Well, a shared resource is something that is like a natural resource but it is shared so that makes it a "Shared Resource".

What is the url used for?
A URL (Uniform Resource Locator, also less commonly called a URI, the Uniform Resource Identifier), allows a program to locate a particular piece of data. It includes a protocol handler (such as HTTP, FTP, etc), a host name (the domain name or IP address of the other end of the connection), and a path to a particular resource. It is used to access a file or other shared resource available on a network.
Which access control model allows the owner of the resource to choose who can access the resource?
Discretionary access controlnswer Explanation: The discretionary access control (DAC) model permits the owner of a resource to identify the users who can access the resource. You become the owner of the resource by either creating the resource or by being granted ownership of that resource. You grant access to the resources using access control lists (ACLs).
What does a server url means?
url = uniform resource locator or universal resource locator, this is the address of a specific internet site or resource.
What are the two parts of a uniform resource?
the protocol identifier and the resource name
What are the two parts of a Uniform Resource Locator?
the protocol identifier and the resource name
What is resource sharing?
Well, a shared resource is something that is like a natural resource but it is shared so that makes it a "Shared Resource".
Which resource cannot be shared on a network?
keyboard
What information can be shared on lan and wan?
Any information or resource can be shared; it is up to the sharing account as to what they want to share.
Is explicit deny the default security principle of a shared resource's ACL?
implicit deny
What is smart pointer in C plus plus?
A smart pointer is a resource handle. There are three types of smart pointer: unique, shared and weak (std::unique_ptr, std::shared_ptr and std::weak_ptr, respectively). A unique pointer "owns" the resource it refers to and will destroy that resource when the pointer falls from scope. Unique pointers can be moved (transferring ownership between the pointers) but they cannot be copied. Aside from that, they behave exactly as a "naked" pointer would and incur no runtime overhead. Unique pointers are the ideal method of implementing RAII (resource acquisition is initialisation) because they provide the basic guarantee (no resource leaks). Shared and weak pointers work together to provide shared ownership. A shared pointer "owns" the shared resource while a weak pointer does not. In order to access the shared resource via a weak pointer, the weak pointer must first be converted to a shared pointer to assume temporary ownership. If the original shared pointer falls from scope during this time, the resource's lifetime is extended until the temporary shared pointer falls from scope. Weak pointers can also be used to break circular references between shared pointers. Although there is a runtime cost in using shared pointers, the cost is close to optimal compared with manual solutions using "naked" pointers, but with a much reduced maintenance burden. In multi-threaded applications, shared resources are often inevitable, but are best avoided whenever possible. However, writing lock-free code makes code difficult to maintain, thus shared pointers can often provide a convenient compromise.
Difference between priority inheritance and priority ceiling protocol?
priority inheritance: when a job blocks one or more high priority jobs, it ignores its original priority assignment and executes its critical section at the highest priority level of all the jobs it blocks.priority ceiling: gives each shared resource a predefined priority ceiling. When a task acquires a shared resource, the task is hoisted (has its priority temporarily raised) to the priority ceiling of that resource. It will not see whether the job has been blocked or not, simply it raises to the priority of the shared resource.
What are the main problem of shared use?
The main problems of shared use include lack of privacy, potential conflicts over resource allocation, difficulties in coordinating schedules and responsibilities, and challenges in maintaining cleanliness and orderliness in shared spaces.
What is the main purpose of mapping network drives?
It provides a convenient way of accessing a shared resource such as a folder, file or printer.
How does semaphore solve mutual exclusion problem?
Mutual exclusion is an issue in concurrent programming when two concurrent processes are attempting to access the same shared resource and neither can complete their process because the other is blocking it. A semaphore controls access to the shared resource, ensuring that one process is completely finished before a second can access it.
What is the purpose of synchronization?
Purpose of synchronization block is to lock an object for any shared resource. Scope of synchronized block is smaller than the method.
What represents earths modern commons?
Shared Natural Resources
What happens if a security group that's an ace in a shared folder is converted to distributed group?
The group remains in the DACL, but the ACE has no effect on members' access to the resource.
