U 16 Storage, compression and file size

Storage

Flash Drive - A USB flash drive consists of a flash memory data storage device integrated with a USB interface. USB Flash Drives are typically removable and rewritable. It can be attached to a keychain. When you plug a USB Flash Drive into your computer USB port, the computer recognises it as a mass storage device and assigns it a drive letter.

Hard drive – A hard drive is a piece of hardware used to store digital content and data on computers. Every computer has an internal hard drive, but you can also get external hard drives that can be used to expand the storage of a computer.

SSD – An SSD (Solid-State Drive) is a newer and advanced form of a hard drive that works as a storage device in computers. With no moving parts, SSDs access and deliver data more quickly than traditional drives.

Cloud – Cloud computing means storing and accessing data and programs over the internet instead of your computer’s hard drive. (The PCMAG Encyclopaedia defines it succinctly as “hardware and software services from a prover on the internet.”) Ultimately, the “cloud” is just a metaphor for the internet.

Compression

DRC – A new (dynamic rang compression) DRC tag can now used to tag and enhance the volume of a certain sounds in your audio file. The sounds in an audio file range from softer sounds to louder, depending on the text, the language and the voice.

Downwards/Upwards – Downwards compression treats the signal only when it goes above the threshold, by reducing the volume or “pushing it down” On the other hand, upwards compression only affects audio signals below the threshold, by increasing the volume and pushing everything up.

Size VS Quality

Lossy – Lossy compression means that the image size is reduced while some data from the original image file is eliminated.

Lossless – A lossless file, the FLAC (Free Lossless Audio Codec) is compressed to nearly half the size of an uncompressed WAV or AIFF of equivalent sample rate, but there should be no “loss” in terms of how it sounds. FLAC flies can also provide a resolution of up to 32-bit, 96kHz, so better than CD quality.

Bit rate – Bit rate refers to the amount of audio bits transferred at a given time. It is usually measured in kilobits per second (kbps) The higher the bitrate, the larger the audio file.

Files size – File size is the measurement of space a file takes up on a storage medium, such as a computer hard drive or ad server. Also, the resolution of your image has nothing to do with its file size. However, the file size of the image on the left is 630% larger. This makes a big difference in a page load speed, especially when using larger dimension images and when using multiple images on a page.
