Study Notes
Introduction to Information Systems
- Information systems encompass a vast network of interconnected devices and technologies.
- Computers transitioned from calculation tools to automation devices for business processes.
- In the 1980s, organizations integrated telecommunications and information systems departments under an IT department.
- Computer networking originated in the 1960s with the development of the internet.
A Brief History of the Internet
- ARPANET's creation response to the launch of Sputnik (1957).
- ARPANET (Advanced Research Projects Agency Network) aimed to provide secure communication between US research institutions.
- ARPANET later evolved to DARPA (Defense Advanced Research Projects Agency).
- In 1968, DARPA sought proposals for networking technology.
- Bolt, Beranek, and Newman (BBN) won the proposal to connect computers nationwide.
- ARPANET went live in September 1969.
- Development of proprietary protocols for early networks made communication difficult.
- TCP/IP protocol invented to allow networks to communicate regardless of protocols.
- TCP/IP became the standard protocol, allowing the term "internet" to describe the interconnected network.
Internet Vocabulary
- Packet: fundamental unit of data transmitted over the internet.
- Hub: network device connecting devices and broadcasting packets to all.
- Bridge: connects two networks, allowing only needed packets to pass.
- Switch: connects multiple devices, filtering packets based on destinations.
- Router: receives and routes packets to their destinations.
- IP Address: unique identifying number for every communicating device on the Internet.
- Domain Name: human-friendly name for a device on the internet followed by a Top-Level Domain (TLD).
- DNS (Domain Name System): internet directory for proper routing.
- Protocol: set of rules allowing devices to exchange information across networks.
Growth of Internet Usage
- Internet usage grew significantly over time from governmental and academic use to broader accessibility.
- Tim Berners-Lee introduced the World Wide Web (WWW) with hypertext in 1990.
- The Mosaic browser (1993) facilitated navigation of the internet.
- The dot-com boom was sparked by NSF's transfer of Internet management to commercial organizations (1991).
Web 2.0
- Early web development required webmaster expertise to set up servers, databases and domains.
- Web 2.0 technologies made content creation and website maintenance easier for everyone.
- Examples include Blogger and Wikipedia.
The Internet vs. World Wide Web
- The internet is an interconnected network of networks. Runs many services like email, voice communication, and file transfers.
- The World Wide Web is a component of the internet, using web servers to deliver HTML pages to web browsers.
The Growth of Broadband
- Early internet access relied on modems over analog phone lines.
- Modems modulated and demodulated signals to connect to dial-up networks.
- Broadband speeds measure in bits per second (bps), increasing drastically over time.
- Broadband connections deliver substantially higher speeds and utilize cable lines, DSL or satellites.
Home Broadband vs Dial-up
- Broadband internet access steadily gained popularity as dial-up access declined from 2000 to 2013.
Importance of Broadband
- Broadband internet usage impacts how people interact and use the internet.
- Broadband technologies revolutionize how we live and interact.
- Access to broadband is recognized as a basic human right by the United Nations.
Wireless Networking
- Wi-Fi converts internet signals to radio waves allowing wireless connections.
- The range of Wi-Fi signals is approximately 65 feet.
- Multiple Wi-Fi specifications have emerged over time.
- Mobile networks integrate data networks into mobile phone systems, providing internet access on smartphones.
- The 3G network release marked a major breakthrough in mobile internet access in 2001.
- Bluetooth is used for short-range connections, not for Internet access.
- VoIP (Voice over IP) converts audio signals into digital format for transmission over the internet. Examples include Skype and Google Hangouts.
Organizational Networking
- Local Area Networks (LANs) are small networks usually within a single building or campus.
- Wide Area Networks (WANs) encompass larger areas with nodes in various locations such as cities or even states.
- Client-server systems use servers for shared information access among users.
- Intranets are private networks within an organization, leveraging existing internet technologies.
- Extranets extend intranet access to authorized external entities like suppliers, vendors, and business partners.
- Cloud computing delivers hosted services over the internet, divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), Software-as-a-Service (SaaS).
