Hard drive partitions
Hard drive partitionsGabriela_Technoteacher The document discusses the logical structure and partitioning of hard disks. It explains that the hard disk can be divided into logical partitions beyond its physical structure. This allows an operating system to access different sections of the hard disk as separate drives. There are two types of partitions - primary partitions that can directly contain an operating system, and extended partitions that allow creating additional logical drives beyond the 4 primary limit. Partitioning provides benefits like organizing data from multiple users, installing multiple operating systems, improving storage efficiency, and increasing data security through backups.

Bios
BiosEvans Lampi The BIOS (Basic Input/Output System) is low-level software that controls hardware and provides an interface between the operating system and hardware. It consists of device drivers stored in read-only memory on the motherboard and some expansion cards. The BIOS performs essential startup tasks like power-on self-tests and loading the operating system bootloader from disk. It provides an abstraction layer so operating systems and applications do not need device-specific knowledge.
HDD Partition
HDD PartitionAMZAD KHAN A partition divides a hard drive into logical sections for storing files and installing operating systems. There are three types of partitions: primary, extended, and logical. A primary partition can host an operating system, while an extended partition contains logical drives. The master boot record (MBR) stores information on partition locations and boots the system, but is limited to 4 primary partitions under 2.2TB each. The GUID partition table (GPT) replaces MBR and supports over 18 exabytes per partition. GPT uses a protective MBR for compatibility with older systems.
Disk partitioning

1.1.a mbr limits v2
1.1.a mbr limits v2Acácio Oliveira The document discusses the 2.2TB limitation of hard disk drives when using the master boot record (MBR) partitioning scheme. MBR partitioning allows a maximum disk size of 2.2TB due to its use of 32-bit values to describe partition sizes. This limitation can prevent accessing disk space beyond 2.2TB. The document explains that the Unified Extensible Firmware Interface (UEFI) specification defines a new firmware interface and supports the GUID Partition Table (GPT) scheme which uses 64-bit values, allowing for larger partition sizes and handling disks over 9 zettabytes in size. Only operating systems supporting UEFI and GPT are expected to boot from partitions larger than 2.2TB.

