Key Points

• When rice is produced and not polished it is called brown rice.

Additional Information

The correct answer is Accumulator.

Key Points

• An accumulator is a type of register present in a CPU (Central Processing Unit).
• It works as a temporary storage location that keeps an intermediate value in logical and mathematical calculations.
• Intermediate results of execution are progressively stored in the accumulator, replacing the previous value.

Additional Information

• An IR (Instruction Register) saves machine instruction that is currently under execution. It is a register that sits at the top of the memory hierarchy. A variety of registers fulfills different operations in a central processing unit (CPU) – the function of the IR is to keep that currently stacked instruction for use.
• A PC (program counter) is a CPU register that has the address stored for the next instruction to be processed from memory. It is a digital counter required for quicker execution of tasks as well as to keep track of the current execution point. 
• The MAR (Memory Address Register) is the register in the control unit that holds the address of a register to receive or store from or to the storage. The Memory Address Register is half of an interaction between a microprogram and storage.

      • CTRL + F11 = Lock a field.
      • CTRL + SHIFT + F11 = Unlock a field.
      • ALT + F11 = Display Microsoft Visual Basic Code.
      • ALT + SHIFT + F11 = Display Microsoft Visual Studio Code.

​Additional Information

• F8
  • ​​We can access the menu by turning on your computer and pressing the F8 key before Windows starts.
• F9
  • F9 will refresh fields in Word and prompt Outlook to send and receive messages.
• F10
  • ​F10 activates the menu bar or Ribbon of an open application.
  • Shift + F10 is the same as right-clicking on a highlighted icon, file, or Internet link. 

Concept:

The GROUP BY statement groups rows that have the same values into summary rows, like "find the number of customers in each country".

The GROUP BY statement is often used with aggregate functions (COUNT, MAX, MIN, SUM, AVG) to group the result-set by one or more columns.

GROUP BY Syntax

SELECT column_name(s)
FROM table_name
WHERE condition
GROUP BY column_name(s)
ORDER BY column_name(s);

The ORDER BY keyword is used to sort the result-set in ascending or descending order.

The ORDER BY keyword sorts the records in ascending order by default. To sort the records in descending order, use the DESC keyword.

ORDER BY Syntax

SELECT column1, column2, ...
FROM table_name
ORDER BY column1, column2, ... ASC|DESC;

The correct answer is Spinning.

• The process of making thread from the fibre is called Spinning.

Key Points

• Spinning is the process done as a major part of the textile industries.
  • It is the manufacturing process for creating polymer fibres.
  • In the Spinning process, fibres are drawn and twisted from the cotton mass which brings them together to form a yarn
• Ring, Rotor, Air Jet are the different types of spinners used in the textile industries.

Additional Information

• Weaving is a method of textile production in which two different sets of yarns or threads are interlaced at right angles to form a fabric or cloth.
• Ginning is the process of removing the seeds and debris from cotton.
