4th Assignment for Semester 1
Printer and Network
1. List down the type of printer and explain briefly.
2. What are stages we need to know when troubleshooting laser printer?
3. Why we are still using DOT matrix Printer?
4. What type of ports or interface used to connect our printer and PC?
5. What is PRINT server?
6. What is computer network?
7. Why using computer network (advantages). Also explain the disadvantages.
8. Explain what is peer to peer and server based (client server) network.
9. List down the operating system that used peer to peer server based network.
10. Explain briefly 5 different services used in computer network.
11. What do we needs if we want to setup small LAN.
12. List down the network topology. Explain the advantages and disadvantages.
13. List down the networking devices used to create LAN and WAN.
14. What media and connector used in BUS, STAR, and RING topology?
15. What do means by attenuation? How to reduce these effects?
16. List down the bandwidth for all the topology in LAN.
17. What is simplex, Half and Full Duplex.
Printer and Network
1. Solid ink – use solid wax ink sticks in a phase-change process. They work by liquefying
wax ink sticks into reservoirs, then squirting the ink onto a transfer drum where it’s coldfused onto the paper in a single pass.
Thermal printer – used primarily for printing transparency. They use thermal wax on
special roller and works by melting ink dots onto special thermal paper.
2. -
Printer not working
Paper jam
Print output slow
Laser jet 20 Mem overflow error
Poor quality
Black pages
3. Because of it is an extremely cheap running cost. It is more tolerant of the hot and dirty
operating conditions found in many industrial setting.
4. Parallel port – DB25 female and centronics 36 pins.
5. A computer or device that is connected to one or more printers and to client computers
over a network, and can accept print jobs from the computers and end the jobs to the
appropriate printer.
6. A collection of computers and devices interconnected by communications channels that
facilitate communications among users and it allows user share resources. Network may
be classified according to a wide variety of characteristic.
7. Advantages:
 File sharing
 Resource sharing
 Increased storage capacity
 Increased cost efficiency
Disadvantages:
 Security issues
 Rapid spread of computer virus
 Expensive set up
 Dependency on the main file server in
8. Peer-to-peer is a distributed application architecture that partition tasks or workloads
between peers. Peers are equally privileged, equipotent participants in the application.
They are said to form a peer-to-peer network of nodes.
Server based is a network consists of a group of user-oriented PCs that request and
receive network services from specialized computers. Servers are generally higherperformance system, optimized to provide networks services to other PCs.
9. – Lmux
- Unix
-
MS widow
Window server
Mac
10. – provide access to file
- Provide e-mail service
- Enable node on the network
- Enable processes on the network
- Respond to request from application on the network
11. – server
- Connection
- Workstations
12. – bus topology
- Ring topology
- Star topology
- Tree topology
- Mesh topology
Advantages:
 Easy to handle and implement and best suited for small networks.
 The data being transmitted between two nodes passes through all the
intermediate nodes. A central server is not required for the management of thid
topology.
 Due to its centralized nature, the topology offers simplicity of operation. It also
achieves an isolation of each device in the network.
Disadvantages:
 The able length is limited. This limits the number of station that can be
connected.
 The failure of a single node of the network can cause the either network to fail.
The movement or change made to network nodes affects the performance of the
either network.
 The network operation depends on the functioning of the central hub. Hence, the
failure of the central hub leads to the failure of the entire network.
13. – hub
- Switch
- Router
- Repeater
- Modem
14. Bus topology:

The computers are connected through a common communication media.
The connector for this topology is ‘T’ connector.
Star topology:
 Uses a separate cable for each work station. The cable connects the work
station to a central device typically a hub. With star ther is no central point of
failure in the cable.
Ring topology:
 Each computer is connected to the next computer and the last computer is
connected to the first computer,
15. Attenuation is a reduction in signal strength over distance. To reduce the effect of te
attenuation by repeater.
16. – Fully switched 100/1,000 Mbps connections to the user desktop.
- Server connections should must be 1000 Mbps or better to the switch.
- All switch uplinks should use full duplex connectivity at 1000 Mbps or better.
17. Simplex – refer to communication that occurs in one direction only.
Half duplex – channel can and receive, but not at the same time. It’s like a one-lane
bridge where two ways traffic must give way in order to cross. Only one transmits at a
time, the other end receives.
Full duplex – is a data that travel in both directions simultaneously. There is no need
switch from transmit to receive mode like in half duplex. It’s like a two lane bridge on a
two-lane highway.
