There are many mnemonics for the seven layers of the OSI Model in computing. Physical / Data Link / Network / Transport / Session / Presentation / Application

Order of operations[edit]

PEMDAS- Parenthesis, Exponents, Multiplication & Division, Addition & Subtraction can be remembered by the phrase: "Please excuse my dear Aunt Sally"

BEDMAS - Brackets (parenthesis), Exponents, Division & Multiplication, Addition & Subtraction


Remembering the definitions of sine, cosine, and tangent can be done by memorizing SOHCAHTOA, which helps to remind you that Sine = Opposite over Hypotenuse, Cosine = Adjacent over Hypotenuse, and Tangent = Opposite over Adjacent.

Other ways to remember SOHCAHTOA are:

  • Oranges Have Segments, Apples Have Cores, and Oats.
  • Apples Have Cores, Oranges Have Segments, Oranges Are Tangy.
  • Apples Have Cores, Oranges Have Segments, Also Tangy.
  • Some Old Horse Came A-Hoppin' Through Our Alley
  • Silly Old Henry Can't Add Hundreds, Tens Or Anything
  • Simple Old 'Herman Carries A Huge Tub Of Apples
  • Silly Old Harry Caught A Herring Trawling Off America

  • Could A Hungry Stupid Ostrich Have Taken Over America.
  • Some People Have Curly Brown Hair Turned Permanently Black
  • Some Old Hippie Caught Another Hippie Tripping On Acid
  • Some Old Horses Can Always Hear Their Owner Approaching

Another technique is to line up the abbreviations slightly differently: SCT,O/H,A/H,O/A, which stands for Sine Cosine Tangent, Opposite/Hypotenuse, Adjacent/Hypotenuse, Opposite/Adjacent. This mnemonic, "SCTOHAHOA", can be committed to memory as "Sally Can Tell, Oscar Has A Hat On Always". Some students use "Hard On" as opposed to "Hat On", finding that sexual and humorous mnemonics are often easier to recall.

Some people have (sine = perpendicular / hypotenuse) curly brown hair (cosine = base / hypotenuse) through proper brushing (tangent = perpendicular / base) is also used for this purpose.

ASTC stands for All Students Take Calculus, which represents the trigonometric functions that are positive in each quadrant, beginning with the top right and continuing counterclockwise: All, sine, cosine, tangent.


  • For remembering the order of taking the derivative of a quotient in calculus, the phrase "lo-di-hi minus hi-di-lo all over lo squared" can be useful, where lo means the bottom, hi means the top, and di means the derivative. So,

 \frac{d}{d} \frac{high}{low} =\frac{ low\cdot high' -hi\cdot low' }{low^2 }

Another phrase that one may use is: "Bottom d Top, Top d bottom", where "d" stands for derivative (note that this mnemonic does not include the crucial dividing by the bottom squared). Another phrase memorable for sounding like calling a square dance is "Low d high less high d low, Draw the line and square below." So:

 \frac{d}{d} \frac{high}{low} =\frac{ low\cdot high' -hi\cdot low' ; Draw the line and }{Square below}

Pi (π)[edit]

Characteristic sequence of letters[edit]

  • I always comes before E (but after C, E comes before I)[26][27]

In most words like friend, field, piece,pierce, mischief, thief, tier, it is "i" which comes before "e". But on some words with c just before the pair of e and i, like receive, perceive, "e" comes before "i". This can be remembered by the following mnemonic,

I before E, except after C

But this is not always obeyed as in case of weird and weigh,weight,height,neighbor etc. and can be remembered by extending that mnemonic as given below

I before E, except after C
Or when sounded "A" as in neighbor, weigh and weight
Or when sounded like "eye" as in height
And "weird" is just weird

Another variant, which avoids confusion when the two letters represent different sounds instead of a single sound, as in atheist or being, runs

When it says ee
Put i before e
But not after c
  • Where ever there is a Q there is a U too

Most frequently u follows q. e.g.: Que, queen, question, quack, quark, quartz, quarry, quit, Pique, torque, macaque, exchequer. Hence the mnemonic:

Where ever there is a Q there is a U too[27](But this is violated by some words; see:List of English words containing Q not followed by U)
  • When two vowels go walking the first does the talking[23]

For words like "oat" or "eat", here the second letter a is silent and first letter o and e respectively are pronounced in the examples

Letters of specific syllables in a word[edit]

There was a farmer named Sep and one day his wife saw a rat. She yelled, “Sep! A rat – E!!!”[29]

Distinguishing between similar words[edit]

  • Difference between Advice & Advise, Practice & Practise, Licence & License etc.

Advice, Practice, Licence etc. (those with c) are nouns and Advise, Practise, License etc. are verbs.

One way of remembering this is that the word ‘noun’ comes before the word ‘verb’ in the dictionary; likewise ‘c’ comes before ‘s’, so the nouns are ‘practice,licence,advice’ and the verbs are ‘practise,license,advise’.[30]
  • Here or Hear
We hear with our ear.
  • Complement and Compliment
complement adds something to make it enough
compliment puts you in the limelight[27]
  • Principle and Principal
Your principal is your pal
A rule can be called a principle[29]
  • Sculpture and Sculptor
A sculpture is a kind of picture[29]
  • Stationary and stationery
