Technical Support Fundamentals: How to Count in Binary WK 1

Technical Support Fundamentals: How to Count in Binary WK 1 Which of these is a valid byte? Check all that apply. ; A byte is composed of eight bits of zeros and ones. ; A byte is composed of eight bits of zeros and ones. How many possible values can we have with 8 bits? 256; Bits use the binary system, which is also known as the base-2 numeral system. So 2^8 allows us 256 values from 0 to 255. Why did UTF-8 replace the ASCII character-encoding standard? UTF-8 can store a character in more than one byte; UTF-8 replaced the ASCII character-encoding standard because it can store a character in more than a single byte. This allowed us to represent a lot more character types, like emoji. What is the highest decimal value we can represent with a byte? 255; There are 256 values in a byte, from the decimal number 0 to 255. The binary value of the ASCII letter "c" is . Using the handy chart that we learned in the lesson, convert this number to its decimal value. You'll need to use some math for this question. 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 99; The decimal value 99 is same as the binary value . So the numbers that are turned ON are 64, 32, 2, and 1 and added up together. In other words, 64 + 32 + 2 + 1 = 99. What are the four layers of the computer architecture? Hardware, operating system, software, user; The layers of computer architecture are the hardware, operating system, software, and user layers. Write a paragraph on examples of abstraction that you encounter in your day-to-day life. For example, driving a car is an example of abstraction, you don't need to understand how a car works underneath the hood in order to drive one. In a computer, I would need a keyboard and a screen in order to work with the hardware and its operating system.; It's amazing how often we use abstraction in our daily lives, without even realizing it. Thank you for submitting your response to this prompt. I encourage you to think of other ways you use abstraction in your daily routine. This habit will help as you prepare to become an IT Support Specialist!
