Key Insights - 3 Insights

Why do we assess hardware capabilities after determining software needs?

Because software requirements define what hardware is necessary to run them properly, as shown in step 3 of the execution_table.

Why is network requirement checked separately from hardware?

Network needs depend on software and tasks that require connectivity, which is different from hardware specs like CPU or memory, as seen in step 4.

How do security needs influence platform specifications?

Security needs add requirements like encryption or access controls that must be included in the final platform specs, as step 5 feeds into step 6.

Full Transcript

To determine computing platform requirements, start by identifying what users need to do. Then find out what software supports those tasks. Next, check what hardware is needed to run that software well. After that, consider network needs for connectivity and speed. Also, evaluate security needs based on data sensitivity. Combine all these to define the platform specifications. Finally, select or build a platform that meets these requirements. This step-by-step process ensures the platform fits user needs and technical demands.

Practice

1. What do computing platform requirements mainly tell you?

easy

A. The hardware and software needed to run a program

B. The price of the software

C. The number of users allowed

D. The color scheme of the software interface

Solution

1. Step 1: Understand the meaning of platform requirements

   Platform requirements specify what hardware and software are necessary for a program to work properly.

2. Step 2: Identify the correct description

   Among the options, only the hardware and software needs match the definition of platform requirements.

3. Final Answer:

   The hardware and software needed to run a program -> Option A

4. Quick Check:

   Platform requirements = hardware and software needs [OK]

Hint: Platform requirements = hardware + software needed [OK]

Common Mistakes:

• Confusing requirements with software price
• Thinking requirements limit user numbers
• Assuming requirements describe interface design

2. Which of these is a correct example of a computing platform requirement?

easy

A. Needs a password to open the software

B. Must have a blue screen background

C. Requires at least 4 GB RAM and Windows 10 or higher

D. Only works on smartphones made in 2010

Solution

1. Step 1: Identify hardware and software specs

   Platform requirements usually specify minimum hardware (like RAM) and software versions (like OS).

2. Step 2: Match options to this definition

   Requires at least 4 GB RAM and Windows 10 or higher correctly states minimum RAM and OS version, which are typical platform requirements.

3. Final Answer:

   Requires at least 4 GB RAM and Windows 10 or higher -> Option C

4. Quick Check:

   Hardware + OS specs = platform requirements [OK]

Hint: Look for hardware and OS specs in the options [OK]

Common Mistakes:

• Choosing UI or password rules as requirements
• Confusing device age with platform specs
• Ignoring minimum hardware needs

3. A software states: Minimum CPU: 2 GHz, RAM: 8 GB, OS: Linux Ubuntu 20.04+. Which computer below meets the requirements?

medium

A. CPU 1.8 GHz, RAM 16 GB, OS Linux Ubuntu 22.04

B. CPU 3.0 GHz, RAM 8 GB, OS Windows 10

C. CPU 2.5 GHz, RAM 4 GB, OS Linux Ubuntu 20.04

D. CPU 2.2 GHz, RAM 8 GB, OS Linux Ubuntu 20.04

Solution

1. Step 1: Check CPU speed and RAM for each option

   CPU 1.8 GHz, RAM 16 GB, OS Linux Ubuntu 22.04 has CPU below 2 GHz, so fails CPU requirement. CPU 2.5 GHz, RAM 4 GB, OS Linux Ubuntu 20.04 has RAM below 8 GB, so fails RAM. CPU 2.2 GHz, RAM 8 GB, OS Linux Ubuntu 20.04 meets CPU and RAM minimums. CPU 3.0 GHz, RAM 8 GB, OS Windows 10 has Windows OS, not Linux Ubuntu.

2. Step 2: Check OS version compatibility

   CPU 2.2 GHz, RAM 8 GB, OS Linux Ubuntu 20.04 uses Linux Ubuntu 20.04, which meets the minimum OS requirement.

3. Final Answer:

   CPU 2.2 GHz, RAM 8 GB, OS Linux Ubuntu 20.04 -> Option D

4. Quick Check:

   CPU≥2GHz, RAM≥8GB, OS=Ubuntu 20.04+ = CPU 2.2 GHz, RAM 8 GB, OS Linux Ubuntu 20.04 [OK]

Hint: Check CPU, RAM, then OS version in order [OK]

Common Mistakes:

• Ignoring CPU speed minimum
• Overlooking RAM requirement
• Not verifying OS type and version

4. A user tries to install software needing macOS 11+ but has macOS 10.15. What is the main issue?

medium

A. The hardware is too old

B. The operating system version is too low

C. The software needs more RAM

D. The software is incompatible with macOS

Solution

1. Step 1: Compare OS versions

   The software requires macOS version 11 or higher, but the user has 10.15, which is lower.

2. Step 2: Identify the compatibility problem

   Since the OS version is below the minimum, the software cannot run properly.

3. Final Answer:

   The operating system version is too low -> Option B

4. Quick Check:

   OS version < required version = The operating system version is too low [OK]

Hint: Check OS version meets minimum requirement [OK]

Common Mistakes:

• Assuming hardware is the problem
• Thinking RAM is insufficient without info
• Believing software is incompatible with macOS generally

5. You want to buy a laptop to run software requiring Intel i5 CPU, 16 GB RAM, Windows 11. Which laptop below is best suited?

hard

A. Intel i5 CPU, 16 GB RAM, Windows 11

B. Intel i5 CPU, 16 GB RAM, Windows 10

C. Intel i7 CPU, 8 GB RAM, Windows 11

D. Intel i3 CPU, 32 GB RAM, Windows 11

Solution

1. Step 1: Check CPU, RAM, and OS for each laptop

   Intel i7 CPU, 8 GB RAM, Windows 11 has enough CPU but insufficient RAM. Intel i5 CPU, 16 GB RAM, Windows 10 has correct CPU and RAM but OS is Windows 10, which is below requirement. Intel i5 CPU, 16 GB RAM, Windows 11 meets all requirements exactly. Intel i3 CPU, 32 GB RAM, Windows 11 has insufficient CPU despite high RAM and correct OS.

   Only Intel i5 CPU, 16 GB RAM, Windows 11 meets CPU, RAM, and OS requirements fully.

3. Final Answer:

   Intel i5 CPU, 16 GB RAM, Windows 11 -> Option A

4. Quick Check:

   CPU i5+, RAM 16GB, OS Win11 = Intel i5 CPU, 16 GB RAM, Windows 11 [OK]

Hint: Match all requirements exactly for best fit [OK]

Common Mistakes:

• Choosing higher CPU but ignoring RAM
• Ignoring OS version requirement
• Picking more RAM but weaker CPU
