Network Cables

Networking cables are used to connect one network device to other network devices or to connect two or more computers to share printer, scanner etc. Different types of network cables like Coaxial cable, Optical fiber cable, Twisted Pair cables are used depending on the network's topology, protocol and size. The devices can be separated by a few meters (e.g. via Ethernet) or nearly unlimited distances (e.g. via the interconnections of the Internet).

While wireless may be the wave of the future, most computer networks today still utilize cables to transfer signals from one point to another.

Microsoft PowerToys

Microsoft PowerToys is a set of programs provided by Microsoft for the Windows operating system. PowerToys are not integrated into Windows since they are released after the public release of a Windows operating system. They are also not under technical support because they do not undergo the same rigorous testing that the operating system components do.

Windows Imaging Format (WIM)

The Windows Imaging Format (WIM) is a file-based disk image format. It was developed by Microsoft to help deploy Windows Vista and subsequent versions of Windows operating system family, as well as Windows Fundamentals for Legacy PCs.

Patch Computing

A patch is a piece of software designed to fix problems with, or update a computer program or its supporting data. This includes fixing security vulnerabilities and other bugs, and improving the usability or performance. Though meant to fix problems, poorly designed patches can sometimes introduce new problems (see software regressions). In some special cases updates may knowingly break the functionality, for instance, by removing components for which the update provider is no longer licensed or disabling a device.

System hang

In computing, a hang or freeze occurs when either a single computer program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a workstation with a graphical user interface, all windows belonging to the frozen program become static, and though the mouse cursor still moves on the screen, neither typing on the keyboard nor clicking the mouse produces any effect in the program's windows. The mouse cursor may also be stuck in a form indicating that it is waiting for some operation to complete, such as an hourglass or a spinning wait cursor.

Many modern operating systems provide the user with a means to terminate a hung program without rebooting or logging out. In more severe hangs affecting the whole system, no window belonging to any program will respond to keyboard or mouse input, and often the mouse cursor will freeze in place on the screen. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.

In the Windows 7 and Windows Vista operating systems, hangs almost always precedes a Blue Screen of Death or are a sign to the user that one is on its way[citation needed]. On Windows systems, if clicked on, a hanging program will gain "Not Responding" in parentheses on its top bar.

A hang differs from a crash, in which a program exits abnormally or the operating system shuts down.
Hangs are not limited to client personal computers with a graphical user interface, as in the example above. Servers can hang as well. In those cases, the server ceases to respond to requests. These sorts of hangs are typically addressed by a solution far more complex than an on/off or reset button.

Pre-emptive multitasking operating systems, such as Microsoft Windows 2000/XP/Vista/7, Apple Computer's Mac OS X and Linux hang less often as the multi-tasking system is not affected by non-terminating loops and further does not require tasks to yield control to the operating system. If a task does hang, the scheduler may switch to another group of interdependent tasks so that all processes will not hang.

Computing Compatibility

Computing

   1. Backward compatibility, in which newer devices can understand data generated by older devices
   2. Compatibility card, an expansion card for hardware emulation of another device
   3. Compatibility layer, components that allow for non-native support of components
   4. Compatibility mode, software mechanism in which a software emulates an older version of software
   5.  Computer compatibility, of a line of machines
   6. Forward compatibility, in which older devices can understand data generated by newer devices
   7. License compatibility, of software licenses
   8. Pin-compatibility, in devices that have the same functions assigned to the same particular pins

Configuration Computer System

In communications or computer systems, a configuration is an arrangement of functional units according to their nature, number, and chief characteristics. Often, configuration pertains to the choice of hardware, software, firmware, and documentation. The configuration affects system function and performance.

The Wu Xing

The Wu Xing, (五行 wŭ xíng) also known as the Five Elements, Five Phases, the Five Agents, the Five Movements, Five Processes, and the Five Steps/Stages, is a fivefold conceptual scheme that many traditional Chinese fields used to explain a wide array of phenomena, from cosmic cycles to the interaction between internal organs, and from the succession of political regimes to the properties of medicinal drugs. The "Five Phases" are Wood (木 mù), Fire (火 huǒ), Earth (土 tǔ), Metal (金 jīn), and Water (水 shuǐ). This order of presentation is known as the "mutual generation" (xiangsheng 相生) sequence. In the order of "mutual conquest" (xiangsheng 相勝) or "mutual overcoming" (xiangke 相剋), they are Wood, Earth, Water, Fire, and Metal.

The International System of Units

The International System of Units (abbreviated SI from French: Le Système international d'unités) is the modern form of the metric system. It comprises a coherent system of units of measurement built around seven base units, 22 named and an indeterminate number of unnamed coherent derived units, and a set of prefixes that act as decimal-based multipliers. The standards, published in 1960, are based on the metre-kilogram-second system, rather than the centimetre-gram-second system, which, in turn, had several variants. The SI has been declared to be an evolving system; thus prefixes and units are created and unit definitions are modified through international agreement as the technology of measurement progresses, and as the precision of measurements improves. SI is the world's most widely used system of measurement, used in both everyday commerce and science.

The system has been nearly globally adopted. Burma, Liberia and the United States have not adopted SI units as their official system of weights and measures. The U.S. does not commonly use metric units outside of science, medicine, and the government, but has officially defined its customary units in terms of SI units. The United Kingdom has officially adopted a partial metrication policy, with no intention of replacing imperial units entirely. Canada has adopted it for most purposes but imperial units are still legally permitted and remain in common use throughout a few sectors of Canadian society, particularly in the buildings, trades and railways sectors.

Electric power

Electric power is the rate at which electric energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.

Electric power is usually produced by electric generators, but can also be supplied by chemical sources such as electric batteries. Electric power is generally supplied to businesses and homes by the electric power industry.
