Computer BNetwork B- Bcorrect Banswer-Two Bor Bmore Bcomputers Bconnected Bto Beach
Bother Bto Bshare Bresources B like:
•Folders Band Bfiles
•Software
•Hardware
B•Scanners
B•Printers
B•Webcams


Consider Ba Bnetwork Bmade Bup Bof Bthree Bcomputers B(Clients) Bconnected Bto Bone
Bcomputer Bcalled Ba BServer. BThe Bserver Bis Bconnected Bto Ba Bprinter Band Ba Bscanner
B(peripheral Bdevices) Benabling Ball Bthree Bclients Bto Buse Bthem. BAny Bdevice Bconnected
Bto Ba Bnetwork B is Bcalled Ba Bnode.


Network BAdvantages B- Bcorrect Banswer-Consider Ba Bbusiness Bthat Btries Bto Bsave Bmoney
Bby Bnot Bpurchasing Ba Bnetwork Bor Bnetwork Bsoftware. BAlthough Btheir Binitial Bcapital
Boutlay Bis Bsmaller Bthan Bthe Bsame Bsize Bbusiness Bthat Bchooses Bto Bbuy Ba Bnetwork,
Bthey Bsuffer Bfrom Bmany Bdisadvantages:


Economic BDisadvantages B- Bcorrect Banswer-With Bno Bnetwork, Beach Bcomputer Bwould
Bneed Btheir Bown Bperipheral Bdevices, Blike Bprinters. BWith Ba Bnetwork, Bonly Bone Bshared
Bprinter Bis Bneeded. BSoftware: BSoftware Bcan Bbe Bloaded Bon Ba Bserver Bfor Ball Bclients Bto

, Buse B whereas Ba Bbusiness Bwith Bstand-alone Bcomputers Bneeds Bsoftware Bloaded Bon
Bindividual Bboxes.


Collaboration B- Bcorrect Banswer-Networks Ballow Bbusinesses Bto Bshare Band Bcollaborate
Bon Bprojects.


Network BAdvantages B2 B- Bcorrect Banswer-Internet: BNetworks Ballow Bbusinesses Bto
Bshare Bthe BInternet Bwhereas Bstand-alone Bcomputers Bneed Btheir Bown Bindividual
BInternet Bconnection


Building Ba BComputer BNetwork B- Bcorrect Banswer-All Bnetworks Brequire Bfour Bbasic
Bcomponents


1.Network BInterface BController BCard B(NIC): BPlugged Binto Bthe Bmotherboard Bto
Binterface Band B connect Bwith Bother Bcomputers.


2.Protocol: BTCP/IP Bcontrols Bhow Bdata Band Binformation Bis Bshared Bbetween Bcomputers.

3.Cables: BCables Bconnect Bservers Bto Bclients Bwhich Bcan Bsometimes Bbe Breplaced
Bthrough Bwireless Bconnections.


4.Hub: BTypically Bthe Bcentral Blocation Bof Ba Bnetwork B(server) Bthat Bserves Bto Brun Bthe
Bnetwork Bsmoothly


Network BProtocols B- Bcorrect Banswer-Provides Ba Bcommon Blanguage Band Brules Bfor
Bcommunication Bbetween Bcomputers. BA Bprotocol B is Ba Bconvention Bor Bstandard Bthat
Bcontrols Bor Ballows Bcommunication Band Bdata Btransfer Bbetween Btwo Bcomputers.


Transmission BControl BProtocol B/ BInternet BProtocol B(TCP/IP): B- Bcorrect Banswer-When
Bsending Ba Bfile Bfrom Bone Bcomputer Bto Banother, Bthe Bfile Bis B broken Bdown Binto
Bsmaller Bfiles Bcalled B"packets". BThe Bpackets Barrive Bat Bthe Breceiving Bcomputer Band
Bmust Bbe Breassembled Bcorrectly Bto Bguarantee Bthe Breceiving Bcomputer Bgets Ba Bfile Bthat
Bwill Bwork B(not Bcorrupted).


User BDatagram BPackets: B- Bcorrect Banswer-Break Blarge Bfiles Binto Bpackets, Bbut Bunlike
BTCP/IP, Ballows Ba Buser Bto Buse Bthe Bincoming Bfile Beven Bif Bsome Bpackets Bdo Bnot
Bmake Bit.


Would BYouTube.com Bexist Bwithout BUDP? B- Bcorrect Banswer-TP B- Bshow BTCP/IP Band
BUDP Bjoke B- Bsending Band Breceiving Band B.....


Network BOperating BSystems B- Bcorrect Banswer-A BNetwork BOperating BSystem B(NOS)
Bis B similar Bto Ba Bstand-alone Bplatform Bbut Bresponsible Bfor Bmuch Bmore:


•Automatic Bhardware Bdetection. BThe BNOS Brecognizes Bit Bwhen Bit Bbecomes Bpart Bof
Bthe Bnetwork.


•Supports Bmulti-processing Bwhich Ballows Bseveral Bprocesses Bto Boccur Bat Bone Btime. B

•Recognizes Bwho Bis Busing Bthe Bnetwork.
