What is Computer Hardware

Computer hardware includes the physical, tangible parts or components of a computer, such as the cabinet, central processing unit, monitor, keyboard, computer data storage, graphic card, sound card, speakers and motherboard.

By contrast, software is instructions that can be stored and run by hardware.

Hardware is so-termed because it is “hard” or rigid with respect to changes or modifications; whereas software is “soft” because it is easy to update or change.

What is  SMPS-

Switched Mode Power Supply. They convert AC power into DC power and decide which h/w component need how much current.

Power connector types of SMPS

  • AT (6+6=12 pins)
  • ATX (20 pins)
  • BTX (24 – 28 pins)

If SMPS is not working take black and green wire and connect it It fan rotate it is Ok , If fan is not rotate the problem in SMPS.

MOLEX CONNECTOR

4 Pin peripheral power connector. Power to many devices in the computer.

Example:- Storage device, optical drive, fan, other peripherals

ATX

Give power to motherboard.

 RAM:- (Random Access Memory)- It is a volatile memory, it temporary store the data. In order for a program to run, it needs to be loaded into RAM first.

DYNAMIC RAM:-

  • Contains capacitors
  • Capacitors have to be refreshed with electricity constantly Capacitor (0 and 1)

DRAM stores each bit of data as program code in a storage cell consisting of a capacitor. A DRAM storage cell is dynamic is that it need to be refreshed or given a new electronic charge every few milliseconds to compensate for charge leaks the capacitor.

STATIC RAM

Static Ram is a type of RAM that holds data in a static forms, that is as long as the memory has power unlike dynamic RAM, it does not need to be refreshed.

DRAM V/S STATIC RAM

  • Static Ram is used in catch memory
  • Dynamic Ram is used in main memory.
  • SRAM is fast
  • DRAM is slow

Architecture of RAM

  • SIMM (Single in Line Memory Module)

32 bit data path

  • DIMM (dual in-line memory module)

Transfer 64 bits of data at a time.

  • RDIMM (Registered DIMM)

DIMM with improve reliability.

  • DDR (Dual Data Rate)

Sends double the amount of data in each cbck signal. It has 184 pins.

  • DDR2

It is faster than DDR because it allows for higer bus speeds. Use less power compare to DDR. It has 240 pins.

  • DDR3

Twice fast comparison DDR2. Use less power then DDR2.It has 240 pin.

  • DDR4

Use less power then DDR3. It has 288 pin.Process higher speed than DDR3.Use less power.

ROM:-

  • Bios and booting module is stored in ROM.(Read Only Memory) – It is a Non-volatile memory. Data in ROM is permanently return and is not erased when you power off your computer

 What is  SOCKET

Physical connection b/w motherboard and Processor. (where processor fit) responsible for transmitting energy to the Processor

Types

  • LPA (LAND GRID ARRAY)
  • PGA (PIN GRID ARRAY)

CORE

Responsible for processing speed. More core processor has more function simultaneously performed without overloading you system.

MULTI THREADING

It is double the no. Of core of processing.

PCI Slot (Peripheral Component Interconnect) –

  • PCI – big size
  • PCI express x16, x1

                  In 2004 new version PCI express PCI express slot is very fast compare PCI slot.

MEMORY

Memory is device where the data temporary of permanently store. According to storage there are two types of memory

HARD DISK

Hard Disk is magnetic storage device it is also Secondary Memory data permanently store on the HDD.

  • SATA (Serial ATA) –7PINS
  • PATA , ATA (Parallel Advanced Technology Attachment)– 40 PINS
  • SCSI (Small Computer System Interface)– (60-80 PINS)
  • SSD (SOLID STATE DRIVES)

WHAT IS PARTITION 

When logical divided of track is called partition. There are three types of partition.

  • Primary
  • Extended
  • Logical

HEAT SINK

It is absorbed the unwanted heat of CPU and throw throw it out through fan.

