Investing in a new PC or laptop requires a lot of analysis and reviews of the different machines so you could get the best one for your work. Buying a laptop is a serious financial investment that you need to approach carefully, mainly because there are a lot of different brands that sell these and you often get confused with the low prices. You probably think that there must be a catch as these are so cheap.
But in reality, there is no catch at all. When it comes to buying a refurbished laptop, a lot of people is scared of these as they think these are low-quality and used machines that do not work well anymore. However, that is not true at all. We will list in this article the reasons why you should go for a refurbished device.
Even though you might think that these will not last long, you are wrong. All refurbished units come with the highest quality, durable hinges and high-quality materials that provide your laptop with long-lasting performances.
The refurbished laptops are basically machines that are have not been used a lot, but due to the company’s policy, these must be replaced with the new ones. Therefore, any company would buy a good laptop and not a single one would buy something that has questionable quality and performance. Therefore, you are safe when it comes to the quality of the machines as these are usually Dell or HP models.
Whenever you buy a device, you expect to get a warranty with your purchase. Every refurbished laptop comes with the 12 months warranty and if you do not see it coming with a warranty, the company that sells these is a bit shady.
All these are high-end machines and business configurations so it is natural that someone who “repaired” these offers a warranty. Therefore, you do not need to worry about the servicing for the next 12 months since you can repair anything for free, as long as you did not make any damage to the machine. These machines probably did not work more than 1,800 work hours, which is considered almost to be new.
Whenever we plan to buy something, we also plan a budget that we would stick to. As you probably could see, the refurbished machines often come at the more than affordable prices as the company that used these tries to sell them and make a few bucks.
Therefore, they just want to replace these with the new ones and therefore they do not care too much about money. This is where the sellers come in – they buy the machines at cheap prices and then increase the price a little bit to make some profit. While they make a profit, they offer low prices that attract the buyers.
Let’ agree with the fact that accessing the internet shouldn’t be an issue when you are inside your home. It’s easy to connect, it’s safe, and finally, it’s a fact. However, when you are outside, it another story.
A lot of people don’t have data on their smartphones, so they have to rely on the public network. These days, you can access Wi-Fi in more places than ever. It enables you to keep in touch with your friends and work.
But, the public network is less secure than the private one. Therefore, you need excellent firewalls that works against threats. So, here are a couple of tips to protect your information.
Whenever it’s possible, try to use trusted networks, for example, Starbucks, or McDonald’s. They are less likely to contain threats, and people and companies operating them are already getting money from you.
You must keep in mind that no public network is 100% secure. The safety mostly depends on who provides the services. For that reason, you should stay clear of Wi-Fi that pops up on your phone in a shopping mall, or Wi-Fi that is operated by a third party.
They might be legit, but what’s their purpose if anyone can connect for free. How are they making money? So, use your commons sense before you access such a network.
A couple of years ago, Google Chrome started notifying users about the sites they are visiting. Now you have a chance to see the difference between an unencrypted HTTP and an encrypted HTTP connection. The first one is labeled as unsecured which can serve you as the first warning mark.
You will especially need this warning when you are on a public Wi-Fi. So, when you are browsing over HTTPS, users who are in the same public network can’t snoop on data that is exchanged between you and the website’s server.
Some public networks will ask you to provide sign up or provide personal details, such as email or phone number. Don’t fall for their apparent attempt to get ahold of your info.
If you need to connect to the internet, then use trusted recourses and stick to decent places. You can also use an alternative email address designed for this purpose. Also, some phone or cable carries may offer free hotspots in your current location so that you can explore that option as well.
Before you connect to any public network, make sure to check the terms and conditions. You might not understand every word, but you will be able to notice any significant red flags.
Of course, there is nothing wrong in terms and conditions. They help the provider protect its services. But, if they ask you to install additional software, or browser extension, run away.
Usually, there is a threat lurking behind that can jeopardize your data. Therefore, you may benefit by installing a VPN, to stay safe on public Wi-Fi.

The potential of implementation of ICT systems in nearly all fields of people’s activities nowadays is yet to show its full capacity, but the powerful impact is more than obvious in science, education, banking, human interactions and much more. However, for a software engineer, implementation of ICT systems into healthcare system is one of the most important and challenging at the same time. For quite some time, ICT methods facilitated healthcare system only by providing a more efficient administrative aspect of healthcare.
