Briefly explain the similarities and differences between human beings and computer systems. Both can move: Humans can move from one place to another so does computers (robots); they are able to make movements Both can process data into information: Computers have processors that can encode and decode data into something meaningful called information. Humans also have the brain that can process, reason (logic) and manipulate any form of data into something meaningful. Both have Memory and Storage media: Computers have a Random Access Memory, Cache, Registers, Buffers, hard disks that can keep data temporarily or permanently. Humans have a brain that can do the same. Both can retrieve and transmit data: Computers can pass information from one machine to another, humans can pass messages to one another Both have ability to learn: Computers have artificial intelligence (a system they are programmed onto to gimmick human intelligence such as learning and prediction). Humans are naturally

The computer lab rules and regulations differ from one place to another, from one school to country, class or region. Computer labs in Kenya are no different in this criteria. A computer lab is a room set aside to enhance proper learning of computer studies and host the facilities needed to pursue the study. Just like other labs, in the computer lab, accidents happen thus all students should respect and use the computer lab diligently to the benefit of all students and the school community. The following regulations are commonly used or pronounced when a computer lab has been put into place. The computer Lab Rules and Regulations Keep off foods and drinks Do not enter the computer lab with muddy shoes Do your work quietly Respect other students the same way you would like it to happen to you Do not send your work to the printer before consulting the computer lab management team Don't change the computer settings without permission from your teacher/management Organize your files ne

HISTORY OF COMPUTING Before 1900, most data processing was done manually using simple tools like stones & sticks to count and keep records. Around 2000 years ago, Asian merchants came up with a special calculating tool called Abacus that could be used to calculate large figures. An Abacus is made up of a rectangular frame and a crossbar at the middle.  It is fitted with wires or strings running across from the frame to the crossbar. How to represent a number using an Abacus. Each bead in the lower row has a value of 1, while each bead in the upper row has a value of 5.  To represent a number, the bead is moved to the crossbar.  Those beads away from the crossbar represent zeros. The Figure below represents the number 6908 (Six thousand nine hundred and eight). After Abacus, the first machine that is usually regarded as the forerunner of modern computers was named the Analytical Engine, and was developed by an English mathematician called Charles Babbage. In 1939, Pr

Basic Computer Practices and Maintenance Skills for Starters –Part two Adjusting system volume To adjust the volume for multimedia playback devices Open Sounds and Audio Devices in Control Panel . On the Audio tab, under Sound playback , click Volume . In the Master Out dialog box, drag the Volume slider for the appropriate device up or down to increase or decrease the output volume. Installing drivers A device driver or software driver is a computer program allowing higher-level computer programs to interact with a hardware device. A driver typically communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device, once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware-dependent and operating-system-specific. In
