WEEK 5 (HARDWARE PERIPHERALS) Flashcards
What are the primary differences between alphanumeric and special-function keys on a keyboard?
Alphanumeric keys are used to input letters, numbers, and symbols. Special-function keys have predefined specific purposes, such as PgUp, PgDn, Enter, and Shift.
Write a step-by-step method to use the Ctrl key in combination with other keys to perform three distinct actions in a word processor.
Ctrl + C: Copies the selected text.
Ctrl + V: Pastes the copied text.
Ctrl + S: Saves the document.
Connect a barcode reader to a computer and explain how the input is processed to display the corresponding product information.
The barcode reader scans the barcode, decodes the data using its software, and transmits the information to the computer, which is then displayed in the relevant application (e.g., inventory management system).
Compare the energy efficiency and display quality of LED and CRT monitors.
LED monitors are more energy-efficient and produce brighter, sharper images compared to CRT monitors, which are bulkier and consume more power.
Connect a printer to a computer, print a test page, and list the steps to troubleshoot if the print job fails.
Check printer connection and power.
Ensure the correct driver is installed.
Verify printer settings and ink/toner levels.
Restart the printer and clear the print queue.
What are the primary differences between RAM and SSD in terms of functionality and performance?
RAM is a volatile memory used for temporary data storage while programs are running; it has faster access times.
SSD is a non-volatile memory used for permanent data storage with slower access times compared to RAM.
Using a USB flash drive, transfer a file from one computer to another and calculate the transfer time if the file size is 2GB and the USB speed is 60MB/s.
Transfer time = File size / Speed =

Explain the dual functionality of a touchscreen device as both an input and an output device.
A touchscreen displays information (output) and accepts user interactions like touches or gestures to send commands to the system (input).
Create a diagram or flowchart showing how a modem facilitates data exchange between a computer and the internet.
The modem modulates digital data from the computer to analog for transmission via phone lines and demodulates incoming analog signals back to digital.
Why are magnetic tape drives considered more suitable for large data backups despite their slower access times?
Magnetic tapes are cost-effective, have large storage capacities, and are reliable for archival purposes, despite slow sequential access.
Insert an SD card into a computer, format it, and store a document. Document each step you take.
Insert the SD card into the slot.
Open File Explorer and locate the card.
Right-click on the card and select “Format”.
Choose file system type (e.g., FAT32) and click “Start”.
After formatting, drag and drop the document onto the card.
Discuss the advantages of using Network Attached Storage (NAS) over traditional external hard drives for businesses.
NAS allows multiple users to access shared data over a network, offers scalability, and supports RAID configurations for data redundancy.
Set up a cloud storage account (e.g., Google Drive), upload a file, and share it with another user. Document the steps and challenges faced.
Create a Google Drive account.
Upload the file using the “New” -> “File Upload” option.
Right-click the file, select “Share”, and enter the recipient’s email.
Ensure the sharing permissions are set correctly.
