Which of the following components leads to a slow computer performance when it becomes outdated?
a.) drivers
b.) storage devices
c.) cpu
d.) alu

Drivers are not components, but rather software. Although outdated drivers could have an effect on performance in some ways, such as outdated graphics drivers affecting performance in games, they are not hardware components.

Storage devices can lead to slow computer performance once they become outdated. How fast do you think your computer would run if you were still running with floppy disks? Additionally, storage devices are susceptible to wear-and-tear, a good example being with SSDs, where bit rot can occur, where the performance of the storage chips degrade over time from use.

The CPU is a big one, and can definitely lead to slow computer performance once they become outdated. The CPU is what controls basically everything on the computer; processing and retrieving information, and an outdated one is likely to become a liability at some point.

ALUs aren't really hardware components either, but rather built in to CPUs, so this kinda ties in with the answer above.

Answer (a) with a mirror like surface;
