Question : Which of the following is not a computer language?
I. C++
II. Java
III. Linux
Option 1: Only I
Option 2: Only III
Option 3: II and III
Option 4: I and III
Correct Answer: Only III
Solution : The correct answer is only III.
A Unix-like computer operating system called Linux was built using the free and open-source software development and distribution model. All general-purpose operating systems have a smaller installed base than Linux.
Question : Who among the following introduced the world's first laptop computer in the market ?
Option 1: Hewlett - Packed
Option 2: Epson
Option 3: Laplink travelling software Inc
Option 4: Microsoft
Correct Answer: Epson
Solution : The correct answer is Epson.
Epson released the world's initial laptop computer to the market in 1981. It was known as the Epson HX-20 and weighed 3.5 pounds. For its day, the Epson HX-20 was a game changer. It was the first battery-powered transportable computer, with a built-in keyboard and monitor. It also contained a printer, which at the time was unusual for portable computers.
Question : Find the part of the given sentence that has an error in it. If there is no error, choose 'No Error'. Producing a different component was as simple such launching a new computer programme.
Option 1: No Error
Option 2: Producing a different component was
Option 3: As simple such launching
Option 4: A new computer programme
Correct Answer: As simple such launching
Solution : The error lies in the third option.
The correct sentence uses the phrase "as simple as" to compare the simplicity of producing a different component to launching a new computer programme. The original sentence had a grammatical error by including "such" inappropriately. The correct structure for making a comparison in this context is "as simple as".
Therefore, the correct sentence should be: "Producing a different component was as simple as launching a new computer programme."
Question : Which of the following devices is used in digital circuits so that information stored in large computer memories is not lost during a momentary electric power failure?
Option 1: Thermistor
Option 2: Diode
Option 3: Transmitter
Option 4: Capacitor
Correct Answer: Capacitor
Solution : The correct option is a Capacitor.
In digital circuits, a capacitor is used to prevent information loss during momentary power failures. It acts as a temporary energy storage device, storing charge and providing a brief power supply to maintain memory integrity. This helps preserve data in computer memories when there is a short disruption in power.
Question : A computer executes programs in the sequence of :
Option 1: Execute, Fetch, Decode
Option 2: Store, Fetch, Execute
Option 3: Fetch, Decode, Execute
Option 4: Decode, Fetch, Execute
Correct Answer: Fetch, Decode, Execute
Solution : The Correct Answer is- Fetch, Decode, Execute
The instruction cycle is divided into four steps: reading the address from memory, decoding the fetched instruction, and finally, executing the instruction. It is completed by the computer processor. The central processing unit keeps doing it from when the computer starts up until it shuts down.
Question : Direction: Madhavi and Shalini are good in drama and Computer Science. Anjana and Madhavi are good in Computer Science and Physics. Anjana, Purnima, and Nirmala are good in Physics and History. Nirmala and Anjana are good in Physics and Math. Purnima and Shalini are good in History and Drama. Who is good in Physics, History, and Drama?
Option 1: Nirmala
Option 2: Purnima
Option 3: Anjana
Option 4: Shalini
Correct Answer: Purnima
Solution : Given: Madhavi and Shalini are good in Drama and Computer Science. Anjana, Purnima, and Nirmala are good in Physics and History. Anjana and Madhavi are good in Computer Science and Physics. Nirmala and Anjana are good in Physics and Math. Purnima and Shalini are good in History and Drama.
Here,
From the above → Purnima is good in Physics, History and Drama.
Hence, the second option is correct.
Question : RAM is used as a short memory in a computer because it:
Option 1: is volatile
Option 2: is programmable
Option 3: has less capacity
Option 4: is very expensive
Correct Answer: is volatile
Solution : The correct option is volatile.
Random-access memory (RAM) is a widely used computing abbreviation. It is also referred to as memory or PC memory. Because RAM is volatile, it serves as the short-term memory for your laptop or computer. Your computer processor needs to know where the data is stored to run your programs and open your files.
A computer purchased on 1st October 2016 for Rs.40,000 debited to Office Expenses Account is to be brought into account on 31st March 2018 charging depreciation @10% p.a. on written down value basis.
Option 1: Revaluation debited by Rs 34,200
Option 2: Revaluation credited by Rs 34,200
Option 3: Revaluation debited by Rs 40,000
Option 4: None of the above
Correct Answer: Revaluation credited by Rs 34,200
Solution : Answer = Revaluation credited by Rs 34200
Office Equipment A/c (Working Note 3)
Dr.
34,200
To Revaluation A/c
Value of Computer on 1st Oct. 2016 40,000
Less: Depreciation on 31st March 2017 (for 6 months) (2,000)
38,000
Less: Depreciation on 31st March 2018 (for 1 year) (3,800)
34,200 Hence, the correct option is 2.
