A Comparison Of Software Engineering And Computer Science

Institutes of higher learning are still not in consensus of what is meant by many technical degrees, such as software engineering and computer science. These fields, along with information technology, information systems, and computer science engineering, are simply too new. Therefore, what one school or employer perceives as a requirement of computer science may be interpreted by another as software engineering.
There are many similarities between the two fields. Both will be expected to understand how computers work, how programs are structured, and what the user is entitled to expect. However, computer science is typically overseen by the mathematics department while software engineering is normally included in the engineering school.
In the early days, computers were hard-wired to perform a certain function. The user did little more than punch a button. Allowing greater user control led to the development of programming languages and compilers to translate "normal" language into computer language. Punched tapes or cards allowed the user to write his own routines. The actual keypunch was often performed by another, typically someone with clerical skills. A misplaced dot, missing bracket, or transposed letter meant that the entire program would fail. There was often no clue as to why, leaving the programmer to pore over the cards as well as his program.
Computer programming began to come into its own with the development of the personal computer. Simplified languages such as BASIC gave more control to the average user. A few minutes spent with a book enabled the user to begin to construct rudimentary programs. Many times, however, the lack of understanding about what a computer could and could not do led to failure. This laid the foundations for the software engineer, who not only understands the program but the physical abilities of the hardware.
One method of examining the differences between software engineering and computer science is to consider how most printers were controlled by the first personal computers. In most cases, changing printer functions such as font size, number of copies, or paper size required entering the proper printer string in DOS. Today, these functions are controlled from an interface on the desktop. The user may enter the information in the software or in the printer dialog box. In a simplified statement, one might say that the creation of the dialog boxes and underlying code was provided by a software engineer. The ability of the printer to understand the commands and comply with them was provided by the computer scientist.
In the most basic terms, CS focuses more on the hardware, circuitry, and networking involved. An SE is typically more concerned with creating a program that will be efficient in terms of size and speed and optimizing the user interface. Neither area, however, has a patent on any one area. To build a network or a computer that is reliable and efficient requires an understanding of what demands will be placed upon it. To write a powerful, "bug-free" program requires knowing how compilers operate, what the processor speeds mean, and the memory needed.
With little standardization between universities, the quality of the degree can vary greatly. Some colleges require CS majors to take Microsoft Office as their first programming course. In some cases, this may be followed by Pascal, COBOL, or RPG, none of which are in high demand today. They may also teach Visual Basic, Visual C++ or Visual J without first teaching the underlying language. By the same token, software engineers may be graduated without a basic understanding of wireless technology. Those seeking a degree as well as employers might be better served by ignoring the title and examining the actual courses required.
Not too many years ago, computer science positions were often filled by those with other degrees, such as electrical engineers. Software engineers were usually those with programming skills, many of whom held no degree at all but were self-taught. As technology became more complex, increased specialization followed. Only by considering the goal is it possible to differentiate between them. For example, if the goal is to produce the greatest game of all time, a software engineer is likely to be the one to meet the challenge. If the goal is to produce the next generation of gaming systems, however, a computer scientist is probably going to make the greatest contribution

Back to The Future - Meet Your Network Equipment Gear Demands

Network Communications are expanding rapidly, and this is changing the way we all work, live and entertain. We are now truly able to stay connected virtually anywhere and at anytime. The market and its associated technological advancements are moving quickly and companies need to stay ahead of the curve to be able to satisfy the demand for speed and data space.

In order to provide the ultra-fast data speeds necessary to stay ahead of users' rapidly growing online video demands and to set the foundation for a whole new way of networking, Cisco unveiled a new Internet technology that is simply futuristic. Known as "CRS-3,"  this new network routing system will be able to offer downloads of up to 322 Terabits per second, according to the company. To give an example, in Cisco terms, the router will be able to download the entire printed collection of the Library of Congress in 1 second and stream every movie ever created in less than 4 minutes.

Cisco said the CRS-3 will triple the speed of its predecessor, the CRS-1, and it will offer speeds of up to 12-times faster than the next fastest product on the market. The company invested $1.6 billion in the technology and will begin selling the routers at $90,000.

The foundation for the CRS-3 was based on rapid proliferation of smart-phones and the growing popularity of advanced applications that circle around how mobile providers will be responding to this change in service types and rising expectations of their users.

Additionally, the business and technical landscape is changing dramatically - expanding competition, shift in revenue streams, next gen. broadband technology deployments and move to all-IP architecture. These forces require mobile operators to build networks in new, "smarter" ways in order to be prepared to meet future demand.

Even though some say that the expansion of those speeds and network capacity are not necessary at the moment, many argued that the fast-growing media usage on mobile phones, mobile data and need for high-bandwidth mobile applications is exploding and will ultimately demand it.

The bottom line is that even if you do not require such a vast technological breakthrough at the moment, Cisco is definitely the company, one should look at, when considering what brand of networking to use. Satisfaction is guaranteed and you can be sure you are always staying ahead of the curve even with older models, since they are always designed and manufactured to meet prospective needs.

