Other than IP what is another example of a protocol that works at the Internet layer of TCP IP?
smtp, http, anything on that specific OSI layer.
Why Can't the IP address 169.254.226.4 be routed on the internet?
Addresses that start with 169.254 are assigned when the computer doesn't find a DHCP server. Probably they are not routed because the network won't be unique - you might have different networks with the same address range. Different subnets have to have different address ranges.

What experience is required for computer science?
Rapidly changing technology requires an increasing level of skill and education on the part of employees. Companies look for professionals with an ever-broader background and range of skills, including not only technical knowledge, but also communication and other interpersonal skills. While there is no universally accepted way to prepare for a job as a network systems analyst, computer scientist, or database administrator, most employers place a premium on some formal college education. A bachelor's degree is a prerequisite for many jobs; however, some jobs may require only a 2-year degree. Relevant work experience also is very important. For more technically complex jobs, persons with graduate degrees are preferred.
For database administrator positions, many employers seek applicants who have a bachelor's degree in computer science, information science, or management information systems (MIS). MIS programs usually are part of the business school or college and differ considerably from computer science rograms, emphasizing business and management-oriented coursework and business computing courses. Employers increasingly seek individuals with a master's degree in business administration (MBA), with a concentration in information systems, as more firms move their business to the Internet. For some network systems and data communication analysts, such as webmasters, an associate degree or certificate is sufficient, although more advanced positions might require a computer-related bachelor's degree. For computer and information scientists, a doctoral degree generally is required because of the highly technical nature of their work.
Despite employers' preference for those with technical degrees, persons with degrees in a variety of majors find employment in these occupations. The level of education and the type of training that employers require depend on their needs. One factor affecting these needs is changes in technology. Employers often scramble to find workers capable of implementing new technologies. Workers with formal education or experience in information security, for example, are in demand because of the growing need for their skills and services. Employers also look for workers skilled in wireless technologies as wireless networks and applications have spread into many firms and organizations.
Most community colleges and many independent technical institutes and proprietary schools offer an associate's degree in computer science or a related information technology field. Many of these programs may be geared more toward meeting the needs of local businesses and are more occupation specific than are 4-year degree programs. Some jobs may be better suited to the level of training that such programs offer. Employers usually look for people who have broad knowledge and experience related to computer systems and technologies, strong problem-solving and analytical skills, and good interpersonal skills. Courses in computer science or systems design offer good preparation for a job in these computer occupations. For jobs in a business environment, employers usually want systems analysts to have business management or closely related skills, while a background in the physical sciences, applied mathematics, or engineering is preferred for work in scientifically oriented organizations. Art or graphic design skills may be desirable for webmasters or Web developers.
Jobseekers can enhance their employment opportunities by participating in internship or co-op programs offered through their schools. Because many people develop advanced computer skills in a noncomputer occupation and then transfer those skills to a computer occupation, a background in the industry in which the person's job is located, such as financial services, banking, or accounting, can be important. Others have taken computer science courses to supplement their study in fields such as accounting, inventory control, or other business areas.
Computer scientists and database administrators must be able to think logically and have good communication skills. Because they often deal with a number of tasks simultaneously, the ability to concentrate and pay close attention to detail is important. Although these computer specialists sometimes work independently, they frequently work in teams on large projects. They must be able to communicate effectively with computer personnel, such as programmers and managers, as well as with users or other staff who may have no technical computer background.
Computer scientists employed in private industry may advance into managerial or project leadership positions. Those employed in academic institutions can become heads of research departments or published authorities in their field. Database administrators may advance into managerial positions, such as chief technology officer, on the basis of their experience managing data and enforcing security. Computer specialists with work experience and considerable expertise in a particular subject or a certain application may find lucrative opportunities as independent consultants or may choose to start their own computer consulting firms.
Technological advances come so rapidly in the computer field that continuous study is necessary to keep one's skills up to date. Employers, hardware and software vendors, colleges and universities, and private training institutions offer continuing education. Additional training may come from professional development seminars offered by professional computing societies.
Certification is a way to demonstrate a level of competence in a particular field. Some product vendors or software firms offer certification and require professionals who work with their products to be certified. Many employers regard these certifications as the industry standard. For example, one method of acquiring enough knowledge to get a job as a database administrator is to become certified in a specific type of database management. Voluntary certification also is available through various organizations associated with computer specialists. Professional certification may afford a jobseeker a competitive advantage.

What are the ways of reducing load on routers?
Basically, the more antennas you have the faster your network can perform. Say you have 10 computers on your network with one router that only has one antenna. That one antenna is sending and receiving the requests for ten computers. when you incorporate additional routers, there are more antennas to manage the load from the ten computers. Also, if you set up a second wireless router as an access point in a different location than your primary router, you can double your wireless range.
Has the internet changed the way people live?
Easily! The world has become much smaller since the creation of internet. You can research just about anything without ever leaving home; vacations, hotels, medicine, any subject in school. You can find answers to questions you are clueless about...on sites like Wiki. You can visit art gallaries, map locations, map sites with cameras to check everything from jail cell behavior to squirrel behavior; views on freeways, to views of constellations. There are times you can log in and talk to astronauts WHILE they are in space. As for students, you now do joint projects with other kids all around the world in REAL time...you talk to each other, as it happens and can watch each other's expressions. You can write letters...without stamps, make calls...without phones, text message to phones, watch TV, and download songs all without ever leaving your chair. There are businesses now that are totally run from home and still connect to people around the world and where else could people in 10 countries all bid on some bizarre thing on auctions and work in the last minute to outbid each other. Let's not forget banking, applying for college, loans, buying cars, checking out library books...just download them onto your IPOD to save time, and do all this while you have pictures being sent out to print, answering mail, and watching a movie in different windows. Yep, just a little change.
How long does it take to upload a video on YouTube?
It depends on the file size. A 2 minute video could take 2 mins, 2 hours, 18 hours, or 5 days. Depends on your size of the file. I'm uploading 10-20 min. videos on youtube, and they range from 80 mb-180 mb in size and they always take from 30 mins to an hour to upload.

How does internet surfing help the students?
It depends how you actually use the internet and what resources you have access too. As a film and media lecturer I would definitely try and steer my students away from non academic websites such as imdb or wikipedia, simply because the issue of referrencing and of valid information sources may fall into question. However I would encourage them to use the likes of Jstor or other such academic online journals providing they have access. I would also recommend the likes of sensesofcinema.com or kinoeye.org as these sites have good, well referrenced academic credentials. But of course it all comes down to the subject one is studying. Just make sure that if you are using the internet the page you are using has good academic credentials, perhaps consult your lecturer/professor on what sites they recommend/suggest.
Are you legally permitted to copy the webpage and add it to your website?
The quick'n dirty answer is no.
However, some sites will put their copyright rules in the policy pages and may allow you to copy some of their content, as long as you leave a 'source' link back to their site.
To be safe, I would check their terms or avoid the copy/paste practice if you can.
