Computer, any of a class of devices capable of solving problems by processing information in discrete form. It operates on data, including magnitudes, letters, and symbols, that are expressed in binary code — i.e., using only the two digits 0 and 1. By counting, comparing, and manipulating these digits or their combinations according to a set of instructions held in its memory, a digital computer can perform such tasks as to control industrial processes and regulate the operations of machines; analyze and organize vast amounts of business data; and simulate the behaviour of dynamic systems (e.g., global weather patterns and chemical reactions) in scientific research. A typical computer system has four basic functional elements : (1) Input-output equipment, (2) Main memory, (3) Control unit, and (4) Arithmetic-logic unit.

THE CENTRAL PROCESSING UNIT & OPERATING SYSTEMS

Santino Madut Uchalla

Subhash shetty

A computer is a device that can be instructed to carry out arbitrary sequences of arithmetic or logical operations automatically. The ability of computers to follow generalized sets of operations, called programs, enables them to perform an extremely wide range of tasks. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls , factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers. Since ancient times, simple manual devices like the abacus aided people in doing calculations. Early in the Industrial Revolution, some mechanical devices were built to automate long tedious tasks, such as guiding patterns for looms. More sophisticated electrical machines did specialized analog calculations in the early 20th century. The first digital electronic calculating machines were developed during World War II. The speed, power, and versatility of computers has increased continuously and dramatically since then. Conventionally, a modern computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logical operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices include input devices (keyboards, mice, joystick, etc.), output devices (monitor screens, printers, etc.), and input/output devices that perform both functions (e.g., the 2000s-era touchscreen). Peripheral devices allow information to be retrieved from an external source and they enable the result of operations to be saved and retrieved.- source = Wekipeda

The central processing unit (CPU, occasionally central processor unit) is the hardware within a computer system which carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system. The term has been in use in the computer industry at least since the early 1960s. The form, design, and implementation of CPUs have changed over the course of their history, but their fundamental operation remains much the same. A computer as shown below performs basically five major operations or functions irrespective of their size and make. These are 1) it accepts data or instructions by way of input, 2) it stores data, 3) it can process data as required by the user, 4) it gives results in the form of output, and 5) it controls all operations inside a computer. We discuss below each of these operations. 1. Input: In computing, an input device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or other information appliance. 2. Storage: Storage Devices are the data storage devices that are used in the computers to store the data. The computer has many types of data storage devices. Some of them can be classified as the removable data Storage Devices and the others as the non removable data Storage Devices. The memory is of two types; one is the primary memory and the other one is the secondary memory. The primary memory is the volatile memory and the secondary memory is the non volatile memory. The volatile memory is the kind of the memory that is erasable and the non volatile memory is the one where in the contents cannot be erased. Basically when we talk about the data storage devices it is generally assumed to be the secondary memory.

INTRODUCTION TO COMPUTER SOFTWARE

• A computer is a machine that takes instructions and performs computations based on those instructions.

CHARACTERISTICS OF COMPUTERS

GENERATION OF COMPUTERS

The word generation means the state of improvement in the product development process. Similarly, computer generation refers to the different advancements of new computer technology.

First Generation (1940-1956) Vacuum Tubes

The first generation computers used very large number of vacuum tubes for circuitry and magnetic drums for memory.

UNIVAC and ENIAC computers are prime examples of first-generation computing devices.

Advantages: Fastest calculating device of their time

Disadvantages:

1. Dissipate a lot of heat

2. Consume a lot of electricity

3. Very bulky in size

4. These computers were frequently down due to hardware failures.

5. These computers needed constant maintenance because of low mean time between failures

6. Limited commercial use because these computers were difficult to program

7. Very expensive

Second Generation (1956-1963) Transistors

• The second generation computers were manufactured using transistors.
• While first generation computers were programmed using machine language, second generation computers moved towards symbolic, or assembly languages, which allowed programmers to specify instructions in words.
• At this time, high-level programming languages like COBOL, FORTRAN, ALGOL and SNOBOL were also being developed.
• Second generation computers were first to store instructions in memory, which moved from a magnetic drum to magnetic core technology.
• Second generation computers were first developed for the atomic energy industry.

Advantages:

1. Consumed less electricity and thus dissipated less heat as compared to first generation computers

2. Faster, cheaper smaller and more reliable than first generation computers

3. Could be programmed using assembly language and high level languages

4. These computers had faster primary memory and a larger secondary memory

1. Second generation computers were manufactured using transistors that had to be assembled manually. This made commercial production of computers difficult and expensive.

Third Generation (1964-1971) Integrated Circuits

• The development of the integrated circuit was the hallmark of the third generation of computers.
• These computers had few megabytes of main memory and magnetic disks which could store few tens of megabytes of data per disk drive.
• High level programming languages like COBOL and FORTRAN were standardized by ANSI
• Some more high level programming languages like PL/I PASCAL and BASIC were introduced at this time.
• Third generation computers were the first to implement time sharing operating systems.
• Input to these computers could now be provided using keyboards and mouse.
• Faster than second generation computers and could perform 1 million transactions per second.