The scope has expanded over time significantly and, as experienced and educated software engineer, I had the honor to monitor the implementation of ICT methods into several hospitals and polyclinics that broke through limitations of the administrative field into actual medical practice. The software infrastructure provides easier ways of communication between hospitals, storing information about patients, facilitates interaction between doctors and patients, prevents medical errors and empowers medical procedures. Here is my review of three major aspects where ICT had an impressive impact on the healthcare system.
Electronic Medical Record Exchange refers to a particular ICT platform designed for sharing medical documentation among public and private hospitals and health departments. Since I’ve spent too much time privately carrying around tons of papers and various personal medical reports from one doctor to another, I found this electronic infrastructure to be a blessing. However, the software engineer within me approach this platform professionally and found qualities to outnumber challenges and issues. Namely, EMRX connects two clusters of medical records, enabling equal access to many doctors in different hospitals to the medical records of the same treated patient.
The software is rather powerful and supports myriad of data formats, which provides sharing of lab results, X-ray results, medical reports, drug prescriptions and much more. The data flow is smooth, efficient and reliable and coordination among all medical staff involved in the treatment of a single patient is empowered. Although this facilitates treatment and various medical procedures a big time, there is a major flaw in the system. Since EMRX is essentially “opt – out” based application, it requires sophisticated measures of protection and safety to protect the mere document of malicious software, as well as to ensure the privacy of patient’s data and results. The last issue opens a big field for all software engineers and challenges them to improve this fundamentally excellent program.
Since an average human life spans all up to 80s nowadays, plenty chronic patients require regular controls, checkups, routine therapy or occasional modifications of the treatment. This chronic treatment involves several levels of the health care system, including a general practitioner, various specialists, lab technicians and others, with the mere patient at the end of the chain. There’s a high flow of medical documentation belonging to the same patient and regarding the evolution of the same disease. Chronic Disease Management Program is designed to create a close link between all levels of health care system involved in chronic treatment. Its task is also to keep all the data of a single patient systematically archived, to enable comparison and analysis of the disease evolution.
Finally, it provides solid control of the chronic illness, while at the same time prevents complications and reduces treatment costs. CMS system uses info communication technologies to collect the data, keep the track with the patient and enable two-way communication between doctors and patient.
Finally, there are several particular info – communication technologies that are applied directly to various medical procedures. The one I find the most useful and the most (so far) developed is so called PACS communication system. This application provides storage, distribution, and presentation of various radiology pictures, including MRI, CT, PET, and mammograms, converting them into consistent data format available on various digital devices later.
The most valuable currency in our modern digital age is the valid information. Convenient, efficient and above all – secure communication and information sharing is an essential aspect of functioning to most enterprises, small businesses, as well as to individuals. I’ve been a member of several teams of ICT engineers over the last few years, maintaining complex corporative networks and systems of unified internal communication, and two major trends became evident to me.
The ICT systems are heading towards wide implementation of IP-based communication within enterprises that will provide myriad of convenient services, such as instant messaging and e-mails, voice, and video, desktop sharing and conferences.
The other trend is centered around extensive security measures that will protect all the valuable data, personal as well as corporative. The threat of malicious software potentially damaging complex ICT systems is constantly present, so I’ve decided to put down a review and some expert’s advice on how to protect your information stored on various digital devices.
With over 300 million of new malware, viruses and various other malicious software attacking during a single year and damaging mostly personal data bases or data bases of small businesses, I strongly suggest you not to underestimate the importance of basic anti-virus and anti-spam protection. Many reputable manufacturers are providing powerful antivirus applications, such as Microsoft, SonicWall, Webroot and others so make sure you purchase system-wide anti-malware and anti-virus 24/7 protection and maintain it regularly. Have in mind that active monitoring and filtration of the incoming data are essential for protection. Also, I prefer to impose strict limitations on employees regarding website blocking and surfing. My experience has proven cloud based protection of emails as the most reliable method.
