by Sudip M. Sawant, posted in Computer

zjhl2lgef9cyrql0jfa7kzbw2vucrb5knhfe1td9oxde9g5shnn1i-bv9ettdv9dsbugw0py
BIOS (Basic Input Output System)

  • BIOS is the program a computer’s microprocessor uses to get the computer system started after you turn it on.

  • It also manages data flow between the computer’s operating system and attached devices such as the hard disk, graphic card, keyboard, mouse and printer.

  • BIOS is a chip located on all motherboard that contain instruction of how your system should boot and how it operate.

  • The BIOS include instruction on how to load basic computer hardware & include a test referred as a POST that verifies the computer needs requirement to boot up properly.

  • If the computer does not pass the POST, you will receive a combination of beep indication that indicates malfunctioning within the computer.

 

POST:

  • POST is a test the computer must complete to verify all hardware is working properly before starting the remainder of the boot process.

  • If the computer passes the POST the computer will often return a single beep and if unsuccessful will create a beep code that indicates the error.

 

What do you meant by the term ROM BIOS (Read Only Memory BIOS)?

  • Read only means that the Program and data can only be read from it. Therefore Program and data cannot be written to it.

  • Most Computer contain small amount of ROM to stores programs that enable the computer to boots.

  • It is a non- volatile memory and hence it is referred as a permanent data storage area.

  • The BIOS in a PC is stored on a ROM chip located on the motherboard.

  • Early PCs used a ROM BIOS, but PCs today use a flash memory BIOS because it can be updated in place.

  • In order to update a ROM BIOS, the computer case had to be opened, and the ROM chip had to be located and replaced.

 

How do I get to BIOS in Windows 7?

  • Turn off the computer and wait five seconds.

  • Now turn on the computer and immediately press the F10 key or F1 key  three to four times after you see company logo on display until a BIOS Setup screen opens.
  • In the BIOS Setup utility, do one of the following: On the Main tab, find the BIOS version.

Note: – Different Company models Had Different Keys to go in Bios Screen Option.

 

What do mean by Dual BIOS?

  • Dual BIOS mean there are two ROM Bios IC Chip present on the Motherboard.

  • A dual BIOS is a computer motherboard that contains a main BIOS and a backup BIOS.

  • This type of setup can help a motherboard recover from any problems encountered during a BIOS update.

  • It also helps protect the BIOS from any potential virus, or any other data corruption that might occur.

View BIOS information at POST

hf

  • The first way is by restarting your computer.
  • When the initial load (also called POST) screen is displayed, the BIOS Type and version is also displayed.
    Tip: If the load screen is displayed for only a few seconds, you can try pressing the Pause/Break key on your keyboard to pause the loading process.
  • The BIOS information is typically found at or near the top of the POST screen.
  • Also, you will see information on what hard drive(s) and CD/DVD drives are installed in your computer.

 

Through Windows System Information

fhg

  • The BIOS information is also shown through the Windows System Information.
  • To open this tool click start, Programs, Accessories, System Tools, and then System Information.
  • If you’re running Windows Vista or Windows 7, type System Information in the Start search box.
  • In the System Information window, displaying information about your computer, including the type of BIOS you have and the version, under the System Summary section.
  • As can be seen in the picture below, this computer has a DELL BIOS version 1.0.0 with a Date of 11/5/2008.

 

Windows Registry


iuy

  • You can also find BIOS information in the Windows System Registry.

  • While in the registry realize that improperly changing a setting can affect how Windows operates.

  • To access the System Registry, click start and in the Run or Search box type reg edit in the text field and press enter. In the Windows Registry navigate to the below Registry directory.
    Hkey_local_machine\hardware\description\system

  • Find the sub keys System Bios Date and System Bios Version to see the BIOS and version for your motherboard. As can be seen in the picture below, the BIOS date and version are shown in these two keys.

 

Types of BIOS: –

  • Single Page BIOS.
  • Multi Page BIOS/ Five Page BIOS.
  • Explorer BIOS.
  • Phoenix BIOS.
  • UEFI BIOS (Unified Extensible Firmware Interface).

 

  1. Single Page BIOS: –

  • In Single Page Mode BIOS all the Option are in one single Page.

