Computer mainframe: usually used for personal or family use, the configuration depends on the user's needs, and it is used to handle daily affairs, such as office, web browsing, entertainment, etc.
Server: A high-performance computer, which is used to process a large amount of data, run applications and provide network services. High-performance CPU, memory and storage devices are usually configured to meet the requirements of 24/7 uninterrupted operation.
2. Stability and reliability
Computer mainframe: Generally, lower stability and reliability are required, because failures usually only affect a single user.
Server: Extremely high stability and reliability are required, because failure may affect multiple users or the whole network. Redundant power supply, RAID array and other measures are usually adopted to improve reliability.
3. Extensibility and upgrade
Computer mainframe: the expansibility and upgrade are relatively limited, and it is generally only necessary to meet personal needs.
Server: Require high scalability and upgradeability, so as to upgrade hardware and software according to business requirements. Generally, more memory slots, hard disk bits and PCIe slots are supported.
4. Operating system and software
Computer host: Generally, desktop operating systems such as Windows, macOS or Linux, and various daily application software are used.
Server: Use specialized server operating systems, such as Windows Server and Red Hat Enterprise Linux, and run specific server software, such as Web server, database server and mail server.
5. Price and maintenance cost
Computer mainframe: the price is relatively low and the maintenance cost is also low.
Server: The price is higher because of higher performance hardware and more stable components. At the same time, the maintenance cost is also high, because the components need to be checked and replaced regularly to ensure the stable operation of the server.
6, network connection and security
Computer host: usually only connected to the home or office LAN, the network security requirements are relatively low.
Server: Connect to a wider network environment, such as intranet or Internet, so the network security requirements are higher. Firewalls, intrusion detection systems and other measures are usually used to improve security.
The above is the main difference between server and computer host, I hope I can help you!
