প্রশ্নঃ কম্পিউটার নেটওয়ার্কিং কি ? কাকে বলে ?
উত্তরঃতথ্য ও উপাত্ত আদান প্রদান করার জন্য এক বা একাধিক কম্পিউটার ও কম্পিউটিং ডিভাইসকে একটি নির্দিষ্ট পদ্ধতিতে সংযোগ স্থাপন করার প্রক্রিয়াকে কম্পিউটার নেটওয়ার্ক বলে ।

PAN - Personal Area Network::The smallest and most basic type of network, a PAN is made up of a wireless modem, a computer or two, phones, printers, tablets, etc., and revolves around one person in one building.
LAN - Local Arae Network :: LAN connect groups of computers and low-voltage devices together across short distances (within a building or between a group of two or three buildings in close proximity to each other) to share information and resources. Enterprises typically manage and maintain LANs.
WLAN - Wireless Local Arae Network:: Functioning like a LAN, WLANs make use of wireless network technology, such as WiFi. Typically seen in the same types of applications as LANs, these types of networks don’t require that devices rely on physical cables to connect to the network.
CAM - Campus Area Network:: Larger than LANs, but smaller than metropolitan area networks (MANs, explained below), these types of networks are typically seen in universities, large K-12 school districts or small businesses. They can be spread across several buildings that are fairly close to each other so users can share resources.
MAN - Metropolitan Area Network :: These types of networks are larger than LANs but smaller than WANs – and incorporate elements from both types of networks.
WAN - Wide Area Network :: The Internet is the most basic example of a WAN, connecting all computers together around the world. Because of a WAN’s vast reach, it is typically owned and maintained by multiple administrators or the public.
SAN - Storage Area Network :: As a dedicated high-speed network that connects shared pools of storage devices to several servers, these types of networks don’t rely on a LAN or WAN. Instead, they move storage resources away from the network and place them into their own high-performance network. SANs can be accessed in the same fashion as a drive attached to a server. Types of storage-area networks include converged, virtual and unified SANs.
SAN - System Area Network :: This term is fairly new within the past two decades. It is used to explain a relatively local network that is designed to provide high-speed connection in server-to-server applications (cluster environments), storage area networks (called “SANs” as well) and processor-to-processor applications. The computers connected on a SAN operate as a single system at very high speeds.
POLAN - Passive Optical Local Area Network :: As an alternative to traditional switch-based Ethernet LANs, POLAN technology can be integrated into structured cabling to overcome concerns about supporting traditional Ethernet protocols and network applications such as PoE (Power over Ethernet). A point-to-multipoint LAN architecture, POLAN uses optical splitters to split an optical signal from one strand of singlemode optical fiber into multiple signals to serve users and devices.
EPN - Enterprise Private Network :: These types of networks are built and owned by businesses that want to securely connect its various locations to share computer resources.
VPN - Virtual Private Network :: By extending a private network across the Internet, a VPN lets its users send and receive data as if their devices were connected to the private network – even if they’re not. Through a virtual point-to-point connection, users can access a private network remotely.
