Q211.

What are the two layers of I/O channels in Windows?

Low-level layer and high-level layer

Kernel layer and GUI layer

Device layer and subsystem layer

None of the above

Discuss

Answer: (a).Low-level layer and high-level layer Explanation:The I/O channels in Windows can be roughly divided into two layers: the low-level layer is the I/O system which is responsible for communicating with the hardware, and the higher-level layer is the Win32 subsystem, which is responsible for implementing the GUI and for processing user input.

Q212.

What is the I/O system responsible for in Windows?

Communicating with the hardware and managing device drivers

Implementing the GUI and processing user input

Storing and retrieving data from files

None of the above

Discuss

Answer: (a).Communicating with the hardware and managing device drivers Explanation:The I/O system is responsible for communicating with the hardware and managing device drivers running in the system and the communication between applications and device drivers.

Q213.

What are generic requests in the I/O system?

Basic tasks such as having a file system read or writing to a file

Requests specific to a particular device driver

Requests specific to a particular application

None of the above

Discuss

Answer: (a).Basic tasks such as having a file system read or writing to a file Explanation:Generic requests in the I/O system include basic tasks such having a file system read or writing to a file.

Q214.

How does the I/O system enable the creation of generic file system drivers and generic storage drivers?

By allowing multiple device drivers to be stacked on top of each other for each device

By implementing the GUI and processing user input

By communicating directly with the hardware

None of the above

Discuss

Answer: (a).By allowing multiple device drivers to be stacked on top of each other for each device Explanation:The I/O system enables the creation of generic file system drivers and generic storage drivers by allowing multiple device drivers to be stacked on top of each other for each device. This enables the creation of a generic file system driver that doesn’t care about the specific storage device that is used, and generic storage drivers that don’t care about the specific file system driver that will be used to manage the data on the device.

Q215.

What is the I/O system?

The subsystem responsible for implementing the GUI and processing user input

The combination of kernel components managing device drivers and communication between applications and device drivers

The component of the operating system responsible for communicating with the hardware

The layered system enabling the creation of generic drivers

Discuss

Answer: (b).The combination of kernel components managing device drivers and communication between applications and device drivers Explanation:A combination of kernel components that manage the device drivers running in the system and the communication between applications and device drivers.

Q216.

What are filter drivers?

Additional layers that monitor or modify the communications between drivers and applications or between two drivers

Drivers that register with the I/O system to enable applications to communicate with them

Components that perform processing on every file before it is sent to the file system

Drivers that don't care about the specific file system driver used to manage the data on the device

Discuss

Answer: (a).Additional layers that monitor or modify the communications between drivers and applications or between two drivers Explanation:Additional layers that monitor or modify the communications between drivers and the applications or between two drivers.

Q217.

What is the purpose of monitoring the I/O system for reversers?

To modify the communications between drivers and applications

To insert special filtering code into the device hierarchy

To extract information regarding the target program

To create generic data processing drivers

Discuss

Answer: (c).To extract information regarding the target program Explanation:Reversers monitor the I/O system "to extract information regarding our target program.

Q218.

What kind of I/O element can a monitored device represent?

Only a physical storage device

Only a file system

Only a high-level networking protocol

Any kind of I/O element, such as a network interface or a physical storage device

Discuss

Answer: (d).Any kind of I/O element, such as a network interface or a physical storage device Explanation:The device being monitored can represent any kind of I/O element such as a network interface, a high-level networking protocol, a file system, or a physical storage device.

Q219.

What determines the type of data received by a filtering component?

The position of the filter on the I/O stack

The type of device being monitored

The type of data being transmitted

The type of tool used to monitor the device

Discuss

Answer: (a).The position of the filter on the I/O stack Explanation:The position in which a filter resides on the I/O stack makes a very big difference, because it affects the type of data that the filtering component is going to receive.

Q220.

What is the Win32 subsystem responsible for?

Low-level graphics engine

Processing user input

Higher-level GUI constructs such as windows and menus

All of the above

Discuss

Answer: (d).All of the above Explanation:The Win32 subsystem is responsible for every aspect of the Windows user interface, including the low-level graphics engine, the graphics device interface (GDI), and higher-level GUI constructs such as windows and menus, as well as processing user input.
