I analyzed chapter 1 of the book and in short will briefly go over some of the key terms. First is the concept behind bits and bytes. Bits represent the concept of a binary digit. Computers record the ideas they work with electronically as bits and represent either a 1 or 0. Bytes are equivalent to 8 bits. Some tasks require only a few bytes of data, others require the computer to actually organize data into groups of thousands or millions of bytes. Computers use binary math based on powers of two. RAM (random-access memory) uses an address for each unique memory location where a byte can be stored. It is only temporary memory and will erase data once the computer is shut down. Text characters are stored in RAM as bits by the CPU. For each letter pressed on the keyboard, hidden to the user, the keyboard sends some bits to the computer. The CPU’s filing system organizes files through file concept which lets the CPU treat all the bytes in one document, one song, one video and so on as group of bytes that be refreshed as a name.
Disk drives organize the storage locations based platters, tracks, and sectors. The CPU writes the file to a disk by identifying some unused sectors, the CPU must mark these sectors as used. As a result the platter, track and sectors have to be recorded and noted as holding contents so that file contents so that can file contents can be found later. Hard disk store data using magnetic using magnetic charges applied to the surface of a platter.
The mouse sends binary codes to the CPU using a signal and the CPU has a map that shows
