RAM is measured in megabytes (MB) and gigabytes (GB), as detailed on the storage page. Just how much RAM a computer needs depends on the software it is required to run effectively. A computer running Windows XP will usually function quite happily with 1GB of RAM, whereas twice this amount (ie 2GB) is the realistic minimum for computers running Windows 7. Most mobile computers usually feature far less RAM, and indeed even desktop computers running smaller operating systems (such as some versions of Linux or Windows 98) can run very effectively with as little as 128MB of RAM in certain situations.
Central processing unit (CPU) -- The CPU, often just called the processor, is the component that contains the microprocessor. That microprocessor is the heart of all the PC's operations, and the performance of both hardware and software rely on the processor's performance. Intel and AMD are the largest CPU manufacturers for PCs, though you'll find others on the market, too. The two common CPU architectures are 32-bit and 64-bit, and you'll find that certain software relies on this architecture distinction.
Motherboard -- The primary circuit board inside your PC is its motherboard. All components, inside and out, connect through the motherboard in some way. The other components listed on this page are removable and, thus, replaceable without replacing the motherboard. Several important components, though, are attached directly to the motherboard. These include the complementary metal-oxide semiconductor (CMOS), which stores some information, such as the system clock, when the computer is powered down. Motherboards come in different sizes and standards, the most common as of this writing being ATX and MicroATX. From there, motherboards vary by the type of removable components they're designed to handle internally and what ports are available for attaching external devices.
An additional approach uses one set of fans to push air across the heat sink assembly, while a second set pulls air out of another part of the system, intermixing cooler inlet air to counterbalance the warmer air moving across the heat sink. Individual fan control can be used to monitor multiple in-system temperature sensors so air flow can be tuned for maximum cooling.
Slots are an opening in a computer where a circuit board can be inserted to add new capabilities. All personal computers contain expansion slots for adding more memory, graphics capabilities, and support for special devices. Expansion slots come in different flavours, which will be described below. An alternative explanation for expansion slots can be found here.

1. Performance times based on internal lab testing conducted in August 2015. Each task was executed and timed after the system had undergone a fresh boot so that other factors and applications didn’t affect the reported load and boot times. Actual performance may vary based on individual system configuration. Test setup: 1TB Crucial MX200 SSD and 1TB HGST Travelstar® Z5K1000 internal hard drive, both tested on an HP® Elitebook 8760W laptop, Intel® Core™ i7-2620M 2.70GHz processor, 4GB Crucial DDR3 1333 MT/s memory, BIOS Rev. F50 (5 August 2014), and Microsoft® Windows® 8.1 Pro 64-bit operating system.
Hard disk drives are the high capacity storage devices inside a computer from which software and user data are loaded. Like most other modern storage devices, the capacity of the one or more internal hard disks inside a computer is measured in gigabytes (GB), as detailed on the storage page. Today 40GB is an absolute minimum hard drive size for a new computer running Windows 7, with a far larger capacity being recommended in any situation where more than office software is going to be installed. Where a computer will frequently be used to edit video, a second internal hard disk dedicated only to video storage is highly recommended for stable operation. Indeed, for professional video editing using a program like Premiere Pro CS5, Adobe now recommend that a PC has at least three internal hard disks (one for the operating system and programs, one for video project files, and one for video media). This is also not advice to be lightly ignored if you want your computer to actually work!
To a large extent, time was called on the clock frequency war because of the difficulties encountered in cooling microprocessors as they became faster and faster. However, another driver was simply that raw processing power was starting to become a secondary concern for many purchasers. By 2005, factors such how much noise a computer makes, case style and size, and a computer's green credentials, were starting to be perceived as important. And such non-processing-power measures are increasingly driving both consumer and business computer purchase decisions today.

