What is Network Management Software?

Networks often need to be managed from time to time to ensure efficiency. Network management software’s role is to monitor user’s computers within specific networks.  The software also manages the network along with all its elements such as business applications, WAN links and mail servers.  Other elements that network management software can manage and monitor are a user’s entire LAN infrastructure which consists of things like nonstandard devices, wireless routers, switches, printers and load balancers.

The software can do this at the same time it ensures that a user’s networks and systems are operating efficiently.  The Network management software is indispensable to some users.  Among these users are large businesses and companies, small companies who depend on computers to do their work.

The companies, especially those with many computers need the software to help them in their monitoring which ultimately brings maximum efficiency and performance. There are different network management systems available for users.  Network and system monitoring is one form in which the software comes.  This particular software comes with tools which can be used for commercial network and enhanced system monitoring.

The center for networks operations uses the software to manage servers as well as networks. Application monitoring is another form in which the network management software comes. This software functions by monitoring different applications behavior and performance and by focusing on particular databases and e mail systems as well. Enterprise management also features among the types of network management software available for users.

The software was designed especially for small business as well as commercial use. With it come integrated management for networks and also system management.  Moreover, Enterprise management has functions such as application and database management which are very essential to a user. The Security monitoring software is another form of this software and its main role is to audit and protect threats that come up in a user’s network.
Device monitoring is another type that users should have and functions by recording the devices activities as well as those of the servers that are at work in the network.  Finally, there is the Network traffic analysis and performance monitoring type which functions by overseeing the flow of traffic between as well as through vital devices in the network.

It also monitors network traffic performance and statistics utilization. This is to ensure that one analyses the performance of the network efficiently, thus enabling one to keep monitoring the network traffic flow.

 

What Are The Computer Parts?

 

The motherboard comprises the main circuit board found in computers. It contains the CPU, circuitry and RAM modules. Adapter cards are plugged into the motherboard and hard drive into the IDE headers.  The CPU is the most valuable chip on the entire system and it serves as the brain.  It carries out commands and the faster it is the better. Its processor produces a lot of heat so heat sinks and fans protect it from overheating. The memory is a program or set of data that holds information temporarily for the processor.  Hard drives store all programs and information found in a computer. Monitors are measured diagonally and display the work being carried out on the computer.

To input information a keyboard is required and it has 103 keys. The video card is used to send visual output that a program produces onto the monitor to display on the screen. For maximum performance the PCI-Express slot is used. DVD and CD drives are used by the computer to read and burn CDs and DVDs. They have high access rate to locate particular files. RAM and flash cards are parts found in the memory section.  The case is the outer metal box that the other parts of the computer are fitted into.  It is for the protection of the computer parts inside.

The large cases leave space for expansion and inclusion of extra hard drives and R/W drives. There are three types of cases; pizza box case which is thin and found in network stations for office or schools. The desktop case sits horizontally on the table and has room for cards. The tower case is the most commonly used as it comes with plenty of room to include extra drives. Power supplies, deliver power to all computer parts.

Enough power should be supplied to the components but, higher end parts receive more power.  Power supply needs to have the same voltage as other power outlets in the house or office. When a computer is running it uses the cooling system to remain cool.

 Case fans can be used or liquid cooling which is more efficient than fans because it uses water and antifreeze.  Components like the CPU get damaged when they overheat and needs to be cooled down because high end video card and processors heat it up when used. The average temperature in the computer should be maintained at 70-90 Celsius.

Public DNS servers offer public service.  They are servers that are provided by a company known as Granite Canyon Group, LLC. The service is offered to any user that needs it whether primary or secondary DNS without any charge.
This service maintains the UPS, which is protected by FreeBSD servers that are used to satisfy any DNS queries.
Public DNS serves several purposes and is useful to the user in various ways.
When inside a firewall and there is need to access public name servers that are outside the firewall, when in need of names servers, which are closer to ideal internet backbones such as those for North America and when in need of secondary DNS servers.
Users that are not able to acquire free services from an ISP and do not want to do it themselves, benefit from public DNS servers.
Most of these DNS servers are privately owned, which means they offer their services to only those people that own and configure them.
Public DNS servers on the other hand freely serve anyone in need. Their basic function involves translating hostnames into IP addresses.

 

They are easily available on the net and provide users with the needed response. People prefer to use public DNS servers so as to speed up their personal internet browsing. If a person looks at their IP configuration address they will find their current IP address DNS server and can easily change their IP to an IP address that suits their needs.

Users need to be careful about public DNS servers since some have been found to be vulnerable to Kaminski flaw.  This flaw allows various hackers to succeed in sabotaging DNS servers.

Once they do this they then send web visitors and users to various sites, which have been set up with the intention of hacking into the users systems. Some users prefer fast DNS servers but unfortunately, public DNS servers are not as fast as most users would prefer them to be.

One major reason for their being slow is that they are slow in direct proportion to how far they are located from the user.  Increase in speed can only be possible with privately owned DNS servers that have forwarders to the users ISPs servers.
