What Is a Global Limit?
In the IT world, users face all kinds of limits, such as how often you access a particular Web service. Some of those limits apply to individuals; global limits apply to all users, or all users in a particular group. "Global limit" also has other meanings, applying to financial applications and remote-controlled circuits.

API
-
An Application Programming Interface (API) is a tool for software to communicate with operating systems or Web-based applications. Web services place limits on how often users can access an API. For example, Shopify, a company that helps set up online stores, used to allow individual app stores to accept 300 calls every 10 minutes for downloading apps through Shopify, with a global limit of 3,000 calls every 10 minutes throughout all Shopify stores. Shopify dropped the global limit in 2011, stating it was too restrictive.

IBM's Sametime Gateway allows users of Sametime -- a system for setting up instant messaging within an organization or corporation -- to IM with members of other messaging communities. Gateway sets limits on how much server memory Sametime groups can use in IM sessions. Community limits restrict how many IM sessions any single Sametime community can engage in. Global limits are the maximum IMing that all the different communities on one network can engage in at the same time. If you have only one community in your network, only the global limit applies.

Credit

Chartis Insurance protects U.S. and Canadian companies from overseas losses due to political unrest or to customers refusing to settle their accounts. One of the services it offers is a trade credit global limit. This app allows insurance buyers and Chartis brokers to decide how much customer credit Chartis insures in different investments. If a Chartis buyer gets a higher credit limit, the customer can allocate the insured credit among various accounts, up to the global limit.
Limit Switches
-
In electronics, a limit switch is a mechanical switch that, when moved, activates or deactivates a circuit. You can flip a limit switch by hand, or trigger it with a particular stimulus, including a Wi-Fi signal. Global limit switches are radio controlled, operating in a frequency that's reserved, internationally, for wireless technology such as microwave ovens, remote controls, Bluetooth units and cordless phones. A global limit switch doesn't require any radio licensing to use.
