• Computers are designed to store data and execute instructions in bit multiples called bytes.
• One nibble is equal to 4 bits.

Important Points

• Computer storage and memory are often measured in megabytes (MB) and gigabytes (GB).
  • 1 kilobyte (KB) = 1024 bytes
  • 1 megabyte (MB) = 1024 kilobytes
  • 1 gigabyte (GB) = 1024 megabytes
  • 1 terabyte (TB) = 1024 gigabytes
  • 1 petabyte (PB) = 1024 terabytes

Correct Answer is Second Generation

Concept:

Second Generation (1955-1964) computer made was completely based upon transistors. Transistors replaced vacuum tubes in computers. It was invented at Bell Labs by Walter H. Brattain, John Bardeen and William B. Shockley.The TX-0 was the first computer that used transistors, It was released in 1956.These second-generation machines were used for a wide variety of business and scientific jobs and used high-level programming and assembly languages such as FORTRAN (Formula Translator) and COBOL (Common Business Oriented Language).

Additional Information

The second-generation computers had several features: 

• ​Computers made in the second generation used transistors that made them more reliable, smaller in size, faster in speed, more energy-efficient, and cheaper compared to the first generation of computers.
• They contain magnetic storage disks and magnetic core memory.
• They used high-level languages such as FORTRAN and COBOL and allowed communication with the help of a telephone line.
• As compared to the first generation of computers, the data processing time reduced from milliseconds to microseconds.

Key Points

 Option 1: ​It converts the input data and instructions into a computer-acceptable form.

True, The input unit converts these instructions and data into a computer in an acceptable format.

Option 2: It sends input data and instructions to storage devices for storage and further processing.

True, The input device sends input data and instructions to storage devices for storage and further processing.

Option 3: It processes the input data and sends the result directly to the output device.

False, Input devices can send input data or information to a computer or another device. After that, the computer processes the data and sends it back to the output devices like the screen. 

Option 4: It reads data and instructions from the outside world.

True, Input devices Device that accepts data and instructions from the outside world like, Keyboard Mouse Trackball Joystick Light pen Touch Screen Scanner Bar code.

Hence the correct answer is It processes the input data and sends the result directly to the output device.

The correct answer is "Speed".

Key Points

• Gigahertz is a measurement of something happening X times per second.
• 4 gigahertz means that the thing is happening 4 billion times a second.
• When we say that the processor runs at 4ghz we mean that the “main clock” of the processor is ticking 4 billion times per second.
• CPUs are digital circuits. They only do an action when the clock drives the circuit to do the action. Think of that as the RPM of a car. The faster the clock goes, the faster the actions happen.
• For performance, clock speed is important but it's not directly comparable between different CPU architectures. Clock speeds are comparable only in the same family of cpus that share an architecture.

The correct answer is Nibble.

Key Points

• One byte is equal to 8 bits.
• One kilobit is equal to 1000 bits.
• One kilobyte is equal to 8000 bits.
• One kibibit is equal to 1024 bits.
• One kibibyte is equal to 8192 bits.
• One Megabit is equal to 1000000 bits.
• One Megabyte is equal to 8000000 bits. 

The correct answer is I - 3, II - 1, III - 2.

Key Points

• Executing programs:
  • A computer processor executes an instruction, meaning that it performs the operations called for by that instruction.
  • An executable is a file that contains a program - that is, a particular kind of file that is capable of being executed or run as a program in the computer.
• Allocating resources:
  • Resource allocation is the process of assigning and managing assets in a manner that supports an organization's strategic planning goals. 
• Maintain Authorization Information:
  • Authorization is a security mechanism to determine access levels or user/client privileges related to system resources including files, services, computer programs, data and application features.

Explanation:

The startup process of computer system is termed as "Booting". In this, the computer checks whether all the devices are connected properly or not. This is done by a small program in ROM.
