CSS MCQs β General Science Abbreviations
- ENIAC β Electronic Numerical Integrator and Calculator
- UNIVAC β Universal Automatic Computer (First Digital Computer)
- EDVAC β Electronic discrete variable automatic computer
- EDSAC β Electronic delay storage automatic calculator.
- All of these were First Generation of Computers. These computers developed between 1946 β 1959, are the first generation of computers. They were large and limited to basic calculations. They consisted of large devices like the vacuum tubes. The input method of these computers was a machine language known as the 1GL or the first generation language. The physical methods of using punch cards, paper tape, and magnetic tape were used to enter data into these computers.

- EEG β Electroencephalogram (CSS 2008, Everyday Science Paper)
- An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.
- ALU βΒ Arithmetic Logic Unit (FIA Test, 19th December, 2021)
- In computing, an arithmetic logic unit (ALU) is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. This is in contrast to a floating-point unit (FPU), which operates on floating point numbers.
- PROMΒ βΒ Β Programmable read-only memoryΒ (FIA Test, 19th December, 2021)
- It is a form of digital memory where the contents can be changed once after manufacture of the device. The data is then permanent and cannot be changed. It is one type of read-only memory (ROM).
