Computer Hardware: Desktops and Notebooks and Handhelds

Computers have become ubiquitous in almost every facet of our lives. At work, desk jockeys spend hours in front of their desktops, while delivery people scan bar codes with handhelds and workers in the field stay in touch with the central office via their notebooks. At home, we rely on our desktops and notebooks to do our shopping, to entertain us, and to keep us abreast of world events. We may not see our email servers, but we count on them to deliver our email whenever and wherever we want it. Our PDAs keep track of our hectic schedules, our to-do lists, our contact lists, and even entertain us with games while we're waiting for an appointment or to board a plane. Computer hardware weaves itself through the fabric of our lives.

Even though computer hardware is central to almost everything we do, it's easy to lag behind in the advances made in both hardware and software. Desktops that are four or five years old, for example, become obsolete. You may be able to upgrade operating systems or buy computer add-ons to extend the life of your desktop, but at some point the software, applets, and plug-ins you need to get the most out of your computer simply won't support your old machine.

If it's time to get new computer hardware - whether desktops, notebooks, or PDAs - you'll be amazed at the computing power and the crisp displays that are available, as well as the incredible low prices. Take some time to shop around, and you'll soon discover that online computer hardware sources will save you money over traditional retail stores. When you think about it, it makes sense. According to logic, direct sales cut out the middleman and can pass along the savings to the consumer.

If you're in the market for new desktops, notebooks, or PDAs, there are a myriad of choices. Here's a rundown of some of the best systems available:

Desktops: First, you need to decide - as the advertising campaign so cleverly drives home - if you're a Mac or if you're a PC. If you're a Mac, the iMac Desktop with a 20-inch display can be found for just under $1,500. That includes a 2.16 GHz Intel Core 2 Duo, 1 GB RAM, a 250 GB hard drive, and a SuperDrive.

If you're a PC, the Hewlett-Packard Pavilion S7700N Slimline Desktop PC includes an AMD Athlon Processor 3800 Plus, 1 GB RAM, 250 GB hard drive, SuperMulti DVD Drive, and Vista Premium - the new Microsoft operating system. Price? You can find it for a little over $600.

Notebooks: If you love Macs, you'll adore Apple's PowerBook at just under $2,500. With a 15.2-inch screen at 1280 x 854 resolution and TFT widescreen display, the PowerBook gives you a lot of bang for your buck. It runs on a 1.67 GHz PowerPC G4 and 512 MB RAM, and has an 80 GB hard drive and a SuperDrive.

In the PC universe, the Toshiba Satellite A135-S4427 is a perfect example of the computing power you can get at a very low price. The 15.4-inch widescreen notebook has an Intel Core Duo Processor T2250, 1 GB RAM, a 120 GB hard drive, a SuperMulti DVD drive, and Vista Premium - all for around $900.

When it comes to computer hardware, it pays to shop online. Desktops, handhelds, PDAs, notebooks, servers, and even software can be found at incredibly low prices - so low that you'll want to upgrade all of your computer hardware to the fastest, clearest, best systems available.

Inkjet Cartridges

The question that I lay before you today is, "are inkjet cartridges better or worse than their major competitor the laser cartridge full of so called toner?" There are many facets to this issue, not all of which will be covered in this very short work of art called an article about ink. I do however hope to cover some of the more important points that will help you to decide on what kind of printer you want to purchase namely an inkjet or a laser printer.

Inkjet printers work like a ball point pen in a way. This technology is quite a bit less expensive which makes the printer itself as well as its maintenance cheaper as well. This is probably the largest way in which the inkjet lords it over its competitor the laser. You will save a considerable amount of money purchasing an inkjet and regularly paying for the inkjet cartridges (which are still quite expensive if you ask me) than you will owning and operating the typical laser printer. This is why buy and large the inkjet has held the corner of the personal computing market for a long, long time.

There is some sense in which you pay for what you get in this market of computer printers. With an inkjet printer and inkjet cartridges you have a noticeably lower quality printout. Not really a big deal for the home printer necessities like printing out a map from mapquest quick before a trip but it is enough of a difference that businesses usually find it worthwhile to bite the bullet and purchase the more expensive laser quality printer which will put out superior quality.

