Answer: (c)

Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors.

Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output.

Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN.

Answer: (b)

An operating system is a program that acts as an interface between the user and the computer hardware and controls the execution of all kinds of programs.

An Operating System (OS) is an interface between a computer user and computer hardware. An operating system is software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.

Answer: (c)

A scanner, image scanner, or optical scanner is a hardware input device that optically "reads" an image and converts it to a digital signal. For example, a scanner may be used to convert a printed picture, drawing, or document (hard copy) to a digital file that can be edited on a computer

Answer: (b)

The Word length of a Personal Computer is 8 bits.

The most common processors are/were 8-bit, 16-bit, 32-bit or 64-bit. These are the WORD lengths of the processor. Actually, half of a WORD is a BYTE, whatever the numerical length is. Ready for this, half of a BYTE is a NIBBLE. A byte may have more than or fewer than 8 bits. The term 'word' is used to describe the number of bits processed at a time by a program or operating system. So, in a 16-bit CPU, the word length is 16 bits. In a 32-bit CPU, the word length is 32 bits.

The hardware registers in a computer machine are word-sized. ... In this context, a word is a unit that a machine uses when working with memory. For example, on a 32-bit machine, the word is 32 bits long and on a 64 bit is 64 bits long. The word size determines the address space.
