ARPANET was the first military-academic network that marked the early development of the
Internet in 1969.
Data are unprocessed values, while information is
organized or analyzed data that becomes meaningful.
Cybersecurity aims to protect digital systems, networks, devices, and data.
What was the original purpose of ARPANET?
The original purpose of ARPANET was to enable secure and reliable communication between
military and research institutions and allow resource sharing among connected computers.
quadrilaterals 1. The sum of the interior angles of a quadrilateral is 360°.
2. In a parallelogram:
(a) Opposite sides are equal.
(b) Opposite angles are equal.
(c) Consecutive angles are supplementary (sum = 180°).
(d) Diagonals bisect each other.
(e) A diagonal divides it into two congruent triangles.
3. A quadrilateral is a parallelogram if:
(a) Both pairs of opposite sides are equal.
(b) Both pairs of opposite angles are equal.
(c) Diagonals bisect each other.
CHAPTER 1: ACCOUNTING INFORMATION SYSTEMS (AIS)
What Is a System?
A system is two or more interacting parts (subsystems) working together to achieve one or more goals.
Example:
A company is a system.
• Sales department
• Accounting department
• HR department
All work together to earn profit.
Goal Conflict
Occurs when one subsystem’s goal hurts the overall organization.
Example:
Sales offers heavy discounts to increase sales numbers, but profits fall.
Goal Congruence
Occurs when subsystem goals...

Enunciat: Una màquina de vapor que extreu Qh=700 MJ de la font calenta (Th=600 ºC), fa un treball net W=300 MJ. La font freda està a Tc=120 ºC. Determineu:
a) Rendiment de Carnot (Teoric): E_c = 1 - (Tc_K / Th_K) = 1 - (393 / 873) = 0,5498 = 54,98%
b) Treball màxim: W_max = Qh * E_c = 700 * 0,5498 = 384,86 MJ
c) Rendiment real: E_r = W / Qh = 300 / 700 = 0,4285 = 42,85%
d) Treball perdut: W_i = W_max - W = 384,86 - 300 = 84,86 MJ

Opposite charges attract → bond forms.
Ionic bonds are relatively weak in water. Water can break them apart (dissociation)
