Quick Questions

Shade in the A or B circle for each question.

1. Which best describes interoperability?

A Software that runs faster on a single device

B Software that can exchange data with other systems, devices and file formats

2. A student exports their marks as a CSV file so another program can open it. What is this an example of?

A Interoperability using a standard file format

B Interoperability using a proprietary format only one app can read

3. Which choice improves interoperability?

A Saving reports in a custom format only your app can open

B Saving reports as PDF so they open on any platform

4. An app works on Windows, macOS and a phone. Which UX characteristic does this support?

A Interoperability by working across platforms

B Affordance by showing a button looks clickable

5. True or false: An app that cannot import files from other software has high interoperability.

A False

B True

Answer Key

UX characteristic: interoperability

Section A: Quick Questions

B — Software that can exchange data with other systems, devices and file formats

A — Interoperability using a standard file format

B — Saving reports as PDF so they open on any platform

A — Interoperability by working across platforms

A — False

Section B: Match the Pairs

report.export("csv") → Saves data in a standard file format that spreadsheets and other software can open and use

GET /api/orders -> JSON → Exchanges data with other software by sending it in a common format that different systems can read

Working across platforms: the same saved file can be opened on Windows, macOS and mobile devices → save(report, "PDF")

Exchanging data with other software by importing a standard file format → import_data("students.csv")

save(report, "report.myapp") → Saving in a custom file format that only this software can open means other programs cannot read the data, so interoperability is poor. Use a standard format such as CSV or PDF.

if device == "Windows": run() else: error() → The software only runs on one platform and refuses to work on others. It should support multiple platforms such as Windows, macOS and mobile.

Section C: Definitions

interoperability — The ability of software to work with other systems, devices and file formats and exchange data with them, for example by using standard formats like CSV or PDF across platforms.

Section D: Fill in the Blanks

import csv

import json
text = json.dumps(record)

EXPORT report AS PDF
SHARE report WITH allUsers

IF fileFormat = "CSV" THEN
    IMPORT data
END IF

with open("data.csv", "w") as f:
    writer = csv.writer(f)
    writer.writerow(row)

Section E: Spot the Error

C — A custom format like .mydb can only be read by this one app, so it breaks interoperability. It should use a standard format such as 'grades.csv' that other software can open.

C — Other contact apps cannot read a private format. The contacts should be exported to a standard format such as vCard so they can be exchanged with other software.

A — The weather service sends its response as JSON, so it must be parsed as JSON. Reading it as CSV means the data is misread and cannot be exchanged correctly.

B — A non-standard encoding can garble characters when files move between platforms. The file should be read using the standard encoding UTF-8.

A — The program needs to bring data from another system into this one, so it must IMPORT the CSV file. EXPORT sends data out instead.
