Do you know the correct answer? Today, a very important article, especially for beginning electrical designers, since not everyone has studied in their specialty and may not have this information. We are not talking about the letters “I”, “L”, “I” at all, as it might seem at first glance.
When designing automation, and even power supply, it is necessary to develop various control schemes using control contacts. It is in such cases that we use the logical chains “AND” and “OR”. I will show the distinctive features with examples.
The elements connected in series form a logical “AND”, i.e. the event (on/off) will occur when each event in our chain is fulfilled.
The simplest case. Let's take two switches and a light bulb.
When connecting switches in series, the light will light only if both switches are turned on.
I use logical “AND” when connecting fire dampers, i.e. so that the fan does not turn on until the valves open.
Parallel connected elements form a logical “OR”, i.e. the event (on/off) will occur when at least one element from our scheme is executed.
The same example with a light bulb.
Logical "OR"
In this case, the light will light up when any of the switches is activated.
This connection is often used if you need to turn on/off the engine (pump, fan) from different places. Fire hydrant buttons are connected to each other in parallel.
“I like” and “I”d like” - “I like” and “I would like.”
"What does Ann like?" - “What does Anna like?” "What is Ann like?" - "Tell me about Anna."
1a) " I like coffee" - “I like coffee.” I like grapefruits. I like travelling. Here like - verb, it translates as “to love.”
1b) " What does Ann like?" - "What does Anna like?" Here like - verb, it translates as “to love.” We understand this because the auxiliary verb in the question is "does".
2) "I"d like some coffee" - “I would like coffee" (“I”d” means “I would”, in colloquial speech we always shorten it).
Please note that after " I like"we say verb in -ing form(I like traveling- I love to travel), and then " I"d like" - first form verb (I"d like to travel around Russia - I would like to travel around Russia.)
3) "What is Ann like?" - "Tell me about Anna" (literally: "what is Anna like?"). Here like - adjective, translated "similar to". We understand this because the verb in the question is "is".
More examples:
- "I don"t like cooking" - "I don't like cooking" (case 1a)
- "Why don"t you like hamsters?" - "Why don't you like hamsters?" (case 1b)
- "I"d like to visit Italy again" - "I would like to go to Italy again" (case 2)
- “He isn’t like his father” - “He doesn’t look like his father.” (case 3)
- "I really like white coffee" - "I really like coffee with milk" (case 1a)
- "Do your parents like living in the country?" - “Do your parents like to live outside the city”? (case 1b)
- "Would you like some more wine?" - “Would you like some more wine?” (case 2)
- "Is Berlin really like Boston?" - "Is Berlin really like Boston?" (case 3)
Translate to English:
- I wouldn't like coffee right now. I'd like some tea.
- What is the island of Tenerife like?
- Do your friends like to live in the countryside?
- Would you like to watch this film again?
- English films are not like American ones

In the 21st century, it is impossible to imagine the Internet without websites and blogs. However, what are the important differences between both resources to note? How are they different from each other?
Designations: website, blog
A website is any Internet resource that is initially located on the World Wide Web. Thus, a variety of portals, virtual stores, blogs and news resources fit the definition. It should be noted that the word site appeared thanks to the English language, and it was originally translated as “place”, therefore it is possible to count on the fact that the resource will be a special place owned by the webmaster and allowing it to successfully search for site visitors to increase traffic. Taking into account such aspects, it should be noted that a blog is a type of website. 
What could be an accurate and complete definition for a blog? First of all, it should be noted that any website is required to convey information to the target audience. However, resource owners usually do not tell personal information and do not share events that they experienced, and do not seek to establish contacts with the target audience. At the same time, bloggers should not only share knowledge on a certain topic, but also talk about their lives. A blog is a kind of virtual diary of a person, and absolutely every visitor can get acquainted with the information. 
However, in order to understand what the main differences and similarities of a blog site are, you need to further consider the topic.
Differences between a website and a blog
- Basic Concepts. A website is a place on the Internet. A blog is a virtual diary or journal. Thus, a blog is a type of website that has certain features.
- Home page. The main page of a blog can be compared to a news feed, with the latest topic positioned above the others. With the update of the information structure, a gradual movement of materials is expected in chronological order, and only announcements with thumbnail images can be displayed on the main page.
- The site is static and permanent. For this reason, new publications may only be appendices to existing sections and categories. Articles must fall into the overall structure of the project.
- Dynamic categories. The blog has dynamic headings, sections, categories, the scheme of which is always based on the published news.
- Author - administrator. The blog should be developed by one person, who will always write only in the first person. Thus, the author of the blog simultaneously turns out to be its administrator, optimizer, manager, webmaster, and not just the owner. However, recently public blogs have appeared, so gradually this difference begins to fade into the background, since it does not always manifest itself as clearly as it could.
- Comments. Blogs have a unique form of commentary, which is ideal for live communication with representatives of the target audience. Moreover, for communication you can use a special form located under the text of the article. On websites, articles should have a finished appearance; on blogs, they should be subject to active discussion in order to receive comments.
- News feed. On traditional sites, subscription is in most cases implemented through a special form, on blogs - using an RSS news feed, which is a mandatory attribute of the resource. At the same time, the RSS feed allows you to receive automatic messages by email about the addition of new notes, comments, and actively monitor any changes.
