Monochrome Display Adapter Function Description The IBM Monochrome Display and Printer Adapter is designed around the Motorola 6845 CRT Controller module. There are 4K bytes of RAM on the adapter that are used for the display .~ buffer. This buffer has two ports to which the system unit's microprocessor has direct access. No parity is provided on the display buffer. Two bytes are fetched from the display buffer in 553 ns, providing a data rate of 1.8M bytes/second. The adapter supports 256 different character codes. An 8K-byte character generator contains the fonts for the character codes. The characters, values, and screen characteristics are given

  • CPU) the CPU Is the Brains of the Computer, and Is Also Known As the Processor (A Single Chip Also Known As Microprocessor)
    Central processing unit (CPU) The CPU is the brains of the computer, and is also known as the processor (a single chip also known as microprocessor). This electronic component interprets and carries out the basic instructions that operate the computer. Cache as a rule holds data waiting to be processed and instructions waiting to be executed. The main parts of the CPU are: control unit arithmetic logic unit (ALU), and registers – also referred as Cache registers The CPU is connected to a circuit board called the motherboard also known as the system board. Click here to see more information on the CPU Let’s look inside the CPU and see what the different components actually do and how they interact Control unit The control unit directs and co-ordinates most of the operations in the computer. It is a bit similar to a traffic officer controlling traffic! It translates instructions received from a program/application and then begins the appropriate action to carry out the instruction. Specifically the control unit: controls how and when input devices send data stores and retrieves data to and from specific locations in memory decodes and executes instructions sends data to other parts of the CPU during operations sends data to output devices on request Arithmetic Logic Unit (ALU): The ALU is the computer’s calculator. It handles all math operations such as: add subtract multiply divide logical decisions - true or false, and/or, greater then, equal to, or less than Registers Registers are special temporary storage areas on the CPU. They are: used to store items during arithmetic, logic or transfer operations.

  • Network Cable: Networking Cables Are Used to Connect One Network
    Network cable: Networking Cables are used to connect one network device to other or to connect two or more computers to share printers, scanners etc. Different types of network cables like Coaxial cable, optical fiber cable, Twisted Pair cables are used depending on the network's topology, protocol and size. The devices can be separated by a few meters (e.g. via Ethernet) or nearly unlimited distances (e.g. via the interconnections of the Internet). While wireless may be the wave of the future, most computer networks today still utilize cables to transfer signals from one point to another. Network card: A network card is a an adapter card, pc card, express card module, USB network adapter ,or flash card that enables a computer or device that not have networking capability to access a network. The network card coordinates the transmission and receipt of data, instruction , and information to and from the computer or devices containing the network card. Network cards are available in a variety of style. A network card for a desktop computer is an adapter card that has a port to which a cable connects. A network card for mobile computers and devices is in the form of a pc card ,express card module, USB network adapter, or a flash card. Network cards that provide wireless data transmission also are available. This type of card, sometimes called a wireless network card ,often has an antenna. A network card follow the guidelines of a particular network communication standard, such as Ethernet or token ring. An Ethernet card is the most common type of network card.
