BTE 1 week CLASS NOTES BTE 1st CLASS COMPONENTS: 1. Hardware 2. Infrastructure 3. Network 4. Database 5. Procedures 6. People How does IT impact organizations? 1. Book industry: we used to go to find hard copy, but nowadays EBook exist 2. Music industry: used to be on a store, now it is online. 3. Video industry: we see our favorite movies in programs such as Netflix, hulu, amazon prime. 4. Software industry: you rent and order packages which you can also pay annually 5. Automobile: how cars like for example chevy Wi-Fi integrated, new technologies in the industry. You are able to get reports from your car to your mobile device. 6. National defense Industry 7. Fashion industry 8. Education 9. Legal profesion IT Changes the managers job IT changes the way managers make decisions. -Managers have less time to make decisions (data change) -IT provides real time info -IT provides tools for analysis. Will IT eliminate jobs? -Yes it is going to in one hand: Jobs that where made by us now machines take place. Example customer service on the phone, a machine or computer contains intelligence and talks to you to help pay your bill are replacing humans. Deliverings: drones instead of UPS driver The IT is creating a competitive environment where people compete with machines -However there is a second part. More IT employees will be needed. It is also creating new job categories. Since it is a complicated job more people that know about this will be required. IT impacts employees at work: IT provides opportunities for people with disabilities. Audible screen tips for employees who are visually impaired Importance of information systems to society It has changed the way we work. ROBOTICS -Manufacturing -Hospitals -Farming operations Manufacturing: Roomba to vacuum Scooba to wash our floors Verro to clean our pools Looj to clean our gutters Healthcare: There are better and faster diagnoses Monitor critical ill patients Radiologist Robots that are use to remotely perform surgery’s 2nd CLASS Hardware CPU: brain of the computer every one need one. Primary storage: temporary storage, which is the RAM. Everything that needs to be operated by the computer goes to the ram to get it with the software. Secondary storage: permanent storage. The difference between the storage is one of them is more volatile than the other one. Secondary: NON-VOLATILE Primary: VOLATILE, without power you do not have anything. Input technologies: whatever computer uses to accept data and converts the data put it inside the computer. Converts it to a form that computer understand. Output technologies: the one that transform in what we people see and have a pleasant expierence understandable slides. Communication: There are many hardwares for making the data to flow from one end to another end. From Primary to the CPU for example. Types of computers: Servers: -Supercomputer: to any technology which provide the faster computation services at the time. - Mainframe computers: servers that normally are using organization and business to handle the network, very scientific operation, amazon, ebay. There are many mainframes Clients: need to connect to server -Microcomputers: PC laptops, notebooks, tablets Difference between Thin Client and Fat client: In front of a computer you are a thin client, looks like a normal PC no hard disk or software. You are pulling applications from a cloud. They are inexpensive and very light in weight. Many organization use them because cheap, application rely on network infrastructure, replace easily. Fat client system: any kind of computer that is in the network environment and has the capability of doing operation. Laptops: heavier, bigger size. Ther are different vendors Netbooks: very tiny devices, not powerful but where inexpensive nowadays don’t find them so much Tablets: advanced. Purchasing a Computer: personal decision: where are you taking it. Nowadays we have a lot of opportunities. Convertibles, flexible hardware. Depends on what do you want and need Input devices: Are divided into 3 categories: 1) Human data entry devices: keyboard, mouse, track balls, pointing sticks, touch pad, graphic tables, joysticks, touch screen, stylus, digital pen, web camera, voice recognition. 2 ) Gesture based input: wii microsofoft kinect gesture recognizition leap motion control 3) Source data automation: automatic teller machine atm magnetic strip reader point of sale terminals barcode scanners optical marc reader magnetic ink character reader optical character recognition sensors cameras radio frequency identificacion Output devices Monitors: touchscreen Chathode ray tubes, LCD, flexible displays, Organic light emitting diodes, retinal scanning displays (google glass), heads-up displays used for military like pilots and they can see the target, altitude etc. Printers: Laser Inkjet Thermal Plotters Voice output: electronic book reader, proyector Cpu: central processing unit. Most modern are micro processors 3rdCLASS Microprocessor. Data measures. Bits bytes and more. 1: means power on 0: no power off Circuits with 1 and 0 create the magic of a computer He wants us to memorize the scale. Organize the chart. Computer memory- Primary storage component. There is a constant communication between CPU and 1. Registers memory 2. Cache memory 3. Random acces memory RAM 4. Read only memory ROM 1 Registers: there is a problem with the register couple of error. It is even included inside the CPU is like a microscopically storage where we could find the essential thing the CPU will need to do the calculations needed. Limited amount of instructions an data. 2 Cache Memory: even the RAM is not the fast so this designer added a cache memory that is a high speed memory. Info that is going to be used. A closer storage that u know you will be use it and you can acces more adequeatly. Hard disk is slow compared to the ram and the Cache is so much faster. We cant create the RAM with the same materials as the Cache. The cost of the hardware is taking into considerations. 3 The RAM: part of the primary storage. Small amount of software. The ram has to hold a temporarily file. 4 ROM: read only memory. It is one of the most important chips, because it contains instructions when the power of the computer is turned off. It saves the info lost, is nonvolatile Secondary storage: 1 Magnetic tape 2 Magnetic discs 3 Solid state drives (more expensive) 4 Optical storage devices (cd, dvd) 5 Flash memory (usb drive, ipod) 3 SSD. Solid state drives: you can have the traditional hard disk which rotates and there is a mechanical part. And the SSD there is no moving, better use of energy. There is no temperature consequence, a bit more expensive but it is worth it. 5Flash Memory nonvolatile electronic storage devices that use less battery power and there are a lot of technology devices that use this Optical drives examples: you can buy separately. There are many examples: CD, DVD drives. We still use them because of the money, they are so much cheaper also cd are read only cannot be damage. DVD single layer single size single layer double size dual layer.. the data capacity it has changes. There is a laminated material in the DVD making it to store more data. Intel: multinational company, CPU chips and drives. CPU they have several forms Multiusers: many users at the same time are using the same resources. Sometimes you have to connect to a better server data and LINUX, UNIX, SERVER EDITIONS sophisticated softwares.
