Building a computer network

What is network? What distinguishes a computer network from these other types of networks?

Building A Network

To build a computer network, that has the potential to grow to global proportions and to support applications as diverse as teleconferencing, video-on-demand, electronic commerce, distributed computing, and digital libraries.

What is network?

Network meant the set of serial lines used to attach dumb terminals to mainframe computers. To some, the term implies the voice telephone network. To others, the only interesting network is the cable network used to disseminate video signals.

The main thing these networks have in common is that they are specialized to handle one particular kind of data (keystrokes, voice, or video) and they typically connect to special-purpose devices (terminals, hand receivers, and television sets).

What distinguishes a computer network from these other types of networks?

Probably the most important characteristic of a computer network is its generality.

Computer networks are built primarily from general-purpose programmable hardware, and they are not optimized for a particular application like making phone calls or delivering television signals.

Instead, they are able to carry many different types of data, and they support a wide, and ever-growing, range of applications.

FAQs on Building a Computer Network - Computer Networks - Computer Science Engineering (CSE)

1. What is a computer network?
Ans. A computer network is a collection of interconnected devices, such as computers, servers, routers, switches, and other networking equipment, that are linked together to facilitate communication and data sharing between them.
2. What are the benefits of building a computer network?
Ans. Building a computer network offers several benefits, including: - Enhanced communication: Networks enable users to easily share information, resources, and collaborate with others. - Resource sharing: With a network, users can share devices like printers, scanners, and internet connections, reducing costs and improving efficiency. - Data backup and storage: Networks provide centralized data storage and backup solutions, making it easier to protect and retrieve important information. - Improved productivity: Networks enable efficient data sharing and communication, leading to increased productivity and streamlined workflows. - Scalability: Computer networks can be easily expanded as the organization grows, accommodating additional devices and users.
3. What are the basic components required to build a computer network?
Ans. The basic components required to build a computer network are: - Network devices: These include routers, switches, hubs, and modems that facilitate the connection and communication between devices. - Network cables: Ethernet cables or fiber optic cables are used to physically connect the devices in the network. - Network interface cards (NIC): These are installed in individual devices to enable them to connect to the network. - Network protocols: These are a set of rules and standards that govern the communication between devices in a network. - Network configuration: This involves assigning IP addresses, subnet masks, and other network settings to devices to ensure proper connectivity.
4. What are the different types of computer networks?
Ans. There are several types of computer networks, including: - Local Area Network (LAN): A LAN is a network that covers a limited geographical area, typically within a building or campus. - Wide Area Network (WAN): A WAN connects multiple LANs over a larger geographical area, such as connecting offices in different cities or countries. - Metropolitan Area Network (MAN): A MAN covers a larger area than a LAN but smaller than a WAN, often connecting multiple LANs within a city or metropolitan area. - Wireless Network: A wireless network enables devices to connect to the network without the need for physical cables, using technologies like Wi-Fi or Bluetooth. - Virtual Private Network (VPN): A VPN provides a secure connection over a public network, allowing remote users to access the network resources securely.
5. What are some common challenges in building and managing a computer network?
Ans. Some common challenges in building and managing a computer network include: - Security: Networks need to be protected from unauthorized access and data breaches. Implementing robust security measures, such as firewalls and encryption, is crucial. - Scalability: As the number of devices and users increases, network capacity and performance may need to be upgraded to accommodate the growing demand. - Network congestion: Heavy network traffic can lead to congestion and slow down the overall network performance. Proper network design and bandwidth management techniques can help mitigate this issue. - Network troubleshooting: When network issues arise, it can be challenging to identify and resolve the problem. Effective network monitoring and diagnostic tools are necessary for efficient troubleshooting. - Network administration: Managing and configuring network devices, ensuring proper security measures, and performing regular maintenance tasks can be time-consuming and require expertise. Skilled network administrators are essential for smooth network operations.
