TECHNOLOGY

Information systems have five major components:

HARDWARE, SOFTWARE, DATA, PEOPLE, PROCESSES

The first three (3) components of information systems

HARDWARE, SOFTWARE, DATA

the physical component of an information system – tangible parts to users. Computer, keyboard, system unit, and mouse are all examples of information systems _________.

HARDWARE

includes a set of commands that instruct the hardware what to do. This is intangible compared to hardware. Programmers design software this by coding a series of commands instructing the hardware what to do.

SOFTWARE

Two main categories of software are:

OPERATING SYSTEMS AND APPLICATION SOFTWARE

It is a collection of indisputable raw facts. Home addresses, phone numbers, and social networking accounts are examples of pieces of this.

DATA

Information systems can exist without the capability to communicate. Although in today’s interconnected world, it is rare for a computer not to connect to another device or to a network. The People and Process components of information systems fall under this category.

NETWORKING COMMUNICATION

Categories of Networking Communication:

PEOPLE AND PROCESS

It is easy to focus on the technology components alone, but focusing on the people involved in information systems is essential. From the front-line user support staff to systems analysts to developers, the people engaged in information systems are an indispensable element.

PEOPLE

It is a series of steps taken to accomplish the desired goal. Information systems are becoming more integrated with organizational processes that bring greater productivity and better control. Nonetheless, simply automating activities using technology is not enough; companies wishing to gain an advantage over their competitors should focus highly on this aspect of their information systems.

PROCESS

In 1959, he said that information and information systems would become increasingly important, which led him to coin the term “knowledge worker.”

PETER DRUCKER

are the professionals who make and modify knowledge as a fundamental part of their jobs.

KNOWLEDGE WORKERS

Drucker also predicted that a knowledge society would emerge with the growth of knowledge workers and their rise in importance. Others have referred to this phenomenon as the?

KNOWLEDGE ECONOMY, NEW ECONOMY, DIGITAL SOCIETY, NETWORK ERA, INTERNET ERA, AND NOWADAYS, DIGITAL WORLD

During the early years, information systems were centralized and concerned solely with governance and the needs of management. Most information systems and their reports were under the control of accounting departments.

Technology at the time included third-generation mainframe computers such as the IBM 360 and minicomputers. Languages used include Assembler, Fortran, COBOL, and Database. Ethernet networks were developed during this time.

First Era (The mid-1960s to Mid-1970s): Mainframe and Minicomputer

While information systems were still concerned with governance and the needs of management, more departments were beginning to benefit from the technology.

In many companies, steering committees and user-led initiatives determine the scope of additional information systems projects. Technology included the first personal computers (PCs) and midrange computers.

Second Era (The mid-1970s to Mid-1980s): Personal Computer

In this era, concentrated information systems started to spread, and information became deconcentrated. Technological difficulties and costs decreased, and an enterprise's need to share information grew.

During this era, a new position arose in many companies to oversee the procurement and management of multiple information systems: the Chief Information Officer or CIO. Technology during this era included internetworking and the emergence of the Internet.

Third Era (The mid-1980s to Late 1990s): Client/Server

During this era, information systems are still tied to governance and management, although the systems are widely distributed to every employee who needs them across multiple platforms.

This era combined all aspects of the business enterprise, offering rich information access surrounding the complete management structure. Technology now includes social media, search engines, and various computing through a variety of platforms, including laptops and smartphones.

Fourth Era (the Late 1990s to today): Enterprise

This era uses networking technology that delivers applications and data storage independent of the configuration or location of the hardware. Along with high-speed smartphones and Wi-Fi networks, this era has led to new levels of flexibility, such as cloud computing, in which managers may access information systems anywhere with a laptop, tablet, or smartphone.

Rising global competitiveness has forced companies to find better and more cost-effective ways. The solution for companies continues to be to use information systems to accomplish tasks better, faster, and cheaper.

Fifth Era (Moving Forward): Cloud Computing