2. Smaller, cheaper and more reliable than their predecessors

3. These computers had faster and larger primary memory and secondary storage

4. They were widely used for scientific as well as business applications

5. During this generation of computers, standardization of existing high level languages and invention of new high level languages was done

6. These computers had time sharing operating system which allowed interactive use of computer by one or more users simultaneously thereby improving the productivity of the users.

Fourth Generation (1971-1989) Microprocessors

• The microprocessor started the fourth generation of computers with thousands of integrated circuits built onto a single silicon chip.
• Semi-conductor memories were used which were very fast, even the hard disks became cheaper, smaller in size and larger in capacity.
• For input, floppy disks (in addition to magnetic tapes) were used to port data and programs from one computer to another.
• During this period many new operating systems were developed like MS-DOS MS-Windows UNIX and Apple’s proprietary operating system.
• Development of GUIs, the mouse and handheld devices.
• In this period, several word processing packages, spreadsheet packages and graphics packages were introduced.

1. Smaller, cheaper, faster and more reliable

2. Consumed less electricity and therefore dissipated less heat

3. They had faster and larger primary memory and secondary storage

4. They could be used as general purpose computers.

5. GUIs enabled people to learn to work with computers very easily. So the use of computers in both office and home became widespread.

6. Networks allowed sharing of resources thereby efficient utilization of computer hardware and software

Fifth Generation (Present and Beyond) Artificial Intelligence

• The fifth generation computers are completely based on a new concept of artificial intelligence.
• Although such computers are still in development, there are certain applications like voice recognition which is widely being used today.
• In the fifth generation of computers the aim is to develop devices that respond to natural language input and are capable of learning and self-organization.
• The two most common are LISP and Prolog.

CLASSIFICATION OF COMPUTERS

Computers can be broadly classified into four categories based on their speed, amount of data that they can hold and price.

Information can be displayed using an electronic presentation application. This information is usually presented as a slide show — the data is displayed on a slide that may be viewed on a computer monitor or projected onto a screen using an LCD projector. A presentation might consist of multiple slides that are exhibited one after the other. The presentation tool in MS Office is MS PowerPoint. Microsoft PowerPoint is a popular presentation application, although there are alternatives such as Corel Presentations OpenOffice.org, Impress, etc. 

Three major components of a presentation program are: 

(i) An editor that allows text to be input and formatted  (ii) a means for inserting visual pictures, audio, and video  (iii) and a slide-show system to display the final content.

Introduction to Computer Network Dr. Rania R Ziedan

Agenda • Introduction • Network types • Network topology • Network connection models • OSI model

Computer network • A collection of computing devices that are connected in various ways in order to communicate and share resources or files • Wired network: the connections between computers in a network are made using physical wires or cables • Wireless network: the connections between computers in a network are made using radio waves or infrared signals

Computer network • Each computer in the network is known as: node or host • Data transfer rate: is the speed with which data is moved from one place on a network to another, which is a key feature in computer networks

Network Types • Local Area Network (LAN): two or more computers connected together, the computers are physically near each other (for example: in the same building) • LANs are inexpensive to install • LANs provide higher speeds

Network Types • Metropolitan Area Network (MAN): usually span tens of kilometers (for example: in the same city) • The cost of installation and operation is higher. • MANs use high-speed connections such as fiber optics to achieve higher speeds

Network Types • Wide Area Network (WAN): is a connection of LANs (for example : the Internet) • WANs span a larger area than a single city. • These use long distance telecommunication networks for connection, thereby increasing the cost.

The Internet • It is a large group of computers that are connected to each other and used to send information quickly between computers around the world

Physical topology of a network • The term physical topology refers to the way in which a network is laid out physically. • The topology of a network is the geometric representation of the relationship of all the links and linking devices • There are four basic topologies possible: mesh, star, bus, and ring

Physical topology of a network • Mesh Topology • In a mesh topology, every device has a dedicated point-to-point link to every other device. • The term dedicated means that the link carries traffic only between the two devices it connects. • The number of physical links in a fully connected mesh network with n nodes  n(n-1)/2 • The mesh topology used in the connection of telephone regionaloffices in which each regional office needs to be connected to every other regional office.

Physical topology of a network • Mesh Topology • Advantages: • Each link can carry its own data load, thus eliminating the traffic problems that can occur with shared links. • A mesh topology is robust. If one link becomes unusable, it does not incapacitate the entire system. • Every message travels along a dedicated line, only the intended recipient sees it. Physical boundaries prevent other users from gaining access to messages. • Point-to-point links make fault identification and fault isolation easy. Traffic can be routed to avoid links with suspected problems. • Disadvantage: • The amount of cabling and the number of I/O ports required.

