"text" and "binary"
Explain the various file-accessing techniques in data management system. Also state the advantages and limitations of each technique
Two file modes are "text" and "binary". Text is used for human readable data, such as a C source file, or a notepad text file. Binary is used for computer readable data, such as an executable object file. Two other file modes are "sequential" and "random". Sequential is used when the file is accessed serially, from the beginning to the end, and can be used for both text and binary files. Random is used when the file is accessed non-serially, often jumping around from place to place. An example of random is a database file.
In computer programming, a file descriptor (FD) is an abstract indicator for accessing a file. The term is generally used in POSIX operating systems.
The file(s) (data) which are accessed in a sequential or a orderly manner is called as a sequentially accessing a file.
They store records in the order they are enterwd and accessing or processing.
FTP (File Transfer Protocal) supports both ASCII & Binary.
Some limitation of file processing include:1. Data redundancy and inconsistency2. Difficulty in accessing data3. challenges with data security4. Often, time consuming and tedious
Identify the location or path of the file you want to access on your device. Use a file manager or file explorer software to navigate to the file's location. Open the file using an appropriate application or software that is compatible with the file format.
Accessing a user's file when requested by the user's coworker
It provides a convenient way of accessing a shared resource such as a folder, file or printer.
Depends on the followings:The file storage locationThe operating system of the program/software tries to open the fileWhat the computer language was written in of that software to open the fileSome languages may supply different ways to open a file in their library code, some may not supply any.For those do, usually, the modes are:Read only (implies the file must exist, sequential or random access)Write (file may not exist, may be sequentially or random access)Append (file may not exist, write to the end of file)
I guess you mean either input/output/inout/append or binary/text.
