  3. 3. THE COMPUTER SYSTEM A computer is a general-purpose machine that processes data. The data is processed according to a set of instructions known as programs. The computer and all equipment attached to it (the central processing unit, input, output, and memory) are called hardware. The programs are known as software. Computer Virus A computer virus is a piece of code that is secretly introduced into a system in order to corrupt it or destroy data. Often viruses are hidden in other programs or documents and when opened, the virus is let loose. Anti-virus Software This is software that is designed to detect and prevent them from infecting your Machine.

  4. 4. Maintenance of Computer (PC) 1. Computer should be placed in a cool or conducive environment 2. Install anti virus 3. By making use of UPS (Uninterrupted Power Supply) 4. By making use of stable stabilizer 5. Cover your computer to avoid dust (using system cover) 6. Have a permanent engineer 7. Shutdown properly 8. Rug or carpet the floor Function of each major computer component Each different part in a computer has a different task to perform, just as each part in an automobile has a job to do, and each part works differently in order to get the job done. The Processor “CPU” The processor is known as the brain of the computer. It adds, subtract, multiplies and divides a multitude of members. There are two parts of processor that do the math. The first part is called the Integer Unit. Its job is to take care of the “easy” numbers, like -5, 13, ½ etc its mainly used in business applications, like word processors, spreadsheets, and the windows desktop. The second is called Floating Unit its job is to take care of the really hard numbers, like the square root of 3, pi, “e” and logarithms. This part of the CPU is mainly used in 3D games, to calculate the position of pixel and image. The Hard Drive “HD” The hard drive is simply a multitude of metal that spin around inside your computer, with heads that moved around those disks. The reason for using a Hard drive is because hard drive is the only part inside a computer that storage data, setting, programs and operating system while the computer is off. DE-CROWN 07032588860/08020317355 4
  5. 5. The Random Access Memory (RAM) RAM is easily confused with hard drive because both store data. Te two are actually very different. The Ram is a chip that holds data, only as electricity flows through it. Ram is used as a interface between the Hard Drive and the processor. Cache “L1, and L2” The cache is high speed Ram. It stores commonly used data and instructions from the processor so that it doesn’t have to go the slower Ram to get it. This is why the modern day computer is so fast. Without it, your computer would be running terribly slow. The cache is divided into two (2). L1, range in size from 32KB to 128KB. It is split in half and resides with in the CPU core next to the integer and floating point unit. The first half stores commonly used data, and the second half stores common instruction that the processor carries out on the data. L2, is for data only. Some L2 caches are on the motherboard. Others are on a special cartridge with the CPU. Newer L2 caches are in the CPU core, with the L2 caches. The Chipset The chipset is the boss inside the computer. It controls communication between the components. Storage Device Memory devices are used to store data in the computer. The devices are classified into two, namely: Internal Memory and External Memory. * Internal Memory Internal memory is made up of two parts namely:  Read Only Memory: (ROM) (cannot be removed)  Random Access Memory (Can be removed) * External Memory DE-CROWN 07032588860/08020317355 5
  6. 6. The need of external memory arises as a result of the limited capacity of the memory. Hard disk and floppy disk are two main examples of external memory. Hard Disk: The hard disk, also called Fixed Disk, is the system unit. It has disk drive but the drive (i.e. a place through which the disk is inserted into the computer) is invisible because it is inside the system unit. Most of the programmed we use day- in day-out are stored in the hard disk. It is usually between 20MB(Mega byte) and 2 or 3.5GB (Giga byte) Floppy Disk (Also Called Floppy Diskette or 3½ Floppy Disk) This can be also be described as external memory because it can be removed and kept somewhere by the user. It can be described as high density or low density. It can also be described as 3½ Floppy “A”. It can be inserted into the computer system. Note: A Floppy diskette should not be exposed to heat and magnetic field. It must not be touched and therefore must always be kept in protective packet. Visual Display Unit The VDU also called the screen, monitor, cathode ray tube (CRT) can display both alphanumeric (letter and numbers) and graphics (pictures). The Monitor can be of two types:  Monochrome  Colour Monitor Classes of Computers Computer can be classified or typed, many ways. Some common classifications are summarized below 1. Micro Computer (Personal Computer) Micro computers are the most common types of computers in existence today, whether at work, in the school or on the desk at home. This computer includes  Desktop Computers  Laptop and Notebook Computer DE-CROWN 07032588860/08020317355 6
  7. 7.  Tablet PC  Palmtop Computers  Personal Digital Assistance (PDA)  Programmed Calculator 2. Micro Computers (Midrange Computer) This is a class of multi-ser computers that lies in the middle range of the computing spectrum, in between largest multi-user systems (mainframe computer) and the smallest single-user system (micro computers or personal computers) Examples of are: Higher-end SPARC Power and Itanium – Based system from sun micro systems, IBM, and Hewlett Packard. 3. Mainframe Computer This was created to distinguish the traditional, large, institutional computer intended to service multiple users from the smaller, single user machines. These computers are capable of handing and processing very large amounts of data quickly. They are used in large institution such as banks and large corporations. Classes of Functions 4. Servers: Usually refer to a computer that is dedicated to providing a server. For example, a computer dedicated to a database may be called a database server “file server” manager a large collection of computer files. 5. Workstation: Are computers that are intended to serve one user and may contain special hardware enhancements not found on a personal computer 6. Embedded Computer: Are computer that are part of a machine or device Embedded computer generally execute a program that is stored in DE-CROWN 07032588860/08020317355 7
  8. 8. non-volatile and memory and is only intended to operate a specific machine or device 7. Super Computer: This is focused on performing tasks involving intense numerical calculations such as whether forecasting, fluid dynamics, nuclear simulations, theoretical astrophysics, and complex scientific computations Printers Printers are used to print the output on paper. The output on paper is called hard copy output while the output displayed on the screen is called softcopy output. Printers are classified into two: Non-Impact Printers and Impact Printers. MICROSOFT WINDOWS Introduction Windows has always been amazing graphical environment. Windows advances utility and facility so that whether you are a beginning or advanced user you can benefit from the new features, interface, networking capabilities, and so on.

