listen to the pronunciation of scalability
English - Turkish
Ölçeklenebilirlik
English - English
The capability to use the same software environment on many classes of computers and hardware configurations Although often associated with an evolution to large systems, larger organizations often have need for the same software service to be provided with good performance to both small and large groups of users
How well a system can adapt to increased demands For example, a scalable network system would be one that can start with just a few nodes but can easily expand to thousands of nodes
In one sense, it is the ability to meet ever-expanding demands In another sense, it is an application capable of operating in small business to enterprise environments
The ability to expand the number of users or increase the capabilities of a computing solution users without making major changes to the systems or application software
{i} ability to adjust configuration and size to fit new conditions; (Computers) ability to change the scaling of an application; ability to expand the capabilities of a computer; ability to change the size of a font or picture
the quality of being scalable
Scalability is the capability of a product (hardware or software) to function well as it scales up or down to meet a user's needs For example, a router (hardware) with one WAN port is said to be scalable if it can be scaled up to support more than one WAN port or down (back to one WAN port) through the addition or removal of WAN modules
The ability of a technology to handle larger and larger workloads
Refers to how much a system can be expanded The term by itself implies a positive capability For example, "the device is known for its scalability" means that it can be made to serve a larger number of users without breaking down or requiring major changes in procedure
The ability of a system to handle increased volume or complexity
The ability of a software program to continue to function smoothly as additional volume, or work is required of it
The ability to maintain high performance levels despite a significant increase in database size and/or workload
The measure of a system's ability to increase or decrease in performance and cost in response to changes in application and system processing demands Examples would include how well a hardware system performs when the number of users is increased, how well a database withstands growing numbers of queries, or how well an operating system performs on different classes of hardware Enterprises that are growing rapidly should pay special attention to scalability when evaluating hardware and software
The ability to expand a computing solution to support large numbers of users without impacting performance
The ability of a computer application or product (hardware or software) to continue to function well as it (or its context) is changed in size or volume in order to meet a user need
The property of being scalable
The ability to increase the size and processing power of an online transaction processing system by adding processors and devices to a system, systems to a network, and so on, and to do so easily and transparently without bringing systems down Sometimes called expandability
The ability of a phone system to grow (add lines, extensions, or applications) along with your company
The ability to use the same application software on many different classes of hardware/software platforms from personal computers to super computers (extends the portability concept) The capability to grow to accommodate increased work loads
The ability of a system to incrementally increase connectivity and performance
The ability to support evolving space and bandwidth needs as business needs grow Synchronous Optical Network (SONET) A group of fiber optic transmission systems laid out in a physical ring, ideally, to provide redundancy and the flexibility needed to transport many digital signals with different capacities
A property of physical implementations of information processing that implies that there are no bounds on accurate information processing That is, arbitrarily many information units can be realized and they can be manipulated for an arbitrarily long amount of time without loss of accuracy Furthermore, the realization is polynomially efficient in terms of the number of information units and gates used
the degree to which a computer system is able to grow and become more powerful as the number of people using it increases

The ability to support the required quality of service as the system load increases without changing the system
The extent to which developers can apply a solution to problems of different sizes Ideally, a solution should work well across the entire range of complexity In practice, however, there are usually simpler solutions for problems of lower complexity
the capability of a technological resource (application, service, standard, etc ) to expand or to handle an increase in data
The ability to add power and capability to an existing system without significant expense or overhead An "economy of scale" exists when a small increase in load produces a less-than-linear increase in overhead A "diseconomy of scale" exists when a small increase cause a significant increase in overhead
The measure of a service's ability to increase or decrease in performance and cost in response to Changes in throughput or demand
