SECTOR OF SPECIFIC

1.Computer System - The complete computer made up of the CPU, memory and related electronics (main cabinet), all the peripheral devices connected to it and its operating system. Computer systems fall into two broad divisions: clients and servers. Client machines fall into three categories from low to high end: laptop, desktop and workstation. Servers range from small to large: low-end servers, midrange servers and mainframes.

2.Computer Network, or simply a Network, is a collection of computers and other hardware interconnected by communication channels that allow sharing of resources and information. Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device, then two devices are said to be in a network. It is a group of devices connected to each other. Networks may be classified into a wide variety of characteristics, such as the medium used to transport the data, communications protocol used, scale, topology, benefit, and organizational scope.

3.Configuration - The makeup of a system. To "configure" is to choose options in order to create a custom system. "Configurability" is a system's ability to be changed or cutomized.

4.Connector - Any plug and socket that links two devices together. Although taken for granted and rarely in the limelight, connectors are a huge industry, and the quality of these components is more critical than most people would imagine. When not designed or constructed properly, they often become the weakest element in an electronic system.

5. Display Adapter - A plug-in card in desktop computer that converts the images created in the computer to the electronic signals required by the monitor. It determines the maximum resolution, refresh rate and number of colors that can be displayed, which the monitor must also be able to support. On many PC motherboards, the display adapter  circuits are built into chipset, ad an AGP or PCI card is not required.

6.Expansion Board - A printed circuit board that plugs into an expansion slot and extends the computer's capability to control a peripheral device. All the boards (cards) that plug into a computer's bus are expansion boards. such as display adapters and sound cards.

7.Expansion Bus - An input/output bus typically comprised of a series of slots on the motherboard. Expansion boards (cards) are plugged into the bus. ISA and PCI are the common expansion buses in a PC.

8.Graphical User Interface - A graphics-based user interface that incorporates movable windows, icons and a mouse. The ability to resize application windows and change style and size of fonts are the significant

advantages of a GUI vs. a character-based interface. GUIs have become the standard way users interact with a computer, and the major GUIs are the Windows and Mac interfaces along with Motif for Unix and the

GNOME and KDE interfaces for Linux.

9. LAN - A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media. The defining

characteristics of LANs, in contrast to wide area networks (WANs), include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines.

10. Motherboard - Also called the "system board," it is the main printed circuit board in an electronic device, which contains sockets that accept additional boards. In a desktop computer, the motherboard contains the CPU, chipset, PCI bus slots, AGP slot, memory sockets and controll ercircuits for the keyboard, mouse, disks and printer. It may also have built-in controllers for modem, sound, display and network, obviating the

need to plug in a card.

11. Network- See computer network

12. Operating System - The master control program that runs the computer. The first program loaded when the computer is turned on, its main part, the "kernel," resides in memory at all times. The operating

system sets the standards for all application programs that run in the computer. The applications "talk to" the operating system for all user interfaces and file management operations.

13. Peripheral -Any hardware device connected to a computer, such as a monitor, keyboard, printer, disk, tape, graphics tablet, scanner, joy stick, paddle or mouse

14. Server - A computer system in a network that is shared by multiple users. Servers come in all sizes from x86-based PCs to IBM mainframes. A server may have a keyboard, monitor and mouse directly attached, or one keyboard, monitor and mouse may connect to any number of servers via a KVM switch. Servers may be also be accessed only through a network connection as well.

15.Sound Card - Also called a "sound board" or "audio adapter," it is a computer expansion board that records and plays back sound, providing inputs from a microphone or other sound source and outputs to speakers or an external amplifier. The de facto standard for sound card compatibility in PCs is Creative Labs' Sound Blaster.

16. User Interface - All graphics based today, the user interface includes the windows, menus and method of interaction between you and the computer. Prior to the Mac, Windows and Motif (UNIX) interfaces, all

interaction was based on commands entered by the user. Operating systems may support optional interfaces and allow a new shell or skin, to be used instead.

