Technology evolves at mind-boggling speeds. And that makes us all scramble for the latest, newest, shiniest, ‘swaggiest’ gadgets. As a result, we end up sneering at any suggestion to buy second-hand or factory refurbished laptops.
But think about it. All the advantages of refurbished, pre-owned, for-sale-again, or reconditioned equipment.
They cost less
In good condition, refurbished dell laptops work just as well as new
The peripherals are almost always brand new
A good vendor can offer customizing options
On the other hand, buying new always costs top dollar. Plus, any psychological edge or swag wears off as soon as you purchase. There will always be something better, trending, or on the verge of being released. This is true for PCs, laptops, smartphones, smartwatches, and almost any other tech gadgets for personal or business use.
Buy “Like-New”
Have you ever bought your laptop and was excited to get it home and test it out. Then when you unwrap it you find something’s not right? Either it doesn’t turn on, or the screen resolution ain’t right, or a corner of the casing is cracked? Of course with a return policy, you send it back and the vendor promptly sends you a replacement.
Ever wondered where these rejects go? Well, it only makes business sense to sort out the issue and sell it again, right? But now, it can’t be sold as new. Yet it only required a keypad replacement, or a screen replacement, or maybe just a battery issue.
When you return your purchase, the retailer sends it back to the factory where it’s tested and if possible, repaired. It goes through the quality assurance stages once more, just like new, and put back on the shelves with an enticing discount and probably a renewed warranty. Would picking a brand new one offer any advantages over this sweet deal?
Get An Open-Box Deal
There are laptops that are returned even without hardly ever being removed from their packaging. Others are handled minimally before being returned.
Consider these scenarios: someone may return an unwanted gift. A retailer may ship 2 pieces for a single order. A customer may cancel an order. A laptop may lack one of its accessories or documentation in the packaging. There are many different scenarios where a laptop gets returned and can’t be sold as new.
For the second buyer, these factory refurbished laptops and refurbished desktop computers create an awesome opportunity for making huge savings without compromising on quality or making big warranty sacrifices.
Previously-Owned Bargains
As previously mentioned, w all love having the latest gadgets. This means lots of people trade in their gadgets for newer models. Some resell their almost new laptops for a competing brand. Whatever the case, factories find they have to reset and refurbish many almost-new pre-owned gadgets.
You can snag up a bargain on almost-new HP refurbished laptops that aren’t technologically too left behind. What most of these laptops require is hard disk formatting and resetting the operating system since the hardware and peripherals are still new.
What to Watch Out For
Don’t just go for refurbished laptops for sale. Go for a laptop that’s been refurbished by the original manufacturer or an established and reliable factory. Factory-refurbished laptops tend to have a higher QA standard rating than a laptop coming from a retailer.
Nonetheless, to avoid common pitfalls or being ripped off, there are some basic stuff you need to watch out for.
Limited warranty: Used laptops under 100 may come with shorter duration warranties compared to new units. The warranty may also cover less parts. Most factories and manufacturers will offer 90 days instead of the standard 1 year. Some manufacturers offer extended warranties at an additional nominal price.
Old Tech: While not always true, most refurbs tend to be at least one generation behind the current technology.
Battery Life: The previous owner may have mishandled the battery or charger. Battery life problems are usually not apparent when testing, and only become obvious upon multiple use.
Returns Policy: Go for a refurbished laptop that comes with a flexible return policy
Software: Make sure your refurbished laptop comes with original software, especially the operating system.
Factory Refurbished Laptops Vs Brand New: My Verdict
If you’re going for style over substance, then sure, get that new gadget and get your swag on. If you can’t stand the thought of using what once belonged to some stranger, then a factory refurbished laptop isn’t for you.
But if you want to get a practical machine that works as well as a new one and comes with a factory warranty/guarantee, then refurbished may be the way to go. If you want to get a tried and tested brand and model without bursting your bank account, you might want to consider factory-refurbished laptops. If you want savings to help you upgrade your laptop’s components, then factory refurbished will give you that freedom.

Fiber optic cables are a part of the infrastructure that powers modern networking technologies. These cables contain fibers of glass and transmissions of light to deliver data from point to point. This revolutionized a number of industries and fields, allowing for benefits such as a far greater range of data transfer without degradation of signal strength.
Since their introduction, fiber optics have begun to displace traditional metallic cables like copper. While older cables are still used in some limited areas, fiber has become the new standard due to the range, speed, and even reduced infrastructure costs. However, just how prevalent is the humble fiber optic cable in the modern world?
