virtual memory

Last edited: August 8, 2025

We are trying to share a resource: memory; memory allows multiple processes to use a share pool of memory.

key goals

  • multitasking: multiple processes should be able to use memory
  • transparency: no process need to know that memory is shared; each process should be able to run regardless of the number/locations of processes
  • isolation: processes shouldn’t be able to corrupt other processes’ memory
  • efficiency: shouldn’t be degraded by sharing

virtual memory

The operating system will translate virtual addresses (which are 0 based for every program, which isn’t a problem) to physical addresses in memory.

voltage

Last edited: August 8, 2025

voltage is a measure of difference in electric potential energy across two points

\begin{equation} V = \frac{1}{4\pi \epsilon_{0}} \sum_{i} \frac{q_{i}}{r_{i}} \end{equation}

or,

\begin{equation} PE = qV \end{equation}

potential energy experienced by \(q\) at the point.

\begin{equation} E_{x} = -\dv{V}{x} \end{equation}

\begin{equation} \Delta V = - \int E \cdot dr \end{equation}

\begin{equation} PE = \frac{1}{4\pi \epsilon_{0}} \frac{q_1q_2}{r} \end{equation}

equipotentential lines and electric field lines should align at right angles.

  • current through series is the same
  • voltage through parallel is the same

VWAP

Last edited: August 8, 2025

The VWAP is a Financial Market metric that stands for “volume-weighted average price.” It is given by (sumshares brought(shares bought at price*price its at)/(total shares bought in period)).

“the price we care the most about, is the price where the most volume is traded.”

Motivation

Its a weighted-by volume trading price. Though the closing price is the price used for accounting, it isn’t a good metric for large-volume trades.

Trading at the VWAP

We Trade at the VWAP because a LARGE trade will move the market around, and we don’t want that if we are a large trader. So we trade at the VWAP to ensure that we are getting the best possible value.
