You are installing a network interface card on a computer with the following configuration: a 5867133 CPU, 16MB or RAM, a 800-MB IDE hard disk, a parallel port configured as LPT1, and a serial port configured as COM1, which is currently used by a mouse. In addition to the IDE host adapter and the video card, the following devices have been installed on the computer's expansion bus: a modem on COM2, a SCSI host adapter for a CD-ROM drive, and a sound card. The SCSI hose adapter is using IRQ 5, and the sound card is using IRQ 11. The network interface card that you are installing supports the following choices for IRQ: 2, 3, 4, 5, 9,10 and 11. Which IRQ(s) could you use for the network interface card without creating an IRQ conflict with another device?
Based on the paragraph given below answer the following question: The traditional methods of combinational circuits involve simplification and realization using gates. Using these methods, complex functions have been integrated and are easily available in IC form. There is an attractive array of devices like a multiplexer, demultiplexer, decoders, comparators, parity generators/checkers, which significantly reduce IC package count there by reducing the system cost. The system design is greatly simplified because the laborious and time-consuming simplification methods are generally not required with these devices. This also improves the reliability of the system by reducing the number of external wired connections. But they have some limitations as well. Different memories like ROM, PROM can also be used to implement combinational circuits without much simplification.   A ROM is to be used to implement a “Squarer”, which outputs the square of a 3-bit number. What must be the size of the ROM?
You have an interface on a router with the IP address of 192.168.192.10/29. Including the router interface, how many hosts can have IP addresses on the LAN attached to the router interface?
Just for a simplicity consider a pure substance B. By analogy with the migration of a high-angle grain boundary the net flux of B across the interface will produce an interface velocity v given by____ (Interface mobility is given as M, Molar volume V, and the driving force is given as Δμ)
At the interface between two linear dielectrics (with dielectric constants $${{\varepsilon _1}}$$ and $${{\varepsilon _2}}$$), the electric field lines bend, as shown in the figure. Assume that there are no free charges at the interface. The ratio $$\frac{{{\varepsilon _1}}}{{{\varepsilon _2}}}$$ is

In Java, which keyword is used to implement inheritance between classes?
It is better to implement the PreparedStatementCreator interface and other callback interfaces as inner classes if they are used within one method only.
