Describe at least three different networks (computer or data communications) which you access or interact with on an average day.
Binary data codes like EBCDIC, ASCII, or Unicode are often presented using hexadecimal notation rather than a long list of 0's and 1's. Likewise other items requiring long sequences of 0's and 1's like IP addresses to identify network location are generally presented in non- binary formats as well. Describe the relationship between a hexadecimal character and its associated binary. Describe the relationship between one octet of an IP address and its associated binary. Explain why these notations are often utilized rather than the full binary. A company noting the success of 24-bit digital audio technologies compared to earlier 16-bit digital audio technologies has decided to work on developing a 28-bit digital audio technology. Describe the type of signal conversion being utilized and what the difference in bits means. Discuss whether or not you believe this company has a good plan.
During the class, you will be characterizing a network in your home, office, or community. You need to choose that network now.
