Micromachining

Image
 There are a lot of different technologies that are being continually used today which in tandem ensure that you are able to get things done and not have any problems in figuring things out. There are concepts out there that you might not even be familiar with, but might have made use of unknowingly. It is all these small things that ensure that we are able to live heartily and not worry about small problems that might be irksome. Micromachining is one such technology, thanks to which a lot of things are now possible. Intricate medical equipment The field of medicine is an effervescent one, with changes happening round the clock. Hence, there is a constant need to improve machinery and tools to enable physicians and surgeons to do a better job. There are so many different forms of micromachines at work today that enable doctors to precisely diagnose and treat complex conditions. Hence, Micromachining is making it possible to enable doctors to find and treat conditions with ease th

Internet Security For Children

Image
 It seems that most children in today's world are using computers and laptops and the trend should only continue as computers become more reasonably priced and increasingly important in our society . As a father to three great kids, one of my biggest concerns is the safety of my children while surfing on the Internet . Because of generous relatives, each of my three kids has their own laptop and because they received them as gifts, it would be difficult for me to take them away from them. (Thanks for checking with me, relatives!) So, the laptops appear to be here to stay. My major concern is how do I provide security for my children on the Internet? Because it would be literally impossible for my wife and I to physically watch our children while they are on the Internet, there had to be a means by which they could be observed on the Internet without it being too obvious but yet powerful enough to keep them out of harm's way. So, I took on the mission to find a service that c

Image
 Media Center Remote Control is specially designed for windows media center and the windows 7 operating system, the latest in media center remote controls now offers flexible operations with most functions being activated by voice or buttons. This remote is enabled with speech recognition technology. Speech Recognition Technology also known as automatic speech recognition or computer speech recognition, converts spoken words to text. With voice controlled remote, there are multiple speaker profiles selectable by voice for example say the command: 'this is Smith' and Smiths profile will load automatically. Advanced position sensing software will also isolate the voice of the speaker and ignore any concurrent conversations in the background. Why use a Media Center Remote Control? We can use this remote for a number of reasons, among which some of them are as follows: • Watch, record, control TV with the tuner. • Control, play and rip music. • Create, play and control slide s

Advantages of Digital Systems

Image
 1) The devices used in digital circuits generally operate in one of the two unites, known as ON and OFF resulting in a very simple operation. 2) There are only a few basic operations in digital circuits which are very easy to understand. 3) Digital techniques require Boolean algebra which is very simple and can easily be learnt. 4) Digital circuits require basic concepts of electric network analysis which can easily be learnt. The principal electrical char¬acteristics required are switching speed and loading considerations. On the other hand, analog circuits and systems involve frequency and time domain concepts, complicated circuit analysis techniques, etc. which make the un¬derstanding of these circuits much more difficult than the digital circuits. 5) A large number of IC's are available for performing various operations. These are highly reliable, accurate, and small in size and the speed of operation is very high. A numbers of programmable IC's are also available.

Data Security Over Computer Networks

Image
 When designing a network, data security must be included in the design plan because protecting data while it is transmitted is very important especially if is is sensitive data. Additionally, authenticating users when trying to open protexted pages is also very important to avoid storing data. Finally receiver must assure that the data is received as transmitted. The previous points are explained below separately . When transmitting data across a network, many attackers exist that can intercept the data and read it. The data are transmitted in the form of binary signals. Any one having a detector can read this pulses on the line. The data transmitted can be very sensitive especially in military applications. The solution to the above problem is to scramble the data before transmitting them according to some rules. On the receiver, these rules must be known in order to extract the original data from the scrambled data. This process of scrambling is called encryption. Encrypting d

