What is a nameserver and how to find it?
A nameserver is a computer server that provides information about the domain name system (DNS) records for a domain. They are responsible for translating domain names into IP addresses, which is the language computers use to communicate with one another over the Internet. To find a nameserver, you can use the command line utility "nslookup" or use an online search engine. Additionally, most hosting companies provide their own nameservers as part of their hosting services.
What is virtual memory and cache?
Virtual memory is software that creates an abstraction of physical memory and allows programs to address more memory than is physically available. Basically, it is a piece of computer memory that is used as an extension of physical memory. It allows programs to be loaded into memory from secondary storage, such as hard drives, so that larger programs can be loaded.
Cache is the computer's short-term memory for frequently used data. This can include anything from recently accessed files to information about webpages that are stored temporarily so they load faster the next time you visit them. Cache provides a buffer between the computing device and its main memory, so that it can quickly access and store frequently-used data without having to constantly access the main memory.
