Proxy is: Definition, Function, How it Works & Benefits
The following is a complete discussion about proxies starting from their meaning, functions, how they work and their benefits.
Definition of Proxy
A proxy is a server that provides a service to forward every user request to another server on the internet. Another definition of proxy is a computer program that acts as a link between a computer and the internet.
Proxy Function
The proxy function is as follows:
1. Connecting Sharing Function
As a connecting sharing proxy, it functions as a liaison or intermediary in retrieving data from an IP (Internet Protocol) address to another IP address or it can also be to a computer's IP user/users.
2. Filtering Function
In the filtering function there are several proxies that are equipped with firewalls that can block some or an unwanted IP address, therefore some websites cannot be accessed using a proxy the.
3. Caching Function
The chaching function is a function where a proxy is equipped with data storage media from a web, from queries or user access requests. For example, a request to open/access a website can be faster if there has been a previous request to access a website from a proxy user.
Caching is a process of storing objects and data that have been requested by proxy users when using them for browsing and making internet connections on internet applications.
For example, when we access a website or site, images and objects on the website will be stored in the proxy in cache form. The caching process is easier to do with a proxy server, where every data and object that has been previously accessed or requested will be stored on the proxy server.
How Proxies Work
The way a proxy works is very simple, when a user uses a proxy service and then requests files or data which is on a public server (internet) then the proxy will forward it to the internet, so it is as if the proxy is the one request.
The proxy will show a response to the user as if it were the public server, when the proxy server has got what the user requested. That's how proxies work
Proxy Benefits
Having a proxy for users will be very helpful and beneficial. The following are some of the benefits of using proxies:
- There is an increase in network performance.
- Used as a filter if there is a request for data from a website.
- Can reduce bandwidth usage from the user's internet connection.
- Internet network performance increases.
- Can block certain websites or sites.
- Maintain better and more secure network security.
What a Proxy can do
Some things a proxy can do are as follows:
- Can hide an IP (Internet Protocol) address.
- Can be used to open/access a website or site that is blocked by an organization's ISP (Internet Service Provider).
- Can be used to block several or one websites/sites that cannot be accessed or opened later
- You can filter out unwanted items and encrypt all cookies that have been stored.
- Can increase user privacy security.
Proxy Advantages and Disadvantages
Apart from the explanation above, proxies also have advantages and disadvantages, see the review.
Advantages of Proxies
- A network's security is maintained, because the proxy acts as a barrier between the local network and the external network (internet).
- Sites or websites that have been accessed previously can be reopened and be faster, because access does not require an external internet network but is already in the proxy cache directory.
- There are filtering facilities, including filters for users, content and access times.
Disadvantages of Proxies
- If a website has never been opened before, access to the website will be slower, because the client has to request it first go to the proxy, after that the proxy will request or request from the client to the service provider Internet.
- If a proxy is late in updating the cache, the client will get content that has not been updated when requesting content.
Thus has been explained about Proxy is: Definition, Function, How it Works & Benefits, hopefully it can increase your insight and knowledge. Thank you for visiting.
