Yes, You can edit the contents of a cell in the formula-bar or directly in the cell.

So, the given sentence is TRUE.

What is a Formula-bar?

The Formula-bar is a feature in spread-sheet software, that displays the contents of the selected cell. It is located above the spread-sheet and is usually labeled with the letter "fx" to indicate that it is used to enter formulas.

The Formula-bar allows you to view and edit the contents of a cell, including formulas, functions, and data. When you click on a cell, its contents will be displayed in the Formula-bar, and you can edit the contents directly in the bar. This is useful for making quick changes to cell contents without having to navigate to the cell itself.

In most spread-sheet software programs, such as

Editing in the Formula-bar: To edit cell contents in the Formula-bar, you can click on the cell that you want to edit. The cell contents will appear in the Formula-bar, and you can make changes directly in the bar. Once you have made the necessary changes, you can press the Enter key on your keyboard to apply them. This method is particularly useful for editing long or complex cell contents, as it allows you to view and edit the entire content without needing to scroll or expand the cell.

Editing in the Cell itself: To edit cell contents directly in the cell, you can double-click on the cell that you want to edit, and then make the necessary changes. Alternatively, you can select the cell and then start typing, which will overwrite the existing content. This method is particularly useful for editing short or simple cell contents, as it allows you to quickly edit them without needing to navigate away from the cell.

Hence, In both cases, you can edit cell contents in both the formula-bar and the cell itself. To edit the formula-bar, click on the cell and make changes in the bar. To edit in the cell, double-click on the cell or start typing when the cell is selected.

Data from external devices travels from the input device to the I/O controller, then to the system bus, and finally to the CPU for processing in a computer.

The arrows representing data from external devices should take the path from the input device to the Input/Output (I/O) controller, then to the system bus, and finally to the central processing unit (CPU) for processing.

The data path in a computer can be summarized as follows:

Input devices: The data starts at an input device, such as a keyboard, mouse, or scanner.

Input/Output (I/O) controller: The data travels to the I/O controller, which manages the communication between the input device and the rest of the computer.

System bus: The data is transmitted along the system bus, which is a collection of wires that connect the various components of the computer.

Central Processing Unit (CPU): The data is received by the CPU, which processes it according to the instructions in the software.

Output device: The processed data is then sent to an output device, such as a monitor or printer, via the I/O controller and system bus.

It is worth noting that some devices, such as hard drives or network cards, have their own dedicated controllers, and the data path may involve those controllers as well. However, the general path of data from input devices to the CPU and output devices remains the same.

Denormalization is a database optimization technique in which we add redundant data to one or more tables.

Denormalization is the process of adding precomputed redund data to an otherwise normalized relational database to improve read performance of the database. Normalizing a database involves removing redundancy so only a single copy exists of each piece of information in the database.

It is a technique used on a previously-normalized database to increase the performance of the database .In execution, denormalization is the process of improving the performance of reading a database, at the expense of losing some write performance, by adding redundant copies of data or by grouping it.

Advantages of Database denormalization:

As there is no need to use joins between tables if there is database denormalization it is possible to extract the necessary information from one table, which automatically increases the speed of  execution of any query .Additionally, this solution saves memory. Writing queries is much easier.

Denormalization is used by the database managers to increase the performance of a database. Some of its advantages are: it minimize the need for joins and it reduces  the number of tables.
