What is IPv4? Internet Protocol Version 4, commonly known as IPv4 is the fourth revision of the Internet Protocol and an important component of data communication across various networks. Networks use IPv4, a connectionless protocol, extensively in environments like Ethernet that rely on packet-switching technologies. How Does IPv4 Work? IPv4 operates by assigning a unique […]

What is Data Link Layer? The data link layer is a crucial part of how computers send and receive data. It handles turning data into a format that can be sent over a network and ensures it arrives correctly. The layer comes in between physical layer and network layer, and breaks down into two main

Definition A layer in object-oriented design refers to a group of classes that depend on the same modules as other modules. This means that as long as the circumstances don’t change, the components of a layer can be reused. Essentially, the way these classes depend on each other helps to define the boundaries or distinctions

What is Internet Protocol Address? An Internet Protocol address (IP address) serves as a unique numeric identifier assigned to each device like computers, printers, switches and routers on a TCP/IP network. The IP address forms the backbone of any networking architecture. Without it, a network cannot exist. It functions like a street address in a

What Does Network Layer Mean? The network layer is a crucial part of how computers send data over the internet. It’s the third layer in the OSI Model, which is a framework used to understand how networks operate. Think of the network layer as a system that manages how data is sent from one device

Meaning The application layer is the topmost layer in the seven-layer OSI model, which is a way to understand how networks operate. It deals with the software applications that need to connect and communicate over the network. This layer makes it possible for different programs to link up and share information across the internet, focusing

What Does Session Layer Mean? The session layer is the fifth layer in the OSI model which is a framework that helps different computer systems to communicate. This layer manages the connections or “sessions” between computers. It’s responsible for starting, overseeing and closing these sessions between applications on different computers. Understanding the Session Layer The

What Does Internet Privacy Mean? Internet privacy refers to how your personal information is protected while you’re online. It involves a bunch of stuff like rules websites have to follow about your privacy controls you have over sharing your data and efforts to make data use more transparent. When you’re surfing the web you want

Definition Transmission Control Protocol abbreviated as TCP, functions as a communication protocol within network systems. It primarily focuses on sending data packets across the Internet. Operating at the transport layer of the OSI model, TCP facilitates the connection between distant computers. It ensures the reliable transmission and receipt of messages across various supporting networks, including

Meaning An intranet is like a private internet just for a company or organization. It uses the same kind of technology as the internet (Internet Protocol or IP) but is only accessible to people within that organization. Unlike the internet which everyone can use, an intranet is a closed network where only members of the

Data privacy also known as information privacy, involves the careful handling of sensitive information including personal details, financial data and intellectual property. It’s about ensuring that this data meets legal standards and remains confidential and unchanged. There are three main types of data protection: Traditional data protection like making backup copies for recovery. Data security

The transport layer is commonly referred to as Layer 4 within the Open Systems Interconnection (OSI) network model. This model simplifies the process of transferring data between networked computers by dividing the responsibilities into seven distinct layers. Functions of the Transport Layer At the transport layer, several critical functions are performed to ensure data moves

What Does Fax Over Internet Protocol Mean? Fax over Internet Protocol, or FoIP, is a method of sending faxes that utilizes digital packets over the internet. This technology allows the transmission of fax documents in a way that adapts to modern digital environments. Types of FoIP There are two main approaches to using Fax over

Definition A virtual IP address, or VIPA, refers to an IP address that multiple domain names or servers use simultaneously. This setup occurs on a single network interface card (NIC). How are VIPAs Assigned? Network administrators assign a single network IP address to the host server. On this server, various applications such as virtual private

What is Internet Protocol? Internet Protocol commonly known as IP is a crucial communication protocol for sending messages between computers on the same network or across interconnected networks. It forms part of the Internet Protocol Suite, also known as TCP/IP, which consists of various digital message formats and rules. Data Exchange Using IP Computers exchange

What Does “Primary Key” Mean? A primary key serves as a special column or a combination of columns in a relational database table, designed to uniquely identify each record in the table. This identifier helps to swiftly navigate and manage data within the table. Importantly, a table is restricted to having only one primary key.
