Electrically Erasable Programmable Read Only Memory is erased by applying a voltage, one byte at a time, while the chip stays soldered in place, which is why it is used for settings that must survive a power cut and yet be changed occasionally, such as the configuration data of a…

The 3.5-inch high-density floppy disk, the square plastic diskette with a metal shutter, was formatted to 1.44 MB, and that figure is still asked in computer awareness papers because it anchors the small end of the capacity ladder.

An SSD is built from flash memory, itself a block-erasable form of EEPROM, which traps charge in floating-gate cells.

The operating system reserves an area of the hard disk, called the swap space or the page file, and moves pages a program is not actively using out to it.

Cache is a small block of static RAM that keeps the instructions and data most recently used by the processor.

A Digital Versatile Disc uses a shorter wavelength laser and finer pits than a compact disc, so one side with one recording layer holds about 4.7 GB; a double-layer disc of the same size holds roughly 8.5 GB.

Random Access Memory holds a bit only while it is powered, whether the cell is a flip-flop in static RAM or a leaking capacitor in dynamic RAM.

Every step in the ladder of storage units multiplies by 1,024, because 1,024 is 2 raised to the power 10 and memory is addressed in binary.

An Erasable Programmable Read Only Memory chip carries a small quartz window over the silicon; ultraviolet light shone through that window releases the trapped charge from every cell at once and returns the chip to its blank state, after which it can be programmed again.

Dynamic RAM stores each bit as a charge on a very small capacitor, and that charge leaks away in a few milliseconds, so the memory controller has to read and rewrite every cell continuously.

A nibble is half a byte, that is four binary digits, and it matters because one nibble is written as exactly one hexadecimal digit, from 0 to F. That is why memory addresses in hexadecimal are read four bits at a time.

A register is built into the CPU itself and holds the word the arithmetic and logic unit is operating on at that instant, so it is read and written in a single clock cycle.

He was a Hindi poet long before he became Prime Minister, and Meri Ekyavan Kavitayen is his best-known collection. Kaidi Kavirai Ki Kundaliyan holds verses written during the Emergency, and Meri Sansadiya Yatra collects his speeches in Parliament.

Exam Warriors is written for school students facing examinations and sets out short chapters on preparation, sleep, play and dealing with pressure.

His autobiography, Matters of Discretion, covers a career that ran from the freedom movement through the ministries he held to his term as Prime Minister, and it is the book usually cited alongside the foreign policy approach that carries his name.

He had a long career in Gujarat and at the centre before becoming Prime Minister at the head of the first non-Congress government, and the book covers that whole span.

Nehru wrote the letters from prison in the early 1930s to explain the history of the world to a young reader, and they were later collected as Glimpses of World History.

These are the second and third volumes of his political memoir, the first being The Dramatic Decade: The Indira Gandhi Years.

His account of the office, published as My Presidential Years, is valued because his term fell in a period of short-lived governments, and it records how a President handles the choice of a Prime Minister when no party has a majority.

Besides these two titles he wrote Indian Philosophy in two volumes and The Philosophy of the Upanishads, and Teachers' Day is observed on his birthday, 5 September.
