The Advancement Of Pc Laptop Computers

Posted on by blogger

While technology in general has changed over the last 10 years, making life easier and more convenient, PC laptop computers have by far made the most change. In addition to the computer itself evolving, everything about the computer has been enhanced. This means computers today are smaller, faster, and they cost far less than a decade ago.

If you use a computer while on business, at college, or you like to take a computer with you while taking a vacation, the options today are amazing. Most people will choose the standard type of laptop but the notebook is another great option, which again, is much smaller and even lighter in weight. However, the notebook offers better portability than a standard laptop.

Looking at PC laptop computers now being sold, you cannot help but be in awe. For one thing, computers are lighter and while not all have had much change, the amount of power now offered and the incredible speed when on the internet is without doubt astonishing.

Even though people all look for something different, having a computer with a web cam, built-in keyboard and mouse, battery that lasts longer, DVD/CD burning drive, and wireless technology means you get everything needed and more.

Of course, you could stick with a desktop computer, which still works great, but the mobility and built-in features associated with PC laptop computers make them the favorite choice. This means you can take the computer wherever you go and have internet connection, allowing you to email, handle business meetings, or simply play online games.

This means you could connect to the internet while waiting for your next flight, while in your hotel room while traveling on business, or sit out by the pool with a friend and just play games or answer emails. To enjoy internet connectivity but without running down the battery, all you need is a standard electrical outlet.

PC laptop computers have even changed in size. Today, the smaller options are about 10×8 inches that comes with a 13-inch monitor but if you like a more normal size, then you could go with a 15×11-inch computer with a 17-inch monitor. Along with the actual computer being smaller, these laptops are also thinner.

The smaller computers now have a thickness of just 0.7 inches whereas the larger ones are about 1.5 inches, which is still thinner than earlier models.

The Challenge of NFC for the DoD

NFC access card technology, via smart phones, like the Blackberry and iPhone. NFC is near field communication and is essentially two-way RFID, or radio frequency identification. NFC key cards are already in use in the hotel and airline industries, with downloadable room keys and boarding passes. Experts believe that eventually driver’s licenses and passport information will migrate to the NFC platform, but currently, there are too many problems with issuance, interoperability and security, that must be resolved first. One major issue for NFC-enabled mobile devices is that older cell phones do not have the installed chips. Existing smart phones without embedded NFC readers could work via Bluetooth tethering or a USB port.

The DoD put out a request for information in September of 2010, to start looking at NFC, to replace its Common Access Card and government employees’ PIV, or personal identity verification, credentials. Used by three million people for logical and physical access, the DoD CAC/PIV smartcard would be a big boon to the winning developer of the chip technology contract. The DoD is considering adding global payment, ATM access, and management of public transit service benefits to the card’s functionality. The DoD would also like to develop a debit card for military personnel, to be able to buy groceries both on and off base.

NFC is divided into two camps, open and secure. Open NFC allows for checking into hotel rooms, stores, or flights. Secure NFC enables financial transactions, whether through NFC access keys or NFC-enabled smartphones. The former can be developed much more rapidly than the latter because of the necessity of multiple layers of security and the complex nature of creating data protection software. Security is obviously the biggest concern for the DoD. Because of the many platforms and systems that support NFC, the potential for hackers and cyber-terrorists to develop viruses and malware is great.

Another problem, with NFC-enabled smartphones, is access control. PIN numbers and pattern codes for locking the phone are common, but the mechanism is usually optional. Any NFC mobile device approved for military use would need additional security layers. Some solutions to this are one-time passcode generators, biometrics, and GPS location tagging. The cameras on smartphones could be utilized for facial or iris recognition or fingerprint swiping. The phone’s GPS technology could flag fraudulent activity from individuals attempting to gain access from a computer that is far removed from the mobile device.

The rate of innovation for mobile apps is a further vulnerability in security. New versions of software are released at a frenetic pace and present problems for organizations trying to keep up. Imagine deploying and maintaining the technology over an organization the size of the Department of Defense. Whether the DoD goes with NFC-enabled smartphones or NFC access keys, it will certainly be a challenge. “>The U.S. Department of Defense (DoD) is considering replacing its Common Access Card with NFC access card technology, via smart phones, like the Blackberry and iPhone.

Computer Networking

Posted on by blogger

The basic concept of computer networking is having two or more computers connected together sharing information. The information shared can be files, printers, and programs. The size of a computer network largely depends on the user’s needs. If you are building a home network, then you will likely have one to three computers networked. In a large office, you may have as many as 100 or 200 computers networked together.