RAM is the easiest hardware to install when you’re building a PC. Locate the memory slots on the motherboard. Hold your memory modules on the side to avoid touching the chips and gold pins. Align the notches on the module with the ridge in the slot then firmly press the module in until it clicks. As you’re pressing, note that it takes about 30 pounds of pressure to fully install a module. Find out how to install memory in a laptop or a desktop.
When you put all the parts together, make sure you have plenty of room to keep your build organized. Be aware of static electricity as you build – it’s one of the few ways the hardware can be damaged but it’s easy to avoid. Frequently ground yourself by touching an unpainted metal surface or wear an electrostatic discharge (ESD) wrist strap to protect your system’s components from the static electricity that’s naturally present in your body. It’s also helpful to keep a can of compressed air to remove any dust or fine debris from the interface as you’re installing the processor, memory, and SSD. 
A flash drive is faster and uses less power than a hard disk. However, per byte, flash is significantly more expensive than hard drive storage. Flash has been getting cheaper, so it may take over niches at the expense of hard drives. Flash is much slower than RAM, so it is not a good replacement for RAM. Note that Adobe Flash is an unrelated concept; it is a proprietary media format.
When using computer hardware, an upgrade means adding new hardware to a computer that improves its performance, adds capacity or new features. For example, a user could perform a hardware upgrade to replace the hard drive with a SSD to get a boost in performance or increase the amount of files that may be stored. Also, the user could increase the RAM so the computer may run more smoothly. The user could add a USB 3.0 expansion card in order to fully use USB 3.0 devices, or could upgrade the GPU for extra rendering power. Performing such hardware upgrades may be necessary for older computers to meet a programs' system requirements.
Other computer output hardware includes devices such as speakers (which can cost from a few pounds to several hundred) as well as Ipods and other music players that millions of people now use to extract music from their PC to listen to elsewhere. As with digital cameras (some of which are also music players!), in terms of a paradigm shift this is highly significant in that a personal computer is rapidly becoming a "digital hub" into which many of our most used hardware devices are only ever temporarily connected. In turn, one could argue that our computers are increasingly with us all of the time in the form of those hardware devices that travel with us, but which functionally depend on at least an occasional interaction with a PC and often a website.
Computer hardware is a general term to describe all the physical parts of a computer system. A typical computer system consists of a computer case, a power supply unit, a motherboard, a central processing unit (CPU), main memory, and a hard disk drive. Input devices include a keyboard, mouse, microphone, video camera, and image scanner. Output devices include a monitor, speakers, and a printer.
When the first microcomputers were introduced in the late 1970s, and in particular when the IBM PC was launched (in 1981 in the USA and 1983 in the UK), the computer industry was dominated by hardware. This was because most of the money spent on a computer system went on hardware, with a direct trade-off existing between processing power and overall system cost. The exact hardware specification was usually also critical. Today, however, neither of these points remains the case.
USB, short for Universal Serial Bus, is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices.[1] A bus is a communication system that transfers data between components inside a computer, or between computers.[2]
So, I wanted to know for my own setup what should I do. If it’s better for my utilisation or now to have both setups which will be used in the same Case (Corsair 1000D) one with a regular ATX (ex: Threadripper) and the Second one with a mini ATX (ex: I9 9900k) or a single massive setup. Planning for a 6000euros ~ 6826,52$ (living in France… max for the case) and 1500e for 3 displays.
The term supercomputer does not refer to a specific technology. Rather it indicates the fastest computations available at any given time. In mid 2011, the fastest supercomputers boasted speeds exceeding one petaflop, or 1 quadrillion (10^15 or 1,000 trillion) floating point operations per second. Supercomputers are fast but extremely costly, so they are generally used by large organizations to execute computationally demanding tasks involving large data sets. Supercomputers typically run military and scientific applications. Although costly, they are also being used for commercial applications where huge amounts of data must be analyzed. For example, large banks employ supercomputers to calculate the risks and returns of various investment strategies, and healthcare organizations use them to analyze giant databases of patient data to determine optimal treatments for various diseases and problems incurring to the country.
