Cheap RAM

The cheapest type of RAM is dynamic RAM because it uses traditional technology as opposed to static RAM, which is expensive and uses advanced methods to store and retrieve temporary information. Dynamic RAM has capacitors that act like vessels that store temporary information for the CPU to use as and when required. This makes them cheaper as compared to static RAM that is expensive because it does not use the same technology as a dynamic RAM.

RAM chips are available in the market within a price range of $4 to $400, depending on its make, brand, upgrade, and type. The modern computer usually uses dynamic RAM that is at least 128 MB in size. This RAM race started in the 1990s when 2MB of RAM were used. However, technology has improved in leaps and bounds since then, and today using less than 128 RAM would be not advisable, as the speed and efficiency of the computer will be dramatically affected.

SIMM RAM is the oldest and cheapest of them all but can only be used with old machines and is not compatible with newer ones. It is available for less as $5 and can be bought on the Internet. A memory upgrade is the most cost effective method of improving a PC’s performance, and memory upgrades are very simple to install and require no configuring at all.

A 4 MB 30pin 60ns 3-chip SIMM RAM with a tin lead and a 2-piece 2 MB x 8 chip and logic parity is priced at $7 to $8, whereas a Cisco 16 MB Catalyst 8000 Flash SIMM can cost up to $89. The price of a RAM chip depends upon the number of nanoseconds, the brand, type, megabytes, and other such factors. The price of RAM also depends upon the type of computer that a person uses. This is because an older computer will usually use a 2 to 8 MB RAM, but a newly bought computer will need a 128 MB RAM in order to function efficiently.

Broadband Internet Access

Broadband Internet access has redefined the boundaries of web networking. The time required to access the Internet, as well as to download information of different frequencies from the web, has been dramatically reduced. Web information is conveniently and easily accessible without being affected by long distances. Broadband Internet access is especially suitable for those who require instant and prolonged or constant (24/7) access to the Internet. Although it is a little more expensive then the traditional narrow-band Internet connection or dial-up network, the benefits fully compensate for the little price difference. A broadband connection ensures that the functioning of the cable and television line is not affected during connection, and vice-versa.

There are different types of broadband Internet access. The most efficient and reliable way it is accessed by home customers is through a cable broadband connection. This runs on an existing cable or coaxial connection. Another convenient way to access this technology is a DSL connection that uses an existing telephone line. Both these technologies are widely used by urbanites already having a telephone or cable connection. Most subscribers provide a 24-hour service for a flat monthly price. The T1 and T3 type of broadband connection is generally accessed by large business houses and universities. These oldest forms of broadband connections are the most efficient, but are also the most expensive. Access to broadband Internet connections is dependent on one’s geographical location. Although distance doesn’t usually affect speed and efficiency, the availability of infrastructure is a problem in remote rural areas and while one is traveling. Many of these difficulties have been addressed by the advent of satellite broadband Internet connections using land stations to receive land station transmissions. Wi-fi, or wireless broadband connection, is a revolutionary technology that promises to remove the restraints of distance, time and location. It allows one to access the net even in mid-air. Technology and special programs have made broadband Internet access viable for senior citizens or people with special needs (deaf or blind).

Broadband Internet

Broadband Internet is an advanced and revolutionary technology that has allowed high-speed and efficient Internet service and connectivity. It is distinct in its operation from any other from of communication channel or network. In the ordinary base or narrow-band connection used in normal telephone lines, the fastest speed for transmission of data, even after using a speed modem, is only 56 kbps. Advanced technology in broadband allows a substantial amount of information to be carried and processed simultaneously at a faster rate. This leads to greater connectivity or web access, and higher download speeds. The Federal Communication Commission describes broadband as an Internet connection with a download speed higher than 200 kbps. The actual speed, however, can be as high as 256kbps, if not more.

A broadband Internet connection enables multiple data or information, video, image, audio or data signals of different frequencies to be transmitted simultaneously, at very high speed, to different network carriers. Broadband is like a tunnel with high capacity. There are different sub-tunnels, with each tunnel transmitting different information at a high speed. Each sub-tunnel is protected from any interference of disruption from the others. Distance doesn’t affect connectivity, especially in wi-fi and satellite broadband connections.

