4 Steps to Keep your Computer Safe

Modern day computers need to be constantly protected, so to speak, thanks to the existence of viruses, spam, pop-ups and so on and so forth. If left unchecked, these unwanted applications or files can hamper our system’s performance.

So, here are a few steps by which you can keep your computer safe:

#1: Anti-virus Protection

Even though most systems these days come with antivirus protection, it’s important to understand that in order to enjoy maximum benefits, one should not forget to renew the service once the term if over. Ensuring that you have antivirus software at all will ensure that you are able to keep your computer clean from common issues related to viruses and spam.

#2: Check to see if Windows Defender or Firewall is turned on

The next thing that you have to do is to find whether Windows Defender or Firewall is turned on for real-time protection. First, you’ll have to find it in the Security section and either of them isn’t available, then you can download it from Microsoft’s official site.

You can run Windows Defender for a full computer scan after which you’ll be protected from any unwanted spyware. The same goes for Windows Firewall which will protect your computer from real-time attacks. You can also use Spybot Search & Destroy to scan your computer for unwanted spyware as well.

#3: Conduct a Port Scan

You can visit grc.com and allow it to conduct a port scan to see where your system is vulnerable to hackers, and then take the necessary steps to protect your computer after that.

#4: Download the latest updates, patches and service packs from Windows

By default, most systems with Windows allow for this to take place from time to time. However, it’s a good idea to check whether the ‘automatic updates’ option is selected in order to get the latest updates, patches and service packs from Windows.

3 Steps To Determine Whether an Apple Macintosh Or PC Is Right For You?

Apple Macintosh Or PCIf you are looking for a new personal computer, a bit of research will tell you that there are PCs available using platforms based on MacOS, Windows and Linux. What makes the decision of figuring out whether any of these PCs are right for you hard is because there is very little between them

Yet a comparison between their weaknesses and strengths will help you determine which PC is right for you, and so here are a few steps to do just that:

Step #1: List out what you want to do with your computer

While basic functions such as web browsing, scheduling and management, multimedia playback and document manipulation are usually no different on these platforms, there are certain advanced features that are best on certain platforms.

For example, if you’re a gaming enthusiast, then Windows would be your choice as opposed to the other two. Content creation, the other hand, is where the Mac reigns supreme, and is considered to be perfect for artists.

Step #2: Understand the strengths of each platform

No matter what you do, don’t think that, as a whole, only one of three platforms is the best. However, there are reasons why the Apple Mac, the pre and custom-built PC exist for customers. The Apple Mac is known for great support and service as well as great looks and features while the pre-built PC offers greater compatibility. Also, custom-built systems are not only available at a better price but their performance is excellent as well.

Step #3: Understand the weaknesses of each platform

When it comes to making a comparison between the weaknesses of these platforms, usually a pre-built PC and an Apple Macintosh is priced high. As for custom-built PCs, the issue of not being user-friendly will need non-technical users to learn more about components before attempting to put a computer together.

4 Steps to Buying the Right Assembled PC

Buying the Right Assembled PCAlmost anyone knows the difference between branded and assembled PCs, where the former is built to meet general computing needs while the latter is custom-built for purposes that cannot be met by their branded counterparts.

Although, there are advantages to both types, what becomes apparent is that a lot of thought must go into buying an assembled PC.

So here are steps that can help you buy the right assembled PC:

#1: Decide whether you want a laptop or a desktop

If you’re planning to work from one location, then a desktop would be a good idea. However, if you need to move around for your work, then a laptop would work well instead. What one must keep in mind is the fact that assembled desktops are common rather than laptops.

#2: Make a list of what you might use the computer for

As mentioned earlier, an assembled computer is usually built for specific needs. So, keeping these needs in mind, you can decide whether you want an assembled or branded computer.

