  1. 1. Z Current Trends and Issues in IT Subject Code: COMP131 By: Marlon Jamera Email: mjdesignexpress@gmail.com
  2. 2. Z Scope of the Lesson Hardware Technology Trends Input Technologies and Trends Output Technology Trends Storage Trends and Trade offs.
  3. 3. Z Learning Outcomes By the end of the lesson, you will be familiar with the current trends and issues in IT. Identify what the input technology trends are. Identify what the output technology trends are. Explain what the uses of the hardware trends are. Integrate the trade offs of the storage trends.
  4. 4. Z Infrastructure Components IT Infrastructure: Provides platform for supporting all information systems in the business and the society. Computer Hardware Computer Software Data Management Technology Organizes, manages and processes business data concerned with inventory, customers and vendors.
  5. 5. Z Infrastructure Components Network and Telecommunications Technology Technology Services E.g. consultants for system integration with legacy systems.
  6. 6. Z Infrastructure Components Figure 1-1 A firms IT infrastructure is composed of hardware, software, data management technology, networking technology, and technology services.
  7. 7. Z Types of Computers Computers come in different sizes with varying capabilities for processing information. FLOPS (Floating Point Operations per Second) PDAs, handheld mobile devices. PCs Workstation More powerful mathematical and graphic- processing capabilities than a PC.
  8. 8. Z Types of Computers Servers Type of midrange computer Support computer network, sharing files and resources Provide hardware platform for e-commerce Mainframes Large capacity, high performance computer that can process large amounts of data very rapidly. E.g. used by airlines for thousands of reservations per second.
  9. 9. Z Types of Computers Supercomputer More sophisticated computer used for tasks requiring extremely rapid and complex calculations with thousands of variables and millions of measurements Used in engineering, scientific simulations, military/weapons research, weather forecasting. Grid Computing Power of geographically remote computers connected into single network to act as a virtual computer
  10. 10. Z Types of Computers Client/Server Computing Form of distributed computing Splits processing between clients and servers Clients: User point of entry. Servers: Store and process shared data and perform network management activities.
  11. 11. Z Types of Computers Client/Server Computing (cont.) Two-tiered client/server architecture Uses two types of machine Multi-tiered client/server architecture Balances load of network over several levels of servers. E.g. Web servers and application servers
  12. 12. Z Client/Server Computing Figure 1-2 In client/server computing, computer processing is split between client machines and server machines linked by a network. Users interface with the client machines.
  13. 13. Z A Multi-tiered Client/Server Network Figure 1-3 In a multi-tiered client/server network, client requests for service are handled by different levels of servers.
  14. 14. Z Input, Output and Storage Technology Input Devices: Gather data and convert them into electronic form. Keyboard Computer Mouse Touch Screen Optical Character Recognition Magnetic Ink Character Recognition Pen-based Output Digital Scanner Audio Input and Sensors.
  15. 15. Z Input, Output and Storage Technology Output Devices: Display data after they have been processed. Monitor Printer Audio Output Information systems collect and process information in one of two ways Batch Processing: Transactions stored for predefined amount of time, then processed as a group Online Processing: Transactions processed immediately.
  16. 16. Z Hardware Trends The emerging mobile digital platform Cell phone, Smartphone Netbooks and Tablet Computers E-book Reader Nanotechnology Creating computer chips and other devices thousands of times smaller through manipulating individual atoms and molecules.
  17. 17. Z Hardware Trends Example of Nanotubes: Figure 1-4 Nanotubes are tiny tubes about 10,000 times thinner than a human hair. They consist of rolled up sheets of carbon hexagons, have potential uses as minuscule wires or in ultra small electronic devices, and are very powerful conductors of electrical current.
  18. 18. Z Hardware Trends Cloud Computing A model of computing in which firms and individuals obtain computing resources over the internet. Cloud infrastructure as a service Cloud platform as a service Cloud software as a service
  19. 19. Z Hardware Trends Figure 1-5 In cloud computing, hardware and software capabilities are provided as services over the Internet. Businesses and employees have access to applications and IT infrastructure anywhere at any time using an Internet-connected device.
  20. 20. Z Hardware Trends Autonomic computing Development of systems that can configure themselves, heal themselves; E.g. Self-updating antivirus software.
  21. 21. Z Hardware Trends Virtualization Process of presenting a set of computing resources so they can be accessed in ways that are unrestricted by physical configuration or geographical location. Server Virtualization: Running more than one operating system at the same time on single machine.
  22. 22. Z Hardware Trends High performance and power-saving processor Multi-core Processors Integrated circuit with two or more processors. Enhanced performance, reduced power consumption and more efficient simultaneous processing of multiple tasks. Power-efficient processors Low Power consumption essential in mobile computing.
