What is neurocomputing?

Neuro computing is a field of computing (processing, designing, problem solving etc. ) using the models that simulates (human) nerves system. The basic component of a human nerves system is neuron. Typically humans have millions and billions of neurons working in parallel, asynchronous and distributed fashion. Area such as artificial neural network facilitates models such Hopfield, Perceptron and Self-organizing map (SOM -Kohenon) ) and various learning algorithms in supervised and unsupervised manner. Using these models human like computing can be achieved to fulfill aim of embedding intelligence into machines such as computers/ microprocessor chips.

How do you unlock a Microsoft 2007 document?

First, click on any other open Microsoft program to see if there is a dialogue box open.

When I posted this question, a dialogue box that was open in Excel turned out to be the culprit for Word thinking the document I wanted to open was in use by 'another user.'

I simply exited the dialogue box in Excel, and then was able to open the Word doc without issue.

When hooking up s video on compaq laptop to the tv and when you play movie on your tv screen and there is pictures but no sound how do you get sound to work when using s video to tv?

Good Question,

Ready here you go......You got to pick up a wire with a headphone jack on one end and a dual RCA plugs on the other end. Then if you have a audio input connection on the back of your tv you plug it in or in to a input channel on your receiver and select that channel when you power it on. Afterwards look for the little headphone logo with the jack underneath it and plug in your headphone plug. You may want to lower the volume on the laptop and on the TV or Receiver and adjust the sound output. Follow these same steps with your IPOD or MP3 Player, Blackberry Phone to stream your tunes. The wires range from 99 cents, I have gotten lucky at the dollar tree, or up to $20.00 at your local audio spot.

Good Luck

How will computers change our world in the future?

Well, computer hardware seems to leap every 2-3 years ...as it leaps onto something new the previous hardware becomes cheaper and more common this leads to a general advance for everyone within a few years. so as far as i can tell computers will become more advanced and the computers controling the world around us will change, more things will work faster and be automated using computerized A.I simple examples may be trafic lights or even robot hovers (around now ) .in general we will have slowly let machines and computers do all the work for us which means that people will have more time to themselves. perhaps computers will even start to go through their own evolution process.

What are some simple troubleshooting tips for a slow computer?

The answer depends -- I am guessing we are talking Windows PCs and if this is a NEW computer (less than 3 months old) I would have a complete virus and malware check done to make sure it hasn't become infected.

If, on the other hand, this is a recent system less than 1 year old - then defragmenting the hard drive; relocating the paging file to another hard drive; performing general housekeeping on the system should provide a noticeable performance increase.

If the system is older than 1 year and/or has less than 2GB of RAM; you might want to consider purchasing a newer systemor at least getting more memory -- PCs are getting better and cheaper all the time.

What are the types of LAN technologies?

Answer by Techsupport

There are different types of Media Access Control methods in a LAN, the prominent ones are mentioned below :

=> Ethernet - Ethernet is a 10Mbps LAN that uses the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol to control access network. When an endstation (network device) transmits data, every endstation on the LAN receives it. Each endstation checks the data packet to see whether the destination address matches its own address. If the addresses match, the endstation accepts and processes the packet. If they do not match, it disregards the packet. If two endstations transmit data simultaneously, a collision occurs and the result is a composite, garbled message. All endstations on the network, including the transmitting endstations, detect the collision and ignore the message. Each endstation that wants to transmit waits a random amount of time and then attempts to transmit again. This method is usually used for traditional Ethernet LAN.

=> Token Ring - This is a 4-Mbps or 16-Mbps token-passing method, operating in a ring topology. Devices on a Token Ring network get access to the media through token passing. Token and data pass to each station on the ring. The devices pass the token around the ring until one of the computer who wants to transmit data , takes the token and replaces it with a frame. Each device passes the frame to the next device, until the frame reaches its destination. As the frame passes to the intended recipient, the recipient sets certain bits in the frame to indicate that it received the frame. The original sender of the frame strips the frame data off the ring and issues a new token.

=> Fast Ethernet - This is an extension of 10Mbps Ethernet standard and supports speed upto 100Mbps. The access method used is CSMA/CD .For physical connections Star wiring topology is used. Fast Ethernet is becoming very popular as an upgradation from 10Mbps Ethernet LAN to Fast Ethernet LAN is quite easy.

=> FDDI (Fiber Distributed Data Interface) - FDDI provides data speed at 100Mbps which is faster than Token Ring and Ethernet LANs . FDDI comprise two independent, counter-rotating rings : a primary ring and a secondary ring. Data flows in opposite directions on the rings. The counter-rotating ring architecture prevents data loss in the event of a link failure, a node failure, or the failure of both the primary and secondary links between any two nodes. This technology is usually implemented for a backbone network.

Which is better laptop computer or desktop computer?

This section applies to most common RAM machine-based computers.

In most cases, computer instructions are simple: add one number to another, move some data from one location to another, send a message to some external device, etc. These instructions are read from the computer's memory and are generally carried out (executed) in the order they were given. However, there are usually specialized instructions to tell the computer to jump ahead or backwards to some other place in the program and to carry on executing from there. These are called "jump" instructions (or branches). Furthermore, jump instructions may be made to happen conditionally so that different sequences of instructions may be used depending on the result of some previous calculation or some external event. Many computers directly support subroutines by providing a type of jump that "remembers" the location it jumped from and another instruction to return to the instruction following that jump instruction.

Program execution might be likened to reading a book. While a person will normally read each word and line in sequence, they may at times jump back to an earlier place in the text or skip sections that are not of interest. Similarly, a computer may sometimes go back and repeat the instructions in some section of the program over and over again until some internal condition is met. This is called the flow of control within the program and it is what allows the computer to perform tasks repeatedly without human intervention.

Comparatively, a person using a pocket calculator can perform a basic arithmetic operation such as adding two numbers with just a few button presses. But to add together all of the numbers from 1 to 1,000 would take thousands of button presses and a lot of time, with a near certainty of making a mistake. On the other hand, a computer may be programmed to do this with just a few simple instructions. For example:

mov No. 0, sum ; set sum to 0 mov No. 1, num ; set num to 1 loop: add num, sum ; add num to sum add No. 1, num ; add 1 to num cmp num, #1000 ; compare num to 1000 ble loop ; if num <= 1000, go back to 'loop' halt ; end of program. stop running

Why does your computer turn off upon reboot?

There are many causes for this. The problems tend to fall in the below categories:

Hardware failure or other hardware problems

  • Failing power supply
  • Overheating CPU, bad CPU fan
  • BIOS selection switch in wrong position
  • Failing memory chips
  • Hard drive stalling or failing - If Windows cannot access certain files, it crashes.

Software and Operating system Issues

  • The operating system is incompatible with the computer, or OS bugs that manifest on certain hardware.
  • Driver problems, incompatible drivers
  • Certain CMOS settings were changed since the operating system was installed. Changing hard drive modes (AHCI, RAID, IDE) after installing Windows will cause Windows 7 to go into a reboot loop.
  • Software not compatible with the OS
  • Poorly written software
  • Certain malware or viruses
  • User is unfamiliar with the low power features.
  • An OS crash. If the blue screen stuff is disabled, the computer may simply reboot, and it may appear to be for no reason.
