When your computer misbehaves, it's useful to know how to troubleshoot problems yourself. That way you won't have to run to the computer repair store for every issue that arises. There are a variety of things that could be going wrong with your computer, but you can usually track down and fix the problem on your own.
CompTIA publishes a six-step process related to the troubleshooting process. You will need to understand what they are on your A+ Exam. The six steps are:
Identify the problem. Establish a theory of probable cause. Test the theory to determine cause. Establish a plan of action to resolve the problem and implement the solution. Verify full system functionality and if applicable implement preventative measures. Document findings, actions, and outcomes.
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms. Determining the most likely cause is a process of elimination—eliminating potential causes of a problem. Finally, troubleshooting requires confirmation that the solution restores the product or process to its working state.
In general, troubleshooting is the identification or diagnosis of "trouble" in the management flow of a system caused by a failure of some kind. The problem is initially described as symptoms of malfunction, and troubleshooting is the process of determining and remedying the causes of these symptoms.
A system can be described in terms of its expected, desired or intended behavior (usually, for artificial systems, its purpose). Events or inputs to the system are expected to generate specific results or outputs. (For example, selecting the "print" option from various computer applications is intended to result in a hardcopy emerging from some specific device). Any unexpected or undesirable behavior is a symptom. Troubleshooting is the process of isolating the specific cause or causes of the symptom. Frequently the symptom is a failure of the product or process to produce any results. (Nothing was printed, for example). Corrective action can then be taken to prevent further failures of a similar kind.
The methods of forensic engineering are useful in tracing problems in products or processes, and a wide range of analytical techniques are available to determine the cause or causes of specific failures. Corrective action can then be taken to prevent further failure of a similar kind. Preventive action is possible using failure mode and effects (FMEA) and fault tree analysis (FTA) before full-scale production, and these methods can also be used for failure analysis.
Troubleshooting IT can be… tedious (understatement of the year). End users submit seemingly endless problems ranging from complaints of their Internet being “slow” to forgotten passwords to constant printer pains. What’s your plan of action for the next vague phone call, email request about tech issues, or help desk ticket from a big wig who needs his computer fixed… RIGHT NOW?
Worry not! We’ve got several problem-solving steps to follow that’ll help ease the stress of solving nearly any IT issue:

End users submit seemingly endless problems ranging from complaints of their Internet being “slow” to forgotten passwords to constant printer pains.

Worry not! We’ve got several problem-solving steps to follow that’ll help ease the stress of solving nearly any IT issue:
2) Gather more details, eliminate variables
In many instances, what was reported as a general issue (e.g., the Internet is down) is actually something very particular, such as a specific website being offline. Best way to find out? Ask those pertinent questions and then dig up more info from various sources such as:
Error messages: If the user reports one or you’re present to check for one, they can point you in the right direction as to why a failure occurred. For example, Windows blue screens of death provide a relevant error code that’ll give you a good sense of what caused a failure.
Events logs: Do they exist, and if so, what exactly do they say? In addition to error messages, logs often provide a timestamp so you can answer the question of when exactly events happened. Checking the Windows event viewer can be a first step in pointing you towards any relevant logs.
Can the user provide screenshots, video, or other supporting information that can help assist in the troubleshooting process?
Diagnostics results: Have you run system utilities to get even more information? For example: ping can help you remotely check if a server or website in question is reachable. Additionally, the Windows memory diagnostic can check for faulty memory, the resource monitor or performance monitor can check for unusually high CPU or memory usage, and a disk check can examine your hard drives for errors.
Monitoring: Do you have any 3rd party tools that can offer more clues or predict issues before they occur? A network monitoring solution like Spiceworks provides preemptive alerts and warnings about servers at risk of going down. And a network inventory application can provide vital statistics on dozens or hundreds of systems such as disk space, available memory, OS installed, and software running on the devies in question.
The event viewer helps you find logs that can point towards the source of a problem
Step 3: Reproduce the problem, develop hypothesis of root cause
Now that you’ve gathered basic background info, it’s time to get hands-on with the problem. Reproducing an issue simply means verifying you can recreate the same error the user reported. You can do this at the physical site of the problem, or through a remote desktop / remote control application. Neither of those options available? You might be able to approximate the same conditions on a similar computer.
Once you encounter the same error(s), you can more easily develop theories as to the root cause based on what you observe, then start taking steps to fix the issue. Sometimes you’ll find the culprit (and come up with the solution) pretty quickly. Other times, it’ll take longer and you may have to dig into knowledge bases, comb through old help desk tickets, or Google the problem for others who have faced the same issue.
At this phase, a deep understanding of how computers work will prove… useful. For example, in computer networking, if you understand 7 layer OSI model for networks (a problem can exist in any one of them), you have a framework for systematically working your way through the potential causes of a networking problem. For a connectivity issue, an Ethernet cable could be damaged or unplugged (Layer 1 issue), network requests might not be going through (Layer 3), or an application might not be properly coded (Layer 6).
Step 4: Attempt a fix based on findings
The evidence you’ve already gathered should have narrowed down possible root causes and positioned you to fix the issue. At this point, focused experimentation is the name of the game. You can try tweaking changing settings related to the problem, swapping out faulty parts, repairing corrupted files, updating drivers and software, etc. until you solve the problem (or at least get closer).
Still stumped? You can always restore the machine back to a point when everything was working fine. That is, if someone took the all-important step of backing up data or system state before the problem happened so you can go back to a simpler time… before problems plagued their PC.
While every issue is like a unique snowflake, a significant number of issues can be resolved through common troubleshooting steps like rebooting the problematic machine, checking for DNS and DHCP issues, checking the device manager for driver issues, cleaning up a machine, or checking firewall or proxy settings, etc. For issues that are tougher, if your own experimentation and Google searches don’t result in a satisfactory result, browsing discussions on IT forums such as Spiceworks can be extremely helpful for fixing PC issues. If nothing turns up there, you can always ask the community of millions of IT pros in Spiceworks.

