Key takeaways

  • List of BlackBerry products belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect List of BlackBerry products to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of List of BlackBerry products from memory before moving on to harder problems.

Reference excerpt

The following is a partial list of BlackBerry products. BlackBerry is a line of wireless handheld devices first introduced in 1996 and manufactured by the Canadian company BlackBerry, formerly known as Research In Motion (RIM).

Early pager models These two-way pager models had thumb keyboards, with a thumbwheel for scrolling its monochrome text display. The first model, the Inter@ctive Pager, was announced on September 18, 1996. Within a year, Yankee Group was estimating that devices like the Inter@ctive Pager were in use by fewer than 400,000 people and expected two-way wireless messaging services to attract 51 million users by 2002. They provided e-mail and WAP services, with limited HTML access provided via third party software such as WolfeTech PocketGenie or GoAmerica browser. They were built for use with two 1G data-only packet switched networks: Mobitex and DataTAC. They did not support Java without the use of a Java Virtual Machine add-on.

Monochrome Java-based models (5000 and 6000 series) Most of these models were the first BlackBerry models that had a built-in mobile phone, were the first models that natively ran Java, and transmitted data over the normal 2G cellular network. RIM began to advertise these devices as email-capable mobile phones rather than as two-way pagers. At this time, the primary market was still businesses rather than consumers. The 5810 was released on March 4, 2002. An aberration in this list, the 5790, was released at a much later date as a niche model in 2004 after many color BlackBerry models were out. This non-phone BlackBerry was made available due to the demand for a Java-based model that could run on the Mobitex data-only network. The 5810/5820 shared the same physical casing and keyboard layout as the earlier 957 device. The 6000 series was launched in 2003 with 6210 entering the influential Time All Time 100 Gadgets list.

First color models (7000 series) In 2003, the monochrome models were revised to include a color screen, while retaining the same form factor and casing. Early color models, such as the 7230, typically used a dim electroluminescent backlight, leading to an initial reputation of poor image quality. Later color models, such as the 7290, typically used a LED backlight, yielding much better screen quality. The color LCD screens used in these series were either reflective or transflective, so these screens yielded better image quality in direct sunlight even with the backlight turned off. Nearly all models in this list were 16 MB models with no Bluetooth. The only model with 32 MB and Bluetooth is the 7290, which was the last model released in the early BlackBerry form factor, and was the first BlackBerry model with Bluetooth. The 7290 was also the first quad-band BlackBerry. An aberration in this list is the 7270, the first Wi-Fi BlackBerry, released later. It is built into the old form factor in the same vein as the 7200 series.

First SureType models (7100 series) RIM expanded the market by introducing the first BlackBerry models without a discrete QWERTY keyboard, in the candybar form factor. They developed a predictive text technology called SureType with a QWERTY-like layout, using two keys per button. By using only two letters per button, rather than three letters per button as in T9 using ten-digit keypads, predictive text accuracy could be improved dramatically. The use of a QWERTY-like layout took advantage of people's memory of the computer keyboard, since each button was roughly relative to each key. At the same time, the size of the BlackBerry could be dramatically reduced, as keyboards only needed to be 5-buttons wide rather than 10-buttons wide. These BlackBerries became more popular with the mass market as they became similarly sized to competing consumer-market cellphones. These models were among the first BlackBerry models to be aggressively marketed to consumers, rather than to businesses. RIM continued to manufacture QWERTY models, to give the market a choice between the traditional QWERTY thumb keyboard, and the compressed SureType keyboard.

Consumer models (8000 and 9000 series)

Beginning with the 8700-series models in 2006, RIM began to aggressively add consumer features to BlackBerry models, in an aim to capture more of the consumer market from competitors such as Treo, Nokia Eseries, and Motorola Q. In this progression of models, the additions include better quality screens, more memory, built-in chat software, cameras, microSD memory card support, built-in mapping software, and other consumer-specific features. The BlackBerry Pearl 8100 was the first BlackBerry without a trackwheel, which was replaced by a miniature trackball to enable full 4-way and mouse-style navigation on a BlackBerry. The look of the new trackball gave the "Pearl" its name. The 9000 series was launched in 2008.

Worked examples

Example 1 — a first encounter with List of BlackBerry products

Start with the simplest possible case. Write down what List of BlackBerry products claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of BlackBerry products before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of BlackBerry products ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of BlackBerry products

In research
List of BlackBerry products appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses List of BlackBerry products in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
List of BlackBerry products is common in secondary-school and first-year university syllabi. It links to neighbouring topics BlackBerry, BlackBerry Limited, BlackBerry Limited smartphones, so understanding it makes those chapters shorter.
In everyday life
Look for List of BlackBerry products outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
