Computer Technology Fundamentals Quiz

Oracle Service Bus provides extensibility through a transport SDK that allows developers to build custom transport providers. This enables OSB to communicate with proprietary protocols or specialized systems not covered by out-of-the-box transports like HTTP, JMS, or FTP. Custom transports implement standard OSB transport interfaces to plug into the messaging framework.

The Intel Pentium bug (1994) was a floating-point division error in the FPU (Floating Point Unit). The processor would produce incorrect results for certain division operations due to a lookup table error in the FPU. This affected Pentium processors but not the cache, socket, or other components.

IRQ stands for Interrupt Request, which is a signal sent to the CPU to get its attention for an event that needs immediate processing. The 'Q' in IRQ is sometimes incorrectly expanded to 'Queue', but the correct expansion is simply 'Interrupt Request' - there is no word starting with Q in the expansion.

A Cathode Ray Tube (CRT) is the display technology used in traditional computer monitors and televisions. It uses electron beams to illuminate phosphors on the screen. CRTs are not found in CPUs, printers, or scanners - those are different types of hardware components.

A scanner is an input device that converts physical documents to digital format. Unlike floppy disks, email attachments, or internet downloads, scanners do not execute or transfer executable code - they only create image files. Therefore, a computer virus cannot be contracted from a scanner alone.

A cookie is a small text file stored on a user's computer by a web browser. It contains information about the user's browsing activity and preferences for that specific website. Cookies are not cooking software, websites themselves, or hacker files - they are data files used for state management.

The standard 3.5-inch floppy disk, when formatted, has a capacity of 1.44MB (megabytes), not 1.44K (kilobytes). Options A and D are incorrect - 2MB and 120MB were not standard floppy sizes. The 1.44MB format was the most common PC floppy disk standard.

JPEG, GIF, and BMP are all image file formats used for storing digital images. TMP, however, is a generic file extension for temporary files and is not specifically an image format. TMP files can contain any type of temporary data depending on the application that created them.

The first Intel Celeron processor (Covington core) lacked Level 2 cache entirely, which significantly reduced its performance compared to the Pentium II. While it was error-free and didn't have heat issues, the absence of L2 cache was its major limitation and the primary reason for lower performance and lack of popularity.

UNIX is not an acronym. The name was derived from 'Multics' as a pun, but it does not stand for any specific phrase. Options like 'UNIt eXchange' and 'UNIform eXchange' are backronyms invented after the fact.

Hard disk drives store data using magnetic technology - tiny magnetic domains on spinning platters represent binary data. Laser and light are used in optical storage (CDs, DVDs), while chemical storage is not used in consumer HDDs.

Ping tests network connectivity, Winipcfg displays IP configuration on Windows, and Tracert traces packet routes. 'Netcfg' is not a standard network command - these others are legitimate diagnostic tools.

Internet Explorer, Netscape, and Opera are all web browsers. Hotmail is a web-based email service, not a browser - it runs inside a browser but is not itself one.

Cable Internet uses broadband technology capable of high data rates. 28.8k and 56K are dial-up modem speeds (narrowband), and 'modem' alone typically refers to these slow dial-up connections.

.AVI (Audio Video Interleave) is a standard video file format for PCs. .MP3 is audio-only, .MVE is a less common video format, and .VDO is not a standard video extension.
