Hardware Hardware is the name given to any part of the computer that you can actually touch. A device is an individual piece of hardware. Examples include:   keyboard   visual display unit (VDU) or monitor   floppy disk drive Describing hardware Technical specification. This is a list of its properties. It usually refers to the performance and/or capacity of the device. Performance This is a way of describing how well a device in a computer system does its job. This often refers to the speed at which it works. Capacity This is the amount of data that can be stored. Processor The central processing unit (CPU) is the part of the computer where the searching and sorting of data, calculating and decision-making goes on. Also known as the processor. Choosing a processor Processors are measured by their speed. The number of instructions it can perform in 1 second. This is measured in hertz (Hz). 1 hertz = 1 instruction per second 1 KHz = 1,000 instructions per sec 1 MHz = 1,000,000 instructions per sec 1 GHz = 1,000,000,000 instructions per sec Input devices Input devices are used to enter commands or information into a computer. Examples of input devices include:   keyboard   mouse   scanner   microphone   trackball   joystick/ joypad   graphics tablet digital camera/ web-camera Output devices Output devices are used by the computer to communicate information to human users or to affect a change in a physical environment. Examples of output devices include: VDU/monitor   printer   speakers Types of VDUs/monitors cathode ray tube (CRT) liquid crystal display (LCD) less expensive to buy more expensive to buy better quality image lower quality image can be easily viewed from an angle can only be properly viewed from one angle requires more power requires less power gives off lots of heat gives off less heat takes up a lot of space takes up less space more likely to cause eye strain less likely to cause eye strain Choosing VDUs/monitors Type cathode ray tube (CRT) or liquid crystal display (LCD) (thin-film transistor [TFT]) Colour. Monochrome, or grey-scale, or colour Resolution measured in pixels; 640 X 480 (VGA), 800 X 600 (SVGA), 1024 X 768 (XVGA or XGA) Size diagonal distance, from one corner to another (inches) Types of printers inkjet laser less expensive to buy more expensive to buy more expensive to run less expensive to run relatively slow speed printing relatively fast speed printing Choosing printers Speed characters per second (cps) or pages per minute (ppm) Quality dots per inch (dpi) Colour monochrome, or colour Data storage devices Storage devices are used to store the programs and data needed by the computer. The two main categories of storage devices are main memory and backing storage. Main memory RAM random access memory RAM is used by the computer to store the programs and data that are being used at a given time. RAM is volatile which means that when the computer is turned off all its contents are wiped clean. Choosing RAM RAM is measured by its capacity; the amount of data that it can store when the computer is switched on. All computers ultimately store data as 1s and 0s (this number system is known as binary). A single unit (either 1 or 0) is called a bit. 8 bits = 1 byte 1,000 bytes = 1 KB 1,000 KB = 1 MB 1,000 MB = 1 GB Backing storage Backing storage is used to store programs and data when they are not being used or when the computer is switched off. Backing storage is non-volatile which means that when the computer is turned off none of its contents are lost. backing storage device used to read and write data onto storage media. backing storage media the collective name given to the disks and tapes used to store data. Choosing backing storage The first decision is between fixed media or removable media. Backing storage media can be measured by its capacity; bytes, or kilobytes (KB), or megabytes (MB), or gigabytes (GB). Backing storage can also be judged by the data transfer speed of the backing storage device to the backing storage media. This is measured in; bytes per second (Bps), or kilobytes per second (KBps), megabytes per second (MBps). Audio CDs read at 150KBps 8X, 16X, 24X, 48X, 52X. The final way that backing storage can be differentiated is whether it is: * read only memory (ROM), or * recordable (R)/ write once read many (WORM), or * read and write (RW). Types of portable backing storage * floppy disk drive (FDD) * compact disk (CD) drive * Zip drive * digital versatile disk (DVD) drive * flash stick Computers and peripherals Desktop computer An entire computer that sits on a desk or a table. Laptop computer A personal computer that can be simply carried around by one person and used in transit from internal battery power. Peripherals Standard (expected) Additional (extra) hard disk drive (HDD) printer floppy disk drive (FDD) scanner VDU/monitor microphone keyboard web-cam mouse (pointing device) joystick CD drive (ROM/R/RW) DVD drive (ROM/R/RW) speakers Zip drive Social Impact In the home In business P:\ICT\KS4\Yr09\Yr09Revision. 0304. doc HBDugard Page 1 of 10 Last printed 28/05/2004 14:09

My Philosophy of Education :: Essays Papers

My Philosophy of Education I believe that education should be looked as as a desire to acquire all possible knowledge, not as a requirement or something that can be formally examined by standardized tests. There are numerous ways that children learn and I want to be able to encourage as much learning as possible for each child. I believe that using many methods of instruction is the most effective way of teaching to these various ways of learning. These methods include group work, hands-on activities, buddy work, etc. Assessment of children should follow the same idea. When children get the chance to perform on different assessments, they can adequately show their strengths and weaknesses. I do not wish to rely on tests only to assess the students in my class. Some types of assessment that I think should be inlcuded in a classroom are journals, presentations, projects and interviews. I also think that the classroom should be run with the help of the children. By distributing jobs among the childre n and everyone participating in the classroom, the students will form a sense of togetherness. This will eventually create a community within the classroom. I feel that this community of learners is essential for the students to perform effectively and efficiently. They will feel comfortable in the environment and will not be afraid to take risks or ask questions. The teacher will also be a member of this community and will not be seen as unapproachable or as the only leader. The teacher should also not be seen as the facilitator of all information in the classroom. The students should be looking to other sources for information, including each other, books, and technology. There should be many points of view exemplified in each subject area. The students will be able to state their opinion and also listen to the other students' views. I believe that the curriculum should be flexible. While teaching a certain subject, if the students wish to learn about something else or move into a different idea, I want to be able to do that. I do not want to say that we aren't going to have enough time to cover something.