Hard disk & its types

by Sudip M. Sawant, posted in Computer, Uncategorized

Hard disk

 

  • Hard disk is a rigid non-removable magnetic disk with a large data storage capacity.
  • The hard drive is the computer’s main storage media device that permanently stores all data on the computer.
  • The hard drive was first introduced on September 13, 1956 and consists of one or more hard drive platters inside of air sealed casing.
  • Most computer hard drives are in an internal drive bay at the front of the computer and connect to the motherboard using either ata, scsi, or a sata cable and power cable.

 

Types of Hard disk

  1. IDE (Integrated Device Electronic) or ATA (advance technology attachment).
  2. SATA (serial advanced technology attachment).
  3. SCSI (small computer system interface).
  4. External Hard Drive.
  1. IDE (Integrated Device Electronic) or ATA (Advance Technology Attachment) :
  • IDE is a standard electronic interface used between a computer motherboard’s data paths or bus and the computer’s disk storage devices.
  • The IDE interface is based on the IBM PC Industry Standard Architecture (ISA) 16-bit bus standard, but it is also used in computers that use other bus standards.
  • Most computers which are sold recently, uses an enhanced version of IDE called Enhanced Integrated Drive Electronics (EIDE).
  • We can connect maximum two hard disk to a single controller, or one hard disk and one DVD Drive to a single controller.
  • Speed of IDE hard disk is 100 MB per second.
  • We have to perform Jumper Setting on Hard disk or IDE Optical Drive for connecting two or more Hard disk or Optical Drive.

 

 


Setting as a Master:

  • Use this setting if you are installing an additional hard disk drive to a single IDE cable with a hard disk drive Set as Slave, jumper one hard disk drive to Set as Master, and the other to set as Slave. 
  • Use this setting if you are installing an additional hard disk drive to a single IDE cable and the Cable Select setting is not recognized.

       Set as Slave:

  • Use this setting if you are installing an additional hard disk drive to a single IDE cable with a hard disk drive Set as Master, jumper one hard disk drive to Set as Master, and the other to set as Slave. 
  • Use this setting if you are installing an additional hard disk drive to a single IDE cable and the Cable Select setting is not recognized.

       Cable Select:

  • This setting is the default setting for pata / ide hard disk drives. 
  • With the Cable Select jumper setting, the BIOS determines whether a hard disk drive is Set as Master or Set as Slave by its position on the IDE cable. 
  • If the hard disk drive jumper is set to Cable Select and is connected to the black connector on the end of the IDE cable, it is recognized as Set as Master for that pata controller. 
  • If the hard disk drive jumper is set to Cable Select and is connected to the grey connector on the middle of the IDE cable, it is recognized as Set as Slave for that pata controller.

Note: When using Cable Select, your system must meet the following conditions:

  • Your systems host controller must support Cable Select.
  • Your hard drives must support Cable Select.
  • Your cable must support Cable Select.

 

  1. SATA (Serial Advance Technology Attachment): 

ewfg

  • Serial Advanced Technology Attachment, often abbreviated SATA , is a serial link – a single cable with a minimum of four wires creates a point-to-point connection between devices.
  • One of the main advantages of Serial ATA is that the thinner serial cables facilitate more efficient airflow inside a form factor and also allow for smaller chassis designs.
  • As an evolution of the older Parallel ATA physical storage interface, SATA host-adapters and devices communicate via a high-speed serial cable.
  • Several advantages over the older interface: reduced cable size and cost, native hot swapping, faster data transfer through higher signaling rates.
  • We can connect n number of sata hard disk or Optical drive depends upon the number of sata port available on the motherboard.
  • Sata data connector has 7 pins whereas Sata power connector has 15 pins.

  2. Sata 3.0 6 Gbit/s
  3. Sata 2.0 3 gbit/s
  4. Sata 1.0 5 Gbit/s

3. SCSI (Small Computer System Interface)

 

rger

  • Small Computer System Interface is a set of standards for physically connecting and transferring data between computers and peripheral devices.
  • SCSI is capable of supporting eight devices, or sixteen devices with Wide SCSI.
  • SCSI is a standard for parallel interfaces that transfers information at a rate of eight bits per second and faster, which is faster than the average parallel interface.
  • SCSI-2 and above supports up to seven peripheral devices, such as a hard drive, CD-ROM, and scanner, that can attach to a single SCSI port on a system’s bus.

