The Personalty of Computer Technology on Our Familiar Lives

 

These days, the computer technology industry is rapidly growing and changing. Along with that growth and change of computer technology are the people who almost instantly adapt to the changes.

Computer technology has made our lives a lot easier and convenient. For instance our banking needs. Years ago, people had to manually file the important data of their customers; now they just use the computer to find these data. In just one click, they would instantly find the name of the customer, the birth date, the address, e-mail address, phone numbers and etcetera. As for the clients of these banks, they can also easily get a quick look at their account balances through logging in to the bank website; in addition to that a lot of people are able to apply for a loan with the use of the computer.

Because of the birth of computer technology, we now have credit cards or what others call plastic money, which are very useful especially when we do not have cash on hand or when you are ordering a certain product through the internet. It's amazing how computer technology has changed so much our way of living. Nowadays, purchasing products such as cellular phones, bags, household utensils, and clothes or even paying the bills can be effortlessly done at the comfort of your own home.

With the use of the computer a lot of students especially those with unfortunate disabilities or severe illnesses are able to enroll to different schools through home schooling. Students are even able to take their examination tests or check out their grades by the use of the computer.

As far I know computer technology has helped a lot of businesses to better serve the community. But the computers have not only helped us in the business industry; it also has an effect on our communication systems. Long before the computers were born, writing letters were the main source of communication, which would be such a hassle most especially to those people who lived in far away places; plus telephones were quite expensive so people would pretty much prefer writing to their loved ones. And for that reason, people who are far away from civilization would really have a hard time communicating with others.

Now, we have e-mails, and live chat, or even voicemails. We now already have video calling in which we would be able to see the person that we are talking to. This would be really great for people who have loved ones that are away from home. Getting in touch with one another is now a piece of cake.
Computer technology has changed our lives for the better. Without it, we would still be living in the pre historic times.

Lets Know of Computer Technology - Is it Good Or Bad?

The 21st century has been the age of so many technological breakthroughs and advances, technologies aimed for one purpose and that is to make the lives of people better by helping them become more efficient in their work. One such technological breakthrough is computer technology.

Computer technology has grown in great proportions starting from a computer with a size that of a room to a small well-designed palm top computer. Computers nowadays have become an indispensable part of the lives of people, especially at work, at companies, businesses, schools, offices and even in homes.

It has made the world smaller, but has it made our world better? It would then lead us to ask whether computer technology is good or bad. Now let us try to look at first some of the bad effects. With the advent of computers and with the internet it has become easy to access pornographic sites, children are more exposed to explicit content; some students would lose focus on their studies as they play computer games. The number of obesity cases has increased and it has been attributed to too much computer activity that led to less physical activity among a number of people.

On the other side of the coin, computers have opened a whole new world of possibilities. It is now easier to gain information on world events; you can even find a job in the internet; you can spread advocacies to a vast number of people all over the world; and most importantly it is now easier to be connected with one another even if you are on the other side of the globe.

Computer technology, just like any other material on earth has been created with a common good in mind. Just like a knife, it has been made to cut and slice food to speed up cooking time for people but it can also be used to kill people, and you cannot ban the use of knives in order to stop killing. And so you can't blame computers for the problems it may have caused for it is the people who use them who caused the problem. It has disadvantages and advantages that must be taken into consideration.

But the problem is not computer technology itself; the problem resides on the people who use it. Computer technology is generally good for it can bring in a lot of good if it is used properly, but can do great harm if used unwisely.

People have choices on how they make use of earth's resources, and that choice will determine how certain materials will affect people, be it good or bad.

All About the Proxy Technologies

There are lots of misinformation surrounding internet proxies and it isn't surprising when one or the other type of proxies crop up when users are told to select the best. One of the worrying aspects of this is that proxies have become synonymous with security.
Though proxies make an individual secure, they also help achieve the opposite. They are always an intermediary which sits Proxy is always an intermediary. It is a server which sits between the sites the user visits and the user. This is wonderful if you want to bypass some restriction or surf anonymously. However, you are trusting and sending all data to the proxy server owner.

Features
If you are using proxy server - either web based, or surfing from school or work - each request from web page first goes to the proxy. The server then examines the packet content and header, checking with its internal rules.
For instance, anonymous proxy servers reconstruct data packet with a varying IP address. Thereafter, the proxy server sends request to target web server, receiving the reply later. Thereafter, it is forwarded back to the initial client.
The reasons for using proxies are many. However, the fact that all data is directed through them mustn't be forgotten. Proxy server is usually enforced in work or school for ensuring that nobody breaks the policy of internet usage and prevent people from inappropriate content access.

Overview
Few people set up storing proxy servers, available purely for speed to save web sites accessed frequently. Transparent proxies don't modify any such requests, and therefore, don't hide the IP address. Hostile proxies steal passwords and information.

Though these are some of them, the uses are varied. Remember - whichever proxy you use - whether it is the one page internet web proxy surrounded by ads, or sophisticated proxy caching at work - the proxy administrator has full control of the data. Hence, it is important to take care.
The best proxy is the one which is securely run by someone trustworthy who deletes and secures the data.

