How to choose a processor? What to look for?

The processor is a key link in the composition of a modern computer. If earlier all the tasks that he performed were processing commands and services of the operating system, now much more is required of him. The gaming industry has developed significantly in the modern world: there are projects that can use a large number of cores and threads. As for working applications, they have also changed and now require more serious computing power.

On the one hand, choosing an office, home, or gaming processor is not such a difficult question. However, you definitely need to determine your needs, navigate a little in the characteristics and price ranges. Therefore, it’s worth a little understanding of this issue so as not to overpay too much and understand which processor is better to buy for your purposes.

Let’s deal with this issue together. There will not be a comparison of processors, substantive recommendations, we only focus on the overall picture of the processor market in 2020 and give some tips on what to look for when choosing.

Overall computer performance

processorMany believe that the processor does not greatly affect the overall power of the PC. However, it is indeed a key link among all components. After all, it is useless to have a high-speed SSD if you have a dual-core processor. In this case, you simply will not feel the gain from the fast drive due to the fact that such a CPU is not able to process even the simplest commands quickly. The same goes for the visual part: for example, what’s the point of a high-performance video card if your PC freezes constantly. Therefore, absolutely in any tasks a powerful processor is required, other components only complement it.

How is the processor arranged?

If we analyze the physical structure of the CPU, then this is what it consists of:

  • Cover that protects the inner crystal and other elements
  • Nucleus
  • Substrate to which all parts are attached
  • Cache memory
  • Socket – a socket with which the processor is attached to the motherboard.

Number of Cores

If we differentiate between the number of cores in different segments, then the budget ones will receive about 2-4 cores, the middle segment – 6-8, and the premium – 8-16 cores. There is an idea that the more cores – the better. However, there is one nuance in this matter: programs that do not know how to distribute the load among the cores will work faster on a dual-core processor with a higher clock speed than on a 4-core processor, but with a lower frequency. Based on this, the clock frequency is not the main indicator in determining the processor performance. It is impossible to unequivocally answer which frequency is better, however, time and market still dictate their own rules and standards. Therefore, the optimal clock speed is considered to be at least 3 GHz with a 4-thread processor.

Type and frequency of supported RAM

The frequency of RAM also affects the speed of the PC. The higher this indicator (measured in megahertz), the faster the information is transmitted for processing. However, considering the issue of RAM, you need to keep in mind the characteristics of not only the processor, but also the motherboard. The supported frequency and type of RAM must match both the CPU and the system board.

What is not worth paying attention to?

intel-amdFor many, the determining factor when choosing a processor is their manufacturer. Someone prefers the processors of one company, someone else. The main competitors in this area are Intel and AMD. When comparing processors with the same frequency and number of cores, Intel wins. However, AMD wins the price / quality ratio.

Therefore, if there is a question about which processor to choose, it makes no sense to doubt, you need to look at the quality characteristics and price, and not the logo printed on the processor.

General recommendations for choosing a processor

  • Decide what tasks your processor will perform. If in normal mode you have about two resource-intensive programs working, then it is better to buy a 2-core processor with a high frequency. If you use many programs at the same time, it is better to buy a multi-core processor of the same architecture, even if the frequency in it is lower.
  • If you need a PC not for sophisticated games, then you can save on the purchase of a video card by purchasing a hybrid processor (with a built-in video card)
  • Do not chase new products, they are usually only 10-20 percent faster than their predecessors. And this is almost imperceptible in everyday work, but they are much more expensive, and sometimes also require replacing the motherboard.
  • When choosing a powerful CPU, consider that the power of your power supply is sufficient based on the power consumption of the processor and the entire system unit as a whole.

Poor wifi speed? What to do to make the Internet work better?

In the modern world, the information computer network Internet has played a very important role in all spheres of life. He entered our life so tightly and for the majority has become simply necessary. For example, many users work or promote their business through the Internet. Therefore, it is not surprising that to achieve these goals you need a stable high-speed Internet connection, which allows you to work quickly without delay and damage to business.

