What is Uppercase?

Sometimes, uppercase letters are also referred to as caps or capitals, and frequently abbreviated as UC, which indicate that something is important or relevant to the reader. It's a font with more substantial characters. For example, entering A, B, and C results in uppercase, but typing a, b, and c results in lowercase. To text in uppercase, use the Shift and Caps Lock keys on the keyboard. When referring to a computer keyboard key, the CapsLock key may be referred to as CAPS.

Tip

Having everything you enter in ALL UPPERCASE CHARACTERS is bad manners. Most readers assume you are yelling or find the content difficult to understand when you put something in all caps.

Why is capitalization important?

There are some general conditions where we need capitalization, such are as follows:

Passwords

In order to give an added layer of security, passwords are case-sensitive. If you are generating a password and your caps lock key is activated, you will be unable to enter your account the next day if your caps lock key is removed.

File names, directories, and paths

When working with paths, directories, and file names, many operating systems and pathways are case-sensitive. In Microsoft Windows, for example, there is no case sensitivity. However, when you upload a file to the Internet, the files and directories become case-sensitive. This web page's file name, for example, is "uppercase.htm," and the URL must be put in all lowercase while online. No matter, characters are either in uppercase or lowercase if you were viewing the file locally on a Windows PC.

Measurements

Capitalization is vital when working with computers and other measurements since it helps to distinguish the particular type of measurement. "MB" (short for megabyte) and "Mb" (short for megabit) are two different measurements with different values, for example.

Commands

Command line commands in operating systems like Linux are case-sensitive, thus if you typed "Ls" to list files, you'd get an error since the ls command is all lowercase.

Programming functions

Early programming languages like FORTRAN had to use uppercase keywords and data object names since punch card computers didn't have a Shift key.

Acronyms

Letters are typed in uppercase to assist distinguish them from other words in a sentence. For example, the acronym RAM is written in all capital letters to make it easier to recognize as an abbreviation.

Using the uc function

The uc function converts a variable to uppercase in many scripting and programming languages. The uc and ucfirst functions, for example, can be used in Perl as shown in the example below.

The $instance variable is set to all lowercase in the example above. The third line capitalizes the initial character, resulting in "Hello world," while the fifth line capitalizes the entire string, resulting in "HELLO WORLD."

Difference between capitalize and uppercase

When describing a single letter or the first letter of a word, it is referred to as capitalize. For instance, in this statement, the initial letter is capitalised. When every letter of a word is capitalised, it is referred to as uppercase. The acronym CPU, for example, is capitalized.

When should I capitalize text?

The following is a list of some of the general capitalization rules to remember.

  • The first word of a sentence should always be capitalized.
  • The first letter of a word that is derived from a proper noun or is a proper noun should be capitalized. For case, a trademark, a product, a location, a name, a book, a brand should be capitalised as they all are proper nouns.
  • Unless it is part of a sentence, capitalise the first letter of a quote.
  • Before a person's name, capitalise their title (not their vocation).
  • The words "roads" and "streets" should both be capitalised.

The following is a list of situations in which capitalization should not be utilised.

  • Never use capital letters to emphasise a point. Instead, italicise any text that you want to draw attention to.
  • Unless the acronym is a proper noun, all of the words in the entire form should be written in lowercase.
  • When the word the is used before a proper noun, it should not be capitalised.

Should titles and headings be capitalized?

Title case should be used for titles and headings in formal writing. All other forms of writing should adhere to the style guide's guidelines. For instance, Google Alexa employs sentence case for its headlines and follows the Microsoft Manual of Style.

How do switch between lowercase and uppercase letters?

On a smartphone, tablet, computer, or other computing devices, there are several ways to switch between lowercase and uppercase letters. We will go over each method of changing the case of text in the sections below.

Change lowercase to uppercase on a computer

With the help of pressing the Caps Lock or Shift button while typing, you can change the case of any text. If you need to alter the case of text that has already been entered, go to the convert the case step.

  • Capitalize every word you type: Because the Caps Lock key is a toggle key, everything you enter will be in UPPERCASE until you release it or hit it again. All uppercase letters may be typed using the Caps Lock key. Keep in mind, though, that typing in full caps is considered bad etiquette in many settings.
  • Capitalize one letter at a time: Hold down the left or right Shift key while pressing the letter you want to capitalize to change the capitalization of a single letter at a time. On a computer, the Shift key is the most popular way to make a capital letter.

Changing between lowercase and uppercase on a smartphone or tablet

There is no Shift key or Caps Lock available on the tablets or cellphones. On these devices, to capitalise a letter, tap the up arrow on the on-screen keyboard followed by the letter you wish to capitalise.

Should I use "upper case" or "uppercase" in my writing?

Both "upper case" or "uppercase" are acceptable alternatives. In your work, however, just utilize one form. According to The Associated Press Stylebook and the Microsoft Manual of Style, "uppercase" should be written as a single word whether used as an adjective or a noun.
