A computer network is made up of two or more computers or other intelligent devices connected by communication media (eg, cable or wireless media) to achieve communication. The network computer is used in many aspects of our lives and its applications are growing. Computer networks can be found, for example, at universities, secondary schools and colleges of higher education, while in the business community networks are networks at geographical locations. Government offices use local and state computers, such as military organizations, medical facilities and the internet. The frequency of computer network attacks and the subsequent burning of news reporting has alerted the public to the vulnerability of computer networks and the risk of not only using them, but also of being dependent on them. Moreover, such activities and reports put society in a state of constant fear that always anticipate the next big and what is involved, and force people to focus on security issues. The bi...

Multiprogramming has become possible when the disks are introduced into the computer world. The concept of multiprogramming depends on the ability of a computer to store instructions for long-term use. The goal is to reduce the CPU time inactive by allowing new tasks to grab the CPU when the current active task has to wait (eg for user I / O). It is also at this moment that the operating systems have been given a new responsibility - decision-making. Before multiprogramming is introduced, the role of the operating system is simple and uncomplicated - to load and run a memory program via the CPU. With the advent of multiprogramming, operating systems are confronted with different program implementation mechanisms because many tasks now have to be loaded into memory at the same time and there are many options to take the CPU time. In one or more programming systems, one or more programs are loaded with basic memory ready to be performed. A program at the same time This ensures that t...

Questions that are open-ended provide rich qualitative data. In essence, they provide the researcher with an opportunity to gain insight on all the opinions on a topic they are not familiar with. However, being qualitative in nature makes these types of questions lack the statistical significance needed for conclusive research. Nevertheless, open-ended questions are incredibly useful in several different ways: 1) Expert Interviews Since questions that are open-ended ask for the critical thinking and uncut opinion of the respondent, they are perfect for gaining information from specialists in a field that the researcher is less qualified in. Example: If I wanted to learn the history of Ancient China (something I know very little about), I could create my survey for a selected group of historians whose focus is Ancient China. My survey would then be filled with broad open-ended questions that are designed to receive large amounts of content and provide the freedom for the expert t...

The weight of a body is 147 N. What is its mass? (Take the value of g as 10ms -2                  W= 147N m=? g= 10 m 5 2 W= mg m= 14.7 kg

A force of 20 N moves a body with an acceleration of 2 ms -2 . What is its mass?              F= 20N a= 2ms -2 m=?   F= ma m= 10 kg

Machine language programming is very difficult and complex. In their search for more appropriate programming languages, programmers started using some mnemonics for each machine instruction and this language was called assembly language. These reminders are finally translated into the machine language for implementation. Programs called assemblers are written to automate the assembler translation of the machine language. The input for the assembler program is called the source program and the machine language output is called the object code. An assembler is a program that accepts a language conference program as input and makes the equivalent of its machine language along with the information for the loader. Assemblers are similar to interpreter, except that each language instruction is translated into a machine instruction. In each interpreter the instruction is translated into many instructions. The assembler takes less memory space on a computer and works faster than the inte...

The interview is a method of inquiry characterized by the fact that oral inquiry is used as the most important method for collecting data. Interviews are used by people in everyday life, but as a scientific tool for social research, or better as a means of collecting data, communication is different from implementing, building and implementing the awareness prepared and implemented in a systematic way. Interviews are largely composed of questions, listening to individuals and recording their answers. Interviews allow participants to provide rich, contextual description of events. Interviews are a systematic way of communicating and listening to respondents and another way to collect data from individuals through conversations. Kvale (1996) recognizes interviews as "an exchange of views between two or more people on a subject of mutual interest, recognizing the central area of ​​human contact for production of knowledge, where the context of social research data. "...

In this way, the interviewer personally meets the information and asks them the necessary questions about the subject of research. Usually a series of questions or a questionnaire he brought and the questions were asked. The interviewer is efficiently collecting data from informants by cross-examining them. The interviewer should be effective and tactful to obtain correct and relevant data from informants. Advantages of interview are following: Ø   Flexible and high response Ø   Easy management and ability to observe non-verbal behaviors Ø     Control the environment and order questions Ø     Ability to correct disputes by respondents: such options are very important and are not available in other ways of collecting data. Ø     Opportunity to record natural responses Ø     Control the time, date and place of the interview Ø     More complex questions can be used because the presence of the interviewer can ...

•       It must look easy, attractive and interesting. •       Keep it as uncomplicated as possible. •       Clarity of wording. •       Simplicity of design. •       Simple, short and clear instructions for completion. •       Avoid placing instructions at the bottom of a page. •       Break down long lists of numbered items into separate sections, each item in the section starting with the number ‘1’. •       Make it clear if respondents are exempted from completing certain questions or sections (filter), and where they go next if they are exempted. •       Include a preliminary statement of anonymity/confidentiality. •       Place response categories to the immediate right of the text.

Closed-ended questions can be further classified into several types. 1. Leading Question Questions that force your audience for a particular type of answer are known as leading questions. In a leading question, all the answers would be equally likely. An example of a leading question would be a question with choices such as, fair, good, great, poor, superb, excellent etc. These questions are meant to get an opinion from the audience in limited words. Example of a Closed-Ended Leading Question How would you rate the quality of Nokia phones Excellent great good fair poor 2. Importance Questions In importance questions, the respondents are usually asked to rate the importance of a particular issue, on a rating scale of 1 to 5. These questions can help you understand things that hold significance to your respondents and allow you make business critical decisions. Example of a Closed-Ended Importance Question The use of GTM in pakistani school systems is Ext...

Successful completion of a sampling procedure involves researching the respondents and defining nature and the number of respondents involved. The researcher knows this stage not only what is being studied, but also who he needs to access for the necessary information. The information is available, make available the correct relationship between the researcher and the respondents is made. Research tools are provided on subjects for the collection of verification or data. Most educational research will lead to the collection of data through a number of standardized test- or self-constructed research tools. It must provide objective data for the interpretation of the results achieved in the study. The data can be obtained through questionnaires, tests, personal observations, interviews and many other methods for collecting quantitative and qualitative evidence. Researchers need to know how much and what type of data collection will take place and when. He must also ensure that the...

There are many kinds of interviews, each of which is different from the structure, purpose, interviewer's role, the number of respondents involved in each interview, and the form and frequency of supervision.     1.       Structured interview A structured interview is sometimes referred to as a standardized interview. The same questions are requested by all respondents. Structured interviews are "interviews where all respondents are asking the same questions with the same words and the same questions with the same words and the same order." The goal is that all interviewees will receive the exact same context of the inquiry. The strengths of structured interviews are that intermediaries have control over topics and interview formats. Conversely, the disadvantages of structured interviews are very close to the interview guide and may result in inactivity of relevant information.     2.       Semi-structured In...
