Static GK decides the General Awareness score in SSC CHSL. Of the 25 questions in Tier-I and the 20 in Tier-II, most come from Indian Polity, History, Geography, the Economy and General Science, the areas the CHSL 2026 notice lists as History, Culture, Geography, Economic Scene, General Policy and Scientific Research relating to India and its neighbouring countries. The level is that of Class 12, so the questions are direct: which article, which river, which ruler, which year. Polity asks about parts and schedules of the Constitution, fundamental rights, the President, Parliament, the Supreme Court and constitutional bodies. History covers the Indus Valley, the Mauryas and Guptas, the Sultanate and Mughal periods, and the freedom struggle from 1857 to 1947. Geography asks about rivers, soils, climate, national parks, minerals and world physical features. The Economy part asks about budget terms, the RBI, banking and basic concepts. General Science is school-level Physics, Chemistry and Biology with everyday applications, and Culture covers dances, festivals, monuments and books. This page holds GK24's topic-wise GK notes for SSC CHSL, written as short facts and tables so a topic can be revised in one sitting. Read a topic, then solve its previous-year questions and quiz on this site to check what you retained.
Indian Army Day is celebrated every year on which date?
On that date in 1949, Field Marshal K. M. Cariappa took over as the first Indian Commander-in-Chief of the Indian Army from the last British officer to hold the post, and the day marks the passing of command into Indian hands.

The Government of India chose his birth anniversary for National Youth Day because his writings and speeches were addressed above all to the young, and his address at the Parliament of Religions in Chicago in 1893 remains the best known moment of his life.
Read the full explanation →Which type of read-only memory can have its contents erased by exposure to ultraviolet light?
A chip of this kind has a small quartz window, and shining ultraviolet light through it clears the stored contents so the chip can be programmed again.
Read the full explanation →The concept of the stored program, on which the architecture of modern computers is based, is credited to whom?
He set out the idea that a computer should keep its instructions in the same memory as its data, so that a program could be loaded and changed like any other information instead of being wired into the machine.
Read the full explanation →PARAM 8000, India's first indigenously developed supercomputer, was built by which organisation?
PARAM 8000 was unveiled in 1991 under the leadership of Vijay Bhatkar, and it made India one of the small group of countries building their own supercomputers.
Read the full explanation →Integrated circuits were the defining electronic component of which generation of computers?
The integrated circuit packs many transistors and other components onto a single silicon chip, and computers built on it were far smaller, cheaper and more reliable than their predecessors.
Read the full explanation →Which unit of the CPU decodes instructions and directs the working of the other units without performing any calculation itself?
It fetches each instruction from memory, decodes it, and then issues signals that tell the other parts of the system what to do and when.
Read the full explanation →How many bits make one nibble?
A bit is the smallest unit of data, holding a single binary 0 or 1. Four bits together form a nibble, which is exactly half a byte, and a nibble is convenient because it maps neatly to one hexadecimal digit.
Read the full explanation →Which of the following is a volatile memory?
Random access memory holds the programs and data the processor is working on at that moment, and it is volatile: the instant the power supply is cut, everything stored in it disappears.
Read the full explanation →In which year was the Intel 4004, the first commercial microprocessor, introduced?
The Intel 4004 placed an entire processing unit on a single chip for the first time in a commercial product, and that step marks the beginning of the fourth generation of computers, built on very large scale integration.
Read the full explanation →Which of the following is regarded as the first commercially available electronic computer?
It was the first electronic computer built to be sold to customers rather than used only in a laboratory, and it was famously put to work on census and business data processing.
Read the full explanation →The transistor, which defined second-generation computers, was invented at which laboratory?
John Bardeen, Walter Brattain and William Shockley demonstrated the transistor there in 1947, and the three shared the Nobel Prize in Physics for it.
Read the full explanation →Vacuum tubes were used as the main electronic component in which generation of computers?
Machines such as ENIAC, EDVAC and UNIVAC-I ran on thousands of vacuum tubes, which made them enormous, power-hungry and dependent on constant cooling.
Read the full explanation →Who is known as the Father of the Computer?
He designed the Difference Engine and then the Analytical Engine, and the Analytical Engine contained the logical parts of a modern computer: a store for holding numbers, a mill for calculating, punched-card input and a printed output.
Read the full explanation →The Bhagavad Gita forms a part of which larger work?
The Bhagavad Gita is a section of the Bhishma Parva of the epic, in which Krishna counsels Arjuna on the battlefield of Kurukshetra.
Read the full explanation →Ashvaghosha, the author of Buddhacharita, is associated with the court of which ruler?
Ashvaghosha wrote the Buddhacharita, a life of the Buddha in Sanskrit verse, and also Saundarananda, and tradition places him at Kanishka's court along with the physician Charaka and the Buddhist scholar Vasumitra.
Read the full explanation →The Panchatantra, a collection of animal fables composed to instruct princes, is ascribed to whom?
The Panchatantra, meaning the five treatises, uses talking animals to teach practical wisdom and statecraft, and the frame story explains that it was composed to educate princes who had no taste for formal learning.
