Tech, decoded

What does "bandwidth" mean? Tech terms finally explained

Picture this: you're at dinner with family, and someone says, "Oh, it's slow because of the bandwidth—you should really set up 2FA on that account." Everyone nods. You nod too, mostly to avoid follow-up questions. Sound familiar? Here's the thing: this stuff is actually useful in today's modern life, and you do not need to be a tech expert to get it. Stick with us through these explanations, and you'll walk away with the kind of knowledge that comes in handy more often than you'd think.

Think of bandwidth like a highway. A two-lane road can only handle so many cars at once—but a twelve-lane highway? Traffic flows freely. Bandwidth works the same way: the higher your bandwidth, the more data your internet connection can handle at the same time, and the faster everything feels. It's why streaming a movie, video-calling the grandkids, and checking email all at once can slow things down.

The average American household now uses about 500 GB of data per month: roughly equal to streaming 166 full-length movies.

Encryption is the process of scrambling data into a secret code that only the intended recipient can decode. Think of it like sending a letter written in a language only you and the receiver know; even if someone intercepts it, it's gibberish to them.

Every time you shop online or log into your bank, encryption is working quietly in the background to protect your information. Military-grade encryption used for online banking would take a regular computer longer than the age of the universe to crack by brute force.

A cache is like your browser's memory for things it's seen before: When you visit a website, your device quietly saves pieces of it—images, buttons, layout—so the next time you go back, it doesn't have to download everything again from scratch. It's the digital equivalent of leaving your reading glasses on the nightstand instead of searching the whole house every morning.

If a website looks funny or outdated, someone might tell you to "clear your cache." That just means wiping that saved memory so your browser fetches a fresh version.

Latency is the tiny gap between when you do something, like saying a word on a video call, and when the other side hears it. Low latency means things feel instant and snappy. High latency means you're talking over someone on Zoom, and it takes a couple of seconds for the other person to hear it.

The human brain detects audio delay at around 20 milliseconds: about the same time it takes to blink.

An API—Application Programming Interface—sounds terrifying, but the concept is simple. Imagine you're at a restaurant. You don't go into the kitchen and cook your food; you tell the waiter what you want, and the waiter brings it back. An API does the same thing between software programs: it carries requests from one app to another and brings back the answer.

Your weather app doesn't collect its own weather data; it asks a weather service through an API.

"The cloud" sounds mysterious, but it's really just someone else's computer: a very big, very powerful one in a data center somewhere. When you save a photo to iCloud or open a Google Doc, that file isn't sitting on your device. It's stored on a server far away, and your internet connection is the bridge that lets you reach it.

The practical benefit? If you drop your phone in a lake, your photos are still safe. Fun fact: The world's cloud data centers use more electricity than the entire United Kingdom—every single day.

Phishing is when a bad actor sends you an email, text, or fake website pretending to be someone you trust, like your bank, Amazon, or the IRS, to trick you into handing over your password or credit card number. It's the digital version of a con man in a suit showing up at your door claiming to be from the gas company. The disguise looks real; the intentions are not.

If something feels off—a weird sender address, urgent scary language, a link that doesn't quite match—trust your gut and don't click.

Malware is short for "malicious software": basically, any program that sneaks onto your device to cause trouble. Some malware spies on what you type. Some lock your files and demand money to release them.

However, a reputable antivirus program and a healthy dose of caution go a long way. Don't click suspicious links. Don't plug in a random USB drive you found. Don't install software from websites you've never heard of.

An algorithm is just a set of instructions that a computer follows to make decisions or solve problems. When Facebook shows you certain posts first, or YouTube suggests a video, an algorithm made that choice. It's studying what you click, what you pause on, what you like, and using all of that to serve up more of the same. It's worth knowing this because it means your feed is a reflection of your behavior.

Want different results? Change your habits: like, comment, or search for different things, and the algorithm quietly shifts.

Two-factor authentication is like having a deadbolt in addition to your regular door lock. Even if someone gets your password, they still can't get in without a second piece of proof, usually a code sent to your phone.

Most apps make it very easy to set up, and the inconvenience is minimal compared to what it protects. Microsoft reports that accounts with 2FA enabled are over 99% less likely to be compromised.

A VPN—Virtual Private Network—is like a secret tunnel your internet traffic travels through instead of the open road. When you use one, your data is encrypted and routed through a server somewhere else, hiding your real location and making it much harder for anyone to snoop on what you're doing online.

VPNs are especially useful on public Wi-Fi, like at the airport or a coffee shop, where your connection could otherwise be visible to strangers on the same network. It's not magic, it just makes your device look like it's somewhere it isn't.

A software update is a new, improved version of a program or operating system. Updates don't just add new features; they often patch security holes that hackers have already discovered and are actively trying to exploit. Ignoring them is a bit like knowing your back door lock is broken and deciding you'll fix it next weekend.

Updating your phone or computer software takes a few minutes, and it's one of the simplest things you can do to protect yourself online.