VMware networks works by loading a small, efficient operating system, hypervisor directly on the host hardware. The VMware hypervisor has a small footprint and is extremely efficient, with a very small overhead. Device drivers for nearly all major brand devices are available from VMware. These are loaded during the configuration process.
The client operating systems, such as Microsoft Server 2008, Microsoft Small Busines Server, Linux varieties, etc. are then set up as virtual machines, working directly with the VMware layer rather than with the actual hardware. This allows replacement of hardware to be very simple. If the hardware is replaced, VMware is reconfigured for the new hardware, and the virtual guest operating systems see no change whatsoever and are immediately able to boot and operate.
VMware's desktop software runs on Microsoft Windows, Linux, and Mac OS X, while its enterprise software hypervisors for servers, VMware ESX and VMware ESXi, are bare-metal hypervisors that run directly on server hardware without requiring an additional underlying operating system.
VMware could be used on server also for Data Center Virtualization, for workstation purpose please have look on given link
Awide area network(WAN) is a telecommunications network that extends over a large geographical area for the primary purpose of computer networking. Wide area networks are often established with leased telecommunication circuits.
Business, as well as education and government entities use wide area networks to relay data to staff, students, clients, buyers and suppliers from various locations across the world. In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location. The Internet may be considered a WAN.
Similar types of networks are personal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are usually limited to a room, building, campus or specific metropolitan area, respectively.
The textbook definition of a WAN is a computer network spanning regions, countries, or even the world.[3] However, in terms of the application of computer networking protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different LANs, MANs and other localised computer networking architectures. This distinction stems from the fact that common LAN technologies operating at lower layers of the OSI model (such as the forms of Ethernet or Wi-Fi) are often designed for physically proximal networks, and thus cannot transmit data over tens, hundreds, or even thousands of miles or kilometres.
WANs do not just necessarily connect physically disparate LANs. A CAN, for example, may have a localized backbone of a WAN technology, which connects different LANs within a campus. This could be to facilitate higher bandwidth applications or provide better functionality for users in the CAN.
WANs are used to connect LANs and other types of networks together so that users and computers in one location can communicate with users and computers in other locations. Many WANs are built for one particular organization and are private. Others, built by Internet service providers, provide connections from an organization's LAN to the Internet. WANs are often built using leased lines. At each end of the leased line, a router connects the LAN on one side with a second router within the LAN on the other. Leased lines can be very expensive. Instead of using leased lines, WANs can also be built using less costly circuit switching or packet switching methods. Network protocols including TCP/IP deliver transport and addressing functions. Protocols including Packet over SONET/SDH, Multiprotocol Label Switching (MPLS), Asynchronous Transfer Mode (ATM) and Frame Relay are often used by service providers to deliver the links that are used in WANs. X.25 was an important early WAN protocol, and is often considered to be the "grandfather" of Frame Relay as many of the underlying protocols and functions of X.25 are still in use today (with upgrades) by Frame Relay.
Drive Test is conducted for checking coverage criteria of a cell site with RF drive test tool. The data collected by drive test tool as Log files is analyzed to evaluate various RF parameters of the network.
Drive test Log files are important to check any RF related issue.(Call drop/Low throughput and other NW issue).For example these log files are analogous to pathology reports and only an experienced doctor/pathologist can properly analyze these reports and cure the disease.
In the same way an RF optimization Engineer analyses drive test log files to identify & rectify NW issues.
DT Engineer identifies routine field optimization issues like cable swapping, missing neighbors etc. and rectify the same with the help of the customer/OMCR. Detailed log file analysis is done by RF optimization engineer by post processing tools like Actix, TEMS.
A quick learner DT Engineer can be promoted to RF optimization engineer after 1-2 years of hands on experience. Few companies recruit RF optimization engineer directly without any DT engineer experience.But no doubt a seasoned DT engineer can do this job of troubleshooting with much clarity and efficiency. for more: rf drive testing jobs
