DDR4 RAM
Double Data Rate, which is the DDR in DDR4, tells us something about the rate of data transfer in a given type of memory. The first number, as in DDR4, tells us the generation of the memory. DDR3 was the previous generation, DDR4 is the current generation. DDR4 offers faster data transfer rates than its predecessor. The second numeric value as inDDR4-1600- or DDR4-2666 is the speed. Memory type and speed must be matched to the requirements of your computer.
DDR4 has improved function compared with DDR3, in that it offers faster data transfer rates, It has more memory banks giving it increased capacity. It also requires less energy so it is more power efficient. The more capacity and the faster the speed, the better your memory is able to keep up with today's multi-core processors.
DDR form factors designate what they are used for. The DIMM form factor is used in desktop systems while the SO-DIMM form factor is used for laptops and all-in-one computers because of their slim profile.
Solid State Drive
More reliable and significantly faster than traditional spinning-platter hardrives, solid state drives work more like a large flash drive giving you quick access to your data. With no moving parts generating heat, solid state drives use less power and keep your system cooler which helps reduce component failure. Light weight and durable, solid state drives are often found in portable devices since they are less prone to travel damage and accidents like being dropped.

With SpeedStep technology, your processor simultaneously switches voltage and frequency to high or low levels depending on processor load. Enhanced SpeedStep technology performs voltage and frequency changes separately so the system performs better with reduced latency due to system unavailability.
Thermal Monitoring Technologies
This feature is designed to protect the processor in the event of unusual circumstances such as cooling fan failure which can cause damage if internal chassis temperatures become higher than normal. It works by reducing the processor's power consumption if the programmed thermal temperature is exceeded.
The processor contains a thermal diode which measures the actual CPU temperature and relays its temperature and thermal requirements to the motherboard. The motherboard uses those requirements to control the processor fan and ensure it does not spin faster than necessary - even under worst case power use.
Intel IPT Identity Protection Technology
Designed to provide another layer of online security, Intel IPT works by partnering with websites to help keep your personal information safe when you log in to your favorite IPT-enabled sites like shopping, bill paying, banking, etc. Intel IPT verifies your log-in, confirms you're using a trusted device, and protects your account from being accessed without your recognized device.
