The term “tech guy” became popular in the late 80s when technology was making its entry into different fields. Today, it is a common term referring to someone who has a high proficiency in digital technology. The tech guys have a technical mind and break things down and work through them in an orderly fashion. Starting from cloud applications, and software delivered as a service requires the skills and knowledge of tech guys.
Even when the job doesn’t demand software development, the tech guy must understand the ways applications are developed and the entire cycle involved. The tech guys are IT and computer experts who are trained in programming languages as a part of their academic learning. The basic C-based programming languages, some basic Python, and Visual Basic are expected by the tech guys to know. The fundamentals of basic languages and the logic behind the way data is stored helps to proceed efficiently in a tech project.
Basics of networking
The network indicates how every aspect of technology connects, and every IT professional should be aware of how it happens. Computer networks include multiple devices and mediums that aid in the communication between two distinct network devices, like hubs, routers, bridges, and switches. These are vital network basics that help communicate with one another and also other networks, like the internet. The tech guys might not have to handle such matters daily, but they must know about the basics of networking and the devices necessary for connection.
Knowledge about IP addressing
The root of every online communication is the IP or Internet Protocol. Furthermore, the basis of every IP communication is IP addressing. Knowing how IP addressing functions is key for tech guys. Every host, server, firewall, router, network device, etc., must include IP addresses to communicate with other IP devices and hosts. When incorrect IP addresses are assigned, the device or network hosts fail to communicate and also harm existing devices.
Know-how about packet sniffing
Packet sniffing is a network tracking tool designed for network troubleshooting. Before one uses it, it is important to understand the ways of setting it. It is necessary to understand the effect of the Network Interface Controllers, or NIC, on performance and accuracy. Furthermore, a tech guy must know how to use a SPAN or Switched Port Analyzer port over TAP (Test Access Point) and vice-versa. A tech guy must also understand the multiple starting options and the configuration process.
The corporate world consists of tech guys who have to deal with complex data, security, connectivity issues, and other applications regularly. Similar to other industries, the tech industry has multiple sub-specialties. No matter which technology field one is working in, several skills are necessary for such professionals. They are not only knowledgeable and skilled in the field, but their passion and dedication for technology are beyond any description. This is what makes them so unique. Knowledge of the above-mentioned skills helps tech guys carry out their tech-related responsibilities efficiently.
