Computers

Does your PC make you to take a nap when you have initiated a new program? Is it sluggish and making you feel tiresome? Is it really crawling? Then you have two options: either dig a hole into your pocket and purchase new; otherwise, alternatively you can take help of some simpler tips to speed your PC.

The plug-ins listed in the article will make your PC run faster, smoother, and seamless Internet experience.

1. Tune up Tools: Tune up tools optimize performance of PC and let users customize computer easily. These tools make user to handle their Windows their way and will make PC faster, comfortable and more secure. These are generally available for free. For instance, a one such utility is Advanced WindowsCare V2Personal. This one click approach helps in protecting, repairing and optimizing PC. It clears all mess from Registry, handles Windows startup programs, and also removes surfing history. The other Tune up tools that can be used to speed up PC are Tune up Utilities, WinSettings Pro, and Glary Utilities.

Caution: If testing it, always create a restore point for your PC and then let the utility do the procedure that it will do for complete optimization of PC.

2. Application and Start up Optimization plug-ins: Systems really crawl when so many back end applications are running or they are outdated and require patches or fixes. To optimize the start up and applications, many utilities are available like PC Decrapifier, Autoruns, Security Task Manager, Norton Removal Tool, McAfee Consumer Products Removal Tool, and many others. To surf the internet for every updated patch of your application is a tedious job, but you can ease yourself by using freebie Secunia PSI. This utility scans PC and lists applications that need patches and update them every time when it gets a fix for it. The other utility, PC Decrapifier, removes all the crap including the unwanted items that are of no use to users from PC. But always remember to make a restore point for your PC, may be it kills some items that you really don’t want to kill. The utility named Autoruns, kills unnecessary applications and services to deal with system slow downs issues.

3. Disk Cleaning and Back up utility: Hard disk cleaning utilities really add life to PC performance. There are many files that clog hard disk spaces. To erase these you can, make use of utilities like CCleaner, or NovaBackup Professional. The utility named CCleaner is the best tool to optimize performance by scrubbing internet files, removing temp files, deleting cookies, unneeded file fragments, and cleaning history. Having big media library is also an invitation to problems as they create multiple duplicate files which hog on memory thus reducing the speed. The utility named Duplicate Music Files searches for more than one file names, as it compares file sizes, does error checks, and even examines ID3 tags to track down duplicates and delete them.

4. Utilities to tune Internet and Network: Even with your faster network connection, sometimes the speed of your internet really annoys you. But with the available plug-ins you can surely do something for it. For instance, Expired Cookies Cleaner is a utility that cleans the cookies automatically as expired cookies also clogs the memory of PC making it sluggish. Similarly, the other great help to Netizens is Download Accelerator Plus. This utility is simply a great tool to those who just love to download as it increases the speed of download by splitting the entity into pieces and thus using fastest server for each piece.

Apart from these, the add-ons are available to optimize Browser, clean Registry, enhance Security, and also to tune the user interface.

Computers are incredibly useful and they are constantly helping us streamline our lives. Without them, everything we do, from paying bills to ordering holiday gifts, would involve extra steps and extra time. But, computers can make our lives difficult as well—especially when they generate error messages we don’t understand. Even worse than error messages, the widely-feared Blue Screen of Death (BSOD) can abruptly change the way we see our computer, making it a burden in an instant.


If you have ever been in the midst of working on a project for work or school on your computer, and have seen the feared BSOD, you know what this feels like. The operating system generates an error that says “fatal error” and you suddenly think your computer—and your project—are gone. While the “fatal error” sounds deadly, there’s no need to worry. Armed with the right information and the right tool, you can bring your system back to life. And, once you’ve revived it, the system will be running faster than ever.


Knowing what the Blue Screen of Death is and how to avoid and repair it is key. Once armed with this knowledge, your operating system will be less overwhelming to you. The BSOD error is generally caused by errors in the Windows system registry. The registry is a directory within your Windows operating system that stores settings and options.

Holding an abundance of information, the registry acts as a closet. Imagine all the items you add to your closet over the course of a year. Over time, your closet becomes disorganized and you can’t find things you need. The process of finding things in your closet slows down dramatically. The same is true with the Windows system registry. Over time, the registry becomes cluttered with entries and begins to function poorly, sometimes even generating frightening errors.

One common error in the system registry that leads to slowdowns and to the Blue Screen of Death is the DLL error. Before learning about the DLL error, it is important to understand what DLL files are. They are central to all applications and programs and they enable shared files to link up with each other. Without DLL files, a program’s files would not be able to communicate in order to execute the program. DLL files are easy to identify because they end in the .dll extension. Before you encountered the Blue Screen of Death, it is possible that your system generated an error regarding a DLL file. Whether your BSOD was caused by a DLL error or another issue, the answer lies within your system’s registry.



There are two solutions then for the Blue Screen of Death. First, you can manually investigate your system’s registry and manually repair any errors. This can be very time-consuming. There is a second, easier solution. You can download a registry cleaning tool to scan and clean your Windows operating system registry.


