Compression: meaning, definitions and examples

General context where pressure or volume reduction is involved; often used in mechanical or physical settings.

• Compression of the gas in the cylinder makes it easier to ignite
• The compression of the spring stores potential energy

Specific to the process of reducing the size of files, mainly for storage and transfer purposes.

• Using file compression can significantly reduce the size of your attachments in an email
• File compression is necessary to archive large volumes of data

Used specifically in the context of reducing the size of data files to save storage space or transmission time in digital systems.

• Data compression algorithms like ZIP and RAR help to minimize file sizes
• Data compression is essential for efficient data transfer over the internet

Refers to any method or process aimed at decreasing the size of files; may involve compression, but can also include other techniques like removing unnecessary data or formats.

• Consider file size reduction techniques before uploading your project files
• File size reduction can help you store more files on your hard drive

Used in medical or physical therapy contexts to describe the process of applying pressure to reduce swelling, improve blood flow, or support injured tissues.

• The doctor recommended compression socks for better blood circulation
• Post-surgery, compression wraps are often used to manage inflammation

This term is more general and can refer to any method of applying pressure, whether through manual means, bandages, or other medical devices, often to stop bleeding or reduce swelling.

• Immediate pressure application was necessary to stop the bleeding
• Proper pressure application can help in managing bruises

This is often used in reference to specialized clothing designed to provide support and compression for medical, athletic, or cosmetic purposes.

• She wore a support garment after her surgery for better healing
• Athletes often use support garments to prevent muscle strain

Used to provide support or to wrap around an injured area to apply consistent, gentle pressure. Commonly found in first aid kits and used in sports.

• He wrapped an elastic bandage around his sprained ankle
• The nurse secured the wound with an elastic bandage to minimize swelling

Can also mean mental or emotional pressure, though less common.

• The compression of deadlines and expectations weighed heavily on her mind

Best used in medical or procedural contexts where pressure is applied intentionally for a specific purpose, such as stopping a bleed or forming a shape.

• The doctor stopped the bleeding by the careful pressure application on the wound
• Skilled pressure application is essential in making pottery

Used in physical contexts where an emphasis is on the act of applying force, such as in sports or mechanics.

• The athlete's force exertion was evident during the weightlifting competition
• Engine performance is improved through the efficient exertion of force

Primarily used in general and scientific contexts to describe the process of decreasing the amount or space occupied by a substance or object.

• The recycler's job involves volume reduction of waste materials
• Volume reduction in engineering helps in minimizing space and maximizing efficiency