Linguistic innovation

Shakespeare said it first: 10 words coined by the Bard

Rumor has it that William Shakespeare coined over 1,700 new English words or, at least, he was the first to put them in writing. If you have ever heard this fact, it might make you think of sophisticated-sounding terms like sanctimonious, equivocal, or radiance, all invented by the Bard. But many of the words we use in everyday life have Shakespearean origins, no matter how mundane they might seem. Let’s explore Shakespeare’s mark on our daily vocabulary.

First recorded in: A Midsummer Night's Dream

When Shakespeare first used the word ‘bedroom’ (around the 1580s), the common way of referring to a space intended for sleeping was ‘chamber’ or ‘bedchamber’. Why did the bard choose a different word then? He was not referring to what we now understand as a bedroom. In Act 2, Scene 2 of A Midsummer Night's Dream, when Lysander asks Hermia for "bed-room", he is asking to lie next to her in the bed. The change from ‘space in the bed’ to ‘a room intended for sleeping’ occurred a few decades later, and the current use of 'bedroom' was set around the 1610s.

First recorded in: A Midsummer Night's Dream

We commonly use this word to describe the behavior or attitude of someone very confident and bold, and its first recorded use was not that different, though it bore a negative connotation. In Act 3, Scene 1 of A Midsummer Night's Dream, Puck uses the word "swaggering" to mockingly describe the rustic manners of the actors rehearsing a play. A few years later, Shakespeare used "swaggerer" in Act 2, Scene 4 of Henry IV, Part 2, to describe the noisy, boastful, and brawling Pistol. Nowadays, ‘swagger’ is most of the time used with a positive connotation.

First recorded in: Coriolanus

If Shakespeare ever heard Kelly Clarkson singing "doesn't mean I'm lonely when I'm alone," he would think the verse redundant, because he coined the word ‘lonely’ to mean ‘alone’. In Coriolanus (Act 4, Scene 1), the titular character says "I go alone, like to a lonely dragon, that his fen makes fear'd and talk'd of more than seen". While Coriolanus used the word to compare himself with a solitary or isolated creature, ‘lonely’ evolved to mean ‘sad for lack of company’ in the early 19th century.

First recorded in: Macbeth

While linguists believe that ‘assassine’ was already in use in the 1570s, ‘assassination’ was first recorded in print around 1605 in Shakespeare’s Macbeth. A word of Arabic origin (from hassassin, ‘hashish-user’) that pejoratively described a group of mercenary killers, it had entered English through the Italian assassino. In Macbeth (Act 1, scene 7), the main character, while contemplating killing the king, refers to the potential murder as an ‘assassination’.

First recorded in: Troilus and Cressida

While in modern times we understand fashionable as ‘following the latest trends’, Shakespeare’s use was slightly different. In Act 3, scene 3 of Troilus and Cressida, the character Ulysses describes time as "a fashionable host", using the term to mean ‘popular’. While its meaning has changed slightly since then, the association with something popular remains.

First recorded in: Venus and Adonis

Was Shakespeare the first to record this word? Yes and no. In 1575, a scholar named William Patten had recorded the term ‘eye ball’, but Shakespeare was the first to use it as a single word in the 1593 poem Venus and Adonis, "Look in mine eyeballs, there thy beauty lies". How did people refer to the eyeball before that? They simply called it the ‘eye’.

First recorded in: Julius Caesar

Historians are certain about this one: the word ‘generous’ was not coined by Shakespeare, but he was responsible for making it popular and cementing its meaning as ‘freely giving’. From the Latin generosus (‘of noble birth’, ‘honorable’), the term had entered English through French with that original meaning. Shakespeare had used it as ‘honorable’ or ‘high ranking’ in Love's Labour's Lost (c. 1594), but he later used it in 1599's Julius Caesar (Act 2, scene 3) to describe the unselfishness and altruism of Caesar, who had made provisions for every Roman citizen in his will.

First recorded in: The Taming of the Shrew

Before Shakespeare’s time, English people certainly undressed, but they used words like unclothe, strip, or the Old English unscrydan to describe the action. The French dresser (´to arrange’, ‘put in order’) entered English in the 14th century, and shifted from general to personal order in the following century, eventually being used solely for clothes. Shakespeare’s The Taming of the Shrew (c. 1590) contains the first written record of the opposite verb, ‘to undress’, in its prologue: "Madam, undress you, and come now to bed."

First recorded in: Titus Andronicus

Although ‘vary’ (from the Latin variare, ‘to change or make different’) was already in use during the 1500s, Shakespeare is widely considered the first to record its adjectival form with the meaning ‘something that contains many different things’. In 1591’s Titus Andronicus (Act 3, scene 1), the character Marcus compares the voice of his now-mute niece Lavinia with a bird that sang "sweet varied notes".

First recorded in: Love’s Labour’s Lost

The Greek kritikos, meaning ‘able to judge’, was already used in English before Shakespeare’s time, but it referred to skilled judges or literary correctors. In Act 3, scene 1, of Love’s Labour’s Lost, Berowne, initially cynical about love but having fallen for Rosalind, describes his former self as "A critic, nay, a nightwatch constable", making this the first recorded use of the word to mean someone who points out flaws or looks upon others with contempt.
