References Introduction: This paper is going to take a look at what goes on inside our computers and explain what the components are and how they function. For most people, getting inside a computer is something they would not even think about. Its probably best that most people feel this way. However, for†¦show more content†¦How does the computer know if an error has occurred? Detection is accomplished by use of a parity bit. A parity bit, also called a check bit, is an extra bit attached to the end of a byte for purposes of checking for accuracy. Parity schemes may be even parity or odd parity. In an even-parity scheme, for example, the ASCII letter H (01001000) consists of two 1s. Thus, the ninth bit, the parity bit, would be 0 in order to make an even number of set bits. Likewise, with the letter O (01001111), which has five 1s, the ninth bit would be 1 to make an even number of set bits. The system software in the computer automatically and continually checks the parity scheme for accuracy. Machine Language: Your Brand of Computer’s Very Own Language So far, we have been discussing how data is represented in the computer, for example, via ASCII code in microcomputers. But if data is represented this way in all microcomputers, why won’t word processing software that runs on an Apple Macintosh run (without special arrangements) on an IBM PC? In other words, why are these two microcomputer platforms incompatible? It’s because each hardware platform, or processor model family, has a unique machine language. Machine language is a binary programming language that the computer can run directly.

To elaborate, the stored program concept provides two beneficial functions that modified the design of computers. First, computers would have the ability to signal and store programs and data in the same ROM or RAM (Sharma, 2015). By viewing programs as data and vice versa, theRead MoreApplication of Assembly Language922 Words   |  4 PagesAssembly Language is used when speed and reliability are the overriding factor like small footprint real-time operating systems. 2. By using assembly language, programmers can maximize on speed to a level. It is easy to write than machine code programs. 3. It allows the programmer access to registers or instructions that are not usually provided by a High-level language. 4. The main Application of Assembly Language is for direct hardware manipulation i.e. device drivers. 5.

What do you think are the main advantages of specifying a computer-based system by means of such a structured specification? How adequately, do you think, does this method deal with the human aspects of information systems changes? According to DeMarco’s structured analysis, it is a study of a problem leading to the specification of a new system prior to implementation of that system. DeMarcoRead MoreDisadvantages Of Artificial Intelligence964 Words   |  4 Pagesdangers and fully utilize it for global benefit. Artificial intelligence is the future. This is a fact. Since 2015, with the invention of deep learning methods, we, as a civilization are moving towards true AI. Artificial intelligence, depending on how its harnessed, could be a blessing, a curse, or both. On the upside, Artificial intelligence would allow us to achieve more than ever before. On the downside, however, Artificial intelligence could take away millions of jobs and possibly even developRead MoreRole of Computers in Healthcare1650 Words   |  7 PagesTopic: The Role of Computers in the Health Sector There have been many innovations and inventions since the civilization age and the industrial revolution that took place in the eighteenth century and has continued till present.
