Computer routers came out in the 1980s and played a big role in linking devices and managing communication between networks. Important models from that time were the IBM PC Network router and the DEC router. These early routers were simple compared to what we have now, mainly doing basic tasks like packet filtering and static routing. Even though they were simple, they set the stage for future networking technology advancements.

In 1981, the first router was created to help different networks communicate. It worked by directing data packets. The router used the destination's IP address to find a match in its routing table, making sure data reached the right place. By the late 1980s, routing technology improved with dynamic routing protocols and multi-protocol routers. These improvements helped multiple networks communicate more effectively.

In the 1990s, routers became common for businesses and homes. They kept getting better with new features like NAT (Network Address Translation), DHCP (Dynamic Host Configuration Protocol), and later on, wireless technology. At TensorScience, we study how these technologies are crucial for modern machine learning. Today, routers do more than just connect devices; they are key for handling data-heavy applications. They help with strong and effective machine learning processes. As networks expand, routers will keep improving with even more advanced features.

Routers have a fascinating history, with many improvements over the years. They first appeared in the early 1980s and quickly changed and developed. The years when important routers were released are key points in computer hardware history. Here's a short list of these important moments:

• 1984: The OSI model was proposed, influencing router design.
• 1990: Cisco released its AGS router, a foundational product.
• 1999: Wi-Fi standards were established, leading to wireless routers.
• 2004: Introduction of the first dual-band routers.
• 2013: Launch of routers supporting 802.11ac standard.

In the 1980s, basic routers were created to link government and educational networks. These early routers were mostly hardware with limited features. The OSI model, introduced in 1984, helped standardize how routers should work with network protocols. As networks expanded, the need for improved and faster routers grew. Cisco emerged as a leading company in this field, especially with the AGS router released in 1990, which was popular for its reliability and capacity.

In the late 1990s, Wi-Fi technology changed routers from devices needing wires to those that could connect wirelessly. Wi-Fi standards were established in 1999, allowing wireless routers to connect several devices without cables. In the early 2000s, dual-band routers were introduced, which could use more than one frequency for better performance. By 2013, routers with the 802.11ac standard became common, providing faster speeds and improved range. Each new version brought features like better security and higher data transfer rates.

Computer routers have developed significantly over the years. In the 1980s, routers were quite basic compared to today. In 1981, ARPANET, an early network, used a new type of router that could connect different network types. This project was led by Stanford and BBN Technologies and was important because it improved data communication. In 1984, Cisco Systems released the first commercial router. These routers were more dependable and started to establish standards in the networking industry.

The 1990s brought about greater advancements in router technology. In 1994, the introduction of WAN routers by Cisco expanded their use beyond local networks. Network speeds increased and so did the functions of routers. The following are some notable events from that era:

• 1996: Cisco launched the 12000 series, which significantly boosted internet backbone speeds.
• 1998: The debut of the first home router started a trend towards home networking.
• 1999: Wi-Fi routers emerged with the introduction of the 802.11b standard, marking the start of wireless connectivity at home and in small offices.

In the early 2000s, routers became more advanced with the spread of broadband Internet. In 2003, the Linksys WRT54G series was launched, which was popular among developers because it could be customized with open-source software. Also in 2003, the IEEE 802.11g standard improved Wi-Fi speeds. In 2009, routers with the 802.11n standard came out, using MIMO technology to allow faster and more stable connections. These advancements helped build the routers we use today, which keep getting better and more complex.

In the next few years, changes are coming to router hardware. Wi-Fi 7 is expected to offer faster speeds and more reliable connections. As more devices need more data, routers must improve. The industry is focusing on trends like adding AI features, using more mesh systems, and adopting new frequency bands for better signal and less interference.

• AI Capabilities
• Mesh Systems
• New Frequency Bands

Routers with AI will get better. They will manage data traffic more effectively and fix network issues automatically. Users will have routers that adjust themselves for smooth connections. Mesh systems are becoming more popular too. They help several devices work together to cover bigger areas with stable connections. More homes and offices are using mesh systems for better network coverage.

Routers are getting better with new frequency bands that help reduce signal interference and increase internet speed, especially in busy places. Future routers are expected to have these advanced features in smaller designs. Companies are starting to use eco-friendly materials to make routers. This change not only enhances performance but also supports sustainability for people who care about the environment. The future of routers is likely to be smarter, faster, and more environmentally friendly.