скорость интернетаHowever, it is not always possible to achieve maximum Internet speed, but today it is especially difficult. Due to the forced quarantine in Ukraine, almost all commercial and state institutions transferred their work to a remote mode. Consequently, all those who work at home began to consume more Internet traffic. In addition, all family members were also at home: someone is engaged in distance learning, while someone just watches news or movies. In any case, the network load has increased several times.

Many Internet providers claim that during the quarantine period the amount of data transferred has increased by about 4 times. Therefore, companies are starting to expand their channels and strengthen their infrastructure.

Why is Wi-Fi slow and how to fix it?

  • Check the specifications of your router.
    Many providers can provide connection speeds of up to 1 Gb / s. However, when choosing such a provider, you must take into account the bandwidth of your home router. He may well not support such a speed. Therefore, before buying a router, you need to make sure that it can provide the maximum speed that the Internet provider promises.
  • Another possible reason for a poor Internet connection may be a speed limit; the provider’s operators could increase it as part of anti-crisis measures. You can ask this question by contacting the support service of your service provider.
  • Wrong location of the Wi-Fi router. If you have thick walls or a large room, then wireless coverage will really be bad. Therefore, try to place the router as close as possible to the place where you most often use the network.
  • Cable is the best solution. We are all accustomed to a wireless connection, because it is convenient and practical. However, if you have to work at home for a long time, and you need Internet speed now, you can lay an Ethernet cable to your workstation and connect your device directly to it.
  • The cause of a slow Internet connection may also be a virus infection on your device, and possibly even only a browser. Therefore, it is worth checking the gadget for viruses and “cleaning” it using anti-virus software such as ESET Nod32, Bitdefender, Avast, etc.
  • Often, poor Internet speeds can be caused by using an outdated version of the browser. Try to update it, or replace it with another.

How to check the download speed of the home Internet?

  1. First of all, you need to test and compare the speed when connecting to Wi-Fi and directly connecting the cable to your laptop. Thus, you can eliminate the influence of the router on the connection.
  2. When testing the speed, be sure to disable all torrents, downloads, updates, and other programs that use the Internet.
  3. Make sure your device is free of viruses. Check speed also on other devices.
  4. If you can’t fix the problem from the first three points, you should call your Internet service provider and declare that the Internet speed does not match your tariff plan.
  5. If everything works directly when connected directly, it really can be in the router. Then you need to check its settings. Our technical experts can help you with this.

Therefore, a large flow of users, of course, significantly increased traffic and created problems with speed. However, it cannot be ruled out that you are using obsolete or defective equipment, and forced insulation is an excellent reason to replace it.

How to successfully tender under quarantine?

In an environment where all businesses and government agencies are forced to move their jobs remotely, there are more and more questions about how procurement can be successful in such circumstances, and what tools for teleworking will most help?

Can I suspend purchases for quarantine? No, there is no such button in Prozorro. But you can always plan your own procurement plan and decide how much you need them now.

Most customers are accustomed to meeting the tender committee offline and to jointly decide on a particular procurement. Today, everything is possible and even necessary to do online.

For example, if you need to discuss the tender documentation, you can do so in Google Docs or other text editors. Google-Docs has the ability to share text, share comments, or make suggestions for specific changes.

How to review the bids?

Likewise, by email or other messengers, the Tender Committee secretary may inform all other TC members that the Bidder’s proposal is currently being considered and the tender shall be referenced. And each TC member can independently enter the tender card and view the Prozorro Participant’s documents.

If you need to discuss the details of the purchase further, you can create an online appointment on Google Calendar. In addition, there are many remote tools available for video conferencing and calling. Including:

How does a manager sign a contract?

By agreeing to the terms of the agreement, the Participant may sign it on his / her own behalf and send the courier to your manager or any other authorized person. The Participant then signs the contract and scans or takes a photo of it and sends it to you for publication.
If you did not receive a scanned copy of the contract, but simply photos of different pages of the contract, then translate it into PDF format and prepare for publication.

