In computer software a toggle is something that is either on or off and can be alternated between these two settings. The 3 good examples are the Bold, Italics and Underline settings that are found in many applications. Each of those are toggles. They are commonly used. With text selected you can click on their icon to turn the setting on and clicking on the icon again will turn it off. So whatever state it is in, using the icons or the keyboard command or menu options, you can switch between the two settings.
Why does ASCII use 8-bit to represent an English character?
Because that is the definition
ASCII represents Latin characters of the English alphabet (there are no English characters) the character set is called "Latin"
The 95 ASCII graphic characters are numbered from 0x20 to 0x7E (32 to 126 decimal). The space character is considered a non-printing graphic

Why fiber optic cable is better than twisted-pair and coaxial cable?
Because fibre sales having a high capacity and maximum bandwidth compared with twisted pair cable and coaxial cable. It's your choice to buy it from online stores or offline. if you want it online many websites offer online fibre cables. Check fibre sale website its good I also use this product.
How many Letters per bytes in a word?
On a 16 bit i80386 machine a nibble represents 4 bits or half of a byte. A byte represents 8 bits. A word represents 16 bits or 2 bytes. On 32 bit machines the DWORD(double word) is available and represents 32 bits or 4 bytes. On the newer 64 bit machines a QWORD represents 64 bits or 8 bytes of data. QWORD stands for QuadWord or Quadruple Word. On modern computers, a single character consumes 2 bytes of data in memory. So the word cat would consume 6 bytes. These are known as DBCS or double-byte character sets.
Is burning a DVD the same as writing a DVD?
Yes. DVD writers are capable of writing to ("burning") blank DVDs, and CDs
as well.
However, you cannot use a CD burner to burn a DVD, and in some cases read it.
Here's the chain of command:
- Blu-ray
burner - burns to Blu-ray
discs, DVDs and CDs
- DVD burner - Burns to DVDs and CDs
- CD burner - burns only to CDs
What the different between synchronous and asynchronous?
In asynchronous transmission , the receiver and the transmitter each use their own clock signals so its not possible to know when a word starts and stops.
while in synchronous , the receiver and the transmission have common clock signals.
Why is the process of starting up the computer called booting?
The word "boot" or "booting" comes from the concept of bootstrapping, or pulling oneself up by the bootstraps. Before PC's, computer operators would run a program called the bootstrap loader. This loader did the initialization that is now automatic. The process became known as bootstrapping and later booting.
Relational Data Base Management System?
The word relational is also used somewhat inappropriately by several vendors to refer to their products as a marketing gimmick. To qualify as a genuine relational DBMS, a system must have at least the following properties (Note 1):
1. It must store data as relations such that each column is independently identified by its column name and the ordering of rows is immaterial.
2. The operations available to the user, as well as those used internally by the system, should be true relational operations; that is, they should be able to generate new relations from old relations.
3. The system must support at least one variant of the JOIN operation.
Although we could add to the above list, we propose these criteria as a very minimal set for testing whether a system is relational. It is easy to see that some of the so-called relational DBMSs do not satisfy these criteria.
We begin with a description of Oracle, currently one of the more widely used RDBMSs. Because some concepts in the discussion may not have been introduced yet, we will give references to later chapters in the book when necessary. Those interested in getting a deeper understanding may review the appropriate concepts in those sections and should refer to the system manuals.
What factors affect the speed of microprocessor?
There are countless factors that affect CPU speed, but here are a few:
- Temperature
- Ventilation
- Cooling
- Overclocking
- Motherboard bus-speeds
- Type of processor (32-bit, 64-bit, reduced instruction-set, etc)
What is a collection of computers connected together called?
It is called a network. If there are computers are connected to each other in the same building or immediate area, then they are considered to be part of a Local Area Network (LAN). If they are connected to other LANs around the world, then they are part of a Wide-Area Network (WAN). A famous WAN many are familiar with is the Internet.
there are 896000 kb in an mb and 896 mb is 104 mb away from 1 gb
Difference between public and private key?
Examples of a private organisation: McDonalds, Topshop, The Trafford Centre.
It is an organisation that is owned privatly by someone and who has to sell a product or provide a service to make their money.
Examples of a public organisation: The police, The Fire service.
It is an organisation owned by the government to help the public, it is not owned privately.
What does the term user friendly mean?
It simply means - the software has been designed so that the 'end user' (you & me) doesn't have to think too hard to actually use it. Some software (especially in the engineering trade etc) - requires at least a working knowledge of the subject in order to use the program.
What are specialized applications?
There are many types of specialized applications. Many applications are specialize in the engineering industry. The space industry also requires many specialized applications.
What is basic computer maintenance?
This is where the user maintains the computer without it being on the systems scheduled
list of things to do.
EG. Checking all the components are in working order
Advantages and disadvantages of management information system?
A good information system allows the user to access, understand and respond to information quickly and effectively. Whenever necessary, users can get the most accurate information needed to do an activity. A good information system also offers users a variety of ways to change and present information, as well as perform different tasks.
Information systems may not always function properly. This happens for a number of reasons. Systems break down, interrupting smooth operations and causing customer dissatisfaction. For instance, customers may be charged for the wrong services or for merchandise that they did not order. Also, defective information systems can deliver the wrong information to other systems, which could create further problems for the company and its customer

What is processor cache memory?
Processor cache is intermediate memory between the processor itself and main memory (RAM).
Because processors can read data so much faster than main memory, the speed of a processor would essentially be limited to the speed of RAM if we couldn't find a way to increase the efficiency of accessing data in main memory. Caches, which have a much lower access time than RAM, help to mitigate this problem.
Caches work on the principle of spacial locality. That is to say, they use the idea that if you access a location in main memory, then it is highly likely that the next memory location you want to access is very close to where you are. When you access main memory, the cache will actually pull in a "chunk" of data (often called a "cache line") in the hope that the next time you try to access data it will already be in the cache.
Typically there are two levels of cache (though with the increasing popularity of multi-core processors, three levels of cache are becoming more and more necessary).
The first level of cache (L1 cache) is what is directly accessed by the processor and is therefore the fastest (and most expensive) cache. L1 cache is usually split into two parts: data cache and instruction cache. The instruction cache holds the instructions of running programs that the processor needs to execute. The data cache holds the data being used by current instructions.
The second level of cache (L2 cache) is where the L1 cache pulls in information from. L2 cache is slower than L1 cache, but is more affordable and can be much larger than L1. With the exception of L3 caches mentioned above, this is the cache which pulls information in from main memory.