Physical topology of a network • Star Topology • Each device has a dedicated point-to-point link only to a central controller, usually called a hub. • A star topology does not allow direct traffic between devices. • The controller acts as an exchange: If one device wants to send data to another, it sends the data to the controller, which then relays the data to the other connected device. • The star topology is used in local-area networks (LANs)

Physical topology of a network • Star Topology • Advantages: • less expensive than a mesh topology, each device needs only one link and one I/O port to connect it to any number of others. • Easy to install and reconfigure. • Robustness, if one link fails, only that link is affected, all other links remain active. • As long as the hub is working, it can be used to monitor link problems and bypass defective links • Disadvantage: • the dependency of the whole topology on one single point, the hub. If the hub goes down, the whole system is dead

Physical topology of a network • Bus Topology • A bus topology is multipoint connection. • One long cable acts as a backbone to link all the devices in a network. • Nodes are connected to the bus cable by drop lines and taps. • There is a limit on the number of taps a bus can support and on the distance between those taps. As a signal travels along the backbone, some of its energy is transformed into heat. Therefore, it becomes weaker and weaker as it travels farther and farther. • Bus topology was the one of the first topologies used in the design of early local area networks. • The cable has two end terminals that dampen the signal so that it does not keep moving from one end of the network to the other.

Physical topology of a network • Bus Topology • Advantages: • Ease of installation • Bus uses less cabling than mesh or star topologies. • Disadvantages: • Difficult reconnection and fault isolation. • Difficult to add new devices. • Signal reflection at the taps can cause degradation in quality. This degradation can be controlled by limiting the number and spacing of devices connected to a given length of cable. • Adding new devices may therefore require modification or replacement of the backbone. • In addition, a fault or break in the bus cable stops all transmission, even between devices on the same side of the problem. The damaged area reflects signals back in the direction of origin, creating noise in both directions.

Physical topology of a network • Ring Topology • Each device has a dedicated point-to-point connection with only the two devices on either side of it. • A signal is passed along the ring in one direction, from device to device, until it reaches its destination. • Each device in the ring incorporates a repeater. When a device receives a signal intended for another device, its repeater regenerates the bits and passes them along

Physical topology of a network • Ring Topology • Advantages: • easy to install and reconfigure • Fault isolation is simplified. • Generally in a ring, a signal is always circulating . If one device does not receive a signal within a specified period, it can issue an alarm. The alarm alerts the network operator to the problem and its location. • To add or delete a device requires changing only two connections. The only constraints are media and traffic considerations (maximum ring length and number of devices). • Disadvantages: • Unidirectional traffic • a break in the ring can disable the entire network. • This weakness can be solved by using a dual ring or a switch capable of closing off the break.

Network connection models • Networks can also be classified according to the roles that the networked computers play in the network’s operation. • Peer-to-peer, • server-based, • and client-based.

Network connection models Peer-to-peer model all computers are considered equal. Each computer controls its own information and is capable of functioning as either a client or a server depending upon the requirement. • Peer-to-peer networks are inexpensive and easy to install. • They are popular as home networks and for use in small companies. • Most operating systems come with built-in peer-to-peer networking capability. • The maximum number of peers that can operate on a peer-to-peer network is ten. • Each peer shares resources and allows others open access to them. • Shares can be document folders, printers, peripherals, and any other resource that they control on their computers.

Network connection models Peer-to-peer network

Network connection models • client-server model is a software that consists of two parts, client systems and server systems, both communicate over a computer network

Network connection models • The client-server relationship describes the relation between the client and how it makes a service request to the server, and how the server can accept these requests, process them, and return the requested information to the client

Page request How the Web Works? • WWW use classical client / server architecture • HTTP is text-based request-response protocol HTTP HTTP Server response Server running Web Server Software (IIS, Apache, etc.) Client running a Web Browser

Client/Server • There are two types of servers: • File serverA computer that stores and manages files for multiple users on a network • Web serverA computer that responds to requests for web pages (from the browser client)

Web servers and browsers • web server: software that listens for web page requests • Apache • Microsoft Internet Information Server (IIS) (part of Windows) • web browser: fetches/displays documents from web servers • Mozilla Firefox • Microsoft Internet Explorer (IE) • Apple Safari • Google Chrome • Opera

OSI Architecture The OSI 7-layer Model OSI – Open Systems Interconnection

Description of Layers • Physical Layer • Handles the transmission of raw bits over a communication link • Data Link Layer • Collects a stream of bits into a larger aggregate called a frame • Network adaptor and device drivers in OS implement the protocol in the datalink layer • Frames are actually delivered to hosts • Network Layer • Handles routing between nodes within a packet-switched network • Unit of data exchanged between nodes in this layer is called a packet The lower three layers are implemented on all network nodes

Description of Layers • Transport Layer • Implements a process-to-process channel • Unit of data exchanges in this layer is called a message • Session Layer • Provides a name space that is used to tie together the potentially different transport streams that are part of a single application • Presentation Layer • Concerned about the format of data exchanged between peers • Application Layer • Standardize common type of exchanges The transport layer and the higher layers typically run only on end-hosts and not on the intermediate switches and routers

Summary • A computer network consists of two or more computers that are connected and are able to communicate. • The basic purpose of networks is to enable effective communication, share resources, and facilitate centralized management of data. • Networks can be classified according to their geographical boundaries or their component roles. • The topology of a network is the geometric representation of the relationship of all the links and linking devices
