- Question
"FET" is a type of transistor, Its full name is ________ Effect Transistor...?
Options- A. Field
- B. Factor
- C. Flash
- D. Force
- Correct Answer
- Field
ExplanationThe terminals of FETs are called gate, drain and source. You might be more familiar with bipolar junction transistors (BJTs), which have terminals called base, collector and emitter. FETs were conceptualized first, but BJTs were easier to produce and so developed sooner. - 1. 'DB' computer abbreviation usually means?

Correct Answer: Database
Correct Answer: Japan
Correct Answer: Animation/movie file
Correct Answer: Variable Voltage Variable Frequency
Explanation:
It is a method of controlling the speed of an AC induction motor, whereby speed, current and torque can all be accurately controlled.
Correct Answer: Backup file
Correct Answer: 1900s
Explanation:
On December 12, 1901, a radio transmission received by Guglielmo Marconi resulted in the first transmission of a transatlantic wireless signal (Morse Code) from Poldhu, Cornwall, to St. John's, Newfoundland.
Correct Answer: "lo"
Correct Answer: Alternating Current and Direct Current
Explanation:
Electricity is voltage and current. Voltage is electrical pressure, and current is the flow of charged particles. The difference between alternating current (AC) and direct current (DC) is that the electrons in an AC circuit regularly reverse their direction. In a DC circuit electrons always flow in the same direction.
Correct Answer: Capacitor
Explanation:
Useful in tuning and filtering circuits, it blocks DC while passing AC. How much charge a capacitor can store is its capacitance, measured in farads.nn
Correct Answer: Phil Zimmermann
Explanation:
Phil Zimmermann created the first version of PGP encryption in 1991. Pretty Good Privacy (PGP) is a data encryption and decryption computer program that provides cryptographic privacy and authentication for data communication. PGP is often used for signing, encrypting and decrypting texts, E-mails, files, directories and whole disk partitions to increase the security of e-mail communications.