 SOUTH BRIDGE

North Bridge

CPU PORTS—

  1. PS2 PORT– USE FOR CONNECT KEYBOARD AND MOUSE

          Purple– keyboard            Green– Mouse

  1. USB Port– 2.0, 3.0, 3.1-latest
  2. Lan Port Or NIC Card– to connect to ethernet cable.
  3. Audio port– MIC — Pink

         Headphone– Green

          Audio out — Blue

  1. VGA Port– To connect display to cpu. 9pins
  2. HDMI port– high display multimedia interface

         Used for to watch HD video in display.

  1. DVI Port– Support digital signal

         If we use DVI port for display, we have to external audio port for audio as it only support video.

        Expension slot—To add extra ports to cpu

       Parrallel advanced Technology Attachment

       40 pin

       Data transmission is parallel

BIOS (Basic Input Output System) – The information all hardware ports (I/O) are store. In BIOS chip, BIOS first check all hardware path if all ports are working then start the PC and No any device found it give error.

2.UEFI

CMOS Battery – CMOS(Complementary Metal-oxide Semiconductor)

Battery provide a power supply of BIOS chip to maintain date and time.

It have two size

CACHE MEMORY – Self memory of processor is called cache memory there are three types of cache memory

PARTITON OF HARD DISK

  • MBR (Master Boot Record ) – The area of hard disk which is used to detect BIOS and start the booting process of HDD(Track 0, Sector 0, Cylinder 0)
  • GPT (GUID Partition Table)(Globally Unique Identify) – It is same of MBR. All Morden PC Operating System Support GPT including MAC OS and Windows OS.
MBR GPT
•      MBR was first introduce by IBM in 1983

•      It use MBR the capacity of one partition in 2 TB

•       MBR support maximum 4 Primary Partition.

•      GPT was latest and introduce by MICROSOFT.

•      GPT use unlimited spaces

Deployment type of OS

  • COS (CLIENT OPERATING SYSTEM)

The Client Operating System is the system that works within computer desktops and various portable devices. This system is different from centralized servers because it only supports a single user. Smartphones and small computer devices are able to support client operating systems

  • NOS-(NETWORK OPERATING SYSTEM)

A network operating system (NOS) is a computer operating system system that is designed primarily to support workstation, personal computer, and, in some instances, older terminal that are connected on a local area network (LAN).

  • SOS –(SERVER OPERATING SYSTEM)

A server operating system (OS) is a type of operating system that is designed to be installed and used on a server computer. It is an advanced version of an operating system, having features and capabilities required within a client-server architecture or similar enterprise computing environment.

DNS (Domain Name Server)

  • Type ipconfig /flushdns and press Enter.
  • Type ipconfig /registerdns and press Enter.
  • Type ipconfig /release and press Enter.
  • Type ipconfig /renew and press Enter.
  • Type ipconfig /displaydns and press Enter.

Dns cache

DNS cache (sometimes called a DNS resolver cache) is a temporary database, maintained by a computer’s operating system, that contains records of all the recent visits and attempted visits to websites and other internet domains.

SAM(Security Account Manager)

The Security Account Manager (SAM), often Security Accounts Manager, is a database file in Windows XP, Windows Vista, Windows 7, 8.1 and 10 that stores users’ passwords. It can be used to authenticate local and remote users. Beginning with Windows 2000 SP4, Active Directory authenticates remote users

C:\Windows\System32\config

C:\windows\system32\config\SAM

Encryption

The translation of data into a secret code. Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Unencrypted data is called plain text; encrypted data is referred to as cipher text.

  • AES. The Advanced Encryption Standard,
  • Triple Data Encryption Standard
  • Rivest Shamir Adleman

NAS

Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. NAS is specialized for serving files either by its hardware, software, or configuration.

  1. I was very happy to seek out this internet-site.I wanted to thanks to your time for this glorious learn!! I undoubtedly having fun with each little little bit of it and I have you bookmarked to take a look at new stuff you weblog post.

  2. I do like the way you have presented this particular problem plus it does indeed present me personally a lot of fodder for thought. Nonetheless, from what precisely I have witnessed, I basically wish as the remarks pack on that men and women continue to be on point and don’t embark on a soap box involving some other news of the day. Still, thank you for this fantastic piece and while I do not concur with it in totality, I respect your point of view.
