PXE

Pre-boot eXecution Environment. A standard of WfM that allows networked computers that do not have an OS to be configured and started remotely. PXE benefits include:

The client computer does not necessarily need its own OS or even a hard drive.

The client computer can be remotely shut down and restarted.

Since PXE is an industry standard, new computers can easily be added to the network.

RAID

Redundant Array of Independent Disks. A system of two or more drives working together for performance and fault tolerance. RAID drives are typically used on servers and high-endPCs.

There are a number of different RAID levels. The three most common are 0, 3, and 5:

Level 0: Provides data striping but no redundancy. This improves performance but does not provide fault tolerance.

Level 3: Same as Level 0, but also reserves one dedicated drive for error correction data, providing good performance and some level of fault tolerance.

Level 5: Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance.

RAM

Random-access memory. The primary temporary storage area for program instructions and data. RAM is stored in chips on small circuit boards called SIMMs, DIMMs, or RIMMs, that attach to the system board. RAM, unlike ROM, is volatile, which means that, when you turn off your computer, any information stored in RAM is lost.

Rambus

Rambus is a memory technology that is designed to work with existing system board standards as an alternative to DRAM. See also RIMM, RDRAM, and

DRDRAM.

RDRAM

Rambus dynamic random-access memory (DRAM). A memory subsystem that can optimally transfer up to 1.6 billion bytes of data per second. The subsystem consists of RAM, the RAM controller, and the bus connecting RAM to the microprocessor and other devices in the computer. See also

DRDRAM.

GX240 specifications

The Dell GX240, a robust desktop computer released in the early 2000s, exemplifies the breed of machines engineered for business and productivity environments. Targeting corporate users, the GX240 was part of Dell’s OptiPlex series, known for its reliability, support, and manageability.

One of the main features of the Dell GX240 is its Intel Pentium 4 processor, which provided a significant performance boost at the time of its release. This processor was available in various speeds, enabling users to select the model that best met their processing needs. The GX240 also offered ample memory options, supporting up to 2GB of SDRAM, which was considerable for its era, allowing for smoother multitasking and application performance.

The design of the GX240 was practical, featuring a compact, space-saving chassis ideal for office environments. It was designed for easy serviceability, with tool-less access to components, facilitating quick upgrades or repairs. The system was equipped with various configurations, enabling customers to customize it with multiple hard drive options, typically using IDE drives, which provided sufficient storage for everyday tasks.

The desktop utilized a variety of expansion slots, including AGP for graphics cards and PCI slots for additional peripherals. This expandability was crucial for businesses needing to adapt or enhance their systems over time. Integrated Intel graphics were standard, but users could opt for dedicated graphics cards to meet more demanding graphical needs.

Connectivity was also a strong point for the GX240, featuring multiple USB 2.0 ports, a serial port, and audio input/output capabilities. These ports allowed for seamless integration with various peripherals and devices, essential for a productive work environment. The GX240 also supported network connectivity through a built-in Ethernet controller, making it well-suited for office use, especially in networked environments.

In terms of software, the GX240 was usually shipped with Microsoft Windows XP, ensuring users had access to a stable and user-friendly operating system. This operating system not only provided compatibility with a wide range of applications but also enhanced the overall user experience.

In conclusion, the Dell GX240 was a solid desktop choice for businesses in the early 2000s, combining performance, upgradability, and a compact design. Its Intel Pentium 4 processor and ample memory options made it suitable for various tasks, while its space-saving design and expansion capabilities allowed businesses to adapt the system to their evolving needs.
