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.

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 'copied from e x a m p l a z a s . c o m free' 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.

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.

The Polyline tool is a drawing tool used to create lines composed of both 'copied from e x a m p l a z a s . c o m free' 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.
