Concurrent Licensing
Floating licensing, also known as concurrent licensing or network licensing, is a software licensing approach in which a limited number of licenses for a software application are shared among a larger number of users over time. When an authorized user wishes to run the application, they request a license from a central license server. If a license is available, the license server allows the application to run. When they finish using the application, or when the allowed license period expires, the license is reclaimed by the license server and made available to other authorized users. The license server can manage licenses over a local area network, an intranet, virtual private network, or the Internet. Floating licensing is often used for high-value applications in corporate environments; such as electronic design automation or engineering tools. However, its use is broadly expanding throughout the software industry. An on-premise license server used to be the only way to enfo ...

Software License
A software license is a legal instrument governing the use or redistribution of software. Since the 1970s, software copyright has been recognized in the United States. Despite the copyright being recognized, most companies prefer to sell licenses rather than copies of the software because it enables them to enforce stricter terms on redistribution. Very few purchasers read any part of the license, initially shrink-wrap contracts and now most commonly encountered as clickwrap or browsewrap. The enforceability of this kind of license is a matter of controversy and is limited in some jurisdictions. Service-level agreements are another type of software license where the vendor agrees to provide a level of service to the purchaser, often backed by financial penalties. Copyleft is a type of license that mandates derivative works to be licensed under the license's terms. Copyleft licenses exist for free and open-source software, but also for commercial applications like the Ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloud Computing
Cloud computing is "a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand," according to International Organization for Standardization, ISO. Essential characteristics In 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems. Below are the exact definitions according to NIST: * On-demand self-service: "A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider." * Broad network access: "Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations)." * Pooling (resource management), Resource pooling: " The provider' ...

System Administration
An IT administrator, system administrator, sysadmin, or admin is a person who is responsible for the upkeep, configuration, and reliable operation of computer systems, especially multi-user computers, such as servers. The system administrator seeks to ensure that the uptime, performance, resources, and security of the computers they manage meet the needs of the users, without exceeding a set budget when doing so. To meet these needs, a system administrator may acquire, install, or upgrade computer components and software; provide routine automation; maintain security policies; troubleshoot; train or supervise staff; or offer technical support for projects. Related fields Many organizations staff offer jobs related to system administration. In a larger company, these may all be separate positions within a computer support or Information Services (IS) department. In a smaller group they may be shared by a few sysadmins, or even a single person. * A database administ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Software License Server
A software license server is a centralized computer software system which provides access tokens, or keys, to client computers in order to enable licensed software to run on them. In 1989, Sassafras Software Inc developed their trademarked KeyServer software license management tool. Since that time, other computing technology firms have adopted the phrase "key server" to be used interchangeably with "software license server." It is the job of a software license server to determine and control the number of copies of a program permitted to be used based on the license entitlements that an organization owns. Typically, an end-user customer organization will install a software license server on a host computer to provide licensing services to an enterprise computing environment. Publisher-specific license servers are commonly provided by software publishers, or through third party providers, to manage software licensing for a specific software publisher's products. Publisher-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Node-locked Licensing
Node-locked licensing, also known as a single use license, device license, named host license, or machine-based license, is a software licensing approach in which a license for a software application is assigned to one or more hardware devices (specific nodes, such as a computer, mobile devices, or IoT device). Typically any numbers of instances are allowed to execute for such license.{{Cite book, last1=Cai, first1=Jian-ping, last2=Qiao, first2=Li-ping, title=2009 First International Conference on Information Science and Engineering , chapter=Research and Application of the Floating License Management Strategy , date=2009, chapter-url=https://ieeexplore.ieee.org/document/5455642, location=Nanjing, China, publisher=IEEE, pages=1797–1800, doi=10.1109/ICISE.2009.889, isbn=978-1-4244-4909-5, s2cid=17429089 This form of licensing is used by software publishers to ensure the license is only run on particular hardware devices.

License Borrowing
License borrowing is a feature that allows a user to run software on a computer that is not continuously connected to the license server on the network. When making a borrow request, the user is either connected to the server over the network, or with some systems the license can be borrowed via secure file exchange between the disconnected user's system and the server. After the license has been borrowed, the user can then disconnect the computer from the network and continue to use the software for the length of the borrow period, which is typically determined by the software vendor. During this time, the borrowed license is removed from the pool of available licenses. After the borrow period expires the license is then checked back into the pool.

License Manager
A software license manager is a software management tool used by independent software vendors or by end-user organizations to control where and how software products are able to run. License managers protect software vendors from losses due to software piracy and enable end-user organizations to comply with software license agreements. License managers enable software vendors to offer a wide range of usage-centric software licensing models, such as product activation, trial licenses, subscription licenses, feature-based licenses, and floating licensing from the same software package they provide to all users. A license manager is different from a software asset management tool, which end-user organizations employ to manage the software they have licensed from many software vendors. However, some software asset management tools include license manager functions. These are used to reconcile software licenses and installed software, and generally include device discovery, soft ...

Software Metering
Software metering is the monitoring and controlling of software for analytics and enforcing of agreements. It can be either passive data collection, or active restriction. Types Software metering can take different forms: * Tracking and maintaining software licenses. Making sure that the number of concurrent users of the software do not exceed the terms of the license. This can include monitoring of concurrent usage of software for real-time enforcement of license limits. * Real-time monitoring of all (or selected) applications running on the computers within the organization in order to detect unregistered or unlicensed software and prevent their execution, or limit their execution to within certain hours. The system administrator can configure the software metering agent on each computer in the organization. * Fixed planning to allocate software usage to computers according to the policies a company specifies and to maintain a record of usage and attempted usage. A company can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concurrent User
In computer science, the number of concurrent users (sometimes abbreviated as CCU) for a resource in a location, with the location being a computing network or a single computer, refers to the total number of people simultaneously accessing or using the resource. The resource can, for example, be a computer program, a file, or the computer as a whole. Keeping track of concurrent users is important in several cases. First, some operating system models such as time-sharing In computing, time-sharing is the Concurrency (computer science), concurrent sharing of a computing resource among many tasks or users by giving each Process (computing), task or User (computing), user a small slice of CPU time, processing time. ... operating systems allow several users to access a resource on the computer at the same time. As system performance may degrade due to the complexity of processing multiple jobs from multiple users at the same time, the capacity of such a system may be measured in t ...

Plug And Play
In computing, a plug and play (PnP) device or computer bus is one with a specification that facilitates the recognition of a hardware component in a system without the need for physical device configuration or user intervention in resolving resource conflicts. The term "plug and play" has since been expanded to a wide variety of applications to which the same lack of user setup applies. Expansion devices are controlled and exchange data with the host system through defined memory or I/O space port addresses, direct memory access channels, interrupt request lines and other mechanisms, which must be uniquely associated with a particular device to operate. Some computers provided unique combinations of these resources to each slot of a motherboard or backplane. Other designs provided all resources to all slots, and each peripheral device had its own address decoding for the registers or memory blocks it needed to communicate with the host system. Since fixed assignments made expans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethernet Address
A MAC address (short for medium access control address or media access control address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer. As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator. MAC addresses are primarily assigned by device manufacturers, and are therefore often referred to as the burned-in address, or as an Ethernet hardware address, hardware address, or physical address. Each address can be stored in the interface hardware, such as its read-only memory, or by a firmware mechanism. Many network interfaces, however, suppor ...