But if you want to be able to reopen your work later, don’t forget to save it properly on a disk! Saving a Document After creating a document, select Save or Save as from the file menu .click on Save As if you are saving your document for the first time. By default, most files have the name untitled or on name at all. Therefore you should select an appropriate name the first time you save a document. If necessary, browse through the drives and name the select the place where you want your file saved. Wait to make a back up of your document in the folder where your original document is stored. In order not to overwrite the existing file, you will have to rename it. Please note that if you select the Save command afterwards, the document with the new name will be updated and not the original document. Wait to save your file in another folder or in another disk. You don’t have to change the file name but you will have to select the destination drive or folder in the Save in; section. Click on save if you want to keep all modifications you made to the active document. Benefits of the Information Technology (1) Data processing becomes faster and processed data more accurate. (2) Production of better quality information. (3) Data and information are more secured as mot if not all of them are stored on computer or computer related storage devices. (4) Reduced accommodation requirements since less paper files are needed. (5) Neater office also because less paper files are needed. (6) Lower office operating costs on the long run. Computer Network and Configuration Computers may be set up in various configuration and these may include among many: (1) Stand Alone: Where one complete computer system exist independently and is used without connection to or interaction with any other ones. DE-CROWN 07032588860/08020317355 15
  16. 16. (2) Network: Where two or more independent computer systems are inter- connected such that they can transmit and share their resources among themselves. A computer network is defined to be a set of autonomous, independent computer systems and other system components interconnected usually over long physical distance so as to permit interactive resource sharing between any pair of systems. The idea behind computer network is to provide computational power and might otherwise be impossible, to distribute computational loads more efficiently and to provide a sharing of computational facilities. Computer can be connected to one another either over geographically distant places via data transmission links or over a short distance i.e locally, through the use of internal cable. Two or more computers need to communicate with one another so that data processing work can be shared. Communicating with each other also enables the computers to obtain data and programs from one another. The commonest types of computer-to-computer links are micro-to-mainframe, micro-to-mini, micro-to-micro and in a few cases mainframe can be linked to another mainframe. COMPUTER VIRUS Computer virus is a computer program (usually a few statements) which is intentionally designed to destroy other programs, data and/or files. The virus has the ability to clone and hide itself and copies itself in the computer systems. Viruses can attack the boot sector of the computer. Some are files and memory resident. Apart from the virus, there are other malicious programs that case problems for the user. These are bomb, Trojan horse and a worm. Both virus and these other programs exhibit the following properties. Source of Computer Virus o Floppy Disc DE-CROWN 07032588860/08020317355 16
  17. 17. o Removable hard discs o Cartridges o Magnetic tapes o Optical discs o Modems o Pirated software o Demonstration discs. o Magazines or textbook discs Danger of Viruses • The following are some of the consequences of viral attack: • Loss of data • Loss of programs • Corruption of data • Corruption of program • System malfunction e.g. failure ton boot • Program failure e.g. inability to load • Anxiety Prevention of Virus  The following steps should be taken in order to prevent viral infection:  Check all software before installing them  Check all external storage media (diskettes) before using  Make backup copies of files on regular basic and check periodically, in case a recent backup contains infected files  Write-protect all systems and master diskettes  Install a reliable anti-virus program in your computer  Institute a procedure for checking your computers DE-CROWN 07032588860/08020317355 17
  18. 18.  Maintain contact with computer security experts for update news and information THE INTERNET The internet is a worldwide network of computers. Imagine a globe of the world with national boundaries. Then imagine millions of computers within each country linked together then imagine all the countries of the world linked together. That’s the Internet. This connection allows people tom share information like data, programmes, picture and music as well as storage disk. World Wide Web (www) Have you seen a spider web? That is what the World Wide Web is linkened to. It is simply a collection of multimedia documents and files the use multiple methods i.e. data sounds and pictures. These documents and files are connected with hyperlinks. The World Wide Web technology allows you to read text, view images and video in colour as well as hear sounds over the Internet. The world “World Wide” that preceedes the word “web” indicates that the Web page you are viewing can be view from anywhere in the world if the computer is connected to the Internet. What is a Web Site? A web site is a collection of Web pages maintained by the owner of the site. It is like having files containing information about your activities all in one collection. Every Web site has an address that is called a Domain name. There are Web sites, on virtually anything you can imagine; company, government, schools, churches, mosques, gamblers, governmental and non-governmental organizations, profession associations and youth associations may have a Web site. Among these are good Web sites. Develop the habit of keeping a lab on good Web site, you will learn a lot. See useful Web Sites. How Does The World Wide Web Work? The World Wide Web uses two software programmes to work. The Web browser software that runs on your computer and the Web server software that runs on the Web server. The Web browser software request information from the Web server DE-CROWN 07032588860/08020317355 18 13
