Then there’s another choice you have to make. You can buy either a hard drive or a solid-state drive (SSD). Some sources recommend combining a lower-end SSD with a hard drive for the best of both worlds. But if you can cover your storage needs with an SSD alone, it may be helpful to go this route, as these drives can halve loading times, no problem.
Display screens remain the dominant form of computing output peripheral, with most new modern desktop displays being flat panels of between 15" and 19" in diagonal. However, far more bulky cathode ray tube (CRT) monitors are still favoured by some in high-end graphics work where absolute colour control is required. For other types of visual output (especially in education and training) video projectors are now also in widespread use. Whilst most flat computer displays are currently based on TFT (thin-film transistor) LCD (liquid crystal display) technology, over the next decade these are likely to be replaced with OLED (organic light emitting diode) screens as already used on some mobile phones and media players. [Note that OLED screens should not be confused with LED-backlit LCD screens however much some manufacturers try to confuse potential buyers otherwise. LED-backlit screens are very nice indeed. OLED are amazing, if currently incredibly expensive.]
The motherboard is the body or mainframe of the computer, through which all other components interface. It is the central circuit board making up a complex electronic system. A motherboard provides the electrical connections by which the other components of the system communicate. The mother board includes many components such as: central processing unit (CPU), random access memory (RAM), firmware, and internal and external buses.
If you’re not a gamer, then you might be able to skip the high-end graphics card. Modern CPUs, like the Intel Core i7 Kaby Lake, can handle almost all graphic needs that a business user might have. Regardless of your specific use case, it’s not a bad idea to invest in a large amount of memory to keep your machine running smoothly, especially when multi-tasking.
