Answer:

They are the cardinality ratio and participation constraints.

Explanation:

The Cardinality Ratio: This is for the binary relationship that specifies the max number of instances of relationships in which an entry can take part in. As an example, the Student Of binary relationship form, School: Student, the cardinality ratio of this is 1: N. and that means each of the schools can be mapped to any number of students, however, one student can be mapped to only one school. And various possible cardinality ratios for various types of binary relationships can be 1: N, N:1, 1:1, and M: N.

Participation constraint: This stipulates that an entity being be contingent upon another entity through relationship form. And it stipulates the least figure of instances of relationship which each of the entity can indulge in, and is often termed as least cardinality constraint. And we have participation types: partial and total.

What are the six peripherals of a computer system
Lubov Fominskaja [6]
Peripherals fall into three categories:
1. input devices are devices that put commands inside computers such as keyboards, mouses, and joysticks but the first two are the mostly used nowadays
2. output devices are what computers give out such as monitors, printers, speakers and I think projectors also fall into that category
3.storage devices such as a optical drive, hard drive, SDD, flash drive
So the main ones might be a mouse, keyboard, monitors, I think printers, hard drives and flash drives but speakers might be considered as one instead of a flash drive.

Explain Organizational approach to System Analysis and Design
9966 [12]

Answer:

The major goal of systems analysis and design is to improve organizational systems. Often this process involves developing or acquiring application software and training employees to use it. Application software, also called a system, is designed to support a specific organizational function or process, such as inventory management, payroll, or market analysis. The goal of application software is to turn data into information. For example, software developed for the inventory department at a bookstore may keep track of the number of books in stock of the latest best seller. Software for the payroll department may keep track of the changing pay rates of employees. A variety of off-the-shelf application software can be purchased, including WordPerfect, Excel, and PowerPoint. However, off-the-shelf software may not fit the needs of a particular organization, and so the organization must develop its own product.

Explanation:

Information systems analysis and design is a method used by companies ranging from IBM to PepsiCo to Sony to create and maintain information systems that perform basic business functions such as keeping track of customer names and addresses, processing orders, and paying employees. The main goal of systems analysis and design is to improve organizational systems, typically through applying software that can help employees accomplish key business tasks more easily and efficiently. As a systems analyst, you will be at the center of developing this software. The analysis and design of information systems are based on:

Your understanding of the organization’s objectives, structure, and processes

Your knowledge of how to exploit information technology for advantage
