type of computer where the parts and the processor are all together in a single unit

Main Features: Have several CPU's, very fast processor speed, can support multiple operating system, large storage capacity, huge internal memories,etc.

Advantages:easy to use for monitoring fitness and health, more convenient

Disadvantages: can be uncomfortable to use, have unattractive design

Advantages fast to switch on,, fully portable, simple touch-screen technology, don't generate heat, longer battery life,

Disadvantages: limited memory/storage, support less type of file formats,

Advantages: cheaper, better specification for a given price, less power consumption, less likelyhood of damage, more stable internet connection

Disadvantages: not portable, clutters up desk space

Advantages: portable, no trailing wires, can take full advantage of Wi-Fi, can link to any multimedia system

Disadvantages: easier to steal, limited battery life, touchpads can be awkward to use

making a message impossible to understand for unknown users.

artificial envoronment created by a software.

makes use of:

System Software

data goggles

sensor suits

data gloves / helmets

Compiler - a program written in high-level language ( HLL ) into machine code ( code that is understood by the computer ) so that it can be directly used by a computer to perform a required task.

Linkers - a computer program that takes one or more object tiles produced by a computer and combines them into a single program that can be run on a computer .

Device Driver - enables one or more hardware devices to communicate with the computer's operating system.

Operating System (OS) - essentially a software running in the background of a computer system.

Untilities - softer that has been designed to carry out specific tasks on a comperier.

robots are used mostly in manufacturing industries.

Random Access Memory (RAM)

Central Processing Unit (CPU)

Read-only Memory (ROM)

Store information that need to be permanant like the configuration data, it's non-volatile

Where data is temporarily stored when running an application, it's volatile

Computer's main internal storage, stores application software,disk operating systems and files

Interprets and executes commands from the hardware and software

low - vision enhancement systems

night vision enhancement

use video technology to produce images inside the headset in front of people's eyes.

makes an image still be visible in darkness.

language translator that uses the help of a software.

Definition: physical components that make up a computer system.

Definition: programs that control the computer system

Impact: More reliable security systems

Impact: clearer image than original

Impact: allows safer working environment, reduce manufacturing costs

Impact: allow pre-view of designs, better entertainment experience, allow the use if simulations

Impact: help learning of new language, easier communication with others

Impact: safer data transfer security

Definition: special software that enables computer systems to function and to allow users to communicate with computer systems

General Tasks

Dealing with computer errors

Maintaining security

Supervising application programs

Maintain a computer log that details the computer usage

Control the operation of the input, output, and backing storage devices

Allow communication between user and computer system (user Interface)

types

Graphical User Interface (GUI)

Disadvantages

Command Line Interface (CLI)

A visual way of interacting with a computer using items such as windows, icons, and menus, used by most modern operating systems

Advantages

Users are required to type in commands to interact with the computer

Advantages

  1. the user is in direct communication with the computer.
  1. it is possible to alter computer configuration settings.

Disadvantages

  1. The user is limited to the icons provided on the screen.

1.It uses up considerably more computer memory than a CU interface.

  1. The user is limited to the icons provided on the screen

2.It is more user friendly: icons are used to represent applications.

1.The user doesn't need to learn any commands

  1. the user needs to learn a number of commands to carry out basic operations.
