47
Q

What are today’s programs written with?

A

High-level programming language such as Python or Java.

48
Q

What key innovation set the EDVAC apart from its predecessor (the ENIAC)?

A
  1. First, the EDVAC would have a much larger memory and would store numbers and perform arithmetic in binary. (The ENIAC used decimal internally, not binary.)
  2. Second, the EDVAC would store both the program’s data and instructions in the same memory. This concept would eventually be known as “the stored program concept.”
  3. Third, instructions for the computer would be represented as a system of binary codes. Each instruction would consist of a single operation code, optionally followed by one or more
49
Q

In the 1950s’, what was the assumption regarding the invention of computers depending as to their customer?

A

Both large and small numbers with a high degree of precision (down to the smallest decimal)

57
Q

What science-oriented IBM machine had dedicated hardware to perform floating point arithmetic?

A

IBM 704; could perform really fast calculations

A

True, they were just slower

59
Q

Why did the IBM machines dedicated to businessmen not include hardware that was dedicated to the floating-point arithmetic?

A

It was assumed that business users did not the added precision

60
Q

True or False? The IBM System/360 was only met for science uses?

A

False; it was meant for business and science uses as the decreasing cost in hardware and the complexity of marketing different machines to a variety of customers led IBM to unify its platforms

61
Q

What two IBM machines were introduced in 1959 that used core memory and transistors for scientific use?

A

7090 and 7094

62
Q

What IBM machines was introduced in 1960, and similar to the IBM 7090 and 7094, used core memory and transistors but was intended for business use?

A

1401

63
Q

What made software increasingly expensive to maintain and why it was not very common?

A

Because customers could not switch IBM machines without having to scrap their existing application/program as the program of one computer would not work for another

64
Q

What was IBM’s solution to the incompatibility of their machines?

A

To make a “family” of compatible computers with different price points

65
Q

The name “360” of System/360 comes from…?

A

the number of degrees in a circle, implying this model spanned the “full circle” of a customers needs

66
Q

IBM initially announced how many models of System/360 in April 1964?

A

6

67
Q

What was the speed difference from the fastest model of System/360 to the slowest?

A

25:1

68
Q

How is the “family” of IBM System/360 similar to modern day phones or computers?

A

We are able to transfer data saved on one device to another without recompilation

69
Q

True or False? Microprogamming is necessary for the System/360?

A

True as it created a single unified instruction set for each platform in which the fastest models would run the program natively and slower models had a microprogram that’d provide slower implementations of the instruction

70
Q

What was a consequence of microprogramming?

A

Allowed the System/360 to emulate other types of computers, meaning some people could run their old IBM 1401 on the System/360 machines for it to be 10 times faster

71
Q

What is an operating system?

A

a program that coordinates all parts of the computer– memory, processor, disk/tape drives, card readers, printers, application software– to allow them to work together

72
Q

True or False? Was multiprogramming (multitasking) used in the OS/360.

A

True as it allowed for multiple programs to be ran at the same time

73
Q

What was a major flaw in the System/360?

A

Its operating system (OS/360) as it was very complex

74
Q

Who was the manager of the OS/360?

A

Fred Brooks

75
Q

Why was the OS/360 released in 1967, a year behind schedule?

A

Because of its complexity despite there being 1000 people working on it at some point. Four smaller operating machines were released from 1965 to 1967 as a stop gap measure

76
Q

Who published The Mythical Man-Month?

A

Fred Brooks

77
Q

What was The Mythical Man-Mouth about?

A

the lessons Brook’s learned from working on the OS/360 project as a collection of essays

78
Q

What is Brook’s Law?

A

Adding manpower to a late software project makes it later

79
Q

What is the meaning of Brook’s Law?

A

since programming requires primarily mental, not physical effort: With there being more people, the original programmers must explain how to do it and answer questions from the extra man, therefore, more time is spent talking/explaining than actually focusing on the “real” work

80
Q

What is software engineering?

A

the practice of writing software using standardized processes, based on engineering
principles; well-engineered software is typically easier to maintain over time and has fewer bugs.

81
Q

The issues of the OS/360 team motivated what industry-wide movement?

A

Beginning with the first NATO-sponsored software conference in 1968

82
Q

Drawbacks to the success of the IBM System/360

A

As IBM was so focused on maintaining/improving System 360, it was slow to embrace other inventions such as the personal computer in the 1970s’

83
Q

When was Eckert and Mauchly’s original patent published?

A

1964, since it was a long time, ENIAC had already been supplanted by new machines

84
Q

Who was the current corporate owner of the ENIAC patent?

A

Sperry Rand

85
Q

What did Sperry Rand claim?

A

the patent covered all electronic computers in general and, therefore, he demanded royalty payments from other computer manufacturers

86
Q

What did Judge Earl Larson decide regarding the case with Sperry Rand?

A

Striked down the ENIAC patent and said the invention of the computer was in the public domain. Anyone was free to create and sell computers without having to pay royalty fees.

87

A

cash registers

88
