Internet and Networking Technology Fundamentals

A hub is a physical networking device used to connect multiple devices in a network, making it hardware.

Network, Transport, and Physical are all layers of the OSI model, whereas System is not a standard layer in that model.

Switch, Hub, and Bridge are all networking hardware devices, while Satyam is a company name.

Java, ActiveX, and Macromedia Flash are technologies used for client-side or web-based interactivity, whereas Oracle is primarily a database management system.

Bandwidth is a measure of data transfer rate, typically expressed in bits per second (bps). It represents the capacity of a communication link to transmit data.

Yahoo, Rediff, and Hotmail are web portals or email service providers. SMTP (Simple Mail Transfer Protocol) is a communication protocol used for sending emails, making it the odd one out.

RFC stands for Request for Comments. These are documents published by the Internet Engineering Task Force (IETF) that define standards and protocols for the internet.

The Open Systems Interconnection (OSI) model is a conceptual framework that characterizes the communication functions of a telecommunication or computing system into 7 distinct layers.

E-mail is short for Electronic mail. It is a method of exchanging messages between people using electronic devices.

An IPv4 address is a 32-bit numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.

In IPv4, the address is represented in dot-decimal notation, where four decimal numbers are separated by dots (e.g., 192.168.1.1).

The .edu top-level domain is a sponsored top-level domain in the Domain Name System of the internet, restricted to post-secondary educational institutions.

Internet Explorer is a graphical web browser developed by Microsoft for the Windows operating system.

SMTP (Simple Mail Transfer Protocol) is a communication protocol used for the transmission of email messages across IP networks.

IP stands for Internet Protocol. It is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries.

A network switch is a networking hardware device that connects devices on a computer network by using packet switching to receive and forward data to the destination device.

JAVA, HTML, and Servlets are technologies or languages used for web development. Internet Explorer is a web browser, making it the odd one out.

UUCP (Unix to Unix Copy) is a suite of computer programs and protocols used for communication between computer systems, originally developed for the Unix operating system.

The Internet Protocol (IP) is the primary network layer protocol in the Internet protocol suite, commonly referred to as TCP/IP.

FTP (File Transfer Protocol) is a standard network protocol used for the transfer of computer files between a client and server on a computer network.

DNS stands for Domain Name System. It is a hierarchical and decentralized naming system for computers, services, or other resources connected to the internet.

A network bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments.

Physical connection in a network refers to the actual transmission medium, such as copper wires, fiber optic cables, or coaxial cables, used to connect devices.

An email address consists of a local part (username), followed by an @ symbol, and then a domain name.

Windows NT 4.0 is a preemptive, graphical 32-bit operating system that was designed to be the business-oriented operating system in the Windows NT line.
