They are often widely distributed through mail ...
e. Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1][2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages. Programmers typically use high-level ...
Computer hardware. Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [1][2]

[1][2] Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. [3][4][5] This role contrasts with that ...
The two main categories of ECC codes are block codes and convolutional codes. Block codes work on fixed-size blocks (packets) of bits or symbols of predetermined size. Practical block codes can generally be hard-decoded in polynomial time to their block length. Convolutional codes work on bit or symbol streams of arbitrary length.
A software serial number, otherwise called a product key, is usually not embedded in the software but is assigned to a specific user with a right to use the software. The software will function only if a potential user enters a valid product code. The vast majority of possible codes are rejected by the software.
Graphical user interface elements are those elements used by graphical user interfaces (GUIs) to offer a consistent visual language to represent information stored in computers. These make it easier for people with few computer skills to work with and use computer software. This article explains the most common elements of visual language ...
