Desktop Crash Course
I know basic PC which is enough to build a desktop PC. Basic PC is enough knowledge to research what kind of desktop PC, what hardware to buy, what brand name, and cost. Hardware changed from 2015 and 2019. Researching takes patience. Shopping around to compare prices takes time. Timing is a factor when the purchase the hardware. Most of the hardware was purchased on Black Friday 2019. Financial planning is required to budget how much to spend. Likewise buying a desktop. Here is a crash course on desktop hardware I researched.
Random Access Memory (RAM). RAM allows the motherboard to quickly store data and access data without going through the hard drives. It stores data when it is needed. Faster frequency leads to faster memory processing the data. Frequency takes priority over latency. Latency is the time between a system command entered and executed. The lower the latency, the faster the memory moves onto the next process. CAS is latency. Want low number CAS latency. Start with 16GB RAM. 32GB and beyond are for enthusiasts and purpose-built workstations. Upgrading RAM is easy when RAM is frequently maximized.
Graphics Processor Unit (GPU) or Graphics Card. The GPU translates information from your PC into images. The more powerful GPU processes information faster and displays better visuals. Confirm the case has room for the GPU. Look at the GPU's length, height, and thickness. GPUs comes in half-height or slim, single-slot, dual-slot, and triple-slot. Most gaming GPUs occupies dual-slot. Nvidia uses CUDA Cores. Radeon uses Stream Processors. The two numbers are the number of processing units in the GPU like the number of cores in a CPU.
Power Supply Unit (PSU). A power supply provides electricity to the desktop's hardware. There is no additional cost when the PSU doesn't use the maximum wattage. PC hardware generates heat. A power supply with a higher efficiency rating runs cooler dissipating less heat and runs quieter because the fans run slower and/or shorter. Modular PSUs allow the user to plug enough power cables.
80 plus ratings spectrum from better to best are gold, platinum, and titanium. Most users choose gold.
Intel Central Processor Unit (CPU). 1151 socket is 9th generation. 1150 socket is 8th generation. i5 good for gaming. i7 good for creative media. H for gamers and power users. G for light gaming and photo editing. U for everyday use. Y for laptops. K for overclocking. Clock speed more important than the number of cores. The first numbers are the generation number. The second, third, and fourth are the model number indicating number of cores and clock speed. For example, Intel i5-9600k is a 9th generation 600 model overclocking.
Cache is used to speed up access to data and instructions between your CPU and RAM. Cache is information stored to complete repetitive tasks. Cache size is low priority. Most cache sizes are between 1MB-4MB. L1 is the fastest and cramped. L3 is the slowest and spacious. CPU must pair with the motherboard's chipset and CPU sockets.
Side note: I didn't research AMD chips. However, Intel is better for gaming and internet browsing. AMD is better for video editing and photo editing.
Motherboard (MB). A motherboard is a printed circuit board (PCB) that creates a backbone allowing connected components to communicate. Choose a CPU before choosing a motherboard. The socket number is the number of pins in the socket. A processor socket is the mechanism through which a CPU is firmly attached to a motherboard. A chipset is the motherboard software and hardware to allow all the components to communicate or work together.
Z390 for 8th generation and 9th generation Intel chips. Z370 for 8th generation Intel chips. LGA 1151 (300 series) for 9th generation Intel chips. LGA 1150 (300 series) for 8th generation Intel chips. PCIe 3.0 is the latest slots.
Extended ATX, Standard ATX, Micro-ATX, and Mini-ITX are common motherboard form-factors or sizes from biggest to smallest.
Case. Full tower, mid-tower, and mini-ITX are the major case sizes from big to small. Drive bays house storage devices. Tempered glass is today's style. More money spend gets better quality, better looking, and lighter in weight. Cheaper cases are built with lower-quality materials, less sturdy, thinner panels, and wear down quicker. Acrylic glass scratches easier.
Non-Volatile Memory Express (NVMe) Solid-State Drive (SSD). NVMe are the latest SSD providing increased bandwidth, lower power consumption, and lower latency. NVMe are installed in M.2 connectors. PCIe x4 faster than PCIe x2. Peripheral Component Interconnect Express (PCIe) M.2 can be installed in any M.2 slot. SATA M.2 must be installed in a SATA M.2 slot.

Update On A Past Blog
I remember a blog forgetting my job skills A Concern That Requires My Attention on Jan 20, 2013. Forgetting job skills is an example of use it or lose it. I started taking online classes at Accountemps to relearn and to refresh my job skills in Excel, PowerPoint, Access, and Business Analysis. Wrong choice. Accountemps' online classes stank. I corrected my mistake starting on May 2015 learning Python, JavaScript, and CSS. I also relearn my SQL. I refresh my Excel. The rest is ongoing history. Never stop learning. Practice, practice, and practice indefinitely. Learn by repetition.