 

  1. External Hard Disk. 

 

 

  • External HDD typically connect via USB; variants using USB 2.0 and Others interface generally have slower data transfer rates when compared to internally mounted hard drives connected through SATA.
  • Plug and play drive functionality offers system compatibility and features large storage options and portable design.
  • External HDDs are usually available as pre-assembled integrated products, but may be also assembled by combining an external enclosure (with USB or other interface) with a separately purchased HDD.
  • They are available in 2.5-inch and 3.5-inch sizes; 2.5-inch variants are typically called portable external drives, while 3.5-inch variants are referred to as desktop external drives.

Network and its Types

by Sudip M. Sawant, posted in Computer, Laptop
  • Network:

A computer network or data network is a telecommunications network that allows computers to exchange data.

In computer networks, networked computing devices pass data to each other along data connections.

The connections (network links) between nodes are established using either cable media or wireless media.

The best-known computer network is the Internet.

 

  • Internetwork:

Internetworking is the practice of connecting a computer network with other networks through the use of gateways that provide a common method of routing information packets between the networks.

The resulting system of interconnected networks is called an internetwork, or simply an internet.

Internetworking is a combination of the words inter (“between”) and networking; not internet-working or international-network.

 

  • Intra Network:

An intranet is a computer network that uses Internet Protocol technology to share information, operational systems, or computing services within an organization.

This term is used in contrast to extranet, a network between organizations, and instead refers to a network within an organization.

Sometimes, the term refers only to the organization’s internal website, but may be a more extensive part of the organization’s information technology infrastructure, and may be composed of multiple local area networks.

The objective is to organize each individual’s desktop with minimal cost, time and effort to be more productive, cost efficient, timely, and competitive.

 

  • Extranet:

An extranet is a computer network that allows controlled access from the outside, for specific business or educational purposes.

In a business-to-business context, an extranet can be viewed as an extension of an organization’s intranet that is extended to users outside the organization, usually partners, vendors and suppliers, in isolation from all other Internet users.

In contrast, business-to-consumer (B2C) models involve known servers of one or more companies, communicating with previously unknown consumer users.

 An extranet is similar to a DMZ in that it provides access to needed services for channel partners, without granting access to an organization’s entire network.

 

 

  • Topology:

Topology means structure of Network.

Types of Networks:

  1. Single Node Topology

network-topologies-5-728

2. Bus Topology

bus-topology

  • Easiest network topology for connecting computers or peripherals in a linear fashion.
  • Requires less cable length than a star topology.
  • It works well when you have a small network.

    3. Ring Topology

    single-ring-topology

  • A network server is not needed to control network connectivity between each workstation.
  • All data flows in one direction, reducing the chance of packet collisions.
  • Data can transfer between workstations at high speeds.
  • Additional workstations can be added without impacting performance of the network.
  1. Star Topology

    220px-star_topology

  • As compared to Bus topology it gives far much better performance, signals don’t necessarily get transmitted to all the workstations. A sent signal reaches the intended destination after passing through no more than 3-4 devices and 2-3 links.
  • Performance of the network is dependent on the capacity of central hub.
  • Easy to connect new nodes or devices. In star topology new nodes can be added easily without affecting rest of the network. Similarly components can also be removed easily.
  •  Centralized management. It helps in monitoring the network.
     Failure of one node or link doesn’t affect the rest of network. At the same time its easy to detect the failure and troubleshoot it.

 

  1. Mesh Topology

    mesh-topology

    1) Data can be transmitted from different devices simultaneously. This topology can withstand high traffic.
    2) Even if one of the components fails there is always an alternative present. So data transfer doesn’t get affected.
    3) Expansion and modification in topology can be done without disrupting other nodes.

 

  1. Hybrid Topology

    index

  • Hybrid, as the name suggests, is mixture of two different things.
  • Similarly in this type of topology we integrate two or more different topologies to form a resultant topology which has good points(as well as weaknesses) of all the constituent basic topologies rather than having characteristics of one specific topology.
  • This combination of topologies is done according to the requirements of the organization.

 

  1. Tree Topology

    248198418

  • A tree topology is a special type of structure in which many connected elements are arranged like the branches of a tree. For example, tree topologies are frequently used to organize the computers in a corporate network, or the information in a database.
  • In a tree topology, there can be only one connection between any two connected nodes. Because any two nodes can have only one mutual connection, tree topologies form a natural parent-child hierarchy.

