Machines understand only binary language i.e. Software comprises the entire set of programs, procedures, and routines associated with the operation of a computer system. A software component infrastructure is a set of interacting software components designed to ensure that a software system or sub­ system constructed using those components and interfaces will sat­ isfy clearly defined performance specifications. Embedded Systems Hardware Components. System software has two major components: (1) the operating system and (2) system utilities that provide various maintenance functions. The objective of an information system is to provide appropriate information to the user, to gather the data, processing of the data … The goal of component based software development is to allow developers to construct a software system by integrating existing software components in a plug-and-play manner [1] like assembling mechanical hardware or furniture in daily life. As discussed before, the first three components of information systems – hardware, software, and data – all fall under the category of technology. The hardware components of a computer system are the electronic and mechanical parts. Computer hardware can interact with the higher level computer programs with the help of device drivers. The power supply is an essential part of any embedded systems circuits. Application Software: Software that enables the user to meet their requirements i.e. An operating system is a large and complex system that can only be created by partitioning into small pieces. As we know embedded systems are the combination of hardware and software. These device drivers act as a translator between the application of the user and the hardware device. Operating system shares the various OS system components like File, Process Memory, I/O device management, etc. Software required to run the hardware parts of the computer and other application software are called system software. Software, instructions that tell a computer what to do. An Information system is a combination of hardware and software and telecommunication networks that people build to collect, create and distribute useful data, typically in an organisational, It defines the flow of information within the system. Computer hardware refers to the physical parts or components of a computer such as monitor, keyboard, Computer data storage, hard drive disk, mouse, system unit (graphic cards, sound TYPES AND COMPONENTS OF COMPUTER SYSTEMS Hardware and Software Computer hardware is the collection of physical elements that constitute a computer system. Components of system software. There are different hardware components like power supply, processor, memory, timers and counters that make the embedded hardware. System software consist of the following elements: • Device Driver: it is a computer program. The software components of a computer system are the data and the computer programs. The term was coined to differentiate these instructions from hardware—i.e., the physical components of a computer system. Systems software carries out middleman tasks to ensure communication between other software and hardware to allow harmonious coexistence with the user. Power Supply. (This was back when anything to do with computers had to be beige. A file is a collection of related information which is should define by its creator. An interface is needed because hardware devices or machines and humans speak in different languages. Click Here to see the desktop system these notes were originally prepared on. The first thing is to prepare software modules ready for component based software development. Each of these will get its own chapter and a much lengthier discussion, but we will take a moment here to introduce them so we can get a full understanding of what an information system is.
