What are the disadvantages of real time information?
Real time information is data that is made available to you in real time, i.e. as it happens. For example, a system which monitors incoming flights on a given airport might transition an incoming flight through states like "in the air," "on approach," "landing," "landed," "at gate," "awaiting bags," "bags in hall." In a real-time system, the status of each flight would change as it happens, or within a short time after the event. An alternative, not real-time, approach to such a system would be to update the status of all flights once every five minutes, for example.
Real-time information has no disadvantage per se, but most end-users would expect that any system in-between the data source and the consumer (e.g. a display of incoming flight status in the arrivals hall) can cope with the demands of real-time data.
This requires that all components relaying this data, and acting on this data, must be able to handle this data in real time, i.e. in a manner such that the accumulated processing delays remain negligible. Depending on the nature of the data, on the processing requirements and the frequency of change, this can have severe design implications for the participating components.
In modern banking, the availability of real-time information is widely accredited with several financial crisis that occurred within the past decade: since brokers could see transactions and rate changes in real time, responses were much faster as they would have been with slower data. This allowed to hectic response and panic reaction, leading to severe financial crisis in several stock and currency markets.
What are the uses of computer in the media houses?
in media we use the computer for reporting and analyzing the news about the people in our community
Which type of input device would you choose if you were going to play a shoot 'em up'computer game?
I would use a joy stick if i had to. But i think that it would be cool because it would be a lot easier.
How do you print to hp officejet 4650 from computer?
what you do is to connect all wires to your computer, then you have to go to what ever you are printing from, wrd,excel etc. then hit print. make sure printer is on and make sure there is ink in there. and that should work.
PDAs are also known as what type of computers?
no there not there more of personal organsers. stands for "personal digital assistant"
What are the benefits of computer monitor mounts?
A computer monitor wall mount clears up space on the desk. Your computer monitor hangs on the wall, which adds a little more space on your desk, which can be more convenient for people with small computer desks.
Is technology killing the society?
Many people believe that technology is killing society as people know it. With the increase in technology, there has been a decrease in things like camp outs or picnics,Êwhich required actual face time with other people.
What is the full form of IRC in computer?
Internet Relay Chat
Internet Relay Chat (IRC) is a form of real-time Internet chat or synchronous conferencing. It is mainly designed for group communication in discussion forums called channels, but also allows one-to-one communication via private message, as well as chat and data transfers via Direct Client-to-Client.

What do you call a person who knows how to use computer?
The person who uses computer is called USER.User is also the term used in GRAPHICAL USER INTERFACE.
What is the importance of computer in engineering?
Engineering is one of successful professionals in the world which can receive a big amount of salary. Traditionally, engineers used their hands to draw to make a layout of their product but it consumes a large time, and now engineers used computer to create a layout with much greater result.
How do you covert watts to amps?
Watts = current x volts, so you have to multiply Kw value by 1000 to get watts, then divide by the applied voltage. examples.
2Kw kettle (U.S) current = 2 x1000 divided by 120, or 16.7 amps
2Kw kettle (UK) current = 2 x1000 divided by 240 or 8.35 amps
100 watt car amplifier current = 100 divided by 12 volts = 8.5amps
Is there any websites where you can talk to your friends on a school computer?

A router will direct data flow around a network. The microprocessor at the heart of a computer directs data flow within a computer system and provides a way for the user to interact with the computer
How do you think restricted air flow affects a computer's performance?
this is because as you use a computer certain parts ( for example the CPU) starts to heat up, and this does affects the computers performance as it has a range of temperatures in which it (the CPU) can optimally work, when are flow is blocked, it causes it to overheat, this makes it hard for it to work properly, hence affecting computer performance. most computers will automatically shut down if certain parts overheat, to prevent injury and damage ( to computer parts).
What is exhaust fan in computer?
An exhaust fan is a system fan that blows (usually warm) air out of the computer.
Semiconductors that are used in computer and calculaters?
Calculators are amazing devices used for quick calculations.
They use semiconductors in two places:
-- in chips (widely known)
-- in display
A circuit board to perform calculations employ transistors, FETs, diodes, etc. These are made up of semiconductors.
Next, the important part is display which used Liquid Crystal Display. In modern day calculators, Twisted Nematic crystal display is used where voltage changes must be made to increase or decrease the amount of light passing through them to create numbers. Instead of using different plates for the 7 segments and supplying separate voltage for each of them, a single plate is used and semiconductor in the form of FETs is embedded in glass so that voltage of every segment can be controlled by the semiconductor device and a common voltage source can be used. Nowadays, calculators form characters other than numbers which requires only a selected area to be supplied with voltage. This is accomplished using semiconductors.
Why have computers became an important research tool?
Over time, computers have become important research tools. First, they began to replace encyclopedias, maps, atlases, and microfiche with CD-ROM versions. Then as the Internet became popular, encyclopedias moved to a subscription format. That way, you didn't have to own a set of bulky encyclopedias, and the information would always be up to date.
Of course, the Internet replaces a lot of periodicals too and enables ordinary people to have access to medical journals, law books, newswires, and lots of other information. It also helps with more informal education too. If you need to access original research or niche information that few have heard of, you will likely be able to find it online.
Why your laptop is running so slow?
First, make sure there are no unwanted background processes such as spyware. They can take your system to a crawl speed. Use a tool such as spybot to detect and remove spyware. Next, make sure all of your anti-virus software is up to date and that you have all of the definitions current. Last, make sure you have enough physical memory. Loading a lot of applications can tie up memory and you can end up "swapping" a lot of data to disk and that takes time.
Describe different types of input devices in a robot with examples?
If depends on what robot but most inputs would be telling it what to do! E.g. for a robotic crane the input would be to move down a certain degree, then up and then turn. The Outcome then being an object moved!
The temperature inside the case should not exceed degrees C?
This will generally depends on the components of your computer and what it's tolerances are. Some cases will commonly get to 100+ degrees F inside and others are layered with fans and such to keep the temp down.
As a rule, don't let it go much over 100 degrees F. If it's that hot in the air, it's reaching bad temps on your motherboard and various components.
How do you fix a crashed computer?
This depends entirely on what needs to be fixed. Computers are incredibly complex and when things go wrong it may not be clear what the problem may be. If you have a problem with your computer, the best way to get a solution is to accurately describe your problem to a professional or even someone who is well-acquainted with the workings of computers.
When i go to fix a computer i bring my hands with me (it helps).
1 gb = 1024 megabytes
so if you want to get the answer to how much megabytes are in 500 gigabytes, you would just have to do simple multiplication
500gb x 1024mb = 512,000 megabytes
512,000 megabytes is equal to 500 gigabytes
What are the benefits of using a computer hideaway desk?
The benefits of using a computer hideaway desk are that you can keep your work items close to you - your computer, work papers, etc., without having an entire room dedicated as an office. They are also easy to manage - items are stored in drawers that are easy to open and close, allowing you to reach important items easily.
Can too many cookies slow down your computer?
Cookies do not slow your computer down.
Too many cookies or temporary internet files might slow down a badly-written web browser (possibly some versions of Internet Explorer).
Accessing a cookie on a badly fragmented hard disk may also slow your web browser down (much like pulling a book from a bookshelf that is alphabetized versus finding a book in a pile of books).
But they CANNOT slow down the computer in general. Only your web browser ever looks at this data.
(Your computer might behave badly if it runs out of disk space. If you are out of disk space deleting temporary internet files might free some up. The cookies don't take up much space though.)
