“Compute” is not an unfamiliar word for human beings. In order to compute the hardware and the software of a system need to work in collaboration with each other executing a series of tasks and thus accomplishing the required computing. The present age has dawned to supercomputing owing to the rapid advancements in Information Technology. More >
The File Systems in Multimedia Operating Systems are said to have extended the File System Structure of the Unix Operating System. As characteristically notified above, the file types that are relative to the multimedia operating system require quite a number of adjustments. This basically is because of the massiveness of the files, their need for runtime instructiveness with the server, the continuity of retrieval of data and synchronization.
The handling and organization of these specific file types was a cumbersome task when the original and conventional file systems was arranged to accommodate them. With the increasing trends of graphical and media files embedded e-mail windows the handling of multimedia files has become inevitable. Their performance often comes at stake if their implementation is done using the conventional file system.
MMFS is a Multimedia File System. It extends the UNIX File System (UFS). Specifically designed for multimedia applications that may be interactive in nature, MMFS is characteristically supportive of the real-time and faster environments of the Multimedia file types. It supports single-medium editing and multiple-media playback environments. It does so by getting implemented in a file structure which is two dimensional in nature. More >
Studies by various researches are emerging to prove the effectiveness of social media in distance learning. For example, recent studies have disclosed that the exposure to an instructor via social networking enhances the motivation level of the entire class and thus results in the betterment of the environment of the classroom as a whole. This in turn is obviously reflective with positive changes in the performance of the students.
The most popular and the most massive of the social networks namely MySpace and Facebook have been known to have been the foremost contributors in this regard. This is owing to the reason that even the most ‘technology-unfamiliar’ of the people (mostly those living in remote locations where awareness to computing sciences are not very common) have heard of these ever famous social networks. Thanks to media coverage internet environments are recognized and understood even where they do not exist. More >

“Multimedia support in operating systems is one of the crucial prerequisites for a successful multimedia system”, quotes Steinmetz and Nahrstedt (2004) in their well-researched book Multimedia Systems. Multimedia Operating Systems are characteristically different from the traditional systems that work behind traditional applications. Some noticeable characteristics of multimedia operating systems may be narrated as follows:
• Increased File Sizes, thus Storage Spaces
The file sizes of Multimedia systems may be quite large in size. For example a MPEG file of about a hundred minutes may need approximately a storage space of 1.125GB. Similarly, a High Definition Television or HDTV file may need up to about fifteen GB of storage space. With the said file size proportions imagine a server that has to store several media files of similar and more sizes. Such a server would definitely need terabytes of storage space.
• Faster Data Transfer Rate Required
The media that are continuous in nature such as audio and video files need to execute at a relatively faster data rate than that for normal non- media file types. For example, considering digital video, it is observed that a digital frame of the video is displayed at a conventional resolution of 800×600. If the resolution of 24 bits is used for the representation of each pixel (which permits the formation of roughly 16 million different colors) the amount of data that needs to be stored for a single frame of the video is about 800x600x24 = 11,520,000 bits. Similarly, if the rate at which the frames are displayed is around 30 frames per second, then an around 345 Mbps of bandwidth is needed to run the file.
• Playback Timing Delays
Timing delays during playback are a critical factor when it comes to multimedia applications. Even after a media file has been sent to the client the process of that file’s playback requires continued delivery of the file. If this continuity of interaction is disrupted during playback then the viewer will have to face disruption in the running of the media. (Silberschatz, Galvin, Gagne, 2011).
Data is everything around us. Facts are everything that exists. Data can very finely be defined as a combination of facts and figures. Therefore it can be affirmed that everything that exists is data. Data is bound into two types of restrictions. It can be categorized as either human process-able or machine process able-data.
Human Process-able data is composed of Intelligence, feelings, emotions and intelligible related facts and data. On the other hand, machine process able data is referred to as that type of data that is quant-able and can be comprehended by machines.
Social media marketing is very important for fashion industry. Social media can enhance the awareness of fashion products by comparing the characteristics of one type of fashion product with another’s. It helps prospective clients to establish a preference for their fashion product and to ultimately become loyal customers. Social media, with its millions of users, is a great place for a fashion companies to introduce their products and enhance awareness of their characteristics. This encourages prospective consumers to remember the fashion product enabling them to relate to it at various instances.
Decision Support Systems are one of the types of information systems that assist in medicine. They can be termed as information systems that assist in decision making. Improved decision making can be achieved by information systems that are flexible, interactive and adaptable.
Organizations use Decision Support Systems in order to make High level decisions.
HISTORY OF DSS IN MEDICINE
Computers have assisted man ever since their inception. The middle of the twentieth century was the time when the first research combining computers and medicine was published. Then there was no stopping at all. The last decade of the twentieth century witnessed the formal making of decision support systems in medicine usually referred to as clinical decision support systems.
The decision Support Systems in Medicine may either be knowledge based or may not be knowledge based.
Continuing from where we left in the previous post it is imperative to mention that since school going students are the backbone of an entire generation of individuals they need to be dealt with in extremely careful and nurturing manner.
The technology equipped times of today do not make it easy for elders to control the way technology is utilized by students within the classroom. The role of school counselors is very important for the ethical brought up of students. This role is not restricted to the ethics of class rooms only. The parents of the students must also be counseled for a collaborative effort.
A quick course in classroom ethics may sound like a constructive idea for training students but it would not be sufficient to bring about the intended change. An overnight change is also impossible. The precaution and reform process should be continuous and the following suggestions should be taken under account when conducting it:
The onset of the era of computing technology bought forth a number of challenging issues for man. Accompanying the limitless boundaries of ease and efficiency computing also brings forth certain issues that need mentoring for the digital age to survive. Data boom accompanied two major issues which were in relation to its ever expanding volume and its handling and storage.
Enormous volumes of data are addressed via the inception of huge storage devices but the backup and recovery of data in case of a system crash or storage device failure is not just a piece of cake. The only solution to this is instant backup which in turn originates a new problem slowing down the system due to higher backup frequency. Moreover, the parallel copy being created may not be available to run the system in case of disaster until restored on the original system completely.
BDR (Backup Disaster Recovery) Device emerges as a SAVIOUR and not only secures data with multiple backups but also facilitates instant switching to the backup data for real time processing in case of any disaster or maintenance work. This proposes like working on the original system even if the local storage device crashes. The main features of a BDR device are as follows,
