Inkjets cartridges need to replace oft and special coated paper is required for high quality motion picture out.Task-2(iii)bCommon Printer ProblemsWhen a printer has been out of paper, or had a paper jam, or some other condition that keeps it from giving proceeds for several minutes, the lpq command ceases to indicate the p articular condition, and simply shows it as stalled(n sec), with n1000. So if you see this message, you need to go to the printer itself and find out what is wrong.On the other hand, when a condition has been corrected, the lpq command may continue to cut across the condition for about a minute more so a warning like No paper tray when the paper has just been reloaded can usually be ignored. You can likewise ignore the warning No daemon present when a job has just been submitted after the come up was empty.Task3Network seamA Network is a collection of computers cogitate to one another allowing information and resources to be shared amidst them. A network is setup by connecting the various computers through the cables, connectors and connectivity devices such as hubs or switches along with which necessary protocols for enable communication between them are implemented. Any computer can access a network presently by use a network adapter expansion card also known as Network Int erface card(NIC) and a network cable.Types of cable areCoaxial cable Contains a central wire which is insulated and on top of which in that respect is a braided wire. Coaxial cables can carry more data and are less prone to interference.Plenum cable Has an outer shield made of Teflon which is a fire wicked and which does not produce poisonous fumes when burnt.Unshielded Twisted match (UTP)cable Two cables and switched wires so that the noises of the two separate wire that are screenland in a shield of foil, so that data transmission is safer.Connectors approximately Commonly connectors in a networkAre BNC, RJ-45,AUI, ST/SC and IDC/UDC.(ii) quint different technologies are1. ASDL2. Wi Max3. IP Star4. PSIN (dial up)5. ISDN (digital)1.Adigital subscriber lineAsymmetric DSL (ADSL) works by splitting the phone line into two frequence ranges. The frequencies below 4KHz are reserved for office, and the range above that is used for data. This makes it practicable to use the line f or phone calls and data network access at the same time. This type of DSL is called asymmetric because more bandwidth is reserved for receiving data than for sending data. Asymmetric variations include ADSL standards facilitates interoperability between all standard forms of ADSL. intensitysThe net profit connection can remain open while the phone line is used for voice calls.DSL redevelopment employs phone wires between the home and the call back switching center.WeaknessADSL works by splitting the phone line into two frequency ranges.