Ergonomics and Computers

Image
 Its amazing how many people use computers in the wrong way. Simple things like having your monitor sitting at the right height play a huge role in how comfortable you are, especially over the long period. For example, your monitor should sit with the top of the monitor at about eye level. Any lower or higher and you risk doing damage to your neck. So many people have the monitors lower, but if you think about when you stand normally the most comfortable position to look is straight forward, not bent down like that would promote. Having the right height desk, chairs and back rest are also very important. Generally though I have found that it is your wrists and fingers that suffer first, before your back. To counter this, you need to ensure that you are working ergonomically. Get a mouse pad that is customized in a way that is comfortable. Your wrist pads should support not only the wrist and arm, but also the side of your hand that rests all of the time . A good quality pad will ma

Computer Using Behavior

Image
 Computer users, roughly speaking, fall into one of several categories. Here is a brief summation. Extreme Users: Extreme users spend nearly every waking moment in front of a computer and do so voluntarily. These folks are definitely techno enthusiasts. They tend to be attracted to such things as web design, gaming, programming, computer graphics , etc. They use the computer as a tool and as a form of recreation. Their lives are intertwined with the internet. These are people who would be lost without a computer. They always want to have the latest and fastest computer and are willing to pay top-dollar for it. Heavy Users: Heavy computer users are folks who tend typically use computers for a work-related purpose. This alone consigns them to life in front of a computer screen . They spend around a 3rd of their lives in front of a computer. They tend to become adept at using various applications. They tend to develop decent typing skills out of sheer repetition. Heavy computer users ar

Current Technology

Image
 The technology and its enhancement each day has become the driving force of change in the modern world. It has altered the economic structures as well as the way we communicate . Voice Over Internet Protocol (VOIP) is one of the general terms these days as concerned to transmission technologies for the delivery of voice communications over IP networks such as Packet Switched networks or Internet. It is a system that allows you to make voice calls using a broadband connection instead of regular phone lines. IP Telephony refers to communication that is transmitted via the internet. Under this system communications are converted into digital signals that travel over internet. All that you need to make your IP calls is a broadband connection service such as DSL or LAN network and a computer if the devices are such. Because of its bandwidth efficiency and cheaper rates that is provided with VOIP technology it has been becoming more and more popular. More and more VOIP service provid

Wireless Camera

Image
 With the innovations in technology today it is certainly raising the standards we are becoming so accustomed to. Everyone knows that wireless technology took off about 10 years ago and has made an impact on all our lives. A lot of the things that we take for granted are now available free from wires, the freedom of the cordless phone, headsets that allow us to get up and stretch our legs whilst still being able to see the computer screen even simple things like the wireless mouse. In a world where security is becoming a bigger issue for all of us it is no wonder that cameras have now embraced wireless innovation . Its not that long ago that it was all very James Bond and the movies were the only place you might see this. So many people from the ordinary man on the street right up to high powered leaders and the corporate world are now all being very security conscious its no wonder that these types of camera are becoming more and more popular. They work with relatively simple techno

Technology Boosts Solar Efficiency

Image
 The solar battery is a device that converts luminous energy to electrical energy through photoelectric effect or chemical effect, and at the present stage, the diaphragm type based on photoelectric effect is leading the way of solar battery. At present, many countries have been developing a mid-and-long term plan for solar energy exploitation, preparing a large scale on the solar development in the 21th century. The applications of the solar battery have extended from military and aerospace fields into fields of industry, business, farming, communication , domestic appliance and public facilities fields. In a long term, with the improvement of the skills for manufacturing and the invention of new conversion devices, and the huge demands of environment protection and the renewable sources of energy by many countries. The solar battery is still an effective way of making using of the solar energy, thus paving the way for people to using the energy on a large skill . In recent years,

Computer Related Needs

 As young professionals , we have a lot of things that we do on a regular basis. We venture into different activities: from going to countless meetings to power lunches to making reports to taking calls from different clients. All these are dependent on what our job entails. But one thing is for sure: we all use our computers for different job tasks. Be it our desktop or laptop, we are extremely reliable to our computers for both personal and professional needs. I personally use it for making reports for work, chatting with friends, downloading music , updating my social networking files, doing research and a whole slew of other things that I can only do online with the use of my computer. So I see to it that my personal computer is well taken care of and that if it needs repair, I go to the nearest computer repair charlotte in our area. So if you live in the area of Charlotte North Carolina , you better be comforted with the fact that there is a shop that will help you with all your

