There are various categories of system software, and all are developed for controlling and coordinating the procedure of system hardware. They enable the interaction between the users and hardware system, software system. Software system generally employs a third person to make sure that communication between different software system and hardware system for offering the harmonious existence with respect to the users. Mainly the system software can be categorized in the following ways:
- Operating System (OS Software)
It provides the communication between the system of hardware and software and another program. It is a kind of computer software which places the bridge between the computer hardware and end users. It is downloaded in the system for permitting the devices and recognized programs to be functional performance. It is the first layer among the system software which is to be loaded into the memory storage of the system.
Assume that you desire for writing and printing the report card to the connected printing machine. Usually, the application designed for the word processing is needed to attaining the task. You can use the keyboard for data input and then you will find the output in the screen of the monitor. The prepared data is now delivered to the printing machine. For attaining the tasks, devices like keyboard and printing machine must perform their working with the operating system. This is the OS which coordinates the functionality of input and output devices including the memory storage management and many more.
You can interact with the OS via GUI (Graphical User Interface) on the monitor or the interface provided by the touch screen. In case of the modern operating system, the desktop is the graphical workspace as it comprises of the menus, app icons, and software programs. These are calibrated with the users via the cursor or the touching fingers. There are many examples of OS like Windows 10, Mac OS X etc.
- Device Drivers Software
Drivers of the device are also considered in the list of computer software. This is responsible for having the computer devices and other accessories in life. Drivers help to work the specific tasks, as commanded by the operating system, of all linked devices including the external add-ons. Device drivers play an important role in the communication of device with the operating system and other applications.
It is true that the drivers of accessories for the data input are downloaded with the system by default. In this case, it doesn’t need for the third party. When the device is more recent than the OS, then the users can install the driver’s software from the site of the manufacturing sources.
- Firmware System Software
It is a type of the operational program enveloped with the flash chip, ROM (read only memory) or other memory slots for the operating system to recognize it. Firmware maintains and controls the entire events and tasks of each hardware system. Conventionally, it was downloaded on the non-volatile memory chips, and it can be having its upgraded version with the exchanging them by the new memory chip. Nowadays, this operational software is collected on the flash chips that can be having its higher version without the replacing the chips. Firmware is upgraded through the manufacturing source of the device and not of the operating system.
- Programming Language Translating software
It is counted in the intermediate-level software but depended on the programmers for translating the high-level programming language into the code language of the machine. The high-level language is easy to our minds for making the code on it and comprehending, but it Is not the case with machine coding language.
Only the processors can identify the Machine coding. The famous programs for translating the language include the assemblers, compilers and tools of interpreters. Generally, this tool has been developed by the only system manufacturing sources. The translation process can be performed in a different way such as translating the entire codes of the program or translating as per the command at that time.
