  The components used to establish a local area network (LAN) have a variety of functions. The common unifying theme among them is that they facilitate communication between two or more computers. LAN components are configurable in a variety of ways, but a LAN always requires the same basic components. Network Cards At the most basic level, a network card is a component that allows the computer to communicate across a network. This component is frequently built into the motherboard of today's computers, but it can also be a separate card for use in a PCI slot, or part of an external unit that connects to the computer via a USB port. Network cards are further categorized according to whether they operate on wired or wireless networks. However, some cards do support both wireless and wired networking. Network Cables Network cables are the physical lines used to carry information between computers in a wired LAN. The cables are labeled by their category and are commonly referred to as

  Companies that face concerns about the electronic information they compile, analyze,and share to drive their business need comprehensive solutions for improving network security. With concerns about network security running at an all-time high, along with the limited number of IT personnel capable of addressing them, an increasing number of companies are realizing how outsourcing to managed service providers (MSPs) can strengthen their security posture, reduce hassles and save money. MSPs looking to cash in on these opportunities face their own challenges of how to provide premium offerings to the broadest markets and verticals without having to balance or customize offerings for each client’s unique service and compliance requirements. They also need a way to differentiate themselves from peers and competitors who are also trying to get a piece of this crowded and lucrative pie. find more :   lm security

  If you own a Western Digital hard drive, you may be familiar with the WD SmartWare software application. On a fundamental level, WD SmartWare acts as a data backup tool, allowing you to make copies of valuable information and restore access to it as needed. In an era where busy professionals may use multiple external drives and require immediate access to a trove of information, software such as WD SmartWare helps ensure that vital data remains safe and secure at all times. In the event that you are looking for a reliable backup tool to use in combination with your WD drive, you can master the inner workings of WD SmartWare relatively easily. What is WD SmartWare? WD SmartWare is designed to provide users with administrative controls over their external drives. Much like other software backup tools, WD SmartWare provides users with the ability to schedule automated backups at periodic intervals which will take place without requiring user input. This can be particularly valuable in s

  The network manager job description and responsibilities can be varied -- depending in part on whether the organization relies on a managed service provider -- but generally, the network manager role includes the following duties: ·           Managing and maintaining the network, as well as network performance monitoring ·           Identifying, installing and maintaining upgrades to the network ·           Troubleshooting and repair ·           Overseeing user access to the network ·           Developing a backup/disaster recovery plan for a network emergency ·           Planning network infrastructure for new applications and services ·           Training network staff to provide support to end users ·           Purchasing and maintaining networking equipment and infrastructure ·           Integrating mobile devices into the organization's networks, either (or both of) organizational and personal devices (BYOD) In a large enterprise, network manager job responsibilities may ext

  Sometimes you end up with a great many Windows domain passwords that need cracking – either because you have compromised the domain controller and exported them yourself, or because the client has asked you to perform a password audit and has supplied the database to you themselves. As you know, LM hashes are insecure, and there is a very good way of cracking these (Ophcrack). However, there will also be passwords that cannot be cracked using the standard tables, or maybe the LM hash is not present in the dump at all. In this case, we’ll need to attack the NTLM hash with another tool – in this case a GPU cracker known as Oclhashcat. In this case we have a large (something like 6,000 entry) pwdump format file, with LM and NTLM hashes. Because the LM hashes have various weaknesses in the cryptography, we can crack a lot of passwords using Ophcrack – but in some cases only NTLM hashes are present. In this case we can use a hybrid approach. find more :  l m hash cracker

  Accounting information systems (AIS) simplify financial reporting for purposes of making well-informed decisions. They include all the components of the accounting process: people, procedures, data, software, devices and security. The software is on a device like a computer, and the security is incorporated in the software. People put together procedures and enter data into the accounting software. Types of AIS by Processing Mode Batch processing systems, online batch systems and online real-time systems are the three types of accounting information systems classified by mode of processing. In batch processing systems, you enter transactions when they occur and periodically process and integrate the transactions into the accounting record by running a batch process either daily or weekly. Online batch systems are the same as batch processing systems, except that you record transactions and process batches using online-based accounting software. When using an online real-time system,

