If you want to learn about computer networking, there are a lot of resources available. This guide will help you get started by explaining what computer networking is, and how it works. We’ll also go into detail on the OSI model, Ethernet protocols, data link layer protocols, IPv4 vs IPv6, and more.
What is Computer Networking?
Computer networking is the process of connecting computers together. These connections can either be wired or wireless, depending on the type of network you’re setting up. Computer networks allow users to share information, access resources remotely and communicate with each other across great distances–they’re essential components in everything from businesses to homes.
The most common type of computer network is called local area networks (LANs). A LAN connects multiple computers within close geographic proximity–typically within an office building or campus–to share data over a single connection point (like Ethernet cables). Another popular option is wide area networks (WANs), which connect multiple LANs over long distances using telephone lines or fiber optic cables; this allows people who work at different physical locations from one another to collaborate virtually as if they were all sitting in one room together!
Introduction to the OSI Model and TCP/IP
In this section, we’ll introduce the OSI model and TCP/IP. The OSI Model (Open Systems Interconnection) is a standard that divides computer networking into seven different layers. It’s also known as the DoD Model or ISO/OSI reference model. The TCP/IP protocol stack consists of four layers: application, transport, internet and link layer.
A typical TCP/IP header contains 20 bytes of data; however, only 14 bytes are used for actual data transmission purposes while the remaining 6 bytes are reserved for future use by other protocols such as IPv6 (Internet Protocol version 6). A typical packet size may vary from 64 bytes up to 1500 bytes depending upon whether it contains only headers or contains both headers plus payloads (i.e., actual data).
Ethernet Protocols–What is Gigabit Ethernet?
Gigabit Ethernet is a type of Ethernet that supports data transfer rates of 1 gigabit per second (Gbps).
Gigabit Ethernet also goes by the name 1000BASE-T, and it’s the most common type of Ethernet used today.
Data Link Layer Protocols–What is Spanning Tree Protocol?
Spanning Tree Protocol (STP) is a protocol that creates a loop-free topology for Ethernet bridges. STP prevents bridging loops by blocking redundant links and enabling only one path between any two network segments.
Bridges communicate with each other to learn their neighboring devices on the same network segment, then they exchange information about which ports are available to forward packets.
How does an IP address work?
IP addresses are 32 bits long, each bit is a number from 0 to 255. Each byte of an IP address is divided into two parts: the first part is called the network part and the second part is called the host part.
The network part identifies all devices on a specific network (or subnet), while each device’s unique identifier within that subnet resides in its host ID portion of its IP address. So when you’re setting up your home router or computer at work, it’s important to know which subnet they belong to so you can find them easily later!
ARP and RARP in the routing table.
The ARP protocol is used to find the MAC address of a host on the same subnet. RARP is used to find the IP address of a host on the same subnet.
In IPv4, ARP operates at layer 2 (Data Link Layer) where it uses Internet Protocol Version 4 (IPv4) packets as its payload and broadcasts them over Ethernet networks to find out which device has what IP address? This process is called Address Resolution Protocol (ARP). It helps in resolving addresses such as 192.168.1.10 into physical hardware addresses like 00:00:00:00:00:01 which are called Media Access Control (MAC) addresses in networking terminology.
In case of IPv6 network protocol suite, each node has two addresses; one for routing packets within an intranet or local area network (LAN), another one that can be used for accessing Internet resources such as websites or email servers located outside your company firewall but still within reachable distance through wireless signals transmitted by mobile phones etcetera..
IPv4 vs IPv6, IPv4 header format, transport layer protocols and ports.
The Internet Protocol, or IP, is the protocol that defines how data is transmitted over a network. There are two versions of this protocol: IPv4 and IPv6. The main difference between them is their header format; IPv4 uses 32 bits while IPv6 uses 128 bits. A header includes information about where packets are coming from and going to, as well as other information such as port numbers (used by applications on computers) and transport layer protocols like TCP/UDP (transmission control protocol/user datagram protocol).
If you want to learn about computer networking, there are a lot of resources available.
- Online courses: The best way to learn is by taking an online course. This can be done through MOOCs (Massive Open Online Courses), which are free, or paid courses.
- Books: There are many books available on the subject of computer networks and networking that you can purchase from Amazon or your local bookstore.
- Videos: There are also many videos available online that teach different aspects of this topic. These can be found on YouTube, Udemy, Lynda and more! * Tutorials: If you prefer hands-on learning then tutorials might be more suited for your needs! There are plenty out there but we recommend checking out Learn How To Network Like A Boss which teaches everything from cabling through routing & switching
