Cisco Catalyst 3560-48PS EMI - Switch - 48 ports - EN, Fast EN - 10Base-T, 100Ba
The Cisco Catalyst 3560 Series switches is a line of fixed configuration, enterprise-class, IEEE 802.3af and Cisco prestandard Power over Ethernet (PoE) switches in Fast Ethernet configurations that provide availability, security, and quality of service (QoS) to enhance network operations. The Catalyst 3560 is an ideal access layer switch for small enterprise wiring closets or branch office environments that are using their LAN infrastructure for the deployment of new products and applications such as IP telephones, wireless access points, video surveillance, building management systems, and remote video kiosks. Customers can deploy network-wide intelligent services, such as advanced QoS, rate limiting, access control lists, multicast management, and high-performance IP routing - while maintaining the simplicity of traditional LAN switching. Embedded in the Catalyst 3560 is the Cisco Cluster Management Suite (CMS) Software, which allows users to simultaneously configure and troubleshoot multiple Cisco Catalyst desktop switches using a standard Web browser. Cisco CMS Software provides configuration wizards that greatly simplify the implementation of converged networks and intelligent network services. The Catalyst 3560 Series can provide a lower total cost of ownership (TCO) for deployments that incorporate Cisco IP phones and Cisco Aironet wireless LAN access points, as well as any IEEE 802.3af-compliant end device. Power over Ethernet removes the need for wall power to each PoE-enabled device and eliminates the cost for additional electrical cabling that would otherwise be necessary in IP phone and wireless LAN deployments. Maximum power availability for a converged voice and data network is attainable when a Catalyst 3560 Switch is combined with the Cisco Redundant Power System 675 (RPS 675) for seamless protection against internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power outages.

Computer Security Authentication
Computer security authentication means verifying the identity of a user logging onto a network. Passwords, digital certificates, smart cards and biometrics can be used to prove the identity of the user to the network. Computer security authentication includes verifying message integrity, e-mail authentication and MAC (Message Authentication Code), checking the integrity of a transmitted message. There are human authentication, challenge-response authentication, password, digital signature, IP spoofing and biometrics.
Human authentication is the verification that a person initiated the transaction, not the computer. Challenge-response authentication is an authentication method used to prove the identity of a user logging onto the network. When a user logs on, the network access server (NAS), wireless access point or authentication server creates a challenge, typically a random number sent to the client machine. The client software uses its password to encrypt the challenge through an encryption algorithm or a one-way hash function and sends the result back to the network. This is the response.
Two- factor authentication requires two independent ways to establish identity and privileges. The method of using more than one factor of authentication is also called strong authentication. This contrasts with traditional password authentication, requiring only one factor in order to gain access to a system. Password is a secret word or code used to serve as a security measure against unauthorized access to data. It is normally managed by the operating system or DBMS. However, a computer can only verify the legality of the password, not the legality of the user.
The two major applications of digital signatures are for setting up a secure connection to a website and verifying the integrity of files transmitted. IP spoofing refers to inserting the IP address of an authorized user into the transmission of an unauthorized user in order to gain illegal access to a computer system.
Biometrics is a more secure form of authentication than typing passwords or even using smart cards that can be stolen. However, some ways have relatively high failure rates. For example, fingerprints can be captured from a water glass and fool scanners.

Computer Repair Franchises: Buying an Existing Business
Existing computer repair franchises are typically available immediately and are a good option for professionals looking to start a new business in the computer industry. Before deciding to buy a completely new franchise or an existing computer repair franchise, as a prospective business owner you must learn about all the issues involved in buying existing franchises so you don't risk being surprised by the unexpected down the line.
Advantages of Existing Computer Repair Franchises
Computer repair franchises already in existence already have an established performance history. Because of this, you don't have to spend precious time evaluating business potential and can focus on looking at actual earnings. The franchises you want to buy will have a good reputation in their communities and already have loyal clients.
When you buy existing computer repair franchises, you also don't have to worry about finding a location, negotiating a lease or stocking your store with equipment. Similarly, there is no need to hire new employees because the business already has a well-trained staff. With many elements already in place, buying an existing franchise will help you start business much more quickly.
Disadvantages of Existing Computer Repair Franchises
You should investigate an existing franchise before you buy it. Why is the franchisee leaving? If it is for reasons other than retirement, a career change or other issues of that nature, the franchise might not be worth the investment. Perhaps the location isn't making money anymore. Regardless, thorough investigation is necessary.
As a prospective owner, you need to look through all renewals. Sometimes your purchase will only be good for the remaining time on the agreement while other franchises offer new renewals. Also look at lease renewals to make sure they will be renegotiable when your time is up.
Considering advantages and disadvantages of purchasing existing computer repair franchises will help you make the right decision about whether to buy them. They can be good investments if they are profitable and have a good reputation.

Online Computer Degrees, The Key To Success?
Computers are a vital business resource in today?s market. Where several years ago they were a helpful tool, now they are a necessity. Computers have taken an integral part in both personal and professional life. Because of this, many new computer jobs have opened up. From programming to maintenance, computer technology is here to stay. Many people who started working with computers did so in their own time and obtained a vast knowledge by independent learning. This experience can be used to earn a more formal degree and increase earning potential by obtaining an online computer degree.
Computer science, technology, information systems and programming are a few of the computer degrees available online. Online computer degrees offer the flexibility of learning from home. This can be especially beneficial to people who are already working or have family responsibilities. Time constraints can hamper these people from attending traditional classes with rigid schedules, residency and attendance requirements. An online computer degree can solve this problem by allowing people to learn at their own pace, at their own time.
Stay at home parents are ideal candidates for online computer degrees. While the children are at school, the parent can study and take courses online at their computer. They are not missing any responsibilities they have with their children and are using the free time they have to further their education. After a degree is obtained, the parent has more potential for getting employment outside the home. People with degrees generally earn more money even in an entry level position. This can allow the parent to be able to afford day care and have a second income.
Even if a parent chooses to remain home after getting an online computer degree, there are many work-from-home opportunities that are available. One can easily do freelance work in programming or systems administration with a computer degree. These jobs are high paying and have flexible hours. However, without a formal education these types of positions are hard to come by.
Most colleges and universities offer some type of online computer degree program. If there are no local colleges, a quick search on the Internet will result in many options. The majority of the work and learning is accomplished online. Occasionally, you may need to take a test at an authorized testing center. Most of these can be schedules at convenient times and work with local facilities for convenience. Generally, there is no long distance travel nor large blocks of time required.
Obtaining an online computer degree is also usually less expensive than traditional college courses. Because there is no need for a dedicated teacher and classroom facilities, the cost for teaching a student online is much less. Therefore, most online degree programs are less expensive. Many programs also allow you to pay per class as you take classes. Traditional methods have you pay for the entire semester regardless of the number of classes taken. Online classes can help you budget better for an affordable, valuable education.
Obtaining a higher education is becoming more important as people compete for jobs. Having a solid education will give you many more job options and grant a higher earning potential. An online computer degree will allow the flexibility to learn at your own pace while obtaining an education that will have a great deal of value. Since computers are here to stay and we will only see advances in this technology, earning an online computer degree is a great way to advance your education.
