Operating System Networking and Server Management

Operating System Networking

Network software is installed on each computer to enable communication with others.

Services Performed

• File support
• Communications
• Service P / support team

Server Operating System Management

Managing a server in an easy and safe manner is essential for anyone whose professional work involves managing a computer system.

Composition of the Operating System

• Core: This module is the lowest level of an OS. It lies directly on the computer hardware.
• Memory Manager: This module is responsible for absorbing certain portions of main memory for the various programs or program parts that need it.
• System Input / Output: This component presents the user with the I/O data from the device as a separate issue.
• Admin Archives: Responsible for maintaining the data structure, system programs, and different users, while ensuring efficient use of mass storage media.

What is Directory Information?

A grouping of data files, organized by content, purpose, or any criteria decided by the user.

File System

The structure of information stored in a storage unit of a computer, which will then be represented either textually or graphically using a file manager. It is responsible for organizing these sectors into files and directories.

Client / Server Architecture

• Customer: These are the applications and languages used by the user.
• Hosts: The main part of the DBMS that manages the database; these are the machines.

Details of the Archives

• Security or labored
• Mechanisms to avoid fragmentation
• Ability of symbolic links
• File system integrity
• Support for sparse files

Manager User Accounts

These are the unique credentials of a user in one domain, offering the ability to log into the domain to access network resources or to start a local version on a computer to access local resources.

Global and Local Groups

A group is a set of user accounts. The assignment of a user account to a group gives it all the rights and permissions granted to the group. Groups simplify administration by providing an easy way to grant rights common to multiple users simultaneously.

Account Management

• Create templates for adding new user accounts
• Make changes simultaneously on multiple accounts
• Design and implement an account plan
• Troubleshooting

TCP / IP Protocol Suite

The TCP/IP model is a set of protocols designed with a layered architecture like OSI. Its main features include the need for a system to locate a specific computer within the Internet to make the interconnection of computers possible.

The OSI Model

• ISO: International Organization for Standardization
• OSI: Open Systems Interconnection

TCP / IP Layers

• Layers of network access
• The transport layer
• The application layer

Importance of a Layered Model

Ensures efficient data transfer.
