COMPUTER FUNDAMENTALS
 A Computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.
 A general purpose computer has four main components: the arithmetic logic unit (ALU), the control unit, the memory, and the input and output devices (collectively termed I/O).
 The data that is fed into a computer processor received into the computer by a keyboard or other sources is called Input.
 A computer is an electronic device that accepts data from the user (input), processes the data by

performing calculations and operations on it and generates the desired Output.
The device which is used with a computer to display or store data is called Peripherals.
The mechanical, magnetic, electronic and electrical components that comprises a computer system such as the Central Processing Unit (CPU), monitor, keyboard, etc. is known as Hardware.
A set of instructions that tells the computer about the tasks to be performed and how these tasks are to performed, is known as Software.
An unprocessed collection or representation of raw facts represented in a manner suitable for communication, interpretation or processing by humans or by automatic means, is known as Data.

 The result of processing, manipulating and organising data in a way that adds to the knowledge of the person receiving it, is known as Information.
 The smallest unit of information, a computer can understand and process, is known as Bit.
 The primary goal of computer is to process information that it receives and output the results.
The process of control and alter information is known as Processing.
 The number system computer used to store data and perform calculation - Binary Number System.
 Computer Speed, Accuracy, Diligence, Storage
Capability, Automation, Remembrance Power and
Versatility are the main Characteristics of
Computer.
 Self Intelligence, Decision-Making power, Learning power, Self care, Feelings are the Limitations of
Computer.
 A mainframe computer is a much larger computer that typically fills a room and may cost many hundreds or thousands of times as much as a personal computer. They are designed to perform large numbers of calculations for governments and large enterprises.
 Read-only memory (ROM) is a storage medium used in computers and other electronic devices. Data stored in ROM can only be modified slowly or with difficulty, or not at all.
 ROM is non-volatile and the contents are retained even after the power is switched off.
 It only allows reading.
 The types of ROM include PROM, EPROM and
EEPROM.
 Random Access Memory (RAM),allows the computer to store data for immediate for immediate manipulation and to keep track of what is currently being processed.
 RAM is referred to as volatile memory and is lost when the power is turned off.
 It allows reading and writing.
 The two main types of RAM are static RAM and dynamic RAM.
 SRAM retains data as long as power is provided to the memory chip and need not be refreshed periodically. SRAM stands for Static Random Access
Memory.

 Primary memory is computer memory that a processor or computer accesses first or directly.
 For example: RAM, and Cache Memory.
 Secondary memory (or secondary storage) is the slowest and cheapest form of memory. It cannot be processed directly by the CPU.
 Secondary memory devices include magnetic disks like hard drives and floppy disks, optical disks such as CDs and CDROMs, and magnetic tapes, which were the first forms of secondary memory.
 Virtual memory is memory on the hard disk that the CPU uses as an extended RAM.
 Installation is the process of copying software programs from secondary storage media to the hard disk.  A central computer that holds collections of data and programs for many PCs, workstations and other computers is a Server.

 The data on DRAM continues to move in and out of the memory as long as power is available and must be continually refreshed to maintain the data. DRAM stands for Dynamic Random Access Memory.

 An Arithmetic Logic Unit (ALU) is a digital circuit

that performs integer arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit of a computer.

 Control Unit is responsible for controlling the overall operations of computer. It coordinates the sequence of execution of instructions and controls the overall functioning of the computer.
 The first computer architecture was introduced by
John Von Neumann (1970)
 Personal computers use a number of chips mounted

on a main circuit board called Motherboard.
 The CPU is fabricated as a single Integrated Circuit
(IC) chip. It is also known as the Microprocessor.

 Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system

to support more than one processor and/or the ability to allocate tasks between them.

 The organization and interconnection of the various components of a computer system is known as



which are generally laid out in the same style as in typewriters are known as Alphanumeric Keys.
 'Caps lock' and 'Num lock' keys are called as Toggle

Keys because when pressed, they change their status from one state to another. www.bankersadda.com | www.careerpower.in Numeric Keypad is a keypad located on the right hand side of the keyboard. It consists of digits and mathematical operators.
A Modifier key is a special key (or combination) on a computer keyboard that temporarily modifies the normal action of another key when pressed together.
By themselves, modifier keys usually do nothing; that is, pressing any of the Shift, Alt, or Ctrl keys alone does not (generally) trigger any action from the computer.
A Mouse is the most popular input device which is used today for interactive processing and for the one line entry of data for batch processing.
Drag and Drop refers to the action of clicking and holding down the mouse button, while moving the mouse and then releasing the mouse button.

INTERNET

 The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to link several billion devices worldwide.
 It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless, and optical networking technologies.  The World Wide Web (abbreviated as WWW or W3, commonly known as the Web) is a system of interlinked hypertext documents that are accessed via the Internet.
 A Website, is a set of related web pages served from a single web domain.
 A Home page, index page, or main page is a page on a website. A home page usually refers to:  The initial or main web page of a website, sometimes called the "front page" (by analogy with newspapers).

