• Software – Software is the assemblage of operating system, different applications, programs need to make things working – basic command execution, commands used for signal interruption, commands used to activate and deactivate the hardware components attached to the system. Different types of programs consisting of the procedure to adopt makes the system work.
o Application software – The software is basically designed to serve specific purpose.
o System software – The software is designed to manage the working of the computer. Operating system is a type of system software used to manage the resources and provide service to the requested device. Device driver another type of system software is used to control the devices and make them function.
o Malicious software- This kind of software is designed to harm the host system. It is usually used to lock the system intentionally, waste memory, and create obstruction in regular doings according to Information science assignment help experts
o Central processing unit (CPU) which is responsible to take any logical decision or provides results of a mathematical operation.
o Random Access Memory (RAM) is a set of memory locations used to store code and data.
o Read-Only Memory (ROM) is set of memory locations which contain set of programs hard-cored at the time of manufacture. The contents cannot be erased.
o Video cards helps in bringing out graphical features.
Input devices are used to insert data into the system for processing. Some of these devices commonly used are mouse, touchpad, keyboard, joystick, image scanners. Output devices are the part of the system which displays the output of the processing. Printers, speakers, monitors are some of the output devices. Storage devices like pen drive, discs are used as secondary memory devices.
• People – The users of system can vary, irrespective of location and caste. To make the computer work and fulfill the necessity of the users – use an application that can cater their purpose, opt to program using a programming language or any web-based facility to serve their purpose.
• Procedures – The procedures vary from one to another depending on what is being dealt. The process to be implemented is divided into minuscule. Using the appropriate language, tools the designed entity is brought into reality. System programming language is used to design any operating system, the concepts and functions used make them different from each other. Object oriented language is used to make the input/output devices work. Web-based applications use a mix of languages – HTML, java script and many in line.
• Networks – Many systems are connected using different kinds of wires- Optic cables, shielded/ unshielded twisted pair, coaxial cables to transfer data from one end to another end of the network. Networks vary in size –LAN, WAN, MAN, WLAN, SAN, PAN, EPN, VPN and topology- point-to-point, star, bus, ring, mesh and many in line.
The components of information system have enabled transmission of data from one corner of the world to another. Each component has its role to play and the aggregation of the work has brought information system into reality. The components vary with their functionalities they display. Software varies in number and functionality – application software, system software and malicious software. Hardware come in different sizes and vary with the task they perform – used to store data, used to accept input/display output. Procedures vary with the role they need to play. Networks vary with size and topology as said by an assignment expert.
