S2 Chapter 1 Solutions
1.1.14 Program that translates symbolic instructions to binary instructions:
21 assembler
1.1.15 High-level language for business data processing: 25 cobol
1.1.16 Binary language that the processor can understand: 19 machine language
1.1.17 Commands that the processors understand: 17 instruction
1.1.18 High-level language for scientifi c computation: 26 fortran
1.1.19 Symbolic representation of machine instructions: 18 assembly language

bytes: 6 terabyte
Solution 1.2
1.2.1 8 bits × 3 colors = 24 bits/pixel = 4 bytes/pixel. 1280 × 800 pixels = 1,024,000
pixels. 1,024,000 pixels × 4 bytes/pixel = 4,096,000 bytes (approx 4 Mbytes).
1.2.2 2 GB = 2000 Mbytes. No. frames = 2000 Mbytes/4 Mbytes = 500 frames.
1.2.3 Network speed: 1 gigabit network ==> 1 gigabit/per second = 125 Mbytes/
second. File size: 256 Kbytes = 0.256 Mbytes. Time for 0.256 Mbytes = 0.256/125 =
2.048 ms.
