What is Network Technology? – Explained

Hello Guys in this blog post we are going to see about the what is network technology ? Come let’s get started.

Network Technology:

The internet was originally created as a way for scientists to share information and collaborate on research projects. However, now it serves millions of people around the world who use it for everything from shopping to banking. At its core, it’s still a network, with all those connections flowing back and forth. That means that if someone tries to access information on your computer, it has to go somewhere. And that somewhere is called the internet. To connect to the internet, you need a router. Routers route data across networks, which helps computers send data to each other and allows them to find other devices online. But routers aren’t just about connecting people to the internet. Routers can do lots of cool stuff beyond just sending messages around. They can help protect your home network from hackers, keep track of traffic flow, manage security settings, and troubleshoot problems.

1. Cisco Networking Technologies (CNT)

The Cisco Networking Technologies Series provides a broad overview of networking technologies, including how they work together to create reliable networks. You’ll learn about the features of network infrastructure devices, including switches and routers, as well as software-defined networking (SDN).

2. Internet Protocol Suite (TCP/IP)

Learn about the components of the TCP/IIP suite, including protocol layering, the data link layer, the network layer, the transport layer, and application layer protocols. You’ll find information on the differences between IPv4 and IPv6, IP addressing, and subnetting. You’ll then explore how these layers interact with each other to enable communication between hosts across different networks and applications, including email, web browsing, and file transfer.

3. Transmission Control Protocol (TCP)

Learn about the basics of TCP, including its data stream structure and congestion control mechanisms. You’ll discover how TCP works in combination with the IP layer of the OSI model, including the basic concepts of ports and socket programming. Finally, you’ll understand the role of TCP in connection-oriented communications, including TCP sequencing, flow control, and retransmission.

4. Transport Layer Security (TLS)

Get an understanding of TLS, including its history, roles, and implementation. You’ll learn about the cryptographic algorithms used to provide confidentiality, authentication, and integrity. Then you’ll take a look at the various types and modes of encryption available in TLS, including symmetric cryptography, public key cryptography, hash cryptography, and digital signatures.

5. Domain Name System (DNS)

Discover how DNS works and how it enables computers to identify themselves over the internet, connecting them to servers where they can exchange e-mail, browse the web, search for content, and manage their personal information. Find out how clients and servers communicate using the UDP and TCP transport layer protocols. Finally, you’ll learn about the DNS hierarchy and the root server.

Advanced Topics

In this section of the course, you’ll gain advanced knowledge of networking topics, including multicast routing, VPN services, and quality of service (QoS) techniques. You will also learn about virtual private networks (VPNs), including OpenVPN configuration, SSL certificates, and IPSec.

1. WiFi Networks

WiFi is a network technology that allows users to connect their personal computers and mobile devices to wireless local area networks (WLAN) using radio frequency signals. These signals allow computers and mobile phones to establish communication over short distances. WiFi technology provides internet access at home, in schools, hotels, airports, restaurants, coffee shops, etc.

2. Bluetooth Technology

Bluetooth is a standard specification for wireless personal area networks (PANs), developed by a consortium consisting of electronics companies Ericsson, IBM, Intel, Microsoft, Panasonic, Toshiba, and Nokia. Wireless PAN (WPAN) technologies communicate between two electronic devices via RF signals rather than wires. Bluetooth was designed to replace cables and make connections simple and quick.

3. IP Address

An Internet Protocol address (IP address) is an identifier assigned to each device connected to a computer network. An IP address identifies the machine on a network and distinguishes it from others on the same subnet. Each IP address consists of four numbers separated by dots. The first three digits identify the manufacturer and model number of the device, while the last digit indicates whether or not the device belongs to a particular network segment. Every computer, printer, router, or web server has an IP address. A computer’s IP address may change if the system reboots or it loses power, and a new IP address is automatically assigned to it by the DHCP server. IP addresses have been traditionally assigned in blocks of 32 bits, with possible values ranging from 0 to 232-1, or 4 billion, although more recently some countries have used variable-length addressing schemes.

4. Routing table

A routing table is a database maintained by a host computer on a network that contains information about routes taken by packets sent out on the network. Routers exchange routing tables with each other to maintain a consistent view of the network topology. When a packet enters the network, a router uses its routing table to determine how the packet should be forwarded towards its destination.

5. Network Topology

A network topology describes the structure of a network. In networking, the term refers to the interconnection among nodes in a network. A network topology can either be flat, hierarchical, starred, or mesh-based. Flat topologies consist of only one tier of nodes. Hierarchical topologies are made of several tiers or levels of hierarchy within the network. Star topologies consist of a central node connected to nodes that are distributed throughout the network. Mesh topologies consist of many small, interconnected network segments called mesh links. Meshes provide connectivity between any pair of nodes without having to pass through a centralized hub.

6. Local Area Network (LAN)

A local area network (LAN) is a private telecommunications network covering a physical space such as a room, building, campus, or city. A LAN allows computing devices to share resources, including printers, file servers, modems, and scanners. Typically, these devices will belong to a single organisation or company; however, they may also be connected directly to the public switched telephone network or indirectly via a dialup connection. Most often, the shared resources are physically located alongside the devices that need them. While the concept of a LAN was initially used for connecting workstations, nowadays, a LAN is commonly used for interconnecting devices in homes and offices as well.

 7. VPN

A virtual private network is a secure virtual private network service that encrypts data transmissions across a shared or public network. A VPN creates a secure tunnel over a public network, such as the Internet, which enables users’ communications to remain private. The encrypted traffic appears to originate and terminate at different locations on the shared network.
