Installation (or setup) of a computer program (including device drivers and plugins), is the act of making the program ready for execution. Installation refers to the particular configuration of software or hardware with a view to making it usable with the computer. A soft or digital copy of the piece of software (program) is needed to install ...
Start Input/Output differs from EXCP (including XDAP, which is simply a DASD-only subset of EXCP) and EXCPVR in the following fundamental way: Start Input/Output is a low level facility that supports, e.g., selection of channel paths, selection of exposures while Execute Channel Program is a high level facility that supports, e.g., CCW translation, page fixing, serialization of related ...
These requirements are almost always of a significantly higher level than the minimum requirements, and represent the ideal situation in which to run the software. Generally speaking, this is a better guideline than minimum system requirements in order to have a fully usable and enjoyable experience with that software.
Devices for communication between computers, such as modems and network cards, typically perform both input and output operations. Any interaction with the system by an interactor is an input and the reaction the system responds is called the output. The designation of a device as either input or output depends on perspective.
The new I/O architecture used a 16-bit subchannel number, a 16-bit device number and an 8-bit Channel Path Identifier (Channel Path Id or CHPID); the Channel Subsystem was responsible for mapping the subchannel number to the channel and device numbers, for queuing I/O requests and for selecting from the available paths.
This can be done to upgrade a device [7] or to change the provider of a service associated with the function of the device, such as changing from one mobile phone service provider to another or installing a new operating system. If firmware is upgradable, it is often done via a program from the provider, and will often allow the old firmware to ...
In the context of installing firmware onto a device, a programmer, device programmer, chip programmer, device burner, [1]: 364 or PROM writer [2] is a device that writes, a.k.a. burns, firmware to a target device's non-volatile memory.
There are potential weaknesses in the implementation of the protocol between the dongle and the copy-controlled software. For example, a simple implementation might define a function to check for the dongle's presence, returning "true" or "false" accordingly, but the dongle requirement can be easily circumvented by modifying the software to always answer "true".
