all-in-one pcs

The most obvious advantage of an all-in-one PC is probably the look. All PC components are installed behind the screen and are in a single housing, which eliminates the need for cables between the monitor and the PC.
If you also connect your mouse and keyboard via Bluetooth and set up Internet access via WLAN, you only need one cable - the one to the power outlet. Aside from the fact that you don't have to deal with a tangle of cables, you also get a nicer look and avoid the possibility of errors caused by incorrectly connected cables.
Another plus is that you can assemble and disassemble the PC in a few simple steps. So you can easily stow it away and move it flexibly to another place. This is especially advantageous if you don't have a permanent workplace or if you have to move to a different location. The smaller space requirement is also particularly advantageous in this context.
The computers also work with power-saving components and therefore cause less noise than conventional desktop PCs. Many all-in-one PCs can be operated via touchscreen. Overall, these PCs offer a very good overall performance and are often even suitable for current 3D games.

The displays of the all-in-one PCs are usually at least 24 inches, have a screen diagonal of 60 centimeters and are thus significantly larger than notebooks.
Some devices even come with 27-inch displays and a screen diagonal of 68 centimeters. Most screen PCs also display content in Full HD (1920 x 1080 pixels), which is not a bad choice, especially for office programs.
However, if you want to watch 4K videos or edit photos in detail, you'll be better off with a higher-resolution display, like the one on the latest iMac. The 27-inch models, which you can find not only from Apple, but also from HP or Lenovo, have a higher price, but also a higher resolution.

If you often work with many programs at the same time, you should pay attention to the size of the RAM and preferably choose a model with 16 gigabytes. However, some all-in-one PCs are limited or impossible to upgrade.
Most all-in-one PCs have an SSD, i.e. a "solid state drive", in which the storage medium does not have any moving parts. When transferring data to an external SSD, up to 360 megabytes or more can often flow through the USB cable.
If you want to expand your memory and your device allows it, I recommend a fast SSD for more speed, which you can get with a terabyte storage capacity for little money. A USB hard drive in 2.5-inch format, which does not require a power supply and which you can even find with four terabytes, is also recommended.

Thanks to DVD and Blu-ray drives as well as the right burner, all-in-one computers are also perfect as an inexpensive multimedia PC. However, it depends on the model and the manufacturer which drives the device has.
On Lenovo machines, the DVD burner is often located behind the display, so you won't see it at first glance. This drive extends to the side.

With most all-in-one PCs, a power cable is sufficient for operation, because mouse and keyboard often work with wireless technology. However, many cables on the desk are also possible, because the PCs bring significantly more ports than most notebooks. Most of them are located on the back of the device. This is very useful because the cable does not run across the desk when you connect accessories like a multifunctional device or an external hard drive to the PC.
For quickly plugging in a USB stick, however, the ports on the back are a bit awkward. USB ports on the front or side of the PC are much easier to use.
Almost all high-quality models offer two options for connecting to the home network: On the one hand, you can connect wirelessly via WLAN (WiFi) or wired (LAN) via the network jack(s).
Usually, these PCs also come with a keyboard and a mouse that you can connect directly via Bluetooth. Often, other components such as an integrated microphone, speakers or a webcam are also integrated into the case.
You can even connect your PC to your flat-screen TV via an optional HDMI port and experience movies in cinema format this way.

Yes, there are even special All-In-Ones for users who mainly want to play games with their PC. These gaming all-in-one PCs are characterized by powerful processors and very good graphics cards.
Often, the RAM (memory for temporary data) is also very high in these specimens. When gaming, it hardly makes a difference in performance whether you use DDR3 or DDR4. I still recommend you to use DDR4 RAM if your processor supports it. The DDR4 RAM differs in the number of contacts the memory has. The increased number of contacts compared to DDR 1, 2 or 3 allows for faster transfer rates.
Unfortunately, there are no gaming models with a battery, because they need so much power that no battery would really be able to withstand it for long.

Yes, an All-In-One with battery mainly contains notebook components. The advantage is that they are optimally coordinated and work perfectly together. You can choose from almost any operating system: There are models from Apple with OSX, but also variants with Chrome, Windows or Linux.
Models with a battery are especially practical. For example, you can lay it flat on the table and use it as a giant tablet or with a keyboard as a laptop. However, these models are not intended for completely mobile use, but rather for use in your own four walls.
All-in-one PCs with battery are really well suited for private users who do not often upgrade their PC, because that is not really possible with these models.
