In electrical transmission lines, the term loading means the insertion of impedance into a circuit to change the characteristics of the circuit.

The loading of a communication channel may be expressed as (a) the equivalent mean power and the peak power as a function of the number of voice channels or (b) the equivalent power of a multichannel complex or signal composite referred to zero transmission level point (0TLP).

Chemically, loading is the process by which insoluble small suspended particles are made heavier by adding alum in order to increase the rate of sedimentation of particles.

Computers and electronic devices take time to save or open files, which is commonly tracked with a 'loading bar, or progress bar as it is officially named. They show progress with visual representation, i.e. filling a box, and may include amount processed or percentage processed. These bars help the user understand how much time they have to wait. Most have the word "Loading..." somewhere on the bar, hence the term "Loading bar".

In computing, a newline, also known as a line break or end-of-line (EOL) marker, is a special character or sequence of characters signifying the end of a line of text. The name comes from the fact that the next character after the newline will appear on a new line—that is, on the next line below the text immediately preceding the newline. The actual codes representing a newline vary across operating systems, which can be a problem when exchanging text files between systems with different newline representations.

There is also some confusion whether newlines terminate or separate lines. If a newline is considered a separator, there will be no newline after the last line of a file. The general convention on most systems is to add a newline even after the last line, i.e. to treat newline as a line terminator. Some programs have problems processing the last line of a file if it is not newline terminated. Conversely, programs that expect newline to be used as a separator will interpret a final newline as starting a new (empty) line.