The first page that appears upon opening a web browser program, which is also sometimes called the start page. This 'start page' can be a website or it can be a page with various browser functions such as the visual display of websites that are often visited in the web browser.
 The web page or local file that automatically loads when a web browser starts or when the browser's "home" button is pressed; this is also called a "home page". The user can specify the URL of the page to be loaded, or alternatively choose e.g. to re-load the most recent web page browsed.
 A personal web page, for example at a web hosting service or a university web site, that typically is stored in the home directory of the user. A Hyperlink is a reference to data that the reader can directly follow either by clicking or by hovering or that is followed automatically
A web browser (commonly referred to as a browser) is a software application for retrieving, presenting and traversing information resources on the World Wide Web.
Some of the famous browsers are Safari, Chrome,
Firefox, Bolt, UC Browser and Internet Explorer
The Uniform Resource Locator, abbreviated as
URL is a specific character string that constitutes a reference to a resource. In most web browsers, the
URL of a web page is displayed on top inside an address bar.
(i) An example of a typical URL would be
"http://www.bankersadda.com".
Downloading means to receive data to a local system from a remote system, or to initiate such a data transfer
Uploading refers to the sending of data from a local system to a remote system such as a server or another client with the intent that the remote system should store a copy of the data being transferred An Internet Protocol address (also known as an
IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network. It acts as an identifier for a computer. It is a unique address for every computer. An email attachment is a computer file sent along with an email message. One or more files can be attached to any email message, and be sent along with it to the recipient.

 Hotmail was co - founded by an Indian American entrepreneur Sabeer Bhatia along with Jack Smith in July of 1996
 CC(Carbon Copy) in e – mail indicates those who are to receive a copy of a message addressed primarily to another. The list of CCed recipients is visible to all other recipients of the message.
 An additional BCC (blind carbon copy) field is available for hidden notification; recipients listed in the BCC field receive a copy of the message, but are not shown on any other recipient's copy (including other BCC recipients)
 The Drafts folder retains copies of messages that you have started but are not yet ready to send.
 The first email was sent by Ray Tomlinson to himself in 1971.

DATA COMMUNICATION & NETWORKING

 Data Communication deals with the transmission of digital data from one device to another. Data is transferred through a pathway called as communication channel which can be physical wire connecting the devices or may be unguided media like laser, microwave etc.
 A communication channel has a source or transmitter at one side and a designation or receiver at another side of the network. The source of data origination is single but there may be multiple receivers. A communication channel is of 3 types:  Simplex: In this, communication is unidirectional
i.e. one of the two devices can transmit the data and the other can only receive the data. For eg.
Radio broadcasting, television broadcasting etc.
 Half duplex:In this communication is bidirectional. Either of the devices can act as transmitter or receiver but only one device can transmit the data at one time. For eg. Walkie talkie.  Full Duplex: Here also communication is in both directions and both the devices can simultaneously transmit the data. For eg.
Telephone conversation.
 Different types of network are: LAN, MAN and
WAN.
 A LAN (local area network) is a group of computers and network devices connected together, usually within the same building. By definition, the connections must be high speed and relatively inexpensive (e.g., token ring or Ethernet).
 A MAN (metropolitan area network) is a larger network that usually spans several buildings in the same city or town.
 A WAN (wide area network), in comparison to a
MAN, is not restricted to a geographical location, www.careerpower.in | www.sscadda.com Page 15

although it might be confined within the bounds of a state or country. A WAN connects several LANs, and may be limited to an enterprise (a corporation or an organization) or accessible to the public. The technology is high speed and relatively expensive.
The Internet is an example of a worldwide public
WAN.

 bridge thus improving performance. It uses physical addresses of the packets for this decision. It works on Data Link Layer of the OSI model. A bridge uses
Spanning tree Algorithm for data transmission so as to avoid loops in the network.
 IPv4 - 32 bits
 IPv6 - 128 bits

Networking Devices

 Modem:
Modem
stands for ModulatorDemodulator. It is used to connect computers for communication via telephone lines.
 Hub: It works at the Physical layer. It just acts like a connector of several computers i.e. simply connects all the devices on its ports together. It broadcasts all the data packets arriving at it with no filtering capacity.
 Switch: It works at the Data Link Layer. It is used for dividing a network into segments called subnets.
It provides filtering of data packets and prevents network traffic also.
 Repeater: It operates at thePhysical Layer. It is used to amplify a signal that has lost its original strength so as to enable them to travel long distances. It can only join the networks that transmit similar data packets. It does not have filtering capacity i.e. all data including noise is amplified and passed on in the network so don’t help in reducing network traffic.
 Router: It works at the Network Layer and is used to connect different networks that have different architectures and protocols. It sends the data packets to desired destination by choosing the best path available thus reducing network traffic. It routes the data packets using the routing table that contains all the Information regarding all known network addresses, possible paths and cost of transmission over them. Availability of path and cost of transmission decide sending of data over that path. It is of 2 types: static (manual configuration of routing table is needed) and dynamic (automatically discovers paths).
 Gateway: It operates in all the layers of the network architecture. It can be used to connect two different networks having different architectures, environment and even models. It converts the data packets in form that is suitable to the destination application. The two different networks may differ in types of communication protocols they use, language, data formats etc.
 Bridge: They are used two connect two LANs with the same standard but using different types of cables. It provides an intelligent connection by allowing only desired messages to cross the

