ALL IN ONE PC?

An all-in-one computer provides everything a consumer needs in one box. The monitor is bonded with
the PC hardware, banishing the need for a bulky desktop.

A keyboard and mouse is usually included with the bundle as well.

All-in-one PCs are available in a variety of styles, but most aim towards the premium market.

It’s not unusual to see 1080p or even 2560 x 1440 display resolution, as well as high-end Intel Core 
processors.

A quality soundbar helps many of these products serve as multimedia machines.

Consumers pay for this style and convenience with performance.

These computers don’t pack the processors or video cards some enthusiasts demand.

The all-in-one form factor was popular during the early 1980s for computers intended for professional use such as the Kaypro IIOsborne 1TRS-80 Model II and Compaq Portable. Many manufacturers of home computers like Commodore and Atari included the computer's motherboard into the same enclosure as the keyboard; these systems were most often connected to a television set for display. 

Apple has manufactured several popular examples of all-in-one computers, such as the original Macintosh of the mid-1980s and the iMac of the late 1990s and 2000s. By the early 2000s, many all-in-one designs were using flat panel displays, and by late 2012 some all-in-one models also included touchscreen displays to accommodate Windows 8.






 DESKTOP PC?

desktop computer is a personal computer in a form intended for regular use at a single location desk/table due to its size and power requirements, as opposed to a laptop whose rechargeable battery and compact dimensions allow it to be regularly carried and used in different locations. 

The most common configuration is a computer monitor, keyboard and mouse, and a case that houses the main components of the PC, namely the power supply, motherboard, hard drive, optical drive, and previously the floppy drive. 

The form factor of the case is typically an upright tower or (horizontal) desktop.

 All-in-one computers, that integrate the monitor and main PC components in one unit, are often categorized under the desktop computer umbrella, particularly if they require an external power source and separate keyboard/mouse. 

The desktop category has also encompassed home computers and workstations.


A History of Personal Computers



The Electronic Numerical Integrator Analyzer (ENIAC) is usually regarded as the first electronic computer. Built in the United States at the University of Pennsylvania, the machine was used during World War II for ballistic calculations for the U.S. military. Weighing in at 30 tonnes, the EINAC occupied 186 square metres and cost US $500,000 to manufacture, which is well over US $6.5 million in 2013.
Although computers made their debut in the 1940s, it was not until the 1970s that the machines truly began to spread from the government to the public sector. That decade, technology enthusiasts could buy, assemble, and program the components of these microcomputers themselves. At the time, however, early PCs were sought more for their novelty than functionality, as common uses included only basic games and mathematical calculations.
In 1975, following the adaptation of BASIC programming language, Bill Gates and Paul G. Allen founded Microsoft. Two years later, Steve Jobs and Stephen Wozniak introduced the first Apple computer. By 1982, personal computers had become so indispensable that Time magazine named the PC its "Man of the Year."

ALL-IN-ONE PC vs DESKTOP PC


Advantages


The all-in-one is relatively compact and easy to set up; just plug in the keyboard, mouse and power supply, and you’re up and running. The simple, one-box design is also a lot more attractive than a bulky, noisy PC unit and a separate monitor, with chunky cables running between the two.
As with a desktop, however, you get a full-sized screen and mouse and keyboard, which make the all-in-one more comfortable to use over long periods, and better equipped for watching videos or doing creative work. An all-in-one will usually have better sound than a laptop, and a greater range of connections for hooking up cameras, printers, external hard drives and other devices.

Disadvantages


Of course, the all-in-one also has some negative qualities. On the other side, all-in-ones still use more power than a laptop, and can be folded away when the day’s work is done. Those stylish, slimline designs also come at a price. An all-in-one PC invariably costs more than the equivalent desktop PC and monitor, bought separately.
With that said, the combination of style, comfort and convenience still makes an all-in-one a great home PC. If you’re in the market for one, there are a few things you need to think about.

ALL-IN-ONE vs. DESKTOP PC

All-in-one computers are really just a style of desktop computer system. They still have the same requirements in terms of features and function. The only difference is the number of components. All-in-ones have a single box that is the display and computer versus the desktop that is comprised of the computer case plus a separate monitor. This gives the all-in-one computer system a smaller overall profile than a desktop computer system.
One might counter by bringing up the latest small form factor computers such as the Apple Mac Mini. These new class of extremely small computers that can easily sit beneath or behind a standard desktop display. The all-in-one PC still has an advantage over these systems in the number of required cables. Since the monitor is integrated into the system, there isn't a need for a monitor cable or separate display power cord. This reduces the clutter on, underneath or behind a desk.
Desktop do have some distinct advantages over the all-in-one PCs though. Due to their small sizes and need for lower power and less heat generating components, many all-in-one PCs feature mobile designed components including processors, memory and drives. All of these help make the all-in-one small but they also hinder the overall performance of the system. Typically these laptop components will not perform as well as a traditional desktop. Of course for the average user, many of these low powered mobile parts will often prove to be fast enough.
Another issue that all-in-one computers have is their upgradability. While most desktop computer cases can be easily opened by the consumer to install replacements or upgrades, all-in-one systems tend to restrict access to the components due to their small nature. This typically only limits the systems to having their memory upgraded. With the rise of high speed external peripheral connectors such as USB 3.0, internal upgrade options are not as critical as they once were but still still make a huge difference when it comes to some components such as the graphics processor.
