When an IRET instruction is executed what action takes place?
By ABDULLAH ABID Secretary Info & IT GLOBAL PEACE COUNCIL PAKISTAN. http://h.1asphost.com/gpcp/org The Interrupt-In-Service-Flag is set at the beginning of an interrupt-acknowledge cycle. It is reset by the IRET (Interrupt-RETurn) instruction. When IIS is set, interrupts are disabled. When the Status-register is read, IIS always reads as '0'.

What is the first microcomputer?
the first microcomputer is the altair 8080....but the first commercially available microcomputer is the apple II produce by the Intel Corp......=)
On most modern computers this means 65,536 bytes (8 bits) of random access memory, which can be both read and written.
On older computers this could mean a variety of different things depending on the architecture of the specific computer, some are:
- 65,536 words of random access memory, which can be both read and written. A word could be any number of bits in length, with values from 12 bits to 60 bits being most common. No entity smaller than a full word is directly addressable on these machines.
- 64,000 words of random access memory, which can be both read and written. A word could be any number of decimal digits in length, with values from 5 decimal digits to 12 decimal digits being most common. No entity smaller than a full word is directly addressable on these machines.
- 65,536 characters of random access memory, which can be both read and written. A character was typically 6 bits in length.
- 64,000 characters of random access memory, which can be both read and written. A character was typically 6 bits in length.
- 65,536 bits of random access memory, which can be both read and written. Any individual bit or group of bits (of any length up to 65,536 bits) is directly addressable on these machines.
- etc.
One really needs to be more specific with units to be unambiguous.
Why armour HT XLPE power cable required to Earth?
because when ever fault current occurs then the cable wont get damaged due to cable armored earthing to the gland for fault current to pass through groung
What component in a PC generates the most heat?
The newest CPUs and video systems generate the most heat.
Guided partitioning is an option in the installation of certain Linux distributions. It divides the hard drive into multiple partitions based on available space and typical usage patterns. Generally it does a tolerable job for single-drive machines, though anyone with previous systems administrator experience will probably do better, and certainly so for multiple-drive machines.
What are advantages power supply in computer?
The power supply converts the high voltage (e.g. 120VAC in US, 240VAC in Europe) alternating current house electricity supply down to the various different low voltage direct current supplies needed by different devices that make up the computer. These low voltage direct current supplies are tightly regulated in the power supply circuitry to prevent transients in the house electric supply from perturbing the computer's electronics as well as to compensate for variations in power demand as the different devices that make up the computer operate.
How do I download pictures from Fujifilm Camera to HP Computer?
When you bought your camera, there should be a CD. Just put your CD in your computer and there should be an easy setup. I, for one, did not do this and without thinking, I just plugged my camera in without the CD. DO NOT do this for the first time. Make sure you put the CD in first or else your computer will freeze up and it'll cost you a lot of money to fix it.
What is the Usb input signal for arrow keys?
User input signals are not defined within the USB specification.
If you had for example a USB keyboard running it would most likely send it's characters according to the ASCII table. This is how ever up to the manufacturer and if you can read the .dll file perhaps you will find out how it is done in your case.
The arrow keys in Hex according to the ASCII table;
Right 1C
Left 1D
Up 1E
Down 1F
Convert to binary, and use the USB protocol to transmit. In real life you will most probably have to also add stuff like headers and check-sums...
What do you do when your 98 Nissan Maxima vibrates and makes weird noises?
My 1996 Nissan Maxima started making weird noises, first it sounded like something was loose. The sounds were coming from the front tire area. I continued to drive the car for while and the noices just got worse. I was driving 50mph and it felt like the tires were going to fall off! I discovered the front L&R Stutts were shot! I had it fixed and now smooth as ever. Not sure if your weird noices are the same as my weird noises.

What good computer security programs for your computer are there?
This is what I have:
Avast!
Comodo Firewall
Spyware guard.
Spyware blaster
Real time protection in Spybot Search and Destroy.
Mvps Host file
Koffix blocker.
And maybe something else.
These are all to prevent!
This should make your PC really safe
On the other hand each of these are made by different companies and are not designed to work together. I use Avast Internet Security and it protects me from everything. There are a lot of advantages to using an integrated security suite.
What does Peripheral mean in a computer?
It is an item that can be attached to a computer that is not essential, such as a printer, scanner.
How should computers be used at work?
It largely depends on the goal of the policy. There are often security and compliance reasons for limiting what people do with technology such as e-mail (preventing electronic harassment, or the leaking of confidential information, for example). But often, the main goal is productivity and work-computer policies are created because employees are spending a lot of time surfing the Web for personal reasons. So you should use your work-computer for work-related things.
What are the advantages and disadvantages of using a graphic tablet?