INFORMATION SECURITY
 A Computer Virus is a computer program or code that can replicate itself and spread from one computer system to another system. A computer virus has the capacity to corrupt or to delete data on your computer and it can utilize an e-mail program to spread the virus to other computer systems. In the worst case scenario, it can even delete everything on your hard disk. The purpose of it is to disrupt the operation of the computer or the program.  Some examples of Computer Virus are Trojan viruses. stealth viruses, worms, malware
(malicious software), Disk Killer, Stone virus,
Sunday, Cascade, Nuclear, Word Concept, etc.
 Malware, short for malicious software, is any software used to disrupt computer operation, gather sensitive information, or gain access to private computer systems. It can appear in the form of executable code, scripts, active content, and other software.  Antivirus Software is used to scan the hard disk to remove the virus from them. Some of the famous anti – viruses available are Avast!, Norton, Avira,
Kaspersky, AVG, etc.
 A person who uses his or her expertise to gain access to other people’s computers to get information illegally or do damage is a Hacker.

 Authorization is the function of specifying access rights to resources related to information security and computer security in general and to access control in particular. More formally, "to authorize" is to define an access policy.
 Authentication is the act of confirming the truth of an attribute of a single piece of data or entity. It might involve confirming the identity of a person by validating their identity documents, verifying the validity of a website with a digital certificate, tracing the age of an artifact by carbon dating, or ensuring that a product is what its packaging and labelling claim to be. In other words, Authentication often involves verifying the validity of at least one form of identification.
 Phishing is the attempt to acquire sensitive information such as usernames, passwords, and credit card details (and sometimes, indirectly, money) by masquerading as a trustworthy entity in an electronic communication.
 A Spoofing attack is a situation in which one person or program successfully represents oneself as another by falsifying data and thereby gaining an illegitimate advantage.
 The Open Systems Interconnection model (OSI) is a conceptual model that characterizes and standardizes the internal functions of a communication system by partitioning it into abstraction layers. The model is a product of the
Open Systems Interconnection project at the
International Organization for Standardization
(ISO).
Seven layers of OSI Model are:
 Application Layer
 Presentation Layer
 Session Layer
 Transport Layer
 Network Layer
 Data link Layer
 Physical Layer
 Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network.There are two basic categories of network topologies: 
Physical topologies and logical topologies.
Physical topology is the placement of the various components of a network, including device location and cable installation, while logical topology illustrates how data flows within a network, regardless of its physical design. Various types of topologies are:
 Bus Topology
 Star Topology

DATABASE MANAGEMENT SYSTEM
 DBMS is the acronym of Data Base Management
System. DBMS is a collection of interrelated data and a set of programs to access this data in a convenient and efficient way. It controls the organization, storage, retrieval, security and integrity of data in a database.
 Architecture of DBMS-The generalized architecture of DBMS is called ANSI/ SPARC model.
The architecture is divided into three levels:
 External view or user view/View Level- It is the highest level of data abstraction. This includes only those portions of database of concern to a user or
Application program. Each user has a different

www.bankersadda.com

|

external view and it is described by means of a scheme called external schema.
 Conceptual view/Logical Level- All the database entities and the relationship among them are included. One conceptual view represents the entire database called conceptual schema.
 Internal view/Physical Level- It is the lowest level of abstraction, closest to the physical storage method. It describes how the data is stored, what is the structure of data storage and the method of accessing these data. It is represented by internal schema.  Data model:A data model is a plan for building a database. The model represents data conceptually, the way the user sees it, rather than how computers

store it. Data models focus on required data elements and associations.
 Entity – Relationship Model
 Relational Model
 Entity:A thing (animate or inanimate) of independent physical or conceptual existence and distinguishable. In the University database context, an individual student, faculty member, a class room, a course are entities.
 Attributes
 Each entity is described by a set of attributes/properties. Types of Attributes

Simple Attributes: having atomic or indivisible values: Dept – a string Phone
Number – an eight digit number.

Composite Attributes: having several components in the value.
Example:
Qualification with components (Degree Name,
Year, University Name)

Derived Attributes: Attribute value is dependent on some other attribute. Example:
Age depends on Date of Birth. So age is a derived attribute.

Single-valued: having only one value rather than a set of values. For instance, Place of
Birth-single string value.

Multi-valued: having a set of values rather than a single value, for instance, Courses
Enrolled attribute for student Email Address attribute for student Previous Degree attribute for student. Attributes can be: simple singlevalued, simple multi-valued, composite singlevalued or composite multi-valued.