Cable Television:
Cable television is one of the more prominent uses of fiber optics. These services feature from the increase in bandwidth and transfer speed, allowing for crisper, higher definition visuals and audio. The transmissions are also less likely to suffer from interference from external sources, provided the cable itself remains intact.
Originally, copper wires were used for these cables. These became displaced due to the cheaper cost of fiber, along with the other benefits. Copper has a slower speed and there is a risk of the signal being degraded over distance, forcing more infrastructure to maintain the signal strength.
Internet Access:
Most people will be familiar with fiber optics due to the internet. In some areas, providers are upgrading existing connections to fiber optics to provide a better service. These provide stable, high-speed internet speeds in various areas. The cables used are also lighter, less bulky than the older copper ones, though you sacrifice a small degree of flexibility in the process.
The biggest benefit of using fiber optics for the internet is the same as in cable television. This new technology boasts a far greater data transmission and bandwidth, opening users up for higher speeds than were previously possible. This, combined with the stability of the transmission, has resulted in a smoother, more enjoyable web surfing experience.
Telephone Lines:
One of the major advantages of using fiber is that the transmission does not degrade with distance. This allows it to excel in connecting systems and networks together between cities or countries. This has resulted in fiber optics being used in the oldest telecommunications industry in the world: telephones.
Fiber optics has allows phone conversations to be cleaner and more reliable, even over long distances, than before. Connections are faster, there is reduced lag in conversations, and the audio quality is clearer.
Medicine and Dentistry:
It might surprise people that fiber optic cables see use in medicine, dentistry, and research. Endoscopy relies on these cables for optical communication. The technology uses a minute, bright light to illuminate the area targeted by surgery, which allows for a reduction in both the size and number of incisions required to get things done. With reduced incisions, recovery periods are much faster.
Biomedical research and microscopy are also seeing fiber optics used in a similar manner.
On-site Inspections:
Because of how useful the notion of attaching a tiny camera to a fiber optic cable is, the technology used in endoscopy has also seen use in inspections. Everything that has small spaces that need to be checked out but can't necessarily accommodate other AV equipment or a human being can be inspected using these cables.
Engineers and other on-site inspectors make use of this technology. They look in the areas that are hard, if not impossible, to reach otherwise. The clarity of the visuals helps make sure the inspection results are as accurate as possible.
Computer Networking:
These optic cables are also used in broader computer networking applications. If you need to connect all the computers in a single building or across structures within close distance of each other, this can be done faster or easier with fiber optics. Anything connected to this system will see a decrease in transfer times and improved data transmission rates within the network.
Lighting and Decorations
Fiber optics also see use in decorative lighting.
These cables provide an easy, attractive way to modify a lighting project. They are quick and reliable and don't generate as much heat as more traditional designs or materials. More often than not, fiber optics are used for decorative fixtures and small illumination, such as lights on Christmas trees.
Military:
Given that data security is important to the military, fiber optic is not surprisingly used there as well. The data is easier to secure in these cables due to the reduced risk of interference. The speed also allows for better coordination of all systems. This makes fiber optics an ideal tool for data transmission, communications, and networking in a military context.
Cars:
Finally, the automotive industry uses lighting as part of the safety features and comfort of a modern car. Fiber optics see use in lighting up the interiors and exteriors, since it conserves space but still provides superior light. The ability to transmit signals also lets it play a part in various control systems, particularly safety features which must react as quickly as possible to prevent injuries or save lives.
Conclusion:
Fiber optic cables are now a part of the modern networking infrastructure of the world. However, they also see use in other areas, fields where their transmission speed, reliability, or even size can be useful. Who knows what other uses we might find for fiber optics in the future?

Mobile testing guarantees that the apps and smartphones are safe, reliable, and easy to use.
Several tests are conducted on mobile devices to evaluate an application's reliability, functionality, and usability. Mobile testing can be divided into testing of mobile applications and testing of mobile devices. Mobile device testing verifies and validates both the physical components and software aspects of a device to authenticate its quality. It evaluates aspects like the screen, apps, camera, etc. On the other side, mobile application testing is a procedure used to test applications that are being created for mobile devices. The primary goals are to test the apps' usability, stability, and functioning. It makes sure that the chosen application, in terms of connectivity, hardware, and software, is compatible with the chosen device.
