“Algorithms” are a set of well-defined finite sequence instructions used to complete a given task. Algorithms are used extensively in computer science, bio-informatics, mathematics and other sciences for calculation, data processing and related tasks.
"Bandwidth" refers to the capacity of data/information which can be transmitted through a channel (e.g. website, portal, server) in a given time interval. Bandwidth is usually measured in bits per second (bps).
“Broadband” refers to a telecommunications signal of greater bandwidth, in some sense, than another standard or usual signal (and the broader the band, the greater the capacity for traffic). There are various minimum bandwidths that have been used to define broadband, ranging from 64 kbit/s up to 4.0 Mbit/s. The trend is to raise the threshold of the broadband definition as the marketplace rolls out faster services.
“Computer” means any electronic device of computational machinery using programmed instructions which has one or more of the capabilities of storage, retrieval, memory, logic, arithmetic or communication and includes all input, output, processing, storage, software, or communication facilities which are connected or related to such a device in a system or network or control function by the manipulation of signals, including electronic, magnetic or optical and shall include any input, output, data storage, processing or communication facilities directly related to or operating in conjunction with any such device or system or computer network.
“Computer Network” means the interconnection of one or more computers through.
“Computer System” means a device or collection of devices including input and output support devices and excluding calculators which are not programmable and capable of being used in conjunction with external files, which contain computer programmes, electronic instructions, input data and output data, that performs logic arithmetic, data storage and retrieval, communication control and other functions.
“Data” means a representation of information, knowledge, facts, concepts or instructions, which are being prepared or have been prepared in a formalised manner, and is intended to be processed, is being processed or has been processed in a computer system or computer network, and may be in any form (including computer printout, magnetic or optical storage media, punched cards, punched tapes) or stored internally in the memory of the computers.
“Electronic Form” with reference to information means any information generated, sent, received or stored in media magnetic, optical, computer memory, micro film, computer generated, micro fiche or similar device.
“Electronic Record” means data, record or data generated, image or sound stored, received or sent in an electronic form or micro film or computer generated micro fiche.
“Government” means the Federal Government of Nigeria.
“Information Technology” encompasses all forms of technology used to create, store, exchange and use information in its various forms (business data, voice, conversation, still images, motion pictures, multimedia presentations and other forms including those not yet conceived).
“IP Address” is a number that is automatically assigned to your computer whenever you are surfing the Web
"Keyboard" is means of sending information to the computer. It has the same keys as a typewriter keyboard as well as some additional keys.
"Monitor" is the computer’s screen or display. Monitors come in sizes from 14 inch, 17 inch, to as large as Gateway’s 36 inch monitor.
"Modem" is a mechanical means of translating computer information or retrieving information from the Internet via a phone line. It needs communication software in order to work and can be attached internally or externally. Internet transmission can also take place over an ISDN line or the even faster T1 line. No modem is necessary for these types of transmission but you will need an ISDN adapter.
"Mouse" is an acronym for Manually Oscillating Utensil Sonically Engaged. It is the electronic finger of the computer. It is used to point at items in the window environment. The mouse arrow indicates your position on screen. It can change its shape depending upon your position on screen or the program you were using. In a word processor the mouse will appear as a flashing cursor or insertion point. Moving and clicking the mouse can move the cursor onscreen. The mouse has 2 buttons. The left button is used to send signals to programs. The right mouse button gives the user various menus. By double clicking the left mouse button, programs can be opened. A new mouse, the Intellimouse, allows the user to scroll a screen in a program using a center wheel.
"Ports" enable you to connect external output or input devices to your computer. The basic types of ports are:
Parallel ports can be used to connect printers, zip drives, video capture (such as Snappy), external hard drives, or digital cameras.
Serial ports could be used to connect all of the above except printers. In addition, there are some serial port mice.
PS2 ports are used to connect some types of mice. There are also places on your computer to attach a keyboard and s-video cable.
“Software” includes any program, procedure and associated documentation concerned with the operation of a computer system.
