God created human beings for the following reasons:

  1. To know Him

  2. To love Him

  3. To serve Him

  4. To be happy with Him forever

Our first parent, Adam and Eve enjoyed a life of complete happiness before they committed sin. They never knew what pain nor sorrow was until they disobeyed God. In short, both were perfect beings until they committed the sin of disobedience against God.

Disobedience may simple be defined as the failure to obey rules, command or someone in authority.

Adam and Eve were the first human beings to disobey God.

Adam and Eve were able to commit sin (disobey God's command) because God had given them that special gift of free will.

The events written in Genesis 3:1-13 presents the story of the first human disobedience.

Now the snake was the most cunning animal that the Lord God had made. The snake asked the woman, 'Did God really tell you not to eat fruit from any tree in the garden?'

Genesis 3:1

Moral Lesson: The devil can come in any form and can tempt any man, woman, boy or girl, as far as he or she is of the age of reasoning.

Sometimes, satan creeps into one's life by asking simple questions. Notice that the snake (satan) did exactly this when it approached Eve to tempt her. To this end, we need to be at alert prayerfully because the evil one can tempt any human in any situation, place and at any point in time

Computer hardware is the collection of physical parts of a computer system.

Physical parts of a computer are those parts that you can see and touch. It may also be referred to as the 'equipment of the computer'.

When the computer case is opened (with a screwdriver), one would see the different hardware components inside of it. It's important to state that some other hardware components are present outside the computer case; and these are termed peripherals.

Below are hardware components seen inside the computer case:

  • Motherboard

  • Central Processing Unit (CPU)

  • Graphics Processing Unit (GPU)

  • Power supply Unit (PSU)

  • Northbridge

  • Southbridge

  • Peripheral Component Interconnect (PCI) slots

  • Network Interface Card (NIC)

  • Random Access Memory (RAM)

  • Ventilation fans

  • Heat sink

  • Hard Disc Drive (external present)
  • Solid State Drive (SSD)

  • CMOS battery

  • Optical Disc Drives (external present)

  • USB port, PS2 port, Ethernet port and other ports

  • Expansion Ports / Slots

ICT

Hardware components seen outside the computer case are called peripherals. The peripherals are grouped into the following:

  1. Input devices: They provide information to the computer.

  2. Output devices: Brings out information from the computer.

  3. Storage devices: They store information or data.

Below are examples of some peripherals:

  • Keyboard (input)

  • Monitor (output)

  • Mouse (input)

  • Webcam (input)

  • Touch Pad (input)

  • Universal Serial Bus (USB) flash drive or memory card (storage)

  • Hard disc drive (storage)

  • Stylus (input)

  • Joystick(input)

  • Printer (output)

  • Speaker (output)

  • Headphones (output)

prepayment is somewhat an opposition to deferred payment. This is true because the concept of prepayment oversees that the buyer makes payment beforehand and must wait to enjoy whatever had been paid for after some significant time had elapse.

In short, you can think of a prepayment as 'paying in advance'. An example is when a tenant pays in advance to a landlord for an apartment yet to be used. Another example is an online payment for items yet to be received.

Commerce

Deferred payment is defined as a future payment eventually made after a buyer receives goods and services without an initial payment. Think of it as the: 'buy now, pay later' type of transaction.

From the perspective of the seller, the money yet to be received after the supply of goods or services is called an accrued revenue, unrealized revenue or accrued assets.

According to the buyer, the money yet to be paid after the delivery of goods or services is called an accrued expense. For instance, a company that owes employees salary can be said to have an accrued expense.

Commerce

For an item to be considered a commodity, it must satisfy three conditions. These are:

  1. It must be standardized. In the case of agricultural commodities, they must be in their unprocessed state.

  2. It must be usable upon delivery

  3. The price of a commodity item must vary.

A commodity market can therefore be defined a place where people buy and sell homogenous goods in large quantities.

Homogeneous goods are products that essentially have the same physical characteristics (or qualities) as similar products from other brands.

It is noteworthy to state that foreign currencies, data and bandwidth have all been included as part of today's commodity markets. In this regard, a commodity market will always have it's own set of rules and regulations.

If we have water of 100OC  in an aluminium cup whose temperature is the same as that of its surrounding; let’s say 22OC; We will observe the followings:

  1. The temperature of water inside the aluminum cup will begin to decrease from its initial 100OC.

  2. The temperature of the aluminium cup will increase from its previous 22OC.

  3. After some time, the temperature of the water, aluminium cup and the surrounding will become the same.

From the above instance, it can be deduced that the heat present in the water molecules are first transferred to the aluminium cup and subsequently to the surrounding.

Heat from water >> Aluminium Cup >> Surrounding

Meanwhile, understand that aluminium is a metal; and metals are good conductors of heat.

Eventually, the system (water and aluminum cup) together with the surrounding reaches the same temperature; and the heat transfer ceases. It is at this point that the water, aluminium cup and the surroundings are said to have reached a thermal equilibrium.

Please on the concept of heat and temperature here

Physics

Heat is never static. It is always transferred and thus: an object will increase its temperature by gaining heat energy from its surroundings while another object will simultaneously decrease its temperature by losing its heat energy to the surroundings. For this reason, we may also define temperature as:

The measure or ability of an object or substance to transfer heat energy to another object or substance.

The higher the temperature, the greater the ability of an object or substance to transfer heat. Conversely, the lower the temperature, the greater the tendency of an object to receive the transferred heat.

The point is: 'for heat to be transferred, we must have systems or objects or substances with varying temperatures

Physics

The Solar System - Len Academy

The average distance between the earth and the sun is about 149.6 million kilometers. It will take the earth 365 one-quarter days (or 1 year) to make a complete orbit (or revolve) round the sun. This process is termed the revolution of the earth.

The revolution of the earth is responsible for the seasonal changes we experience here (on earth). In Nigeria and Africa at large, these are the rainy and dry seasons. In Europe, these are spring, summer, autumn and winter seasons. Similarly, the United States of America have got the spring, summer, fall and winter seasons respectively.

Geography

Let's use algebra to explain the simple statement below:

I am a number. When you subtract 3 from me, the result is 9. what number am I ?

Of course we know the answer is 12. You probably guessed it from your mind because it was that simple. The truth is, We could have a much more complicated statement of such; and that is where algebra comes into play.

Now, to apply algebra in the above statement, we use letters or alphabets to represent the unknown number(s). So using algebra, we can write:

  • Let the number be y

  • y - 3 = 9

  • y = 9 + 3

  • y = 12
