Why do we need a format for binary executable files
When binary files (i.e. executables) are saved they usually have a format (e.g. ELF or .out) where we have a header containing pointers to where data or code is stored inside the file. But why don’t we store the binary files directly in the form of sequence of machine instructions.
Why do we need to store data separately from the code?
Secondly when the assembler creates a binary file is the file is among the above formats?
Way for java program to read file from when it was stopped
I am working on an application that reads a log file, looks for a specific string, sends alert emails and saves data from the file into a database. The reading functionality is working well, but I am coming across an issue when I stop and restart my program. Basically, it always starts from the beginning of the log file, so I am rereading information I have already read. Please reference the example below.

Should log/data files be stored in the database? [duplicate]
This question already has an answer here: Log to file or to database table? (1 answer) Closed 9 years ago. I’m working on a project where we produce lots of data in the form of simple .txt files. These usually contain a set of columns that will later be loaded in to Matlab to be […]

Do bare computer systems (without OS installed) use (executable) files? [duplicate]
This question already has answers here: How do operating systems… run… without having an OS to run in? (12 answers) Closed 8 years ago. As far as I read, files are introduced in OS books. Before an OS is installed on a bare computer system, does the computer use files? In particular, executable files have […]
