Coding & Decoding Test The class is a technique to increase IQ or intelligence. In the university admission class examination every year there is a question about IQ (Intelligence Quotient, IQ) or intelligence skills. Along with BCS Preparation, there are questions about IQ or intelligence skills in many job tests. That’s basically why we’ve created a playlist on this topic. General Knowledge + Coding & Decoding Test How is it done and the fifth episode is arranged with various tips of this test.
Coding & Decoding Test
Coding
Electronic devices like cell phones, laptops, and tablets require code to function properly. Coding allows humans to communicate with these devices. Modern technology such as traffic lights, calculators, smart TVs, and cars use internal coding systems.
Since computers do not communicate like humans, coding acts as a translator. Code converts human input into numerical sequences that computers understand. Once computers receive these messages, they complete assigned tasks such as changing font colors or centering an image. Read on to learn about how people use code to communicate with computers and develop electronic devices, machines, and other technologies.
How Does Coding Work?
Computer programming languages, developed through a series of numerical or alphabetic codes, instruct machines to complete specific actions. Computer coding functions much like a manual.
A programmer or developer writes instructions describing the information and tasks needed to create a visual or to perform a task. Computers scan extensive coded manuals very quickly, executing the tasks that create and run a successful website or application. Displaying an image or section of text, changing font styles, and opening emails all require instructions included in the coded manual.
Users interact with websites and apps with the help of these coded instructions. The code itself does not show up on the screen. Instead, people see the words and images a developer or programmer asks the computer to display.
Coding tells a machine which actions to perform and how to complete tasks. Programming languages provide the rules for building websites, apps, and other computer-based technologies. Each programming language helps humans accurately communicate with machines.
Decoding
Decoding is the process of translating print into speech by rapidly matching a letter or combination of letters (graphemes) to their sounds (phonemes) and recognizing the patterns that make syllables and words. There is an area in the brain that deals with language processing and does this process automatically.
Unfortunately, about 30 percent of students do not access this part of their brain and therefore must be taught decoding strategies very explicitly and systematically, meaning that we start with the simplest sound/letter concept and build to the more complex. This method of phonics instruction has been proven to be the most effective in helping students gain decoding skills.
Explicit, systematic and multi-sensory phonics instruction produces effective decoding skills. Phonics can be taught both implicitly or explicitly. Implicit phonics begins with a whole word and then looks at beginning sounds, ending sounds and context clues. Explicit phonics does the reverse by building from a single letter to a word. Because of poor results with implicit phonics, phonics instruction has been given a negative connotation—phonics is not really effective unless it is taught explicitly and systematically.
Phonics taught any other way could be compared to an alphabet soup of sounds. The way it is taught is what determines the level of success, particularly for those with learning disabilities such as dyslexia.
Presenting phonics and instructing it in a logical sequence, in which one concept builds upon the next, is another essential component of teaching phonics and decoding. This systematic approach helps students master skills quickly and move to the next concept seamlessly.
Teaching phonics using a multi-sensory approach reaches all learning styles in a classroom and gives those struggling readers the visual and hands-on instruction they need. When phonics is taught according to these guidelines, students will be able to find decoding success and it will quickly become an automatic process for them.
