What is the introduction of Cloud of Things (CoT)?
Cloud of Things (CoT) is an integration of Internet of Things (IoT) with Cloud Computing. It is a high-performance cloud-based IoT application platform that enables remote monitoring, management, and control of IoT-enabled devices across distributed networks. The CoT represents the ongoing trend for next-generation applications of IoT smart services, where massive amounts of data generated by IoT devices are processed and analyzed in the cloud to produce actionable insights for various smart applications. Architecture of Cloud of Things IoT objects generate large volumes of data that must be processed and analyzed in the cloud to produce sensitive ...
Read MoreHow to Hack an Open WiFi?
The process of gaining unauthorized access to any data or system is commonly known as hacking. In networking contexts, this often involves identifying vulnerabilities in wireless networks and their security protocols. Types of Hacking Understanding the different types of hacking helps distinguish between legitimate security testing and malicious activities: White hat (Ethical Hacking) − Authorized security professionals who perform penetration testing to identify system vulnerabilities. Companies hire them legally to find and fix security weaknesses. Black hat (Malicious Hacking) − Unauthorized individuals who exploit system vulnerabilities for personal gain, data theft, or financial ...
Read MoreWhat are the differences between IIOT and IOT?
Let us understand the concepts of Internet of Things (IOT) and Industrial Internet of Things (IIOT) before learning the differences between them. Internet of Things (IOT) It is described as the physical devices like mobiles, PCs, home appliances and many more electronic devices that are embedded with sensors, software and other technologies to transmit data and communicate among devices through the Internet. Examples: Air conditioners, sensors, smart watches, mobile phones, smart home systems, fitness trackers. Industrial Internet of Things (IIOT) It is described as using the internet of things in industrial applications and sectors. The ...
Read MoreWhat are the differences between DTE and DCE?
Let us understand the concepts of Data Terminal Equipment (DTE) and Data Communications Equipment (DCE) before learning the differences between them. Data Terminal Equipment (DTE) At the physical layer, the function of DTE is to look for clocking from the device on the other end of the cable on a link and look for a frame-switching service. The device receives clocking from the DCE and uses it to synchronize data transmission. The customer devices or the DTE pass data from a host computer on a customer network for transmission over the Wide Area Network (WAN). DTE devices ...
Read MoreWhat are the differences between Client OS and Server OS?
Let us understand the concepts of Client Operating System (OS) and Server OS before learning the differences between them. Client Operating System (OS) A client operating system is designed to work on end-user devices such as desktops, laptops, tablets, and smartphones. These operating systems are optimized for individual users and provide direct interaction capabilities through graphical user interfaces. Manages hardware components including printers, monitors, cameras, and input devices Supports single-user operations with personal computing tasks Capable of requesting and consuming services from server operating systems Provides cost-effective multiprocessing power ...
Read MoreWhat is a Botnet?
A botnet is a collection of internet-connected devices that have been infected with malware and are controlled remotely by cybercriminals. These compromised devices, called "bots" or "zombies, " operate without the knowledge of their owners and can be used to carry out various malicious activities. Botnets typically infect devices that have vulnerabilities such as outdated firewalls, unpatched operating systems, or insufficient antivirus protection. Once infected, these devices become part of a larger network that can be commanded to perform coordinated attacks. Botnet Architecture ...
Read MoreWhat are the differences between HDMI and VGA?
Let us explore the key differences between Video Graphics Array (VGA) and High Definition Multimedia Interface (HDMI), two important display connection standards used in computers and multimedia devices. Video Graphics Array (VGA) VGA stands for Video Graphics Array and was first developed by IBM in 1987. It remains widely used for connecting video cards, computer monitors, TVs, and laptops, particularly in older systems and budget applications. VGA uses analog video signals with five components (RGBHV): Red − Analog red color signal Green − Analog green color signal Blue − Analog blue color signal Horizontal sync ...
Read MoreWhat is Internet Relay Chat (IRC)?
Internet Relay Chat (IRC) is a protocol used for real-time interactive text messaging and simultaneous conferencing. It is primarily designed for group communication in discussion forums called channels, but also supports one-to-one private messaging and file transfers. IRC enables people from around the world to communicate in real time through distributed networks of IRC servers. Users connect to these servers using IRC client software to join channels and participate in conversations. IRC Network Structure IRC Server User 1 User ...
Read MoreWhat are the types of Transmission Technology?
Transmission technologies in computer networks are divided into two fundamental types based on how data is delivered between hosts: Broadcast Networks − One-to-many communication where data is sent from one source to multiple destinations simultaneously Point-to-Point Networks − One-to-one communication where data is sent directly between two specific hosts Broadcast Networks In broadcast transmission, data is sent from one source host to all other hosts present in the same or different networks. This is a one-to-all transmission method where a single message reaches multiple destinations simultaneously. ...
Read MoreWhat are the types of Virtual LAN (VLAN)?
A Virtual LAN (VLAN) is a logical subnetwork that groups devices together regardless of their physical location on separate local area networks. Unlike traditional LANs that are limited by physical connections, VLANs provide flexibility through software-defined network segmentation. VLANs enhance network security and management by controlling which devices can communicate with each other. They operate based on logical connections rather than physical proximity, making network administration more efficient and scalable. How VLAN Works When a switch receives an Ethernet frame, it either processes an existing VLAN tag or inserts one into the Ethernet header. Frames from other ...
