Why Do We Need Software Engineering?
RecoverySoft / August 14, 2018

To understand the necessity for software engineering, we must pause briefly to look back at the recent history of computing. This history will help us to understand the problems that started to become obvious in the late sixties and early seventies, and the solutions that have led to the creation of the field of software engineering. These problems were referred to by some as “The software Crisis,” so named for the symptoms of the problem. The situation might also been called “The Complexity Barrier,” so named for the primary cause of the problems. Some refer to the software crisis in the past tense. The crisis is far from over, but thanks to the development of many new techniques that are now included under the title of software engineering, we have made and are continuing to make progress. In the early days of computing the primary concern was with building or acquiring the hardware. Software was almost expected to take care of itself. The consensus held that “hardware” is “hard” to change, while “software” is “soft,” or easy to change. According, most people in the industry carefully planned hardware development but gave considerably less forethought to the software. If the software…

Activity Diagrams – Advantages, Disadvantages and Applications of Use
RecoverySoft / August 14, 2018

Activity diagrams describe the actual work flow behavior of a system in Information Technology. These diagrams are very similar to state Diagrams because activities are the actual state of doing something. These diagrams describe the actual state of activities of a system by showing all the sequence of activities performed. Also, these diagrams can show activities that are conditional or parallel. When to Use: Activity Diagrams Activity diagrams should be used in alignment with other modeling techniques like interaction diagrams and State diagrams. The main reason behind using these diagrams is to model the work flow behind the system being designed. these Diagrams are also useful for analyzing a use case by describing what actions need to take place and when they should occur, describing a complicated sequential algorithm and modeling applications with parallel processes. Activity diagrams’ advantages: UML modeling language included that these diagrams are normally easily comprehensible for both analysts and stakeholders. In UML for the IT Business Analyst, “The activity diagram is the one most useful to the IT BA for depicting work flow [because] it is simple to understand-both for BAs and end-users.” Since they are among the most user-friendly diagrams available, they are generally regarded…

Data Recovery Services – Be Wary of Cheap Prices
RecoverySoft / August 13, 2018

Data recovery is a specialized, complicated process. Proper hard drive recovery can require manipulation of data at the sector level, transplantation of internal components and various other procedures. These techniques are very involved and require not only talented, knowledgeable technicians, but also an extensive inventory of disk drives to use for parts when necessary and clean facilities to conduct the work. Unfortunately these factors mean that, in most cases, recovery services are quite expensive. Technician training, hard drive inventories and special equipment all come with a cost. If you search for disk recovery services, you will likely find several smaller companies that offer hard disk data recovery for a fraction of the prices typically quoted by larger, more experienced organizations. These companies often operate from small offices or, in some cases, private homes. They do not possess clean room facilities, large disk drive inventories or many other pieces of equipment necessary to successfully complete most hard drive recovery cases. When you take into account all of the training, parts and facilities necessary, you can see how it is impossible for a company to charge $ 200 for a hard drive recovery and not operate at a loss. What these companies…

The KWP2000 Protocol in Automotive Diagnostic Applications
RecoverySoft / August 8, 2018

The KWP2000 protocol has become a de facto standard in automotive diagnostic applications. It is standardized as ISO 14230-3. KWP2000 describes the implementation of various diagnostic services you can accethrough the protocol. You can run KWP2000 on several transport layers such as K-line (serial) or CAN. Transport Protocol As KWP2000 uses messages of variable byte lengths, a transport protocol is necessary on layers with only a well defined (short) message length, such as CAN. The transport protocol splits a long KWP2000 message into pieces that can be transferred over the network and reassembles those pieces to recover the original message. KWP2000 runs on CAN on various transport protocols such as ISO TP (ISO 15765-2), TP 1.6, TP 2. 0 (Volkswagen), and SAE J1939-21. For KWP2000, the Automotive Diagnostic Command Set supports only the ISO TP (standardized in ISO 15765-2) and manufacturer-specific VW TP 2.0 transport protocols. Diagnostic Services The diagnostic services available in KWP2000 are grouped in functional units and identified by a one-byte code (ServiceId). The standard does not define all codes; for some codes, the standard refers to other SAE or ISO standards, and some are reserved for manufacturer-specific extensions. The Automotive Diagnostic Command Set supports the following…

Difference Between Web 1.0, Web 2.0, & Web 3.0 – With Examples
RecoverySoft / August 7, 2018

Like any other technology, the web is evolving and it is evolving rather quickly. Due to lack of standards, there seems to be a little bewilderment regarding its evolution and versions but the most acceptable stages of evolution are as follows:   Web 1.0 Web 2.0 Web 3.0 (Also known as Semantic Web) So, what is the difference between these versions? Web 1.0: The Internet before 1999, experts call it Read-Only era. The average internet user’s role was limited only to reading the information presented to him. The best examples are millions of static websites which mushroomed during the.com boom. There was no active communication or information flow from consumer of the information to producer of the information. Web 2.0: The lack of active interaction of common user with the web lead to the birth of Web 2.0. The year 1999 marked the beginning of a Read-Write-Publish era with notable contributions from LiveJournal (Launched in April, 1999) and Blogger (Launched in August, 1999). Now even a non-technical user can actively interact & contribute to the web using different blog platforms. This era empowered the common user with a few new concepts viz. Blog, Social-Media & Video-Streaming. Publishing your content is…