For an app to survive in the market today, mobile application testing is essential. The application is also tested in numerous other areas, such as its performance, security, and UI, to provide the best quality for the end users
Types Of Mobile Apps
There are three primary categories of mobile applications:
Native mobile apps
Native applications are platform-specific. In other words, they were created for a particular platform or operating system. It may be a Windows SDK, Android SDK, or iOS SDK. They have the extra benefit of being faster and more dependable in terms of performance because they concentrate on a single OS, but they are expensive to maintain. Such programs include Skype, Google Maps, and Snapchat, for instance.
Mobile Web Applications
Only mobile browsers are compatible with mobile web applications. They are accessible through mobile web browsers like Chrome and Safari. They are created using web-based languages like HTML, CSS, and JavaScript. Additionally, it is inexpensive and does not need users to install or update it. These include websites like AliExpress, OLX, Flipkart, etc.
Hybrid Mobile Applications
Native and web-based mobile apps are combined to create hybrid mobile apps. They can operate through browsers but can also be installed on native application devices. These apps are easy to create and affordable, but they lack the speed and power of native apps. These include services like Instagram, Uber, Gmail, etc.
Now to test these apps many testers and developers leverage automation test tools like Appium. Let's quickly define what Appium is.

Keep reading this article till the end to learn more…
What Are SDK Files?
But before talking about "which is a benefit of using server–to–server app conversion tracking over an SDK?" it is important for you to know a little about the SDK files. So what are they?
The full form of SDK is Software Development Kit. It is a set of tools that are needed to help the software developers make or create the application for a particular platform. They are generally made and provided by the manufacturer of the hardware platform or a programming language.
There are a number of things that are included in an SDK file. According to Red Hat, "a basic SDK will include a compiler, debugger, and an application programming interfaces (APIs)." However, these are not the only things that are included in the SDK files. They can also include things like drivers, libraries, documentation, and testing/analysis tools. And network protocols.
Some of the best examples of SDK files are:
Java Development Kit (JDK)
iPhone SDK
MacOs X SDK
Windows 7 SDK
Cloud SDK
So, What Is S2S?
Well, if you are planning to choose a server-to-server app conversion tracking over the SDK file, it is important to learn a bit about S2S as well, isn't it?
A server-to-server or S2S tracking is a method in which the data is shared from one server to another. The major benefit of this is the fact that there is no need for cookies on the website at the time when a visitor enters the website.
So, if the software does not take cookies, how do they get the data, and how can they track it? Well, I have the answer for you!
The S2S tracking works in a simple way. It works by generating and storing the unique identification. This UID can be anything in the form of the clicks made by the user or even by the impression on the ads. This is how the data is collected.
When the same user visits the website again and takes part in such an action that will be tracked, the UID matches, and that is how tracking is done! Pretty simple and efficient, isn't it?
Now let me explain the answer that you were searching for!

Explanation Of "Which Is A Benefit Of Using Server–To–Server App Conversion Tracking Over An SDK?"
Now that you know what an SDK file is, it is important for you to understand the explanation behind the question, "which is a benefit of using server–to–server app conversion tracking over an SDK?"
So here I go!
The server-to-server or an S2S app conversion tracking helps the customers to send the details or credentials that they want to, to the website. These details or data are required for tracking the AdWords app user conversion. In this method, the AdWords app sends the tracking details from their server to the Google server during the event of conversion.
On the other hand, the SDK files are not easy to implement or operate. When they are incorporated into an app, most of the time, you are supposed to add a piece of code. Furthermore, the tracking is also not controlled by the users. This also adds to the worries as they are not the ones to decide whether the process of data tracking is safe or not.
Additionally, the most important benefit that you might have in choosing server–to–server app conversion tracking over an SDK is the fact that S2S is a much easier way of implementation. You will not be able to face any errors or bugs. The SDK, as I have already mentioned, has many complex technicalities.
Thus, if the file is not implemented properly, you will have to go through the annoying experiences of bugs in the app.
Wrapping It Up!
SDK Files are the ones that are kind of a binary file type that some of the software use. They are the software development kit with which a lot of the software is embedded.
However, if you are considering choosing server-to-serve app conversion tracking over an SDK file, then there is one major benefit. And that is the fact that it is much easier to implement. But, of course, if there is an error while implementing the SDK file and the tracking code, there could be bugs.
In case you were searching for the answer to "which is a benefit of using server–to–server app conversion tracking over an SDK?" I hope that this blog has been of help to you.
