Step 1
Virus
Answer
A virus is a malicious program or piece of code that attaches itself to other software or files on a computer. When executed, it replicates itself and can infect other programs without the user's consent. Viruses are typically created with the intent to corrupt, steal data, or damage the user's system. The impact of a virus can range from minor annoyances to significant harm, such as the loss of critical files or complete system failures.
Step 2
CNC laser cutter
Answer
A CNC (Computer Numerical Control) laser cutter is a precision tool that utilizes a laser beam to cut through materials. Laser cutters are known for their high accuracy and are used in various applications, such as cutting and engraving materials like plastics, glass, and metal. The design process begins with a 2D vector drawing, which is then sent to the machine. It is important to manage the exhaust systems properly to ensure safety, particularly when dealing with materials that may produce hazardous fumes, like plastics.
