Computer maintenance is the practice of keeping computers in a good state of repair.

Compression works by eliminating or minimizing redundancy in a file, making your files smaller without losing any information.

. Every character on your computer, every letter, digit and punctuation mark, is actually made up of several characters that make up computer code.

A simple example of compression is: If you have a set of characters "AAAADDDDDDD" representing a letter, one type of compression software can rewrite this as "4A7D", saving seven spaces and making that line 64% smaller.

Example

A firewall is a device or set of devices designed to permit or deny network transmissions based upon a set of rules

It is frequently used to protect networks from unauthorized access while permitting legitimate communications to pass.

Many personal computer operating systems include software-based firewalls to protect against threats from the public Internet.

Many routers that pass data between networks contain firewall components

A personal firewall is an application which controls network traffic to and from a computer, permitting or denying communications based on a security policy

• There are several classifications of firewalls depending on where the communication is taking place, where the communication is intercepted and the state that is being traced.

• Network layer and packet filters : Network layer firewalls, also called packet filters, operate at a relatively low level of the TCP/IP protocol, not allowing packets to pass through the firewall unless they match the established rule set.

• Application-layer : Application-layer firewalls work on the application level of the TCP/IP stack, and may intercept all packets traveling to or from an application.
