    The 650 was clocked at a frequency of 125 kHz. [14] It could add or subtract in 1.63 milliseconds, multiply in 12.96 ms, and divide in 16.90 ms. The average speed of the 650 was estimated to be around 27.6 ms per instruction, or roughly 40 instructions per second. [15]

    The IBM 650. Announced in 1953, the IBM 650 Magnetic Drum Data Processing Machine was the world’s first mass-produced computer — and the first computer to generate a significant profit.

    • PC Settings. Sometimes you PC settings can get in the way of optimal performance. Take your power settings, for example. Switching to high performance can give your PC the boost it needs to run faster.
    • Slow on Startup. If your PC is only slow during boot up, then it’s possible that it’s being bogged down by applications that launch on startup. Right-click Start and select Task Manager.
    • Slow Internet. If you find that only the internet is running slow, turning off OneDrive could actually help. OneDrive works by constantly syncing your files to the cloud which can bottleneck your internet speed.
    • Full Hard Drive. Windows 10 has a feature called Storage Sense. It automatically deletes files that you don’t need so storage never causes your computer to slow down.
    • Evaluate Your Needs. Ideal computer specifications are determined by your specific use case. For example, how fast your PC needs to be depends on what you plan to do with it.
    • Desktop Processors. While there are many different desktop processors, or CPUs, most come from just two manufacturers: AMD and Intel. Intel processors generally offer better performance, but they are more expensive than AMD processors.
    • Memory. Memory, or RAM, plays a big role in the speed and performance of a PC. The higher the RAM, the better the performance. Experts recommend at least 8 gigabytes of memory, but 16 GB offers better performance.
    • Hard Drives. While some desktop computers still rely on hard disk drives, most newer PCs ship with solid-state drives for storing and caching data. SSDs are preferable since they're faster, more efficient, and more durable than HDDs.
