I love the heat at the beginning of the year!
Finally, winter has come. The time has come when it is necessary to seriously think about cooling computers. In magazines, the topic of computer cooling is raised, as a rule,…

Briefly about the main thing
So, without maintaining a normal thermal regime in the case, we will not see good luck! To cool the air inside the case, any computer has at least one fan.…

“Think for yourself, decide for yourself …”

Until now, we have considered solutions that save money when organizing the LAN of a small office due to some compromises with standards. There is another way of organizing the office cable system, not designed to save money by the methods discussed above, but rather, assuming some of their redundancy at the initial stage, but giving savings later.

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

“Divide and rule”

As a horizontal cable in modern SCS, a four-pair balanced cable is used mainly. It is known that for signal transmission in Ethernet and Fast Ethernet networks, only two out of four pairs are used. The remaining pairs are virtually idle. The technical characteristics of modern cables in terms of the NEXT parameter are very high (see Fig. 1), which allows the use of free pairs for transmitting analog and digital signals without any noticeable effect on the operation of the main application.

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 subsystem SCS the presence of floor cross. Horizontal cables diverge from floor crossings to workplace outlets. Recently, in almost all newly installed office networks, Fast Ethernet 100Base TX technology has been used, which places high demands on the parameters of the cable system. 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 victory of the losers, or the story of the creation of FLASH memory (part4)
Our main goal was not to change anything during the production process, and to solve the problem of how to place electrons on a floating shutter. Initially, we abandoned the…

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…
