The victory of the losers, or the story of the creation of FLASH memory (part2)
This type of memory was made in the form of a two-dimensional matrix of conductors, at the intersection of which a thin jumper (20-30 μm) was created from metal or…

Comparison of motherboards supporting the new memory standard PC2100 (DDR266)

AMD processors have long gained popularity among computer users due to their high performance at low cost. Therefore, it is understandable that new motherboards for AMD processors will appear on the market with support for the 133 MHz system bus frequency (the equivalent frequency is 266 MHz) and with DDR SDRAM PC2100 memory support. So far, only the AMD-760 chipset provides this capability. Continue reading

How to avoid network downtime?

Since then, no surprises have occurred with Novell products to solve the high availability of network resources. Naturally, Novell ceased to support its once-very popular NetWare 3.x product, since over the nearly ten-year history of its existence in the world of information technology, much has flowed. The high availability solutions we reviewed, such as SFT III and NHAS, were not developed in future versions of the operating system. Continue reading

Metrology notes

Despite the variety of generally accepted tests, recently their results have often added confusion than to clarify the essence of the phenomena.

There are tests that allow you to measure the performance of a computer subsystem, for example, the speed of data exchange between a processor and memory or cache. These tests are necessary in order to find out the impact of individual technical solutions, more precisely, to understand why a particular processor is better or worse than others. But the practical sense in these tests is quite small. Continue reading

We get rid of "unnecessary" equipment
The cable system of small offices, as a rule, has only a horizontal subsystem SCS, since the office itself is usually located on one floor. Standards provide for the horizontal…
