  • CPUs run at rates of millions and billions of Hertz, megahertz(MHz) and gigahertz(GHz).
  • A clock speed of 3.5 GHz to 4.0GHz is generally considered a good processor speed.

Additional Information

• Processor(CPU)
  • A CPU is also called a central processor, main processor, or just processor, is the electronic circuitry that executing instructions comprising a computer program.
  • The CPU performs basic arithmetic, logic, controlling, and input/output operations specified by the instructions in the program.
  • The fundamental operation of most CPU's regardless of the physical form they take is to execute a sequence of stored instructions called a program. 
• Instructions cycle in Processor(CPU)
  • All CPU's follows the following steps in order to complete their operations:
    1. Fetch: The first step, involves retrieving instructions from the program memory.
    2. Decode: The instruction that the CPU fetches from the memory determines what the CPU will do, which is decoded by the instructor decoder.
    3. Execute: In this step, all the desired functions are performed as per the instructions decoded.

The correct answer is: Option 1) Virus

Key Points

• A Virus is a piece of programming code that inserts itself into another program or file to spread and cause damage (e.g., corrupting data, stealing information, or disrupting system operations).

• Malware (Option 2) is a broader term that includes viruses, worms, ransomware, etc., but the question specifies a "piece of code inserted into another program," which matches a virus more precisely.

• Spam (Option 3) refers to unwanted emails/messages, not malicious code.

• Viral (Option 4) describes content spreading rapidly online, not a harmful program.

• A virus requires a host program to attach itself to, while other malware (like worms) can operate independently.

Final Answer:
✅ Option 1) Virus

The correct answer is Douglas T Ross.

Key Points

• APT stands for Automatically Programmed Tool.
  • It was developed by Douglas T Ross.
  • It is a language that defines the tool path with respect to the part geometry and often forms the basis for post-processor generated NC files.

Additional Information

• The APT programming language is a language for defining tool paths on CNC machines.
• The APT language consists of four types of statements:
  • ​Geometry statements will be used to specify the elemental features defining the part shape
  • Motion statements are used to specify the path taken by the tool
  • Post-processor statements control the machinery, controlling coolants as well as the feeds and speeds.
  • Auxiliary statements complete the picture, specifying the part, required tools, etc.
