PC software is a collection of tools and programs created to make your computer more efficient, productive or enjoyable. Examples include word processors, music and multimedia players, video games and graphics and design software. Security programs can protect your computer from viruses and malware. And optimisation programs can clean up junk files, repair the Registry and free up disk space.
System software
System software, which runs on a computer’s hardware and provides an interface to user applications, is vital to its operation. Without it, the computer cannot run application software.
System-level functions include memory management, processor management, and file management. It also enables security by preventing unauthorized access to programs and data. Additionally, it can perform system logs and produce performance analysis aids for detecting errors and improving application efficiency.
System software is closer to the computer hardware and operates in a low-level computer language. It is fast in working speed and difficult to manipulate, and is less interactive for the user than application software. It is often updated to improve usability and functionality, or to patch vulnerabilities. It is also responsible for providing a framework on which application software can operate, like a virtual machine. It may consist of devices drivers for a variety of computer hardware such as printers, mice, keyboards, and scanners. This category also includes various programmers’ tools, including debuggers and compilers.
Application software
Application software includes programs that perform specific tasks for users, such as word processing and video games. These programs make computers and technology more accessible and efficient for everyday use. Application software can be grouped into horizontal and vertical categories, with the former being general purpose software and the latter being tailored to specific industries or business departments.
Spreadsheet software is a common example of horizontal application software, which allows you to manage data with a spreadsheet. Other examples include word processors, graphic design software, and e-mail applications. These programs are usually designed to be compatible across platforms, enhancing accessibility and compatibility.
Stimulation software is another type of application software, which is used in the military, engineering and practical education industry, machinery testing and industrial training. It helps people experience difficult situations without putting themselves in danger. It is also used in video games to enhance gameplay and immersion. Security and optimisation are two other important functions of application software.
Drivers
Drivers are the software that allow your operating system to interact with hardware devices, like a printer or graphics card. They act as digital interpreters that translate instructions from your operating system into a language the device understands. Without them, your computer would not be able to function properly.
Computer drivers can be classified into different categories, including user-mode and kernel mode drivers. Kernel-mode drivers are loaded along with the OS and run at a high privilege level within the OS runtime environment. User-mode drivers, on the other hand, are loaded by the OS in the user mode and are more lightweight. They also tend to be transparent, meaning their source code is available for anyone to check.
Drivers are an important component of a computer, and should be updated regularly to ensure optimal performance. Updating your drivers can improve gaming and resource-heavy applications, as well as protect your computer against security vulnerabilities. Download IOBIT Driver Booster to scan your PC and automatically update any outdated drivers.
Security software
Security software is any program that plays a dedicated role in securing the computer and its data. This includes authenticating systems, firewall operating systems, and intrusion detection software. Security programs can also provide features like privileged user control, access controls, and encryption.
Advanced malware protection features monitor the activity of applications to ensure they’re not stealing sensitive information or exposing the system to dangerous hacks. It can prevent breaches, and gives the visibility, context, and control needed to quickly detect, contain, and remediate threats that evade frontline defenses.
Most suites offer a system tune-up component that clears traces of browsing and other activities, and some include privacy-related features like foiling keyloggers and protecting online banking sessions with a hardened browser. Some suites, like Trend Micro Maximum Security, take things up a notch with a capable VPN and password management tools. Others, such as Bitdefender Total Security, go the extra mile with cloud-based backup and a unique anti-theft component.
