To send a selected object to the very back of all other objects, you should press:
Answer:
Ctrl + Shift + [
**Ctrl + Shift + [** (left square bracket) sends the selected object to the back of the stacking order. Conversely, `Ctrl + Shift + ]` (right square bracket) brings the object to the front.

To add shading to a drawing or auto shape object, use
Answer:
Fill color
The **Fill Color** tool is used to apply color, gradients, or textures to the interior of a shape.
3203
What happens if you release the mouse button before releasing the Shift key when drawing a square?
Answer:
The square will not be perfect
The constraint that creates a perfect square is only active while the Shift key is held down. If you release the Shift key before the mouse button, the shape is no longer constrained and may become a rectangle.

What device is used in banks to read and verify the data on cheques?
Answer:
Magnetic Ink Character Recognition
MICR (Magnetic Ink Character Recognition) is a specialized technology used by the banking industry to streamline the processing and clearance of cheques. The characters on the bottom of a cheque (like the cheque number and routing number) are printed in a special magnetic ink that can be read quickly and accurately by MICR reader devices.

Answer:
One trillion bytes
** A terabyte is a massive amount of storage. It is 10^12 bytes in the decimal system, which is one trillion bytes.
3206
One Gigabyte (GB) is equal to:
Answer:
1024 MB
** In the binary system of measurement (often used for RAM), one gigabyte is precisely 1,024 (2^10) megabytes. In the decimal system (often used for hard drive storage), it is approximately 1,000 megabytes.

Answer:
Digital computer
** High-performance computing, including supercomputers that perform billions of operations per second, is based on digital computer architecture. Digital computers provide the necessary precision and programmability for such complex tasks.
3209
A computer's ability to process different types of data, such as text, audio, and video, is an example of its:
Answer:
Versatility
** Versatility not only refers to the variety of tasks a computer can perform but also its ability to handle different forms of data. This makes computers a universal tool for information processing.
3210
Which type of computer is characterized by its use of parallel processing with thousands of processors?
Answer:
Supercomputer
** To achieve their massive computational speeds, supercomputers use massively parallel architectures, where a problem is broken down and worked on by thousands or even millions of processor cores simultaneously.
