CompTIA Network+ Practice Test

Which kind of processor is specifically designed to perform a particular function, such as switching?

1. General-purpose processor

2. Application-specific integrated circuit (ASIC)

3. Multilayer switch

4. Embedded controller

The correct answer is: Application-specific integrated circuit (ASIC)

The choice of an application-specific integrated circuit (ASIC) is correct because ASICs are custom-designed to perform a specific task or function, such as data switching or processing. These processors are optimized for efficiency and performance in their designated role, allowing them to execute their functions faster and with lower power consumption compared to general-purpose processors. ASICs are widely used in environments where specific, repetitive tasks are performed, such as data centers and telecommunications, where the demand for speed and efficiency in switching operations is crucial. The ability to create tailored functionality makes ASICs ideal for applications requiring consistent and reliable processing within a narrowed scope. Options like general-purpose processors are designed to handle a wide variety of tasks but are not optimized for any one function. Multilayer switches serve a specific purpose but are not processors themselves; they are devices that combine switching and routing functionalities. Embedded controllers do have specific functions but are general-purpose in a niche application context and do not have the same level of task specialization as ASICs. Therefore, ASICs stand out as the ideal solution for executing designated functions with high efficiency.