Lecture 9 file systemTanveer Malik The document discusses key aspects of file systems in Microsoft Windows, including NTFS, file permissions, quotas, Volume Snapshot Service (VSS), and offline files. NTFS is the standard file system for Windows operating systems. It supports metadata and advanced data structures. File permissions in NTFS control user access to files through assigning read, write, delete, and other permissions to users and groups. Quotas limit disk space usage. VSS allows taking backups of files even when in use through shadow copies. Offline Files syncs files to allow access when offline.
Lecture 6 internet services in network
Lecture 6 internet services in networkTanveer Malik This document discusses various internet services in a network including firewalls, network registration, wireless connectivity, wired internet, virtual private networks, and IP address and hostname management. A firewall establishes a barrier between an internal trusted network and an external untrusted network like the internet to control incoming and outgoing traffic. Network registration involves domain registration through an authorized registrar and provides security, disk space, IP allocation, and other services. A virtual private network creates an encrypted tunnel between a remote user and a company's private network to securely transmit data.
Lecture 5 software to control network
Lecture 5 software to control networkTanveer Malik Software defined networking is an approach that allows network administrators to programmatically control and manage network behavior dynamically through open interfaces. It provides an abstraction of lower-level network functionality. While OpenFlow was commonly used, many companies have adopted different techniques. The document also lists several free software tools that can be used to monitor and analyze networks, including GFI LanGuard, Microsoft Network Monitor, Nagios, and OpenNMS.
Lecture 4 sharing of resources on network
Lecture 4 sharing of resources on networkTanveer Malik Shared resources refer to computer data, information, or hardware devices that can be accessed remotely through a local area network. Common shared resources include files, data, printers, scanners, and multimedia. Sharing allows for collaboration on projects by enabling easy modification and updating of documents and files without emailing large attachments. However, security mechanisms must be implemented to prevent unauthorized access, and clients must have compatible operating systems or applications to access shared resources across different networks.
Lecture 3 transmission media
Lecture 3 transmission mediaTanveer Malik This document discusses different types of transmission media used to transmit data in networks. It describes transmission media as the physical pathways that connect devices and transmit information through cables or electromagnetic signals. It outlines common wired media like twisted pair, coaxial cable and fiber optics, and wireless media like radio waves. For each type, it provides details on their composition, usage and advantages and disadvantages compared to other media. The document also discusses common network cable connectors like RJ45, RJ11 and BNC.
Lecture 2 protocol details
Lecture 2 protocol detailsTanveer Malik The document discusses network protocols and their layered structure. It describes the seven layers of the OSI reference model and four layers of the TCP/IP model. Each layer is responsible for different aspects of network communication. The physical layer deals with physical connections. The data link layer handles data transfer between devices. The network layer performs routing and logical/physical address translation. The transport layer ensures reliable delivery of packets. The session layer allows for communication sessions. The presentation layer handles data formatting. The application layer directly supports user applications. Protocols must be configured correctly for computers to communicate over a network.
Lecture 1 networking types roles
Lecture 1 networking types rolesTanveer Malik The document discusses different types of computer network topologies. It describes bus, star, ring, and mesh topologies, and provides details on how each is structured. It also lists advantages and disadvantages of each topology type. Bus topology connects all computers to a main cable. Star topology connects all devices to a central hub. Ring topology connects all devices in a circular loop. Mesh topology connects all devices to each other so there are multiple redundant connections between devices.
Lecture 12
Lecture 12Tanveer Malik The document discusses different types of standard library functions in C/C++ including arithmetic functions, trigonometric functions, and string functions. It provides details on common trigonometric functions like sin, cos, and tan as well as arithmetic functions such as abs, log, floor, pow, and sqrt. It also covers string functions strcat and strcmp. Examples are given for many of the functions and their usage and required header files are stated. The document is copyrighted by Tanveer Malik.
Lecture 11
Lecture 11Tanveer Malik This document discusses looping statements in C programming like break, continue, and preprocessor directives. It explains that break terminates loops immediately, continue skips statements, and preprocessor directives beginning with # instruct the compiler on pre-processing like text substitution before compilation. Preprocessor directives must start in the first column with # and include commands like #include, #define, #ifdef, and more.
Lecture 10
Lecture 10Tanveer Malik This document discusses different types of loops in C programming:
1. For loops are used when the number of iterations is known and repeat until a test expression is false.
2. While loops repeatedly execute as long as a given condition is true.
3. Do-while loops are similar to while loops but always execute the block at least once even if the condition is false.
Examples of code are provided for each loop type.
Lecture 9
Lecture 9Tanveer Malik This document discusses conditional operators in C programming. It defines conditional operators as ternary operators that take three arguments: an expression to evaluate, an expression to execute if the condition is true, and an expression to execute if the condition is false. It provides the syntax for conditional operators and explains that the first expression must evaluate to true or false, with true being a non-zero result and false being a zero result. An example is given to check if a number is odd or even using conditional operators. The document concludes by assigning students to create a flow chart for conditional operators.
Lecture 8
Lecture 8Tanveer Malik This document discusses different decision making structures in programming languages, including if statements, if/else statements, nested if/else statements, and switch statements. If statements execute code if a test expression is true, and optionally other code if it is false. If/else statements execute one block of code if the test is true, and another if it is false. Nested if/else statements allow checking multiple test expressions to execute different code blocks. Switch statements provide an alternative to nested if/else statements when choosing between multiple options based on a single variable. Examples and syntax of each structure are provided.
Lecture 7
Lecture 7Tanveer Malik This document discusses various input statement functions in C programming. It covers the scanf(), gets(), getchar(), getch() and getc() functions. Scanf() is used to read numeric and string data from keyboard. Gets() reads a line from stdin and stores it in a string. Getchar() and getc() read a single character from stdin, with getchar() being equivalent to getc(stdin). Getch() is a non-standard function that reads a character without echoing it. The document provides the syntax and usage of each function.
Lecture 6
Lecture 6Tanveer Malik This document discusses various output statements in C programming including printf(), cout, clrscr(), putch(), putchar(), and puts(). It explains that output statements are used to send information to output devices. Specific functions covered include printf() for formatted output, cout for C++ output, clrscr() to clear the screen, putch() and putchar() for single character output, and puts() for string output. Format specifiers and escape sequences that can be used with these functions are also defined.
Lecture 5
Lecture 5Tanveer Malik The document discusses the sizeof operator in C/C++. It explains that sizeof returns the size of a data type or variable in integer format. It provides examples showing sizeof can be used with basic data types like char, int, float, and double to return their memory allocation sizes. The document also briefly mentions declaring variables, constants, and strings in C/C++.
Lecture 4
Lecture 4Tanveer Malik Here are the key data types in C/C++:
int - Stores integer values. Default size is usually 32 bits.
char - Stores a single character like 'a' or '5'. Size is usually 8 bits.
float - Stores fractional values. Size is usually 32 bits as per IEEE-754 standard.
double - Stores fractional values with higher precision than float. Size is usually 64 bits as per IEEE-754 standard.
void - Indicates no data type. Usually used for functions that don't return values.
bool - Stores true or false values. Size is usually 8 bits. Defined in <stdbool.h>.
Additional types include long, long long for larger integers.
Lecture 3
Lecture 3Tanveer Malik This document discusses different types of operators in C/C++ programming including arithmetic, relational, logical, and bitwise operators. It explains that operators are symbols that tell the compiler to perform mathematical or logical manipulations on data and variables. Tables are provided showing the different arithmetic, relational, and logical operators supported in C/C++ along with examples of how they would evaluate using sample variable values.