- Static resources involve automatic distribution of messages or news (like RSS). Pre-compiled texts of letters, which are written separately, may contain advertisements and unique offers, which is typical for blogs.
- Update frequency. Blogs should be updated more often than websites. Only in this case can a blogger successfully maintain constant contact with the target audience, talking about thoughts and ideas, and various observations. The main goal is to provide personal opinions and up-to-date information. The blog author must have authority and demonstrate his knowledge and skills.
Blogs must present information in a special way to successfully interact with the target audience:
- It is expected that articles of an interrogative nature will be published.
- There is a need to describe controversial thoughts for active discussion.
- Readers must be addressed directly.
- There is an opportunity to highlight the author's position.
The main task of any blog is to develop live communication under published articles.
Similarities between a website and a blog.
- A domain name is required.
- Any Internet resource needs hosting.
- The site and blog are always publicly accessible.
- The content necessarily contains text, pictures, videos, links, audio.
- A mandatory thematic focus is expected.
So, a blog is a type of website, and it is supposed to be aimed at communicating between the author and the target audience.
This article provides a small comparison of i3 i5 i7 processors. Typical tasks for all Core series processors will also be briefly described. The names of Intel processors vary so much that the average user will not understand what one or another processor name means. Of course, in itself it carries its own meaning, but at first glance, it is a confusion of abbreviations and numbers.
Before purchasing a new processor from Intel, a reasonable question will arise: what is the difference between i3 i5 i7 processors. To understand all this, we can divide all Core processor names into two groups. The first, most interesting for us, is the line (i3/i5/i7). We will focus our attention on it. The remaining part of the name, including numbers and letters, shows us the distinctive features of a particular processor, which we will consider below.
There are a couple of main features in the Core series. The socket (socket for installing a processor) in the same generation will always be the same. You will not need another motherboard for the same Core i3, unlike i5 or i7. All processors have a built-in graphics core. The sixth generation Skylake we are considering uses 1151 sockets and integrated HD530 graphics.
Core i3
Even though i3 processors are the least powerful among the Core processor series, they are an excellent choice for everyday tasks. They have two physical cores, but Hyper-Threading technology smooths out this drawback. Hyper-Threading doubles the available processor threads by emulating 4 "virtual" cores. The L3 cache capacity reaches 3-4 MB, depending on the specific model, and frequencies vary from 2.7 to 3.9 GHz. You can buy a processor for 110-140 US dollars.
He can do everything a little, but he can’t do anything perfectly. The performance of these processors is enough to make the system responsive, but heavy tasks like rendering or video editing will be a pain on them. They are fast enough to drive a modern graphics card, so they can be used on entry-level gaming systems with an average graphics card.
Core i5
Sitting exactly in the middle between the i3 and i7 lines, the i5 line of processors have many of the latest features with pretty good power efficiency. This series lacks Hyper-Threading technology, but has 4 physical cores, Turbo Boost, and processor models with an unlocked multiplier for overclocking. The amount of L3 cache reaches 6 MB (in i5 desktop models).
Turbo Boost allows the processor to temporarily increase the frequency of one or more cores under load, at the expense of increased power consumption and reduced processing power of other cores. In essence, this technology is a kind of overclocking of the physical core. Sixth generation i5 frequencies range from 2.2 to 3.5 GHz, and prices range from $180 to $220
Core i7
At the top are the i7 line of processors. They have four logical cores, like in the i5 line. Hyper-Threading is also present, creating as many as 8 threads on 4 physical cores. These processors have the highest frequencies, reaching 4 GHz by default and 4.2 GHz in Turbo Boost. i7s come with 8 MB of L3 cache, and you can purchase a processor in this line for prices ranging from $300 to $340.
Although these processors are endowed with the highest performance, this is clearly more than enough for the average user. It is the processors of this line that will allow you to see by eye how the i3 i5 i7 processors differ. i7 processors are great for programs that can take full advantage of all 8 threads. Despite this, many games to this day use only 4 cores. Even Photoshop benefits from working with more than 2 cores only when special filters and operations are used. If you don't work in Maya and Autodesk on a regular basis, you will see virtually no increase in how the i3 i5 i7 differ in simple tasks.
Index values
A processor from any manufacturer has its own indexes, located in the remainder of the name after the manufacturer and product number. The higher the product ID, the more powerful the processor usually is. Letters T, U And Y denote processors designed for low power consumption. Letter K at the end indicate processors with overclocking potential, and P indicates the presence of a less powerful graphics core. If you want a more detailed description of the indexes, take a look at the Intel website.
What to buy?
Without going into all these designations, we can say that Core processors make it easy to determine which one is best for you. This can be seen even from one symbol in the name of the line. The difference between i3 i5 i7 is the processing power. Another difference between i3 i5 i7 processors is the graphics core. In i5 and i7 it is usually the same, but in i3 it is weaker. Unfortunately, not all users think about how the i3 i5 i7 differs and choose a processor whose capabilities are simply not used, or vice versa.
Most users will be happy with the i5, which offers a good price-to-power ratio. The i3 will still be an excellent choice for budget builds; it is a good option for the money. If you are confident that your processor will be tasked with heavy tasks such as rendering or editing large video files or modeling, then the capabilities of the Core i7 will completely satisfy you.
I think this article has clarified how i3 i5 i7 processors differ. I hope this information will play a role in choosing a particular processor when purchasing.
