What Happens at the Office Visit During these early months, your doctor will check your baby's progress and growth. Common parts of a checkup include: weight, length, and head circumference measurements that are plotted on your baby's growth chart a physical exam with special attention to any previous problems assessing development for example, head control, cooing, and smiling questions about how you're doing with your baby advice about feeding and other aspects of nutrition what to expect during the coming months, including a discussion about safety precautions immunizations during some visits Bring up any questions you have, and write down the answers or specific instructions the doctor gives you.
In , the International Electrotechnical Commission defined new prefixes for the byte to be used in addition to their SI International System of Units counterparts, with the intent that the SI prefixes would be used when referencing bytes. The new prefixes would be used when referencing multiples of bytes 2 10 , which is the binary definition of bytes used in information technology. Current use: Bytes are widely used when referencing data storage, particularly storage media such as hard drives, flash-based storage, and DVDs, though these are more often presented in terms of larger multiples of bytes such as megabytes or gigabytes.
The two words are synonymous in this context. So how big is too big? Obviously, it depends on the context. If you are signing off on a report that is intended to go to the printers, then emailing a 10MB PDF attachment to a few people asking for final comments is completely reasonable.
What would be unreasonable is then to email the finished 10MB file to your list of supporters. Instead, you could create a lower-resolution or even text-only version of the PDF, put that on your website, and email a link to the file, perhaps with a little indicator of the file size like "[1. Why worry about file size when it only takes someone on high-speed broadband 15 seconds to download a 10MB file?
A 10MB download on dial-up might take nearly an hour. And older broadband connections or in rural areas the download speed might be kbps and the transfer still takes several minutes. Even on the fastest broadband, uploading is often limited to kbps, so if you expect a 10MB file to be retransmitted, that is likely to be slower than expected. A large file on its own may be no problem, but when multiplied by the size of the audience it can cause bandwidth problems that affect internet service providers and other users.
GreenNet doesn't limit bandwidth, but it is subject to a "fair use" policy. Once downloaded, larger files are harder to manipulate. Large emails can slow down access to an email inbox, and will increase the size of mailbox files on the recipients' computers. Large image files on a web page often have to be scaled by the browser software and mean navigating and scrolling through the page can be slow and erratic. There are other things that can cause slow "rendering" of a page, such as Javascript or a complex website "back-end".
Then there's the backup. If someone intends to keep the document or image or archives all email, it might be replicated on backup media many times over. People may also be reluctant to keep files that consume more storage than they are worth, and so delete them.
It's still 15 seconds, even if it's a background download. Some of us get impatient waiting for the computer for more than half a second. In short, the "kilo-", "mega-", "giga-" and "tera-" prefixes are similar to their use in any other unit of measurement, like metres or watts:.
To confuse matters, "1 KB" or "1K" is used by many computer people to mean bytes, which is a convenient number in binary, and memory or disk is often allocated by operating systems in units of
