Technology is complex, and most people use it daily without needing to understand exactly how it works. This knowledge gap creates fertile ground for myths — some that began as outdated advice that was once partly true, some that are misunderstandings of how systems work, and some that are simply repeated until they seem credible. Knowing the truth helps you make better decisions and stop doing things that do not actually help.
Myth: More RAM Always Makes Computers Faster
RAM (Random Access Memory) allows your computer to hold active processes in quick-access storage. If your computer regularly runs out of RAM — visible as slowdowns when opening multiple large applications — adding more makes a real, measurable difference. However, if you already have enough RAM for your typical workload, adding more produces no practical improvement.
A computer with 8 GB of RAM being used for web browsing, documents, and video calls will not perform noticeably faster with 16 GB. The real bottleneck in most modern computers is processor speed, storage speed (a traditional hard drive versus a solid-state drive), or network bandwidth — not RAM quantity.
Myth: Closing Apps Always Saves Battery
On modern smartphones, fully closing an app and relaunching it later frequently uses more battery than leaving it suspended in the background. When an app is suspended, the operating system freezes its state and it consumes almost no resources. Relaunching the app requires the device to rebuild it entirely in memory, which is more energy-intensive than resuming a suspended process.
The habit of aggressively closing all background apps originated in the early smartphone era when operating systems were less sophisticated at managing memory. On modern iOS and Android, the system manages background apps intelligently. Manually closing apps interferes with this process rather than improving it.
Myth: Restarting Your Computer Is Unnecessary
Some people run their computers for weeks or months without restarting. This is rarely the best approach. Restarting clears temporary files that accumulate over time, applies pending updates that cannot take effect while the system is running, releases memory that applications have failed to free, and resolves minor software conflicts that build up during extended operation.
A regular restart — roughly once a week for typical use — keeps the system running cleanly. This is particularly important on Windows, where security and feature updates specifically require a restart to complete installation. Deferring restarts keeps known vulnerabilities active longer than necessary.
Myth: Third-Party Drivers Are Always Better
Third-party driver updater utilities are promoted as an easy way to keep all system drivers current automatically. In practice, these tools frequently install incorrect, incompatible, or unverified drivers sourced from generic databases rather than manufacturer repositories. Some are classified as potentially unwanted programs, and a small number are outright malicious.
Manufacturer drivers, downloaded directly from the company's official website, are the authorised and tested version for each specific device. They go through a quality assurance process that third-party tools completely bypass. Windows Update and macOS Software Update include driver packages that have been verified for compatibility with the respective operating system.
Myth: More Expensive Printers Are Always Better
Price and suitability are not the same thing. A printer is only "better" if it fits your specific needs better — and the most expensive printer in a range may include features, paper handling capacities, or print volumes that are entirely irrelevant to how you will actually use it.
What matters is whether the printer matches your use case: the types of documents or images you print, the volume per month, the running costs, and the build quality relative to how long you expect to keep the machine.
