Cold
booting, also known as hard booting, is the process of starting up a
computer that is completely turned off. It begins when the user presses
the power button, which activates the computer’s hardware and loads the
operating system from scratch. This type of booting is usually done when
the system is initially powered on or after a complete shutdown. It
refreshes the computer’s memory and performs all the necessary startup
checks (POST, Power-On Self-Test), ensuring the system starts in a clean
and stable state.
(3cii)
Warm booting, also known as soft
booting, is the process of restarting a computer without turning off the
power. It is usually done using the Restart button or pressing Ctrl +
Alt + Del on the keyboard. During warm booting, the computer skips some
hardware checks and reboots faster than a cold boot. This method is
commonly used when software updates require a restart or when the system
freezes and needs to be refreshed without a full shutdown.

Database Management System (DBMS) is software that allows users to

The
Knife tool in CorelDraw is used to cut or split an object into two or
more separate parts. It allows designers to divide shapes, texts, or any
drawn object along a freehand, straight, or Bézier line. This is
especially useful when creating complex shapes or modifying designs by
trimming off parts of an object. After using the Knife tool, each
resulting section can be filled, colored, or edited independently,
making it very useful for creative and advanced graphic design work.
(5bii)
The
Polyline tool is a drawing tool used to create lines composed of both
straight and curved segments in a single, continuous path. Unlike the
regular line tool that draws only straight lines, the Polyline tool
allows the user to click and drag to combine straight points and smooth
curves freely. This makes it ideal for drawing complex shapes, outlines,
or freeform illustrations with precision and flow. It's a very
versatile tool in CorelDraw that blends the functions of multiple line
tools into one.
