System software plays a crucial role in the lifecycle of computer systems, and it helps to interface between hardware and user applications. If we take a look at the layered model of an operating system, we come across the fact that users interact with it almost every time we use our devices. System browsers take care of things like files and folders, and help your computer run smoothly and fast! These types of programs can be used on any given device: phones, tablets or personal computers. It doesn’t matter what underlying system you’re running even if you’re using Mac OSX, this category will cover just about every layer there is when discussing your chosen subject matter.
Important features of System software:
A computer system is most commonly called an operating system or platform. An operating system can either be a software application programming interface (API) for languages like C++, C#, Java, etc., or it can be part of the hardware itself. While there are many differences in operating systems available today, there are also many similarities that arise for the purpose of making them work on different types of hardware.
Types of system Software:
System software works as the key enabler between hardware and other software we may use. It enables it to interact. In order for a computer system to process, transmit, receive and store information from its data bus, power supply systems and other peripheral devices, it requires a system software infrastructure. Both hardware and software have been created by different developments or engineer teams whose responsibilities are then marketed or sold under their own brand names.
Assemblers handle low-level software instructions and convert them into the binary code that the processor can understand. Drivers are special programs that tell your computer how to communicate with each piece of hardware attached to it, be it your mouse or keyboard. System utilities let you do things like defragment hard drives to free up space, run diagnostics on your computer system, or even pause execution of a program so you can troubleshoot any errors arise without having to restart anything.
The OS of a computer is an example of system software. Technologies are considered system software when they are essential to the functioning of large pieces of hardware or devices, such as computers or routers. System software also includes operating systems, firmware, device drivers and more. Software is considered application software when it runs on top of system software. The user interacts with application software through the device’s graphical user interface (GUI) or command-line interface (CLI).
Important Tasks Performed By The Operating System
The main responsibility of any operating system is to manage a computer’s software and hardware resources. It is the computer’s main control program with most models running on its core processor with most models providing the fundamental means of organizing and making available computing resources such as processing power, peripherals, memory, networking connectivity and storage devices to all other programs whether they be application software or systems software for use by other applications. Operating systems perform tasks, five of which are:
File Management and Process Scheduling
The OS is like a restaurant manager. For example, say there’s only one server in the restaurant and five customers who are queuing up for food, two of them being VIPs. Since the customers are waiting to be served sequentially, the restaurant manager/the OS has to decide how to allocate resources (the time it takes for customers to be served) based on the order that each customer was handed their menu card. It has to ensure that all customers receive their food within an acceptable time frame or risk losing business! If not handled correctly, this can lead to complications arising from arguments/tension between patrons who had different experiences dining at this once 5-star restaurants.
Processor and memory management
The operating system allocates the computer’s memory to a process when needed, but when the program is no longer running, it frees up that chunk of memory to allocate to other programs.
The operating system strives to keep the computer stable by debugging errors in the software.
The OS uses a protective lock system to keep the computer’s programs and data away from prying eyes.
Control and management
Once a computer user with an operating system switches on their computer, the central processing unit (CPU) of the machine uses commands from system software to control and manage other programs loaded onto the operating system. The device driver programming languages that facilitate this process are compiled, interpreted and stored as binaries on the hard drive. They’re responsible for translating high-level programming language commands — such as those written in Java, Python or C++ — into low-level binary commands that a CPU can understand or execute.
Difference between system software and application software
System software programs are extensions of the computer system whereas application programs are used for end users to perform specific tasks. How can you tell the difference? Applications are often installed into or run on top of the operating system — for example, Windows applications that operate in Microsoft Office. System software programs control large-scale operations within the PC itself, for example managing memory, things like disk management and device drivers should be considered system hardware. Some examples of application software include the following:
- Email clients
- Word processors
Computer operating systems are written in specialized programming languages that allow them to communicate with the computer hardware. Android is one of the most popular OS’s on cellphones today, and was created by Google Inc. Operating systems are made for any device that has a network connection. For example there is an OS called Linux which can be run on computers, game consoles, and smartphones. This means sometimes it takes more than one OS to run all of the software on these devices!
Almost all computers today come with many different kinds of software preinstalled during manufacture. Some of these pieces of software are what is considered “system” software, which means it’s always running in the background whether the computer is turned on or not. System software handles peripheral things like timekeeping or sensor or network functionality that may be used by other applications. Other pieces are application-type software, which function exactly as their name suggests – they’re used to perform specific tasks for end users.
