Difference between Engineering and Technology

What is the difference between Engineering and Technology ??

      It's quite possible that you may confuse between Engineering and Technology that both are same or different. They are looking like the same thing but has a fine line difference. 

      Let's discuss on it --

Difference between Engineering and Technology 

 

      Engineering and Technology are two so related terms that some times it confuses.

They are closely related but not the same.

      Engineering can be defined as “the profession in which a knowledge of the mathematics and  science gained by study, experience, and practice is applied with judgment to develop ways to utilize economically the materials and forces of nature for the benefit of mankind.”

     In a simpler tone we can say that Engineering is a kind of practical science where we utilise different kind of materials on basis of their properties, develop a process and try to obtain a product.

Computer Science (CS) or Information Technology (IT) !!! Which is better engineering stream ??

      Technology can be defined as “the branch of knowledge that deals with the creation and use of technical means and their interrelation with life, society and the environment.” 

      In a simpler tone we can say that Technology is a kind of process where we develop a kind of product based upon material properties, process complexities and economical aspects.

So in short,

• Engineering is the mind and effort into making something. 

•Technology is the result of application of this mind and effort.

So, at last finally we can say that, 

Available technology is used to engineer more advanced technology.

Which should I opt in between Mechanical Engineering and Civil Engineering ??

What is the "Casting" Process !!! and how these are performed ???

Casting is a fabrication process whereby a totally molten metal is poured into a mold cavity having the desired shape; upon solidification, the metal assumes the shape of the mold but experiences some shrinkage. 

Casting techniques are employed when (1) the finished shape is so large or complicated that any other method would be impractical, (2) a particular alloy is so low in ductility that forming by either hot or cold working would be difficult, and (3) in comparison to other fabrication processes, casting is the most economical. 

Furthermore, the final step in the refining of even ductile metals may involve a casting process. A number of different casting techniques are commonly employed, including sand, die, investment, and continuous casting. Only a cursory treatment of each of these is offered.

                                                

                                                   

INVESTMENT CASTING

For investment (sometimes called lost-wax) casting, the pattern is made from a wax or plastic that has a low melting temperature. Around the pattern is poured a fluid slurry, which sets up to form a solid mold or investment; plaster of paris is usually used. The mold is then heated, such that the pattern melts and is burned out, leaving behind a mold cavity having the desired shape. This technique is employed when high dimensional accuracy, reproduction of fine detail, and an excellent finish are required—for example, in jewelry and dental crowns and inlays. Also, blades for gas turbines and jet engine impellers are investment cast.

 

CONTINUOUS CASTING

At the conclusion of extraction processes, many molten metals are solidified by casting into large ingot molds. The ingots are normally subjected to a primary hot rolling operation, the product of which is a flat sheet or slab; these are more convenient shapes as starting points for subsequent secondary metal-forming operations (i.e., forging, extrusion, drawing). These casting and rolling steps may be combined by a continuous casting (sometimes also termed ‘‘strand casting’’) process. Using this technique, the refined and molten metal is cast directly into a continuous strand which may have either a rectangular or circular cross section; solidification occurs in a water-cooled die having the desired cross-sectional geometry. The chemical composition and mechanical properties are more uniform throughout the cross sections for continuous castings than for ingot-cast products. Furthermore, continuous casting is highly automated and more efficient.

Let’s talk about MEMORY !!!!

Let’s talk about MEMORY !!!!

 

Memory Hierarchy

A memory unit is the collection of storage units or devices together. The memory unit stores the binary information in the form of bits. Generally, memory/storage is classified into 2 categories:

●       Volatile Memory: This loses its data, when power is switched off.

●       Non-Volatile Memory: This is a permanent storage and does not lose any data when power is switched off.

 The total memory capacity of a computer can be visualized by hierarchy of components. The memory hierarchy system consists of all storage devices contained in a computer system from the slow Auxiliary Memory to fast Main Memory and to smaller Cache memory.

 

 

Auxillary memory access time is generally 1000 times that of the main memory, hence it is at the bottom of the hierarchy.

 

 The main memory occupies the central position because it is equipped to communicate directly with the CPU and with auxiliary memory devices through Input/output processor (I/O).

 When the program not residing in main memory is needed by the CPU, they are brought in from auxiliary memory.

 Programs not currently needed in main memory are transferred into auxiliary memory to provide space in main memory for other programs that are currently in use.

 The cache memory is used to store program data which is currently being executed in the CPU. Approximate access time ratio between cache memory and main memory is about 1 to 7~10

Let's discuss today about the “DEVELOPMENT OF MICROSTRUCTURES IN IRON–CARBON ALLOYS”

Today we talk about the “DEVELOPMENT OF MICROSTRUCTURES IN IRON–CARBON ALLOYS”.

Phase changes that occur upon passing from the ϒ region into the ∝ + Fe₃C phase field are relatively complex. 

Consider, for example, an alloy of eutectoid composition (0.76 wt% C) as it is cooled from a temperature within the ϒ phase region, say, 800˚C, that is, beginning at point a and moving down the vertical line xx’. Initially, the alloy is composed entirely of the austenite phase having a composition of 0.76 wt% C and corresponding microstructure. As the alloy is cooled, there will occur no changes until the eutectoid temperature (727˚C) is reached.

 

The microstructure for this eutectoid steel that is slowly cooled through the eutectoid temperature consists of alternating layers or lamellae of the two phases (∝ and Fe₃C) that form simultaneously during the transformation. In this case, the relative layer thickness is approximately 8 to 1. This microstructure point b, is called pearlite because it has the appearance of mother of pearl when viewed under the microscope at low magnifications.

New trends that can help shape the future of Engineering

Digital adoption is a massive opportunity for companies that leverage the right technologies

Cloud Computing

The majority of companies have or will be using some aspect of Cloud computing. The future of Cloud computing will straddle both private and public clouds, adding new challenges to the role of IT.

Artificial intelligence (AI)

AI enables producers to make sense of the overwhelming data that their factories, operations and consumers generate, and to transform that data into meaningful decisions.

Applying AI to the connectivity of Internet of Things (IoT), producers are able to orchestrate and streamline business processes from desktops to machines, across department walls and tiers of suppliers.
