A technology agreement was made by Duracell/Toshiba/Varta in 1992, strategically aimed at the portable computer field. In 1994 a joint venture, "The 3 C Alliance" was formed. Standardization of the inventory was the main point. The benefits were seen to be easier replacement and lower cost per unit ( 170 for 6 h ). One of the first commercial partners was Compaq Computer Co. 

All of our calculations were performed with the Gaussian98 suite [11] of codes on AMD Athlon 2000+ 1.6 GHz and Pentium IV 1.7 GHz computers, as well as on SGI 0rigin2000 and Compaq Sierra systems. The three-dimensional plots of molecular orbitals were generated with the MOLDEN program [12]. 

Computer clusters contain a number of processors put together on a motherboard into a unit known as a node. The nodes are then hooked together with other boards via high-speed communications networks. Nodes can be hardwired into supercomputers produced by companies like IBM and Compaq or... 

All calculations were carried out on a Compaq GS160 minisupercomputer at Brussels Free University and on a Linux farm consisting of dual-CPU 2GHz and 2.4Ghz Pentium Xeon workstations at the Weizmann Institute of Science. 

The operating system used is Windows 2000 Professional, version 5.0, the application software is MS Excel 2000 SR-1. Validation was performed using a Compaq Deskpro EN, serial number..., containing a... processor.

These motherboard form factors are usually found in what are known as clone computers (those not manufactured by a Fortune 500 PC company). Some manufacturers (e.g. Compaq and IBM) design and manufacture their own motherboard designs, which really don t conform to either standard. This style of motherboard is known as a proprietary design motherboard. Basically, the components are laid out differently than an AT or ATX, but it will work as a PC. The components are laid out differently than the motherboards previously discussed. 

Aside from the processor, the most important chip on the motherboard is the basic input/output system (BIOS) chip. This chip is a special memory chip that contains the BIOS software that tells the processor how to interact with the rest of the hardware in the computer. The BIOS chip is easily identified if you have a non-clone computer (e.g. Compaq, IBM, HP, etc.), this chip will have the name of the manufacturer and usually the word BIOS. For example, the BIOS chip for a Compaq will say something like Compaq BIOS on it. For clones, the chip will usually have a sticker or printing on it from the three major BIOS manufacturers (AMI, Phoenix, and Award). 

Most portable computers fall into one of three categories luggable, laptop, or PDA. Luggable computers were the first truly portable computers, although some of their owners would beg to differ with me. Compaq computer made some of the first luggable computers. ... 

Most notebook computers are also able to use AC power with a special adapter that converts AC power into DC power (called an AC adapter). These can be integrated into the notebook (as on some Compaq notebooks) or as a separate brick with a cord that plugs into the back of the laptop. 

One unique situation crops up if you have a Compaq Deskpro. These computers have twists before each of the drives and the drives are reversed. The first drive on the cable, for Deskpros, is the A drive, and the second drive is the B . Finally, Deskpros will sometimes have a tape drive connected to the last connector on the cable, after the B drive and on the same cable. This tape drive must be one specially made for a Deskpro. 

IDE was such a popular hard disk interface that some people have adapted CD-ROM and tape devices to operate on IDE-type interfaces as well. Granted, it should be noted that an "IDE" CD-ROM may or may not coexist peacefully with an IDE hard disk. The former may reduce the performance of the latter. Some of the new Compaq computers, for example, have included a second IDE bus for the CD-ROM (it is labeled specifically for that purpose). 

Which kind of device is connected to the last connector on a Compaq Deskpro ... 

D. Occasionally you will find a Compaq Deskpro with a tape device attached. It will be attached as the last drive of the chain. 

Many desktop computers (such as Compaqs, IBM PS/2s, and Hewlett-Pack-ards) use a special drive carrier that holds the drive in place and can be easily removed without tools, thus eliminating the need for special rails. With most drives, however, you can just remove the mounting screws and slide the drive out. Consult the computer s documentation to see exactly how to remove your specific type of drive. 

A+ certification is recognized by most major computer hardware vendors, including (but not limited to) IBM, Hewlett-Packard, Apple, and Compaq. Some of these vendors will apply A+ certification toward prerequisites in their own respective certification programs. For example, an A+ certified technician is automatically given credit towards HP laser printer certification without having to take prerequisite classes and tests. This has the side benefit of reducing training costs for employers. 

The PERVAP simulator (tubular module) was developed by Alvarez (2005), using FORTRAN language (Compaq Visual Fortran Professional Edition 6.6.a). The mathematical model applied is based on the solution-diffusion mechanism. Activity coefficients of the components in the feed phase (jj) were determined using the UNIFAC method (Magnussen et al, 1981). The prediction of diffusion coefficient (Z) ) was carried out using the free-volume theory. 

In large-scale systems IBM and Fujitsu led the way with revenues each of 5 billion, followed by NBC with 4 billion, and Hitachi with 2 billion. In servers IBM again was first with 7.5 billion, followed by Hewlett-Packard and Compaq, each with 4 billion. Then came NBC and Toshiba at 2.5 billion, with Hitachi and Bujitsu at 1 billion. 

In desktops and software the Japanese Big Bour were also challenging the U.S. companies. In desktops, IBM had revenues of 13 billion, followed by Compaq with 11 billion, then came Fujitsu with 10 billion, Toshiba with 8 billion, and NBC (which had acquired Packard Bell) with 7.5 billion. Next came Dell also with 7.5 billion. Apple and Hewlett-Packard had 6.5 billion and Gateway 5 billion.
