Input and Output Devices

5) Define input and output device

An input device is a peripheral used to provide data and control signals to an information processing system.

An output device is any piece of computer hardware used to communicate the results of data processing.

RAM vs. ROM

6) What is the difference between ROM and RAM?

ROM: Access to memory information is lost when the computer is turned off.

RAM: Contains instructions and routines for CPU operations.

Flash Memory Q&A

1. What is Flash Memory?

   Flash memory is a type of memory that can be electronically erased and reprogrammed.

2. RAM vs. Flash Memory

   RAM is volatile, while flash memory is non-volatile and retains information when the power is turned off.

3. Multi-Level Cell Technology

   Devices using multi-level cell technology can store more than one bit per cell.

4. Flash Memory vs. External Hard Drives

   USB flash drives have less capacity than external hard drives and are easier to transport.

5. Advantage of U3 Technology

   U3 technology allows running portable programs on flash drives.

6. Flash Memory Card Capacity

   Storage varies between 8 MB to several gigabytes.

Hard Drive and Data Storage

1. Principal Function of Particles

   Storing data on a disk or tape.

2. What are Platters?

   Magnetic storage devices storing data can be disk or tape.

3. Characteristics of OS

   • Create disk partitions
   • Allows you to install more than one operating system on the partitions. If there are problems with one, another operating system can be installed again.

4. System Clock vs. Transfer Rate

   • System clock measures and synchronizes data flow, partly determining processor speed.
   • Transfer Rate: The speed required to transmit data from a disk to the CPU.

5. Define Imperative with Examples

   Imperative verbs give an instruction. We are asking someone to do something.

6. How to Protect Your Hard Drive

   • Keep the PC at a suitable temperature, avoiding sudden changes from cold to hot or hot to cold.
   • Avoid the presence of magnetic sources near the PC: appliances generate magnetic fields.
   • Do not expose the equipment to vibrations or sudden movements.

7. Hard Drive Components

   The image is of a hard drive showing important parts:
   • Head actuator: Positions the read/write heads on the correct track on the disk surface.
   • Head arms: Thin pieces of metal carrying information and the read head actuator.
   • Disk platter: A circular disc where magnetic data is stored.
   • Coated metal chassis: Protects the hard drive.
