A can be categorized into different types, such as , , and , depending on its size and reach. LAN, or Local Area Network, is a network confined within a limited area like an office building or a home. In contrast, WAN, or Wide Area Network, covers a larger geographical area, such as multiple offices in different locations, allowing for communication over long distances. On the other hand, PAN, or Personal Area Network, refers to a network that connects personal devices like smartphones, tablets, and laptops.
The network defines the arrangement or structure of interconnected devices and their communication paths. A is a fundamental device in any network that forwards data s between different networks, while a connects devices within a network, enabling efficient data transmission. A provides network security by filtering incoming and outgoing network traffic based on predefined security rules.
Each device on a network is identified by an , a unique numerical label. When data is transmitted over a network, it is divided into smaller units called packets. refers to the maximum amount of data that can be transmitted over a network in a given time, while represents the delay in data transmission. is the network's ability to accommodate a growing number of users or devices, while ensures the prioritization and efficient delivery of critical data.
A enables secure communication over a public network like the internet by encapsulating data in encrypted packets. VPN provides features like , allowing network administrators to allocate bandwidth based on specific needs. The rise of the (IoT) has led to the proliferation of such as fitness trackers and , which collect and transmit data for and .
utilize network connectivity to control various appliances and devices, enabling features like , , and personalized entertainment. and are essential for securing the transmission of data over a VPN. s, such as and , provide and facilitate remote access. s connect multiple networks, while s allow individual users to access a network from remote locations.
(SAN) employ high-speed networks, like , to provide centralized and shared storage resources. technology ensures data redundancy and fault tolerance, while s enable point-in-time backups. A comprises multiple disk drives, typically organized in a RAID configuration, for storage purposes.
