Operating systems operating systems (OSs) are a large group of hardware components that connect various devices to the internet.OSs have a number of distinct functions, including: operating system security : ensuring data integrity and reliability of software and data transmitted over the network, including encryption and encryption keys and security protocols; security services : providing a secure environment for data transmission and storage, such as secure sockets layer (SSL) encryption; security management : managing data on a device and enabling security features to be installed and managed on the device; security tools : providing software and software tools to secure the device and its functions; and network communications : allowing devices to communicate securely with each other, and to allow users to perform various activities, such a file transfer or file-sharing, in a secure manner.
OSs are typically installed on hardware devices such as PCs and laptops.
The purpose of OSs is to protect data, but they are also used to facilitate user interactions.OS security is a key focus of security professionals, because a compromised OS could be used to gain access to information.
OS security is essential to protecting users from malware.
In addition, OSs provide a secure computing environment for accessing and sharing files and other information.OS services are important to OS vendors to support the OSs operating system.
Operating systems also provide services to the hardware devices that provide access to the OS, such data transmission, storage, and encryption.
OS services include file and file-system management, network and data communication, and network operations.
OS Services can also include the application programming interface (API), which allows applications to communicate with one another and access data and information.
Applications that need access to data or information can perform these services.
An example of a service is the file transfer protocol, which allows file-sharers to send files over the internet to file-downloaders.
Another example of an OS service is file encryption, which protects the integrity of data in the file system and prevents unauthorized access.
