Networking with Microsoft Windows

Q1. What is Next Generation TCP/IP stack?

• Next Generation TCP/IP is a new implementation of Transmission Control Protocol/Internet Protocol (TCP/IP) functionality for Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) to meet the connectivity and performance needs of today's networking environments and technologies. The features of the Next Generation TCP/IP stack include support for dual IP layer architecture for IPv6 and strong host model. In addition, it provides new packet filtering Application Programming Interfaces (APIs) and mechanisms for protocol stack offload. 

Q2. What is the role of Explicit Congestion Notification (ECN)?

• When routers become congested, the incoming packets fill the buffer, which in turn begins dropping packets. In such a case, ECN for TCP/IP provides a way for routers to inform TCP peers that their buffers are filling due to the congestion in a network and force them to slow their transmission of data to help present packet losses. 

Q3. Is IPv6 enables by default in Windows 2008?

• Yes

Q4. Can you uninstall IPv6 in Windows 2008?

• No, however, it can be disabled.

Q5. Which component makes it possible to use multiple protocols on computer?

• Transport Driver Interface makes it possible to use multiple protocols on computer.

Q6. What do you mean by unbinding the protocol?

• Unbinding the protocol prevents a network interface adapter from using one of the installed protocol modules on the computer.

Q7. Which component connects to the remote source of data, downloads the file, and passes it back to Windows?

• Redirector has the knowledge on how to connect to the remote source of data, download the file, and pass it back to Windows, which in turn passes it back to the user or the program.

Q8. What is the role of Server Manager in Windows Server 2008 R2?

• Server Manager helps administrators through the process of installing, configuring, and managing server roles and features that are part of Windows Server 2008 R2. It provides a single location for administrators to change the server's system properties and install or remove roles of features.

Q9. What is Windows Powershell?

• Windows Powershell is a command-line shell and scripting language to achieve greater productivity and make control system administrator easy. It accelerates automation of system administration easy. 

Q10. Which service helps in setting up new computers by using a network-based installation?

• Windows Deployment Service.

Q11. Name the tool used to monitor and assess system performance and reliability?

• Windows Reliability and Performance Monitor. It provides a Graphical Interface for customizing performance data collection and Event trace sessions.

Q12. What is Interrupt Request Line (IRQ) used for?

• IRQs are hardware lines over which hardware devices send the interrupt signals to the microprocessor.

Q13. What is input/output (I/O) port address used for?

• I/O ports are those sections of memory that the hardware devices use to communicate with the operating system. When a microprocessor receives an IRQ, the operating system checks the I/O port address to get details of the hardware device that has triggered the communication.

Q14. What is Direct Memory Access?

• DMA is a feature of computers and microprocessors that allows disk drive controllers, graphic cards, network cards, and sound cards within the computer to access system memory for reading and/or writing independently of the CPU

Q15. How does a Plug and Play device automate the hardware installation process?

• When a Plug and Play device is connected to the computer, a new hardware is detected by the computer and it searches for the driver, which is then installed, and configures the hardware to use the system resources.
