SYS-ED/COMPUTER EDUCATION TECHNIQUES, INC. (Solaris – System Admin: Intro - 6.5) Ch 2: Page i Solaris System Administration: Introduction 1 Operating System Concepts Operating System: Definition An operating system is the set of programs that controls a computer. The core of the operating system is the kernel. The kernel is a control program that functions in privileged state that allows all hardware instructions to be executed. It reacts to interrupts from external devices and to service requests and traps from processes. The kernel creates and terminates processes and responds to requests for service. Operating systems are resource managers. The main resource is computer hardware in the form of processors, storage, input/output devices, communication devices, and data. Operating system functions include: • Implementing the user interface. • Sharing hardware among users. • Allowing users to share data among themselves. • Preventing users from interfering with one another. • Scheduling resources among users. • Facilitating input/output. • Recovering from errors...

The report is mainly about the types of computer network and their functions. Computer and Networking. A computer is a programmable machine, which is designed to sequentially and arithmetically carry out a sequence of logical operations. The particular sequence of operation allowing to solve more than one kind of problem. It responds to a specific set of instructions in a well defined manner. It can execute a pre-recorded list of instructions. Main components of computers are input, output and process. (Thakur) According to (Mitchell, What is (Wireless...

...NETWORK SECURITY Introduction Network security is a major issue when developing a new computer system. A few of the issues that the new WInt must address are accidental disruptions to the system, loss or theft of sensitive data by employees, malicious attacks to system, and theft of intellectual property by employees (National Institute of Standards and Technology, 2014). The accidental disruption to systems are caused by employees who input mistakes or leave out important data during input; these mistakes and omissions are typically caused by data entry clerks that input a lot data every day or other system users who create and edit system data. WInt would need to implement applications that use quality control protocols, as well as requiring all users with system access to be trained to help reduce this type problems (National Institute of Standards and Technology, 2014). Loss or theft of sensitive data by employees can be described as computer crimes by people who have or get access to the system and steal or destroy sensitive information on the system. The majority of these crimes are committed by disgruntled, current employees, although some are committed by former employees who keep all their system log-in information, who use their access to commit fraud, theft or destruction of system data (National Institute of Standards and Technology, 2014). Malicious attacks to the system are caused by malicious software like viruses, worms, Trojan...

...WIRELESS NETWORKING Introduction A wireless network is any type of computer network that uses wireless data connections for connecting network nodes .Wireless networking is a method by which homes, telecommunications networks and enterprise (business).Installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. Examples of wireless networks include cell phone networks, Wi-Fi local networks and terrestrial microwave networks. Wireless network made up of There are two kinds of wireless networks: * An ad-hoc, or peer-to-peer wireless network * Access point Ad-hoc or peer-to-peer wireless network It consists of a number of computers each equipped with a wireless networking interface card. Each computer can communicate directly with all of the other wireless enabled computers. They can share files and printers this way, but may not be able to access wired LAN resources, unless one of the computers acts as a bridge to the wired LAN using special software. (This is called "bridging") Each computer with a wireless interface can communicate directly with all of the others. Access point or base station A wireless network can also use an access point...

...ITDM IT WATCH ON VIRTUALIZATION SUBMITTED BY GROUP 9 CONTENTS 1. INTRODUCTION TO VIRTUALIZATION 2. TYPES OF VIRTUALIZATION 3. ADVANTAGES OF VIRTUALIZATION 4. VIRTUALIZATION IN INDIA 5. REFERENCES INTRODUCTION Virtualization is the creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources. In layman's term, virtualization allows you to run an independent operating system within an existing operating system using the existing hardware resources. So if you want to learn another operating system like Linux, you can use virtualization to run Linux on top of the existing operating system. Virtualization is the abstraction of IT resources, separating their physical instance and boundaries from their function. Virtualization has brought important innovation to IT Virtualization concept was first developed by IBM in the 1960s to fully utilize mainframe hardware by logically partitioning them into virtual machines. These partitions will allow mainframe computers to perform multiple tasks and applications at the same time.. During the 1980s and 1990s, desktop computing and x86 servers become available and so the virtualization technology was discarded eventually. Client-server applications and the emergence of Windows and Linux made server computing significantly inexpensive...

...INDP, Part 4 NTC/362 INDP, Part 4 Kudler Fine Foods is a small network considering that it spans across only three locations. Currently the network is utilizing a dedicated T3 connection between the stores with the La Jolla facility hosting the central servers. Each facility will have two firewalls, one for the intranet and one for the internet. An HP Blade Server model c3000 will be installed at each facility and will serve as the print/file server, communications, email, storage and web server. In addition to the Blade Server system La Jolla will also have a 10TB NAS to maintain records of all system transactions across the network. Operating on the network will be 31 computers, of these computers 13 will belong to the corporate admin and the remaining 18 will be utilized by the local store management. An APC Smart UPS rated at 5000va will be installed in each of the three server rooms. Telephonic communications will be made available using VOIP. La Jolla will have 19 total VOIP phones in order to accommodate the number of corporate administrators, the Del Mar and Encinitas facilities will only have 6 VOIP phones. The standards being applied to this project are LAN, WAN, Wireless, and VOIP. A LAN or local area network is created when multiple computers or devices are connected as a network providing services and applications within a common structure such as a single business, campus or region. A LAN is generally governed by the organization by an administrator who controls...

...Network Design Student Name Course 2 July 2014 Professor Identify hardware and software needed to secure your choice of networks against all electronic threats. A network that helps a workstation to connect with each other is called a Networking hardware. If a company uses both routers and firewall, the company is assured protection of both wireless and cabled networks that are used in the company. Network hardware is suitable in any organization in the keeping of the organizations network safe. In the software part I will choose to use McAfee Anti-virus security software. This software in conjunction with firewall is a sure way of protecting a company. Routers when used along with hardware are the best security hardware needed if the company needs to increase the security of their network to a level where none of the intruders can be able to access it (Radu, 2002). The function of the firewall in an organization is to ensure that all unwanted activities are blocked including hackers that can retrieve important and delicate information of the company. Hacking will be a very dangerous exercise where criminal can access the important information that a company has and use this information in blackmailing the company and its customers. Networking software’s also plays a major role in securing an organizations network security. The software has the capabilities of detecting viruses that may attack an organization and make an organization loose its critical...
