There are many choices in the computer market with different models and designs all created for different benefits and uses. Computer manufacturers design systems made for all possible uses with a variety of features to perform any type of computing task. There are also different models and designs available and a whole mobile sector that makes it easy to compute from anywhere without being tied to a plug.
As far as desktop systems go there are two main designs, the all-in-one and the traditional desktop computer system. Each has its own benefits and pros and cons. The choice sometimes comes down to how and for what the computer will be primarily used.
The all-in-one model is where the monitor and CPU are part of one unit so you do not have a CPU tower and a separate monitor that takes up more space as is the case with the traditional desktop system. The all-in-one eliminates the bulky and messy cables and connection wires that are part of the traditional set up.
There are some important differences between an all-in-one desktop computer and a traditional desktop computer. The traditional desktop is big and bulky. It can take up a lot of room, especially when you have a limited amount of space, with the CPU tower, plus the monitor as well as other peripherals, such as a printer or scanner.
The all-in-one also has no cables except for the power cord and peripheral cables and so it creates much less clutter under your desk. Overall the all-in-one desktop is able to provide you with much more space because of its compactness and size, which makes it much more space friendly. Another benefit of them is the fact that they come with notebook computer components, which require less power and generate less heat and so they save on power, which saves some money.
There are some cons with the all-in-one models. As opposed to the traditional desktop computer, which has plenty of room for expansion such as adding a hard drive or more memory, the compactness of the all-in-one leaves little room for it. So while the all-in-one is more efficient, it is less upgradeable. But unless you need a lot of features or you are a power user, the all-in-one because is a great choice for aesthetics, space and power saving benefits. However, for extreme gamers or power users the traditional system is a better choice.