Quality can be measured in crispness of print, permanence of ink placement, speed of print, and ability to produce graphics and color. Inkjet cartridges printers are coming into their own however. Their prints are getting faster, more precise, and more smudge free than ever and all while maintaining that low price that everybody loves. Laser is feeling the heat and trying to respond, though moving more slowly, to these "threats."

The one thing that laser printers still have a good hold of is the business market for multi-tasker machines. That is to say that inkjet still has not ventured into the facsimile and/or copier areas and seems to be conceding these areas. Therefore there is room to breath for the lasers over inkjet cartridges printers in this area.

The OSI Reference Model and TCP-IP architecture

The model represents a standard for connecting network systems. The model does not specify the ways in which the individual systems are connected but serves as a description of its layers, functions and services.

The OSI Model consists of seven layers, each of which, as was already stated, receives the services of the layer below and provides services to the layer above.

1. Physical layer
2. Data Link layer
3. Network layer
4. Transport layer
5. Session layer
6. Presentation layer
7. Application layer


Description of the individual layers

Physical Layer

The Physical layer comprises the lowest layer of the OSI model. Its function is to establish, terminate and manage either a point-to-point connection or a point-to-multipoint connection, to effectively distribute the communication resources to the users and to convert the digital data into signals transmitted by the medium.


Data Link Layer

The Data Link layer provides the link between two adjacent network entities, establishes transmission parameters and signals those errors in the physical layer that it cannot correct. The Data Link layer arranges bits into frames and identifies them with MAC addresses. The MAC provides the basis for the local device(s) connection whereby it creates the domain for unicast and broadcast transmission.
Bridges and switches operate at this layer.


Network Layer

The Network layer provides functional means of transferring data from a source to a destination (at variable lengths) via one or more networks while maintaining the quality of service requested by the Transport layer. The Network layer performs routing functions using the services of routers that operate here.

Routers work with a hierarchical addressing scheme. The most widely known protocol of the network layer is the Internet Protocol (IP).


Transport Layer

The Transport layer provides data transfer between end users. The main transport layer protocols are TCP and UDP.

TCP
" a reliable data transfer protocol
" Flow control protocol regulates receiving of data packets and prevents the TCP receiver from overflowing
" Windowing - after certain amount of data packets have been labelled as received (the amount is given by transmission specifications), the sending end user may request transfer of additional data

UDP
" an unreliable data transfer protocol
" used by network applications that do not require the whole of data packets to be received by the receiving host (Internet radios, online games, streaming videos, etc.)


Session layer

The Session layer coordinates data transfer between cooperating session layers.


Presentation layer

This layer is responsible for formatting of the data for application entities. Its functions are code and alphabet encrypting, graphic arrangement modification, etc.


Application Layer

The Application layer provides the application entities with the access to the communication system and thus enables their cooperation.

New Alert System Raises The Bar on School Safety

Parents. School officials. Emergency responders. With thousands of people to notify in the event of an emergency, how would your children's school district handle the situation?

A school district in Klein, Texas, isn't waiting for a crisis to occur to see how it fares. Thanks to funds through grants and private sponsorship, the 39,000 students and 35 schools that make up the Klein Independent School District, one of the nation's largest school systems, is trying out a state-of-the-art alert system during the 2005-06 school year.

Developed by TechRadium Inc., the Immediate Response Information System, also known as IRIS, is a high-speed notification and response service that sends messages to thousands of people in seconds. It was designed after the Sept. 11 terrorist attacks in response to a demand for more efficient ways to notify people in case of emergency.

To operate the system, a designated staff member sends out a message using a phone or Internet-connected computer. IRIS then transmits voice and text alerts to electronic devices, including home and cell phones, e-mail accounts, pagers, PDAs and fax machines. To ensure that the message was received, IRIS confirms completion and redials all missed contacts. Messages can be sent in one of 10 languages.

The system is valuable in sending emergency messages as well as routine school announcements. It requires no hardware, software or system installation for setup, making it a cost-effective way for parents and other community members to stay connected with their local schools.

Wedding Cakes

When planning a wedding reception, be sure to give special attention to the wedding cake. There is, of course, a certain chain of events and best practices that are good to follow.

