This module was designed to give you knowledge and demonstrate an

understanding of concepts and principles in setting up computer servers. It gives you a

clear picture on how to able to set up computer servers based on acceptable standards and

hardware.

In order for you to finish this module successfully you have to understand clearly

and follow the directions correctly.

After going through this module, you are expected to:

1. create user folder in accordance with Network operating system features;

2. configure user access level based on NOS features;

3. established network access level

4. perform security check in accordance with established network access policies/end-

user requirements;

Directions: Choose the letter of the best answer. Use a separate sheet of paper for your

answers.

1. Which of the following best describes Network Operating System?

a. It supports file sharing among workstations

b. It manages workstations in the network

c. It provides printer sharing

d. All of the above

2. The following are examples of Network operating systems except____

a. Windows Server c. Mac OS X Server

b. Linux d. Windows 7

3. It is a type of network operating systems that share resources among computer connected to the network without central control is called____________.

a. Peer to peer network c. Mac OS Server

b. Client-server network d. Windows Server

4. It is a type of network operating systems that requires regular updates and maintenance is called ____________.

a. Peer to peer network c. Mac OS Server

b. Client-server network d. Windows Server

5. One of the advantage of peer to peer network is the ease of set-up. How you would describe it?

a. New technology can be integrated into the system

b. Server is necessary to complete the set-up

c. Less hardware is needed

d. All of the above

Before we move on, let’s see if you can still remember your past lessons when you were in

Grade Nine (9).

Arrange the jumbled words to identify what is being described in the sentence. Use a

separate sheet of paper to write your answer.

1. I T N G A R O E P M E S S Y T- the software that supports a computer's basic functions, such as scheduling tasks, executing applications, and controlling peripherals.

2. D O S W N I W E E R V S- is a series of enterprise-class server operating

systems designed to share services with multiple users and provide extensive administrative control of data storage, applications and corporate networks. the ability to handle the business

3. R E M O C U P T W R O N T E K – is a set of computers connected together for the purpose of sharing resources.

4. R E V S R E – a computer or computer program which manages access to a centralized resource or service in a network.

CLIENT WINDOWS SHARE LINUX

SERVER SECURITY RESOURCES

NETWORK CENTRALIZE HARDWARE

A network operating system

(NOS) is an operating system designed for

the sole purpose of supporting

workstations, database sharing, and

application sharing and file and printer

access sharing among multiple

computers in a network.

Examples of Network Operating Systems:

Types of Network Operating Systems

1. Peer-to-peer network (P2P) operating system users are allowed to share resources and files located on their computers and access shared resources from others.

2. Client-server network operating systems allow networks to centralize functions and applications in

one or more dedicated file servers. The server is the center of the system, allowing access to resources and instituting security.

Advantages and Disadvantages

ADVANTAGES

• Centralized servers are more stable.

• Security is provided through the server.

• New technology and hardware can be easily integrated into the system.

• Hardware and the operating system can be specialized, with a focus on performance.

• Servers are able to be accessed remotely from different locations and types of systems.

• Ease of setup

• Less hardware needed, no server need be acquired

DISADVANTAGES

• Buying and running a server raises

costs.

• Dependence on a central location for operation.

• Requires regular maintenance and updates.

• No central location for storage

• Less security than the client–server model

Directions: Complete the table. Compare and contrast Client-server computer from peer to peer network.

Client-server network vs. Peer to peer network