17. Virus - Software used to infect a computer. After the virus code is written, it is buried within an existing program. Once that program is executed, the virus code is activated and attaches copies of itself to

other programs in the system. Infected programs copy the virus to other programs.

18. WAN - a Wide Area Network (WAN) is a network that covers a broad area (i.e., any telecommunications network that links across metropolitan, regional, or national boundaries) using private or public network transports. Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical locations. In essence, this mode of

telecommunication allows a business to effectively carry out its daily function regardless of location

19. WEEE Directives - the prevention of waste electrical and electronic equipment (WEEE), and in addition, the reuse, recycling and other forms of recovery of such wastes so as to reduce the disposal of waste. It also seeks to improve the environmental performance of all operators involved in the life cycle of electrical and electronic equipment, e.g. producers, distributors and consumers and in particular those operators directly involved in the treatment of waste electrical and electronic equipment.

INFORMATION SHEET 3.1-2  Computer servers and functions 

Learning Objective:

 After reading this INFORMATION SHEET, YOU MUST be able to identify Computer servers and their functions 

What is a Server? 

Server is a computer program that provides a service to another computer programs and their users. A physical computer which runs a server program is frequently refer to as a SERVER. Servers perform various essential tasks and activities that is a very crucial thing of any organization's IT infrastructure. The many complex processes that take place during an activity, for example a security and authentication to billing and orders, the purchase could not take place without several powerful servers handling the load hence servers are very much important for any organization. 

Functions of Server: 

The main and important function of a server is to listen in on a port for in coming network requests, and a good demonstration of this is the interaction between a Web server and browser. For a user the process is instantaneous, but when he clicks a link while surfing on the Web, several things are taking place behind the scenes like the request for the Webpage is transmitted to the corresponding web server, and the server fetches and assembles the Web page and retransmits it using a protocol like HTTP, and, the user's browser receives the data, converts it, and displays the page. 

The function of a computer server is to store, retrieve and send or "serve" files and data to other computers on its network. Many businesses of all sizes use a local network or "intranet" in their office facilities. On a larger scale, the world-wide computer network we know as the "Internet" depends upon a large number of servers located around the world. The files, data, and functionality of a given website are based on web servers. 

Types of Servers 

There are mainly three types of Server Hardware are as given below :

There are some common servers used by organizations are mention below.

1. Proxy server

It is a server that is called a computer, acts as an intermediary between the user's computer and the Internet and allows client computers to make indirect network connections to other network services.

2. Mail server

A mail server is a computer system that sends and receives email using standard email services protocols like the SMTP protocol that sends messages and handles outgoing mail requests.

3. DNS name

It is a program that uses HTTP to serve the files that form Web pages to users, in response to their requests. Dedicated computers and appliances are may be called as Web servers.

4. Application server

This type of server is acts as a set of components accessible to the software developer through a standard API defined for the platform itself. These are usually performed in the same running environment as their web server(s), and their main work is to support the construction of dynamic pages.

5. Active Directory Server

Active Directory (AD) is consists of several services that run on Windows Server to manage permissions and access to networked resources. AD stores data as objects and it is a single element, such as a user, group, application or device, such as a printer. These objects are normally defined as either resource like printers or computers or security principals such as users or groups.

6. DHCP SERVER

Here DHCP stands for a dynamic host configuration protocol. Which is a network protocol used on IP networks where it is automatically assigns an IP address and other information to each host on the network hence it can communicate efficiently with other endpoints.

7. DNS SERVER

DNS stands for Domain Name System. It is the Internet's system for converting alphabetic names into numeric IP addresses for example, when a URL is typed into a browser, DNS servers return the IP address of the Web server associated with that name.

8. Terminal Server

A terminal server is a network device that enables connections to multiple client server network systems and connect to a LAN network. Microsoft introduced this concept by releasing terminal services as a part of the Windows Server OS.

9. Print Server

It is also called as printer server, which is a device that connects printers to client computers over a network. Print server accepts print jobs from the computers and sends the jobs to the appropriate printers.

