Anything which fllws an i.e. details what must be taught as part f that area f cntent. Anything which fllws an e.g. is illustrative, it shuld be nted that where e.g. is used, learners must knw and be able t apply relevant examples t their wrk thugh these d nt need t be the same nes specified in the unit cntent. Learners will need t lk at the fllwing areas LO1 Knw the current use f cmputer netwrks cmmunicatin in cmputer netwrks culd be: individual (e.g. Blgs, emails, ) resurces: rganisatinal: (e.g. email, wikis, file strage, data centres) cllabrative (e.g. scial netwrking, webinars) live (e.g. vide, interactive web cnferencing, desktp sharing, Cmmunicatin in terms f sharing f electrnic dcuments between grup members n prject wrk).

DELIVERY GUIDANCE T deliver this unit the tutr culd fllw the teaching cntent rder althugh this must be with a fcus n learner participatin and discussin based n experiences. Knw the current use f cmputer netwrks This culd be enhanced by the use f visits r talks with IT netwrk staff. Learners t be encuraged t discuss their wn experiences with using netwrks and t research the many different ways f cmmunicatin, the ways resurces are managed and any issues which cme with using a netwrk. Learners t be encuraged t research and describe the Data Prtectin Act as it applies t shared data. They will need t lk at an rganisatin and lk at the flw f cmmunicatin, hw it flws in and ut f an rganisatin i.e. hw is the infrmatin prvided t all the users in the rganisatin (email, ntice bards, meetings, blgs, virtual envirnments, lgs, website, etc, des it always wrk? What are the cnstraints such as security, speed?). They shuld be encuraged t explre cmmunicatin methds reprting and sharing their findings with the grup and discussing the benefits and risks. Knw the features and services f lcal and wide area netwrk technlgies Learners t be intrduced t the different tplgies f netwrking. Learners shuld be encuraged t create wall displays, psters r leaflets abut the tplgies, their uses and visual representatins f them. Learners t lk at the different types f netwrks as in peer t peer and client server, making this as practical as pssible and invlving the identificatin f the netwrking cmpnents will add t the mtivatin and interest and will help with an understanding f hw the netwrk hardware cmpnents are cnnected. They will need t investigate the different uses f the different netwrks and their suitability fr different users. Learners will need t lk at addressing and hw this is incrprated int the netwrk, they culd be given a netwrk in which they need t either find IP and MAC addresses r t put the IP addresses nt the machines and find the MAC addresses f the cmputers. This wuld als encurage the use f utility sftware t find the addresses. Learners t research the different services and prtcls that relate t lcal and wide area netwrks. The internet which culd be cnsidered as a WAN can be easily used t research the advantages and disadvantages f the services and prtcls with the WANs and LANs. These findings culd frm the basis f a grup discussin. Understand hw netwrk hardware and sftware cmpnents are cnnected Be able t set up a simple lcal area netwrk Learners are t be encuraged t handle and use the range f netwrk cmpnents safely. This shuld be delivered where pssible as a practical activity giving the learners detailed instructins in cnnecting the hardware cmpnents tgether, installatin f netwrk cards, and physically creating peer t peer and client server netwrks. This means that the learners will have t pay careful cnsideratin t the planning f the installatin f the hardware and sftware, and will need t cnsider any health and safety issues. Wrking in small grups in a wrkshp envirnment is t be encuraged. The learners will need t knw hw t test their installatins in terms f functinality, and as a practical activity culd be presented with netwrks cntaining faults and culd create checklists and then check the functinality f the netwrk t becme familiar with the types f tests and the testing prcess. In additin t the practical envirnment there are a variety f simulatin packages such as packet tracer that will supprt the learning f cnnecting, using and testing and learners shuld als be given experience f these where pssible. The learners shuld investigate the different types f netwrk security such as firewalls, access rights t flders, files, etc, passwrds, usernames, access cntrl. As a grup r individually they shuld identify the level f security which is apprpriate t netwrks such as small lcal LANs large rganisatinal LANs, WANs, wireless netwrks. Presentatins culd be made t the larger grup and any cnflicts r misunderstandings discussed and crrected. The learners shuld have the pprtunity t set up security n practice netwrks and t create the implementatin test plans that include testing user access and permissins t web sites, access t netwrk drives and individual flders, files and sftware. www.cr.rg.uk 6