#3: Determine how much you can afford to spend

For the most part, assembled PCs are cheaper than branded ones as it doesn’t come with pre-loaded software. However, with customization being its advantage, one can literally decide how much can be spent on the computer or its components depending on their requirements. Make sure you determine how much you can afford to spend.

#4: Look for a reputed computer assembler

Since most of us aren’t well-versed with assembling a computer which might take too long for us to learn, it’s a good idea to look for a reputed computer assembler. The advantages are that you can discuss component options with him or her and even get in touch with them for support or maintenance later.

The basics of web hosting

40Written by Rack Alley

In the most basic sense, web hosting is an intangible service. There are cheap web hosting companies that rely on its intangible nature to promote these plans over the more expensive alternatives. In order to better understand the various pricing schemes available and arrive at the best decision, it is important to know what goes into web hosting.

Servers

This is one of the biggest sources of expenditure. With the exception of cases like LA colocation, all servers, and related equipment are purchased and owned by the hosting company. In some cases, higher fees are due to the constant upgrade cycle. This is a good thing as faster servers mean better performance.

Data Centers

The servers will be located at one of the many data centers used by hosting companies. The cost of this is a part of the charges included. These large buildings are designed specifically to host thousands or tens of thousands of servers. Some host will allow region selection like an LA data center.

Software

With the exception of a few open source applications, most software that both runs and runs on servers are proprietary. This is another one of the major costs in hosting. The difference can be seen when comparing the cost of a Linux server and a windows one.

Internet

Web hosting companies purchase web hosting just any other normal organization would. The advantage is that since the connections are large, these costs savings filter down to the individual hosts. However, since the connections need to be distributed amongst thousands of customers, there are strict limits and charges for exceeding those limits.

How Vacuum Metallization Plays a Role in Commercial and Residential Industries

The properties of vacuum metallization are seen everywhere – from refrigerators to high-end designer products.

vacuum-metallization-closeupVacuum metallization continues to be used for a variety of commercial and residential industries. The process of vacuum metallization is performed by combining a metal with a non-metallic substrate through the process of evaporation. Now, the most common material used in today’s industry is aluminum because of its low-cost, reflective properties, and thermodynamic advantages that it brings to a coating.

Aesthetic Finishes

Vacuum metallization is performed for a variety of reasons. For aesthetic purposes, it can add a nice finish to a product. The metalized substrate that creates the film can add a reflective finish that can be used with other processes to enhance the decorative look of the product. Additionally, through the use of a PVD system, one can dye the film to provide another unique look to the substrate. If you’ve ever wondered how certain products have such a unique and high-end appearance, it’s because of vacuum metallization.

Vacuum Metallized Surfaces for Insulation

The process of vacuum metallization is perform to increase the functionality of the substrate that is being coated. Furthermore, this makes it great for insulation purposes, primarily because of its increased reflective purposes. For commercial and residential fields, there are radiant barrier reflective insulation materials involved that are created through the process of vacuum metallization.

To sum it up, vacuum metallization is a process that is continuously used in a variety of industries. Its ability to increase the substrate’s functionality has essentially provided a unique way for industries to flex their versatility.

How Diamond Like Carbon Coatings Are Formed

diamond-like-carbon-coatings

DLC coatings are dense, consistent, and relatively simple to create.

Written by: Denton Vacuum, LLC

Diamond like carbon coatings, or DLC coatings, can be deposited using a variety of deposition methods such as sputtering, cathodic arc, ion beam, electron beam, and lasers. Through the process of physical vapor deposition, one can create a high quality and consistent DLC coating that can be used for a variety of applications.

Coating Process Sample

One of the most common ways to produce DLC coatings is through a sputter coater, which is essentially a vacuum chamber that has the ability to deposit metals onto a substrate through a complex process. The product can be placed within the chamber on a fixturing carousel when it is evacuated. The produce will then be preheated to a low processing temperature that will not exceed a certain temperature – typically 300 degrees Fahrenheit. The preheating phase will then condition the substrate for the coating to ensure that all of the moisture that has been absorbed by the material has been outgassed before the deposition process occurs.