Electrical Components

Image
  Electricity is an essential requirement for human beings, so it is important to know the names and functions of electrical components that are around you. I would like to introduce to you some electrical components, namely: #1. Resistor Resistors are electronic components that have a function to provide resistance against the flow of electricity that flows into an electrical device. In the electrical circuit required resistor with certain specifications, such as major barriers, the maximum current and the characteristics of temperature and heat resistance. Resistors provide resistance for electrical components have the appropriate electrical current flow (not great). In addition, the resistor can serve as a voltage divider. #2. Capacitor Capacitors are used to store electrical charges. One type of capacitor is the parallel chip capacitors. This capacitor consists of parallel metal pieces separated by an insulator called a dielectric. When the capacitor is connected to a battery

Computer Time Synchronisation - The Basics

Image
 With so much automated in the modern world and with computer networks running everything from finance to health services, keeping, storing and transferring information needs to be secure, accurate and reliable. The time is crucial for computer systems to ensure this. Timestamps are the only information computers have to assess if a task has been completed, is due, or that information has been successfully received, sent or stored. One of the most common causes of computer errors comes from inadequate synchronisation of timings. All computer networks need to be synchronised , and not just all the devices on a network, either. With so much global communication these days, all computer networks across the globe need to be synchronised together, otherwise when they communicate errors may occur, data can get lost, and it can pave the way for security problems as time discrepancies can be used by malicious users and software. But how do computers synchronise together? Well, it is made

PC Software

 Usually, the case could have been to report the criminal offense to the police and begin over using a brand new laptop. But this gentleman's case will end up to become one of a kind. With patience, perseverance , and a proper option made before the laptop was stolen, he got it back. That option was to make use of technological innovation called remote PC Access Software. He used the knowledge inputted by the laptop thief the fact that the laptop proprietor acquired using only this software, and he was able to follow the criminal and get back which sort was rightfully his with the help of the city police. Most businesses use one or two form of loss prevention, or LP, team to run a mixture of multiple tasks. In retail stores, these groups or departments usually concentrate on catching shoplifters or employee's stealing merchandise or time from the store. In much more skilled workplaces or workplace buildings, LP teams work differently all together. There was a time that su

What Is Cache Memory?

Image
 We saw that the use of main memory helps in minimizing the disk-processor speed mismatch to a large extent because the rate of data fetching by the CPU from the memory is about 100 times faster than that from a high-speed secondary storage like disk. However, even with the use of main memory, the memory-processor speed mismatch becomes a bottleneck in the speed with which the CPU can process instructions because there is 1 to 10 speed mismatch between the processor and the memory. That is, the rate at which data can be fetched from memory is about 10 times slower than the rate at which CPU can process data. Hence, in many situations, the performance of processors gets limited due to the slow speed of memory. Obviously, the overall performance of a processor can be greatly improved by minimizing the memory-processor speed mismatch. A primary storage or memory of a computer system is made up of several small storage areas, called locations or cells. Each of these locations can st

Digital Camera

Image
 Digital cameras are designed to be familiar to anyone who has ever used a film camera. But they have many extra helpful features too... Most digital cameras have similar basic features found on the side, the front, the top, and the back. In this article will introduce you to the side and the front typical features of a compact digital camera, and will go on to discuss more specialised functions later in the article. Is important to check the manual supplied with your camera to see which additional features your camera has. The Front Features 1: Camera Auto Focus (AF) Sensor Special sensors help to focus automatically. Some cameras 'sense' changes in contrast, while others use a beam of infra-red (IR) light, particularly in low light. Higher specification cameras sometimes use a combination of both systems and might have Face Priority AF where the camera can 'See' a face and focus only on that. 2: Camera Lens Most digital cameras come equipped with a zoom lens th

