5 Reasons to Choose a Notebook Over a Computer Desktop

5 Reasons to Choose a Notebook Over a Computer Desktop

Many of us are so used to working on a computer desktop that when it comes time to purchase a new computer, we don’t consider other options. Today, computer notebooks – which were once called laptops – offer a number of advantages over a computer desktop. Here are just five reasons why you should take a second look at notebooks.

1. Mobility

You might be used to pulling up a chair to your computer, but it makes much more sense to pull your computer up to your chair. Laptops can certainly be used at your desk, but you also have the option of bringing them to the spot where you’re most comfortable. Maybe you’d like to surf the Web in the evening out in the living room or catch up on your favorite blogs before bedtime. Notebooks with wireless connectivity can travel with you throughout your home, so you can check your email or do your Internet shopping anywhere.

Of course, notebooks also make sense for those who are on the go. Students can take laptops to class and to the library, while businesspeople can take them along while traveling. With WiFi so widely available, it even makes sense to have a notebook while on vacation. With the right notebook, it’s easy to take photos with your digital camera, upload them, and email them to friends and family before you even get back home. Or you can use it to write a vacation blog and include those pictures from your digital camera.

2. Better Displays

The size and quality of computer notebook displays has improved so dramatically that there’s little difference between laptops and a computer desktop. For example, you can get Apple’s MacBook with a 13.3-inch LCD widescreen (1280 x 800 pixels), a 15.4-inch LCD widescreen (1440 x 900 pixels) or a 17-inch widescreen (1680 x 1050 pixels). Similarly, the Compaq Presario has a 15.4-inch display.

3. Lighter Weight

Just a few years ago, even the lightest notebook was a pain to lug around. Today, though, laptops are increasingly easy on the back. The MacBook is slightly over an inch thick and the Toshiba Portege weighs in at about four pounds. While that’s still heavy compared to come of the new ultralight convertibles (Fujitsu’s LifeBook U810 weighs only a pound and half), it’s a significant improvement over the old seven-pound laptops.

4. Better Computing and Battery Power

Historically, two drawbacks of notebooks were their limited RAM, limited space on the hard drive, and short battery life. Times have changed, though, and laptops now have as much power under the hood as their computer desktop cousins. The MacBook, for example, has 1GB of memory (configurable up to 4 GB) and a hard drive that’s configurable to 250GB. This means that your software will hum right along and you’ll be able to zip through programs as quickly and as easily as you do on your desktop. Likewise, batteries in today’s notebooks don’t heat up and don’t conk out.

5. More Features

In older laptops, the computer’s size and weight limited the number and types of features available. Today, with smaller processors and other components, there’s room to pack more features into notebooks. For example, the MacBook has a DVD player, built-in webcam, built-in wireless capability, two USB ports and a FireWire port, built-in microphone, and audio and digital input/output.

There are so many advantages to owning notebooks that, before you buy your next computer, it’s worth your while to take one for a spin.

All About Software Engineering And Development

All About Software Engineering And Development

Software engineering, known as SE, is the development, design, maintenance and documentation of software by applying practices and various technologies from fields such as computer science, engineering, application domains, project management, digital asset management and interface design.

The conception, development and verification of a software system is what software engineering is all about. It is necessary to identify, define, realize and verify the resultant software’s required characteristics. Necessary testing is required for attributes such as reliability, functionality, testability, maintainability, ease of use, availability and portability. In software engineering, software can be verified to meet these requirements by having design and technical specifications prepared and implemented correctly. The characteristics of the software development process are also important in software engineering. Development itself, development duration and risks in software development are examples of such characteristics.

A computer uses software as part of its system that allows the hardware to operate properly. Software can be system software or application software. System software includes the main operating system and a variety of other utilities that enable the computer and its applications to run. Application software includes the computer programs and relevant documentation responsible for end-user data processing tasks. This kind of software is developed for such tasks as word processing, payroll, inventory and production control.

Software Development

A series of processes undertaken systematically to improve a business through using computerized information systems is what is known as software development. There are two major components to software development, which are systems analysis and design.

Systems analysis is the specification of what exactly the system is required to do, or the main objective. Design is about how to make the system do what is required of it. For system analysis, it is required to study the current system by certain procedures in order to gather and interpret data and facts, identify any problems and use this data to improve the system currently in use. System design refers to the process of developing a new system, concentrating heavily on the technical specifications and other specifications that make the system operations.

Software Development Life Cycle

Software Development Life Cycle, or SDLC, is a sequence of events done by designers, analysts and users to develop and execute an information system. There are a number of stages to this practice, which can overlap. The stages are Preliminary investigation (which is feasibility study), Determination of system requirements (which is analysis), Design of system, Development of software, System testing, System Implementation and System Maintenance in that order.

Ergonomics At Work Osha Is On The Job

Ergonomics At Work Osha Is On The Job

The French poet Charles Baudelaire observed back in the 1800s, “Inspiration comes of working every day.” Most people do work every day, and unfortunately it’s not only inspiration that comes of it. Repetitive stress injuries (RSI) are also the result of every day tasks performed again and again while operating a computer. Relief is in sight, however, thanks in part to a particular government agency. This organization is raising awareness and promoting solutions 24/7.

The Occupational Safety and Health Administration (OSHA) has a mandate to protect employees from being hurt in the workplace. James Hodgson, Secretary of Labor, established OSHA within his department in 1971. This was in response to the Occupational Safety and Health Act, legislation he helped author. For the first time in U.S. history, the government stepped in to make sure that workers were as protected as possible from illness, injury, and death on the job. And OSHA had its work cut out for it. Construction, chemical, and agricultural workers were among the many who needed better safety standards in their industries.

But as computer use rose, and the related RSI grew, OSHA turned its attention to this new problem. In recent years, OSHA has developed a four part program designed to reduce injuries and illnesses associated with computer use on the job. The four parts are

Guidelines, Outreach and Assistance, Enforcement, and the National Advisory Committee.

Guidelines are recommended practices that are developed for specific tasks and industries. These are voluntary, not mandatory. Employers use the guidelines to identify and modify risks in the workplace. Implementing these practices reduces injuries related to the way people do their jobs.

The Outreach and Assistance component of this program is aimed at businesses of all sizes. OSHA wants companies to take a proactive stance when it comes to preventing RSI. To help employers, OSHA designed an extensive array of tools that educate, analyze, and train people regarding the ergonomics of their jobs. Available to the public for free on the OSHA website, the computer workstation portion of the Ergonomics eTools is a comprehensive guide to proper computing techniques.

Included in this section is:

Good Working Position (talks about every part of the body and what the best placement is for preventing RSI)

Workstation Components (all the technology and furniture you commonly use is listed here with possible hazards, solutions, and tips)

Checklist (a great way to evaluate how you’re doing ergonomically while you operate a computer)
Work Process (focuses on the physical movements of computer use, with hazards to watch for, more solutions, and tips)

Workstation Environment (information about factors people often don’t think about such as lighting, ventilation, and glare)

But Outreach and Assistance is more than the Ergonomic eTools. It has industry guidelines, cooperative programs, ergonomic analysis info, and success stories. It even has a checklist with tips for new purchases. It is chock full of valuable information for everyone from the individual computer user to the captains of industry.

OSHA persists in its campaign to help employers and employees prevent Repetitive Stress Injuries. If the folks at OSHA have their way, inspiration will be the only result of long hours of work in front of a computer. Baudelaire would approve
