Important features of system software
Computer manufacturers usually develop system software as an integral part of the computer. The primary responsibility of these software is to create an interface between the computer hardware they create and the end user.
System software usually includes the following features:
- high speed. software must be as efficient as possible to provide an effective platform for higher-level software in a computer system.
Difficult to manipulate. It often requires the use of a programming language, which is more difficult than a more intuitive user interface (UI).
Written in a low-level computer language.
- System software must be written in a computer language that the central processing unit (CPU) and other computer hardware can read.
is close to the system. It connects directly to the hardware that enables the computer to run.
System software has no direct connection to the specific hardware it runs on, and higher-level application software is typically hardware-agnostic and has no direct connection to the hardware it runs on. System software must also support other programs that depend on it as they evolve and change.
Types of system software
System software manages the basic functions of a computer, including disk operating systems, file management utility software, and operating systems.
Other examples of software include:
- BIOS (Basic Input/Output System) initializes the computer system after it is turned on and manages data flow between the OS and attached devices, such as hard drives, video adapters, keyboards, mice, and printers.
- The boot program loads the OS into the computer’s main memory or random access memory (RAM).
An assembler takes the computer’s basic instructions and converts them into a pattern of bits that the computer’s processor can use to perform its basic operations.
- A device driver controls a specific type of device connected to your computer, such as a keyboard or mouse. A driver program converts the OS’s more general I/O instructions into messages that the device type can understand.
In addition, system software may include system utilities, such as disk defragmenters and system restore, and development tools, such as compilers and debuggers.
A computer’s OS is a well-known example of system software. The widely used operating systems include Microsoft Windows, macOS and Linux. Unlike other types of software, the average computer user regularly interacts with the computer OS through its graphical user interface (GUI) and, with some operating systems, through the less complex command-line interface (CLI).
Because a GUI is a program that sits on top of the OS, it is referred to as application software, not software. In other words, a GUI is an application software that makes it possible for the user to manipulate parts of the OS.
Important tasks performed by the operating system
The main responsibility of the operating system is to manage the computer’s software and hardware resources. It is the main control program of the computer. The OS controls and maintains records of all other programs on the computer, including both applications and system software. The OS creates the environment within which all other computer programs run and provides services to other applications.
Operating systems perform functions. Five of the most important are as follows.
- File management and process scheduling. The OS allocates resources and prioritizes which programs should receive resources and in what order. For example, a digital audio workstation application may require a certain level of processing power when used. The OS determines how much power an application gets from the CPU and manages the effects of that allocation on other applications. If a more complex process is taking place elsewhere on the computer, the OS may sacrifice some of the power requested by the digital audio workstation, for example, to ensure that another process can complete.
- Processor and memory management. The OS allocates the computer’s memory for a process when needed and deals with it when the process is complete.
- Error detection. The OS detects, tracks, and debugs errors in the computer’s other programs.
- Security. The OS uses passwords to protect computer programs and data from unauthorized access.
- Control and management. An OS uses compilers, assemblers, and interpreters to control and manage other programs on the computer. These language processors are pieces of system software that translate high-level languages—Java, Python, and C++—that many computer programs write into low-level machine code instructions, which are essentially a series of 1s and 0s. which can be read by the CPU of the computer.
Difference between system software and application software
System software and application programs are two main types of computer software. Unlike software, application software — often referred to simply as applications or applications — performs specific tasks for the end user. Some examples of application software include:
- Web browsers
- Email clients
- Word processors
Application software and system software are coded differently. software is written in system programming languages – such as Executive Systems Problem Oriented Language (ESPOL) — designed to provide easy access to the underlying computer hardware. Application programs are written in general-purpose languages, such as Pascal, which enable programs to use the same code on different platforms. Some languages like C are used for both system and application software.
System software and application software are also triggered differently. software is usually triggered when the computer or device is turned on, and continues until the device is turned off. Application software is triggered by the end user after the computer is turned on. Application software requires software to function, while software can run independently of application software.
In most cases, end users do not interact with the software as it runs in the background. In contrast, end users interact with application software — installing it, booting it, using it to perform specific tasks, booting it, and uninstalling it.