10. Real-time communication server

It is a term used for any live telecommunications that occur without transmission delays and it is nearly instant with minimal latency. RTC (Real-time communication server) data and messages are not stored between transmission and reception.

11. FTP server

It is a network protocol used to move computer files between a client and server. FTP (File Transfer Protocol) is built on a client-server model architecture using separate control and data connections between the client and the server.

12. List Server

It is a Server or a server program that handles subscription requests for a mailing list and distributes new messages and other postings from the list's members to the entire list of subscribers.

13. Telnet Server

It is a network text-only protocol that offers bidirectional interactive communications facility using virtual terminal connection. Telnet allows connecting to a remote computer over Internet and using programs and data as if they were on your local machine.

14. Open Source Server

It is a program whose source code is made available to use or modification as users where open source software is always developed as a public collaboration and made freely available.

How Does A Server Works?

In Networking, Servers are named depending on what they serve. It is referred to a system which is capable of serving contents and many important things. The system may be running windows, Linux or other operating systems. Take an example, web server can be running windows, Linux or any other OS depending on your choice. After choosing the operating system for the web server then you can install the software needed for that system to be web server.

Operating system

Operating system is interpreter between computer hardware and software.

1. Client Computer:

It is a computer in your network, where a network user is performing some network activity. Take an example as downloading a file from a File Server, Browsing Intranet/Internet etc. A network user generally uses a client computer to perform his day to day work.

2. Server Computer:

A client computer generates a connection to a Server computer and accesses the services installed on the Server Computer. It is not meant for a network user to browse in internet or do spreadsheet work. A Server computer is installed with appropriate OS and related Software to serve the network clients with one or more services.

An operating system is the most important set of software programs which are loaded initially into any computer-like device by a bootstrap program. OS controls all the resources in a computer, including networks, data storage, user etc.

Learning Objective:

After reading this INFORMATION SHEET, YOU MUST be able to identify

different types of network services.

In computer networking, a network service is an application running at the network application layer and above, that provides data storage, manipulation, presentation, communication or other capability which is often implemented using a client-server or peer-to-peer architecture based on application layer network protocols.

Each service is usually provided by a server component running on one or more computers (often a dedicated server computer offering multiple services) and accessed via a network by client components running on other devices. However, the client and server components can both be run on the same machine.

Clients and servers will often have a user interface, and sometimes other hardware associated with them.

Examples are the Domain Name System (DNS) which translates domain names to Internet protocol (IP) addresses and the Dynamic Host Configuration Protocol (DHCP) to assign networking configuration information to network hosts. Authentication servers identify and authenticate users, provide user account profiles, and may log usage statistics. E-mail, printing and distributed (network) file system services are common services on local area networks. They require users to have permissions to access the shared resources.

Other network services include:

Directory services                                            e-Mail

File sharing                                                      Instant messaging

Online game                                                    Printing

File server                                                        Voice over IP

INFORMATION SHEET 3.2-1

Network services configuration

Learning Objective:

After reading this INFORMATION SHEET, YOU MUST be able to Configure Network Services.

INSTALL AND CONFIGURE ACTIVE DIRECTORY (DOMAIN CONTROLLER)

Active Directory is essential to any Microsoft network built on the client- server network model–it allows you to have a central sever called a Domain Controller (DC) that does authentication for your entire network. Instead of people logging on to the local machines they authenticate against your DC.

Lets take a look at how to install Microsoft’s Active Directory.

Installation

Open Server Manager and click on roles, this will bring up the Roles Summary on the right hand side where you can click on the Add Roles link.

Install a DNS Server

To install a DNS server

1. Open Server Manager. To open Server Manager, click Start, and then click Server Manager.

2. In the results pane, under Roles Summary, click Add roles.

3. In the Add Roles Wizard, if the Before You Begin page appears, click Next.

4. In the Roles list, click DNS Server, and then click Next.

5. Read the information on the DNS Server page, and then click Next.

6. On the Confirm Installation Options page, verify that the DNS Server role will be installed, and then click Install.

Additional considerations

• We recommend that you configure the computer to use a static IP address. If the DNS server is configured to use DHCP-assigned dynamic addresses, when the DHCP server assigns a new IP address to the DNS server, the DNS clients that are configured to use that DNS server's previous IP address will not  be able to resolve the previous IP address and locate the DNS server.

