The simplest type of network is a Local Area Network (LAN). A LAN is a computer network that connects multiple devices in a single local area, such as a home, office, or campus. This type of network is designed to allow all of the connected devices to share resources, such as files and printers, and to communicate with each other.
The main elements of a LAN are Local Area Network Interface Cards (NICs), workstations, mainframes, and routers. The most commonly used LAN technologies are Ethernet, Token Ring, and ATM. LANs typically have a smaller geographic area than a Wide Area Network (WAN), and can be used to connect two or more buildings in close proximity.
They also provide increased speed and reliability when compared to WANs.
What is a network in its simplest form?
A network in its simplest form is a system of two or more computing devices that are connected together to share information and resources. Networked computing devices exchange data with each other using a combination of hardware and software which is known as network infrastructure.
Most commonly implemented as Local Area Networks (LANs) and Wide Area Networks (WANs). LANs are usually limited to a single building or site, while WANs can span multiple locations such as cities and countries.
Networks typically consist of computers, routers, switches and other devices such as printers and storage systems. Using networking hardware and software, the devices communicate with each other through various protocols and channels, allowing users to perform a variety of tasks such as file sharing, remote access and more.
Networks allow multiple users to access and share resources from the same location, making them an essential part of modern computing.
What are some common network types?
There are four main types of networks: Local Area Networks (LANs), Wide Area Networks (WANs), Metropolitan Area Networks (MANs), and Wireless Local Area Networks (WLANs).
Local Area Networks (LANs) are used to enable computer users within a small geographical area to share hardware, software, and data. LANs usually connect computers and other devices within a building such as a house, business, or school.
Wide Area Networks (WANs) connect multiple computer networks from different locations and can be of any size—spanning the entire globe. WANs provide access to a larger pool of resources, including shared resources over large geographical areas.
Metropolitan Area Networks (MANs) comprise of computers spread over a network spanning a large area such as a city, county, or small region. The networks are slightly larger than a LAN, but can be connected to multiple LANs.
They use wireless technologies and provide access to a range of services such as video, voice, digital television and multimedia.
Wireless Local Area Networks (WLANs) are essentially LANs with wireless connections between computers and other network devices such as routers and printers. They allow users to access the same data without having to physically connect the devices together with cables.
WLANs are becoming increasingly popular because they are generally easier and cheaper to set up and maintain than traditional wired LANs.
What are the 2 types of main network security concerns?
The two main network security concerns are confidentiality and integrity. Confidentiality ensures that data is only accessible to those who have the right to view or access it. This normally involves implementing various security protocols, such as authentication, authorization, and encryption, to limit access only to authorized users and protect the data from being viewed or modified by unauthorized individuals.
Integrity ensures that data is not modified or destroyed in an unauthorized manner, and that the data received is the same as the data that was sent. This can be achieved through the use of digital signature, checksums, and hashing to ensure the data is not corrupted.
Additionally, firewall tools and intrusion detection systems can be used to detect any unauthorized access to the network, and alert administrators of any potential issues.
What is common network of communication?
A common network of communication is a type of communication system that allows users to access the same network remotely or from different network locations. It typically includes a set of interconnected networks that use standard protocols to communicate with each other.
This type of communication system allows for faster and more reliable communication, as well as increased scalability and flexibility. Some examples of common networks of communication include the internet, local area networks (LANs), wide area networks (WANs), point-to-point communications, cellular networks, satellite networks, and radio networks.
In some cases, a single network can be used for different types of communications, such as voice, data, and multimedia.
Which system is common?
The most common system is the Windows operating system, which was developed by Microsoft. It is the most widely used operating system in the world, with a market share of over 70 percent. Windows is used on PCs, laptops, tablets, and embedded systems.
It is the main OS for server computers and supports various versions of software applications and technologies. Windows includes features such as the Windows taskbar, start menu, file explorer, and Windows Media Player.
It also has native support for the Internet, and allows users to connect and communicate with other computers and devices on a network.