  Many people will probably tell you that you need some form of degree in computer science, but that isn’t necessarily the case. Like most technical jobs there are a few qualifications and certificates you may need. One of the top qualifications you will benefit from is a CCNA, which is a Cisco Certified Network Associate certification. It will test both your theory of computer networking but also your practical knowledge in which you might be asked to do within a junior networking engineering role. As a well-respected certification in the industry not only do you look qualified but companies are aware that these tests are difficult to take. Employers For most employers they like to know the network engineer they are employing has some form of technical knowledge, giving them a level of assurance you will know what to do when you start a new role. Having well-qualified network engineers gives makes the company more reliable to work with for customers and helps to boost profitability. P

  CCM, located in Microsoft Windows' System32 folder, stands for Change and Configuration Management. It's a folder created to store temporary files for client installations as a part of the Systems Management Server (SMS) of Microsoft, which is responsible for deploying system-wide installations and updates. Background SMS was Microsoft's enterprise management software that tracks hardware and software inventories, deploys software applications and updates and manages any software changes in a network environment. By 2007, this has become System Center Configuration Manager, which essentially performs the same tasks as SMS. Process SMS or SCCM centralizes the process of software installation into one management application. When a new software or update needs to be deployed, it creates the CCM folder in all computers until the installation or update finishes. The CCM folder contains the Advance Client Installer (ccmsetup.exe), which is responsible for initiating the instal

    Nowadays, practically every personal computer is connected in one form or another to a network. There exists of course the biggest network of all —the Internet— but several other types of smaller networks like LANs (local area networks) and enterprise networks also exist. Network operating systems (NOS) serve as gatekeepers to data and applications on all manner of these networks. Network operating systems don't differ too much from the single-processor operating systems almost every computer user is familiar with, says Andrew Tannenbaum in his book "A History of Operating Systems", but they have their own unique, fascinating history. Birth of Networks The concept of data communications between computers began in the late 1960s and early 1970s, when researchers began developing a way of connecting computers and exchanging information by way of packets of data. Soon, the concept of a local area network (LAN) took hold, replacing the previous model of a central computin

  Bunker Hill security camera systems come with four cameras, cables, power supplies and a digital video recorder, or DVR. Because they come with simple plug-and-play cables, you won't have to worry about installing complicated BNC connectors that come with other camera systems. The cables that come with Bunker Hill security cameras are relatively short -- usually 50 to 60 feet -- so you will want to measure the distance from the camera to the DVR and purchase additional cables if needed. Step 1 Choose the location for your DVR. If you will be routing the cables through the wall, keep in mind exterior walls are difficult to route cables through because most such walls have fire breaks installed inside them about midway up the wall. Cables cannot easily be run through fire breaks so it is better to select an interior wall for the location of the DVR. Also, you should choose a wall that gives you access through the attic or access through the basement. Step 2 Choose the location for

  When it comes to cloud services and software-as-a-service (SaaS), we're all familiar with the usual cloud providers. But for small businesses and larger enterprises, there's a huge world of opportunity and available resources beyond those best-known cloud storage and cloud computing services: Google, Dropbox, Salesforce, Amazon and Microsoft. In this guide to services for business, we're looking at 24 incredibly valuable services that solve real-world business problems. A few of you may have heard about before. Many may be new to you. All are capable of providing nearly instant benefit -- without you having to make any infrastructure investment whatsoever. Often, these bottlenecks aren't because a higher-up didn't actually want the project to go through, but simply never got around to signing off. The approval email might have gotten lost or, if you're still on paper approvals, buried in a huge inbox mound. If you're dealing with accounting and finance app