 

  • Network Device:

Equipment’s that connect directly to a network segment is referred to a device.

These devices are broken up into two classification:

  1. End-User Device

These are the device that include computer, printer, scanner, and other device that provides service directly to user.

 

  1. Network Device

These are the device that include all device that connects end-user device together to allow them to communicate.

What is COMPUTER ?

by Sudip M. Sawant, posted in Uncategorized

Computer is an electronic device that is designed to work with Information.

The term computer is derived from the Latin term ‘computare’, this means to calculate or programmable machine.

Computer cannot do anything without a Program. It represents the decimal numbers through a string of binary digits.

Charles Babbage is called the “Grand Father” of the computer. The First mechanical computer designed by Charles Babbage was called Analytical Engine. It uses read-only memory in the form of punch cards.

Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculations.

In simple word, Computer is an Electronic device that automatically performs arithmetic or logic operation on information input, process that input and provides an output according to the performed set of instruction stored with it.

Concept of Computer

Hardware, Software and Firmware together makeup a Computer System.

Hardware: – Hardware describe all the physical components used for the assembly the
Computer System.

Software: – Software constitute the instruction on which the Computer act which thus makes the
Computer usable.

Firmware: – Firmware are programs that are permanently written and stored in computer
memory (ROM).
Types of Computer:

Computer are of four types namely.

1. Super Computer
2.Main Frame Computer
3. Mini Computer
4. Micro Computer.


A) Super Computer

Super Computer are the most powerful type of Computer.

They are used for high speed processing of data.

The only disadvantage of Super Computer is it generates large amount of heat so we
require cooling device for it.

The supercomputers are very expensive and very large in size. It can be accommodated in large air-conditioned rooms; some super computers can span an entire building.

Presently, China’s “Tianhe – 2” is the world’s faster Supercomputer.

The Tianhe – 2 can perform 100 Peta-flops, i.e. quadrillions of floating point operations per second.

Uses of Supercomputers

  • Space Exploration.
  • Earthquake studies.
  • Weather Forecasting.
  • Nuclear Weapon testing.

Popular Supercomputers

  • IBM’s Sequoia, in United States
  • Fujitsu’s K Computer in Japan
  • IBM’s Mira in United States
  • IBM’s SuperMUC in Germany
  •  NUDT Tianhe-1A in China

B) Main Frame Computer
Main Frame Computer are not as powerful as Super Computer, but they are capable
of great processing speeds and data storage.

Government organizations uses Mainframes to run their business operations.

The Mainframe computers can be accommodated in large air-conditioned rooms because of its size.

Super-computers are the fastest computers with large data storage capacity, Mainframes can also process & store large amount of data.

Banks educational institutions & insurance companies use mainframe computers to store data about their customers, students & insurance policy holders.


Popular Mainframe computers

  • Fujitsu’s ICL VME
  • Hitachi’s Z800

C) Mini Computer

Mini Computer is also known as Mid-range Computer, are refrigerator – sized
machines.

These are small machines and can be accommodated on a disk with not as processing and data storage capabilities as super-computers & Mainframes.

These computers are not designed for a single user. Individual departments of a large company or organizations use Mini-computers for specific purposes.

Medium- sized companies or Department of large Companies typically use them for specific purpose.

For e.g.: Production Department use Mini Computer to monitor certain manufacturing

process and assembly line operation.

Popular Minicomputers

  • K-202
  • Texas Instrument TI-990
  • SDS-92
  • IBM Mid-range computers

D) Micro Computer

Micro Computer are the least powerful and yet the most widely used and fastest
growing type of computer.

The Micro-computers are specially designed for general usage like entertainment, education and work purposes.

Well known manufacturers of Micro-computer are Dell, Apple, Samsung, Sony and Toshiba.

There are 4 types of Micro Computer namely. 1. Desktop 2. Notebook 3. Tablet PC
4. Handheld Computer.

1. Desktop:
Desktop PC are small enough to fit on top of or alongside a desk yet are too big to
carry around.

2. Notebook:
Notebook PC also known as Laptop PC.

They are Portable, Lightweight and fit into most briefcases.

3. Tablet PC:
Tablet PC is a type of Notebook Computer that accept your handwriting.

This input is digitized and converted to standard text that can be further processed by
program such as word processor.
