The venerable PC bus which connects the CPU to the rest of its parts has been a major drag on systems ever since processors broke the 1GHz barrier [in contrast, Apple, with its G5 systems, was able to implement a new 1GHz bus from the get-go, greatly enhancing system throughput as a result]. The difficult nature of bus standardization has meant that developments in this area tend to be slow and somewhat tectonic. The article reviews expectations for major changes in PC bus architecture within the next 18 months.
Itel is rolling out its PCI Express architecture, which uses a mesh/fabric concept to allow point-to-point serial connections among multiple devices. While this will push bus speeds up to a 2Gb/s bandwidth, it will be completely incompatible with the older PCI architecture, despite its name. Trusted processing is being built into the 'LaGrange' CPU to increase security, and additional security chips are being implemented to guard the periphery. The upshot of this is that trusted systems will not be completely interoperable with nontrusted systems.
As the article points out, this has major implication for PC acquisitions, especially for organizations large enough to have an acquisition cycle. When one adds the hardeware appetites of Microsoft's 'Longhorn', it appears that standing pat on technology is one option IT executives do not have. There are numerous snakes in the weeds here, not least the potential of these developments to create a two-tier computing community exacerbating divisions between haves and have-nots.

Careers that involve work with computers increase daily.Computers are an important part of business, industry and other parts of the economy.
Computer careers involve operating computers, maintaining the software and hardware of microcomputers, and networking computers so that they can communicate with one another.Students may choose from diploma, AOS, or AAS degree programs in applied computer technology and the AS (transfer) program. Students in the applied computer technology program receive a foundation in computer hardware, networking, and computer applications. They also have the option of choosing to concentrate in one of two areas: computer support or industrial computer electronics.
