Wireless Microphone System And Multimedia

techno13

Wireless microphones are one of the essential devices used in computers, developed primarily for multimedia tasking. This system simplifies the work in an efficient and expedient manner. These are effective and versatile tools used in varied applications speech recognition and dictation, video conferencing, concerts, computer telephony, and more.

Description of Wireless Microphones
A computer wireless microphone is a microphone with no tangible cable and is directly connected to the sound recording (sound card) of a computer. Its hands-free feature allows for multitasking.

The wireless microphone technology is now being incorporated in technologies like the mouse, speaker, printer, scanner, and digital cameras. Audio applications include speech recognition, speech dictation, computer telephony, video conferencing, and internet telephones.

The sound card is typically included as package on personal computers and is attached to the motherboard of the PC. It is usually coupled with built-in microphone and line level ports that work in the analog audio signal input and output of the audio data.

One advantage of the wireless microphone system is being able to customize a loud speaker for various modes like speakerphone mode or non-speaker audio mode. These microphones are often joined to the head set and permit you to have the benefit of better quality of music and sounds. The head set microphones also let you move freely in all directions without the risks of possible stumbles or trips.

Nowadays, there are different standards, frequencies, and transmissions of modern devices being used to replace the conventional microphones cable connection and turn it into wireless. Wireless microphone can be transmitted in radio waves using UHF or VHF frequencies, AM or FM frequencies or any other digital software scheme. Low cost microphone models make use of an infrared light. To avoid interference, most advanced variations of this device operate selected frequency to facilitate the adoption of several computer programs simultaneously.

The Modern models of computer wireless microphone transmit clear reception. The two separate receiver modules with antennae reduce dead spot in sound waves.

Two Types of Most Frequently Used Digital Transmission Scheme
The Digital Hybrid System uses an FM analog audio signal to combine with Digital Signal Processing (DSP). It enhances the audio spectrum to make it easier to get the right frequency. DSP reduces noise and eliminates undesirable effects. This wireless microphone operates on a high level bandwidth of 200 to 500 kHz.

On the other hand, the Pure Digital System is a frequency-hopping spread technology. It requires more bandwidth than an FM signal and operates at 900 MHz or 2.4 GHz bandwidth.

Where to Use the Computer Wireless Microphone System
Computer Wireless Microphone System is substantially versatile. It can be applied in vehicles associated with cellular phones, transportable video cameras, and other multimedia device. In addition, these device systems can be use in concert halls, live stages, radio stations, or wayside recording. These wireless microphones can function well in other two-way communication devices such as aircraft headsets.

Computer Forensics Chain Of Custody

techno14

As the trend for high-specification mobile phones and computers continues at a rapid pace so too does the potential for electronic media misuse and abuse. This kind of fraudulent activity is becoming more commonly seen in legal cases, particularly with employment tribunals. Legal firms are beginning to employ the services of computer forensics experts more widely in documenting electronic evidence and providing litigation support, as this can be crucial in the outcome of cases.

Computer forensics can be used to track and provide evidence in cases of intellectual property theft, money laundering, hacking, moonlighting and the accessing of illegal or inappropriate websites. Digital forensics can also help to secure concrete evidence of illegal activity not usually associated with electronic devices including blackmail, drug dealings and abusive behaviour.

Regardless of whether digital forensics is being used in a criminal case or a civil matter (even as part of an E-discovery exercise), maintaining chain of custody is vital. This is the fully documented tracking of evidence for the period of time that the forensics team has possession of an electronic device. It ensures that each member of the team can be held accountable for any action that they take with the media.

The purpose of this chain is to log the movements of the data, how it has been stored and subsequently analysed. It is essential that this documentation presents an accurate description of any copying, transportation and storage that has occurred, to prevent any potential legal challenge.

It is worth pointing out the differences between e-discovery and computer forensics. E-discovery is the method of processing and manipulating electronically stored information to be used in legal cases. This can take the form of emails, word processed documents, images and any other type of file, which can be filtered, viewed, analysed and categorised effectively via this system. E-discovery using a forensically acquired data set is crucial in maintaining the integrity of any information present, while potentially recovering any deleted material that may be appropriate for the legal proceedings.

