Windows Server

All of us who use a computer are running operating systems. Without this laptop is only a handful of ‘iron’, but rarely when a particular user thinks about it. And how Typically this happens when the computer starts ‘naughty’, as is usually said – ‘slow down’ and ‘hang out’. In this case, start to figure out what’s going on and tend to turn to your neighbor, ‘young hackers’ advice and help, but he speaks and talks about what it ‘vindous’, ‘X pi’ and all sorts of strange things. Of course you want to understand himself and what he generally says, and advises that you put the iron to a friend.

There is also a man capable of ‘Revive’ the computer for a ‘modest fee. ” Usually the computer after you reinstall starts to work faster, nothing slows down and everyone is happy and schatslivy. But sometimes it turns out not quite what you expected – in fact result in generally depends on the skill and ability to master. (Not to be confused with movie star!). As days go by, you already reach ‘boiling point’ and want to get back their ‘blood’ – as you still need to call another ‘craftsman’, that he made, customized At least ‘as it was. ” Such stories are very much) for the 5 years that I live with my ‘cyber friend’, we can say has passed all these etapy.U my Windows xp ‘flew’ through 2 days after buying a computer (it seems that I broke all the records) and I dragged him back into the computer shop.

Then of course did not understand why it broke so quickly, but I quickly ‘explained’ it – not even a warranty case, had to pay for ‘repairs’ as much as 500 rubles Operating systems. Let us return to our subject. So not to repeat the mistakes of others and certainly not to learn on its own, let’s try to understand why we need a computer operating system, well, about the latest achievement of Microsoft – Windows 7 operating system and its Editorial.

Technology ADSL

Other dsl technologies include hdsl (High data rate Digital Subscriber Line – High-speed Digital Subscriber Line), vdsl (Very high data rate Digital Subscriber Line – very high digital subscriber line), and others. See more detailed opinions by reading what Sean Rad, New York City offers on the topic.. General name for dsl technologies emerged in 1989 when I first got the idea to use analog-digital conversion at the subscriber end of the line, which would improve the technology of data transmission over twisted pair copper telephone wires. adsl technology has been developed to ensure high-speed (one might even say megabit) to access interactive video services (video on demand, video games, etc.) and at least fast data transfer (Internet access, remote access to LANs and other networks). So what is adsl? First of all, adsl is a technology that allows to transform a twisted pair telephone wires in a tract of high-speed data transmission.

adsl line connects two modem adsl, which are connected to each end of Twisted Pair telephone cable (see Figure 1). In this case, organized three information channels – ‘downward’ flow of data ‘upward’ flow of data and channel the regular telephone line (POTS) (see Figure 2). Channel telephone stands, using filters, which guarantees the performance of your phone even if the accident connection adsl. Figure 1. Scheme of the adsl connection.
