What Are Peripheral Devices of a Computer? - Definition, Examples & Types

1. What Are Peripheral Devices of a Computer? - Definition, Examples & Types

A peripheral device connects to a computer system to add functionality. Examples are a mouse, keyboard, monitor, printer and scanner. Learn about the different types of peripheral devices and how they allow you to do more with your computer.

I/O Control Methods: Types & Explanation

2. I/O Control Methods: Types & Explanation

In this lesson you will learn about the basics of input and output. You will also learn about the different types of input/output (I/O) control methods within a computer, mainframe and server, and how they work within your computer systems. Finally, you will learn about process order when transferring data back and forth between I/O devices and the computer.

System Bus in Computers: Definition & Concept

3. System Bus in Computers: Definition & Concept

A computer bus transfers data between components of a computer system. In this lesson, we'll talk about how a system bus works, what it's useful for, and what aspects of it make for a good overall performance of a computer.

Bus Timing Diagrams: Definition & Interpretation

4. Bus Timing Diagrams: Definition & Interpretation

In this lesson, you will learn about bus timing diagrams and how to use a bus timing diagram to describe the flow of data in a system bus. Examples of a system bus and a memory read/write operation are detailed.

External and Internal Storage Devices: Optical, Magnetic & Semiconductor Storage

5. External and Internal Storage Devices: Optical, Magnetic & Semiconductor Storage

Let's explore the capacity of internal and external storage devices. We'll learn how optical, magnetic and semiconductor storage works, as well as identify some examples of storage devices.

What is Flash Memory for Data Storage?

6. What is Flash Memory for Data Storage?

Flash memory is a common data storage component in consumer electronics. In this lesson we will review the basic operation of this form of memory and compare its features with older data storage technology.

RAID Arrays & Data Redundancy

7. RAID Arrays & Data Redundancy

RAID uses multiple hard disk drives to improve the reliability and performance of data storage. Learn how RAID provides data redundancy to protect against hard disk drive failures.

Real-World Examples of Bus Architectures

8. Real-World Examples of Bus Architectures

In this lesson, we will explore two real-world examples of bus architectures: USB and SCSI. We will provide an overview of the basics of the architecture including timing diagrams.

Amdahl's Law: Definition, Formula & Examples

9. Amdahl's Law: Definition, Formula & Examples

If you want to improve a system which is composed of different components, how would you decide which component to choose to get the best overall improvement? Amdahl's law gives you the means to make this decision.
