What is a computer file?
Computer file is a specific data that adheres to the computer system. This data contained can be anything from the executable program to the document created by the user. The computer file consists of a name that creates a file identity and an extension that communicates to the operating system and associated programs what type of file is. The sets have a set of beginning and end, which means they interact with a computer system predictable.
The most common files consist of name and extension. Originally, the file name was limited to eight characters, but modern systems allow much longer file names. The name is generally determined by a user or associated program and often provides the purpose of the files.
File extension is usually a period followed by two to four characters. This part of the file name is used by the operating system for internal cataloging. The way in which extensions are used differ between operating systems; Some require expansion and some ignore it completely. MostIna systems fall among - extensions help identify programs used with the file and act as an abbreviation while reading.
data in the computer file is complete and whole. Information in the file can be opened and read, due to the correct software. The information contained in the file may require additional information to be operated, such as a executable file that needs to correctly make a database file, but executable and database files are two separate files.
Since each computer file is different for itself, there are certain features that are common between any type of file. Each file is size, even if this size is zero. The information stored in the file requires location in the computer system, so each file is indexed by the system. Finally, each file contains attributes that determine its use. These attributes, somewhat can open or change SOUBor or whether the file can be seen by normal users, they are built into the file structure, not its internal data.
The last aspect of each computer file is that they exist in a computer system in some way. A computer file can be created or deleted, moved or copied or changed. The user can do this using programs associated with these files or managing the files of the operating system itself. These operations can be difficult with some files due to their interaction with the operating system, but it can still be done.
