FEATURE 1

Organizing by layer and understanding the basics of network technology

Learning “Protocols” Systematically

 

In conjunction with the start of the new academic year and the arrival of freshmen, let’s analyze protocols, a subject that anyone who is looking to study networks must master. Protocols are the starting point for understanding networks. Getting a proper grasp of this core technology will definitely come in useful later on.

 

What are protocols?

The conventions and rules that make telecommunications happen

 

What does the “application layer” do?

It fulfills user needs through telecommunications

 

What does the “transport layer” do?

It links the client and server applications

 

What does the “network layer” do?

It carries data to the destination computer

 

What do the “data link layer” and “physical layer” do?

They convert the data into electrical signals and hand them over to directly connected machines

 

Beginners’ Question

Is there a difference between “session” and “connection?”

 

FEATURE 2

Acquire knowledge that can be used for 10 years

Vista and severs lead the way in 2008

Total Capture of New Windows Networks

 

Windows networks are widely used in LANs in offices and homes.  These Windows networks are to face a major turning point in 2008. This is because with the arrival of Windows Server 2008, it will become possible to make full use of next generation Windows networks in conjunction with Vista. It is likely that the existing world of Windows networks will also gradually be affected. Let’s be among the first to study the new Windows network functions which will become essential topics, and master knowledge that will come in useful for the next 10 years.

 

Part 1 - TCP/IP

Handling of IPv6 and optimization of TCP

Bottom up support with these two pillars

 

Part 2 - Windows Networks

Reworking the three major functions while keeping ongoing compatibility with past versions

 

Special Article

The larger the network delay, the more efficient the new protocols
