Q1: What Do Business Professionals Need to Know

About Computer Hardware?

• Central processing unit (CPU) - “the brain”.

• Dual-processor and Quad-processor computers.

• CPUs vary in speed, function, and cost.

• CPU works in conjunction with main memory (RAM)

• CPU reads data and instructions from memory, and stores

results of computation in memory.

Specifying Hardware with Computer Data Sizes

• Computer disk capacities are specified according to the

amount of data they can contain

• CPU speed is expressed in cycles called hertz.

– Slow personal computer speed of 1.5 Gigahertz

– Fast PC 3+ Gigahertz, with dual processors.

• CPUs classified as 32-bit or 64-bit.

– Need a 64-bit processor to effectively use more than 4GB

of memory.

: Source code is compiled into instructions executed directly by

a computer’

s CPU

How Does Open Source Work?

Closed-source or p roprietary softwar e

source code is not available to users or public

Only available to trusted

employees and carefully vetted contractors

Open-source soft ware

available to users in source code form.

C o p y r i g h t © 2 0 1 5 P e a r s o n E d u c a t i o n , I n c

So, Is Open Source Viable?

• Depends on requirements and constraints of situation.

• “Free” open source software still requires support and

operational costs that could cost more than a licensing fee.

• Future will involve a blend of both proprietary and open

source software.

Q4: What Are the Differences Between Native and

Thin-client Applications? (cont'd )

C o p y r i g h t © 2 0 1 5 P e a r s o n E d u c a t i o n , I n c

Developing Thin-client Applications

• Major advantage of thin-clients over native applications is

they run on any operating system and device.

• Development languages are HTML5, CSS3, and Javascript.

• Thin-client applications are limited by capabilities of browser.

• Written by professional programmers, technically oriented

Web developers and business professionals.

• Users obtain thin-client applications via the Web.