When asked to provide high-quality protection to personal user accounts, I suggest two-factor authentication system. The two-factor authentication system includes additional safety layer aside traditional username and password log in. Various codes designed for a single-use are sent to another personal device connected to the account (usually a cell phone), and the user is obligated to enter this code to complete authentication.
Popular security methods often provide average protection, but in this case, I agree with the standard option. Encryption renders data that is accessible only to approved users by using decryption key and code stored in a secure location. At first, I used to implement the system onto PCs of my clients and maintain it on my own, but teaching and instruction turned out to be more efficient. I decided to simplify the procedure to all my customers and train them to apply encryption on their own. So far, no unauthorized access was reported to me.
As the experienced software engineer, I’ve been dedicated to constant fighting against software designed to harm stored PC data. The fact is that most threats to internal information and communication come from users who are trying to access risky or inappropriate websites. Another source of threat is installing and running malicious applications, neglecting the anti-virus warnings. In all of these cases, I solve the problem by implementing the system of application white listing. The pre-formed list of allowed applications is encapsulated by this application and all other applications trying to access the computer are blocked.
Security measures that I mentioned above are some of the conventional approaches I tend to implement into maintaining personal and corporative information and communication systems on a daily basis. Depending on the complexity of the internal network, power of servers, number of clients interacting and the flow of the data, there’s a broad range of other effective safety methods I will discuss in my other article.
The initial exchange of information that happens at “sea” is considered to be a standard maritime message marker. The trade can occur between “ships” or between ship and “shore” and it involves the following stages.
Even the smallest incentive unit, also known as the unit of conversation is called exchange. It must be referred to a particular topic, and it has two ends. One is held by the controlling station, which means the first speaker and the other is responding station also known as the second speaker. When you want to make contact with the responding party, you need to use clear language and specific phrases which are used in this type of communication. Your questions need to be short and coherent if you want to receive an appropriate answer.
This represents everything one speaker asks or says at one end, it the time between his pressing and releasing the speaker key. The standard procedure when finishing the turn is to say the word “over.” It means that his request or question has been completed and it’s time for the other party to respond. His turn is over or is given to hearer, who now takes his turn to process and delivers the information.
When speakers manage to realize two turns to a single topic, subject of conversation, a maritime exchange happens. When they talk about a particular subject and use more than one turn, they are creating a maritime VHF conversation. There is one most important part of the turn: move or act. It means that speaker contributes actively in the exchange of information and participates in the conversation. He can use various word, questions, phrases, and sentences which can help him to express his intention or request. The vocabulary participants use pretty basic and usually consists of one word, but in cases of emergency, they can use the entire sentences. This is one of the reasons why you need to be well informed about their structure and construction before you intend to make a maritime VHF conversation.
Have you ever wondered which events change the world of computer technology and set the digital progress off? The kids nowadays don’t even remember the age before computers, smartphones and the access to the high-speed internet. But, how did everything start and which events lead us to become a digital society?
When thinking about the alphabet, the first association goes to Mesopotamia. It was the initial “tool” used to keep and transfer information. It wasn’t long before people discovered how to manufacture paper and writing materials. The first writing material was a wet clay, and later papyrus plant was found, and people started producing primitive forms of paper. This trend spread throughout the world, but soon new problem appeared – how to store all that data over a long time? It eventually resulted in the first books and libraries and Egyptians developed scrolls. In this way, they could keep all sorts of information much easier.
In this stage, we finally start to notice some connection between primitive forms of information technology and the systems we use nowadays. The Mechanical age starts around 1450 and ends in 1840. At that time, a large number of new technologies has appeared. The peak of this era was the first analog computer which could do some primitive functions, such as dividing and multiplying numbers. Several impressive machines were invented during Mechanical age, and even though not any of them was nearly effective as modern – day computers, they still had a significant role. The only problem with those machines was their size; they were huge.
Between 1840 and 1940 some major things have happened and here we have early inventions of telecommunications, and soon after that, the first telegraph was invented. In the late 1800s the first radio was designed, and in 1940 the first digital computer was created. This era changed the way how we think and prepared us for electronic revolution.
This age stated in 1940, and we are living it now, the era developed the first computers and functional operation systems, which lead us to have high – speed digital computers. The first system was first designed for U.S. Army for artillery firing tables. This machine was so big that tool 680 ft.2 and it weighed 30 tons. The revolution started with the development of the first programming languages, such as COBOL and FORTRAN.