Digital Signage: Hybrid, Interactive Systems Amplify Marketing Impact

A new trend in digital signage is emerging that combines the strength of digital signs with the interactivity of digital kiosks. For many areas, such as retail shops, the sum of the two holds greater potential for marketers than either of the individual parts.
Known in some circles as hybrid digital signs and by others as interactive digital signage, these combo systems can capture the attention of those nearby by playing back compelling linear content -for example an enticing commercial or news feed- and immediately switching to an interactive mode when triggered by an external input, such as the touch of a viewer, the mere presence of a passerby or even environmental conditions.
Like a standalone digital sign, a hybrid system allows communicators to playback a pre-built sequence of elements, including video files, graphics, text, animation and live television. Those staples of digital signage are the makings of an effective message that entices interaction with the very flat panel on which the content plays.
Once viewers touch the panel or step within its proximity, the hybrid sign automatically interrupts linear content playback and displays a digital kiosk-like interface that lets a shopper touch hot spots on the screen, launching a pre-built interactive branching presentation. Navigating through the presentation, shoppers can find the information they want like product recommendations, pricing and availability.
Depending upon the level of sophistication needed, such hybrid interactive presentations can link to company's servers, pulling information needed for the presentation and collecting information about the consumer that can be stored on the server.
For instance, a hybrid system at an automotive retailer could send an inquiry to the store's server to access a database of recommended filters and oil viscosity specified by each car manufacturer. Matching information the customer entered about his car with the recommendations in the database, the system could check inventory for the right products, retrieve availability and pricing and present the information to the shopper standing at the hybrid sign.
Prior to offering that information, the system could ask the shopper to enter his name and address and to grant permission to be notified of future specials. With that data saved on the server, the retailer's marketing department can automatically send out coupons for oil and filters when next estimated time for an oil change rolls around.
What enticed the shopper to touch the screen in the first place? Perhaps it was a video playing back in linear digital signage mode of a favorite racecar driver discussing why it's important to stay current on oil changes.
On the front end of customer interaction, the hybrid system cast a wide net, cycling through a playlist of content designed to sell oil, followed by tires, then batteries, air filters -the list goes on an on. Each linear segment is backed up by an interactive kiosk component that's triggered when a shopper's curiosity is piqued by one of these linear presentations and touches the screen. On the back end, the system uses data that's collected to stay in touch with shoppers once they leave the store, offering special incentives to have them return. In essence, hybrid digital signage can help to extend the marketing reach of a retailer well beyond arm's length from the display panel and into the homes of shoppers who are willing to interact.
Interactivity doesn't haven't to begin with a human touch either. Imagine a hybrid digital signage system in a ski shop at the base of mountain. Skiers donning their boots and gloves might see a digital sign in passing as it plays back linear content; however, their attention might be focused when temperature, wind and solar sensors at the top of the mountain report conditions and trigger specific presentations. Lots of sun could call up reminders about needing sun screen. Heavy snow might trigger another presentation that makes them think twice about leaving the store before having the right gloves or goggles.
The possibilities for interactive, hybrid digital signage are only as limited as the imagination of creative marketers. To be sure, this aspect of the digital signage market is in its infancy. However, with the recent availability of the hardware and software needed to bring together the separate worlds of kiosks and digital signage, hybrid systems will certainly play an important roll in the unfolding digital signage market.

Wonders of Touch Screen Technology

Technology is progressing constantly and with this it is introducing new changes every day. In fact, it is technology that has largely made things easier for men. Touch screen technology is one of the wonders of the modern world that has now become a part of our life. There are different electronic devices that have this technology and they prove to be really very beneficial. Touch screen technology has been in the market for quite a few years now and its amazing wonders have really changed the lives of men. If you have not yet bought yourself a touch screen device, then it is high time that you go and get one.
The touch screen technology was originally developed mainly to be used in air traffic control and in nuclear power plants. However, with time, its uses have largely increased and now it has become one of the most important methods of spreading the use of digital media. The advent of this technology has greatly minimized the usage of the mouse and the keyboard. As a result, the people who lacked expertise in handling these devices can now use digital devices just by the touch of a finger.
This technology has been applied to various devices in the present world. Touch screen technology simply requires the touch of a finger to get a particular function done. The sensors are highly sensitive and there is not the need of even applying pressure. The surface is actually designed to be so flexible that it can easily recognize a contact on a particular part on the screen. On the basis of this recognition a function is actuated. This technology also functions at high speed and efficiency as a result of which the response time is extremely low. In fact, the device responds by performing the function immediately with the time difference being negligible. This in turn speeds up the flow of information. Any kind of information that is required immediately is processed within nanoseconds.
Touch screen technology also makes navigation very easy. Using this technology in a device like a cell phone does not require keys to begin a particular function. In most cases, you would be given a special pen which you require to touch the screen with to operate the phone. At times, fingers can also replace the function of that pen. Thus this is highly a user-friendly facility that is present in most of the latest devices of today.
The touch screen technology is largely used in many different fields, right from the big industrial houses to banks and other organizations. It is very practical in nature and even an ordinary individual can make use of this technology by owning a cell phone. Many people are taking full advantage of this technology in their everyday life. The future will certainly see the application of the touch screen technology on a much larger scale. We are likely to see a number of wonders of this technology in the coming years.
