The limpel-ziv (lz77) compression technique is used by the GNU zip (gzip) tool to produce a compression ratio of 60–70%.
<h3>How do methods for data compression function? Describe the LZW algorithm.</h3>
Compression methods lower the amount of memory needed to hold pictures and the number of bytes needed to represent data. Compression improves the amount of data that can be delivered over the internet and enables the storage of more photos on a given media.
Abraham Lempel, Jacob Ziv, and Terry Welch developed the table-based lookup technique known as LZW compression to compress a file into a smaller file. The TIFF image format and the GIF image format are two frequently used file formats that employ LZW compression.

Answer:
Your computer does not support this code because you have put spaces in between the code, or maybe that is how you have written the question.
Clickstream tracking tools collect data on customer activities at websites- true.
<h3>
what is the website?</h3>
- A website, often known as a website, is a collection of web pages and associated material that is published on at least one web server and given a shared domain name.
- The World Wide Web is the aggregate name for all publicly accessible websites.
- A company's internal website for its workers is an example of a private website that can only be viewed via a private network.
- Most websites focus on a single subject or objective, including news, education, business, entertainment, or social networking.
- The navigation of the website, which frequently begins with a home page, is aided by hyperlinks between web pages.

Answer:
B. Symmetric key encryption
Explanation:
Symmetric key encryption is one in which a single encryption key is sent to the receiver so both sender and receiver share the same key. In this type of encryption, the sender uses a particular key to encrypt the data and sends the encrypted data (cipher data) to the receiver and then the receiver uses the same key to decrypt the data.
Public key encryption, or asymmetric encryption uses two keys - a private key and a public key. The public key is know to everyone while the private key is known only to those for whom the message is intended. An application of this type of encryption is in SSL (Secure Sockets Layer) - a protocol for transmitting data privately on the internet.
Private key encryption is not exactly one of the encryption methods but rather, a private key and a public key are used in encryption.
The best option is therefore <em>symmetric key encryption</em>.
