Learning Objectives
describe information systems hardware;
identify the primary components of a computer and the functions they perform; and
explain the effect of the commoditization of the personal computer.
Hardware
desktop computers
laptop computers
mobile phones
tablet computers
e-readers
storage devices, such as flash drives
input devices, such as keyboards, mice, and scanners
output devices such as printers and speakers.
Digital Devices
Processes electronic signals into discrete values
Binary values (1=on, 0= off)
Each value (1 or 0) is a bit
Eight bits = 1 byte
PCs
1st PCs could only process 8 bits of data at once
Today PCs can process 64-bits of data at once
Read Sidebar: Understanding Binary
Tour of a PC
Processing data: The CPU
CPU = Central Processing Unit
The brains of the device
Read: Sidebar: Moore’s Law and Huang’s Law
The number of integrated circuits on a chip doubles every two years
VS
Speeds of GPUs are increasing faster.
Hardware Components
Motherboard
the main circuit board on the computer
Other components (CPU, memory, and storage) connect into the motherboard, contain integrated components like network cards, video, etc.., contains the bus of the PC (which determines the computer’s speed)
RAM
Working Memory (Random Access Memory)
Hard Disk
Used for longer term storage
Solid State Drives
Removable Media
Connections, Input and Output
Network Connections- digital network
Input and Output
Bluetooth – a method to connect via wireless technology
Input Devices
Scanners
Microphones
Keyboard/Mouse
Webcams
Output Devices
Display/ Monitor
Speakers
Printer
Sidebar: Which Hardware Components Contribute….
Many elements contribute to the speed of your computer
Hardware = increase by giving electrons less distance to travel in completing a circuit
Multi-core processors (CPUs)
Other Computing Devices
Portable Computers
Smartphones
Tablet Computers
Integrated Computing and Internet of Things (IoT)
