ISO Network Management Model

ISO Network Management Model

The ISO Network Management Model has contributed a great deal to network standardization. Its network management model is the primary means for understanding the major functions of network management systems. This model consists of five conceptual areas.

1. Performance Management

The goal of performance management is to measure and make available various aspects of network performance so that internet work performance can be maintain at an acceptable level because of performance variables that might be provided include network throughput, user response times, and line utilization.

2. Configuration Management

The goal of configuration management is to monitor network and system configuration information so that the effects on network operation of various versions of hardware and software elements can be tracked and managed.

3. Accounting Management

The goal of accounting management is to measure network utilization parameters so that individual or group uses on the network can be regulated appropriately, such regulation minimizes network problems (because network resources can be apportioned based on resource capacities) and maximizes the fairness of network access across all users.

4. Fault Management

The goal of fault management is to detect, log, notify users of, and (to the extent possible) automatically fix network problems to keep the network running effectively, therefore, fault management is perhaps the most widely implemented of the ISO network management elements and the faults can cause downtime or unacceptable network degradation.

5. Security Management

The goal of security management is to control access to network resources according to local guidelines so that the network cannot be sabotaged (intentionally or unintentionally) and sensitive information cannot be accessed by those without appropriate authorization, for example if a security management subsystem can monitor users logging on to a network resource and can refuse access to those who enter inappropriate access codes.

Virtual Private Network (VPN)

  What is Virtual Private Network (VPN)? A virtual private network (VPN) is a secure connection between two private networks over a public network (in other words, over the Internet). All the data that flows over the VPN is encrypted. So anyone who steals packets from the VPN will find them unintelligible; only the parties on either end of the VPN are able to decrypt the packets. VPN connections are often called tunnels. Because they provide an isolated pathway from one point to another through the Internet. The only way to gain meaningful access to a VPN tunnel is at either end. Example for VPN Connections VPNs are used for There are two common uses for VPNs: To provide remote workers with secure access to your company network: To do that, you set up a VPN on the router, and then provide your remote workers with the credentials necessary to access the VPN. The remote workers can run a software VPN client on their home computers or laptops to connect to

Motherboard

What is Motherboard? Motherboard If the processor is the brain of the computer, the motherboard is the heart of the computer. The motherboard is the main circuit board inside the computer and however, all the components and peripherals are attached to it. Therefore the most of the compute features like scalability and upgradeability depend on the motherboard. Computer Motherboard Components Components of Motherboard Key Assessable Parameters of Motherboard Form factor Chipset CPU Memory Audio Ports and Slots Headers and Connectors BIOS Form factor The root mean square value ratio to the average value ratio of the alternating current is called Form Factor and it is the ratio of the root mean square value to the average value is also known as the absolute value of the waveform. Measurements of Form Factor, Form Factor Formula Where RMS is Root Mean Square Value, AV is Average Value Ir.m.s is the root main square value of current, therefore Iav are
