Question
Chapter 3, Problem 2CE
Program Plan Intro
Components of computer:
Computer has four major components, they are:
- Central processing unit (CPU)
- Memory unit
- Input devices
- Output devices
Central Processing Unit (CPU):
- CPU plays the key role in a computer by carrying out instructions of a computer program.
- It performs all the basic logic, arithmetic, controlling and input/output operations that are specified by the instructions.
- The CPU comprises of two units, Arithmetic logic unit (ALU) and control unit (CU).
Memory unit:
- Once computer program instructions set are transformed into machine code by CPU, the machine code is stored in memory.
- Then the CPU fetches the required data and instructions from memory, perform the required operations and then sends the result and next set of instructions back to memory.
Input devices:
- The devices used by the user to feed information to computer, such as a hard drive, keyboard, or a networking card.
- These devices get the data from outside world into computer in the way that human eyes and ears bring the data to brain.
Output devices:
- Output devices are used by computer to deliver the information to the user, such as a monitor, printer, and speaker.
- The CPU takes the machine code present in memory and converts it into a format that is required by monitor’s hardware.
- Then the monitor’s hardware alters that information into different light intensities such that words or pictures are seen.

Your employer has an annual revenue of $50 million and employs 500 people. It intends to purchase 100 new laptop computers. You have been appointed by the chief financial officer to lead a project team charged with defining users' computer hardware requirements and recommending the most cost-effective solution to meet those requirements. Who else (job, department) and how many other team members would you select? How would you go about defining the demands of your users? Do you believe that there will be a single type of portable computer that will fulfill everyone's needs? Should you define numerous portable computers to meet the requirements of diverse end user classes? What business reason can you provide for this approximately $100,000 expenditure?
Your company ABC manufactures computer components, and you're the CEO of the company (motherboards, hard drives, RAM, etc.). To control expenditures and reduce costs in your company's financial situation, you calculate how many employees are needed to maintain high-quality goods and services. How can these personnel costs be kept in check?
Rod Rodriguez wants to buy 20 computers for his business, Robust Rods, Inc. He has asked you to help him with that project. Rod actually wants you to give him three estimates: one estimate right away, another estimate using your experience from the past, and a third estimate in a detailed manner. Provide him all three estimates. His specifications are as follows:
The best processor available;
The latest operating system;
Largest memory possible;
At least 1 TB of storage;
A good-size monitor;
DVD+R double layer write capability; and
A good warranty program.
