OASIS:
Stands for "Organization for the Advancement of Structured Information Standards." To someone backpacking through the Sahara, this is not the type of OASIS you want to see. But is it a welcome sight in the computer science world. OASIS is a non-profit, global consortium that supports the development and adoption of e-business standards.
While it won't quench your thirst in the middle of the desert, OASIS does provide several useful technology standards. Common standards regulated by the OASIS consortium include protocols, file formats, and markup languages. Hardware and software companies often work with OASIS to develop and institute standards that are efficient and effective.

OEM- Stands for "Original Equipment Manufacturer." This refers to a company that produces hardware to be marketed under another company's brand name.
OOP: Stands for "Object-Oriented Programming." OOP refers to a programming methodology based on objects, instead of just functions and procedures. These objects are organized into classes, which allow individual objects to be group together. Most modern programming languages including Java, C/C++, andPHP, are object-oriented languages, and many older programming languages now have object-oriented versions..

An "object" in an OOP language refers to a specific type, or "instance," of a class. Each object has a structure similar to other objects in the class, but can be assigned individual characteristics. An object can also call functions, or methods, specific to that object. For example, the source codeof a video game may include a class that defines the structure of characters in the game. Individual characters may be defined as objects, which allows them to have different appearances, skills, and abilities. They may also perform different tasks in the game, which are run using each object's specific methods.

Object-oriented programming makes it easier for programmers to structure and organizesoftware programs. Because individual objects can be modified without affecting other aspects of the program, it is also easier to update and change programs written in object-oriented languages. As software programs have grown larger over the years, OOP has made developing these large programs more manageable.

Optical Drive: An optical drive is a type of computer disk drive that reads and writes data from optical disks through laser beaming technology. This type of drive allows a user to retrieve, edit and delete the content from optical disks such as CDs, DVDs and Blu-ray disks. Optical drives are among the most common computer components. An optical drive may also be known as an optical disk drive (ODD).

Output: Data generated by a computer is referred to as output. This includes data produced at a software level, such as the result of a calculation, or at a physical level, such as a printed document. A basic example of software output is a calculator program that produces the result of a mathematical operation. A more complex example is the results produced by a search engine, which compares keywords to millions of pages in its Web page index.

Overclocking:
Overclocking involves increasing theclock speedof the computer'sCPUpast the rate at which it was originally designed to run. Some ways to overclock a processor include increasing the CPU's operating speed in the systemBIOSor changing the hardwarejumpersettings for the processor. Modifying these settings may allow the processor to run faster than set by the manufacturer, which may increase the overall performance of the computer. However, since other settings, such as the memory speed,frontsideandbacksidebus speeds, and other components are fixed, there may not be a significant increase in performance.Regardless of how overclocking is done, it potentially may cause problems with the computer. After all, when you overclock a computer, you are altering the manufacturer's design of the machine. For example, if there is not enough electrical current to to power the processor at the new rate, it may slow down or stop running completely. Also, if theheat sinkcannot sufficiently cool the processor running at the faster rate, it may overheat, causing your computer tofreezeor crash. This is actually a preventive measure, since the computer stops functioning when the CPU gets too hot. Otherwise, the CPU may literally fry itself and your overclocked processor may become an overcooked processor. In summary, overclocking a processor can be a risky endeavor. It is best left to computer enthusiasts who understand their hardware and are willing to accept the risks associated with it. Since overclocking voids your computer's warranty, don't expect the manufacturer to replace your cooked CPU for free. If you want a fast machine that is supported by the manufacturer, buying a fast processor to begin with is your best bet.
Overwrite-In computing, overwriting refers to replacing old data with new data.