To publish documents to the system, you do not need to be in your workplace, you can do it anywhere you have Internet access.
If the procurement is handled by an authorized person, it becomes even easier to organize one person’s work. There are many mechanisms in place to help organize remote work and work online. Moreover, such tools will greatly save your time now and save you time in the future.

Therefore, a successful tender under quarantine is possible! And modern remote control solutions and technologies will help you do this.

Who is the authorized person under the new version of the Law on Public Procurement?

Due to the amendments to the Law of Ukraine on Public Procurement (No. 1076), customers are increasingly asked questions about the activities of authorized persons.

We will remind, according to the new edition “tender committees” will be liquidated from January, 1st, 2022, and responsible for carrying out of purchase already appoint “authorized persons” already. Such an innovation is one of the tools for professionalization of public procurement.

Who is the “authorized person” and what are his / her responsibilities?

The AP is an official or other person who is an employee of the customer and is responsible for organizing and carrying out procurement procedures in accordance with applicable law. It is appointed by the customer by:

• Providing an employee of an existing state with the functions of an authorized person as additional duties with the appropriate additional payment;
• Conclusion of an employment agreement in accordance with the law
• Entering into the staffing list of the individual position, which will be the responsibility of the AP.

zakupki
Who can be an authorized person?

Can the AP be the head of the department, chief accountant, director, etc.? Yes, they can all get the responsibilities of an authorized person by placing additional responsibility on them. However, they must have a college degree, usually a law or economics degree.
In addition, the APs must confirm their level of knowledge required to work with public procurement on the web site of the Authorized Body through free testing.

The contracting authority is also entitled to appoint several authorized persons, provided that each of them will be responsible for the organization and conduct of specific procurement procedures.

The exceptions that may not be appointed by the AP are officials, representatives of the procurement participants, as well as people’s deputies of Ukraine, deputies of city, district and regional councils.

Responsibilities of the authorized person

The duties of the authorized person include the disclosure of complete and accurate information about the purchase of Prozorro. It will be her responsibility to complete the annual plan in the public procurement system.
AP is obliged to act in the interests of the Customer and to ensure fair and objective procurement procedures.

Accordingly, the authorized person:

• Organizes and conducts procurement procedures
• Forms an annual plan in Prozorro
• Performs the functions of compiling, submitting and storing public procurement documents

zakon-ukrainyIn case of violation of the requirements of the Law of Ukraine “On Public Procurement”, the authorized person incurs personal responsibility in accordance with the current legislation of Ukraine.

In general, the AP does the same thing as the tender committee, but does everything individually and accordingly is responsible for its decisions.

Thus, the introduction of a profile position increases the efficiency of procurement and reduces the risk of unsuccessful procurement procedures.
If you still have questions about the activities of authorized persons, please contact us and get detailed advice on this innovation.

What changes will bring Ukraine a new law on public procurement? 5 innovations that will affect the reduction of corruption schemes

In September 2019, the Rada adopted a new law (No. 1076) on public procurement, which will enter into force on April 19 this year.

Let us consider in more detail how new changes will affect procurement, as well as corruption schemes of customers?

• As you know, customers often reject proposals from participants if they contain errors, even if they are insignificant. However, according to the new law, it became possible for participants to change / correct a mistake within 24 hours after its detection.
With this opportunity, it will become easier for participants to participate in procurement and compete with each other. Indeed, earlier, the customer often deliberately rejected a particular tender offer, using errors in the documentation only as an excuse for his corrupt purposes.
Now he does not have the right to reject the proposal, because of state bodies that control all his similar actions.

• The next change in the law that you should pay attention to is the newly introduced concept of “abnormally low price” (ANC), which the supplier will have to justify to conclude the contract. Also, this value will be highlighted in the trading system.

What does all this mean?

zakupkiThis means that a price offer that is 30% less than the next, or 40% less than the average value of the competitors’ price, will be displayed on the site in a different color at the end of the auction. Also, customers and all participants will receive a notification about the appearance of the ANC in the procurement. After that, a participant with such a price must justify the regulatory authorities the price set by him. In case of failure to fulfill such an obligation, his proposal will be rejected.

