IT networking is the process of securely transferring data from one network to the next, giving access to the other IT administrator. In the world of Information Technology, networking is used to create, design, and use a network. Networks can also include routers, switches, bridges, routers, and hubs. Telecommunication protocol and Computer Software are used to manage and control the network in IT and to establish policies and procedures. The interfacing of two or multiple computing devices. The main purpose of connecting two computing devices in Information Technology, is to transfer and share data securely and completely.
Computer networks are built with both hardware and software. They can be classified in several ways, including:
1. Both Local Area Networks (WAN) and Wide Area Networks (LAN) are classified based on their geographical locations. A Local Area Network covers a small area that can be a school, home, or office. A Wide Area Network is spread across cities, countries, the world, and states. WAN is the largest category of internet coverage.
2.The Network Design, Client/Server, and peer-to-peer are the main categories of computer networks. These are the basic forms of network design. These two types are well-known for their functions and features. Client-server networks are centralized server computers that store email and Web pages. Files and applications can be accessed by clients and other client devices. Client servers are mostly used to store information in emails, files, web pages, and applications. Peer to peer networks use the same functions to connect devices. Peer to peer networks are best used at home. A business network might allow you to see information being shared from all devices and networks simultaneously, but a star network is a network that has a central device that allows information to flow from one device to all others. The centralized device is responsible to carry the information necessary for all networks. There are several types of network topologies that you might encounter, including bus, star, rings, mesh networks, and ring networks.
3. Protocols are the languages that computers use to communicate with each other. This is another way to classify computer networks based on the protocols they support. TCP/IP is the most popular protocol of networks. This language is most often found in home networks. Networks often have multiple protocols that support specific applications.
4. Home Computer Networking is an IT networking network that is primarily designed for homeowners. Home networking allows people to share and operate devices in different rooms of a house.
The Internet and networking have changed over time. In particular, after the introduction of the World Wide Web in 1990, Internet servers were used to share files, transfer data, and connect to one another across the globe in a deeper way. Public Websites and peer-to-peer (P2P) i.e. Peer to peer file sharing and hundreds of other services are now available on the internet servers around the globe. Over time, IT networking has seen significant improvements in its services. Networking has brought new technologies to users, as well as new languages, from wired to wireless internet. Both wired and wireless networks can use TCP/IP protocols. Internet networking courses are designed to give the candidate a basic understanding of networking systems. They mainly cover routing and switching. The CCNA course is the most popular IT networking course. The Cisco CCNA Cisco Certified Network Associate certification is a well-known, globally recognized IT certification. Candidates must prepare well and follow the guidelines to pass the Cisco exams. To qualify for the CCNA certification, one must score 200-125 on the cisco exam. Candidates receive a score report after passing the exam. It also includes a breakdown of exam sections and the passing score for that exam. Cisco does not publish exam passing score because exam questions can change at any time.
The CCNA exam is designed to test the candidates’ abilities and skills in installing, operating, and troubleshooting small-medium enterprise branch networks. The CCNA course covers many topics that will help the candidate gain a solid understanding of IT networking. These are the core topics of the IT networking course:
Connecting to a Wide Area Network (WAN)
Implementing network security
Types of networks
Network med
