Chapter-7 Data Entry and Keyboarding Skills — Important Questions & Answers (FAQ)

Frequently asked questions from CBSE(NCERT) Grade 9 INFORMATION TECHNOLOGY — Chapter-7 Data Entry and Keyboarding Skills, with answers and explanations. These are sample questions; the exam has its own separate question set.

What is the primary purpose of ergonomics in the context of keyboarding?

A. To increase typing speed by 100 WPM
B. To prevent physical strain and injury while working at a computer ✓
C. To reduce the cost of computer equipment
D. To make the keyboard more aesthetically pleasing

Answer: B. To prevent physical strain and injury while working at a computer
Ergonomics focuses on designing workspaces and equipment to prevent strain, injury, and promote comfort during prolonged computer use.

Which keys are considered 'guide keys' or 'home row keys' on a QWERTY keyboard?

A. Q, W, E, R, T, Y
B. A, S, D, F for left hand and J, K, L, ; for right hand ✓
C. Z, X, C, V, B, N
D. 1, 2, 3, 4, 5, 6

Answer: B. A, S, D, F for left hand and J, K, L, ; for right hand
The home row keys are the starting position for touch typing. Fingers rest on A, S, D, F (left hand) and J, K, L, ; (right hand), with small bumps on F and J for positioning.

At what height should the keyboard be positioned for optimal ergonomics?

A. Above the elbows to stretch the arms
B. At elbow height or slightly below, allowing forearms to be parallel to the desk ✓
C. As low as possible to reduce arm movement
D. At shoulder height for better visibility

Answer: B. At elbow height or slightly below, allowing forearms to be parallel to the desk
The keyboard should be positioned at or slightly below elbow height, allowing the forearms to be parallel to the desk surface, which minimizes wrist and shoulder strain.

Analyze this scenario: A typist has a WPM of 60 but only 75% accuracy. Compare this to a typist with 40 WPM and 98% accuracy. Which typist is more suitable for professional data entry work?

A. The 60 WPM typist because speed is more important
B. The 40 WPM typist because accuracy is critical in data entry ✓
C. Both are equally suitable
D. Neither is suitable for professional work

Answer: B. The 40 WPM typist because accuracy is critical in data entry
In professional data entry, accuracy is more critical than speed because errors can lead to data corruption and financial losses. A 98% accuracy rate is significantly better than 75%, even if the speed is slower.

In competitive typing exams, which metric is typically considered MORE important by judges: raw WPM or net WPM (accuracy-adjusted)?

A. Raw WPM, because judges value speed above all else
B. Net WPM, because it reflects true typing proficiency by accounting for accuracy ✓
C. Both are equally weighted in all competitions
D. Neither metric is used in competitive typing

Answer: B. Net WPM, because it reflects true typing proficiency by accounting for accuracy
In most professional and competitive typing assessments, net WPM is preferred because it provides a more accurate measure of true typing skill by subtracting errors, rewarding both speed and accuracy rather than penalizing mistakes.