  19. 19. and displays same on your computer screen. On the other hand, the Web server software stores Web server. The Web browser software that runs on your computer and the Web server software that runs on the Web server. The Web browser software request information from the Web server displays same on your computer screen. On The other hand, the Web server software stores Web pages (text, vide, audio) and responds to the requests from the Web browser and press enter key on your everything is OK, Yahoo home page is displayed on your computer screen. If the Web server is underpowered for the number of requests it receives, there will be a delay in serving up a page to the client. What is Internet Service Provider (ISP)? Internet Service provider (ISP) is an internet services company that connect people to the Internet for a fee. There are a couple of them around. Some Internet Services Provider offer dial up connection, while others offer wireless service. The services you choose depends on availability, location, cost and your needs. E-MAIL BASICS What is User Name? User Name is the name of the owner of the e-mail address. my name is Isaac Adekunle so my e-mail User Name is wiston09. e-mail User Name is followed by @ (at), then the name of the Web server where the server where the user maintains the account and lastly the suffix. so your e-mail address at yahoo will read something like your name mine is two people can not use same name as an e-mail address in one Web service. this is to avoid duplicity. for instance, you can not register because I have already registered it, but if you add any other thing before or after Winston09 for instance or it may be registered if not already taken. user name is usually written in small letters. E-Mail Etiquette Here are some basic rules or e-mail etiquette, commonly call Netiquette. DE-CROWN 07032588860/08020317355 19
  20. 20. (i) Always use subject line, this will help the mail recipient to have an idea of what your message is all about. (ii) Be brief in written, if the information you want to send is much, consider sending some as an attachment. (iii) Keep paragraph short and go straight to the point, it is hard to view long paragraphs. Remember most people will read your messages on the computer screen, so do not give them trouble reading your mail. (iv) Remember to check your mail for spelling errors before you send. What is Password? This refers to a key or code with which the user opens his/her e-mail box. With your password you can be sure that nobody – except technically proficient miscreants called hackers – will have access to your e-mail box. Passwords are case sensitive, that is, if you use an upper case (capital) letter to sign on, you must use upper case letter to open the box or vice versa. When you type your password, it will appear in asterisks to prevent others from reading it. Make sure you remember your password if you forget it, you will have difficulty opening your box. COMPUTER APPLICATIONS In the past, computers used to be enormous and expensive, required air conditions rooms and even whole buildings to house them. Nowadays, compact and reasonably priced yet powerful Personal Computers (PCs) are widely available and are becoming more common in everyday life. Computers in Business Many tasks in offices can be integrated using computers and this is referred to as office automation. This includes the use of word-processing, spreadsheet, database and e-mail applications. Computer in Homes DE-CROWN 07032588860/08020317355 20
  21. 21. Computer enables people to run a business from home and provide an essential link with the outside world. Some application that could be found on home computers are: (1) Word processing (2) Spreadsheets (3) Personal organizers (4) Music (5) Games (6) Internet access Computer in Libraries Computers can be found in libraries. Some applications of computers in the libraries are: (1) Library Books with Bundles (2) Library card with Bundles (3) Public Information Computers Computer in Hospitals Computers can be used to help medical practitioners manage their information. Some ways in which computers can be used in medical practice are: (i) To keep patients records, providing fast access to information. (ii) To access database information. (iii) To provide access to reference materials and journal in CD-ROM or the internet, keeping doctors abreast of word wide developments. (iv) Some computers software can be used for disease diagnosis and drug prescriptions. Computer in Banks Computer has brought about a widen gap between the old generation banks and the new generation banks in terms of computers and efficient delivery of services. The application of computer in carrying out banking transactions using electronic equipment is called ‘Electronic Banking’. DE-CROWN 07032588860/08020317355 21
