52
Which printer uses a combination of laser-beam & electro photographic techniques.
Discuss
Answer & Solution
Answer: Option A
Solution:
Laser printers : Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text, imagery, or both. As with digital photocopiers, laser printers employ a xerographic printing process.

54
Which of the following is not currently a topic in computer science?
Discuss
Answer & Solution
Answer: Option C
Solution:

55
Where have the program and data to be located before the ALU and control unit of a computer can operate on it?
Discuss
Answer & Solution
Answer: Option A
Solution:
The program and data to be located before the ALU and control unit of a computer can operate on it Internal memory. After calculation/manipulation, the ALU stores the output in an output register. The CPU can be divided into two sections, data section and control section. The DATA section is also known as the data path.

Discuss
Answer & Solution
Answer: Option A

The computer industry has used the term "central processing unit" at least since the early 1960s. Traditionally, the term "CPU" refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.
