The new syllabus of DOE’s various levels of courses, popularly called O-level, A-level, B-level and C-level is out. This syllabus has been designed keeping in mind the various developments taking place around the world in the field of computers. While keeping in mind the level of students studying the various levels, the degree of difficulties of the syllabus have been very well designed. I hope that after the new syllabus the courses would be as popular as they were before. There had been a long struggle between Training Institutes and Government Organizations, since these organizations would not recognize the degree/diploma given by them. Students passing out from these institutions were not given jobs based upon the said diplomas/degrees. Ultimately, the Government formed a society under the Department of Electronics, called DOEACC, which conducts tests and gives grades to the students irrespective of the institutes where they have studied. It is also possible to give the test without having any proper institutional studies. This is more or less on the terms of SAT and GRE conducted by USA. The only difference is that this is not online. There are fixed dates for the exams. The course for this has been designed for students to appear in the exams at various levels. These levels are O-level, A-level, B-level, C-level. The most popular among these is the O-level, since it is the entry level. Once you have cleared the O-level, you are eligible for a government job. Each course has been divided into various modules. Various books are available for various modules. This book is also made for you to prepare for the O-level course. This book has been written totally in accordance with the syllabus. Each chapter has been embedded with the screen shots for you to know what to expect on the screen, while running the application. Each chapter contains examples which can be attempted to supplement the reading. At the end of the chapter, there is a thorough revision of the text read. Not to mention of the questions provided in the beginning, both in the form of objective and subjective. The book also contains Sample papers which are based on the samples provided by DOEACC society. These would help you in preparing for the exams.

    Introduction to GUI based Operating Systems Price 2.99  |  2.99 Rewards Points

    An operating system (OS) is a set of computer programs that manages the hardware and software resources of a computer. It processes raw data which is gi ven to the computer as input. It then allocates and manages the tasks of the internal system resources of the computer. It is the operating system which performs basic tasks such as controlling and allocating memory, prioritizing system requests, controlling input and output devices, facilitating networking and managing file systems. Most operating systems come with an application that provides an interface to the operating system managed resources. These applications have had command line interpreters as a basic user interface, but more recently have been implemented as a Graphical User Interface (GUI) for ease of operation.

    Windows is nothing but graphics-based operating environment from Microsoft. It provides a desktop environment similar to the Macintosh, in which each active application is displayed in a resizable, moveable window on the screen. Initially Windows ran on DOS platform, but now-a-days it runs on its own platform. Windows 1.x, Windows 286 (2.x) and Windows 386 were first attempts. Windows 3.0 had its own enhanced user interface and ability to manage extended memory, upto 16MB with built-in DOS extender. Windows 3.1 (1992) was faster and supported multimedia, true type fonts, drag and drop, among other features. It was the last of the Windows versions based to work on DOS platform. From this point onward Microsoft introduced Windows 95 which was independent of DOS and had its booting capabilities. Windows for Workgroups for was introduced in 1993. It was the first version of Windows which truly supported networking. This was later enhanced to Windows NT, which was introduced in 1993.

    Elements of Word Processing Price 2.99  |  2.99 Rewards Points

    Word processor is a computer program for processing of words, very similar to a food processor ( mixie ) which processes food. Most of the word processors would start from a blank screen assumed to be a blank page with a blinking starting point known as Cursor . For all practical purposes it is like a typewriter, but it is much more than that. You can type the text (even enter graphics) in the word processor, save it under a name to recall it again and again. Spell check it for errors, format it to look good, and then if needed print it too. This makes it much easier for writing the text since you can make as many mistakes as you like since you can correct them by just pressing a key. This way you save a lot of paper and make the document look more neat and clean.

    Computer Communication and Internet Price 2.99  |  2.99 Rewards Points

    It is not that the Personal Computers are for personal use only. They can be used for sharing of information too with others having similar type of equipments. Logically it sometimes is more feasible to have a number of PCs than having a bigger computer which can give the same throughput as the number of PCs. But, overall it becomes a expensive proposition and sometimes is not feasible, specially for individuals and small businesses or small companies. Another problem arises for those who are physically placed at a distance. They would need to send messages and receive messages, or use the same data at, or share program at, many different locations. One answer to this problem is to keep separate data files at each location, but this approach is very costly and potentially a dangerous solution. It is very expensive to maintain these redundant files of data and difficult to ensure the continuing accuracy of data at any one location. The solution of both, the need for more power and the ability to receive, send messages and share data, are found in data communication technology.
