WHAT IS E-MAIL

Short for electronic mail, the transmission of messages over communication networks.

The messages can be notes entered from the keyboard or electronic files stored on disk.

Most mainframes, minicomputers and computer networks have an e-mail system. Some electronic-mail systems are confined to a single computer system or network, but others have gateways to other computer systems, enabling users to send electronic mail anywhere in the world. Companies that are fully computerized make extensive use of e-mail because it is fast, flexible, and reliable.

Most e-mail systems include a rudimentary text editor for composing messages, but many allow you to edit your messages using any editor you want. You then send the message to the recipient by specifying the recipient's address. You can also send the same message to several users at once. This is called broadcasting.

Sent messages are stored in electronic mailboxes until the recipient fetches them. To see if you have any mail, you may have to check your electronic mailbox periodically, although many systems alert you when mail is received. After reading your mail, you can store it in a text file, forward it to other users, or delete it. Copies of memos can be printed out on a printer if you want a paper copy.

All online services and Internet Service Providers (ISPs) offer e-mail and most also support gateways so that you can exchange mail with users of other systems. Usually, it takes only a few seconds or minutes for mail to arrive at its destination. This is a particularly effective way to communicate with a group because you can broadcast a message or document to everyone in the group at once.

Although different e-mail systems use different formats, there are some emerging standards that are making it possible for users on all systems to exchange messages. In the PC world, an important e-mail standard is MAPI. The CCITT standards organization has developed the X.400 standard, which attempts to provide a universal way of addressing messages. To date, though, the factor addressing standard is the one used by the Internet system because almost all e-mail systems have an Internet gateway. 

LAPTOP

A laptop computer is a personal computer for mobile use.  A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad or pointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. Laptops are also sometimes called notebook computers or notebooks.

Portable computers, originally monochrome CRT-based and developed into the modern laptops, were originally considered to be a small niche market, mostly for specialized field applications such as the military, accountants and sales representatives. As portable computers became smaller, lighter, cheaper, more powerful and as screens became larger and of better quality, laptops became very widely used for all sorts of purposes, by all sorts of people.

HISTORY

As the personal computer became feasible in the early 1970s, the idea of a portable personal computer followed. A "personal, portable information manipulator" was imagined by Alan Kay at Xerox PARC in 1968 and described in his 1972 paper as the "Dynabook".

The IBM SCAMP project (Special Computer APL Machine Portable), was demonstrated in 1973. This prototype was based on the IBM PALM processor (Put All Logic In Microcode).  The IBM 5100, the first commercially available portable computer, appeared in September 1975, and was based on the SCAMP prototype.

As 8-bit CPU machines became widely accepted, the number of portables increased rapidly. The Osborne 1, released in 1981, used the Zilog Z80 and weighed 23.6 pounds (10.7 kg). It had no battery, a 5 in (13 cm) CRT screen, and dual 5.25 in (13.3 cm) single-density floppy drives. In the same year the first laptop-sized portable computer, the Epson HX-20, was announced.  The Epson had a LCDscreen, a rechargeable battery, and a calculator-size printer in a 1.6 kg (3.5 lb) chassis. Both Tandy/RadioShack and HP also produced portable computers of varying designs during this period.

The first laptops using the flip form factor appeared in the early 1980s. The Dulmont Magnum was released in Australia in 1981–82, but was not marketed internationally until 1984–85. The $8,150 ($19,630 today) GRiD Compass 1100, released in 1982, was used at NASAand by the military among others. The Gavilan SC, released in 1983, was the first computer described as a "laptop" by its manufacturer.  From 1983 onward, several new input techniques were developed and included in laptops, including the touchpad (Gavilan SC, 1983), the pointing stick (IBM ThinkPad 700, 1992) and handwriting recognition (Linus Write-Top,  1987). Some CPUs, such as the 1990 Intel i386SL, were designed to use minimum power to increase battery life of portable computers, and were supported by dynamic power management features such as Intel SpeedStep and AMD PowerNow! in some designs.

Displays reached VGA resolution by 1988 (Compaq SLT/286), and colour screens started becoming a common upgrade in 1991 with increases in resolution and screen size occurring frequently until the introduction of 17"-screen laptops in 2003. Hard drives started to be used in portables, encouraged by the introduction of 3.5" drives in the late 1980s, and became common in laptops starting with the introduction of 2.5" and smaller drives around 1990; capacities have typically lagged behind physically larger desktop drives. Optical storage, read-only CD-ROM followed by writeable CD and later read-only or writeable DVD and Blu-Ray, became common in laptops soon in the 2000s.

