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.

A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. An SSD emulates a hard disk drive, thus easily replacing it in any application. SSDs have begun to appear in laptops because they can be smaller than HDDs. SSDs are currently more expensive per unit of capacity than HDDs which is why they have not caught on so quickly.
Alongside clock speed, the architecture of a processor is the most important factor to determine its performance, and refers to its basic design and complexity. Some processors are simply more sophisticated than others, with Intel (for example) producing "basic" processors called Celerons and Pentiums, as well as more powerful processors under its "Core" processor family. The later include the Core 2, Core i3, Core i5 and Core i7, with the last of these being the most powerful.
The power supply as its name might suggest is the device that supplies power to all the components in the computer. Its case holds a transformer, voltage control, and (usually) a cooling fan. The power supply converts about 100-120 volts of AC power to low-voltage DC power for the internal components to use. The most common computer power supplies are built to conform with the ATX form factor. This enables different power supplies to be interchangable with different components inside the computer. ATX power supplies also are designed to turn on and off using a signal from the motherboard, and provide support for modern functions such as standby mode.

In broad terms, the performance of a computer depends on four factors: the speed and architecture of its processor or "central processing unit" (CPU), how much random access memory (RAM) it has, its graphics system, and its internal hard drive speed and capacity. Also of importance to most users will be the specification of its Internet connection. Most computer users -- and in particular those working with a lot of photographs, music files or videos -- should also think about the most suitable storage devices they will need in order to keep and back-up all of thier valuable data.
The next two items share the same function but are built differently. A Hard Drive uses a disk and magnets to write data on to the disk that will permanently store information, assuming the disk itself does not get damaged for other reasons.  Hard Drives are older compared to Solid State Drives and are significantly cheaper than SSDs. Solid State Drives work off of flash memory, unlike a hard drive they have no moving parts and everything works electronically. Examples of devices that work on flash memory that you are possibly familiar with are your usb storage devices/ “flash drives”, video game memory cards, or an SD card that most cameras use. SSDs read data much faster but due to the technology being newer are more expensive. If you’re building a computer that will not require a lot of storage you it would be prefferable to buy an SSD, however Hard Drives are much less expensive if you plan on storing more than 250Gigabytes of information.
Another important part of the computer is the motherboard. Although often overlooked, its job is massive. It determines the bus speed, the amount of memory, how many expansion cards allowed, and the types of processors compatible with the system. When looking for a motherboard consider the processor socket, form factor, front-side bus speed, and RAM socket.
In effect, modern graphics cards have become dedicated computers in their own right, with their own processor chips and RAM dedicated to video decoding and 3D rendering. Hardly surprisingly, when it comes to final performance, the more RAM and the faster and more sophisticated the processor available on a graphics card the better. This said, top-end graphics cards can cost up to a few thousand dollars or pounds.

According to the United States Environmental Protection Agency only around 15% of the e-waste actually is recycled. When e-waste byproducts leach into ground water, are burned, or get mishandled during recycling, it causes harm. Health problems associated with such toxins include impaired mental development, cancer, and damage to the lungs, liver, and kidneys.[11] That's why even wires have to be recycled. Different companies have different techniques to recycle a wire. The most popular one is the grinder that separates the copper wires from the plastic/rubber casing. When the processes is done there are two different piles left; one containing the copper powder, and the other containing plastic/rubber pieces.[12] Computer monitors, mice, and keyboards all have a similar way of being recycled. For example, first each of the parts are taken apart then all of the inner parts get separated and placed into its own bin.[13]

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.]
Blu-ray is a newer optical disc storage media format. Its main uses are high-definition video and data storage. The disc has the same dimensions as a CD or DVD. The term “Blu-ray” comes from the blue laser used to read and write to the disc. The Blu-ray discs can store much more data then CDs or DVDs. A dual layer Blu-ray disc can store up to 50GB, almost six times thecapacity of a dual layer DVD (WOW!). Blu-ray discs have similar devices used to read them and write to them as CDs have. A BD-ROM drive can only read a Blu-ray disc and a BD writer can read and write a Blu-ray disc.

The size of your hard disk drive, or HDD, determines how many applications, photos, videos, MP3s, documents and other items you can store on your computer and access daily. Here, you have the option of a hard drive or a solid-state drive for storage. Solid-state drives, or SSDs, are preferable in some cases because they have faster loading times than HDDs. However, SSDs are costlier. Some computer enthusiasts prefer both installed in their PC, offering the best of both options and it's easy to switch between them. Hard drive sizes range from less than 250GB and more than 2TB, with 500GB being a middle range. Additionally, it is easy to increase hard drive space using portable HDDs.
DVDs (digital versatile discs) are another popular optical disc storage media format. The main uses for DVDs are video and data storage. Most DVDs are of the same dimensions as compact discs. Just like CDs there are many different variations. DVD-ROM has data which can only be read and not written. DVD-R and DVD+R can be written once and then function as a DVD-ROM. DVD-RAM, DVD-RW, or DVD+RW hold data that can be erased and re-written multiple times. DVD-Video and DVD-Audio discs respectively refer to properly formatted and structured video and audio content. The devices that use DVDs are very similar to the devices that use CDs. There is a DVD-ROM drive as well as a DVD writer that work the same way as a CD-ROM drive and CD writer. There is also a DVD-RAM drive that reads and writes to the DVD-RAM variation of DVD.
Adding memory (RAM) is one of the fastest, easiest, and most affordable ways to amplify the performance of the computer you’re building because it gives your system more available space to temporarily store data that’s being used. Nearly every computer operation relies on memory – that includes having several tabs open while surfing the Web, typing and composing an email, multitasking between applications, and even moving your mouse cursor. Even background services and processes, like system updates, can draw from your RAM and that’s why it’s important to have as much memory as possible. The more things you’re doing, the more memory you need.
