In this activity you will learn how to convert numbers between the decimal, binary, octal, and hexadecimal number systems.…
For example, the capital letter A is ASCII character 65, the numeral 2 is ASCII 50, the character} is ASCII 125 and the metacharacter carriage return is ASCII 13. Systems based on ASCII use seven bits to represent these values digitally. In contrast, most computers store data in memory organized in eight-bit bytes. Files that contain machine-executable code and non-textual data typically contain all 256 possible eight-bit byte values. Many computer programs came to rely on this distinction between seven-bit text and eight-bit binary data, and would not function properly if non-ASCII characters appeared in data that was expected to include only ASCII text. For example, if the value of the eighth bit is not preserved, the program might interpret a byte value above 127 as a flag telling it to perform some function. It is often desirable, however, to be able to send non-textual data through text-based systems, such as when one might attach an image file to an e-mail message. To accomplish this, the data is encoded in some way, such that eight-bit data is encoded into seven-bit ASCII characters (generally using only alphanumeric and punctuation characters—the ASCII printable characters). Upon safe arrival at its destination, it is then…
2.Convert your binary result back into decimal to prove your answer is correct. This is also…
What is data redundancy, and which characteristics of the file system can lead to it?…
1. A striped volume writes to the physical disks evenly, rather than filling allotted space one and then moving to the next, and striped volumes do not provide fault tolerance.…
c) There was no overflow condition because the numbers have opposite signs and overflow cannot occur.…
From the first look at the CourseMate recourses, user will find a number of very intelligent tools that can help him/her to read, practice, and even taking some quizzes to evaluate his/her level.

11. Given 4 bits of mask for the network portion, how many subnets are available?…
Chapter two discusses the understanding of computer, math, and measurements. Also, it shows you how we use computer math with computer hardware and systems. Some of these concepts are bits versus bytes, binary versus decimal, Boolean operators, hertz, and data transfer. The chapter two also shows numbering systems used in computers. These are some importance skills that will help you in the computer field.…
