Notes with worthy tutorials
An analog computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. As an analog computer does not use discrete values, but rather continuous values, processes cannot be reliably repeated with exact equivalence.
Q. What are the functions of operating system? Functions of Operating Systems: Operating system’s size, organization and scope of operating vastly depends on the size, organization and use of various computer system. Obviously not all operating systems can be used on all systems. Functions of an operating system are always targeted to meet the needs. … Read more
Software project manager is the person who manages software projects. She or he will be attached to the project from the beginning to the end and continue with the life cycle of the software. It is impossible to write a standard list of responsibilities a software project manager. The job varies with organization and product being developed. However, following are the responsibilities most software project managers have to deal with.
Software project management is an essential part of software engineering. However, good management won’t guarantee success, but bad management results in project failure. Software managers are responsible for planning and scheduling development. They supervise the work to ensure that it is following the standards and monitor progress to check that the development is on time and within budget. Software engineering is different from other types of engineering in a number of way which particularly makes software engineering difficult.
A computer is a multipurpose electronic device that can receive, store, process data and deliver information. A computer takes data such as numbers, text, images etc. as input and then process those data and converts those to useful information. Additionally, a computer can also store data and information both for future use. Also, a computer can perform scheduled tasks. Computers are programmed devices. Computer programmers write programs or software for computer which actually takes input, process it and outputs information.
The measurement of the efficiency of information systems is the evaluation of information systems. The evaluation of information systems depends on the amount of efficiency in workflow and management an organization achieved by implementing an information system. Evaluation of information systems is measured based on a few criteria as follows:
An organization’s management generally includes one or more levels depending on the size of the organization and it’s managing areas. Different types of information systems are required for different purposes of these levels. However, information systems can be categorized as follows,
Information systems are in use from an ancient time. With the development of computing technology, computers became an important part of today’s modern information systems which satisfies speed, dependability etc.
Systems that collect, verify, store, process, report and update data to output valuable and useful information are called information systems. Information systems are being used from ancient time period. With the development of computing technologies and it’s uses, modern information systems are computer based information systems which can process billions of data to output desired information in seconds or minutes. Various types of computer based information systems are available.
