Computer Tutorials: What is Windows Registry?

Computer Registry or popularly known as Windows Registry is a central storage area of different kinds of data from all parts of a computer system. Specifically, it consists of information coming from the hardware settings, applications stored, Operating system used and the users of that particular computer unit. Modern version of Windows Registry such as the ones found in Windows 9x, have already combined the REG.DAT and INI files. Its obvious advantage from its older version is the easy access of varied files. It is also ideal for massive structured data due to its simple hierarchy.

When inspecting a Windows Registry, one may think that all of the data came from a single source. Actually, the displayed data is stored on different physical files. User-specific information are stored in USER.DAT while computer-specific information is stored in SYSTEM.DAT.

Its architecture is well organized therefore it is easy to understand. On the left part of the display is the registry tree while on the right pane is a list of data. The tree is divided into 6 parts which are called root keys or top-level keys. They can be easily identified because their names would usually start with HKEY_. Each top level key holds sub keys. These sub keys could also contain a set of sub keys. The lowest levels of keys are called values.

Applications use the registry by adding or deleting a key. Consequently it can also create and delete the value from a key. Frequent installation and removal of programs in a computer could cause invalid and missing keys, which in turn causes the system to crash and the computer to slow down. Constantly removing of hardware and spywares on a computer also adds up problems to your Windows system registry.

It is possible to view and edit the registry using the Registry Editor provided by your operating system. Or you could also opt using the third party editors. However, it is strongly suggested to stick with the Microsoft product. Great care must be considered in editing the registry. Errors in registry could seriously immobilize your computer. But if you are equipped with the right knowledge and technical know-hows editing the registry would be an easy task.

Computer Tutorials: How an OS works

The Operating System of a computer plays an integral role in carrying out different computing tasks simultaneously. If the CPU is referred as the “brain of the computer” then, the OS is definitely the “soul of the system”. It integrates the hardware and software parts of your computer to be able to establish a smooth flow in performing computer applications and user interactions. Advanced OS now even have the capability to adapt to the needs of the users that change over time. But how does it do all of these?

Basically, an OS is assigned to do two tasks. First, it controls and manages the computer resources (e.g. memory, CPU, storage, hardware, device drivers, applications and input and output devices) and designates it to the applications that need it to run properly. It does this without compromising other ongoing applications. It also makes sure that the computer has fully achieved its best performing capacity by utilizing the hardware and software resources efficiently. Its second task is to ensure stability in the system’s total operations despite hardware changes and computer upgrades. It provides API (Application Program Interface) stability and consistency. This allows users to modify or write programs on a computer without having to trouble themselves from the problem of being able to run it on a separate desktop or laptop. So that even though the computer hardware undergoes modifications and updates, there is an assurance that the applications would continually to run.

Understanding how the Operating system works is a key element in modifying its behavior so as to meet your varied computing needs and be able to use this to your advantage.
