Characteristics of Operating System

Characteristics of Operating System

Here is a list of some of the most prominent characteristic features of Operating Systems
●Memory Management − Keeps track of the primary memory, i.e. what part of it is in use by whom, what part is not in use, etc. and allocates the memory when a process or program requests it.
●Processor Management − Allocates the processor (CPU) to a process and deallocates the processor when it is no longer required.
●Device Management − Keeps track of all the devices. This is also called I/O controller that decides which process gets the device, when, and for how much time.
●File Management − Allocates and de-allocates the resources and decides who gets the resources.
●Security − Prevents unauthorized access to programs and data by means of passwords and other similar techniques.

10.5. Identity and Access Management (IAM) in Cloud Computing

10.5. Identity and Access Management (IAM) The identity and access management (IAM) mechanism encompasses the components and policies necessary to control and track user identities and access privileges for IT resources, environments, and systems. Specifically, IAM mechanisms exist as systems comprised of four main components: • Authentication – Username and password combinations remain the most common forms of user authentication credentials managed by the IAM system, which also can support digital signatures, digital certificates, biometric hardware (fingerprint readers), specialized software (such as voice analysis programs), and locking user accounts to registered IP or MAC addresses. • Authorization – The authorization component defines the correct granularity for access controls and oversees the relationships between identities, access control rights, and IT resource availability. • User Management – Related to the administrative capabilities of the system, the user manag