Types of Networks
There are different ways to perform computer networking. Wireless networks, or WLAN/WWAN, uses wireless technology to network computers together. This type of computer networking is becoming more popular for the home user. Using a router and a host computer, you can connect multiple computers in your house to the network. If one of those is a laptop, it’s possible to take that computer from room to room as you work. Local area networks, or LAN, are smaller networked areas. Local area networks usually have higher data transfer rates, and do not require special telecommunications services. Wide area networks, or WAN, connects a large group of computers together. These networks are typically designed for one organization’s use. Metropolitan area networks, or MAN, are networks that usually span the size of a city. They use fiber optic cables and are usually wireless. ATMs use metropolitan computer networking.

The OSI model, or Open Systems Interconnection Reference Model, is a type of computer networking that uses layered communication. The seven layers are arranged from bottom to top as: physical, data-link, network, transport, session, presentation, and application. The OSI Model was too complicated to be useful in today’s computer world. Even so, it is still often referenced by IT professionals when they are describing computer networking or network applications.

By setting up a computer network at home, or in your office, you can give multiple users access to files on the host computer. It’s also possible to have users able to share files between their computers. Printers and programs can also be shared among users on a computer network.

This is just a small view into the world of computer networking. Setting up a computer network in your home has never been easier. Today’s technology makes it possible with just a few simple steps.

How To Manage A Computer Network

Posted on by blogger

Today it is almost inconceivable for a company that do not have computers or a building or a high-tech company. If a company more than one computer, usually are linked in a LAN. These networks may be more or less sophisticated and cheaper or more expensive. Companies invest a lot (both in terms of time and money) on a local network, as there are many benefits that a local network, a business meeting and how it should be administered.

Some companies use a local network, so they depend heavily on the job forever. If the failure of the corporate network, you can see all the people talking in the hallways because they cannot do their job. This means that large losses for the company and creates risks to workers. All companies should consider their local networks, an important advantage and downtime must be avoided. This places high demands on the network of staff in these networks of approximately 100% of the clock is ticking.

The benefits of network management software
An important advantage of the installation and maintenance of LANs is the opportunity to improve communication and collaboration between employees and customers to create.

Security considerations: security of local area network can be an obstacle for aid and suffer. global security is an advantage, as it provides a central strategy for improving access and the safe handling and disaster. All information will be protected in the design and implementation of network security solution. In addition, networks of computers in the network create a security risk, and that makes it technically possible for someone too many computers on the network once access.

Economic considerations: the installation of a LAN is a relatively expensive project. Servers, cabling, switches, routers and software can be expensive and cannot be purchased without professional advice. Continued use of the secure network, and resource intensive and can be expensive.

Surprisingly, a LAN has a number of cost savings. Share resources avoid the need to buy for each device. Even more important is the security offered by the Internet. Data loss can be costly for society and in some cases, the chief of the cases to a complete stop. Network Equipment Administration should require a consistent routine data backup with regular checks on the quality of data – a practice that company huge sums of money in case of failure will save.

Computer network management: preliminary analysis of phase
The first phase of the computer network management is the source of the problem of identification (a preliminary study various options for different sizes can be considered useful) and the definition of the requirements. Examples of what is necessary to assess other network operating systems, messaging systems and other applications. The choice of hardware should also be considered. This is usually to define what the system should do, not what we should aspire to.

Computer network management: Design

The design objective is to determine how the requirements of the specification requirements. The current approach is too large and complex projects, which is broken into smaller, more manageable subprojects.

Computer network management: The Implementation phase

This phase includes the physical installation of the LAN. The cable is passed, it installs the software and computers and other equipment are created.

Network Computer Management: Integration and System Test

In this phase, the implementation of the network starts and routines adapted to the users and operators. The system should be tested, both to ensure the system meets the requirements of the specification and sufficiently stable for the central role of the organization.

Network Computer Management: Operation and Maintenance

Local networks are complex operating system routines. That is because it can have serious consequences in case of malfunction or unauthorized access of people to the system. Many companies have the care of employees is dedicated exclusively to the implementation and maintenance of computer networks, to drink.

Network Computer Management: Tools
Although the organization cannot be managers must also monitor the network for more than eight hours a day. In fact, some of the worst problems that can occur with nets during the night, when nobody can do in the network. With network management tools of quality, the organization can be sure that problems will be given to prevention and clean – and your network administrator for a moment the notice shall be served as an extraordinary error.
