Types of Network
- 1. TYPES OF NETWORKS UGC/NTA & OTHER EXAMS
- 2. 1. PERSONAL AREA NETWORK (PAN) • PAN IS MADE UP OF A WIRELESS MODEM, A COMPUTER OR TWO, PHONES, PRINTERS, TABLETS, ETC., AND REVOLVES AROUND ONE PERSON IN ONE BUILDING.
- 3. 2. LOCAL AREA NETWORK (LAN) • LAN CONNECT GROUPS OF COMPUTERS AND LOW-VOLTAGE DEVICES TOGETHER ACROSS SHORT DISTANCES (WITHIN A BUILDING OR BETWEEN A GROUP OF TWO OR THREE BUILDINGS IN CLOSE PROXIMITY TO EACH OTHER) TO SHARE INFORMATION AND RESOURCES.
- 4. 3. WIRELESS LOCAL AREA NETWORK (WLAN) • FUNCTIONING LIKE A LAN, WLANS MAKE USE OF WIRELESS NETWORK TECHNOLOGY SUCH AS WI-FI. TYPICALLY SEEN IN THE SAME TYPES OF APPLICATIONS AS LANS, THESE TYPES OF NETWORKS DON’T REQUIRE THAT DEVICES RELY ON PHYSICAL CABLES TO CONNECT TO THE NETWORK.
- 5. 4. CAMPUS AREA NETWORK (CAN) • LARGER THAN LANS, BUT SMALLER THAN METROPOLITAN AREA NETWORKS (MANS,) THESE TYPES OF NETWORKS ARE TYPICALLY SEEN IN UNIVERSITIES, SCHOOL OR SMALL BUSINESSES. THEY CAN BE SPREAD ACROSS SEVERAL BUILDINGS THAT ARE FAIRLY CLOSE TO EACH OTHER SO USERS CAN SHARE RESOURCES.
- 6. 5. METROPOLITAN AREA NETWORK (MAN) • THESE TYPES OF NETWORKS ARE LARGER THAN LANS BUT SMALLER THAN WANS AND INCORPORATE ELEMENTS FROM BOTH TYPES OF NETWORKS.
- 7. 6. WIDE AREA NETWORK (WAN) • WAN CONNECTS COMPUTERS TOGETHER ACROSS LONGER PHYSICAL DISTANCES. THIS ALLOWS COMPUTERS AND LOW-VOLTAGE DEVICES TO BE REMOTELY CONNECTED TO EACH OTHER OVER ONE LARGE NETWORK TO COMMUNICATE EVEN WHEN THEY’RE MILES APART. • THE INTERNET IS THE MOST BASIC EXAMPLE OF A WAN, CONNECTING ALL COMPUTERS TOGETHER AROUND THE WORLD.
- 8. 7. STORAGE-AREA NETWORK (SAN) • AS A DEDICATED HIGH-SPEED NETWORK THAT CONNECTS SHARED POOLS OF STORAGE DEVICES TO SEVERAL SERVERS, THESE TYPES OF NETWORKS DON’T RELY ON A LAN OR WAN, SUCH AS CONVERGED, VIRTUAL AND UNIFIED SANS.
- 9. 8. SYSTEM-AREA NETWORK (SAN) • IT IS USED TO EXPLAIN A RELATIVELY LOCAL NETWORK THAT IS DESIGNED TO PROVIDE HIGH-SPEED CONNECTION IN SERVER-TO-SERVER APPLICATIONS. THE COMPUTERS CONNECTED ON A SAN OPERATE AS A SINGLE SYSTEM AT VERY HIGH SPEEDS.
- 10. 9. PASSIVE OPTICAL LOCAL AREA NETWORK (POLAN) • AS AN ALTERNATIVE TO TRADITIONAL SWITCH-BASED ETHERNET LANS, POLAN TECHNOLOGY CAN BE INTEGRATED INTO STRUCTURED CABLING TO OVERCOME CONCERNS ABOUT SUPPORTING TRADITIONAL ETHERNET PROTOCOLS AND NETWORK APPLICATIONS SUCH AS POE (POWER OVER ETHERNET).
- 11. 10. ENTERPRISE PRIVATE NETWORK (EPN) • THESE TYPES OF NETWORKS ARE BUILT AND OWNED BY BUSINESSES THAT WANT TO SECURELY CONNECT ITS VARIOUS LOCATIONS TO SHARE COMPUTER RESOURCES.
- 12. 11. VIRTUAL PRIVATE NETWORK (VPN) • BY EXTENDING A PRIVATE NETWORK ACROSS THE INTERNET, A VPN LETS ITS USERS SEND AND RECEIVE DATA AS IF THEIR DEVICES WERE CONNECTED TO THE PRIVATE NETWORK – EVEN IF THEY’RE NOT. THROUGH A VIRTUAL POINT-TO- POINT CONNECTION, USERS CAN ACCESS A PRIVATE NETWORK REMOTELY.