KEBURUKAN ICT DALAM PENDIDIKAN AWAL KANAK-KANAK

Pada zaman sekarang,  kanak-kanak juga tidak ketinggalan dalam mengikut rentak arus globalisasi ini.  Mereka boleh membuka dan menutup komputer serta boleh menerokai perkara-perkara baru.  Namun sejauh manakah ICT boleh membawa manfaat kepada kanak-kanak khususnya dalam pendidikan awal kanak-kanak kerana ict juga boleh membawa keburukan kepada mereka.


  

Bagi ibubapa sekarang, terutamanya yang bekerja di kota metropolitan lebih cenderung bekerja daripada pagi hingga malam.  Kanak- kanak akan menjadi bosan kerana tiada kawan untuk mereka bermain jadi mereka memilih untuk bermain permainan dalam komputer.  Tugas mengasuh diberikan seratus peratus kepada orang gaji menyebabkan  mereka tidak mendapat kawalan daripada ibubapa mereka sendiri.

Oleh kerana kanak-kanak ada sifat ingin tahu yang tinggi dalam diri mereka maka mereka akan terusan bermain sehingga dapat mengetahui apakah yang berlaku pada penghujung permainan itu.  Mereka boleh menjadi ketagih dalam permainan komputer.

Terdapat beberapa keburukan ICT dalam pendidikan kanak-kanak seperti 

• Perkembangan mereka tidak akan berkembang kerana hanya duduk bermain komputer.
• kanak-kanak dapat mengetahui perkara yang melangkaui batas umur mereka.  
• kanak-kanak akan malas belajar dan cepat menjadi bosan dalam sesi pembelajaran.

Penggunaan ICT kepada kanak-kanak haruslah dengan bimbingan dan guru-guru juga harus kreatif menyampaikan pengajaran mereka tanpa bergantung sepenuhnya kepada ICT.  Mencari maklumat dan teknik terbaru memanglah digalakkan kepada semua guru-guru di tadika namun jika ia disalahgunakan apa ertinya teknologi maklumat yang canggih sekiranya anak-anak didik kita menjadi mundur ke belakang ddan tidak ddapat berfikir ke arah pembentukan masa depan terutamanya tidak dapat memajukan negara. 

ADVANTAGES ONLINE SHOPPING

The internet has made many things possible which were previously

Unimaginable such as online shopping is one of them.  The benefits of

Online shopping and the number of people turning to the internet for shopping

are in plenty and undeniable.  What are those advantages of online shopping..???

Here are a few of them which remain at the top of the list.......

VARIETY

The variety of product is one of the most compelling reasons why online

shoppers go on the internet and choose from an endless range of products. 

Comparatively, brick and mortar retailers cannot offer such a wide range of product

as their online counterparts.  The choice of products in online shopping is not limited to

your area of retailers or shopping stores.  While shopping online, your hardly think

of your favorite merchandise going out of stock as there are always other sellers

offering the same product.

CHEAPEST PRICE

As you browse through thousands of online sellers, you enjoy the freedom of

Buying products that are the cheapest.  Online seller also have the advantage of

Not incurring expenses of physical stores which a conventional store has to bear.

This allows online stores to sell products at a lower rate than physical shopping stores.

That results into online stores selling at much cheaper rates.

TIME SAVING

What we are most concerned about is time.  Time saving is one of the

Greatest benefits of online shopping.  Traditionally, people had to spent

weekends, days and hours shopping for family and on special occasions.

Online shopping brought relief to those time conscious people and gave them

The ability to make purchases from the convenience of their home in their time.

CROWDING

While many people need go to the stores for shopping but online shopping

We do not need crowded in the stored with others people.  These are the

People who seek privacy, higher level of attention from sellers and the comfort

Of not being pushed around in stores.

ENVIRONMENTAL CARE

Every year, millions of barrels of oil are consumed when shoppers travel to stores and malls.

Seller package their product and add many frills to them when selling off their physical

Stores, which leads to an enormous amount of garbage.  Online shopping cuts down

Packaging and decor of product compare to selling products at brick and mortar stores.

EXAMPLE WE CAN GET WHEN USING ONLINE SHOPPING.
