What is response time in real time system and What is the difference between response time and execution time in real time system?

response time is the time in which our system respond us back, i.e. the system

gives us the result of our input at what rate.. and execution time is the time taken by the system to complete the input... if the response time of our system is high then the performance of the system is not accurate..

Are there magnets inside a computer?

No. The only parts that deal with magnetism are some kinds of storage, such as floppy disks, traditional hard drives, and tape libraries. However, some desktops and laptops are now shipping with SSD storage and are completely unaffected by most magnetism. Extremely strong magnetic fields are capable of interfering with any electrical system, however.

What are Infrared rays used for?

Infrared light has a number of applications. In fact, some animals can sense infrared light, which make it easier to catch prey or to see under poor lighting. Infrared has a number of heating applications, such as being used to cure certain adhesives. There are experiments being done which involve using near IR light to promote healing.

Infrared light is what common television remotes use. The signals are modulated in how the IR light is pulsed, so that is how the different buttons on the remote are distinguished.


Some other applications include meteorology, communications, climatology, astronomy, art conservation, imaging, and missile guidance, among others.

What is a group of two or more computer systems linked together in the same building called?

Can computer damage caused by a magnet be reversed?

Actual damage by a magnet to a computer is extremely rare, and thus it is impossible to gauge what type of damage you are referring to. Data erased from a disk by a magnet is likely not recoverable. You should be able to reinstall the operating system to the disk, but depending on the intensity of the magnetic field, the disk may need a passover with a degaussing coil to remove a strong magnetic field.

Magnetization to a CRT monitor (generally resulting in distorted colors) can usually be fixed by running the monitor's built-in degaussing coil (selectable in its OSD menu). A particularly strong field may require several degaussing sessions (the coil built in can only be run once every five minutes or so), or require the use of a dedicated degaussing coil. Any television technician should have such a coil.

How software makes computer slow?

This is a very hard question to answer because there are a lot of factors that can contribute to a computer running slow. I'm not a computer technician but in my estimation from my experience with computers the most likely reasons would be:

1. Spywares or Viruses

2. Programs running in the background eating up your computer resources.

3. You are running programs too heavy for your computers capabilities, thus overloading it and causing it to run slow.

In 90% of the cases its Spywares or some Virus. You can sometimes spot if you have a spyware eating your memory from the Task Manager and closely surveying what programs are eating the most resources and if they are indeed something you yourself have installed or something unknown.

How do you earth a computer?

Most home or commercial building wiring uses 3 prong power outlets. One of the pins on a plug SHOULD be the ground/earth wire.
If the power cable was created properly, the computer should be properly grounded (earthed) when it is connected to the main power through that plug...
HOWEVER
If there is any doubt as to whether your power outlet has a built in ground connection, you can connect a single (12 GA or 14 GA) wire to an iron or copper pipe in the home or drive a grounding rod into the ground outside the home and connect the wire to that. Run the wire to the computer and place a crimp-on lug to the end of the wire, then connect it to the computer chassis using one of the screws on the back of the computer.
