Computer hardware and networking components

  1. 1. Computer Hardware And Networking
  2. 2. Computer Hardware The computer Hardware refers to the physical components of computer. In deed it is a machine which can perform various tasks for us. Hardware like Motherboard, Disk Drives, Daughter Board (LAN card, sound card, VGI card, etc ).
  3. 3. Computer HardwareComputer Hardware ComponentsComponents
  4. 4. Mother board- It is the main printed circuit board (PCB), It hold many of the crucial electronic components of the system.
  5. 5. Central Processing UnitCentral Processing Unit The microprocessor consists of three sections: 1.Arithmetic Logic Unit 2.Registers 3.Control Unit
  6. 6. MEMORY SLOTMEMORY SLOT There are 4 shortThere are 4 short slots for SIMMslots for SIMM memory.memory. This board hasThis board has two long slots fortwo long slots for a new kind ofa new kind of memory calledmemory called DIMM DRAMDIMM DRAM..
  7. 7. RAM-Random Access Memory It is a storage device that Temporary stores data while the computer is turned on.
  8. 8. HDD- Hard Disk Drive The main storage area in the computer where the operating system is stored along with other applications.

CD-ROMDVDs. CD-ROM drives cannot readdrives cannot read DVDs.DVDs.
  10. 10. Computer Networking
  11. 11. Networking Hardware The devices which are used to connect two or more computers placed anywhere can be termed as Hardware for Networking.
  12. 12. Networking devices There are many networking devices- 1.LAN cards 2.Repeaters 3.HUB 4.Switches 5.Router 6.Networking Hardware.
  13. 13. 1.LAN Card A LAN (local area network) card connects a computer to a network, whether local of foreign. It is connected to the computer mother board via serial port.  Now a days these are by default connected to the Mother Board.
  14. 14. 2.Repeaters • Connectivity devices that regenerate and amplify an analog or digital signal so as to transfer it to far places.
  15. 15. 3.Hubs Multiport repeater containing multiple ports to interconnect multiple devices. They reduces the strength of signal for every connected port. Due to this they are not used now a days.
  16. 16. 4.Switches Subdivide a network into Smaller logical pieces. They can also amplify the signal.
  17. 17. 5.Routers Multiport connectivity device. There main purpose is to connect two or more network connection having different Network IDs.
  18. 18. 6.Networking hardware a. Cables and connectors b. Networking tools.
  19. 19. a. Cables and connectors Coaxial cables - These cables are used to carry electrical signals b/w two or more computers. UTP - Unshielded Twisted Pair cables. It is a set of three or four pair of wires, with each pair twisted around each other to prevent electromagnetic interference.
  20. 20. Fiber optical cable Fiber optic cable carries light signal. These are used to carry data at distant places, which cannot be done by coaxial cables or UTP. They are more secured, less loss in signal strength.
  21. 21. Connectors RJ45 – This connector is used to connect the twisted pair cables with the networking devices. BNC- it is commonly used in base 10 Ethernet network, it is used to end the magnetic signal within the cable which carries info.
  22. 22. Networking Tools Crimping tool - this tool is designed for the connections of the UTP cables with the connectors by cutting, stripping, deforming. Crimping was developed as a high-quality, low cost replacement for soldering process.
  23. 23. Krone tool – A Punch Down tool used by the telecommunication and network technicians. It is used for inserting wires in insulation- displacement connector.
  24. 24. Summary - Together with the combination of hardware and networking the existing form of networking is available, which is fast, compact, easy to use and secured.