Dish TV Programming Channels from MPEG 4 Technology

Dish TV programming channels are aired on MPEG 4 Format. Because of this viewers of satellite televisions are getting distortion free images on their television screens. The programs are broadcasted straight away from the geosynchronous satellites directly to the viewer. This is yet another reason that has made satellite television quite popular among people.
About MPEG 4

MPEG 4 is a patented technology that was introduced at the end of the year 1998 and it soon gained immense popularity. This format is used mainly to stream internet media and later on it was introduced for streaming television signals. Today MPEG 4 is recognized as a standard video and audio coding format. MPEG 4 is quite similar to MPEG 1 and MPEG 2 since it shares several features from these two formats. New features have been added later on for make it capable for 3D rendering. The well known codecs such as DivX, Xvid and Nero Digital have now become a part of this amazing compression format.

Previously this audio video compression format was aimed mainly at low bit-rate video communication. But soon the scope of this compression technology got expanded and now it has become the primary tool for multimedia coding. This format is extremely efficient across a wide spectrum of bit-rates, which is from few Kbps up to tens of megabytes per second (Mbps). MPEG 4 is known for enhancing the efficiency of coding and it is even capable of encoding mixed media data such as audio, video and speech.

Since this amazing audio and video compression format is used for streaming television signals, therefore dish TV service providers have decided to adopt this technology to offer maximum TV viewing pleasure. For this purpose the service providers of satellite television have introduced newer receiver models that are compatible with this format. One such receiver model is ViP 622 HDTV DVR receiver.

About ViP 622 HDTV DVR receiver

This is a unique satellite TV receiver that supports both MPEG 2 and MPEG 4 technology. This is a High Definition Receiver that has two tuners named TV1 and TV2. it has a built-in 120 gigabyte hard drive that is capable of storing 100 hours of television program recording. This device allows you to operate it in two modes. One is the Single Mode and the other one is Dual Mode. In single mode you can operate its two HD tuners from a single remote and in dual mode, you can record a TV show while watching another channel.

4G Technologies to Affect Mobile VoIP Adoption

As VoIP traverses the path to mainstream, new developments in Internet technology continue to impact the growth of broadband telephony. One such new technology that is expected to sustain, if not help, VoIP to gain a wider acceptance is the fourth generation (4G) in cellular wireless technology, which succeeds the 3G systems currently in use. The competing 4G technologies are expected to provide secure broadband connectivity with giga-bit speeds that are perfect for demanding applications that require high-bandwidth and top-speeds, such as online gaming, multimedia streaming and IP-telephony.

Some mobile carriers have rolled out the infrastructure and equipment necessary to deploy the new technology, such as the 4G system implemented by TeliaSonera in Stockholm and Oslo in Scandinavia. Moreover, the market release of the first ever 4G mobile phone - the HTC EVO 4G - this year signals the beginning of a new era in mobile connectivity.

Competing 4G technologies

The most striking aspects that define 4G technology are the high-throughput requirement (up to 1 Gbit/s); the ditching of the CDMA radio technology used in 3G systems in favor of multi-carrier transmission using frequency-domain equalization schemes; and the use of multiple intelligent antennas for transceivers. Although there are quite a number of implementations proposed for 4G, two candidates have so far succeeded in attracting the most number of investors and adherents: WiMax and LTE.

WiMax stands for Worldwide Interoperability for Microwave Access, a telecommunications protocol that delivers 'last-mile' wireless broadband access. The current version of WiMax (802.16e) offers up to 40 Mbit/s, still way below the 4G standard, but the imminent IEEE 802.16m revision is expected to ramp up the speed to up to 1 Gbit/s for fixed connections.

LTE stands for Long Term Evolution, a standard that improves on the Universal Mobile Telecommunications System (UMTS) that was part of the 2008 revision of the 3G systems. The first release of LTE also falls short of the 4G standard on throughput - and for this reason the release was called 3.9G. The two largest mobile carriers in the US - Verizon Wireless and AT&T Mobility- have announced that they will convert their existing systems into LTE beginning 2011.

VoIP and 4G

One or both of the competing 4G protocols are expected to provide all-IP networks with high-bandwidth and low-latency. The 4G standards are expected to integrate voice services on top of the data stream, to give voice calls made via cellular or VoIP connections unmatched clarity and quality.
WiMax is a form of wireless Ethernet like WiFi, but the former offers more in terms of reach (WiMax signals can cover several kilometres), sustained throughput and quality of service. However, Wimax runs on the licensed radio spectrum unlike WiFi which is on the unlicensed and unregulated bands. LTE, on the other hand, is more similar to mobile cellular systems but it does offer mobile broadband capability that is useful for packet transmissions.

Both these technologies would be great for mobile VoIP calls, although it remains to be seen if the cost per call in either system will be reasonable compared to current costs of cellular calls.

Saiju George is an IP Communications and business software expert. He enjoys promoting great mobile VoIP applications that integrate well with hosted VoIP pbx solutions.
