Need help with these CS questions

What does the "flop" part of the petaflop mean? What is the relationship between a teraflop, a mecgaflop, and a petaflop? Computer har____processes da____under the control of sequences of instructions called computer pro ____(also called sof____) which are written by computer pro____. From http: //en.wikipcdia.org./wiki/Moore%27s_law on August 15, 2013 Moore's Law is the observation that, over the history of computing hardware, the number of transistors on integrated circuits doubles approximately every two years. The law is named after Intel co-founder Gordon E. Moore, who described the trend in his paper "Cramming more components onto integrated circuits", Electronics Magazine, April 19, 1965. According to Moore's Law. how many doubling 2-year periods are required for X to increase to at least 100X? Give an example of an input device, an output device, and a secondary storage device. CPU? ALU? CU? How many bits of memory address arc required to address 16GB of main memory? A: 10 B: 16 C: 22 D: 32 E: 34 What is the largest aggregate in the computer industry data hierarchy? A: file B: record C: character D: database E: field What is the smallest aggregate in the computer industry data hierarchy? A: file B: record C: character D: database E: field F: bit Fact All machine languages arc machine-dependent. T or F? A machine can have multiple assembly languages and multiple high-level languages which can be used to write computer programs that arc designed to "run" on the machine. What is the advantage of writing programs in a high-level, machine independent language? How many years old is the C programming language?____the C++ programming language?____When was Java "born"?____

Explanation / Answer

1 peta is 1015 floating Point Operations a Second (flop)

2 Computer hardware processes data under the control of sequence of instructions called computer program (also called software) which are written by computer programmer.

3. it should be almost 14 years.

eg 1990 X,1992 2X, 1994 4X 1996 8X, 1998 16X, 2000 32X, 2002 64X, 2004 128X where X is the speed.

4. Input Device : keyboard

Output Device : printer

secondary storage device : pen drive

5.

CPU: Central processing Unit

ALU: Arithmetic and Logical Unit,part of CPU

CU: Control Unit,part of CPU

6. E. 34

7. D. database

8. F. bit

9. True.

10. Programs written in high level language are abstraction of machine level instructions. We need not use lengthy patterns of 0 and 1 bits in high level languages like in machine level language.

11. C --- 1969

C++ ---- 1983

Java ---- 1991
