What is IRQ?

What is IRQ?

• Internal Response Query
• Internal Request Queue
• Interrupt Request
• Increased Raise Quantity 

EXPLANATION

 

In a computer, an interrupt request is a hardware signal sent to the processor that temporarily stops a running program and allows a special program, an interrupt handler, to run instead. Hardware interrupts are used to handle events such as receiving data from a modem or network card, key presses, or mouse movements.

 

Such an input may be either "level sensitive" - the interrupt condition will persist as long as the input is active or "edge triggered" - an interrupt is signalled by a low-to-high or high-to-low transition on the input. Some processors have several interrupt request inputs allowing different priority interrupts.

What is FIFO?

What is FIFO?

• Foot Induced Foul Odor
• Flow In, Flow Out
• Fade In, Fade Out
• First In, First Out 

EXPLANATION

 

 FIFO is an acronym for first in, first out, a method for organizing and manipulating a data buffer, where the oldest entry, or 'head' of the queue, is processed first. It is analogous to processing a queue with first-come, first-served behaviour: where the people leave the queue in the order in which they arrive.

What's an FDD?

What's an FDD?

• Feature Driven Development
• Floppy Disk Drive
• Fault-Detection Drive
• Fierce Donut Dependence

EXPLANATION

 

A floppy disk drive, also called FDD or FD for short, is a computer disk drive that enables a user to save data to removable diskettes. Although 8" disk drives were first made available in 1971, the first real disk drives used were the 5 1/4" floppy disk drives, which were later replaced with the 3 1/2" floppy disk drives.

By 2006 computers were rarely manufactured with installed floppy disk drives; 3 1 ⁄ 2-inch floppy disks can be used with an external USB floppy disk drive, but USB drives for 5 1 ⁄ 4-inch, 8-inch, and non-standard diskettes are rare to non-existent. These formats are usually handled by older equipment.

Which one of the following is the trace route command for Windows?

Which one of the following is the trace route command for Windows?

• traceroute
• tr
• toonces
• tracert

EXPLANATION

  

 In computing, traceroute is a computer network diagnostic tool for displaying the route and measuring transit delays of packets across an Internet Protocol network. The history of the route is recorded as the round-trip times of the packets received from each successive host in the route; the sum of the mean times in each hop is a measure of the total time spent to establish the connection.

TRACERT. Trace Route - Find the IP address of any remote host. TRACERT is useful for troubleshooting large networks where several paths can be taken to arrive at the same point, or where many intermediate systems (routers or bridges) are involved.
