Hard Drive and Memory are both used for the same purpose of storing data. For long-term data retention, we need to use the Hard Drive storage device. On the other hand, the memory storage device is used for short-term data retention. Hard Drive or HDD is slower than the memory but it stores more data. Memory or RAM (Random Access Memory) is faster as compared to the Hard Drive but data will be lost when the power supply is switched off. Read this article to find out more about Hard Drive and Memory and how they are different from each ... Read More

Egrep and Fgrep, two different command-line utilities, are used to search for text patterns in files. These two commands are often used in operating systems built on Unix, like Linux and macOS. An enhanced version of the ordinary grep tool is known as "extended grep." It supports the use of extended regular expressions, which enable searches that are more complicated than those possible with standard grep. fgrep, which stands for "fixed grep, " is designed to search for fixed strings rather than patterns. Because of this, fgrep is quicker than grep and egrep but also less customizable. We ... Read More
Cable modems and DSL modems are both devices that allow you to connect your computer to the Internet. But what’s the difference between DSL modem and cable modem?
