Searching for Files using a Question Mark (?)
Question mark replaces a single character or symbol. It represents only one character, so it
searches for single character. For example, when we type in?ia in the search box of File Explorer,
it will display only files or folders whose names have in as the first two characters and ia as the
last two characters. The ? (question mark) acts as a wildcard, representing any single character
in between.
Step 1: Open the File Explorer and type in?ia in the search box.
Step 2: The File Explorer displays the searched files and folders.

A computer is an electronic device capable of processing data, performing calculations,
storing information, and executing user-provided tasks.
A computer accepts input, processes data, generates output, and stores information.
Computers are essential for learning, healthcare, communication, business, entertainment,
travel, and everyday tasks like online shopping and managing devices.
Key features of a computer include speed, efficiency, storage, accuracy, automation,
diligence, and memory handling.
The computer consists of hardware (physical parts like input, processing, output, and
storage devices) and software (programs that control and perform tasks).
Devices like keyboards, mouse, touch screens, microphones, and scanners enable users
to provide data to the computer.
Tools like monitors, printers, speakers, and projectors display or produce the processed
results for users.
The Input-Process-Output (IPO) cycle transforms raw data into useful information using
input devices, the CPU for processing, and output devices.
Techniques like deleting unnecessary files, clearing temporary data, uninstalling unused
programs, and using tools like Disk Cleanup help optimise storage space.
Booting starts the computer, loading the OS, and preparing it for use, while proper
shutdown ensures safe closure of programs and system power-off.
