Macbook

The MacBook was a brand of Macintosh notebook computers manufactured by Apple Inc. from early 2006 to late 2011. It replaced the iBook series and 12-inchPowerBook series of notebooks as a part of the Apple–Intel transition from PowerPC. Positioned as the low end of the MacBook family, the Apple MacBook was aimed at the consumer and education markets. It was the best-selling Macintosh in history, and according to the sales-research organization NPD Group in October 2008, the mid-range model of the MacBook was the single best-selling laptop of any brand in US retail stores for the preceding five months.

There have been three separate designs of the MacBook: the original model used a combination of polycarbonate and fiberglass casing that was modeled after the iBook G4. The second type, introduced in October 2008 alongside the 15-inch MacBook Pro, used a similar unibody aluminum casing to the 15-inch Pro, and was updated and rebranded as the 13-inch MacBook Pro at the 2009 Apple Worldwide Developers Conference in June 2009. A third design, introduced in October 2009, used a unibody polycarbonate shell as aluminum is now reserved for the higher-end MacBook Pro. On July 20, 2011, the MacBook was quietly discontinued for consumer purchase in favor of the new MacBook Air. Apple continued to sell the MacBook to educational institutions until February 2012. The MacBook has effectively been superseded by the MacBook Air.

Embedded System

An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computingconstraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems control many devices in common use today.

Embedded systems contain processing cores that are either microcontrollers or digital signal processors (DSP).

A processor is an important unit in the embedded system hardware. It is the heart of the embedded system.

The key characteristic, however, is being dedicated to handle a particular task. Since the embedded system is dedicated to specific tasks, design engineers can optimize it to reduce the size and cost of the product and increase the reliability and performance. Some embedded systems are mass-produced, benefiting from economies of scale.

Physically, embedded systems range from portable devices such as digital watches and MP3 players, to large stationary installations like traffic lights,factory controllers, and largely complex systems like hybrid vehicles, MRI, and avionics. Complexity varies from low, with a single microcontroller chip, to very high with multiple units, peripherals and networks mounted inside a large chassis or encl

osure.

Technology

Technology (from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is the making, modification, usage, and knowledge of tools, machines, techniques, crafts, systems, and methods of organization, in order to solve a problem, improve a preexisting solution to a problem, achieve a goal, handle an applied input/output relation or perform a specific function. It can also refer to the collection of such tools, including machinery, modifications, arrangements and procedures. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The term can either be applied generally or to specific areas: examples include construction technology, medical technology, information technology.
and 

The human species' use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fireincreased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons.

Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms.

Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, opining that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition. Indeed, until recently, it was believed that the development of technology was restricted only to human beings, but recent scientific studies indicate that other primates and certain dolphin communities have developed simple tools and learned to pass their knowledge to other generations.

The use of the term technology has changed significantly over the last 200 years. Before the 20th century, the term was uncommon in English, and usually referred to the description or study of the useful arts. The term was often connected to technical education, as in the Massachusetts Institute of Technology (chartered in 1861)."Technology" rose to prominence in the 20th century in connection with the Second Industrial Revolution. The meanings of technology changed in the early 20th century when American social scientists, beginning with Thorstein Veblen, translated ideas from the German concept of Technik into "technology." In German and other European languages, a distinction exists between Technik and Technologie that is absent in English, as both terms are usually translated as "technology." By the 1930s, "technology" referred not to the study of the industrial arts, but to the industrial arts themselves. In 1937, the American sociologist Read Bain wrote that "technology includes all tools, machines, utensils, weapons, instruments, housing, clothing, communicating and transporting devices and the skills by which we produce and use them." Bain's definition remains common among scholars today, especially social scientists. But equally prominent is the definition of technology as applied science, especially among scientists and engineers, although most social scientists who study technology reject this definition. More recently, scholars have borrowed from European philosophers of "technique" to extend the meaning of technology to various forms of instrumental reason, as in Foucault's work on technologies of the self ("techniques de soi").

Dictionaries and scholars have offered a variety of definitions. The Merriam-Webster dictionary offers a definition of the term: "the practical application of knowledge especially in a particular area" and "a capability given by the practical application of knowledge". Ursula Franklin, in her 1989 "Real World of Technology" lecture, gave another definition of the concept; it is "practice, the way we do things around here". The term is often used to imply a specific field of technology, or to refer to high technology or just consumer electronics, rather than technology as a whole. Bernard Stiegler, in Technics and Time, 1, defines technology in two ways: as "the pursuit of life by means other than life", and as "organized inorganic matter."^[

Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems. It is a far-reaching term that may include simple tools, such as acrowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator. Tools and machines need not be material; virtual technology, such ascomputer software and business methods, fall under this definition of technology.^[11]

The word "technology" can also be used to refer to a collection of techniques. In this context, it is the current state of humanity's knowledge of how to combine resources to produce desired products, to solve problems, fulfill needs, or satisfy wants; it includes technical methods, skills, processes, techniques, tools and raw materials. When combined with another term, such as "medical technology" or "space technology", it refers to the state of the respective field's knowledge and tools. "State-of-the-art technology" refers to the high technology available to humanity in any field.

Canon EOS 60D

The Canon EOS 60D is a digital single-lens reflex camera from Canon. It was the first Canon EOS camera which had an articulating LCD screen. It was publicly announced on August 26, 2010 with a suggested retail price of US$1099.00.EOS 50D and preceded the EOS 70D camera.

 As part of the Canon EOS line of cameras, it succeeded the

Apart from its screen, the main new features of the 60D in the two-digit Canon line include increased resolution and ISO range, full-HDvideo capabilities, and in-camera post-processing functions for the images. It uses the DIGIC 4 image processor.

