Chapter 7: Managing your network with network monitoring tools

When it comes to managing a network, the user would ideally have to consider several connecting issues and this would include methods, processes, procedures and toll that would ideally assist in maintaining and provisioning the system in place.

Elements such as operation deals with keeping the network functioning smoothly and efficiently would require the monitoring of the network to spot problems before they create dire consequences and address them accordingly.

The administration deals with keeping a firm hold on the resources within the network and how the assignment processes are decided would ensure the network is kept under control and manageable.

The issues of maintenance is also another common concern with the need to perform repairs and upgrades being the main focus most of the time. This could take on many forms and there should ideally be a good support system in place to ensure these are done in an efficient and quick manner.

The support for the network to be able to provide optimal service platforms is also something that is important enough to be a concern for the user. Provisioning elements are concerned with configuration of resources within the network as the support given would have to include the setting up of the network to ensure new customers are kept in the loop always.

The FCAPS also depicted to represent fault, configuration, accounting, performance and security are all functions that are performed as part of the network management coordination. This exercise would entails other works such as controlling, planning, allocating, deploying, coordinating and monitoring of the resources that pass through the network simultaneously as any given time.

Data management is often collected through several mechanism where there are agents installed within the infrastructure, synthetic monitoring that simulate transactions, log activity and real user monitoring.

Chapter 8: Computer network maintenance and repair

Computer network maintenance and repair are elements that should ideally be factored in very early on within the exercise of acquiring any system to be used by the individual or business entity.

Today computer networks often function as the primary communicating, research and sourcing for information tool, thus it needs the attention of good maintenance and repair allocations, to ensure this is not disrupted in any way for longer than necessary.

This maintenance would include issues such as security measure within the networks. Competitors are often engaged in accessing delicate information that can be used against businesses for their own obvious gain and this is quite prevalent online. Identity theft is fairly common as hackers usually make a living by extending such services to interested parties, thus the need to step up the maintenance and repair levels to ensure consistent monitoring of this.

The general malfunctioning of the system being used can cause a lot of damage to the user’s business or personal usage, thus the need to have some recourse action plans in place.

The following are some areas that could be monitored to minimalize any unwanted hiccups in the system being used:

The user should make it a habit to block any unwanted junk form getting to the network in use, with tools such as Gateway

Appliance. In place within the system and the incoming information, this tool is able to control the number of unwanted material form getting into the system.

Ensuring the antivirus system is use is always kept current and updated is important. There are a lot of choices which include AVAST and AVG which are relatively cheap to acquire. Generally the user should be keen to avoid any form of problems that could contribute to the need to acquire the sendees of a computer network repair team.

Chapter 9: Troubleshooting computer network

There are many possible reasons when a computer is unable to connect to a network or see other computers on the network. Understanding some of the possible reasons will allow the user to conduct some troubleshooting exercises to try and rectify the situation.

Some of the reasons that can be handled by the right troubleshooting measures would include the network card not being connected properly, bad network card drivers or software settings, firewall preventing computers from seeing other computers on the same network and also connections related to users and bad network hardware.

Accompanying these are some possible solutions that can be addressed using the troubleshooting exercise mainly due to the fact that a large variety of network configurations, operation systems, setups and other connecting services may not always be something to do with the network operating system in current use.

The user should ideally be able to be connected to a company or large network to facilitate administration of the said network and resolving such issues would require some recommendations done through the troubleshooting exercise.

Some of these troubleshooting exercises would include the verifying of connections and LEDs where the network cable is checked to ensure it is properly connected to the back of the computer. In addition to this there would also be a need to ensure the LEDs on the network is properly illuminated in solid green.

Adapter resources are also something to look into through the troubleshooting exercise when a new network card is being installed into the computer system.

The card’s resources should be properly set and should not be conflicting with any hardware in the computer. Adapter functionality is also an exercise to conduct where the network card should be capable of pinging or seeing itself by using the ping command.
