• what are the qualities of a Hybrid laptop?

  • It can rotate 360 degrees
  • A 2-in-1 detachable system that the keyboard and display to be completely separated
• Advantages of a Hybrid laptop?

  • you have less to pack when travelling, because you don't have to pack a laptop and a table
  • the table has a touch screen, which the traditional laptop does not have
• Disadvantages of a Hybrid laptop

  • Has a shorter battery life
  • Often doesn't contain built-in communications
• What does a Non-portable computer consist of?

  • system unit
  • Monitor
  • Mouse
  • Keyboard
• Name three types of Non-portable computers

  • Desktop computer
  • High-end desktop _ has high specification in term of processing power
  • Server _ provides resources and services to all the computers linked in a network
• A all-in-one Non-portable computer does not have have a System unit like a Non-portable computer, Where is the system unit?


  System Unit is built into the monitor
• Virtual Reality (VR)


  This refers to using technology to create a simulation of a 3D-environment that can be interacted with by a person in a seeming real or physical way. This is achieved by using equipment, such as helmets with screens and gloves fitted with sensors
• Advantages of Virtual Reality

  • Explores places
  • Virtual reality makes education more easily and comfortable
  • Train employees (i.e. Pilots being trained) without causing damage or injuries
  • Conferencing (digital meetings)
  • Convenience (cut costs on travelling)
  • Helps students to learn faster and remember longer
• Disadvantages of Virtual Reality

  • Can be expensive BECAUSE OF the special equipment and software needed for editing
  • VR-glasses and a 360 degree video camera is also needed if you want to create your own VR-environment
  • Availability of such hardware
  • Physical effect: motion sickness, balance is affected by changes in the inner ear
• Where can Virtual Reality (VR) be used?

  • To train employees (i.e. pilots)
  • Conferences
  • Games - Nintendo, iGlasses
  • Drowns
  • Media - marketing campaign
  • Education and training
  • Medical personnel are able to train VR to deal with a wider variety of injuries
• What is drown technology?

  A drone, an unmanned aircraft. Essentially , a drone is a flying robot that can be remotely controlled or fly autonomously through software-controlled flight plans in their embedded systems, working in conjunction with on-board sensors and GPS. They are widely used in agriculture , photo , photography , game ranging , parcel deliveries, etc.
• Wearable devices and technologies

  Wearable technologies such as electronic mobile devices worn as accessories or part of clothing , e.g. smartwatches or fitness/health tracker , smart glasses , continuously generating data from various environment and communicating with other devices/PC/networks
• What type of computer will be suitable for power users ?

  Computers with high-speed specifications
• Why must power users use computers with high-speed specifications ?

  The software they use require fast processors , large memory , large storage , etc.
• Difference between a client computer, peer-computer, server computer.

  • CLIENT COMPUTER: computers connected to the server , that use network resources like a share d printer and data
  • PEER-COMPUTER: computer that use and provide network resources
  • SERVER COMPUTER: other computers in the network are connected to the server in the order to use the resources of the server , the server controls the resources , computer that provides network services