The process will then transition into the ion etching phase where the product will be bombarded with ions and electrons. There will then be a scrubbing phase, which cleans the surface and remove any micro oxides. The process will then move on to the coating phase, which involves thin film evaporation to occur to begin the production of the DLC coating. When the underlayer coating reaches the proper thickness, the process will then transition into the DLC coating step, which deposits a dense and smooth amorphous carbon layer onto the product surface.

What makes in hosting or colocation viable?

Moving servers to the cloud or data centers and shutting down internal server rooms seems to be how and where most organizations are heading. However, outsourcing all server hosting Los Angeles resources may not actually be a good idea in some instances. It all depends on where the organization in particular gets its competitive advantage. Here are some examples of what makes server hosting Los Angeles internally viable:

Saas and technology companies whose technology is their competitive advantage will want to keep their servers in house. For example in house hosting is usually only done by larger companies that rely on revenue from those websites. This is because risks will arise and need to be mitigated and it is easier to identify when it is in house.

Hosting and Iaas companies that sell on the fact that their la web hosting is more reliable than the competition will also want to keep everything in house. Especially since they develop that infrastructure in order to maintain that advantage. Some or most of that advantage is in the software to hardware interaction which makes in house more attractive.

Companies that require very specific hardware resources will also find that they will need to remain in-house. Most providers will provide hardware that is specific to their own reliability and testing and that may or may not overlap with these hardware requirements.

The benefits of using a third party data center

Written by Rack Alley

3One of the biggest jobs in the construction industry right now is to dismantle server rooms and data centers of individual organizations. The reason: everyone is moving their server farms to the cloud or third party data centers. There are many advantages over maintaining your own, and now that costs have come down drastically, it makes more sense to move all possible workloads to the cloud. Here are a few of those advantages:

Location

While you might be able to serve your customers from your in house data center, nothing will beat the performance of a data center that is local to your customer. Los angeles colocation provides significantly improved performance over serving those same customers from another location.

Infrastructure

Larger data centers will have significantly better power systems, backup power, cooling and network performance. Even internet bandwidth will be cheaper and faster. One of the biggest though is that you will get around the clock support and monitoring by staff.

Provisioning

The ability to bring up server resource almost instantly on demand can only really be appreciated when you need to do it. Even for something like los angeles web hosting, a simple selection, confirmation will have it ready for access in minutes. The same can be done for servers, virtual servers and even high performance computing.

A Brief Explanation of Thin Film Coating Through the Means of Thermal Evaporation

Thermal evaporation has become one of the most commonly used ways to coat a substrate.

EXILIS_MDOne of the most common methods of thin film deposition is through the process of thermal evaporation, which incorporates the use of vacuum technology to apply coats of pure materials that stick to the surface of various objects. The benefits that a thermal evaporation system provides to the user range from efficient coatings to wide surface area reach. In most cases, the use of thermal evaporation is preferred due to its ease of use and efficiency.

The Process of Coating

The coatings that are created through the vacuum are called films. These films range in thickness and can be a single material or multiple materials in a layered type of structure.

The materials that are used can be pure atomic elements that include both nonmetals and metals like oxides and nitrides. The object that is coated is known as the substrate and can be anything from a semiconductor wafer to medical device coatings. The possibilities are endless as technological advancement has led to a wide array of uses.

Thermal evaporation begins by heating a solid material inside a vacuum chamber, which forces it to reach a temperature that releases vapor pressure. This evaporated material will then traverse the chamber and hit the substrate at a designated speed, which forms the coating, or film.

The material is often heated to its melting point and turns into liquid, which is located at the bottom of the chamber in a crucible setup. The vapor will then rise from the bottom of the chamber and inverted in appropriated fixtures – which will then proceed to coat the substrate.

