What is Network Security
A network is a system in which two or more computers and digital devices are connected to each other to share information, resources, and services. Through a network, users can exchange data such as files, messages, and multimedia quickly and efficiently. It also allows sharing of hardware like printers, scanners, and internet connections, reducing cost and improving productivity. Networks are widely used in homes, schools, offices, banks, and hospitals to enable smooth communication and teamwork. The internet itself is the largest network in the world. In simple terms, a network helps devices communicate with each other easily and work together effectively.
What is Encryption
Encryption is a method of protecting information by converting it into a secret code so that only authorized people can read it. When data is encrypted, it becomes unreadable to hackers or anyone who does not have the correct key or password to unlock it.
It is commonly used to secure:
• Online banking transactions
• Passwords and personal details
• Messages and emails
• Files stored on computers and phones
📌 In simple words:
Encryption keeps data safe by hiding it in a coded form.
It helps protect privacy and prevents misuse of important information in the digital world.
