The most prominent features of computer networks
The most prominent features of computer networks include global interconnection, information sharing and access, efficient data transmission, powerful communication capabilities, and security and privacy protection. This topic provides you with various articles, downloads and courses related to computer networks. I hope it will be helpful to you.
What are the most prominent features of computer networks?The most prominent feature of computer networks is “resource sharing”. Computer network refers to connecting multiple computers and their external devices with independent functions in different geographical locations through communication lines to realize resource sharing and information under the management and coordination of network operating systems, network management software and network communication protocols. Delivery computer system. Resource sharing is the main function of computer networks and the main purpose of computer networks.
What are the most prominent features of computer networks?The most prominent features of computer networks include global interconnection, information sharing and access, efficient data transmission, powerful communication capabilities, and security and privacy protection. Detailed introduction: 1. Global Internet. Through computer networks, people can easily communicate and communicate with people around the world, making the transmission and sharing of information faster and more convenient, promoting the development of globalization; 2. Information Sharing and access, through computer networks, various types of information can be easily obtained and shared, whether it is text, pictures, audio or video; 3. Efficient data transmission, etc.
What is a computer network communication system?Computer network communication system is a "data communication system"; data communication system refers to a system that connects data terminal equipment distributed in remote locations with computer systems through data circuits to realize data transmission, exchange, storage and processing; data communication system It is a combination of computers and communications. A typical data communications system mainly consists of three parts: a central computer system, data terminal equipment, and data circuits.
How to prevent military computer networks from being attacked?In recent years, with the continuous development of modern network technology, the degree of informatization of military computer networks has gradually increased. However, the sensitive information carried by military computer networks also makes them a prime target for hacker attacks. Attacks on military computer networks will not only lead to the leakage of combat plans, but may even pose a major threat to national security. So, how to ensure the security of military computer networks? 1. Establishing a theoretical model For military computer networks, it is necessary to establish a reliable security theoretical model. Unlike ordinary computer networks, military planning
The development process of computer networks can be roughly divided into several stagesThe development process of computer networks can be roughly divided into four stages: 1. The birth stage from the early 1960s to the mid-1960s, when computers and terminals were interconnected to achieve remote access; 2. The formation stage from the mid-1960s to the mid-1970s, when packet switching Technology realizes communication between computers; 3. The interconnection stage from the mid-1970s to the late 1980s, the formation of network system institutions and the standardization of network protocols; 4. The high-speed network technology stage that began in the late 1980s, and successively A series of new network technologies such as Fast Ethernet and optical fiber distributed digital interface.
