Final answer:

Searches in computer systems are faster when they are executed in memory due to the speed of access compared to slower storage devices.

Step-by-step explanation:

Searches are faster if commands are arranged so that they execute in memory rather than on slower storage devices like hard drives. The reason for this lies in the hierarchy of storage, which is organized according to the speed of access. The fastest is the CPU's registers, followed by the cache, system memory (RAM), and then storage drives. When a program is executed in memory, the CPU can quickly access and process the data without the need to read from or write to the slower hard drives. This concept is applied in various aspects of computer science, such as algorithm design, where data is often kept in memory to reduce execution time.
