3. TCP sends the data in the form of packets. TRUE

4. Hub connects two different networks. FALSE

5. NIC comes by default with computers. TRUE

D. Answer the following questions.

1. Define networking?

Ans1. Networking is the process of connecting two or more devices (computers, servers, printers) to share resources, data and applications.

 

2. What is the role of a firewall?

Ans2. A firewall is a security system that protects a computer or network from unauthorized access.

3. Define protocols?

Ans3. Protocols are sets of rules used by computers connected through a network to communicate with one another.

4. Why is NIC important in networking?

ANS4. NIC (Network Interface Card) is important in networking because it allows a computer to connect to a network and communicate with other devices.

5. Write any three advantages of networking?

Ans5. Three advantages of networking are as follows:-

1.   Resource sharing

2.   File sharing and remote data access

3.   Better communication

6. What is the difference between LAN and WAN?

ANS6. LAN: A Local Area Network covers a small geographical area, typically within a single building, office, or campus. It connects devices such as computers, printers, and servers within close proximity to each other.

LAN: LANs are typically smaller in size and serve a limited number of users or devices. They are designed for local communication and resource sharing within a specific area.

 WAN: A Wide Area Network spans a large geographical area, such as cities, countries, or even continents. It connects multiple LANs and other networks over long distances, often using leased lines, fiber-optic cables, or satellite.

WAN: WANs cover larger areas and can connect LANs located in different locations. They accommodate a larger number of users and devices distributed across multiple sites or regions.

7. What is network security? What are the different ways to ensure network security?

Ans7. Network security refers to the measures and practices taken to protect computer networks from unauthorized access, misuse, malfunction, modification, destruction, or improper disclosure. Following are the ways to ensure network security:-

1.    Install Antivirus software

2.    Use a firewall

3.    Authentication and authorization

 

8. What is network architecture? Explain different types of network architecture.

Ans8. Network architecture is the physical and logical design of software, hardware, protocols and the data transmission between devices.

Types of network architecture:-

1.  Peer-to-Peer Network-

Peer-to-Peer (P2P) network is a type of network where all computers are connected and are equal. They can all share files and resources with each other. This kind of network is good for small groups, like up to 10 computers. There is no main server-each computer acts like both a server and a user. Each computer can share things like files or printers, but only if it is turned on and working.

Example: Sharing files directly with your friends or classmates on your home or school network.

2. Client-Server Network-

A Client-Server network is a type of network where there is one main computer called a server and other computers are called clients. The server is like the boss - it controls and manages everything. All files, printers, and data are stored on the server. The clients (users) connect to the server to use these resources. The server also looks after security and keeps the network safe. All communication between computers goes through the server.

Example: If Client 1 wants to send something to Client 2, it first asks the server. If the server gives permission, only then Client 1 can send the data to Client 2.
