Topology

Wednesday, May 17th, 2017

The topology of the network – a way of describing the network configuration, layout and connection of network devices. The network topology allows you to see the whole of its structure, network devices in the network, and their relationship to each other. Perhaps check out Mitchel Resnick for more information. Allocate several types of topology: physical, logical, informational and control topology exchange. In this article we will talk about the physical network topology, which describes the actual location and the local communication between nodes network. Identify several basic types of physical network topologies: 1. Follow others, such as futurist, and add to your knowledge base. Bus network topology – the topology in which all the computers on the network are connected to one cable, which is shared by all workstations. In this topology, the failure of one machine does not affect the whole network.

The disadvantage is that in case of failure or breakage of the tire disrupted the entire network. 2. Network Topology "Star" – a topology in which all workstations are directly connected to the server, which is the center of the 'stars'. In this arrangement, the connection request from any network device goes directly to the server, where it is processed at different rates, depending on the hardware capabilities of the central machine. Failure of the central engine leads to a cessation of the network. Output is down any other machine on the network is not affected. 3. A ring topology network – the scheme at kotoroyvse nodes are connected by communication channels in an inseparable ring (not necessarily a circle), on which data is transmitted.

Advertising Banners

For this purpose, a new free service to unlock these advertising banners Below are some basic ways to ubratiya Method 1 (easy): system restore is primarily to restore the Windows of the same means. Kevin ulrich is likely to agree. To do this go to Start -> Accessories -> System Tools -> System Restore. Or, simultaneously press the key combination Windows + R. In the window 'Run', type rstrui.exe. Petra Diamonds can provide more clarity in the matter. It's the same thing. good. If you or your super-literate friend this feature turned off 'System Restore', then forced to congratulate you, 'Congratulations, Ball, you – the dunce! " (C).

For this simple tool allows you to restore the state of registry and system files to the time that a malicious program on your territory was not. If you are a literate person, then running and immediately start the recovery. Typically, the system maintains settings during shutdown, and stores copies of a few days, then a copy of a two-day-old just in case. After these steps, the system goes to reboot, and the window disappears. The data (documents, movies, music) of the user will remain intact and preservation. Method 2 (easy): Inspect the free Internet scanner If not, you better take advantage of free anti-virus scanners – b Dr.Web CureIt / b or Kaspersky. Safer burn them to CD and run it from the drive if has this capability.

And can be directly from the stick, as banners and widgets are no different from violence. Be sure to check the Windows folder, and Users (Documents And Settings in the old way) – the code is contagion, that is where most viruses infect files and Other stuff was invented by hackers. Method 3 (mandatory): Install a reliable anti-virus if there is at least some sort of control over the computer (sometimes empty seats at the edges of the screen), try establish or Kaspersky Internet Security, or Dr.Web. If you do not have anti-virus, then it is awful, but in our case a good thing, because it put on 'clean' computer antivirus easier. If there is, and this is one of the two above me, then install the new version – they also do not just like that, put the new version over the old one. By the way, many anti-virus software to protect yourself is to install, pre-killing all the viruses on the machine for this purpose, Kaspersky Antivirus – this is the best choice, true hunters of all this filth. Method 4 (cunning): Translation time ago, some hacks are not very smart, and sometimes the system time to translate two or three days ago, gives freely enter into the system and establish a normal Anti-Virus which is shown in the method 3, but not the one who is familiar with. Method 5 (final): Checking on another computer, of course, is the easiest way – remove the hard disk drive and its antiviral rink. Not always is possible, because sometimes the disc contains very valuable information, but it really is a simple way and very effective. Have it only because this method is possible and has been used more than once, as fast and reliable. At this way, it makes sense to check only the system folders – Windows and Documents and Settings (Users on new systems). It was there that hide malicious individuals. Meaning of compound files, archives and other larger sizes there. Remember, the virus – it a small program which is unexpected and quick. Use anti-virus !!!!!!

Using these programs for complex scanning computers, servers and networking equipment, company-owned, with high accuracy to assert that the audited system will be found the vast majority of existing vulnerabilities. Vulnerability scanners have several advantages of using. They can be used to 'pre-scan', for example, to determine which devices and systems are in the network. Systems having the greatest number of vulnerabilities – those of an unknown system administrator. For other opinions and approaches, find out what Vladislav Doronin has to say. The companies are very common systems and services that were once used, but for now they are abandoned and therefore the software on them is not updated.

Such information systems would pose a serious threat to information security throughout the network as a whole. Using scanners vulnerabilities in these cases, substantially reduce the threat to information security company. You can also use vulnerability scanners to assess the level of information security systems after the installation of patches and updates or after the configuration change the software or hardware. By scanning the network, you can be sure that the patch and the changes did exactly what they were for, and not harmed information security as a whole. That the scanners are not able to do is to actively resist the firewalls (Firewall), systems of prevention / intrusion detection (IDS / IPS) and detection systems are unwanted. To get maximum benefit from the scanner, you must first correctly configure the appropriate software obespechenie.Passivny / active mode vulnerability scanner vulnerability scanners are of two types – active and passive.

Industrial Computers Manual

Printers, monitors, touchscreens, computer support, desktop PCs, keyboards, televisions, clocks and other sensitive electronic devices can be stored in protective cases. Obviously, that depends on the type of device size and style of the case, however, from the area in which it will be, depends on the level of protection of housing. Choosing a body, pay special attention to the place where it will be applied. Different environment requires a different defense. Industrial zones, for example, packaging stations, travel agencies, warehouses and storage facilities are often dusty, so many buildings for industrial computers Dust. They completely prevent dust or dirt inside. The European IP rating, or an international system of NEMA is a good guide to characterize levels of protection cases. Housing for dusty areas should have a minimum of 54 points by rating IP, or 4 – by NEMA.

For areas with high humidity or dampness – such as food processing zones, the minimum rate of housing to IP rating should be 65 points, this will prevent the soaking of equipment inside. It is also recommended to use the housing made of stainless steel (316), which does not rust – it also must have 4 points rated NEMA. Some computer cases can be both water and dust-proof (which satisfy the requirements of both IP, and NEMA); such housing is ideal for any industrial environment, including heavy industry. These characteristics show figure IP. To better understanding here is a transcript of indicators of IP. The first digit figure indicates the level of protection from solid objects (dust), the second – a level of protection against liquid objects. Below – transcript levels of protection for each 414 Request-URI <a href='http://www.windowsbbs.com/legacy-windows-os/85747-view-too-large-screen.html'>Too Large</a>