The broadband Internet connection operates by using several different technologies or media. A traditional dial-up connection uses a telephone line and a modem. The information is converted into analog form, leading to less connectivity and speed. The telephone line cannot be used for normal phone calls when Internet is in use. A broadband Internet connection also uses an existing telephone line for a DSL connection. The information is transmitted using the digital broadband technology; hence, speed and connectivity is higher. The other types include cable broadband connections using existing cable lines, T1 and T3 satellite and wi-fi (wireless fidelity) connections. In case of cable or DSL connection, TV or telephone functioning remains unaffected.

Web Based Time And Attendance Software

Web based time and attendance software has helped to deal with the problem of time tracking, which was one of the most time consuming and costly overhead functions in many organizations. Web-based time and attendance software allows the organization to manage its projects and track time using a standard Web browser. It is an essential package to those business enterprises where similar tasks are assigned to different employees, and the data about the time spent on each task are gathered on daily or weekly basis.

The problems with local timesheet software can be resolved by using Web based time and attendance software. With a Web-based solution, each end user can access the software through any Web browser. As the Web-based applications are usually divided into multiple components, the multi-tiered design is perfectly suited for time and attendance software. This is because the Web-based time and attendance software must support a very large user population, and it should be able to run on a variety of desktops.

Web-based time and attendance software allows the employees to enter their time through a Web interface, view their vacation and sick leave balances, their time sheets, and schedules online. The software reduces use of paper reports and manual processing. Another advantage is that all the employee data can be accessed easily. It is also a quick and easier method for the supervisors to find whether an employee is absent from work or to locate any replacement that may be needed for the day.

There are many factors one should consider while choosing the right Web-based time and attendance software. The purchaser must check the technology of the system, the types of calculations the system performs, how the data works with other systems, and the various ways that data can be collected. Always select a vendor with a good track record x96 this can easily be researched on the Internet.

Data Recovery

Data is information or statistics, numbers or records that are important and are worth being preserved for future use. Data can be stored in various forms and in different sources depending on the type of data, its importance and volume.

These days, data is preferred to be stored in computers and memory storage devices like hard disks, compact discs (CDs), inbuilt memories in computers like Read Only Memory (ROM), Random Access Memory (RAM) or in magnetic tapes. The advantages of storing data in these places are that it is in a uniform manner and it is easily accessible and legible. There are various benefits in storing data in this manner, but certain measures of care are to be taken to safeguard the data that is stored in these specialized memories.

Whenever these memory gadgets are subjected to damage because of extensive heat or any natural calamities, physical tension, accidental damage by computer users, viral infections, accidental reformats or deletions, broken or damaged hard disk drives, the data stored in these systems get corrupted or damaged. Data recovery deals with the restoration of such damaged or lost files in the systems.

Data recovery can be done in two ways depending on the type of damage done to the system or file. The first method of data recovery is physical data recovery wherein the damage is due to external dirt or grim that gets deposited on the memory storage devices.

Another type of data recovery is logical data recovery, where the data is lost due to accidental reformatting of the existing files, accidental deletions or viral infections. Data recovery starts by implementing special software to check and remove any virus present in the affected system. Then data recovery software is used to screen the system and a sector by sector analysis is done. Wherever damage is detected, the data recovery software repairs the damage.

The various types of data recovery are disk data recovery where data is retrieved from damaged disks, hard drive data recovery wherein data is recovered from hard drives and tape data recovery that repairs damaged tapes. Data recovery can be done on different platforms like UNIX based systems like Solaris, Linux and file systems with windows. Data recovery helps overcome the fear of losing important information and data.

Business Intelligence Data Mining

Data mining can be technically defined as the automated extraction of hidden information from large databases for predictive analysis. In other words, it is the retrieval of useful information from large masses of data, which is also presented in an analyzed form for specific decision-making.

Data mining requires the use of mathematical algorithms and statistical techniques integrated with software tools. The final product is an easy-to-use software package that can be used even by non-mathematicians to effectively analyze the data they have. Data Mining is used in several applications like market research, consumer behavior, direct marketing, bioinformatics, genetics, text analysis, fraud detection, web site personalization, e-commerce, healthcare, customer relationship management, financial services and telecommunications.

