Computer Performance

The performance of a computer in terms of processing speed is related to
Processor Chip type
Primary Memory size, and
Clock Pulse.
The amount of information a computer can hold is dependent on its Secondary Memory (Hard Disk) size.
Usually the efficiency of a computer is related to the Processor Chip, with more advanced chips giving improved performance. The early PC processor chips were known as 8086, 286, 386 and 486. These are all now obsolete, and have all been superseded by the Pentium chip. The Pentium chip is available in a range of different speeds; e.g. there is the Pentium 166 and Pentium 200. The Pentium 200 is faster than a Pentium 166.
It is also important that the computer has sufficient random access memory i.e. RAM. If there is adequate RAM, the computer can be fast if configured well, and will be able to run many programs concurrently without running out of memory. A good office computer should have from 32MB of RAM.
 
Performance is also related to the speed of accessing the hard disk, for I-O (input output) operations. Hard disks come in different speeds, some IDEs are now faster, i.e. their rate of data transfer is greater. Improvements in hard disk technology have enabled the development of very large and very fast hard drives, at prices affordable for home and small office computing.The combination of a modern Processor chip, sufficient RAM and adequate Hard Disk storage space will produce good performance.
However, it should be noted that an upgrade of operating system or application software may degrade computer performance, as the general tendency is for each upgrade to require greater RAM and Hard Drive Resources.

Pen Input

Image
With pen input , users write, draw, and tap on a flat surface to enter input. The surface may be a monitor, a screen, a special type of paper, or a graphics tablet.  A light pen is handheld input device that can detect the presence of light. To select objects on the screen, a user presses the light pen against the surface of the screen or points the light at the screen and then presses a button on the pen.  A stylus is a small metal or plastic device that looks like a tiny ink pen but uses pressure instead of ink.   Some mobile computers and nearly all mobile devices have touch screens that recognize pen input. Most of these devices include a pressuresensitive digital pen or stylus. Pressure-sensitive digital pens typically provide more functionality than a stylus, featuring electronic erasers and programmable buttons. Computers and mobile devices often use handwriting recognition software that translates the handwritten lett...

Laptop, Tablets and Palmtop Computers

Image
The second type of computer that you may be familiar with is a laptop computer. Laptops are battery or AC-powered personal computers that can be easily carried and used in a variety of locations be a car, a taxi or airjet.    Example Laptop Computer The primary benefit of a laptop computer is its small size and easy portability . They use special screens, rather than the traditional bulky VDUs (Visual Display Units), which allows for longer battery life as well as portability. A laptop computer is sometimes called a notebook computer because of its size. Notebooks and Palmtop computers A newer term, “Notebooks”, simply indicates a VERY small laptop. These are especially popular with salespersons on the move or people giving presentations. While they tend to still be more expensive than an equivalent Desktop computer, they can now match the power of a Desktop computer. Palmtops are even smaller computers which can literally...

Measuring Memory

Image
Information is stored in the form of bytes.   A byte is a unit of memory in a computer and this byte represents either a character e.g. B or two digits e.g. 12.   These bytes are formed from bits.   Bits, or Binary Digits, may have one of two values.   These are represented by 0 or 1, true or false, but will actually be the presence or absence of magnetisation. Relationship between Bits, Bytes, Kilobytes, Megabytes and Gigabytes A Bit is the smallest element of data storage.   Bits grouped together form bytes.   With the ASCII code a combination of 8 bits form 1 byte.   For example when you type a letter ‘a’ the computer will understand that as a combination of zeros and ones e.g. 01100001.   The following indicates the relationship between different data units 8 bits = 1 byte 1024 (2 10 ) bytes = 1 Kilobyte 1 048 576 (2 20 ) bytes = 1024 Kilobytes = 1 Megabyte 1 073 741 824 bytes = 1024 Megabytes = 1 G...
