Converting binary numbers to other number systems

A binary digit is called a bit . The binary number system is the main system for representing information in computer memory. For more information about the mathematical tools and operations, please visit CoachingSelect.  Converting binary numbers to decimal Acceptable, given a binary number 1100012  To convert to decimal, write it as a sum over the digits as follow                                     1.25 + 1.24  + 0.23 + 0.22 + 0.21 + 1.20 = 49. Same thing a little different:                                          1.32 + 1.16 + 0.8 + 0.4 + 0.2 + 1.1 = 49. You can write this in tabular form as follows: 512 256 128 64 32 16 8 4 2 1         1 1 0 0 0 1         +32 +16 +0 +0 +0 +1 Move from right to left. Under each binary unit, write its equivalent on the line below. Add the resulting decimal numbers. So the binary number 1100012 equals decimal 4910. To convert from binary to decimal, use the following table of base 2 powers:  1024 512 256 128 64 32 16 8 4 2 1   Converting from binary to octal and hexadecimal number systems If you need to translate directly between binary and octal, binary and hexadecimal number systems, you can use a special scheme for quickly converting numbers. In this case, the following rules are used: each octal digit can be written as three binary ( triad ), each hexadecimal digit can be written as four binary ( tetrad ). If the number of binary digits is not a multiple of three (four), then the number is optionally padded with insignificant zeros on the left. Use an online binary code translator to translate binary numbers into characters easily and quickly.  Table of octal numbers:           X10               X8                            X2 0 0 000 1 1 001 2 2 010 3 3 011 4 4 100 5 5 101 6 6 110 7 7 111   Hex table:            X10                  X16                            X2 0 0 0000 1 1 0001 2 2 0010 3 3 0011 4 4 0100 5 5 0101 6 6 0110 7 7 0111 8 8 1000 9 9 1001 10 A 1010 11 B 1011 12 C 1100 13 D 1101 14 E 1110 15 F 1111   Converting binary fractions to decimals Need to translate a number 1011010, 1012  to the decimal system. Let's write this number like this-                  1.26+ 0.25  + 1.24 + 1.23 + 0.22 + 1.21  0.20+ 1.2-1  + 0.2-2 + 1.2-3 = 90,625. Or according to the table: 64 32 16 8 4 2 1 0.5 0.25 0.125 1 0 1 1 0 1 0 1 0 1 +64 +0 +16 +8 +0 +2 +0 +0.5 +0 +0.125