Like the 50D, the camera has a LCD of settings on the top of the camera where the ISO, AF-Mode, Shooting mode, and metering mode can be controlled.

Compared to the EOS 50D the following changes were made:

• Resolution increase to 18.1 megapixels APS-C CMOS Sensor (50D has 15.1 megapixels).
• Maximum sensitivity increased to ISO 6400 (12800 as optional setting) (50D has max 3200 ISO, with 6400 and 12800 as optional settings).
• Video recording, with same controls as the 550D/Rebel T2i.
  • 1080p HD video recording at 24p, 25p and 30p with drop frame timing.
  • 720p HD video recording at 50p (50 Hz) and 60p (59.94 Hz).
  • 480p ED video recording at 50p (50 Hz) and 60p (59.94 Hz).
• Manual control of audio recording (same as newer firmware on 5D MkII).
• Articulating screen (3.0”) with a slightly higher resolution in 3:2 ratio (50D has 4:3).
  • The 60D screen, unlike that of the 50D, matches the aspect ratio of the sensor.
• Lower maximum burst frame rate of 5.3 fps (50D maximum is 6.3 fps).
• SD/SDHC/SDXC card slot (50D uses CompactFlash).
• Smaller and lighter polycarbonate resin with glass fibre on aluminium chassis (50D has magnesium alloy body).
• Wireless Speedlite control.
• Lack of AF micro-adjustment feature (included in 50D).
• Redesign of controls – multi-controller has been relocated to center of quick control dial; top buttons of 60D control only one setting.
• Locking mode dial.
• Electronic level that can be viewed in the viewfinder, rear LCD monitor, and top LCD panel.
• LP-E6 battery, as used in the 5D MkII and 7D.
• Lack of PC socket for flash synchronization.
• External shutter release port changed from 'Canon N3' socket to 3/32" (2.5mm) TRS pin.
• In-camera RAW development and built-in creative filters and special effects.

Digital Photography Review described the changes as representing the move from 'semi-pro'/'prosumer' to 'enthusiast' due to the reduction in some features; however the pentaprism viewfinder and iconic rear control wheel remain, as does the top informational LCD. The slightly smaller body retains the grip of the two-digit Canon line.

Sony Xperia Z

The Sony Xperia Z is a touchscreen enabled, full HD Android flagship high-end smartphone designed, developed, and marketed bySony Mobile.

The phone was announced by Sony at CES 2013 and was released on 9 February 2013 in Japan and 1 March 2013 in the UK. The Xperia Z runs the Android 4.1.2 (Jelly Bean) software. The smartphone has Ingress Protection Ratings of IP55 and IP57, making it dust protected, water-jet protected, and waterproof in up to one meter of water for up to thirty minutes, and features a 13.1MP Exmor RS camera sensor as well as a full HD (1080p) display, encompassed in Sony's Industrial 'Omni-Balance' Design.

A cheaper variant called the Sony Xperia ZL uses the same hardware as the Xperia Z, but sacrifices water resistance for a smaller frame. Another cheaper variant the "Sony Xperia ZR" was announced on 13 May 2013 and is slated to release in "Q2 2013".

In June 2013 images and specifications of a larger phone-tablet hybrid "phablet" version of Sony Xperia Z, called the Sony Xperia Z Ultra (codename: Togari) surfaced, officially being unveiled on 25 June 2013 and is slated to release in "Q3 2013".

On 25 June 2013 the Android 4.2.2 Jelly Bean software update started rolling out for the Sony Xperia Z.

Sony Xperia Z is a rectangular slab that marks a departure from Sony's 2012 design.The design is "OmniBalance", according to Sony, which is focused on creating balance and symmetry in all directions. Xperia Z has subtly rounded edges and smooth, reflective surfaces on all sides, which are held together by a skeleton frame made from glass fibre polyamide. The phone features tempered glass covered by shatterproof film on front and back. The distinctive hall mark of Sony's mobile devices in the form of the aluminium power button is placed on the right side of the device. The location enhances the one-hand operation for the device with 5 inch display. The metallic look and positioning of the power button is inspired by luxury watch crown design.

 The phone is available in three colors; black, white and purple.

Exercise 1 (CSC134)

Computer

A

 computer is general purpose device that can be programmed to carry out a finite set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.

Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU) and some form of memory. The processing element carries out arithmetic and logic operations, and sequencing and control unit that can change the order of operations based on stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.

The Z3 by German inventor Konrad Zuse from 1941 was the first working programmable, fully automatic computing machine. Thus, Zuse is often regarded as the inventor of the computer.

The first electronic digital computers were developed between 1940 and 1945 in the United Kingdom and United States. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). In this era mechanical analog computers were used for military applications.

Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Simple computers are small enough to fit into mobile devices, and mobile computers can be powered by small batteries. Personal computers in their various forms are icons of the Information Age and are what most people think of as “computers”. However, the embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous.

Programming language

Programming language provide various ways of specifying programs for computers to run. Unlike natural language, programming language are designed to permit no ambiguity and to be concise. They are purely written language and are often difficult to read aloud. They are generally either translated into machine code by a compiler or an assembler before being run, or translated directly at run time by an interpreter. Sometimes programs are executed by a hybrid method of the two techniques.

Low-level languages

Machine languages and the assembly languages that represent them (collectively termed low-level programming language) tend to be unique to a particular type of computer. For instance, an ARM architecture computer (such as may be found in a PDA or hand-held videogame) cannot understand the machine language of an Intel Pentium or the AMD Athlon 64 computer that might be in a PC.

Higher-level  languages

Through considerably easier than in machine language, writing long programs in assembly language is often difficult and is also error prone. Therefore, most practical programs are written in more abstract high-level programming languages that are able to express the needs of the programmer more conveniently (and thereby help reduce programmer error).
