What are the advantages of using a travelers check?
Traveler's checks offer several advantages, including enhanced security, as they can be replaced if lost or stolen, unlike cash. They are widely accepted in many places, making them a convenient alternative to carrying large amounts of cash. Additionally, using traveler's checks can help with budgeting, as they can be pre-purchased in specific amounts, allowing travelers to manage their spending more effectively. Lastly, they often come with a fixed exchange rate, which can protect against currency fluctuations.
What do computers use to improve hard disk access time?
defragmenting your computer can improve the time it takes to load things, but by default, your computer most likely will not do this by itself
the hard drive itself has a cache which means it can return data faster without reading it from the disk
What is the part of the computer system that regulates the electricity the computer receives?
the power supply
What is the SAE term for the vehicle computer?
The Society of Automotive Engineers (SAE) bulletin, J-1930, standardizes the name as a power-train control module (PCM).
How do you convert 8mm tapes to your computer hardrive?
by scanning of recording the film on a camcorder and digitalizing the tape

It is a program design that allows it to detect permutations of an original sample. This is typically done with anti-virus programs to detect behavior similar to known viruses. This allows an antivirus program with only 30,000 or so definitions to successfully stop over 1,000,000 different viruses.
What is the difference between batch processing Online Processing and real time processing?
The transactions are entered in batches by keyboard and stored in transaction files. These batches consist of thirty or so records which are given a batch control ID. The batches are then run through a validation process and to make sure the batches balance a computed total is compared with a manually produced total. This helps to ensure that all data is entered without error or omission. The actual updating of master files only takes place after verification and validation are complete. This means batch processing is often run overnight, unattended. A new master file is produced as a result of a batch processing run. The original master file is kept along with a previous version.
After processing the output is produced, and is usually printed media such as payslips or invoices, although this is changing with the advent of the web.
There is really no such thing as real-time. The best you will get is a few milliseconds from input to response. However such fast systems are used in critical systems that control aircraft or the manufacture of sensitive or dangerous compounds.
Online processing means users directly enter information online (usually, online, in this case, means online to a central processor, rather than its modern connotation of the Internet, but it could mean both!), it is validated and updated directly onto the master file. No new file is created in this case. Therefore, there is near immediate input process, and output. Imagine a cash dispenser transaction or booking a holiday at a travel agents or over the Internet. Compared with batch processing the number of transactions will be few.
Online comes in many different flavours such as centralised, distributed, time-share etc and the choice of architecture will depend on cost, speed needed, number of users, number of transactions and time needed for a response.

Why does usb go bad after about 6 meters?
Energy is required to move data across a wire. The longer the cable, the more resistance is encountered by the energy used to move the data. The low voltage of a usb port is progressively lost as it travels down the wire until there isn't enough to carry the signal.
