Computers are part of everyday activities like studying, shopping, communication, and
                       entertainment.
                        A computer is a device that  processes information using two  main parts:  hardware
                       (physical parts) and software (programs).
                        Computers work quickly, accurately, and can store large amounts of data.
                        Computers  help  us  learn,  connect  with  others,  do  homework,  create  projects,  find
                       information, and more.
                        Computers do four  main things: take  in information  (input),  process it, show results
                       (output), and store data.
                        IPO stands for Input-Process-Output, where input is given, processed by the CPU, and
                       shown as output.
                        Computers are made up of different components for input, processing, output,  and
                       storage.
                        Hardware includes input devices (keyboard, mouse), output devices (monitor, printer),
                       and storage devices (hard drives, SSDs).
                        Data storage is measured in units like bytes, kilobytes (KB), megabytes (MB), gigabytes
                       (GB), and terabytes (TB).
                        Software is a set of instructions that enables a computer to perform tasks, with apps on
                       mobile devices being examples.
                        Application  software  are  designed  for  user-specific  tasks,  such  as  word  processors,
                       spreadsheets, and web browsers.
                        Disk Management is a Windows tool for managing storage devices, including partitioning
                       drives.
                        File Explorer is a tool to access and manage files and folders on Windows, enabling
                       actions like moving and renaming files.
                        Recycle  Bin  temporarily  stores  deleted  files,  allowing  for  restoration  or  permanent
                       deletion.
