Digital Systems Digital System - Consist of Hardware and Software - Store , process and transmit data in a digital format Hardware Definition Any part of the digital system which you can physically touch , pick up or move Hardware Devices' Hardware Component Each Hardware Component consists of : 1. Circuit Board 2. Memory Chips 3. Electronic Wiring Examples : Monitors keyboards - Hard drives - - Mouses - CPU's - RAM4 Software Definition Instructions used to manipulate data or to request other hardware components to perform a task Software a Central Processing Unit (CPU) Software s Cpu Software instructions are read by CPU , CPU then Sends electrical signals to the hardware to perform a task Examples ofSoftware : Word Processors - · Smart phone apps Spreadsheets - Operating Systems - Anti - virus - Film Editing - Presentation Software Applications -Created using programming language - E Word Powerpoint Excel g etc.... , ,  When - users click to open software application , the instruction are sont to CPU Digital System Devices Detention - Contains of hardware & Software range components Digital designed to store process data binary digital form - system are , a communicate in or Example : Desktop - Laptop - - Tablet Smart-Phone Binary Detention All digital devices use binary - Number System Binary number of two digits I - system consist - O and * Electronic circuits transitors in hardware consist of · If signal is a 1 transitor is turned on · It signal is a 0 transitor is turned off * When data file ofIs DO's is stored in a , the file size represents the number stored in a file · A single 1 or O is known as a bit (b) · A collection of 8 bits is known as a Byte (B) Most 2 #) need " characters (e g.. 3.. k , , one byte of storage File Sizes frie sizes Often represented using kilobytes Megabytes. or gigabytes 1024 · bytes = Kilobyte (kB) 1024 kilobyte Megabyte (MB) · : · 1024 Megabyte : Gigabyte (GB) * The bits (Osa 1s) larger the file size , the more used to represent data in the file Hardware - Input & Output Hardware Detention Any physical part of the digital system which you can physically touch. Pick up , or more Hardware devices contain : - Circuit Board Memory Chips Electronic Wiring - * Electronic Signals (Software instructions) the are sent through wiring to instruct the hardware to perform a task Can be grouped into : Input Devices · Output Devices - - System Unit Devices Input Devices Definition Input device that sends data · to computer Allowing · user to interactWith a Control the computer Input device human binary signals that · converts understandable data and instruction) into are understood by the computer Examples 1. Microphone 2 Mouse. 3. Keyboard. Webcam 4 5. Joystick Output Devices Detention Act interface between humans - as s computers - Hardware device that receives data from CPU and converts it to human understandable information - Can be in text , images , music , Voice Messages etc , Examples : 1. Monitors. 7 Projectors. 3 Headphones 4. Speakers 5. Printers Both in put & Output Example : Touch Screen System Unit System Unit Refers to any component within the desktop tower Components include : I. Motherboard. Central 2 (CPU) Processing Unit 3. Hard Disk Drive (HDD) 4. Random Acess Memory (RAM). 5 Read Only Memory (ROM). Ports 6 Motherboard Definition - Base that contains other system all Unit components Contains - electrical circuits connected to a series of slots and ports Central (CPU) Processing Unit Deterrition Brain digital system - of the Steps performed by
