Networking Basics: Learn Everything About Computer Networking [Updated 2024]

Networking Basics will let you experience the best way to deal with online threats coming toward your networks. But how? For that, this article will explain everything from the basics to advance ones. Many of us don’t know about how the network crisis happened.

Because of that, issues such as follow happen. Let’s talk about what is a computer network, what its types are, and how a computer network works. Keep reading!

What is a Computer Network?

In this article, we’ll be talking about the Basics of Computer Networking. It’s a system allowing several PC, devices & networks to provide communication and data transmission facilities to the users. Moreover, one will be able to offer to follow access.

  1. Exchange Data,
  2. Access Shared Docs & Facilities, and
  3. Connection Building.

Here are some key aspects of networking:

  1. Network Components

It consists of the following components.

  1. Computers,
  2. Servers,
  3. Routers,
  4. Switches,
  5. Modems, and
  6. Network Cables or Wireless Connections.
  7. Network Topologies

It’s about the physical/ logical layout of the device in a network. Moreover, the usual ones involved.

  1. Star,
  2. Bus,
  3. Ring, and
  4. Network Protocols

These are sets of rules & standards that regulate data transmission, formation, and processing in a network. With the help of these, the network determines.

  1. Addressing,
  2. Data Integrity, and
  3. Error Detection & Routing.

One of the most preferred protocols is TCP/IP for internet communication.

  1. IP Addresses

These are unique numerical identifiers that are allotted to devices on a network. It facilitates the routing & delivery of data across the network.

  1. Subnetting and Subnet Masks

The Subnetting includes network division into smaller subnets. There, the Subnet masks allow the selection of network & host portions of an IP Address. Subnetting keeps things neat and tidier for efficient network management and addressing.

  1. Routing

It’s responsible for the transmission of data packets from source to destination around several networks.

  1. Switching

It connects systems within a range of networks & facilitates communication. Moreover, they use MAC addresses to move data packets to the destined destination.

  1. Network Security

It focuses on securing networks, data & devices from online access/ threats. Moreover, it included.

  1. Firewalls,
  2. Encryption,
  3. Authentication,
  4. Access Controls, and
  5. Regular Security Updates.
  6. Network Address Translation (NAT)

It allows devices to communicate on a private network with a single public IP Address. Moreover, that helps in translating private IP to Public IP Addresses, which improves network security & conversing IP Addresses.

  1. Wireless Networking

It uses tech such as Wi-Fi to allow devices to connect & communicate without a wired connection.

Types of Enterprise Computer Networks

S.No. Types Define
1. Local Area Network (LAN) It covers a small area, such as a building/ campus, while connecting devices in a limited area allows sharing of resources, such as.

a) Files,

b) Printers, and

c) Internet Access.

2. Wide Area Network (WAN) It is spread around a huge area while connecting several LANs & locations. Moreover, it uses tech such as.

a) Leased Lines,

b) Satellite Links, or

c) Internet Connections.

3. Metropolitan Area Network (MAN) It covers a huge area than LAN, however, it is smaller than WAN while connecting several LANs within a city.
4. Virtual Private Network (VPN) It’s a secure network connection that allows remote users to access the internet with

a) Encrypted Communication,

b) Ensuring Confidentiality and

c) Security for Data Transmitted between locations, remote users, and the corporate network.

5. Wireless Local Area Network (WLAN) It uses wireless tech, such as Wi-Fi, to build connections within a limited area. Moreover, it makes it easy for the users to connect with each other without a wired connection.
6. Storage Area Network (SAN) It’s a customized network for storage & data retrieval allowing several servers to access shared storage devices that are over a fast network connection, such as.

a) Disk Arrays, and

b) Tape Libraries.

7. Campus Area Network (CAN) It’s a network that makes connections with several LANs within an institute. Moreover, it comes with high agility.
8. Cloud Network It is a network infrastructure connecting a firm’s on-premises network to cloud services allowing firms to access & use

a) cloud-based applications,

b) platforms, and

c) storage seamlessly.

How Does a Computer Network Work?

  1. Network Architecture

It involves

  1. Physical Outlet of Devices,
  2. The logical organization of network components, and
  3. The protocols.
  4. Network Devices

It involves routers & switches allowing the flow of data among devices within the network. Where the router builds connections between various networks, the switches allow communication among devices within the network.

  1. Data Transmission

Data Transmission needs the distribution of data packets. Each one consists of a huge amount of data with IP addresses. It travels via a network from source to destination.

  1. Addressing

Each device connected to the network has a unique IP Address as an ID, ensuring that authorized users get the data sent by the sender.

  1. Routing

Routers test the IP in the packets & choose the best path for the packets to reach the point.

  1. Switching

The switches connect devices within the same network. With the use of MAC addresses, it moves packets to the destination. After receiving the packet, the switch test the destination MAC address and moves the packet to a certain destination.

  1. Protocols

These define rules and regulations for communication within a network. It depends on the protocols how

  1. Devices Establish Connections,
  2. Format Data Packets,
  3. Handle Errors, and
  4. Ensure reliable delivery of data.

Usual protocols include

  • TCP/IP (Transmission Control Protocol/Internet Protocol),
  • Ethernet,
  • Wi-Fi, and
  • DNS (Domain Name System).
  1. Network Services

These offer various facilities, such as

  1. File Sharing,
  2. Printing,
  3. Email,
  4. Web Browsing, and
  5. Remote Access.
  6. Security

Network security is important to secure data & prevent unknown access. Some of the security measures are as follows to secure networks & reduce risks.

  1. Firewalls,
  2. Encryption,
  3. Authentication, and
  4. Access Controls.
