1. Name and explain components in the architecture of a computer system? The architecture of a computer system consists of following components (a) Central Processing Unit (b) Arithmetic and Logical Unit (c) Main Memory (d) I/O Unit (e) Bus Interconnection (a)CPU CPU stands for “Central Processing Unit”. CPU is the most important component of the computer. It is also known as processor.
Computer components are divided into two major categories namely hardware and software. Hardware is the machine itself and its connected devices such as monitor, keyboard, mouse etc. Software are the set of programs that make use of hardware for performing various functions. Functional Components of Computer The computer plays a vital role in the lives of human worldwide. They made a great influence in every ground like science, medicine, transportation, business, entertainment, communication.
Another important area for the technology is animation, which requires massive amounts of disciplines. Grid provides a series of distributed computing resource through LAN or WAN. To the terminal user of application, as is he is using a super virtual computer. This idea will realize safe and coordinate resource sharing among person, organization and resources, and will create virtual and dynamic organization. Grid computing is a method of distributed computing.
There are many subsystems of Computer Integrated Manufacturing which help in integration of the manufacturing process from ideation to application. Few Computer Aided Techniques are Computer Aided Design (CAD), Computer Aided Process Planning (CAPP), Computer Aided Quality Assurance (CAQ), Enterprise Resource Planning (ERP), Product Lifecycle Management (PLM) and Manufacturing Execution System (MES). The devices which help in implementing an integrated manufacturing system are Computer Numeric Controlled machine (CNC), Direct Numeric Control Machines (DNC), Programmable Logic Controllers (PLC), and Monitoring Equipment. The system should be capable of not only storing data but also to act in real
• Procedures and Work Instructions This subcomponent is depend on the knowledge and experience that organization used to ensure the quality assurance of the given software for example having a detailed guideline ensures that all members of the organization must follow to achieve some goal of the software. Usually the quality assurance procedures that undertaken in the organization offer detailed definitions for the performance of specific types of development activities in a way that assures effective achievement of quality
So, to eliminate this problem, a new system is created and it is called as a computerized system or CBIS. A computer-based information system (CBIS) also is usual of hardware, software, databases, telecommunication, people, and procedures that are constructed to collect, control, store, and process the data into complete information. A CBIS also have five functions, there are input which consist raw data either from organization or outside the organization to be processed. Second is process which transfer raw data into information, third is output which is information that has been processed, storage which is place to store the useful information and lastly is control which to control the evolving of information system. 1.2 What is component of Computer-based information system 1.2.1 A computer-based information system (CBIS) is an information system in which the computer plays a major role.
In its most general form it is concerned with the understanding of information transfer and transformation. Particular interest is placed on making processes efficient and endowing them with some form of intelligence. The discipline ranges from theoretical studies of algorithms to practical problems of implementation in terms of computational hardware and
Assignment 1. 1) Differentiate between database management system and information retrieval system by focusing on their functionalities. There are many functions of database management system and information retrieval system. But, there are differences when focusing on their functionalities. Database management system is a software package that allows data to be effectively stored, retrieved and manipulated, and the data stored in a DBMS package can be accessed by multiple users and by multiple application programs like(Oracle) .For an information retrieval system, according to Harter, it is a device interposed between a potential user of information and information collection itself that given information problem, the purpose of the
Information management is a process of gathering and managing of data/information from one or more sources and the conveyance of that data/information to one or more users. Many broad enterprises have a focal information management purpose to empower this process. Information management is a consistent arrangement of six firmly associated exercises, to be specific: identification of data needed, acquisition and conception of that data, analysis and clarification of information, organization and storage of information, information confirmation and distribution and to wrap things up information utilization. An organization needs to maintain a strong core of information to run the business (Chassell and Smith 2013: 5). Information is essential
Chaptar-1 1. What is a Computer? Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculations. The basic components of a modern digital computer are: Input Device, Output Device, and Central Processor.
