DATA ORGANIZATION PRE-READING ACTIVITY Answer the following questions orally: 1. What is data organization? 2. Do computers work with a specific code? 3. Are there different code types? BITS Read the text that appears on the link’s section and answer T or F. There is not a wide variety of items people can represent with a bit People can represent finite binary data types Bits always represent the same. Bits are not so important in programs. CLICK HERE TO SEE THE ANSWERS CONNECTORS - LINKERS Go to the text again and search for: • Which is the structure the author use to contrast two ideas? ____________________________________________________ • Is that word or phrase repeated in the rest of the text? ____________________________________________________ • What is the notion of that structure? ____________________________________________________ • Do we always have to use it at the beginning of a sentence? ____________________________________________________ CLICK HERE TO SEE THE ANSWERS SYSTEMATIZATION EXAMPLES • However, you can represent only two different values with a single bit. • However, since everything else consists of groups of bits, bits will play an important role in your programs. • However, you will soon see that individual bits are difficult to manipulate, so we'll often use other data types to represent boolean values. NOTION: contrast RULE: However, … ….., however, … ACTIVITY 1 Create new sentences in a Word document using “however” with the information provided below. Then, upload the archive to the “LESSON 1” page on the wiki with your surname as the name of the archive. 1. In pure mathematics a value may take an arbitrary number of bits. Computers generally work with some specific number of bits. 2. You may get the impression that there are a very small number of items you can represent with a single bit but there are an infinite number of items you can represent with a single bit. 3. In information theory, "one bit" is typically defined as the uncertainty of a binary random variable that is 0 or 1 with equal probability, whereas in quantum computing, a quantum bit is a quantum system that can exist in superposition of two bit values, "true" and "false". 4. A bit is usually represented by an electrical voltage or current pulse. But it can also be represented by the electrical state of a flip-flop circuit.
