To understand how code is executed on a computer, you must understand what makes a computer tick and how it can be manipulated. First, let's first talk about the fundamental ideas of computer hardware before progressing to the software side of things. What Is Binary? Binary is a base-2 n...
Now that you understand binary, you can see why the same numbers (powers of 2) appear when discussing it. Anytime you assign a number of bits for a value in computing, you have a finite number of options for it. Values that were chosen long ago due to limitations of the time, when ...
How does binary analysis work? Why is binary analysis important? What is Black Duck's solution for binary analysis? What to read next Definition Binary code is the fundamental form of the programming data that is directly interpreted by a computer. It’s composed of a string of 0s and ...
Most things in a computer are relatively simple to understand: the RAM, the storage, the peripherals, and the software all work together to make a computer function. But the heart of your system, the CPU, seems like magic even to many tech people. Here, we'll do our best to break it...
Machine code is submitted to a computer's processor in the form of binary files. The machine code files must target a specific computer platform, which refers to the combination of operating system and hardware architecture. For example, the binary machine code might target Windows and the Intel...
Numbers at Work in a Computer So, what does all this mean to the computer? The computer interprets combinations of binary numbers as text or instructions. For example, each lowercase and uppercase letter of the alphabet is assigned a different binary code. Each is also assigned a decimal rep...
Understanding Binary Numbers If you're interested in learning how to read binary, it's important to understand howbinary numberswork. Binary is known as a "base 2" numbering system, meaning there are two possible numbers for each digit; a one or a zero. Larger numbers are written by adding...
What types of Data does a computer understand? Computers only understand two types of data; binary code and character-based code. Binary code consists only of ones and zeros—which can be meaningful when put together in long, differentiated strings. Character-based code consists of letters, numbe...
An easy-to-understand introduction to computer memory, including an explanation of terms such as RAM, ROM, SDRAM, and DRAM.
But how does SMTP work? The "Simple" part of the name is pure truth in advertising. A message can be moved from one SMTP server to another using one of the simplest TCP/IP protocols (line-oriented telnet) and just a few simple text commands. One SMTP server makes a telnet-like connec...