How Check Plagiarism Helps Students in Detecting Plagiarism

However, we will do all of that with a special focus on students, and whether this tool can help them to detect plagiarism in their writing. We will also discuss the pricing and recommend the best packages for students. For more assistance in studies, you can visit CoachingSelect.  It will also help you decide whether you should use this plagiarism checker over the many others available online. At the end of this review, you will have no confusion or misconceptions regarding this tool. Check-Plagiarism Overview It is important to note that Check-Plagiarism is a platform and not a tool. It provides a multitude of content optimization tools such as a paraphraser, summarizer, and grammar checker. However, these tools will not be discussed in this review as it is limited only to the plagiarism checker. We will start by discussing the plagiarism checker’s appearance and how its navigation works. Let’s get into it. Appearance and User Experience Features: 1. Appearance When you first visit the webpage, you are greeted with the following screen. Except it will look slightly different if you do not have an account. For the purpose of this review, we are using a premium account so that we can check out all of its features. The first thing we can see is the obvious text box with some graphics in it. This is the input field. Users can enter their content into this box in two ways. They can either type or copy-paste their content into it manually. Or they can click the “Upload Files” button to browse their device to locate a file and upload it. So, for appearance, our conclusion is that it is quite simple, and uses that simplicity to its advantage. The advantage is that this tool is very easy to navigate and new users can easily figure out what to do when they visit the page. 2. Accessibility Students are always worried about the accessibility of the tools they use, and that’s because they do not have the financial power to use expensive tools. Check-plagiarism is a very student-friendly tool because it is freemium. That means that it is available for free but has some limitations on its usage. Be advised that this is not some kind of trial period where you can use the tool a set number of times. It is actually free and has very generous usage limits. Free users can check up to 1,000 words per session, and there is no limit to the number of sessions. And the best part is that the free features can be used without an account as well. So, students do not have to worry about giving out their email and registering. 3. Multiple Language Support This tool is not limited to English. Users who speak multiple languages or are from foreign countries can switch to their language and use the tool. There are 14 languages supported including English. Most of the languages are European such as German, French, and Spanish, but other languages are available too. The best thing is that this feature is not limited to the premium version. All languages are available in the free version as well. So, Check-plagiarism is good for students all over the world. 4. File Uploading Users can upload files to the plagiarism checker. They can do this by clicking the “Upload Files” text which only appears when the input box is empty. It allows users to open a window and browse their device to find the file they want to upload. The supported formats for this upload process are: DOC DOCX TXT PDF These four are the most commonly used file formats, so users and especially students will have little to no trouble when using the file upload option. Features Related to Functionality: The basic function of this tool is to check for plagiarism in the provided text, however, there are some features that can enhance or augment this function. 1. Exclude URL If you are checking some work for plagiarism that is already published, then this feature can help you out. By providing the link to the webpage where the article is published, users can exclude it from the comparison. This will ensure that no plagiarism shows up against that source. You can find the “Exclude URL” feature on the bottom right of the input box. Clicking on it opens a text bar where you can input the URL. This feature is great for reverse plagiarism checking i.e., you can check whether someone has plagiarized your work or not. 2. Deep Search This is a premium feature only and it allows the tool to conduct a more thorough search for similarities in the content. When deep searching, the tool checks pages that do not show up on the front page, or are hidden behind a complex network of links. It also allows the tool to detect paraphrased plagiarism which is quite difficult to detect. With deep search, the plagiarism checker not only matches the syntax with other sources but also matches the intent. That’s how it is able to detect paraphrased plagiarism. 3. Report Generation Once the content has been checked, the tool generates a detailed report about it. This report contains information such as the following: Degree of plagiarism Percentage of unique content A list of sources whose content was stolen Pinpoint detection of which sentences are plagiarized With this report, it is very easy to figure out whether the content is plagiarized or not. It is also helpful for students to check if their content has any accidental plagiarism. They can use the information in the report to deal with the infringing content and make their work unique. Working and Results: For the purpose of this review, we are going to test this tool by using two passages, one from our blog, and one from this article. We will check both passages and the results will determine whether it is a good tool or not. So, how does this tool work? It is quite simple. A user has to input their text into the tool and then they have to click the red button that says “Check Plagiarism”. After that, the tool starts working and compares your content against millions of online sources. Since the comparison is against such a large number of sources the output is considerably accurate. So, let’s how that looks like in action with both passages. Using Plagiarized Text First, we are going to check the passage from our blog. It should show up as 100% plagiarized. We inputted the content and that’s how it looks like: Now, we will check the content for plagiarism. The process is simple as we previously described and this is the output that we got. 91% plagiarized is almost the right result and if we check the “Matched Sources” tab, the correct source is listed as well. So, there is a little issue about false negatives, but overall, the performance is still well above the mark. Now, we will check the content with the other passage that is from this article. Using Unique Text We checked the introductory passage of this review for plagiarism. When we inputted it into the tool, it looked like this: Then we checked it for plagiarism and this is the output. It is completely unique which is the right result. So, Check-plagiarism is very accurate and does not create false positives, which makes it ideal for students. Now, let’s see its pricing plans and how affordable it is for students. Check-Plagiarism Pricing: There are four different pricing plans available for Check-Plagiarism. They range from weekly, monthly, and semi-annual to annual. The plans are as follows: As you can see the packages become cheaper the longer you have to commit. The weekly package provides the least number of words but is also the cheapest. If we look at the semi-annual and annual packages they cost less per month than the monthly package itself. Unless students have to regularly check for plagiarism, they should stick with either the monthly or weekly packages as they are the cheapest. Verdict: So, now that we have reviewed Check-plagiarism, we can safely say that it can indeed help students check their work for plagiarism. It can do that for free. The features provided by this tool are all welcome and its performance is stellar. So we give it a 9/10.

Top 10 Best Online Current Affairs Websites

Top 10 Best Online Current Affairs Websites Current affairs in simple language means "events of political or social interest and importance happening in the world at the present time" Many aspirants they see static portion and current affairs as two distinct things. But truth is that current affairs is an extension of static subjects. Why is it important to read current affairs? Current Affairs refer to the events of national and international importance relevant from competitive exams perspective like Civil Services Exam, Bank exam, etc. With the change in the pattern of examinations, questions related to current events and news have assumed a major role in deciding the fate of students. Broadly, the type of questions asked in the general awareness section can be divided into two: Static Dynamic The static portion pertains to that section of the UPSC syllabus or other exams syllabus that doesn’t change. For instance, the Revolt of 1857, the physical features of India, etc. The dynamic portion pertains to current affairs. The best bet to cover current affairs is the daily newspaper and following credible sources like Press Information Bureau (PIB) and Yojana Magazine.

It is also different from the news magazine show format in that the events are discussed immediately.

The office distinguishes Current Affairs from the coverage of news, coverage of special events like parliamentary proceedings, and the coverage of consumer affairs, among other exceptions.
