End systems connect directly to the Internet and allow users to send and receive data. Examples include personal computers and cameras. Users access servers through their own computers, creating an interconnected network. Data transfer speed depends on various factors, and end systems may be vulnerable to viruses and security breaches. Security measures such as encryption, access restriction, and monitoring can help protect sensitive data.
An end system is a device that connects directly to the Internet, creating an interface that individual users can access. Final systems take many forms. They allow users to interact directly with the Internet to send and receive data, and can be used for everything from processing orders for a business to sending pictures of a family vacation.
An example of a final system is a personal computer. The computer has applications that people can use to perform tasks such as checking e-mail, surfing the Internet, uploading files, and so on. In addition to personal computers, devices such as cameras can also be connected to the Internet as end systems, as happens when people use webcams to chat with each other.
Users do not directly access other end systems, but facilitate Internet communications. This includes servers for data such as email and web pages. Users connect to these end systems through their own computers, which contact the server to access and transfer information. Together, these create an interconnected network of end systems, which forms the Internet architecture that allows people to exchange information globally via a variety of channels.
How quickly data can be transferred depends on a number of factors, including the location of the computers involved, the types of connections established, and whether or not there are access controls. Some ISPs, for example, limit bandwidth transfers from their customers. These companies can monitor their traffic flows to ensure that their systems don’t get clogged with heavy user requests.
As a primary entry point, an end system may be vulnerable. Viruses often target end systems, infecting them and establishing a foothold that can be used to infect other end systems as the infected computer exchanges data with them. They also create security holes, because a computer designed for data transfer can be penetrated and used by unauthorized individuals who want to obtain proprietary information or access other private data.
In situations where an end system with sensitive data is used, a variety of security measures can be taken to make it more secure. These measures include encrypting your data, restricting access to your device, and monitoring your traffic for signs of abnormalities that might suggest that someone unauthorized is accessing your computer. Regularly backing up your data to protect against viruses and changing passwords for security is also a key part of maintaining the security of your end system.
