JPEG is an image format that supports high compression.

BMP is the abbreviation of bitmap, which is a bitmap picture. Bitmap pictures store image information in units called pixels. These "pixels" are actually some neatly arranged colored (or black and white) dots. If you enlarge these points slowly, you will see that the "pixels" are filled with their own colors.

Complete set of file suffixes (required for beginners)

What is the file name suffix? Speaking of the file name under the Windows work interface, it is simply arbitrary, such as the work plan of an editorial department in 2000. The file name can be directly expressed in Chinese, with a maximum length of 256 characters, which makes people look really clear at a glance. However, in the Windows environment, there are many file names like CALENDAR.EXE and Game. GRP etc. are in the installed software. Why? It turns out that these file names are based on the naming rules of file names in DOS environment. The file name in DOS environment adopts 8+3 structure, that is, the longest 8 digits in the file name are separated by decimal point and then added with the longest 3-digit suffix, such as READ. Me and SETUP.EXE. Chinese characters are generally not allowed in the file name, which can only be composed of letters, numbers and some symbols. For example, reading. ME is understood as "read me" in Chinese, which means to prompt users to read the contents of this file before using the software to get more prompt information. More importantly, DOS stipulates the use of suffixes to distinguish different files. Executable files are the most easily encountered under DOS, and there are two suffixes: *. Exe and *. Com (where * stands for any file name) is a program written in assembly language or other high-level languages and a file that runs directly under DOS. Sometimes, due to many software functions and small memory, it is impossible to transfer all of them into memory at one time. There may be an ovl file with the same name, such as ws.exe, ws.ovl, and another file can be directly run. Bat, a batch file, contains the names of many commands or executable files, which are mainly used to improve work efficiency. The most useful file is Autoexec.bat, which will be automatically executed after opening (automatic execution is English automatic execution). Another file that can be loaded but not directly run is the system extension management file *. Sys (system) mainly provides drivers for some nonstandard devices such as mouse, extended memory, etc. For unified management, a text file of config.sys is specially designated, and these necessary device drivers are automatically loaded at startup. Once these files are deleted or renamed by mistake or attacked by viruses, the system will work abnormally directly. Files generated by word processing in DOS can be generated without suffix, but people often use *. Txt to represent it (txt is text). Supported by all platforms and all applications. For the convenience of management, people can also use their own names as suffixes to indicate that they have created their own text files. For example, many articles I input are *.mcj. In order to facilitate users to restore the original files as soon as possible in the case of deleting the original files by mistake, many word processing systems provide automatic backup functions. For example, when I edited Ji Hua. The second MCJ (Plan Hanyu Pinyin), the system will first copy an original file as a plan. When using word processing software with special format functions, such as WPS introduced by Mr. Qiu Bojun in his early years, its suffix will be designated as. WPS to identify the text file generated by wps. When editing high-level language programs with word processing software, the suffix is usually the first three letters of the corresponding language (for example, *). BAS is the source program of BASIC language. PAS is a PASCAL language program. FOR is a Fortran language program. C is a C language program, and *. ASM is an assembly language program). The following types of files are usually attached to executable files: *. HLP is a help file. CFG is the configuration file. DAT is a data file. LOG is a log file, and *. TMP is a temporary file.
