Q- What is a microprocessor?

- November 09, 2018

- Ans- 1. A microprocessor is a component that performs the instructions and tasks involved in computer processing. In a computer system, the microprocessor is the central unit that executes and manages the logical instructions passed to it. 2. A microprocessor may also be called a processor or central processing unit, but it is actually more advanced in terms of architectural design and is built over a silicon microchip. 3. A microprocessor is the most important unit within a computer system and is responsible for processing the unique set of instructions and processes. A microprocessor is designed to execute logical and computational tasks with typical operations such as addition/subtraction, interprocess and device communication, input/output management, etc. A microprocessor is composed of integrated circuits that hold thousands of transistors; exactly how many depends on its relative computing power. 4. Micropro

I/O Ports and Devices

- November 18, 2018

I/O Stands for "Input/Output" and is pronounced simply "eye-oh." Computers are based on the fundamental idea that every input results in an output. For example, if you are running a word processor program and type a sentence on your keyboard, the text will appear on the screen. The keyboard is an input device and the screen is an output device. You might also print the text using a printer, which is another output device. The computer's CPU handles all the I/O operations, sending the data it receives to the correct path. The path may be to the video card, to the hard drive, or to the RAM, just to name a few. The ports on the outside of a computer are commonly referred to as "I/O ports" because they are what connect input and output devices to the computer. Software developers use I/O to describe how a program will function, depending on what a user enters. For example, if the user presses the space bar key in a game, say " Super Jumper Man

BIOS

- November 18, 2018

Bios BIOS is short for Basic Input Output System . It is much more than the name suggests. One might think that BIOS controls input and output system. But the BIOS does much more, and it is not possible for any operating system to continue without a proper BIOS in place. Today, we will see what is BIOS in computers . BIOS has been there in our computers since the days of DOS – Disk Operating System… even before the structured DOS created by Microsoft. It is one of the most important components of the computer though it does not take the credit by appearing on your screen regularly. This post also looks at the most basic component of computers and explains why it is required in computers for computers to work. What is BIOS BIOS is a firmware, in short. It is stored on a chip on the part of the computer motherboard and is basically, a set of instructions that run to help load the operating system. You OS would fail to load, if not for the BIOS!

What is a Motherboard

- November 10, 2018

The mb , mainboard , mboard , mobo , mobd , backplane board , base board , main circuit board , planar board , system board , or a logic board on Apple computers. The motherboard is a printed circuit board that is the foundation of a computer, located on the back side or at the bottom of the computer chassis . It allocates power and allows communication to the CPU , RAM , and all other computer hardware components. Motherboard overview Below is a picture of the ASUS P5AD2-E motherboard with labels next to each of its major components. Clicking on the image directs you to a larger and more detailed version. Motherboard components Below are links to pages with more details for each of the motherboard components mentioned in the previous section. The links are listed in clockwise order starting from the top left-hand corner of the image. Components not labeled on the image above can be found in a section later in this document.

How to Install RAM

- November 10, 2018

video - How to instal RAM in PC In this Article: Installing Desktop RAM Installing Notebook RAM Community Q&A Has your computer started to feel a little sluggish? Maybe it’s not performing like it used to, or can’t keep up with the latest software? Upgrading your RAM (Random Access Memory) is one of the simplest and cheapest ways to quickly improve your computer’s performance. RAM can be upgraded on virtually any computer, and only takes a screwdriver and a few minutes. Read on after the jump to learn how. Installing Desktop RAM 1 . Find out what type of RAM is required for your desktop computer. RAM comes in a variety of models and speeds. The type of RAM you can get is dependent on your computer’s motherboard. Check your motherboard or computer’s documentation, or check the manufacturer’s website for the RAM specifications that are compatible with your hardware. RAM is available as DDR (double data rate), DDR2, DDR3,

Switched-Mode Power Supply (SMPS)

- November 12, 2018

A switched-mode power supply (SMPS) is an electronic circuit that converts power using switching devices that are turned on and off at high frequencies, and storage components such as inductors or capacitors to supply power when the switching device is in its non-conduction state. Switching power supplies have high efficiency and are widely used in a variety of electronic equipment, including computers and other sensitive equipment requiring stable and efficient power supply. A switched-mode power supply is also known as a switch-mode power supply or switching-mode power supply. Switched-mode power supplies are classified according to the type of input and output voltages. The four major categories are: AC to DC DC to DC DC to AC AC to AC A basic isolated AC to DC switched-mode power supply consists of: Input rectifier and filter Inverter consisting of switching devices such as MOSFETs Transformer Output rectifier and filter Feedbac

Computer Networks

- April 06, 2017

One way to categorize the different types of computer network designs is by their scope or scale. For historical reasons, the networking industry refers to nearly every type of design as some kind of area network . Common types of area networks are: 1. LAN - Local Area Network 2. WAN - Wide Area Network 3. WLAN - Wireless Local Area Network 4.MAN - Metropolitan Area Network 5. SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network 6. CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network 7.PAN - Personal Area Network LAN and WAN are the two primary and best-known categories of area networks, while the others have emerged with technology advances Note that network types differ from network topologies (such as bus, ring and star). (See also - Introduction to Network Topologies.) LAN: Local Area Network A LAN connects network devices

Memory

- November 09, 2018

Memory is the ability to take in information, store it, and recall it at a later time. In psychology, memory is broken into three stages: encoding, storage, and retrieval. Stages of memory : The three stages of memory : encoding, storage, and retrieval. Problems can occur at any stage of the process. Q- What is a memory? Ans- Computer memory is any physical device capable of storing information temporarily or permanently. For example, Random Access Memory ( RAM ), is a volatile memory that stores information on an integrated circuit used by the operating system, software, and hardware. Q- What are the 3 types of memory? Ans- I n this section we will consider the two types of memory , explicit memory and implicit memory , and then the three major memory stages: sensory, short-term, and long-term . Explicit Memory When we assess memory by asking a person to consciously remember things, we are mea

Types of computer memory (RAM and ROM)

- November 09, 2018

Memory is the best essential element of a computer because computer can’t perform simple tasks. Computer memory is of two basic type – Primary memory / Volatile memory and Secondary memory / non-volatile memory. Random Access Memory (RAM) is volatile memory and Read Only Memory (ROM) is non-volatile memory. 1. Random Access Memory (RAM) – It is also called as read write memory or the main memory or the primary memory . The programs and data that the CPU requires during execution of a program are stored in this memory. It is a volatile memory as the data loses when the power is turned off. RAM is further classified into two types- SRAM (Static Random Access Memory) and DRAM (Dynamic Random Access Memory) . 2. Read Only Memory (ROM) – Stores crucial information essential to operate the system, like the program essential to boot the computer. It is not volatile. Always retains its data. Used in embedded systems or where the programming needs no chang
