That's a big part of it. jpg is short for JPEG, which is the file format for photos, and realistic paintings. So yes, it's a form of lossy compression in pictures. The more compressed it gets, the worse it looks.
If you are still curious, see: https://en.wikipedia.org/wiki/JPEG#Typical_usage
Lossless compression recreates a compressed file as an identical match to its original form. While lossy compression can't be used to compress anything that needs to be reproduced exactly.
Lossy= Is generally more effective but when opening file it loses some data. This is most noticeable in compressed pictures Lossless= Is the most common method of compression and loses none of the data
Data compression refers to the process of reducing the size of a data file or dataset by encoding its information more efficiently. This can be achieved through various techniques, such as removing redundancy or using algorithms that represent data in a more compact form. The primary goal is to save storage space and decrease transmission time, making it easier to store and share large amounts of data. Compression can be lossless, preserving all original data, or lossy, where some data is sacrificed for greater size reduction.
Data is raw facts and figures that a computer processes by following a set of instructions. Databy itself has no meaning.For example:Data can be in the form of letter or numbers.
Compression.
When molecules of air are pushed together, they form an area of high pressure which is called compression. If the compression is cyclonic, it is called a node.

A series of instructions telling a computer how to read a compressed file is typically referred to as a decompression algorithm. This algorithm processes the compressed data, interpreting its format and reconstructing the original file by reversing the compression process. Common decompression algorithms include ZIP, GZIP, and LZ77, each designed for specific compression techniques. The computer executes these instructions to restore the file to its usable form.

CW in telecommunications refers to the carrier wave. It's not a form of CB lingo or jargon.
