How to use clrscr() function in c, c++ program in Ubuntu or in Linux

It is very simple to use the substitute of clrscr() function in Ubuntu. I have used it in Ubuntu terminal and i think it would work properly in other Linux OS.

#include<iostream>
#include<cstdlib>
using namespace std;

main()
{
system("clear");
.... ... ...
.... ... ...
}

What is the purpose of jam signal in CSMA/CD?

First, beware that modern switched Ethernet LANs are not CSMA/CD anymore. CSMA/CD was a technique that applied to 10mbit/sec and 100mbit/sec Ethernets that used hubs, not switches. And honestly there were never many 100BASE-TX hubs around; everyone went to switches around that time. The Gigabit Ethernet (1000BASE-T) spec requires switches; there's no such thing as a GigE hub. On modern switched Ethernets, you don't have a shared medium anymore. When you're plugged into a switch, the "collision domain" is only between you and your switch port. And if you're in full duplex mode, which is almost always true with switches, then you don't have any possibility of collision at all. If you can't have a collision, you'll never detect a collision, so you'll never have reason to transmit a jam signal. So back in the days of hubs (and shared cables like thinnet/cheapernet/10BASE-2 coax and thicknet 10BASE-5), here's how it worked: Imagine you h

Difference Between EEPROM and Flash

EEPROM vs Flash Flash is a very popular term when it comes to storage media as it is used by portable devices like phones, tablets, and media players. Flash actually is an offspring of EEPROM, which stands for Electrically Erasable Programmable Read-Only Memory. The main difference between EEPROM and Flash is the type of logic gates that they use. While EEPROM uses the faster NOR (a combination of Not and OR), Flash uses the slower NAND (Not and AND) type. The NOR type is a lot faster than the NAND type but there is the matter of affordability as the former is significantly more expensive than the NAND type. Another advantage of EEPROM over Flash is in how you can access and erase the stored data. EEPROM can access and erase the data byte-wise or a byte at a time. In comparison, Flash can only do so block-wise. In order to simplify the whole thing, individual bytes are grouped into a smaller number of blocks, which can have thousands of bytes in each block. This is a bit problema