Computer forensics is a highly complex industry that requires the latest in product knowledge and technical expertise. Specialists will have years of experience in the on-site capturing of data from computers, servers and other forms of electronic media. This data is then analysed by their forensic analysis specialists, and used to track how a particular device has been used. All areas of the chain of custody documentation will be completed to the highest standard to ensure peace of mind for the client.

Computer Safety Rules

techno17

Do computers interest you? Have you ever just had the urge to open one’s case and mess around with it? This is natural as they are very intriguing machines, and they are all around us. Sometimes it is hard to get through a full day without using a computer at some point in the day. But if you are dealing with computer hardware, precaution is necessary in
order to keep yourself and your computer’s components safe. There are some procedures that are recommended when removing and installing parts. Just like any other machine, there are always dangers when working with one. Here is a list of some computer safety rules to keep in mind.

1) Wear an anti-static wrist strap when handling a computer’s internal parts. Snap it around your wrist and connect the clip to a metal area of the computer case. This grounds you so that harmful electricity will not transfer between your hand and the parts you touch. Even fairly small amounts of electricity can cause costly damages to your machine.

2)Turn off and unplug the computer before working on it. This may be obvious to some, however, it is very important. Not only could you damage the components, but you could also injure yourself. So turn it off, unplug it, and then push the on button to allow any stored electricity to dissipate.

3)Use anti-static mats. Anti-static mats help prevent electrical current transfer from the floor(or other surface) to the computer. This is especially important if your computer is on a carpet. So just put the anti-static mat on the surface you are going to work on your computer and place the computer on top.

4) Clean your computer on a regular basis. Dust builds up on computer hardware and can cause the components to retain heat while they run. Over time, this can overheat the parts and cause them to malfunction or breakdown altogether. So it would be wise to dust your computer’s interior on a regular basis, being careful not to get any liquid on or touch any internal components too much. Just remember, if you are vacuuming out your computer, do not use any vacuum that would create an electrostatic charge, as this could damage the components. There are tool made specifically for cleaning electronics.

5) Also, make sure you never take power supplies apart. You really do not want to deal with them as they are the most dangerous part in your system. This list can and should be added to. Though it is a good start, in no way is it all-inclusive. You can never be too cautious when working with electronics. And unless you are an experienced user, you may want to hire a professional to install and maintain your computer’s components. But if you do decide to work on your computer, make sure to always be
cautious and safe. The potential of hurting yourself or damaging your computer is just not worth being lackadaisical about safety.

The Four Main Causes Of A Slow Computer

techno

When someone buys a new computer or reimages a hard drive, one thing that usually impresses them is the speed of their system. The computer wakes up quickly, and Web pages display almost instantly. Over time, though, computers often slow down. Here are the four main reasons why:

Too many programs: It’s not unusual for a person to have dozens of programs installed on their computer. While many people think they only consume system resources while they are actually running, this isn’t the case. Every program takes up some of the computer’s memory. If your computer takes forever to start up and runs slowly, you may simply have too many programs installed.

Not enough memory: RAM, or random access memory, is what allows the computer to perform tasks like opening documents, accessing Web pages, and loading programs. All programs consume RAM, and if you run out, your computer will be extremely sluggish.

Malware: This is a broad term used to describe viruses, spyware, and adware. All types of malware can slow down your computer, and it’s a very common reason why computers don’t perform like they did when they were new.

Registry errors: Your computer executes tasks by accessing files stored in the Windows registry. Over time, these files can get moved or split apart. Your computer still needs them, though, and takes longer to find them. This has the effect of slowing down your entire system.

The good news is that these problems can be fixed relatively easily. Deleting programs you don’t use, running a registry repair program, and investing in quality anti-virus and anti-spyware software are all ways to speed up your system. If your computer is very old, it may simply not have the RAM to handle everything, so you might need to upgrade your desktop or add some memory to increase speed.
