The Information Module Profile is specified in JSR 195 [11] and is designed for vending machines, network cards, routers, telephone boxes and other systems with either simple or no display and some form of limited two way network access. Only APIs for application creation, storage, and network access are defined.
This is the most basic of the CDC family of profiles. Foundation Profile is a set of Java APIs tuned for low-footprint devices that have limited resources that do not need a graphical user interface system. [4] It provides a complete Java ME application environment for consumer products and embedded devices but without a standards-based GUI system.
A keyboard matrix circuit is a design used in most electronic musical keyboards and computer keyboards in which the key switches are connected by a grid of wires, similar to a diode matrix. For example, 16 wires arranged in 8 rows and 8 columns can connect 64 keys—sufficient for a full five octaves of range (61 notes).
One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...
The configuration of a computer is typically recorded in a configuration file. In modern computer systems, this is created and updated automatically as physical components are added or removed. Applications may assume that the configuration file is an accurate representation of the physical configuration and act accordingly. [1]
The Micro-Canonical Configuration Model is the most common variation of the configuration model. It exactly preserves the degree sequence of a given graph by assigning stubs (half-edges) to nodes based on their degrees and then randomly pairing the stubs to form edges.
In earlier BIOSes, up to around the turn of the millennium, the POST would perform a thorough test of all devices, including a complete memory test. This design by IBM was modeled after their larger mainframe systems, which would perform a complete hardware test as part of their cold-start process.
The land grid array is a packaging technology with a grid of contacts, 'lands', on the underside of a package. The contacts are to be connected to a grid of contacts on the PCB. Not all rows and columns of the grid need to be used. The contacts can either be made by using an LGA socket, or by using solder paste. [2]