Digital era has finally come, and we have some of the best software, devices, and gadgets developing as we speak now. Many people still don’t understand how some things work and the best source of information is IT forums. They will provide you a full scope of data, technical support and troubleshooting advice for all of your devices. But, nowadays, you can find a large variety of them on the web, but the main question remains – how much they are helpful? In this article, we are going to discuss one of the giants in the online community, and that’s CNET.
CNET is one big forum which has several categories divided into small forums. The platform is easy to navigate and simple to use, which is important when you are looking for something. Most users want to find their answer quickly, without browsing the web for hours and CNET provides you exactly that. Everything is organized into sections, so when you are looking for something, it won’t take you more than 15 minutes. The developers of this forum actually put some effort in it, and everything is arranged so that user spends the minimum amount of time while getting the answers. Another great thing about CNET is that it warns you about posting your private information online because it can be abused.
If you are bored researching the entire forum in order to find the answers, you can always use a question form or start a new discussion. But, before you can utilize this tool, you need to be logged in, which means you need to open a new account. The entire process is done in a couple of minutes.
First of all, it has a large number of users. Secondly, here you will find actual information which can lead you the solution of your problem. Not only regular people use CNET, but also IT experts and they are the ones who will fix your issue. Individuals who attend this forum are genuinely helpful and ready to give you a hand.
The index of cyber security is a measure with perceives the risk. The higher the index, the risk is bigger, the same rule applies in the opposite direction. This tool is highly used in all aspects of society, especially in the governmental and industrial sector. Nowadays, many organizations and companies are struggling to keep security under control and fight cyber attacks. In this case, we are talking about major corporations which are exposed to many hacker attacks, and they are trying to keep the same level of protection. Apart from hiring IT experts, there are special tools which can help you estimate your level of risk and help you protect your data.
Most IT experts use this tool in their everyday work. They need to establish the level of risk and know when to protect the corporate files and data. In some cases, if the hacker attack is too strong, not even the best experts can stop it or prevent it. We now have various cyber attack groups which praise on their skills and while trying to deceive the public that they are doing the right thing. The index of cyber security can help you significantly to recognize the threat and to protect the corporate data. But, if you don’t put a high defense, it won’t help you stop the attack.
Only if skilled professional uses this tool, it can have a significant impact on government and corporate institutions. On the other hand, in the hands of an armature, this tool is useless. Many experts from the online community can combine their knowledge in order to improve the performance of this tool. At the same time, it will provide you series of data useful for stop any breach of security. The main advantage of this software is that it gives you information in real – time and its results are correct. If you suspect an even minor threat, raise your defense, because the bigger impact is yet to come and you will be unprepared.
We live in a world where anything is possible, and if someone wants something from you, they will find a way to get it. In the recent years, online security has become a big issue and not only businesses, but regular people experienced some sort of a hacker’s threat. In many cases, people are to blame because they didn’t take necessary steps to protect their data and made the job easier for hackers. Detecting an early attack is a critical thing and the first hour is the most important one. It is the hour where every minute counts. Unfortunately, amateurs don’t have the experience to deal with skilled hackers, but there are still some things you can do to protect your data.
No matter what device you are using, you should lock down your computer, smartphone, and accounts. If you are storing your data online, then this is even the bigger reasons to have all sorts of passwords. On the other hand, if you are running a business, your employees are required to use passwords on a daily basis. In many places, people are still complaining about using them, but sometimes they can save your entire business. The crucial thing is to have a good team of IT experts which will monitor day to day task and establish good protection system.
Stop using your pet names, your birth date, or even your name as the password. In this case, even the experts can make a mistake. A few years ago, we had an example where Mark Zuckerberg, the owner of Facebook used 123456 as a password for his Facebook account and when it was discovered the whole world didn’t believe how obvious his protection was. But, 30% of people still use this type of protection. So, if you want to protect your accounts, use something that is a bit difficult to breach, for example, a song lyric of your favorite artist. It’s catchy, but still long to breach. Also, have in mind that it is recommended to change your password at least every three months.
