EDPT (Electronic Data Processing Test) 3 — Questions and Answers
Question 1: Which of the following best describes a computer network topology where every device connects to a central hub?
- Bus topology
- Ring topology
- Star topology (Correct answer)
- Mesh topology
Correct answer: Star topology
In a star topology, all devices connect to a central switch or hub; if the hub fails the entire network goes down.
Question 2: What does the acronym CPU stand for?
- Central Processing Unit (Correct answer)
- Core Programming Utility
- Computer Power Unit
- Central Program Uploader
Correct answer: Central Processing Unit
CPU stands for Central Processing Unit, the primary component that executes instructions in a computer.
Question 3: Which storage device uses magnetic platters to store data and retains data without power?
- RAM
- Cache memory
- Hard disk drive (Correct answer)
- CPU register
Correct answer: Hard disk drive
A hard disk drive (HDD) uses spinning magnetic platters to store data non-volatilely, meaning it retains data when powered off.
Question 4: In binary arithmetic, what is 1011 + 0101?
- 1110
- 10000 (Correct answer)
- 1111
- 10001
Correct answer: 10000
1011 (11 decimal) + 0101 (5 decimal) = 10000 (16 decimal); the carry propagates to produce a 5-bit result.
Question 5: Which protocol is used to assign IP addresses automatically to devices on a network?
- FTP
- DNS
- DHCP (Correct answer)
- HTTP
Correct answer: DHCP
DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses and other network configuration parameters to devices.
Question 6: In a database, a table row is also referred to as a:
- Field
- Attribute
- Record (Correct answer)
- Schema
Correct answer: Record
A row in a database table is called a record; it represents a single, complete data entry across all columns.
Question 7: Which of the following is an example of output hardware?
- Keyboard
- Scanner
- Monitor (Correct answer)
- Microphone
