NETWORKING

TO REVIEW COMPUTER NETWORKING TO PASS THE TEST :)

WHAT IS COMPUTER NETWORKING?

WHAT IS COMPUTER NETWORKING?

collection of interconnected devices that communicate and share resources with each other topologies and its definition.

FOUR TYPES OF UNDERSTANDING THE IMPORTANCE OF NETWORK

• communication

• resource sharing

• data management

• efficiency and productivity

• scalability
  

COMMUNICATION

facilitates instant messaging, emails, video calls, and collaboration tools

RESOURCE SHARING

enable sharing of files, applications, and hardware resources like printers, and storage devices.

DATA MANAGEMENT

centralize data storage and management, improving security and accessibility.

EFFICIENCY AND PRODUCTIVITY

enhances business operations by allowing remote access to resources and reducing redundancy.

SCABILITY

supports the growth of businesses by easily expanding network capabilities.

COMMON USES OF COMPUTER NETWORK

• file sharing

• internet access

• application sharing

• security

FILE SHARING

networks allow users to share files and documents across multiple devices

INTERNET ACCESS

networks provide internet connectivity to devices, enabling web browsing, email, and online services

APPLICATION SHARING

networks support shared applications like database systems, collaboration tools, and communication platforms.

SECURITY

networks implement security measures such as firewalls, encryption, and access controls to protect data and resources.

NETWORK FEATURES

• performance

• reliability

• security

PERFOMANCE

a computer network is measured in terms of response time. The response time of sending and receiving data from one node (computer in a computer network are often referred as node) to another should be minimal.

RELIABILITY

there should not be any failure in the network or if it occurs the recovery from a failure should be fast

SECURITY

a computer network should be secure so that the data transmitting over a network should be safe from unauthorized access.

PROPERTIES OF GOOD NETWORK

• interpersonal communication

• resources can be shared

• sharing files and data

INTERPERSONAL COMMUNICATION

we can communicate with each other efficiently and easily

RESOURCES CAN BE SHARED

we can share physical resources by making them available on a network such as printers, scanners etc.

SHARING FILES AND DATA

authorized users are allowed to share the files on the network.

TYPES OF NETWORK AND ITS DEFINITION

• devices

• repeater

• hub

• modem

DEVICES

NIC are hardware components that connect a computer or other device to a network.

REPEATER

regenerate and amplify signals to extend the distance over which data can travel in a network

HUB

basic networking devices that connect multiple computers in a LAN.

MODEM

modulate and demodulate signals for data transmission over phone lines, cable systems, or satellite links, enabling internet access
