Ð ÐCost efficiency: By consolidating resources, networks help reduce operational costs. For example, rather than each
                 employee purchasing software licenses, companies can install software on a server and provide shared access to
                 all users.
              Ð ÐRemote access:  Networks  enable  users  to  access  resources  from  remote  locations,  supporting  flexible  work
                 arrangements. Employees can connect to their office network via Virtual Private Networks (VPNs), ensuring secure
                 access while working from home.

              Ð ÐSecurity: Networks can implement robust security measures, such as firewalls and encryption, to protect sensitive
                 data. Organisations often adopt security protocols to restrict access only to authorised personnel.

              Ð ÐBackup  and  recovery:  Centralised  backup  solutions  enable  automatic  data  saving,  simplifying  recovery  in  the
                 event of data loss. Companies often use backup servers to store critical data copies, ensuring quick recovery from
                 hardware failures.

              Ð ÐScalability:  Networks  can  be  easily  expanded  by  adding  new  devices  or  resources  without  causing  significant
                 disruptions. For example, a growing business can integrate more computers into the network seamlessly.

              Disadvantages of Network
              Several disadvantages of a network are as follows:

              Ð ÐSecurity  issues:  Networks  are  susceptible  to  cyber  threats  such  as  hacking  and  malware  attacks,  which  can
                 compromise sensitive data. For instance, a data breach in a corporate network could expose personal information,
                 leading to significant financial and reputational damage.

              Ð ÐCost of setup: Establishing a network can be expensive due to the costs associated with hardware, software, and
                 installation. Organisations often need to invest in routers, switches, and cabling, which can quickly add up.

              Ð ÐMaintenance requirements: Networks require regular monitoring, maintenance, and troubleshooting to ensure
                 smooth operation and security. IT staff must continually update software, manage hardware failures, and monitor
                 network performance.

              Ð ÐData privacy: Sharing data across a network increases the risk of unauthorised access and potential privacy breaches.
                 For example, employees accessing sensitive customer information might inadvertently expose it to unauthorised
                 personnel.

              Ð ÐNetwork  failure:  If  a  network  experiences  downtime  or  failures,  it  can  halt  business  operations  and  result  in
                 productivity losses. A power outage affecting the main server could prevent all connected users from accessing
                 necessary resources.
              Ð ÐComplexity: Larger networks can become complex, requiring specialised knowledge and tools to manage effectively.
                 Managing a multi-site network with various devices and configurations may necessitate skilled IT professionals.
              Ð ÐDependency on central server: Many networks rely on a central server to manage resources; if it fails, users may
                 lose access to critical services. For example, if a business uses a central database, a server crash could prevent
                 employees from accessing customer records.

              Ð ÐVirus and malware spread: When one device on the network becomes infected, malware can quickly spread to
                 other connected devices. A single compromised computer can infect the entire network, leading to widespread
                 data loss.

              Terminologies of Networking
              There are various terminologies of networking like client, server, network interface card, etc. Let us now understand
              some of them.

              Nodes (Workstations)
              A node is defined as a connection point or device connected to a network that is able to send, receive, or forward
              information. When a computer is connected to a network, it becomes a node (also known as a workstation). On a
              network, each user has their own workstation. There would be no network if there were no nodes.
