Introduction to Hardware and Networking course

Congratulations on showing interest or completing one of the most popular and  developing domains of IT. If you are interested in knowing more about how Hardware and Networking course will help you fetch a stable job in IT field , please keep reading.

Let us begin with understanding the basics of Hardware and networking:

Computer Hardware is the combination of physical components or parts that makes the computer system. Physical components include monitor, keyboard, mouse, hard disk drive, graphic card, RAM, motherboard, etc.

Networking is the field of computer science that allows computers to exchange data or information. Data can be exchanged either using cable media or wireless media.

Internet is one of the best example of Network.

Now, that we have understood basic definition of Hardware and Networking, let us understand the career prospects , programs which will help you gain in depth knowledge of the aforesaid topics.

There are more than 2.5 billion devices currently connected to the internet, with almost 8 new internet users being added every second worldwide. If this does not amaze you, it is estimated that by 2020, more than 200 billion sensors will come online and report their data seamlessly over the internet. With such a rich ecosystem, the internet needs to be very rigid, well planned and structured.

All the computer devices are called hosts or end systems. Hosts sending requests are called clients while hosts receiving requests are called servers. End systems are connected together by a network of communication links and packet switches. Communication links are made up of different types of physical media, including coaxial cable, copper wide, optical fiber, and radio spectrum. Different links can transmit data at different rates, with the transmission rate of a link measured in bits/second. When one end system has data to send to another end system, the sending end system segments the data and adds header bytes to each segment. The resulting packages of information, known as packets, are then sent through the network to the destination end system, where they are reassembled into the original data. A packet switch takes a packet arriving on one of its incoming communication links and forwards that packet on one of its outgoing communication links. Common packet switches are routers and link-layer switches.

Internet Protocols

End systems, packet switches and other pieces of the Internet run protocols that control the sending and receiving of information within the Internet. The Transmission Control Protocol (TCP)and the Internet Protocol (IP) are two of the most important protocols in the Internet. The IP protocol specifies the format of the packets that are sent and received among router and end systems. The Internet’s principal protocols are collectively known as TCP/IP.

Given the importance of protocols to the Internet, it’s important that everyone agrees on what each and every protocol does, so that people can create systems and products that interoperate. Internet standards are developed by the Internet Engineering Task Force (IETF) into documents called requests for comments (RFCs). RFCs tend to be quite technical and detailed. These define protocols such as TCP, IP, HTTP, DNS and SMTP. There are currently more than 6,000 RFCs.

Layered Architecture

Internet Protocols are organized in a layered architecture. To explain this, let’s imagine you are trying to look for a meme from Google’s image search. The server has the image of your choice stored. Before the server sends out that information, it needs to convert that image into a package with all the necessary headers. Once it reaches the client, the reverse takes place. The packets have their headers removed in the reverse sequence and then converted back to the original data. .

Now that we have understood the foundation of how Hardware and networking works, Let us now know why hardware networking will offer you plethora of opportunities to make career in flourishing IT filed.

Great Opportunities For International Exposure : Most networking standards are global. If you are a networking professional with CISCO and RedHat are international certifications with wide reach and are valid and in demand pretty much everywhere. CISCO is one of the leading manufacturers of network and computer hardware and a CISCO certifications works like magic at most places due to the brand name.

Diverse Career Prospects : Once you are Hardware & Networking graduate you will have a huge option of jobs from field technician to network engineer to network operations analyst. In fact passing out from a reputed institute like Sandgrouse Technologies, Bengaluru with a degree in hardware and networking pretty much makes you eligible for many jobs in many industries as all industries in today’s time are in need of an efficient and fully functional network system.

If you are looking for a high quality yet affordable Hardware & Networking degree then you can consider the course in Hardware & Networking offered by Sandgrouse Technologies. Unique features of this course includes international certifications from CISCO and RedHat and also there’s a pre placement team which trains the graduates in essential soft skills to help them crack interviews with ease.

While we are understanding the basics of the course and the opportunities that this ever evolving IT program will offer us, let me unravel more details in my next post. Till then, keep reading and stay informed.
