Dash is a computer network created for an individual person

How does a computer network work? Devices attached to a computer network use Network systems must follow certain standards or guidelines to operate. Standards are a set of data communication rules required for the exchange of information between devices and are developed by various standards organizations, including A computer network must be physically and logically designed in such a way that makes it possible for the underlying network elements to communicate with each other. This layout of a computer network is known as the computer network architecture. The following are the two most common computer network architectures: • Client-server. This model consists of many clients -- or nodes -- where at least one network node acts as the central server. The clients in this model don't share resources, but request the central server, as all the resources are installed on it. • Peer-to-peer (P2P). Each connected device on this network behaves as the client, as well as the server, and enjoys similar privileges. The resources of each peer are shared among the entire network, including memory, processing power and printing. Many companies use the A well-defined computer network also takes An image comparing client-server and P2P network architectures Core components of a computer network The following building blocks -- network devices, links and communication protocols -- make computer network operations possible: • Network devices. These physical devices or nodes are the data ...

Computer networks can include two to any number of devices communicating with each other. Study the networks that handle the distributed processing of computer networks, including the personal area network (PAN), local area network (LAN), metropolitan area network (MAN), and wide area network (WAN). Updated: 08/26/2021 In a typical day, you probably use several different computer networks. After getting up in the morning as you eat your breakfast, you check your email on your tablet over a Wi-Fi connection in your house. Network number 1. When you get to work, you log onto your computer and start using a number of files from the company's database. Network number 2. When you go out for a coffee, you check the latest scores on your tablet using the Wi-Fi hotspot of the local coffee shop. Network number 3. And it's only 11 a.m. A personal area network, or PAN, is a computer network organized around a single individual person within a single building. This could be inside a small office or a residence. A typical PAN would include one or more computers, telephones, peripheral devices, video game consoles and other personal entertainment devices. If multiple individuals use the same network within a residence, the network is sometimes referred to as a home area network, or HAN. A local area network, or LAN, consists of a computer network at a single site, typically an individual office building. A LAN is very useful for sharing resources, such as data storage and printers. LANs...

Uses of Computer Networks • Communicating using email, video, instant messaging, etc. • Sharing devices such as printers, scanners, etc. • Sharing files. • Sharing software and operating programs on remote systems. • Allowing network users to easily access and maintain information. Types of Computer Networks There are mainly five types of Computer Networks • • • • • Local Area Network (LAN) 3. Campus Area Network (CAN) CAN is bigger than a LAN but smaller than a MAN. This is a type of computer network that is usually used in places like a school or colleges. This network covers a limited geographical area that is, it spreads across several buildings within the campus. Its transmission speed is very high with a moderate maintenance cost and moderate cost. Examples of CAN are networks that cover schools, colleges, buildings, etc. Metropolitan Area Network (MAN) 5. Wide Area Network (WAN) WAN is a type of computer network that connects computers over a large geographical distance through a shared communication path. It is not restrained to a single location but extends over many locations. Here we use Leased-Line & Dial-up technology. Its transmission speed is very low and it comes with very high maintenance and very high cost. The most common example of WAN is the Internet.

Computer networks: Who hasn’t heard of them? We connect to them all the time, whether we’re at home, school, or work. But what exactly is a computer network, and what do developers need to know about them? Simply stated, a computer network is a group of connected computers that share data with each other. A computer network can be as simple as two laptops connected by a short cable or as complex as the Internet — and yes, the Internet is a type of computer network. Below, we’ll walk through the fundamentals of computer networks and how they work, basic networking terms, and common types of computer networks. What do computer networks do? Computer networks allow two or more computers to exchange, transmit, or share data and resources. And while early networks involved Why are networks important? Computer networks are everywhere we go. Most importantly, they let us quickly exchange ideas and files with each other. Without them, we’d still be relying on floppy disks and CDs. Today, computer networks allow us to share what’s on our computers and devices while managing what information is public or stays private. Computer networks also allow us to use resources more efficiently. For example, companies can set up a single network printer accessible by everyone or a single shared storage drive instead of paying for separate storage for each computer. Computer network terms Here are some common network terms and devices that every developer should know. Bandwidth Bandwidth is a me...

The components of the system you can physically touch - the system unit (tower, desktop, laptop), internal devices and peripheral devices (keyboards and monitors) - are called hardware. It is important to remember that basic definition: Hardware are the parts of the computer that are tangible and can be touched. That particular type of software is the operating system software. Software, as a general term, is the set of instructions written to direct the computer to execute specific tasks. Operating system software is typically written for a specific type of computer. The operating system, or just system software, instructs the hardware to get moving when the power is turned on or the mouse is moved, deactivating a sleep mode. It interprets instructions from applications software to utilize peripherals and/or storage devices. An example is Microsoft Windows 7 for a PC-based computer or Mac OS X for a Macintosh. Microsoft is semi-unique in that it produces not only operating system software, but application software as well. Application software, or productivity software, is the set of instructions installed in a computing device that lets us do something. There are thousands of software programs out there, but a few examples you may be familiar with are iTunes, Microsoft Word and Adobe Reader. Both application and system software are sold to individual users; however, there are versions that can be used in a network environment. A computer network is a grouping of computer...
