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.


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

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


Give power to motherboard.

  • 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 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.


  • 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)

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)


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

  • Primary
  • Extended
  • Logical


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

  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.



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


  • 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 was first introduce by IBM in 1983

Deployment type of OS


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


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).


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




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


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.