How Computer Viruses Work

Image
 Virus is a small computer program that is designed to give someone control over your computer. Viruses usually attach itself to other programs. For example if the program is infected with the virus and you run it. It most likely will reproduce itself to other programs or make your system unstable. Viruses can be distributed by emails as attachment. Once you click on the email it will infect your computer and send itself out to all your contacts in email address book. A worm is a special software that scans computer networks for specific security holes. Once if finds them it infects computer and replicates itself. Trojan horses are computer programs that pretend to be something else. For example you click on mp3 song but instead of listening to the song your computer crashes . Spyware is similar to malware it a small software designed to collect user data without him / her knowing it. Malware short for malicious software . Malware is a any type of software that is designed to work

The World's Fastest Microprocessor

Image
 IBM claims that they have developed that fastest processor with 5.2 GHz speed. Here you do not even have to use nitrogen to cool off the processor. No more, you have 1.4 GHz processor that claimed to be the fastest processor and this has been ages ago. Now you have all new IBM 5.2 GHz z196 that is designed to be the fastest in today's time. This is a four-core slab. It has been manufactured using 45 nanometer technology and this is the reason for boasting 1.4 billion transistors. It has the ability to handle more than 50 million instructions every one second. IBM 5.2 GHZ z196 Details IBM z196 has the facilities for symmetric multi processing. The specific design for z series has helped processor to share cache across two SC ships. This IBM processor is fastest and it can easily handle good number of transaction details. This is z196 processor that makes use of four core chip. It contains around 1.4 billion transistors. IBM engineers designed this in New York and it was manufa

My Computer Keeps Freezing

Image
 By now, you are probably tired of hearing, " Help me ! My computer keeps freezing!" whether it is coming from your kid, your husband, or from inside your own head. Sometimes you just want to yell, "Slow computer , fix yourself!" Stop yelling. The older a computer gets, the more you will start to notice it takes longer to boot up, and maintenance it is probably going to need. Over time , computers pile up information, programs, and plain inefficiency. By default, many programs try to tell you they need to start every time Windows starts. Sometimes they do not even tell you and just go ahead and do it anyway. Other programs ask politely if you would like them to start when Windows starts. This is all fine and dandy until you have so many programs starting at the same time your computer keeps freezing . If you share a computer with the rest of your family , you might not know everything that is being installed. It could be hard to keep track of how often and how ma

How to Make Beats

 Maybe you're a rapper who is tired of wack producers approaching you with their wack beats. Maybe you've already dabbled in beat making but you're trying to brush up and learn more about the craft. Or maybe you are just a plain old music enthusiast who wants to take their passion for music to the next level and create your own. Whatever your reason, you've come to the right place. Obviously this article can't teach you everything you need to know. There are entire books and even entire college curriculums dedicated to giving you a proper music production education . However this article will hopefully give you a start, and you'll be able to research more using what you learn here. The first thing that you'll need is a method for creating beats. There are a number of different solutions here. If you are really only trying to be a mild hobbyist there are a bunch of online beat making programs that you can gain access to for around $30 to $40. These include

Dropbox - The Free Online Storage Service

Image
 Dropbox is a free online storage service and much more. It a allows you to share files with others easily. It also, allows you to sync files on all the computers you use (home, work, laptop , etc). In reviewing this product I used its free service which allows you 2GB of free online storage space. First, let me give you some details of how dropbox works. You download the dropbox software on all of the computers that you want to share information on. This adds a dropbox folder to your computer and anytime you save anything to the dropbox folder it automatically updates that files and folders across all of the computers you have downloaded the dropbox software on. Dropbox also allows you to share files with others. The way this works is you right click on the file you want to share and then it ask you to put in an email address for the person you want to share the file with. Once you put in their email it sends them an invitation telling them that you want to share a file and tells
