No matter how tech savvy you are, there are certain things every one of us has to deal with when using a computer—and we don’t always deal with them in the most efficient ways. Between the virtual theft of personal information and the material theft of laptops and desktop computers, dependency on technology can increase the risk for losses.

Here are 3 things that everyone can (and should) learn to keep their computer fast, safe, and easy to use.

Install a USB port lock

A USB port block can help bar unauthorised access to your computer’s USB ports. Port blocks are very basic – they’re pretty much just tiny plates that cover USB ports so they can’t be tampered with. Just keep in mind that if you’re going to use one, you’ll also need to have a USB lock on hand to fasten it to your computer. When a USB lock is slipped through the square hole in a port block and snapped into a USB port, the port blocker then automatically covers one of the adjacent USB ports.

Install simple computer locks and anchors

Security for computers is always a problem when equipment must be available for use by the public. While losing the machine is a real problem, you can find a find a variety of low-cost solutions – including flexible cabling systems with superglue or self-adhesive security plates. You don’t always need a fancy security system to protect your equipment. A simple security nut, bolt or screw will often do the job. You can also use security fasteners, or even a CPU Security Cabinet. This locking cabinet is for desktop computer users. Perfect for use in high-traffic workplaces where you never know who may wander in or out, take the most direct route to protecting your desktop’s CPU: lock it up. CPU Security Cabinets fit easily under your desk, where your computer tower would normally sit – the only difference is that the CPU is now completely encased in a locking enclosure that denies unauthorized access to CD and disk drives. To make authorized access easier, the enclosure has a slide-out tray that lets you pull your CPU out for maintenance in just seconds.

Use a surge protector fit for your particular type of computer and peripherals

When you put together a computer system, one piece of standard equipment you’ll probably buy is a surge protector. Most designs serve one immediately obvious function — they let you plug multiple components into one power outlet. With all of the different components that make up a computer system, this is definitely a useful device.But the other function of a surge protector power strip — protecting the electronics in your computer from surges in power — is far more important.

The main job of a surge protector system is to protect electronic devices from surges. What sort of damage does this do, and why do electronics need to be protected from them?

A power surge, or transient voltage, is an increase in voltage significantly above the designated level in a flow of electricity. If the voltage (a measure of electrical pressure)  rises above the normal, there will be a problem (think of the power of water when a water pipe bursts), and a surge protector helps to prevent that problem from destroying your computer. It prevents electrical overload into your computer – which may cause your system to malfunction, conk out, or even explode. Remember, electricity can cause fire, so think of how too much can “fry” your computer’s internal parts, wires and cables.

Do not forget that each type of computer is different from the other. What may be sufficient for one netbook or laptop may be too insufficient for an entire system of CPUs, servers, monitors and other peripherals. Choose one wisely.
