The oldest form of computer displays had large cathode-ray tubes. These had a large display size, and main components like the monitor and other input devices. The new generation PC comes with a smaller monitor size; computer manufacturers started to integrate the monitor with computer case to make an all-in-one PC. These first all-in-one computer systems were large and expensive as compared to other computers.
The most successful all in one is Apple iMac. These PC design used the cathode-ray monitor and other parts integrated inside it. Many manufacturers tried similar designs, but could not able to make it. With the usage of LCD monitors and other mobile parts which are converted into smaller components and with increasing power, the size of the all-in-one computer system starts decreasing. Nowadays computer components can be easily assembled with the LCD panel.
All-In-One PC Vs. Desktop PCs
All-in-one computers are a compact and smart version of a desktop computer system with style enhancement. They are advance with the same features. The main difference between the two is the number of components. All-in-ones comes compact and have a single arrangement with an integrated display with case and the desktop have computer case and a separate monitor. This feature makes all-in-one computer system a smaller platform than desktop systems.
There are many other advantages of buying a desktop over an all-in-one PC as small size and low power requirement and with less heat-generating components make them better. All-in-one PCs have small design components such as processors, drives, and memory. These compact structures make the all-in-one PC smaller, but it also affects its overall performance. These laptop components perform slower as compare to desktop. For users, these low power mobile components will be faster enough to cope with their requirements.
The major challenge is the up-gradation of these computers. The customer can easily open many desktop computers for repairing or installing upgrades; these compact systems does not allow easy accessibility to the components. The design restricts the methods to replace easily; the only access is for memory up-gradation. With the development of external connectors such as USB 3.0, we can upgrade internal parts as well. For some components such as the graphics processor, the up-gradation is very difficult.
All-In-Ones Vs. Laptops
With the evolution of laptops a few years ago, the comparison of all in PC with them is almost one-sided. The advancement which met with the computer is high as compared to all in one PC.
The performance level of both laptop and all in one is the same as all-in-one PCs uses similar components as laptops. The real compelling advantage is screen size of the all in one PC. While notebooks come with 17 inches and smaller sizes, you can opt for all-in-one PCs with screen sizes between 20 and 27 inches.
Laptops are more portable and easy to use; the inbuilt power back up storage makes them much better than the all-in-one.