• After you install a DNS server, you can decide how to administer it and its zones. Although you can use a text editor to make changes to server boot and zone files, this method is not recommended. DNS Manager and the DNS command-line tool, dnscmd, simplify maintenance of these files, and they should be used whenever possible. After you begin using DNS Manager or command-line management of these files, editing them manually is not recommended.

• You can administer DNS zones that are integrated with ADÂ DS only with DNS Manager or the dnscmd command-line tool. You cannot administer these zones with a text editor.

• If you uninstall a DNS server that hosts ADÂ DS-integrated zones, these zones are saved or deleted according to their storage type. For all storage types, the zone data is stored on other domain controllers or DNS servers. The zone data is not deleted unless the DNS server that you uninstall is the last DNS server hosting that zone. If you uninstall a DNS server that hosts standard DNS zones, the zone files remain in the % system root% \system32\ Dns directory, but they are not reloaded if the DNS server is reinstalled. If you create a new zone with the same name as an old zone, the old zone file is replaced with

     the new zone file.

• When they write DNS server boot and zone data to text files, DNS servers use the Berkeley Internet Name Domain (BIND) file format that is recognized by legacy BIND 4 servers, not the more recent BIND  format.

Install and Configure Windows Server 2008 DHCP Server

 Dynamic Host Configuration Protocol (DHCP) is a core infrastructure service on any network that provides IP addressing and DNS server information to PC clients and any other device. DHCP is used so that you do not have to statically assign IP addresses to every device on your network and manage the issues that static IP addressing can create. More and more, DHCP is being expanded to fit into new network services like the Windows Health Service and Network Access Protection (NAP). However, before you can use it for more advanced services, you need to first install it and configure the basics.

Istalling Windows Server 2008 DHCP Server

Installing Windows Server2008 DHCP Sever is now a "role" of windows 2008 - not a windows component as it was in the past.

To do this, you will need a Windows Server 2008 system already installed and configured with a static IP address. You will need to know your network's IP address range the range of IP addresses you will want to hand out to our PC clients. your DNS server IP addresses, and your default gateway,Additionally, you will want to have a plan for all subnets involved, what scopes you will want to define, and what exclusions you will want to create.

To start the DHCP installation process, you can click Add Roles  from the initial Configuration Task window or from Server Manager - Roles - Add Roles.                                                       

On the other hand, you can optionally configure your DCHP server during this part of the installation. in my case, I chose to take this opportunity to configure some basic IP settings and configure my first DHCP Scope.

What the wizard is asking is,''what interface do you want to provide DHCP services on?" I took the default and clicked next.

I opted NOT to use WINS on my network and clicked Next.

Then, I was promoted to configure a DHCP scope fort he new DHCP Server . have opted to configure an IP address range of 192.168.1.50-100 to cover 25+ PC Client on my local network. To do this, i clicked Add to add a new scope. As you see below, I named the scope WBS-Local, configured the starting and ending IP address of 192.168.1.50-192.168.1.100, subnet mask of 255.255.255.0, default gateway of 192.168.1.1, type of subnet [wired]. and activated the scope.

I chose to DHCPv6 stateless mode for this server and clicked Next.

Then, I confirmed my DHCP installation Selection [on the screen below] and clicked install.

After only a few seconds, the DCHP Server was installed and I saw the window,below:

Install the File Services server role

To perform this procedure, you must be a member of the Administrator group on the local computer.

1.On Content-01 , click Start , point to Administrative Tools, and then click Server Manager. 

2. In Roles Summary, click Add Roles. 

3. In the Add Roles Wizard, on the Before you Begin page, click Next.
