OHCI

Reading: O h sea eye
Full spelling: Open Host Controller Interface
Field:
Personal computer > I/O > serial /USB > USB > OHCI

One of types of USB controller which controls the communication of the peripheral device and the computer itself of USB connection. OHCI system and UHCI (Universal Host Controller Interface) there are 2 types of system in the USB controller, control method and the driver etc differ.

OHCI the Microsoft corporation and the National Semiconductor corporation etc being center, with the standard which is decided, is loaded, onto the chip set of most manufacturers other than Intel corporation and the VIA corporation such as ALi corporation, SiS corporation and OPTi corporation.

Because bus master transfer is supported, there is a feature that you do not apply load on CPU of the computer itself excessively.

Presently, as for the bender which sells the USB equipment from the fact that the driver where the majority corresponds to the both of OHCI and UHCI is offered, as for the user as for the necessity to designate the difference of both excessively as the air it is not.

OLAP Online analysis processing

Reading: O lap
Full spelling: On-line Analytical Processing
Field:
Software > database > OLAP

The system which analyzes the database to which enterprise accumulates the customer data and the sale data multidimensionally, visualizes. Using the data warehouse, and the like it houses the mass original data which was gathered in the multidimensional database, this it searches & totals from various angles and discovers the problematical point and solution. For example, purchase past record of the customer is analyzed, classified by area and the classified by product and classified by month and the like can sale analyze instantaneously from various dimensions. It is not information technology section, the human of the section which needs the analytical result (the end user) operating the system directly, the point which does analysis differs from the former analysis system. From the difference of the design it is roughly classified to 2 types of ROLAP and MOLAP.

In Windows, between the application software the mechanism in order it transfers & to share the data.

In the document which is drawn up with a certain application software by using OLE, the information which was drawn up with another application software is imbedded, like whether function of another application software just you are your own function of, it reaches the point where it can offer.

OLE 1.0 which appears in 1991 was loaded onto Windows 3.1. OLE2 which expands function substantially appeared in 1993, was loaded onto Windows 95. Those which add the performance because it corresponds to Internet appeared in 1996, also name was changed to “ActiveX”.

OLE DB

Reading: [oeruideibi]
Full spelling: Object Linking and Embedding DataBase
Field:
Windows > Programming > OLE DB
Software > database > OLE DB

It was developed by the Microsoft corporation, programming interface in order to access the database with standardized technique with the type of database. ODBC is the portion of OLE DB, the expedient which is accessed the relational database is offered. OLE DB is actualized the COM based component (the program part) as the aggregate, is designed in such a way that it can utilize from with any programming language.

OLE control

Reading: [oeruikontororu]
Field:
Windows > Execution environment > OLE control
Programming > object oriented > OLE control

Conforming to OLE which is the mechanism which actualizes the data cooperation between the application software in Windows, the software part which was drawn up. With only the function of specification, size is small. Independently it is not possible, installs in the application software and uses to execute. Rather than enterprise draws up the respective company peculiar processing unites to the application software of marketing and as OLE control, developing the private application software from 0 by it is with using densely, low it is possible to draw up the custom application software in cost. Because in 1996 OLE name it is modified in ActiveX, it reached the point where also OLE control is called ActiveX control.

OLGA

Reading: [oruga]
Full spelling: Organic Land Grid Array
Field:
Microprocessor > x86/Intel > Intel > OLGA

One of mounted form of microprocessor core of Intel corporation. The point which does not cover the processor core with the plastic cover, has made bare is a special feature. Mobile Pentium Pentium II after II and 350MHz, Pentium III and being something which is adopted for Pentium 4 and the like, with Pentium II/III it was combined with the SECC2 cartridge. The core heat dissipation efficiency is raised by the fact that it makes contact with the CPU fan immediately, also the core itself is miniaturized. In the SECC2 cartridge PGLA (Plastic Land Grid Array) with there was a type which is said in other things, but as for the core of OLGA because PGLA compared to it is thin shape, size of the fan which is installed differed. In addition, as for the core of OGLA because it is brittle, note is necessary in handling.
