Note: Answer all questions. Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme.

Question. 1. Elaborate the concept of computer networks. Briefly explain the different types of networks.

a) Concept of computer networks

Answer: A computer network or data network is a telecommunications network which allows nodes to share resources. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet.

Network computer devices that originate, route and terminate the

b) Types of computer networks

Answer: One way to categorize the different types of computer network designs is by their scope or scale. For historical reasons, the networking industry refers to nearly every type of design as some kind of area network. Common types of area networks are:

·       LAN - Local Area Network

·       WAN - Wide Area Network

·      WLAN - Wireless Local Area Network

Question. 2. Write Short notes on:

a) Connectors

Answer: An electrical connector, is an electro-mechanical device used to join electrical terminations and create an electrical circuit. Electrical connectors consist of plugs (male-ended) and jacks (female-ended). The connection may be temporary, as for portable equipment, require a tool for assembly and removal, or serve as a permanent electrical joint between two wires or devices. An adapter can be used to effectively bring together dissimilar connectors.

b) PC Cards

Answer: In computing, PC Card is a configuration for computer parallel communication peripheral interface, designed for laptop computers. Originally introduced as PCMCIA, the PC Card standard as well as its successors like CardBus were defined and developed by the Personal Computer Memory Card International Association (PCMCIA).

It was originally designed as a standard for

c) Hubs

Answer: A hub is a common connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

What Hubs Do

d) Bridges

Answer: “A device used to connect two separate Ethernet networks into one extended Ethernet. Bridges only forward packets between networks that are destined for the other network. Term used by Novell to denote a computer that accepts packets at the network layer and forward them to another network.”

Why Use Bridges?

Question. 3. Explain the Elements of Communication System. Elaborate on Modulation/Demodulation (Modem)

a) Explanation of the Elements of Communication System

Answer: As mentioned before, the purpose of a communication system is to transmit intelligence signal from a source to a destination at some point away from the source. Figure 1 is a block diagram of a communication system. This system consists three

b) Elaborate on Modulation/Demodulation (Modem)

Answer: QAM (quadrature amplitude modulation) is a form of modulation, to provide an example.  It's the technology that allows data (digital information) to be transmitted over a medium, using frequency and amplitude (as a signal).  There are many modulation variations, based on one more more concepts:  amplitude, frequency,  phase and others.

The idea is, a modem is able to modulate (co

Q4. Identify and explain the five types of classes of IP Address. Also write few points on Private and Public IP Addresses.

a) Explanation to the five types of classes of IP Address.

Answer: The 5 classes of IP addresses were created as the original Internet routing scheme in the 1970's.  These 5 classes were proposed by the IEEE committee. These classes were not created, after the fact, to meet the needs of an ever expanding Internet. When the IEEE proposed these classes; each of the 5 classes were 'designed' for a specific purpose.

b) Private and Public IP Addresses.

Answer: A public IP address is an IP address that can be accessed over the Internet. Like postal address used to deliver a postal mail to your home, a public IP address is the globally unique IP address assigned to a computing device. Your public IP address can be found at What is my IP Address page. Private IP address on the other hand is used to assign computers within your private space without letting them directly expose to the Internet

Question. 5. Briefly discuss concept of Network Management Tools and Applications.

a) Network Management Tools.

Answer: The Network Management toolset of the OpUtils software monitors network performance, calculates the bandwidth utilization, and scans the traffic for errors through SNMP. The tool also provides asset details such as the OS, installed software, and hardware and informs you about the general availability and performance of the network

b) Network Management Applications.

Answer: In the network management model, a network management application (NMA) is the software that sits on the network management station (NMS) and retrieves data from management agents (MAs) for the purpose of monitoring and controlling various devices on the network. It is defined by the ISO/OSI network management model and its subset of protocols, namely Simple Network Management Protocol (SNMP) and Common

Question. 6. Explain the Working, benefits and limitations of Cloud Computing.

a) Explanation to the Working of Cloud Computing.

Answer: From floppy disks to CDs to USB flash drives, file saving and sharing has undergone a significant evolution over the past decades. The devices to share files are becoming smaller and have higher capacities, increasingly destined to serve an on-the-go lifestyle.

Today you no longer need to save all your documents on one particular device. Instead, you can access your files from any terminal at any time, thanks

b) Explanation to the benefits of Cloud Computing.

Answer: Advantages

·       Worldwide Access. Cloud computing increases mobility, as you can access your documents from any device in any part of the world. For businesses, this means that employees can work from home or on business trips, without having to carry around documents. This increases productivity and allows faster exchange of information. Employees can also work on the same document without having to

c) Explanation to the limitations of Cloud Computing.

Answer: Disadvantages

·       Security. When using a cloud computing service, you are essentially handing over your data to a third party. The fact that the entity, as well as users from all over the world, are accessing the same server can cause a security issue. Companies handling confidential information might be particularly concerned
