Media literacy

Media literacy is Continuum that is verified as a line along of which people have different levels of views in term of their personal understanding of presented messages. One can develop personal media literacy during the process of intellectual, emotional and moral maturation by which he becomes able to develop individual skills and knowledge. This supports the activation of our knowledge structure so we increase the level of interpreting media points efficiently.

Passive people are considered in the lowest level of medial literacy because they only think about the outside meaning of media messages and not daring to seek better exposition. Other people are in higher rank because of their ability of relying on individual interpretation, yet they can not see what is behind the seen due to the lack of experience. However, there is different type of people who could reach a high level of media literacy and that by using all the skills and knowledge, such as the ability of using conscious process, to attain different perspective of the presented messages. Therefore, enhancing our talents and experiences will eventually aid us to improve the levels of our media literacy and become aware of the flowing message.

What are the important attributes of watching Sesame Street Program?


The first years of life are especially important in the growth and development of child's brain. Children of all ages are constantly learning new things which television could be one of the most prevalent means to influence their learning.

Sesame Street has been the most popular television show for the last four decades to the extent that this children’s show is translated to more then 19 different languages around the world. The main purpose behind this program is to aid weak young students with their readings abilities to catch up and be equally in the same level with their peers. Different characters such as Big Bird and Cookie Monster are playing important roles to attract youngster in providing humor and pleasant appearance. These features present some letters and relate them to specific words to remind the viewers about the worthiness of reading. Also, I believe that Sesame Street helps diverse children to improve their social skills and upgrade their math, English and science evaluations. Thus, the directors of sesame Street have a main role of increasing the educational level among children.

 Essentially, some regular shows of this program are presented with some songs such as “Hey Food” that sound similar to the famous Beatles’s song “Hey Jude”. This strategy makes the program always appear fresh, so the audiences feel updated through the diversity of the show. Another advantage about this television program is that there is no mention of local cultures activities which has made the program more attractive to be adapted by different families from dissimilar backgrounds.

In short, Sesame Street is an educational television program for preschool children, particularly aimed at disadvantaged children to teach them the awareness of letters and numbers.

My thoughts about motivating employees in workplace  

 In order to increase productivity of an organization, one must first fully understand what motivation is, and how the organization’s employees are motivated so that the proper incentives can be given in order to get a positive response from employees and avoid a situation of low productivity that some companies may face.

Any organization needs to understand what type of motivation their employees are inclined to, and then implement a rewarding policy to encourage productivity. If they are successful in motivating their representatives, they will begin to experience higher levels of productivity due to increases levels of job satisfaction among employees, which will also lead to lower absenteeism and turnover rates. Employers should work on resolving the main causes of dissatisfaction amongst employees rather than trying to create a sense of satisfaction through tangible rewards. Companies should consider increasing the wages of their employees, and equalizing the amount of work which is done by everybody in order to allow all the employees to feel that they are being treated fairly. The level of motivation within an organization is directly correlated to the level of productivity one has.

Operating system security issues

Computer users have largely become familiar with the operating system's accessories, such as how to play games online, but they tend to neglect the security features that are included to help the user maintain a safe and reliable operating environment. As a result, many information systems exist in an insecure state that leaves the system at risk to a virus infection or a complete compromise by an attacker. It only takes a very primitive virus or Trojan horse to create a distractive effect of infected computers and compromised systems [2]. Therefore, it's irresponsible to set up a computer (Operating System) without regard to security.

This paper is dedicated to operating system security issues. From setting up a secure home network to creating strong passwords, it's important to understand the details of using an operating system in a safe and secure manner. The aspect of security is generally defined by all of a company's data, such as the material and software resources, that allow a company to store and circulate this data [2]. The goal of OS security generally is to ensure that these organization's material and software resources are used only for their intended purposes. David K. Hsiao Douglas S. Kerr (1987) claims that security generally is comprised of five main goals: authentication, authorization, integrity, confidentiality and non-repudiation.

Authentication is the process of verifying the identity of an entity, either in person or electronically, where credentials are requested and checked to verify or disprove an entity's claimed identity [1]. Linux and MAC X OS both support local and network-based authentication to help ensure that only users with valid authentication credentials can access the computer's data, applications, and network services [2]. Passwords can be required to log in, wake the system from sleep or a screen saver, install applications, or change system settings. In addition, Mac OS X supports emerging authentication methods such as smart cards. By securely caching network-based credentials, Mac OS X allows you to authenticate offline. So users can disconnect their notebook computer from your office network and work offline using the same user name and password.

Authorization is a process of granting access in operating system that protects computer resources by only permitting those resources to be used by resource users that have been granted authority to use them [1]. It is responsible for allowing or denying user different actions such as request to read or write a file, to connect to a website or kill a process. Assuming, for example, that someone has logged in to a computer operating system or application, the system or application may want to identify what resources the user can be given during this session[3]. Thus, authorization is sometimes seen as both the preliminary setting up of permissions by a system administrator and the actual checking of the permission values that have been set up when a user is getting access. Logically, authorization is preceded by authentication.

In conclusion,protection mechamisms are implemented in operating system to support different security policies. These security policies serve the purpose to maintain the system's quality attributes, among themauthentication, authorization, integrity, confidentiality and non-repudiation. In other words, a secued operating system is the plan
that shows where security measures need to be placed. If the plan describes a specific solution then, prior to building such a plan, one would make a risk analysis. The operating system then can be capable to distinguishe between requests which should be allowed to be processed, and others which should not be processed.Thus, the goal of the security system is to authenticate a subject and authorize its access to any object. The risk of unauthorized modification or destruction of data, disclosure of information, and denial of access to data while in transit should be considered along with the risks associated with data that is in storage or being processed. In addition, system engineers should implement security measures to preserve, as needed, the security goals authentication, authorization, integrity, confidentiality and non-repudiation, including application software, while the information is being processed, in transmit, and in storage.
