QUIZ 1 (EC 301)

2.

A set of rules that has to be followed by the network computers to communicate with each other.

Topology
Architecture
Protocol
Terminal

Correct Answer

A. Protocol

Explanation

A protocol refers to a set of rules that network computers must adhere to in order to communicate effectively with each other. These rules govern how data is transmitted, received, and interpreted, ensuring that the information is exchanged accurately and efficiently. By following the protocol, network devices can establish a standardized method of communication, enabling seamless data transfer and interoperability between different systems and devices.

Which one has the widest coverage?

LAN
WAN
MAN

Correct Answer

A. WAN

Explanation

A WAN (Wide Area Network) has the widest coverage among the options provided. LAN (Local Area Network) refers to a network that covers a small geographical area like a home or office, while MAN (Metropolitan Area Network) covers a larger area like a city. A WAN, on the other hand, covers a wide geographical area, often spanning multiple cities or even countries. Therefore, a WAN has the broadest coverage compared to LAN and MAN.

A network topology in which all data/information pass through a central device is

Bus
Star
Ring
Mesh

Correct Answer

A. Star

Explanation

In a star network topology, all data/information pass through a central device known as a hub or switch. This central device acts as a central point of communication, connecting all the devices in the network. Each device in the network is connected to the central device, allowing for efficient data transmission and easy management of the network. This topology provides better performance and reliability as compared to other topologies like bus or ring, as any issue with one device does not affect the entire network.

What is a server?

Any combination of hardware or software designed to provide service to client
Install in the PC thah allows to plug ethernet or wireless connection
Part of network that gives the data out

Correct Answer

A. Any combination of hardware or software designed to provide service to client

Explanation

A server refers to any combination of hardware or software that is specifically designed to provide services to clients. This can include various components such as computer servers, network servers, or web servers. The purpose of a server is to respond to client requests and deliver the requested data or services. Servers are an essential part of networks as they facilitate communication and data exchange between clients and other devices on the network.

6.

what does a ROUTER do in a network?

Prevents hackers getting into your computer.
Sends and receives data packets by looking at the destination.
Gives directions to other people on the network.

Correct Answer

A. Sends and receives data packets by looking at the destination.

Explanation

A router in a network is responsible for sending and receiving data packets by examining the destination. It acts as a traffic controller, directing data packets to their intended destinations within the network. This is achieved by analyzing the destination address of each packet and determining the most efficient path for it to follow. Unlike a firewall, which is designed to prevent unauthorized access to a computer, a router focuses on efficiently routing data within the network.

What is disadvantages of computer networking?

Connectivity and communication
Sharing
Data security concerns
Entertainment

Correct Answer

A. Data security concerns

Explanation

Data security concerns are a disadvantage of computer networking. When computers are connected in a network, there is a risk of unauthorized access, data breaches, and cyber attacks. This can lead to the loss or theft of sensitive information, financial losses, and damage to reputation. Organizations need to invest in robust security measures, such as firewalls, encryption, and regular updates, to mitigate these risks. Failure to address data security concerns can have serious consequences for individuals and businesses, making it an important disadvantage of computer networking.

8.

Computer Network is

Collection of computer and devices
Interconnected by communication channels
Communication and sharing of resources and information
All above

Correct Answer

A. All above

Explanation

The correct answer is "All above" because a computer network is indeed a collection of computers and devices that are interconnected by communication channels. This allows for communication and sharing of resources and information between the connected devices. Therefore, all of the given options accurately describe what a computer network is.

9.

Which one is NOT a type of Topology.

TREE
STAR
BUS
MESH

Correct Answer

A. TREE

Explanation

The correct answer is TREE because tree is a type of topology. In a tree topology, devices are connected in a hierarchical structure, similar to branches on a tree. This type of topology is commonly used in wide area networks. On the other hand, star, bus, and mesh are all types of network topologies. In a star topology, devices are connected to a central hub. In a bus topology, devices are connected in a linear fashion, sharing a common communication line. In a mesh topology, devices are connected to each other in a network where every device has a direct connection to every other device.

A connection point, either or redistribution or a communication endpoint is called.................

Workstation
Host
Node
Segment

Correct Answer

A. Node

Explanation

A connection point, either for redistribution or a communication endpoint, is called a "node". This term is commonly used in computer networks to refer to a device or a piece of equipment that is connected to a network and can send, receive, or forward data. It can be a computer, a server, a router, or any other network-enabled device. The term "node" is used to describe the point at which connections are made and data is exchanged within a network.
