What is the number of times per second the electron beam scans the monitor and recharges the illumination of each pixel?

the__________ is the number of times per second the electron beam scans the monitor and recharges the illumination of each pixel?

Does data refer to information gathered?

Data can refer to a set of any kind of information, but data is the plural of the singular word datum. In a sentence: "We downloaded these data today."

What is the difference between the three cache memory?

This question should be more specific so that someone can more easily and accurately assist you. However, i will attempt to answer your question assuming that your are asking about the L1, L2, and L3 cache memory types.

L1, L2 and L3 (or level 1, level 2 and level 3) are different memories seperate from the processor, but it is the memory more easiest and quickly accessible by the processor, or cpu. These memories are used by the processor to store common instructions, images..etc. so that it can easly and quickly access it whenever required to. First the processor checks the L1 cache memory (usually the level with the lowest amount of memory), if it doesn't find what it needs there then it searches through the L2 and then L3.

If what the processor needs isn't in the cache memory, then it will check the HDD and RAM.

Routing is a technique in which a network administrator programs a router to use specific paths between nodes?

Static routing is a technique in which a network administrator programs a router to use specific paths between nodes?

Is 5 MB a lot?

Not by today's standards. The average song file is at least 3 MB, so you could only put about 16 songs into 50 MB.

What is the role of a protocol?

internet protocols or web protocols provide a basis of data volumes across a wide range of networks. This includes the security of data transported or routed, authenticating client servers, ensuring data integrity and securing data privacy.

How do you abbreviate Bachelors Of Science information technology?

There are a few abbreviations for a Bachelor of Information Technology degrees. A few of the abbreviations are BIT, BInfTech, B.Tech (IT), and BE. (IT).

What is the role of CPU in the computer's functioning?

The CPU is the 'brain' of the computer. It is where all the searching, sorting, calculating and decision making takes place. The CPU contains a tiny quartz clock. Each time this clock 'ticks', one instruction can be dealt with by the CPU. So the more times this clock ticks per second, the more instructions the CPU can carry out and the faster things get done.

The speed of the CPU is measured in either Megaherts (MHz) or more commonly now in Gigahertz (GHz). A 1 MHz CPU can carry out one million instructions per second. A 1 GHz CPU can carry out 1 billion instructions per second!

A typical CPU installed in a computer today would run at around 3 GHz.

What are the difference between information processing cycle and information cycle?

"Data processing is simply the conversion of raw data into meaningful information through a process."

& Data Processing Cycle is described by following image

How many kilobytes is 2800 megabytes?

the term gigabyte is known as gb and megabyte known as mb. these are mainly units to measure memory capacity.means capacity to hold data. mb is smaller than gb. one gb contains 1024mb. so u can find it out like 280 mb contains (280/1024) equals to 0.203125gb

What are different types multiprocessor system?

A multiprocessor system is any device with multiple processors(processing cores).

These days, you can buy up to an 8 core PC, (apple's new mac pro) http://blogs.zdnet.com/Apple/?p=485

But most people with gaming PC's have at least a duo-core processor. They used to be very expensive, but now they are affordable. But you'll usually hear that term associated with PC or computing devices. It makes everything faster, especially multitasking.

How many characters are in 6 bits?

Theoretically, 64. However, it is rare that 6 bit character sets would be used. Bytes are 8 bit and is the most popular form of information interchange today.

What is the purpose of language translation utilities?

Language translation Utilities are a generic name for all those compilers that convert any programming language into machine code. Without them then the program would be unintelligible to the computer. I suspect that things like Printer drivers etc, could fall into this description also.

How computer CPU casing is made?

Computer Casinge are made according to sizes of Motherboards & devices required onto. These are available in many form factors(AT/ATX). Computer Cases usually contain SMPS (Power supply), Motherboard base plates, Switches (Power On/OFF, Reset) & light indicators.

In Windows XP Device Manager how do you uninstall a device?

You can't disable the device manager. However, only administrators have have the ability to change it. If you create a new account on your computer that doesn't have administrative abilities, then that suer won't be able to make any changes in the Device Manager.

How many characters can be represented by one 8-bit byte for example?

For Latin-based alphabets, normally one.

  • The English alphabet and some special characters (period, comma, newline etc.) fits into 7 bits
  • Most European alphabets (French, Swedish etc.) plus some more special characters (inverted quotes, copyright/euro/pound/yen symbols etc.) fit into 8 bits
  • Non-Latin languages like Russian, Hebrew, Chinese etc. may need two, three or four bytes (16-32 bits) per character or symbol.
To some extent the number of bits per character depends on the character encoding, the numbers above are based on US-ASCII (USA), ISO-8859-1 (Western Europe) and UTF-8 (global), arguably the most common encodings.

The type of input that is a set of instructions that direct the computer?

No - an input device is a device that provides data input to a computer. A keyboard, mouse, microphone, and Web cam are examples of input devices. A monitor and speakers are examples of output devices.

A set of detailed instructions given to a computer is called a program.

What power management standard is older than ACPI and has been mostly replaced by ACPI?

APM (Advanced Power Management) as WIKI answers it...

is an API developed by Intel and Microsoft which enables an operating system running an IBM-compatible personal computer to work with the BIOS (part of the computer's firmware) to achieve power management.

Name the part of the computer that stores all information and software?

The Hard Drive is the main storage unit in a normal, desktop computer. This is the only internal component in a standard computer that has information when the machine is turned off (all your saved files, the operating system (such as Windows), etc).

There are other components (such as RAM, or Random Access Memory) that store data, but this usually serves a special purpose, or is only at run-time.

What is the difference between parallel computing and parallel processing?

Parallel processsing ranges from instruction-level parallelism e.g. superscalar and VLIW to message-passing MIMD also called multicomputer, and also includes SIMD e.g. vector and array processing. Multiprocessing is specifically task parallelism, and is by definition shared-memory MIMD with multiple processor cores, sometimes multiple sockets.
