All-in-one computers are just like desktop computers only they are more compact. Instead of having three components: the monitor, CPU and the input devices, a mini computer only has two or one because the CPU is already inside the monitor’s case, or within the keyboard.
These kinds of computing devices are easy to move around and take up less space than conventional computers. They are generally more portable than conventional desktop PCs and most of them even have a special carrying case included in the package or are built into the unit itself. Wiring and physical installation is also easier because you only have to connect the keyboard to the unit and plug it into a power source.
The biggest advantage that all-in-one computers have over conventional PCs is the size. They can fit in areas that don’t really have much space. If you want to save up on desk space in your office, getting a compact computer will work better because it frees up the space where the system unit should have been.
Contrary to popular belief, individuals who use smaller computers are able to upgrade the memory and storage capacity of their unit, minimizing the need for external storage hardware.
More advanced users who need more computing power can easily use additional tools like external CD/DVD drives. They can also install different kinds of software to get more out of their mini PC. However, for a consumer who only needs basic stuff like word processing, filing, storage and Internet connectivity, a mini computer is an ideal option.
