Technology Questions and Answers

Answer: D

All three are enabled by 5G, so the answer is 1, 2 and 3.

5G was designed for three kinds of use: very fast mobile broadband, ultra-reliable low-latency communication, and massive machine-type communication. The last connects huge numbers of sensors and devices, the Internet of Things (1). Low latency lets computing be done close to the user at the network's edge, edge computing (2). Network slicing (3) is a core feature of the 5G architecture: one physical network is divided into several virtual networks, each tuned for a different service.

Since all three statements are correct, every option that leaves one out is incomplete.

Answer: D

All four are computer languages, so the answer is All of the above.

Python and Java are among the most widely used programming languages. Cobra is a general-purpose, object-oriented language influenced by Python and C#. Squirrel is a lightweight scripting language, similar to Lua but with C-like syntax, used for scripting in games.

Cobra and Squirrel are less familiar, which makes the narrower options tempting, but both are genuine programming languages.

Answer: D

GPT stands for Generative Pre-Trained Transformer.

ChatGPT, released by OpenAI in November 2022, is built on large language models of the GPT family. They are generative (they produce text), pre-trained on very large amounts of text before being fine-tuned, and based on the transformer neural network architecture.

The other expansions are real but unrelated uses of the letters: glutamic pyruvic transaminase is a liver enzyme measured in blood tests, the GUID Partition Table is a disk partitioning scheme, and the Grooved Pegboard Test is a test of manual dexterity.

Answer: C

The key gives graphite.

Lab-grown diamonds are made by two methods. In the high-pressure high-temperature (HPHT) method, graphite is the carbon source that is converted into diamond at very high pressure and temperature with a metal catalyst; in chemical vapour deposition (CVD), carbon from a gas such as methane is deposited layer by layer. Strictly, the 'seed' on which the crystal grows is a small diamond in both methods, and none of the options is a diamond; the Commission's answer takes graphite, the carbon from which the diamond is formed, as the answer.

The other options are diamond simulants, not diamond material: white sapphire is aluminium oxide, moissanite is silicon carbide, and cubic zirconia is zirconium dioxide. None can become diamond, which is pure carbon.

Answer: D

EDUSAT is a man-made Indian satellite.

EDUSAT (GSAT-3), launched by ISRO in September 2004 on a GSLV rocket, was India's first satellite built exclusively for education, providing interactive classroom links and distance learning across the country.

It is not a rocket (ISRO's launch vehicles are the PSLV and GSLV, which in any case place satellites in orbit around the earth, not the sun), not a planet, and not an asteroid.

Answer: B

The AutoContent Wizard has three steps between Start and Finish.

It asked for the type of presentation, the output medium and the title and footer, then generated an outline with suggested content. It was removed after PowerPoint 2003.

Answer: D

Email can carry audio, pictures and video - any kind of file.

MIME, the Multipurpose Internet Mail Extensions standard, encodes binary data into text so it can travel through mail systems designed for plain characters, and marks its type so the recipient's program can open it.

Answer: B

ROM stands for read only memory.

Its contents are fixed and non-volatile, surviving without power, which is why the firmware that starts a computer is held in it.

Answer: A

C is a third generation high-level language.

Dennis Ritchie created it at Bell Labs in 1972 to rewrite UNIX. It is high level in that it is portable and structured, but close enough to the machine to be used for operating systems.

Answer: C

Turning the computer's ones and zeros into characters a person can read is decoding.

The bits are mapped to characters by a code such as ASCII or Unicode, in which each letter has a numeric value - A is 65 in ASCII.
