    Getting online and searching the web

    In areas of good 4G mobile phone reception download speeds can reach 20Mbps, but the average is a lot less. Setting up a computer to use a mobile phone’s connection may be more difficult and less reliable than plugging it into a broadband modem. Note that some search engine only search for exactly the words you enter in the search box and do not offer “stem” or “wildcard” word searching .

    The OR operator will INCREASE the number of records you find. This means you can use Boolean expressions to combine your search terms in a way that will give you relevant results. If a common word is essential to getting the results you want, you can include it by putting a “+” sign in front of it. (Be sure to include a space before the “+” sign.) The one exception to this is “the”, which is so common it … Read More

    How to search the internet

    Given the enormous amount of information available on the Internet, search engines are an essential technology today for the operation of this network. Some people get very good broadband speeds while others have to make do with much slower connections. You can check the speed you’re getting by searching online for Internet speed test and visiting one of the sites to perform a test on your connection. Many of the search engines will give you results with a relevancy ranking. This means that the search engine has listed the “hits” according to how close it thinks the search matches your enquiry. But a word of warning, the results may not be what you are really seeking.

    • Some Search Engines are better than others, with experience you will find those that bring the best results in your subject area.

    How to Use Your PC Computer or Laptop as a Wireless Router

    Between 1986 and 1987, the network grew from 2,000 hosts to 30,000. People were now using the internet to send messages to each other, read news and swap files. After the creation of ARPANET, more networks of computers began to join the network, and the need arose for an agreed set of rules for handling data. In 1974 two American computer scientists, Bob Kahn and Vint Cerf, proposed a new method that involved sending data packets in a digital envelope or ‘datagram’. The address on the datagram can be read by any computer, but only the final host machine can open the envelope and read the message inside.

    For wireless broadband you need to buy a router – or you might get one from your ISP as part of your service package. Remember, your computer or laptop must also be wireless enabled. Broadband gives you much faster access to the … Read More

    Internet Protocols

    Domain Name Servers are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to numerical IP addresses. These crossgrid.org IP addresses are used to identify and locate the web-servers on the Internet. We are not going to describe the application protocols in detail in this document.

    • This layer sets up the communication between the two hosts and they agree settings such as ‘language’ and size of packets.
    • Furthermore, every host implementation of TCP/IP must be prepared to accept pieces and put them back together.
    • (There can be more than one RCPT command, if there are several recipients.) Finally the data itself is sent.
    • This has led to the “server/client” model of network services.
    • Certainly the ARPAnet is the best-known TCP/IP network.

    So we want to be able to use the largest packet size possible. But we also want to be able to … Read More

    Buy Computer Hardware

    Here’s how five of the top technology trends predicted for 2019 could affect your company’s approach to computer hardware. These differences in efficiency mean that one CPU cannot be directly compared to another purely on the basis of clock speed. For example, an AMD Athlon XP 3000+, which actually runs at 2.167 GHz, may be faster than an Intel Pentium 4 running at 3.06 GHz, depending on the application. The comparison is complicated because different CPUs have different strengths and weaknesses.

    NAS drives allow users to access files from both inside and outside of the office or home, making them ideal for storing documents, music and video collections.
