmetic logic unit (ALU) is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers.
• This is in contrast to a floating-point unit (FPU), which operates on floating-point numbers.
• It is a fundamental building block of many types of computing circuits, including the central processing unit (CPU) of computers, FPUs, and graphics processing units (GPUs).

Additional Information

• Bitwise logical operations used in Arithmetic and Logic Unit:
  • AND - It is true when both the components are true.
  • OR - It gives true when any of the one components is true.
  • Exclusive OR - It is true if and only if its arguments differ (one is true, the other is false). 

The correct answer is Understanding.

Key Points

• UNDERSTANDING:
  • It is a thing that is not performed by machines but requires the human touch.
  • Machines like computers, etc. work according to the commands given to them and can not analyze the action on their own.
  • Thus, understanding is the work not done by a computer.

Additional Information

• COMPUTING:
  • Computing in its absolute terms means using computers for processing data or performing calculations.
  • It can be defined as the process of using computer technology to complete a given goal-oriented task using algorithms.
• PROCESSING:
  • It is the process by which the CPU (Central Processing Unit) of the computer converts the data received into information.
  • In other terms, it may be defined as the action or series of actions undertaken by the CPU to convert data into information.
  • It is for this reason the CPU is regarded as the 'brain' of the computer.
  • The general steps involved in the processing are - fetch, decode, execute, and write back.
• ​OUTPUTTING:
  • ​Output is the result given by a computer after processing the data and the process of delivering the output is termed as 'outputting'.
  • Output is most commonly displayed on the computer screen.
  • The devices capable of showing the output are - Monitor, Printer, Plotters, Speakers, Speech synthesizers, etc.

The correct answer is Insert > Illustration > Chart.

Key Points

• How to create Charts
  • To create a simple chart in PowerPoint, click insert> Chart and pick the chart you want.
  • Click the placeholder that you want to contain the chart.
  • On the Insert Tab, in the illustrations click the chart.
  • In the Insert Chart dialog box, click a chart and then click ok.

Additional Information

• MS PowerPoint
  • It is a presentation program used to present data and information by using text, diagrams with animation, images, and transitional effects in the form of slides.
  • It is developed by Robert Gaskins and Dennis Austin.

The correct answer is 14.

Key Points

• If the font size of a text in MS-Word 2016 document is 12.
• If we select the text and press CTRL+SHIFT+> once, then the font size of the text will be 14.
• Font sizes are measured in points; 1 point (abbreviated pt) is equal to 1/72 of an inch.
• The default size increase in MS word is two points. 
• The point size refers to the height of a character.
• Thus, a 12-pt font is 1/6 inch in height.

Additional Information

• Microsoft Word uses the Calibri font and 11 point font size by default. 
• To increase the font size, press Ctrl + ] . (Press and hold the Ctrl, then press the right bracket key.)
• To decrease the font size, press Ctrl + [.

The correct answer is Ctrl+N.

Key Points

• Ctrl+N is the shortcut key used to open a New Document in the MS office.
• In the new document new worksheet is opened in the same window. 

Additional Information

• Some important shortcuts used in MS Excel:
  • Ctrl + O Open an existing workbook.
  • Ctrl + S Save the active workbook.
  • F12 Save the active workbook under a new name, displays the Save as dialog box.
  • Ctrl + W Close the active workbook.
  • Ctrl + C Copy the contents of the selected cells to Clipboard.
  • Ctrl + X Cut the contents of the selected cells to Clipboard.