Setting up an IT Netwrk Level 2 Unit 6 SUGGESTED ASSESSMENT SCENARIOS AND TASK PLUS GUIDANCE ON ASSESSING THE SUGGESTED TASKS Assessment and Grading Criteria P1, P2, M1, M2 Fr P1, learners must describe hw the use f cmputer netwrks can imprve cmmunicatins fr individuals and rganisatins. Evidence fr criterin P2 must shw hw netwrks allw sharing f infrmatin, hardware, sftware and staffing relating if pssible t the data prtectin act. A detailed presentatin culd be used t evidence the learners wrk. The learner culd deliver this as a presentatin with supprting bservatins and statements r a detailed reprt. Fr P5, learners culd use the mdel chsen in P4 and demnstrate the chsen mdel with diagrams including explanatins n hw the hardware, sftware and addressing cmbine t supprt the netwrk cmmunicatins. They must explain and shw the cabling used and hw addressing is used t create access. Fr merit criterin M1 the learners must explain the benefits that cmputer netwrks give in terms f cmmunicatin. They culd evidence this shwing the use f sme f the fllwing: blgs, frums emails, scial netwrking, desktp sharing, vide, file sharing etc and explaining hw rganisatins can benefit frm using these methds. Fr merit criterin M2 the learner must shw they can explain hw the digital cmmunicatins flw thrugh an rganisatin. They must shw with examples f identified rganisatins hw the cmmunicatin flws int and ut f thse rganisatins. This culd be in the frm f diagrams, narrative etc with explanatins and anntatins. Assessment Criterin P3 Learners shuld describe a range f ptential faults with cmputer netwrks, as identified in the teaching cntent. This culd be evidenced by a reprt r a presentatin. Assessment Criteria P4, P5, D1 Fr P4 the learners must describe the features and services f LAN and WAN technlgies. They must als make sure that the technlgies chsen are cmplex enugh that they shw: features that include the different tplgies, whether they are ging t use peer t peer r client server services, including cmmunicatin and file transfer prtcls; they shuld include their purpses and functins tgether with examples the data security; this shuld include any access cntrl t include lgin, virus prtectin, backup, hacking and firewalls. Fr distinctin criterin D1 learners must shw they can justify the use f different netwrk setups. This culd be evidenced with leaflets, presentatins r reprts, which detail the different netwrks and justify why the netwrk is suitable and mst apprpriate fr the identified different types f users. Assessment Criteria P6, M3, D2 Learners shuld set up a basic LAN and test it fr functinality. Fr P6, this shuld be a practical activity in which the learners shuld be bserved setting up, using and testing a simple LAN. Acceptable frms f evidence culd be detailed witness statements frm the tutr supprting a detailed reprt and test plan frm the learner and culd be enhanced by clearly anntated phtgraphic evidence r a vide recrding f the activity. Fr merit criterin M3 this can be evidenced as an extensin f P6 and learners must evidence the setting up and using security such as firewalls, file and flder permissin acrss the netwrk, access cntrls, user rights and anti-virus. Acceptable frms f evidence culd be detailed witness statements frm the tutr, recrds with a reprt detailing hw they cmpleted the tasks. These can be enhanced with phtgraphic r screensht evidence. Fr distinctin criterin D2 evidence must take the frm f a detailed test plan/table which identifies the essential tests n security settings t include testing user permissins and accessibility t any banned/restricted websites. The detail culd have the learner explaining why they are ding the tests and what they expect t happen. Each test must be carried ut and the results recrded, clearly evidenced and any faults crrected and the system retested. 7