When you are ready to select a wedding cake, you should arrange to meet with three bakers and taste their products. If you have attended or are planning on attending a bridal show, you can easily and quickly take care of this task at the show.

If you have a certain look you are going for with your wedding cake, be sure to bring a picture of what you would like when meeting with bakers. It is also a good idea to bring along your cake topper if you already have it as well as fabric swatches of the bridesmaid's dresses. Also, be prepared to give the baker an estimated number of guests that you are expecting.

When you meet with the baker, be sure to ask to see a portfolio of pictures that have been taken of the baker's previous work. In addition, always check references before making a final decision.

When you are interviewing the bakers, ask each one the same questions so that you do not forget anything and so that you can make an accurate comparison. Some things to inquire about are the set-up and take-down of the table where the cake will be, who will put the cake topper on the cake, who will place napkins, plates, flowers, etc. on the table, and who will direct the cutting of the cake.

Also, find out where the cake will be stored (it must be out of direct sunlight), who will be in charge of boxing up the cake top and giving to a previously designated person, what arrangements will be made for the left-over cake, and who will cut the cake and distribute it. Cutting a wedding cake is much trickier than it looks and must be done by someone who is familiar with the process.

When you are reviewing a baker's contract, be sure to note several things. For instance, you should immediately see the name, contact person, location, and phone numbers for the bakery. The cake size, shape, and number of tiers must be on the contract. Be sure that the cake flavor(s), fillings, and icing are noted and that returnable items are clearly stated.

Be sure that the number of guests the cake is to serve is on the contract as we;; as when the cake was ordered, when the cake will be delivered and assembled, what the set-up fee is if applicable, and the due dates for deposits and balances. For more information on wedding cakes and other wedding ideas, be sure to go to www.bridalblog.info.

In closing, choosing a cake can really be a lot of fun. You have the chance to sample some goodies and make some light-hearted decisions about fillings, flavors, and decorations. However, in the process, make sure you are noting all of the details that need to be covered so that you are confident in your baker's ability to deliver the product that you are expecting.

Party Jokes: Startling But Unnecessary

Here, I focus on a range of items and features that we use in life without giving them a second thought such as Coca Cola, body muscles and holding ones own breath. Though, most of these notes are not fundamentally necessary, they are such that you can use them for a good laugh, at a drinks party or for picking up women or men.

1) Coca-Cola: Did you know that its original colour was green?

2) Mohammed: Did you know that this is the most used name in the entire world?

3) Geographical Letters: Did you know that the name of each of the continents begins and concludes with the exact same alphabet? Do not believe that? Look up Asia, Europe, Africa, America, Antarctica and the rest.

4) Muscle Strength: Did you know that the strongest muscle in the entire body is that one which we use to lick a popsicle? Your tongue.

5) Credit Cards: In the United States, were you aware that each and every person has at least two credit cards?

6) An Antique Machine: The word for an old machine that was once used for writing letters and other documents is the largest word that one can make if they click only on a single row of their computer's keyboard: typewriter!

7) Blink: Men wink at women, but research has found out that the average woman blinks nearly two times more than the average man.

8) Suicide: Even though you might have wondered if it was possible, studies have discovered that it is impossible to kill oneself by simply holding in your breath.

9) Licking: However much you may try, you will never be able to lick your elbows.

10) Sneeze: Try sneezing. People will automatically answer you with a bless you greeting. Have you ever imagined why? Some say that this happens because a sneeze stops the functioning of the heart for a very tiny second.

11) The Blue Sky: Did you know that a pig, no matter how much they try, cannot look up into the sky?

12) Twisting Your Tongue: We have all dabbled with different tongue-twisters in our day. But do you know which is the toughest? Sixth sick sheiks sixth sheeps sick.

13) Ribs: Did you know that you should try not to sneeze too strongly. Why? A very powerful sneeze has the ability to cause a fracture in your ribcage. But, then again, if you try and withhold one, you stand the chance of breaking one of the many blood vessels in your neck or head. This could cause death.

14) Cards: Did you think that the Kings are all just random cards referring to random figures? No. Each one signifies a different king: Diamonds for Julius Caesar, Clubs for Alexander the Great, Spades for David and Hearts for Charlemagne.

15) And finally: Most everyone reading this (Caught You!) are trying to lick their elbows at this exact moment!