INSULIN.pptx by Arka Das (Bsc. Critical care technology)
INSULIN.pptx by Arka Das (Bsc. Critical care technology)ArkaDas54 insulin resistance are known to be involved.Type 2 diabetes is characterized by increased glucagon secretion which is unaffected by, and unresponsive to the concentration of blood glucose. But insulin is still secreted into the blood in response to the blood glucose. As a result, glucose accumulates in the blood.
The human insulin protein is composed of 51 amino acids, and has a molecular mass of 5808 Da. It is a heterodimer of an A-chain and a B-chain, which are linked together by disulfide bonds. Insulin's structure varies slightly between species of animals. Insulin from non-human animal sources differs somewhat in effectiveness (in carbohydrate metabolism effects) from human insulin because of these variations. Porcine insulin is especially close to the human version, and was widely used to treat type 1 diabetics before human insulin could be produced in large quantities by recombinant DNA technologies.

Lecture 8 disk management
- 1. Microsoft Certified Solutions Expert Lecture No.8 Disk Management Copyrights By Tanveer Malik
- 2. Disk Management • Disk Management is a Microsoft Windows utility first introduced in Windows XP as a replacement for the fdisk command. • It enables users to view and manage the disk drives installed in their computer and the partitions associated with those drives. • As can be seen in the picture below, each drive is displayed followed by the layout, type, file system, status, capacity, free space, % free, and fault tolerance. Copyrights By Tanveer Malik
- 3. Disk Management • Disk Management . • MBR. • GPT. • VHD. • Basic Disk. • Dynamic Disk. • Storage pool. Copyrights By Tanveer Malik Assignment
- 4. Master Boot Record (MBR) • The Master Boot Record (MBR) is the information in the first sector of any hard disk that identifies how and where an operating system is located so that it can be loaded into the computer's main storage or random access memory. • MBR does have its limitations. For starters, MBR only works with disks up to 2 TB in size. Copyrights By Tanveer Malik
- 5. Master Boot Record (MBR) • MBR also only supports up to four primary partitions if you want more, you have to make one of your primary partitions an “extended partition” and create logical partitions inside it. This is a silly little hack and shouldn’t be necessary. Copyrights By Tanveer Malik
- 6. Global Partition Table (GPT) • GPT is a newer standard that’s gradually replacing MBR. • GPT, in turn, replaces the old MBR partitioning system with something more modern. It’s associated with UEFI. • It’s called GUID Partition Table because every partition on your drive has a “globally unique identifier. Copyrights By Tanveer Malik
- 7. Global Partition Table (GPT) • GPT doesn’t suffer from MBR’s limits. • GPT based drives can be much larger, with size limits dependent on the operating system and its file systems. GPT also allows for a nearly unlimited number of partitions. Copyrights By Tanveer Malik
- 8. Virtual Hard Disk (VHD) • Virtual hard disk (VHD) is a disk image file format for storing the complete contents of a hard drive. • The disk image, sometimes called a virtual machine, replicates an existing hard drive and includes all data and structural elements. It can be stored anywhere the physical host can access. Copyrights By Tanveer Malik
- 9. Basic Disk • A physical disk that contains primary partitions, extended partitions, or logical drives. Basic disks can be accessed by all versions of Windows, MS-DOS, and Windows NT. • Basic disks can contain up to four primary partitions, or three primary partitions and an extended partition with multiple logical drives.
