MCSE

MCSE (Microsoft Certified System Engineer)

Lecture # 1 Hardware Requirement for a Computer Network:

  •      Computers
  •      NIC Card or LAN Cards or Ethernet Card
  •       Wires (UTP Cat5)
  •       RJ-45 Connectors
  •       HUB / Switch

NIC CARD:

  • NIC Card having RJ-45 Port.
  • Slot is called PCI.
  • NIC Card having a chip called NPU (Network Processing Unit).
  • NPU is responsible for Sending / Receiving data.
  • NPU has further two chips inside.

RX(Receive data from wires)

TX(Transmit data to motherboard)

  • RJ-45 having 8 pins.
  • 1, 2 wires for Transmit
  • 3, 6 wires for Receive
  • Remaining 4 wires are for future use.
  • 1 Gbps or 10 Gbps use all 8 wires for communication.

TYPES OF NIC CARD:

  • Ethernet           (Common used)
  •  Token Ring        (Old Technology)
  •  FDDI              (Costly)
  • ATM              (Very Costly)
  • Wireless           (Less Speed, No Security)

Ethernet:

  • Ethernet Card (100 Mbps)
  • Used Ethernet Card having Cost (Rs. 50)
  • Switch Speed is 100 Mbps
  • 1 Gbps Ethernet Card (Rs. 1200)
  • 100 Mbps Switch (Rs. 1200-1400)
  • Normally used in Computer Labs.

Fiber Optic:

  • Fiber Card
  • Fiber Cable (Rs. 3000-4000)
  • Very Costly Network
  • Very Fast Communication
  • Processing Speed is very fast
  • Media converters are used between Fiber network and other network.
  • Normally used in Server Rooms
  • Basically designed for Audio and Video Conferencing.
  • Very Expensive Technology.
  • ATM Cards and ATM Switches are used.
  • Normally used as ISP back bone, Manager Rooms (etc)