Business intelligence data mining is used in market research, industry research, and for competitor analysis. It has applications in major industries like direct marketing, e-commerce, customer relationship management, healthcare, the oil and gas industry, scientific tests, genetics, telecommunications, financial services and utilities. BI uses various technologies like data mining, scorecarding, data warehouses, text mining, decision support systems, executive information systems, management information systems and geographic information systems for analyzing useful information for business decision making.

Business intelligence is a broader arena of decision-making that uses data mining as one of the tools. In fact, the use of data mining in BI makes the data more relevant in application. There are several kinds of data mining: text mining, web mining, social networks data mining, relational databases, pictorial data mining, audio data mining and video data mining, that are all used in business intelligence applications.

Some data mining tools used in BI are: decision trees, information gain, probability, probability density functions, Gaussians, maximum likelihood estimation, Gaussian Baves classification, cross-validation, neural networks, instance-based learning /case-based/ memory-based/non-parametric, regression algorithms, Bayesian networks, Gaussian mixture models, K-means and hierarchical clustering, Markov models and so on.

Business Expense Reports

Business Expense Reports are the records of all the expenses incurred by the employees, top level to supervisory level, during their business visits on behalf of the companies. For this purpose, the business organizations should have standard business expense report forms. Nowadays, most of the companies are implementing web-based expense report software like Expense Management Automation (EMA), which automates and quickens the submission, approval and reimbursement processes of the business expense reports.

According to Aberdeen’s research group, EMA helps the business organization in reducing the time required for filling up the expense report by 60%, in decreasing the cost of processing a business expense report by 80% and also in cutting the time required for meeting the claim by 90%. This particular software is supplied by a large number of companies, namely Acceleron, PeopleSoft, SAP, Gelco, Oracle, etc. This software integrates all the processes starting from completing the expense report to receipt processing.

It is true that the employees’ expenses during their business visits occupy a vital role in the total expenses of the business organizations after salaries. According to one survey conducted by a popular Boston-based research organization, it is reported that for every five dollars a company spends, one dollar will be towards employee travel expenses. So companies are taking a very hard look at these expenses. It is observed that most of the business executives are relying on the travel agencies and credit card companies like American Express and Visa International for travel arrangements like ticket booking, hotel accommodations, etc. But, instead, if they make all these arrangements online, there would be a significant cost savings. As per one research survey, such online activity can cut costs by 20 percent. Therefore, online systems are a cost-effective means of controlling travel-related expenses. For trimming the costs, some companies committing to employee-friendly travel policies with their favorite carriers, who will offer discount rates.

Best Passwords

No sane person would ever like someone else reading her email. Or for that matter some other person using her password and breaking into a financial institution. You should, therefore, choose a strong, secure password in such a manner that would be a hard nut to crack for others and easy for you to remember. The more random and mixed-up you make it, the harder it is for others to crack. Mind you, if your password is compromised, the password crackers will even take over your identity.

A password, if too short, is vulnerable to attack if an attacker gets hold of the cryptographic hash of the password. Present-day computers are fast enough to try all alphabetic passwords shorter than seven characters. We can call a password weak if it is short or is a default, or which can be rapidly guessed by searching a subset of all possible passwords such as words in the dictionary, proper names, words based on the user name or common variations on these themes.

On the other hand, a strong password would be sufficiently long, random, or which can be produced only by the user who chose it, so that ‘guessing’ for it will require too long a time.

For maximum security, the user should follow some simple guidelines:

1) Passwords should preferably be at least 8 characters long and not more than 14.

2) Passwords should contain a mix of numbers, letters, and special characters (%&3ac_ht4@m7).

3) Passwords should not contain a dictionary word from any dictionary, be it French, Spanish, medical, etc.

4) Each password should be different from the user’s User-ID and any permutation of that User-ID.

5) New passwords and old passwords should differ by at least 3 characters.

6) Avoid picking names or nicknames of people, pets, or places, or personal information that can be easily found out, such as your birthday, address etc.

7) It’s wise to stay away from common keyboard sequences, such as dfgh678 or abc345 .
8) Never form a password by appending a digit to a word. That can be easily guessed.

9) Avoid writing your password down or storing it on your computer.

10) Never share your password with anyone else.
