STATE THREE SAFETY PRECAUTIONS YOU WOULD UNDERTAKE IF THE COMPUTER LABORATORY YOU ARE WORKING IN CATCHES FIRE1. RAISE ALARM
raising alarm alerts people who will rush for help and evacuation
2. RICH FOR THE FIRE EXTINGUISHER AND TRY TO PUT OFF
if you can reach for a fire extinguisher, try to put it off before it spreads further
3. TRY TO EVACUATE OTHER STUDENTS
try to evacuate other students using the procedure above. in most cases, use the emergence door if it exists and converge to the fire assembly point
4. IF YOU CAN SPOT POWER MAIN SWITCH, TURN IT OFF.
switching off power from the main switch will control its spread.
5. BEND LOW AS YOU EXIT TO AVOID SUFFOCATION FROM SMOKE.
when fire burns, it releases smoke which moves upwards in most cases unless influenced by wind, to avoid being choked by smoke, bend low as you exit and try to open windows for smoke to escape
STATE FOUR REASONS WHY SMALL COMPUTERS SUCH AS PALMTOPS SOMETIMES TEND TO BE MORE EXPENSIVE THAN DESKTOPS WITH THE SAME FEATURES.1. Small computers have high demand. This pushes prices high
Increase in demand increases the price of a commodity according to the laws of economics
2. The technology used to manufacture small computers is more advanced
New technologies always comes with a price

this increases demand
4. Have internal battery
Extra battery means more costs
5. They consume less power
drives up demand
6. They occupy less space
drives up demand
7. They have more multimedia capabilities and social media applications that drives up costs
this is extra cost
8. They can be used in the absence of power
increases demand
9. Some are made from precious metals such as gold
this factor increases prices
WRITE THE FOLLOWING ACRONYMS IN FULL1. AI
Artificial Intelligence
Artificial intelligence (AI) is a branch of computer science that emphasizes on the design and creation of intelligent machines that work, behave and respond like humans. Some of the characteristics that AI emphases on include: Speech recognition, Learning, visual perception, logical and arithmetic analysis and translation between languages.
2. ICT
Information and Communication Technology
Information and communication technology (ICT) is an advancement term for information technology (IT) that emphises on the technologies that provide access to information through the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage, and audiovisual systems, that enable users to access, store, transmit, and manipulate information.
3. ENIAC
Electronic Numerical Integrator And Computer
In 1942, physicist John Mauchly and John Presper Eckert proposed an all-electronic calculating machine. The result was ENIAC (Electronic Numerical Integrator And Computer), built between 1943 and 1945 — the first large-scale computer to run at electronic speed without being slowed by any mechanical parts. ENIAC was designed and primarily used to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory, its first program was a study of the feasibility of the thermonuclear weapon. In 1953, the Burroughs Corporation built a 100-word magnetic-core memory, which was added to the ENIAC to provide it with memory capabilities. By 1956, the end of its operation, the ENIAC occupied about 1,800 square feet and consisted of almost 20,000 vacuum tubes, 1,500 relays, 10,000 capacitors, and 70,000 resistors. It also used 200 kilowatts of electricity, weighed over 30 tons, and cost about $487,000.

4. UPS
Uninterruptible Power Supply
This is an Uninterruptible Power Supply. It cleans power as it enters into the computer by eliminating power surges and brownouts, it alerts the user when power goes off by producing a beeping sound and also keeps power to power the computer shortly after blackout so that the computer user can be able to save his/her work.
5. CPU

DESCRIBE THE FOLLOWING TYPES OF COMPUTERS: DIGITAL,DEDICATED, MAINFRAME COMPUTERS
This is a digital computer; computers that process data which is discontinuous (discrete) in nature. Yourdictionary.com further adds that, these are computers that process data which is inform of digits called binary digits represented by 0s and 1s
Mathsisfun.com describes discrete data as a type of data that can only take certain values such as the number of students in a class can only be represented as a whole number (this data can either be 40 or maybe 60 but it can never be 60.5 (this is continuous data)); continuous data is represented with values which can be rational such as the height of a person, weight or mass of a body or time in a race.
In addition Numerical Data can be Discrete or Continuous: Discrete data is counted while Continuous data is measured
Dedicated computers are general purpose computers however these computers are devoted to carry out one task only. For instance, a general purpose computer can be devoted for accounting in a bank or office, as a teaching aid in a school or for graphic editing in a studio or engineering firm.
When computers are classified according to their physical size, the word mainframe is always mentioned. This is a type of computer which is the second largest of all computers, only second after super computers but bigger than mini and micro computers. They are relatively more powerful in processing with large capacity in memory and storage but inferior to super computers if measured in capabilities.
STATE ANY FOUR DEVICES FOUND IN THE COMPUTER CHASSIS (SYSTEM UNIT)
The memory of a computer provides the computer with impermanent storage of data and information where the CPU can easily fetch from for processing
The mother board also called system board is the single largest unit in the computer chassis. It holds other devices that are attached to it such as resistors, capacitors, extension slots, ports, transducers, integrated circuits, central processing units, graphic adapters the list is long
A disk drive is any gadget in the system unit that acts as a container where permanent storage devices are put to read and write data or information. They include: hard disk drive, CD/DVD drive, SD drive, floppy drive, card drive, tape drive, zip drive etc.
The CPU is the single most expensive gadget in a computer and the most important of all other gadgets. It is also called a processor or a microprocessor (a terminology used to refer the CPU of micro computers). The main role of the CPU is to manipulate both logical and numeric data for something meaningful called information.
The power supply unit (PSU) is a gadget in the computer chassis whose main role is to convert electric power from alternating current to direct current for the consumption of the computer. It also supplies power to the system board, disk drives and internal loud speakers
This is a system fan, an aerator or air cooler propelled by a motor beneath. It cools down the heat sink that sucks heat from the CPU when processing takes place. Its is among the cooling systems in the system unit especially areas near the CPU and The power supply unit
This is a heat sink. It is made from a very good conductor of heat such as aluminium. It's main objective is to cool down the CPU by sucking heat and distributing it along it's surface area for cooling to take place.
Computer internal speakers are strategically installed in the system unit to amplify sound
Light emitting diode or LED is a bulb like gadget in the computer chassis whose main objective is to signal when power is on, when the CPU is processing and messaging of alerts and interruptions.
Graphic cards are gadgets in the system unit that provide the VDU - video display unit (screen/monitor) with images, color and information from the CPU for display via data interface media such as parallel and serial data cables. examples include VGA, SVGA, EVGA etc.