Two tips for dealing with shopping cart abandonment at checkout

2Written by Secure Net Shop

Do you have shoppers visit your site, spend time picking items and then leave before they checkout?

If you are, you are not alone. This behavior is called online shopping cart abandonment. This is a common issue for ecommerce sites and can happen due to a variety of issues. Usually the issue is present at the point of abandonment. In the case of the checkout page, it can boil down to two basic issues that can be fixed quite easily:

Full shopping cart

Most shopping cart systems default to an abbreviated view of the shopping cart at checkout. You see the options to proceed without the checkout and an order summary but not much else. This issue is caused by users not completely certain of the details of the items they are ordering and a short summary is not sufficient. When the only course of action is to exit checkout, then they just close to the tab and go somewhere else. Fix this by showing a full shopping cart at checkout.

Full product details

Another point in relation to the above. Along with the full summary should be all the relevant details. Let’s use online clothes shopping. The checkout should the full list along with each specific option prominently. The options could be color, size, fit etc. In addition the quantity of each should be shown right next to the item. In addition the product images are essential, so the images should be high quality, clear and ideally represent the color chosen.

The Similarities Shared Between RNA Synthesis and DNA Synthesis

It’s been known that RNA and DNA carry out the process of transcription in a similar fashion.

RNA Synthesis

There are numerous similarities between RNA and DNA during the process of synthesis. When it comes to transcription, or RNA synthesis, there are four stages that occur: initiation, binding, elongation, and termination. All of these stages are extremely intricate and detailed, but, they all require RNA polymers to be bound to a template strand of DNA. Now, DNA plays an important role in the entire synthesis process. Essentially, they’re the template from which RNA copies from. The RNA nucleotides will go through a variety of sequences throughout the synthesis process until it reaches the specific sequence that it needs. It then detaches itself from the DNA followed by terminating the entire process.

DNA Synthesis

The process of DNA synthesis is fairly similar to the RNA synthesis process in that involves the binding of polymers. But, as it proceeds through the sequencing stages it becomes much more complicated, involving the creation and identification of new strands. When the DNA polymerases synthesize, there’s something known as a lagging strand that is created alongside the process. To help understand this, think of two strands synthesizing at the same time. However, one strand will synthesize continuously while the other strand follows discontinuously. This gap is what creates the lagging strand. The process of DNA synthesis then proceeds similar in the way that RNA synthesis does until the DNA template directs it to stop.

The Bottom Line

Both RNA and DNA synthesis work in a similar fashion to each other. They both go through the synthesis steps and discontinue upon the creation of the sequence. Additionally, they also follow similar patterns during transcription. Although DNA synthesis is viewed as the more complex process, RNA synthesis can almost be viewed as a simplified version.

Why Apple is gaining market share in the PC industry

mysystemsjournal2The Apple Macintosh line of computers have been gaining market share in the PC market lately. In a world where almost every PC manufacturer is losing market share, and taking significant losses, Apple is the one organization gaining share and making a healthy profit. This is primarily due to the halo effect of the iPhone. There is however more to its recent growth.

A lot of companies now have a bring your own device policy and treat your computer usage as a rental for each day. Most organizations purchase standard issue laptops and desktops and provide those to employees. Under new bring your own device policies, employees buy the computer of their choice. They are provided a daily “rental” for that computer and have to pay for any difference out of pocket. This has meant more Macs in the workplace as end users get to decide what computer they can use.

It has also helped that giants like IBM have discovered that Macs have a lower total cost of ownership over the long term and are in the process of migrating the entire 100,000+ user base to Macs. IBM have discovered lower Helpdesk and support costs along with faster onboarding of users when it comes to Macs. Previously one helpdesk technician was required for every 15 pc users, but with their recent Mac experience, IBM maintain a single technician for every 1000 Macs.

With these gains in the enterprise, a strong presence in the education market, expect Apple’s share of the market to grow for years to come.