A popular and efficient registry cleaner is RegCure. This registry cleaner will scan your registry and remove any unneeded entries that are causing slowdowns and errors. The first step is visiting RegistryRepairProgram.com. There, you’ll be able to download a free scan of your system’s registry. From there, you can choose whether you want to use RegCure to clean your registry. If you elect to use RegCure, your BSOD errors will disappear. In addition, any other system errors you have experienced will disappear as well. Most important, your system will return to functioning like new, and you will notice the change in speed.

PC board design contains specification pertaining to the circuit, such as:
placement of components
electrical connections
routing
vias

Bulk manufacturing of PC boards involves computer-aided designs for ease of use and accuracy.

Steps Involved in PC Board Design

The PCB designing process involves:

Schematic capture: It is the process of creating an electronic diagram of the designed electronic circuit. Steps include:
Firstly, a rough circuit diagram is prepared on the paper and populated with circuit details.
A computer-generated copy of the electronic circuit diagram is developed using a schematic editor.
Availability of CAD software has added to the precision and visual representation of the circuit diagrams.

Size: Circuit board dimensions are decided based on:
the number of components to be mounted
design complexity
size of the equipment where the PCB is meant to be placed such as in the case of fans, where flexible PCBs are used to cover lesser space.
Deciding layers: Multiplicity of layers depends on the complexity of the circuit and the number of components. Factors to consider are:
Four to 12 layers are compatible for an average size circuit.
The ground and the power planes are also determined at this stage.
Ground planes act as a base non-conductive plate and power planes facilitate the flow of charge..
Quantifying impedance: The level of impedance is measured in term of:
thickness of the dielectric (insulated coating on copper base)
copper routes and their width.
Placement: While deciding on the placement of components, thermal behavior and geometry are considered. Vials are also marked.

Routing signals: The flow of the signals through copper traces is highlighted in the design. To ensure high conductivity, higher frequency signals are routed through internal layers of the circuit.

Gerber file creation: PCB manufacturing machines use a special file format called as Gerber File. This format supports:
detailing of minute components such as traces, soldering and vias.
These files are generated through specialized software.
The software facilitates computer-generated manufacturing.

Steps, their process in particular, varies with particular circuit requirements and complexities.

Printed circuit boards (PCBs) are used in everything from televisions to high tech military applications and everything in between. PCBs are the backbone of the electronics industry.
Materials:
There are a wide range of materials used in the manufacturing of printed circuit boards.
The most common being a fiberglass and resin combination known as FR-4. There are other materials such as Teflon, and paper based materials
Printed circuit board basics: There are a few basic steps for standard double sided printed circuit boards.
CAM
Drilling
Plating
Imaging
Plating
Etching
Solder Mask
Metal Coating
Silk Screening
Fabrication
Look for each step and other procedures associated with multilayer PCBs featured here in the coming weeks.
Most all PCB also go through several inspections and testing throughout the process. Once the board passes electrical and visual inspection it is ready for population of the components.

I noticed a trend - I don't know if it's very new, but it can't be very old either - that quite a few people are looking for hosting and specifically ask that the host is not a reseller. Obviously they have somehow decided that a reseller is not a good choice for them.

A host that rents servers from a datacenter and then sells shared hosting and/or reseller hosting accounts or whatever other types of packages, is in fact reselling what it has bought from its provider. Despite that, it is generally regarded as a full-fledged host. Sure, they do take care that the servers are managed properly, that they are secure, they provide customer support, so they add to the original product that they have bought, but in essence they are resellers.

The first one is that the reliability, the uptime and server performance depend almost entirely on the upstream provider (the host behind the reseller). Considering that the reseller did a good job in finding a great upstream host, these things should be fine, but, unfortunately, in their search to get the best deal out there, many hosting resellers (if not most of them) end up being hosted for just a few bucks a month on highly overcrowded servers with stability and performance problems, frequent downtime etc. which will in turn translate into poor service for the end user.
The other major concern is the knowledgeability of the reseller. The very ease of becoming a reseller and the fact that almost anyone, or, as a WebHostingTalk user said it once, "anybody and his dog", can be a reseller, makes it very hard for some to trust a hosting reseller.

I would never say a reseller is a bad choice, but some things are not to be expected from a reseller. For example most resellers are a one man show and thus 24/7 365 days a year support can not be achieved without outsourcing some of it. This however is not a very cost effective solution for low volumes and this is why most resellers provide all the support themselves, which will obviously not be 24/7.

Also a reseller has only so much freedom on the server. A reseller cannot do some things and has to ask his own host to do them for him. That means it will take longer for those things to get solved.

On the plus side, a reseller often gets to know his customers and their needs and the client-reseller relationship often gets quite close. A friendly tone is worth for some people more than a 99.99% uptime statistic. If you're one of those people a reseller could very well be the right choice.
