Let's denote the speed of the newer personal computer as $x$ gigahertz. According to the problem, the operating speed of the older personal computer is $50$ gigahertz, and this is one-fourth the speed of the newer model. Mathematically, we can represent this relationship as: \[\frac{1}{4} \times x = 50\] Now, we solve for $x$, the speed of the newer personal computer: \[\frac{1}{4} \times x = 50\] To isolate $x$, we multiply both sides of the equation by $4$: \[x = 4 \times 50\] \[x = 200\] So, the speed of the newer personal computer is $200$ gigahertz.
