A computer handles several interrupt sources of which the following are relevant for this question. Interrupt from CPU temperature sensor (raises interrupt if CPU temperature is too high) Interrupt from Mouse (raises interrupt if the mouse is moved or a button is pressed) Interrupt from Keyboard (raises interrupt when a key is pressed or released) Interrupt from Hard Disk (raises interrupt when a disk read is completed) Which one of these will be handled at the HIGHEST priority?
There is a numeric lock which has a 3-digit PIN. The PIN contains digits 1 to 7. There is no repetition of digits. The digits in the PIN from left to right are in decreasing order. Any two digits in the PIN differ by at least 2. How many maximum attempts does one need to find out the PIN with certainty?
Is there an SDA pin on the RFID Module?
An Internal combustion engine has a connecting rod of mass 2 kg and the distance between the centre of crank and centre of gudgeon pin is 25 cm. The Center of Gravity lies at a point 10 cm from the gudgeon pin along the line of centres. The radius of gyration of this system about an axis through the Center of Gravity perpendicular to the plane of rotation is 11 cm. If two masses are used instead of the connecting rod, one at the gudgeon pin and other at the crank pin. What will be the new radius of gyration?

If two masses are used instead of the connecting rod, one at the gudgeon pin and other at the crank pin, if the angular acceleration of the rod is 23 000 rad/s2, then find the correction couple in N-m.

The following sentences form a paragraph.They are numbered as P, Q, R and S. These four parts are not given in their proper order. Read the sentences and choose the alternative that arranges them in correct order. P. It uses radio frequency identification (RFID) technology to make cashless payments through a prepaid account linked to it. Q. The tag, which is valid for five years, comes in seven different colours — violet, orange, yellow, green, pink, blue, black. Each colour is assigned to a particular category of vehicles. R. A FASTag is a reloadable tag that automatically deducts toll charges and allows a vehicle to pass through a toll gate without stopping for the payment. S. The tag is fixed to the windscreen of a vehicle and an RFID antenna in the canopy of the toll gate scans the QR code and the tag identification number, following which the boom barrier lifts to allow a vehicle to pass through.
A microprocessor accepts external interrupts (Ext INT) through a Programmable Interrupt Controller as shown in the figure. Assuming vectored interrupt, a correct sequence of operations when a single external interrupt (Ext INT1) is received will be :
Consider the following statements: The 8259A Programmable Interrupt Controller can 1. Manage eight interrupts 2. Vector can interrupt request anywhere in the memory map 3. Have an 8-bit or 16-bit interval between interrupt vector locations 4. Be initialized with operational command words Which of the above statements are correct?
In a microprocessor, the service routine for a certain interrupt starts from a fixed location of memory which cannot be externally set, but the interrupt can be delayed or rejected. Such an interrupt is
