PAO stands for Process-Architecture-Optimization, a new acronym Intel coined when they changed processor development strategies in 2016 from their former Tick-Tock strategy which had been use since as far back as 2007.

Whereas the Tick-Tock strategy shrunk the node for every “tick” and the architecture was redesigned for every “tock”, the new PAO strategy for Intel shrinks the node for the process stage, redesigns the architecture in the architecture stage, and optimizes both the process and the architecture in the optimization stage. Whereas in Tick-Tock it meant just two processor generations for each design node, PAO means there will be three processor generation for every design node.


Price/GB is a simple ratio for measuring the price of any storage device. It’s calculated by dividing the cost of the drive by its capacity. The lower the number, the better.


An PSU, or Power Supply Unit, is a hardware component that supplies power to an electronic device such as a computer. PSUs are typically used to convert AC, or Alternating Current, from the electric company to DC, or Direct Current, which is the type of electricity used in most electronic devices.

PSUs are typically categorized into two types: external and internal. Internal PSUs are those found in desktop computers, monitors, TVs, etc where the power supply is integrated into the electronic device and only a power cord is needed to connect to the wall socket.

External PSUs are those found in laptops or other devices where the PSU is sitting somewhere between the electronic component and the wall outlet. Oftentimes, these are also referred to as power adapters or power bricks.


PuTTY is a free and open source terminal emulator application developed by Simon Tatham. It’s the most popular terminal emulator on the internet supporting protocols such as SSH, Telnet, SCP, SFTP, serial, rlogin, and raw socket. Given its open source nature, there are forked versions of PuTTY that provide additional features and functionality.

The most common usage of PuTTY is for terminal emulation using the SSH or Telnet protocols. These protocols allow remote terminal access for administration of servers or devices running SSH or Telnet servers.
