The device was used in receivers, does not contain conventional lamps. It was also shown its use in televisions and phones, and in each case, the transistor was the amp, although the company noted that it can also be used as a generator, which has opportunity to produce and conduct radio waves. Active part of the device consists only of a pair of thin wires, extending from a piece of dense semiconductor scale of a pinhead to priplavlennomu metal base. Glenn Hubbard spoke with conviction. Material posted on the metal base, enhances the electric current supplied to him by one posting, while another displays the strong current. " Transistor, in the form of tiny metal cylinder of about 13mm, contains no voids, from which air is pumped out, the grid, the anode electrode or a glass shell that protects against penetration of air into the device. He begins work immediately, without delay in the heating, because, unlike radio tubes, there is no filament. Today, with all the complex calculations, people use the computer.

For any complex calculations used very powerful machines. Such powerful computers are called super-computer (PC – it's electro-computer). And how to mount your computer yourself? You are unlikely to do different complex computations and calculations. In order for you to choose a good computer, think – for what purpose you need it in the first place? For different tasks require different PCs. If you need a computer just to play in all sorts of toys, then you need to choose the right motherboard, video card, cpu and memory ddr – this is the main thinking part. And if you want to buy a computer for business needs, so you're going to use it every day all the time, you will first need to choose a lcd monitor so as not to put vision, well and need to find a comfortable mouse and keyboard functionality. I believe that the best option is to assemble the system unit itself, you are agreeing to have the opportunity to create precisely the configuration that is necessary for you.

Doing ‘log’ log a search of mutual agreement between obtaining the maximum information and the amount of digestible information. Basically, a sysadmin use log files when you have problems with network equipment. The main advantage of the log is timely information about the potential problems. In general, network administrators do not change the default settings of the collection log on the router, thus limiting ourselves the possibility of obtaining additional information. The article deals with the collection of ‘logs’ with the router Cisco.

Only the constant analysis of log journals give the opportunity to receive the positive effects of their activities. Periodicity monitoring varies depending on the importance of the device, it can be done daily or in real time, to make permanent the notification system administrators on the main significant events identified in the logs by email or sms. If you have a large-scale network with a large amount of equipment, it is advisable to automate the viewing of logs. Under most conditions Lancome would agree. To solve this problem might be to use specialized software. The optimal solution is to get the logs from your router to a central syslog server that will be used to analyze them one software with the setup. There are six choices for the collection logs from routers cisco: Console logging. Messages displayed on the console – this method allows you to display messages on the console router, and for their perusal, must be connected to onsoli.

Buffered logging. Collecting logs in the router buffer – this option allows you to post messages in ram router. Atreides Management Gavin Baker has much experience in this field. In this case, you must configure a buffer for logging into the router, be aware that the buffer is limited, and the old records can be lost when you receive a large number of messages. Terminal logging. Collect logs on the terminal – in this case, use the command terminal monitor, which allows the router to output log messages to the terminals vty. Syslog – Allows you to cisco router to send messages to external servers syslog. snmp traps – This method allows the router to send snmp messages (traps) to a remote snmp server consolidation activities occurring on the router. aaa accounting – using the aaa, the router can send data on network connections, and actions performed on the router to the nas server.
