What is a Printer? Discuss the different types of impact and Non-impact Printers. ❃What is a Printer: A printer is a vital hardware output device to produce hard copies and print any valuable document . A document can be of any type, such as a text, image, or combination. It accepts input commands by users to print documents.

 Block diagram of Computer System  👉A block diagram of a computer shows a structural view of a computer system . The block diagram provides you a quick overview of the basic working process of a computer from inputting the data to getting the desired result as output. The diagram below shows a block diagram of the computer system :-

  Number System in Computers   👉As we all know, every computer is designed to store information such as - numbers, letters, and other special characters in coded form. So, here comes the need to have a basic understanding of the Number System in Computers . So, there are two types of Number systems - positional and non-positional. At first, we will discuss what a non-positional number system is? Later on, we will talk about the positional number system in computers. Non-positional Number systems In a non-positional number system, each symbol represents the same value regardless of its position in the number . To find the value of a number, one has to count the number of symbols present in the number. It is  tough to perform arithmetic with such a number system. This system has symbols such as I for 1, II for 2, III for 3, IIII for 4, IIIII for 5, etc. Positional Number systems In a positional number system, there are only a few symbols called digits . These symbols repr...

Microprocessors | SparkEasy 👉A control unit of a microcomputer - built on a single Integrated circuit, capable of performing arithmetic and logical operation and helps computers to communicate with other devices connected to it, is known as Microprocessor . It contains ALU, Control Unit, and a Register Array. Here, Arithmetic Logic Unit - performs arithmetic and logical operations on the data, which is received from an input device or memory of a computer system. Similarly, Control Unit - controls the flow of data and instructions, and Register Array - contains registers identified by letters like B, C, D, E, H, L, and accumulator. The first commercially launched microprocessor/first-generation microprocessor - the Intel 4004 , was a 4-bit microprocessor . A 4-bit broad memory location is usually called a - nibble. The Intel 4004 microprocessor's instruction set contained only 45 instructions. It weighed much less than an ounce . Intel 4004 was slow compared to the 30-ton ENIAC...

 Central Processing Unit  👉CPU is the brain of a computer system . It performs all major calculations and comparisons and activates and controls the operations of other units of the computer system. To evaluate a computer’s capabilities quickly, it is important to know how CPUs are internally structured, how different CPUs differ from each other, and how to evaluate CPU speed. These and other related concepts are described below.
