Computer hardware Hardware is the computer system physical components which can be classified as input devices, internal along with external memory, a central processing unit (CPU) and output devices. The Input devices capture data into the computer. The CPU processes by doing instructions that the software receives. 1.1 Internal memory The internal memory is a provisional data storage as well as instructions means while external memory stores data and programs exterior to the computer. The output devices decode the processing results into a form that is human-readable. 2. Computer software Software is a series of thorough instructions that manage the function of a computer system. It exists for programs that are developed by programmers. There are two main classes of software: systems software along with applications software. Systems software controls and manages the function of the computer system when it carries out tasks on behalf of the system user (Chitra & Rani 2014). Systems software comprises of three essential classes: software development programs, operating systems, and utility programs. 3. Database A database is an assortment of interrelated files. They can exist on paper, for instance, a telephone directory. Paper databases are inefficient as well as costly to keep. A computer-based database has the benefit of powerful explore services that can be used to find and get information several times faster than the physical techniques (Greenwell, Liu, & Chalmers 2014). Electronic databases provide amenities for system users to add modify or delete records as desired. Indexing characteristics imply that the same essential information is stored in a number of diverse categories. It offers great flexibility as well as allows system users to track, retrieve and put in order information as desired. 4. Business Information Systems A business information system is a group of interconnected constituents that work together to perform input, processing, output, and storage as well as management actions so as to change data into information products. These products can then be used to support planning, forecasting, control, decision making, coordination and functional activities in business. In terms of the elements that do this activity, they can be grouped into five fundamental assets of hardware, people, software, communications as well as data. People resources comprise of the users along with developers of information computer system. It also includes those who assist to maintain along with operating the system like as IS managers in addition to technical support personnel (Chitra & Rani 2014). Hardware resources are computers and other things like printers. Software resources stand for computer programs also called software and connected instruction manuals. Communications resources are networks as well as the hardware along with software required to back them. Data resources encompass the data that a business has access to like computer databases, as well as paper files. In many companies, Business Information Systems (BIS) utilize widespread information technology, like personal computers. The reasons for computerized BIS becoming common are apparent in their benefits like accuracy, speed, and reliability. They as well have a high level of flexibility because of their capability to be programmed to perform a wide range of jobs. There are, on the other hand, some drawbacks to BIS like their lack of ingenuity that humans have. Another drawback is the complexity of adding in other factors into their process of decision making like innovation along with intuition. Information systems are divided into two classes of systems that back a business’s daily business activities as well as systems that back executive decision making. Operations Information Systems (OIS) are commonly concerned with control of the process, transaction processing as well as communications. Management Information Systems (MIS) deals with providing backup to executive decision making (Greenwell, Liu, & Chalmers 2014). Of late this sector of BIS into operational as well as management systems, is helpful for managers evaluating the kinds of BIS currently in use. However, it does not at the moment accurately echo the realism of systems employed in the association. An instance is with the augmented use of electronic data interchange (EDI) as well as inter-organizational e-commerce. For instance, e-business computer systems in addition to enterprise resource planning, systems have features of both operational as well as management systems to give businesses more incorporated information systems. 5. The World Wide Web A network is an arrangement of devices linked to each other via communication connections to give the conduits for information to flow incessantly among people. It lets people work together and also permits hardware like printers as well as faxes to be shared in a more cost-effectively way (Greenwell, Liu, & Chalmers 2014). Networks are significant to the business since they assist a company connects with clients, suppliers as well as collaborators. By doing this, a corporation can place an order for new raw materials more quickly and inexpensively from its suppliers as well as be in touch with the desires of its clients. The Internet lets communication amid linked computers worldwide. Information is conveyed from personal computers whose users require services from computers that have information. These computers host production applications send the services in reaction to requests (Chitra & Rani 2014). The personal computers in homes, as well as businesses, are linked to the Internet through local Internet service providers (ISPs). The ISPs in turn are connected to bigger ISPs with a link to the main national as well as worldwide infrastructure. The Internet can be portrayed as an extensive network system that is made up of minor systems. 6. The World Wide Web and business The World Wide Web can be used by businesses to store data and information through cloud computing. It is the use of web-based computing applications, systems and services that are independently accessed from the original infrastructure. It is allows computing services to be obtainable where as well as when wanted (Chitra & Rani 2014). A business that is web-enabled can be categorized by those parties concerned in business dealings. The most widespread dealings recognized as those when a business is utilizing the Internet to conduct with customers, called business-to-consumer (B2C). Another common type is when a business is doing with other firms, called business-to-business (B2B). The association between a corporation and its customers and suppliers can be radically changed by the openings given by the Internet (Greenwell, Liu, & Chalmers 2014). It happens since the Internet provides a means of avoiding some of the conduit partners. A process of this type is called disintermediation or ‘eliminating the middleman’. Business information systems used in transacting business on the world wide web should be legal and ethical. It can be done by ensuring the system is secure. Controls on systems depend on the two fundamental values of the requirement to guarantee the accuracy of the business data and the provision to guard against damage or loss. Many common threats the business faces in the information systems are accidents, sabotage, natural disasters, vandalism, unauthorized use, theft, and computer viruses (Chitra & Rani 2014).