Recruitment and Selection Essay

DISCRIMINATION,SELF-FULFILLING PROPHECIES IN THE SELECTION-RECRUITMENT INTERVIEW Employers always want to have an interview when they want to select new personal in their company. Ofcourse, they want to be sure about new personal about that he or she does suit in their position in the company. Accordingly, interviews are important for their company in that finding right person. Therefore, it is possible to say recruitment and selection forms a core part of the central activities underlying human resource management: namely, the aquisition, development and reward of workers. Essential aspect of the interview, the social interaction occuring between interviewer and interviewee. The thesis of this paper discussing the influences which effect state of affairs during the interview according to Robert Merton’s ‘Self-Fulfilling Prophecy’. Merton is describing self-fulfilling prophecy as a ‘false definition of the situation evoking a new behaviour which makes the original false conception come ‘true’. This specious validity of the self-fulfilling prophecy perpetuates a reign of error.’ We can say that, interviewer’s bias or stereotypes might effect their initial impression about employee, according to Merton’s theory. Giving a spesific example will make it clearer; if interviewer has some stereotypes about black people, when they have interview with one of interviewee who is black, they will behave them according to their bias. Regarding this, firstly pre-interview information on the interviewee will effect interviewer’s pre-interview evaluation of the interviewee’s qualifications; secondly, first step will effect interviewer’s perception of the interviewee’s performance in the interview, then second step will effect interviewer’s post-interview evaluation of the interviewee’s qualifications; finally it will effect interviewer’s last decision on the interviewee. Consequently, it is possible to say having some bias or stereotypes cause of discrimination during the  interviews. Several studies have provided indirect support of the proposition, although they do not constitute direct test of the effects of pre-interview decisions. For instance, interviewers appear to decide on whether to hire or reject applicants before the end of the interview. The findings, however, are somewhat mixed as to just how early they make their decisions. (Springbett, 1958) Springbett (1958) found that 88 percent of the post-interview evaluations of the applicants could be predicted succesfully from pre-interview evaluation of the candidates based on their applications. Huguenard, Sager, and Ferguson (1970) manipulated the interviewer’s pre-interview impressions by providing bogus feedback from personality tests that the interviewee was either warm or cold. Regardless of whether the interview was 10,20, or 30 minutes in length, the interviewers describe the interviewees with words that were consistent with pre-interview set. The sum up, the self-fulfilling prophecy can be used for examine the discrimination in pre-interview step and having stereotypes effects all steps druing the interview. The laws prohibiting discrimination on grounds of sex, race, disability, sexual orientation and religion expressly outlaw discrimination in the process of recruitment and selection.(Daniels K., Macdonal L., 2005) Effective recruitment requires an objective, systematic and planned approach if unlawful discrimination is to be avoided. Also it is important to avoid discrimination during the recruitment process. This not only is a legal requirement, but also gives employers the best chance of getting the right person for the job. The review of articles say us, interviewer might behave to interviewee according to his or her ideas from pre-interview step, during the interview. With an example we can make it clearer, differences between amount of men employers and women employers might be result of discrimination on pre-interview step. If interviewer believe that women should take care of children at home, when interviewer has interview with a woman, he will behave to interviewee according to this idea. Interviewer might not recruit a woman for job because of concerns that she might want to start a family and she might want to have children. Also, according to self-fulfilling prophecy, when women experienced that situation more than once they might be convinced to stay at home and work in less-cost  jobs.

Relating Fiction to Real Life - 1099 Words

Relating Fiction to Real Life We read fiction not to gain new information so much as to experience the ideas and feelings a story inspires within us, and as such fictional characters can be related to real life (Kurland 1). Fiction is not real; yet, it is clear that much of fiction is inspired by or inspires those within the real world experience. In many ways, thus, fiction does reflect reality. This can be seen in Herman Melvilles short story Bartelby, the Scrivener: A Story of Wall-Street, Gabriel Garcia Marquezs Chronicle of a Death Foretold, and finally Toni Morrisons The Bluest Eye. These three stories all highlight fictional characters that reflect real world experiences of their readers. In Melvilles Bartelby, the Scrivener: A Story of Wall-Street, there are three very relatable characters. Each one of the characters represents different types of people. Nippers is a morning person, who works best in the morning. Many people would relate to this. Melville writes, in the morning, one might say, his face w as of a fine florid hue, (Melville 1). Then, there is Turkey, who I have more personal relation in the fact that the character is not a morning person, and works better later in the afternoon. The presence of these twp characters provides the two different spectrums of the situation. Thus, Melville provides both a morning and night person for his readers to relate to. On a more serious note, Bartelby can be related to some beliefs that are beingShow MoreRelatedScience Fiction : Reality And Fiction1325 Words   |  6 Pagesplayed Dr. McCoy in the classic science fiction TV Show Star Trek.
