I got a preliminary understanding of the structure of the board today after I went through the datasheet of the Raspberry Pi. It included many components with different functions, which made up a small computer system. CPU (Central Processing Unit) The Raspberry Pi uses BROADCOM for its CPU and the model number it used was […]
My raspberry PI has finally arrived✌🏻! I opened the outer box and checked the board out. I also bought a Raspberry Pi Hat along with it. It is an extension hardware that can greatly improve the learning capability and playability of the Raspberry PI by connecting with 40 GPIOs.
Through two years of studying computer science in high school, I had a basic overview on the knowledge about software, hardware, and network. For example, I learned about the basic structure of the CPU (Vonnewmen’s architecture) and programming languages (python). These information are all theoretical knowledge, even though they are very useful and important, it is […]
Find the Nth Number in a Sequence In any sequence, if you know the nth term rule, you can find any term in that sequence. Remember, n stands for the position of the term: for the 1st term, n = 1; for the 10th term, n = 10; for the 1765th term, n = 1765. We simply substitute n into the nth term rule for our quadratic sequence. To […]
Greatest Common Factor: To find the greatest common factor of two number, you can use a method called short division. Short division is done firstly finding the factors of each number, then the common factors, and finally the greatest common factor among the common factors. But the problem of short division is: when the common […]
Problem: Find all prime numbers within a given range n A prime number is a positive integer that has no positive integer divisors other than 1 and itself. There are a lot of ways to print all the prime number within range n. Method 1: The most direct method is to start from the definition. For […]
The abbreviation of RSA is Rivest–Shamir–Adleman, which is the name of three people.Rivest along with Shamir and Adleman are the inventors of the RSA algorithm. How does RSA work? An RSA user creates and publishes a public key based on two large prime numbers, along with an auxiliary value. The prime numbers are kept secret. […]
