What does Y2K stand for?
What does Y2K stand for?
The flaw, faced by computer programmers and users all over the world on January 1, 2000, is also known as the “millennium bug.” (The letter K, which stands for kilo (a unit of 1000), is commonly used to represent the number 1,000. So, Y2K stands for Year 2000.)
What does Y2K mean in fashion?
year 2000
Why is the world ending in 2038?
This time the problem was being caused by Linux computers counting the time in seconds, starting from January 1, 1970. On that fateful date in January 2038, the number of seconds would have exceeded the value that could be stored in a single 32-bit integer, causing computers to lose track of time.
Who was president during Y2K?
Today, President Clinton signs the Year 2000 Information and Readiness Disclosure Act, that will help provide businesses, governments, and other organizations the necessary informational tools to conquer the Y2K computer problem.
How many bytes is a timestamp?
10.9 Date and Time Data Type Representation
| Type | Storage before MySQL 5.6.4 | Storage as of MySQL 5.6.4 |
|---|---|---|
| TIMESTAMP | 4 bytes, little endian | 4 bytes + fractional-seconds storage, big endian |
| DATETIME | 8 bytes, little endian | 5 bytes + fractional-seconds storage, big endian |
What is the storage space required by datetime?
DATETIME is packed more efficiently, requiring 5 rather than 8 bytes for the nonfractional part, and all three parts have a fractional part that requires from 0 to 3 bytes, depending on the fractional seconds precision of stored values.
Are the basic units of data storage?
Byte, the basic unit of information in computer storage and processing. A byte consists of 8 adjacent binary digits (bits), each of which consists of a 0 or 1. The string of bits making up a byte is processed as a unit by a computer; bytes are the smallest operable units of storage in computer technology.
Which is the smallest storage device?
The original device — dubbed “atomristor” by the researchers — was at the time the thinnest memory storage device ever recorded, with a single atomic layer of thickness.
Which has storage capacity?
Storage capacity refers to how much disk space one or more storage devices provides. It measures how much data a computer system may contain. For an example, a computer with a 500GB hard drive has a storage capacity of 500 gigabytes.
How many atoms are needed to store a bit?
Researchers have successfully stored a single data bit in only 12 atoms. Currently it takes about a million atoms to store a bit on a modern hard-disk, the researchers from IBM say. They believe this is the world’s smallest magnetic memory bit.
What is a non volatile storage device?
Hard disks are nonvolatile storage devices that are used to store and retrieve data quickly. Nonvolatile storage is physical storage media that retain the data without electrical power. This means that no data is lost when the computer or device is powered off.
Is ROM volatile memory?
RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
Which one is non-volatile storage?
Examples of non-volatile memory include flash memory, read-only memory (ROM), ferroelectric RAM, most types of magnetic computer storage devices (e.g. hard disk drives, floppy disks, and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.
Why does Ram lose memory when turned off?
Because the RAM is connected directly to the CPU via the memory bus, the CPU can access data stored in RAM very quickly. For this reason, RAM is used to store data loaded by active programs and the operating system. RAM is a type of volatile memory because it will lose its data if the power is turned off.
What happens to anything in RAM when you power off your computer?
RAM is often referred to as volatile memory, because anything contained in RAM is considered lost when a computer is switched off. Indeed, all data is lost from RAM when the power supply is disconnected; so it is volatile in this context. They carried out RAM dumps immediately after switch off at 5, 15 and 60 minutes.
