The correct answer is 'an action which makes a bad situation worse'.

Key Points

• The idiom "a turn of the screw" means to make a bad situation worse by adding further complications or difficulties to it. It is often used to describe a situation where things are already bad, but someone or something makes it even worse by taking an action that aggravates the situation.

The correct answer is ROM.

Key Points

• ROM
  • Read-Only Memory is a ROM in a computer.
  • Read-only memory is a storage medium that permanently stores data on computers and electronic devices.
  • The data stored in these chips is nonvolatile i.e. it is not lost when power is removed.
  • There are five basic ROM types:
    • ROM: Read-Only Memory.
    • PROM: Programmable read-only memory.
    • EPROM: Erasable programmable read-only memory.
    • EEPROM: Electrically erasable programmable read-only memory.
    • Flash memory: Flash memory, a type of EEPROM that uses in-circuit wiring. 
  • BIOS uses Flash memory.

Additional Information

• Register
  • The smallest and fastest memory of a computer is registered memory located in the computer's central processing unit(CPU).
  • It generally stores the most used instructions, data, etc. which are to be used by CPU.
  • Control Unit is part of the CPU.
  • It advises the input and output devices, and computer memory on how to respond to the instructions sent to the processor.
• RAM
  • It stores data that the computer needs to use temporarily. So it is faster than the secondary storage devices. It is a volatile memory i.e. the data disappear from it when the power is off.
  • It is known as the Read-Write Memory. i.e. the user can write information into RAM and read information from it.
  • It is called random access since any memory location can be accessed randomly for reading and writing. The access time is the same for each memory location.
  • It is usually called “temporary” memory, which means that when the system is shut down, the memory is lost.
• Cache
  • A cache memory is used by the central processing unit of a computer to reduce the average cost time or energy to access data from the main memory.
  • Generally Cache memory is logically positioned between CPU and main memory.

The correct answer is VSTACK.

Key Points

• MS Excel allows you to combine two or more ranges of cells or arrays in two ways i.e., vertically or horizontally.
• VSTACK is a function that combines two or more arrays vertically. Hence option 2 is correct.
  • Its syntax is VSTACK(array1, [array2],...).

Additional Information

• HSTACK is another function that works similarly to the VSTACK function, but the former function combines the range of the cells horizontally.
  • Its syntax is HSTACK(array1, [array2],..).
• Excel provides SORT() function to arrange the values according to the given requirements.

The Name box in Excel is a useful tool that allows users to easily navigate and reference specific cells or ranges within a worksheet. Here is a detailed explanation of the Name box and its features:
Definition of the Name box:
The Name box is a designated area in Excel where users can see and enter the names of cells or ranges. It is located to the left of the formula bar, making it easily accessible for users to interact with.
Features of the Name box:
1. Shows location of the previously active cell: When a user selects a cell or range, the Name box displays the address of the previously active cell. This is helpful for users to keep track of their current position within the worksheet.
2. Appears at the left of the formula bar: The Name box is positioned to the left of the formula bar in Excel. This placement ensures that users can quickly locate and utilize the Name box while working with formulas and functions.
3. Allows users to enter names for cells or ranges: Users can also manually enter names for cells or ranges directly into the Name box. This feature enables users to create custom names for specific cells or ranges, making it easier to reference them in formulas or data analysis.
4. Provides a dropdown list of named cells or ranges: The Name box includes a dropdown list that displays all the named cells or ranges within the current workbook. Users can select a name from this list to navigate directly to the corresponding cell or range.
5. Facilitates quick navigation within a worksheet: By entering a cell or range name into the Name box, users can instantly move their active cell to the specified location. This feature eliminates the need for manual scrolling and clicking, making navigation more efficient.
In conclusion, the Name box in Excel serves as a valuable tool for navigating, referencing, and managing cells or ranges within a worksheet. Its placement, functionality, and user-friendly features make it an essential component of Excel's interface.

The correct answer is Datasheet.

Key Points

• Datasheet
  • Each table that appears as a spreadsheet grid is called a datasheet. Hence, Option 2 is correct.
  • A datasheet is a useful way of viewing data in Access.
  • A database is a collection of tables.
  • Most importantly, datasheet view allows a user to view many table records at the same time.
  • In datasheet view, information is displayed in rows and columns—similar to a spreadsheet.
  • Records are displayed as rows, so each row is an individual record.
  • Within each row, columns represent fields within the record.
  • At the top of the datasheet, a window is the title bar, the Quick Access toolbar, and the Ribbon.
  • The bottom of the window has a status bar and on the right side of the window is a scroll bar as you would expect.
  • Many of the features that are common to spreadsheets are present in Access datasheet windows.
  • A user can modify row height, column width, font size to change the amount of data that fits without scrolling.
  • A user can also change the order of the rows or columns displayed in the window.
  • Datasheet views are a common display tool for tables, queries, and forms in Access.
  • There are some irregularities in the functionality of the datasheet windows for these depending on the underlying data sources.

Additional Information

• Query
  • A query is like a saved filter. It enables us to combine data into a single datasheet from multiple tables.
• Record
  • A record is a row in a table that consists of information about something.
• Table
  • A spreadsheet table, in OpenGL Tablets, is an analog of the Excel table with rows, columns, formulas, and calculations as contents.
  • Spreadsheets can also call decision tables or other executable tables to make decisions on values, and based on those, make calculations.
