Some of the disadvantages of computers include an over-reliance on technology, vulnerability to cyber-crime, increased potential for distraction and various negative social effects. While computers offer numerous benefits, many of the conveniences they create also lead to potential problems.
Computers make it extremely easy to store and access data, but their increasing use has led to an extreme level of dependence on them, which can create a number of problems if and when computers malfunction. A power outage can render entire businesses or institutions essentially inoperable without the use of computers. Data that is stored on computers can also be lost permanently if not backed up properly, and back up methods are not entirely dependable.
In a similar vein, personal data stored on computers is often extremely vulnerable to digital theft. Data regarding bank accounts, credit cards, social security numbers and more is commonly transmitted online, and security protocols to protect this data are not always effective.
Computers also create the added potential for distraction. The sheer amount of content on the Internet makes it possible to spend almost limitless time browsing blogs, playing games or chatting with friends. This can dramatically detract from productivity, whether it's at work, in school or at home. Computers can also hinder social interactions. Many users are often distracted from real life interactions by the draw of computers, diminishing social relationships.