Some fear: what if a customer deliberately accepts an inappropriate rationale? In this case, in this case, other participants may appeal the decision of the customer in the Antimonopoly Committee.
As a result, the display of the ANC in the system will greatly facilitate monitoring by the public of this kind of procurement, and will become an additional marker for participants.

• Another point of the new law is the personal responsibility of officials for violation of the law in the field of public procurement. This innovation provides a fine of 2,000 to 10,000 tax-free minimums (34-170 thousand UAH.). So how can an official “fine” to get the minimum and maximum punishment?
Recall that previously there was such a thing as a “tender committee”, which included employees of the customer company. According to the new law, such committees will be liquidated from January 1, 2022, and the “authorized person” – specially trained people who will organize and conduct the procurement will be responsible for the procurement. It is these people who will now be responsible and punished with fines for violations of the law, the size of which will be determined by the authorized bodies.

• The document also says that now complaints can be submitted to the AMCU through the ProZorro system. Will it reduce at least some component of corruption schemes?
First of all, such an innovation is aimed at facilitating the work of participants by saving time. After all, now they no longer need to collect a huge list of papers that they will send to the AMCU, it will be enough to draw up an electronic document and pay for the complaint.
However, of course, this has to do with reducing the corruption component in public procurement, due to the dependence of the cost of filing a complaint on the cost of procurement.

• And finally, ProZorro.Market – the so-called online store for budgetary institutions, involving the introduction of electronic catalogs of common goods. How will he act?
By the principle of work, it will resemble an online store: suppliers publish their goods in the catalog, and customers, comparing for a particular product, will choose the best prices and conditions. The advantage of this innovation is that customers and participants do not need to spend time each time accepting offers, auctions, signing contracts for a long time.

As for the other changes, our specialists have studied them in more detail and are ready to share with you the advantages of various innovations. You can contact our legal department by filling out the form below:

How to make the Internet safe? Google Chrome will soon block downloading files via HTTP

A few years ago, Google began to consider HTTPS support when ranking search results with indexing of HTTPS pages by default. Soon, in the Chrome browser (from version 68), pages using the HTTP protocol began to be flagged as insecure. The next step taken to improve Internet security was to block file downloads without encryption.

Recall that in October 2019, the Chromium development team first announced the appropriate mechanism to combat the so-called “mixed” content and warned that blocking would be introduced gradually. What does “mixed” content mean? This is when on HTTPS pages individual elements are insecurely loaded via HTTP without encryption. This process was officially launched in Chrome 80.

In addition, the Google development team has published a plan to introduce in Chrome a new mechanism for blocking file downloads over HTTP. The improvement should increase the security of users on the Internet. As the developers explain, downloading files without encryption can be used by cybercriminals. They can intercept sensitive data through content spoofing during MITM attacks.

chrome_version_timelineIn the current version of Chrome 80, automatic updating of “mixed” audio and video content is enabled when possible. Also, corresponding notifications about mixed content appeared on the page for users – they will be displayed in the Omnibox line.

With the release of Chrome 82, the browser will start to warn you every time you try to insecurely download executable files using links from HTTPS pages. In Chrome 83, blocking for executable files will already be enabled by default, and warnings will be displayed for archives.

With the release of Chrome 84, the lock will extend to archives, and if documents are uploaded, the system will warn of potential dangers.
In Chrome 85, documents will also be blocked, and warnings will start to appear when unsafe downloading of images, videos, sound, and text that starts to block with the release of Chrome 86.chrome-http-download-blocked

In the mobile versions of Chrome for Android and iOS, blocking will be implemented with a lag of one release (warnings will appear not in Chrome 82, but in version 83, etc.). In Chrome 81, an option will appear in the service settings section that allows you to enable the display of warnings one release earlier. It is already available in the test version of Chrome Canary.
