What is Programming Language Resource Management?
Programming language resource management refers to the act of managing all of the resources that are necessary for the proper functioning of a computer program. Also, resources that are managed may include memory, CPU time, and I/O (input/output) devices.
The primary purpose of programming language resource management is to ensure that the program runs. It is with minimum resources and optimal performance.
Programming resource management is generally done by a system resource manager. This is different from operating system resource management, which controls the sharing of the computer memory, CPU (central processing unit) time, and I/O resources among multiple tasks.
A computer program may need to use several resources at the same time. Certain resources may be available only for limited periods. Some programs may run concurrently with other programs, and hence they need to share resources such as memory and CPU time.
In a situation like this, the system resource manager can be relatively complex. It needs to check whether the resources are available and if so, allocate them to the requesting program. Also, it needs to keep track of the usage of these resources and make sure that they are after use.
Programming resource management can be a complicated affair at times. Also, it requires a lot of effort and skill on part of the programmer, and even an experienced programmer may make mistakes. This is because programming language resource management requires several processes to be in a specific sequence.
The process of programming resource management may vary from one programming language to another, owing to the differences between them.
Allocation and Deallocation of Memory space
Allocation and deallocation of memory space is an important process in programming resource management. The resource manager allocates a block of memory space to the requesting program.
It also deallocates this block when the program is ended. For instance, the C programming language uses malloc() and free() functions for this purpose.
Allocation of CPU time is a very important process in programming language resource management. The requesting program may want to keep the CPU busy while carrying out its task.
Therefore, it needs to be a certain amount of CPU time. However, if the requesting program does not require CPU time, then it should be immediate.
The primary advantage of programming resource management is that it makes the program run with optimum performance. However, it is important to note that this happens only if the resource manager works correctly.
Also, programming resource management is important because, in case of an error, it can help a programmer figure out what went wrong. This is because the code will have a lot of references to the functions used by the resource manager. Also, the resource manager may have a lot of references to the code which is being executed.
The main disadvantage of programming resource management is that it increases complexity in the code. This is because the resource manager has a lot of functions to manage memory, CPU time, and I/O devices. Also, a section of code that uses these functions will have a lot of complex code.
Programming language resource management can be very complex at times. Also, it may increase the complexity of the program being executed.
